As far as the construction of greening projects in Changsha City is concerned, there are still many quality management problems due to the influence of various factors. Therefore, this article studies the construction quality management of landscaping projects in Changsha City, which has great reference and guiding significance for the province's greening management.

1 Overview of the construction of landscaping projects in Changsha

In recent years, Changsha City has carried out in-depth "three-year greening" campaign, resulting in a continuous increase in the area of ??green space and an increase in various greening indicators. is growing. In the past five years, Changsha City has built 45 new urban garden green spaces, more than 50 new or renovated roads, and the newly added green space totals 918.044...hm2. As of the end of 2014, the total green space area in Changsha was 5…656…hm2. Currently, the green space rate in built-up areas is 32.66, the green coverage rate is as high as 38.18, and the per capita park green space area is approximately 8.65...m2. Large park green spaces such as Binjiang Park, Yuehu Park, Du Fu Jiangge Park, Ecological Nursery, Qingzhu Lake Leisure Park, and Songya Lake Park have been built and opened one after another, and have achieved remarkable results.

2 Common quality problems in the construction of landscaping projects in Changsha

2.1 The main body of landscaping project construction and confusion

(1) There are many main construction units; The management level of construction managers is not high. The importance of landscaping is self-evident. Government agencies at all levels and various enterprises and institutions attach great importance to the construction of landscaping. As a result, there are many construction entities. However, because they are not professional and corresponding management units, their business levels and construction management levels are different. Needs to be improved. (2) The construction entities present a diversified trend and are relatively chaotic. There are not only professional gardening qualified companies, but also some construction companies, some individual contractors and farmers, and some part-time workers who do not understand gardening at all. Due to the uneven quality of personnel and qualifications, the quality of gardens varies. The local government is unable to control the quality of all projects, causing the quality of some greening projects to fall into an embarrassing situation.

2.2 The construction technology of landscaping projects is not in place

2.2.1 Lack of professional construction technicians Garden construction companies include management personnel, on-site construction personnel, logistics support personnel, post-maintenance personnel, Project settlement personnel, etc. During the construction process, on-site construction personnel include professional technical management personnel such as project leaders, technical leaders, quality personnel, safety personnel, construction workers, document workers, and mechanics. Due to the uncertainty of the timing of garden projects, construction workers in general garden companies do not support people for a long time. When there are projects, they are put together temporarily, and when there are no projects, they often work alone. 2.2.2 Lack of professional knowledge The support of most trees in Changsha City is very irregular. The author inspected the support situation of most trees in Changsha City and found that there are mainly the following problems: Most of the construction is to support first and then water. This is wrong. You should water first and then support. Because only after watering is completed, the soil ball can be completely sealed with the soil to improve the survival rate; the length of the support material is inappropriate and the purpose of support cannot be achieved; the support angle is incorrect; and the material used for bundling the support is improperly selected. All these require professional knowledge, otherwise it will seriously affect the construction quality of landscaping projects.

2.3 Lack of effective supervision of landscaping construction

Most of the Changsha City’s greening supervision departments are supervised by construction project construction supervisors, or there is no supervision team at all, resulting in a lack of supervision of landscaping project construction. The quality supervision lacks professionalism, and there is a lack of effective supervision of landscaping construction, resulting in loopholes in quality management. Compared with construction projects, garden engineering has the characteristics of randomness, openness and artistry in creation. However, there are no strict technical judgment standards for artistry, especially in aspects such as tree shape selection, pruning and shaping, pattern matching, mountain building and water management, etc. , with a certain degree of randomness and flexibility and creativity of personal aesthetic concepts, which leads to the lack of unified supervision standards in some processes of landscaping project construction, making supervision difficult.

2.4 Lack of strict management of materials and equipment involved in construction

Construction materials and equipment are an important guarantee for the quality of garden projects. Construction management personnel are required to conduct strict inspections before construction, and unqualified construction materials and equipment will not be used. But in reality, in order to save costs, shoddy products abound. The structural safety performance involved in landscaping is relatively small, and the functional requirements are basically met, so that the relevant functional departments can give acceptance and pass it.

2.5 Emphasis on construction and light on later management

"Three parts to plant, seven parts to nourish", it is urgent to explore effective maintenance management mechanisms and methods. Changsha greening project construction is generally handed over to the construction unit one year after completion. During this year, maintenance by professional companies is generally in place. However, after handover, how to strengthen later maintenance is an important part of landscaping quality management. 2.6 Winning the bid at a low price is an important hidden danger that affects quality. If a construction company wants to obtain a construction task, the bidding price is one of the key factors. The malicious competition between enterprises leads to winning bids at low prices, which brings certain quality hazards to future garden construction. Enterprises generally do not carry out construction at a loss, but in order to make up for the impact of low prices, they will undoubtedly have to sacrifice quality, cut corners and lower construction standards. Therefore, winning the bid at a low price is an important hidden danger that affects quality.

3 Countermeasures to strengthen the construction quality management of greening projects in Changsha

3.1 Strengthen the construction of garden construction subjects and construction subjects

Government agencies at all levels, enterprises and institutions Construction units such as units are investors in landscaping and enjoy investment control rights, supervision rights over construction funds and quality management, and only enjoy the right to use. Transfer the construction rights to the garden management department with professional knowledge. The garden management department will select professional construction teams for construction in a unified, open, fair and impartial manner and be responsible for the construction quality; the professional supervision unit is responsible for quality supervision and management and enjoys the right to supervise .

3.2 Improve landscaping construction technology

3.2.1 Strengthen the training of garden construction technical talents. In 2014, the Hunan Provincial Department of Urban and Rural Development and Housing Security organized 17 comprehensive projects with more than 2,000 people. Provincial landscaping project leaders are trained, strictly assessed, and certificates are issued so that they can work with certificates, which effectively improves the construction business level of the "leaders" of the construction team. At the same time, we will strengthen the training and examination of on-site construction personnel, including the "Nine Majors", and provide irregular training on the business knowledge of management personnel, designers, logistics support personnel, post-maintenance personnel, and project settlement personnel, and comprehensively strengthen the cultivation of garden construction technical talents, which is a guarantee The prerequisite and strong guarantee for the quality of landscaping projects. 3.2.2 Strengthen the training and popularization of professional theoretical knowledge. Only by improving all employees can we reduce or eliminate quality defects and ensure the improvement of construction quality. 3.2.3 Strengthen technological innovation and improve construction quality, including new construction design plans, new construction techniques, new quality management methods, innovative talent training methods, etc. Innovative methods that are conducive to improving project quality await new discoveries and practice. 3.2.4 Improve the management level of landscaping construction managers. The management level of landscaping construction managers directly affects the development of landscaping projects. Relevant rules and regulations should be formulated to regulate construction managers and constantly urge construction personnel to improve their technical levels. Strictly control the recruitment process to prevent some applicants from taking advantage of troubled waters. In addition, statistics on various construction equipment and materials at the construction site must be carried out from time to time to prevent construction workers from cutting corners.

3.3 Strengthen the effective supervision of landscaping construction

(1) It is urgent to strengthen the professional supervision team of landscaping project construction to make up for the loopholes in quality management and effectively put the creation into practice A combination of spontaneity, openness and artistry. (2) Establishing unified quality supervision standards and implementing a landscaping project supervision system are the guarantee for quality management and control of landscaping projects. Landscaping supervision not only safeguards the interests of the owners but also the interests of the construction unit. It must be honest, law-abiding, fair and scientific to ensure the quality of project construction.

In accordance with unified quality supervision standards, supervisory personnel shall track the entire process from construction to acceptance. If unqualified materials, processes, and products are found, they must be rectified in a timely manner. They must have the courage to point out existing problems and have the courage to stop discovered problems. (3) Strengthen the establishment of the supervision system, strengthen the inspection of the implementation of the system, and ensure that words and deeds are resolute, so as to ensure the construction quality of the entire project.

3.4 Strengthen the management of construction materials and equipment

(1) Construction management personnel must strictly inspect before construction, and resolutely refuse to use unqualified construction materials and equipment to prevent Or reduce the phenomenon of shoddy products due to cost saving. (2) Strengthen seedling selection management. Give priority to designated seedling supply units; when selecting seedlings, pay attention to whether the quality, height, plant type, trunk diameter and root development of the seedlings meet the specified requirements, and select high-quality seedlings that grow well and are free from diseases and insect pests; during the transport of seedlings, cover , loading, unloading, watering and other measures to protect seedlings. Ensuring that seedlings are of good quality is a key factor in ensuring effective quality management.

3.5 Strengthen the post-maintenance management of landscaping projects

At present, the relevant management departments of Changsha City have actively explored the maintenance management mechanism and implemented professional company outsourcing management. In addition, we insist on achieving "four in place", that is, maintenance personnel are in place, maintenance funds are in place, maintenance measures are in place, and daily maintenance supervision and inspection are in place to form a good and orderly operation.

3.6 Reduce low-price bids and eliminate quality hazards

(1) There is no guarantee in the bidding documents that low prices will win the bid, and the possibility of winning the bid at a low price should be minimized. (2) Ensure reasonable profit margins from the capital budget. (3) Strengthen the inspection of earmarked project funds to prevent misappropriation and ensure that the quality of the project is financially guaranteed. (4) Strictly control changes in design and engineering quantities.

The landscaping project is a complex construction project that involves a wide range of areas, many processes, and a rich variety of plant materials. It is also vital, beautiful, and artistic. In view of the fact that there are still many problems in the current construction of landscaping projects in Changsha, it is necessary for landscaping workers to actively explore new methods and ideas, strive to improve the quality of garden construction, provide reference and guidance for the development of Hunan's landscaping industry, and contribute to social development and human civilization. Make greater contributions to progress.
