The Construction of Liangshan Road Showing Heroism —— On-the-spot Report of the Third Company of China Railway 16th Bureau Group Participating in the Construction of Shandong Jihe Expressway

Liangshan county, Shandong province, has a long-standing reputation, outstanding people and strong military spirit. Eight hundred miles of water, gave birth to countless heroes. In ancient times, Song Jiang, known as "filial piety and black saburo", made friends with heroes all over the world. With the natural barrier of Shui Bo, he gathered in the mountains and had a great influence on the world. So far, Wang Yanlin, the project manager of the Third Company of China Railway 16th Bureau Group, has led a good soldier to build roads here, overcome difficulties and overcome risks, and gained the reputation of Excellence.

At that time, Song Jiang led the "chivalrous man" to uphold justice for heaven here, but he was finally killed by the court and paid the price of his life. Today, Wang Yanlin led the employees involved in the construction to build roads here, work hard, benefit the people, and make great sacrifices because of difficulties.

Bear a heavy burden.

Some people say that Shandong is like a Dapeng, with the eastern coast as its wing and the western plain as its wing. The west wing is weaker than the east wing, which seriously restricts the economic development of the whole province. In order to expand the west wing and balance the eastern and western economies, Shandong Province decided to build Jinan-Heze Expressway to promote the leap-forward development of the western economy.

Total length of Jihe Expressway 154 km!

ContractNo. 12 undertaken by the third company of China Railway 16th Bureau Group is all located in Liangshan County. The total length of the line is 1 1.7km, and the road surface is 28m wide. It is designed with four lanes and the speed is 120km/h ... The main quantities are: extra large bridge 1/527m, large bridge 2/390m, medium bridge 1/53m, separated overpass 3/206.06m, overpass1/53m. Subgrade filling 1902923 cubic meters, structural abutment backfilling 58027 cubic meters, subgrade treatment powder injection pile 15 10 meter, mortar drainage ditch 2346 1 meter, mortar arch slope protection 66883 square meters, grid slope protection 9238 square meters, graded gravel subbase 6920. Lime fly ash stabilized soil base is 3 10555 m2, cement stabilized soil base is 5938 10 m2, prime coat is 309 14 1 m2, coarse asphalt concrete is 249639 m2, and modified asphalt mixture is 30914/kloc.

The Jiliang Yunhe Bridge under construction is the key and difficult project of the pipeline section. The total length of this bridge is 527 linear meters. The main span is 60+ 100+60 prestressed concrete semi-rigid frame three-span continuous box girder. The cross section of the beam is two independent single-box and single-chamber cross sections, with a width of13.5m, and adopts a three-way prestressed structure. The approach bridge adopts 30m prestressed concrete simply supported beam to transform continuous box girder. The two main piers adopt double thin-walled piers, and the approach bridge adopts column piers and ribbed slab abutment. The riverbed geology of the bridge site is: clay, loam, clayey silt, fine sand, medium sand, coarse sand and medium coarse sand. The construction of main span hanging basket bored pile foundation and prestressed concrete semi-rigid continuous box girder is the key control project of the bridge.

"Tight construction period, heavy tasks, long pipelines and many structures" are the remarkable characteristics of this contract section. Within the 1 1.7km pipeline, 37 bridges and 1 1 culverts will be built, and high-standard subgrade with a length of 10km and a width of 28m will be filled. The engineering technology is complex and the construction requirements are high, but the construction period is only 32 months. The project officially started on February 2004 10, and must be completed on August 9, 2007.

There are more than 30 administrative villages along the contract section. In this land-intensive plain area, land is the "lifeblood" of the people. A slight touch will lead to disputes and blocked work.

It is difficult to requisition the soil yard, dig deep into the flat ground to borrow soil, the soil quality is poor, the water content is large, and the transportation distance is long. The bridge design change will affect the construction period. The price of local building materials generally rises, the cost increases, the source of materials is limited, and natural disasters occur frequently, which will seriously affect the construction progress.

Draw one's sword out of its sheath

This is a battle of attack and credibility.

He led the project team to assess the situation, operate ahead of schedule and strictly implement the contract responsibility system from top to bottom; Adhere to a high starting point and high standards, and control the construction period, quality, safety and benefit to every day, every team and every construction node. They lost no time in concentrating manpower, material resources and financial resources to carry out surprise construction; Grasp the key points, overcome difficulties, work hard day and night, and go all out to successfully complete various task indicators.

In order to strengthen management and ensure quality, they strictly implement the responsibility system for construction quality, sign lifelong responsibility letters for quality at all levels, ensure that the responsibility is implemented to people and the system is put in place, ensure the quality of the project with process quality and ensure the quality of the project with work quality, and achieve the goal of "excellent quality at one time and excellent overall quality". At the same time, establish and improve the full-time quality inspection and self-inspection system, carry out all-staff and whole-process quality management activities, and constantly improve the system in operation, forming a three-level quality management network of quality inspection engineers of the project department, quality inspection engineers of the construction team and quality inspectors of the team. The project department has been equipped with 7 quality inspection engineers, 0/2 quality inspection engineers from the construction team/KLOC, and 24 quality inspectors from each team. They adhere to the theme of quality and carry out technical quality and key research activities on the construction site. The construction process is divided into key working procedures and special working procedures for the whole process quality control, which is implemented vertically in each working procedure and horizontally in everyone; The construction process is divided into general process and key process, and effective on-site monitoring is carried out to ensure the overall quality of the project. They also do a good job in popularizing and applying the "four new technologies". Through strict and standardized quality management and technological innovation, the engineering quality has been effectively improved. The bridge and culvert project under construction and the construction subgrade have achieved complete information and beautiful quality, and they are among the best in the comprehensive evaluation of Jihe Expressway. In 2005, they were rated as "advanced units in safety and quality management" by the company.
