It is required to measure and set out accurately, and the setting-out pile position is stable and firm.

(three) strict material entry system, the good raw materials. Cement and steel bars shall be identified and classified in batches during transportation and storage, and shall not be mixed. The factory certificate must be complete, and materials without material certificate and unqualified materials are not allowed to be used to ensure the engineering quality.

(4) In the engineering construction, targeted work instructions should be taken for problems prone to common quality defects and construction difficulties:

1, steel engineering, conform to the requirements of drawings and specifications, by the foreman, technicians and quality engineer level 3 inspection, ensure not to drop, not short of, not bad. The key parts, namely the column and beam slab, are welded firmly with stirrups, and positioning hoops are not used, so that the main reinforcement of the column does not move or deform, and the plate reinforcement is divided and cross-bound with stay wires. The lower point of the hook at the end of the negative bending moment steel bar of the plate is bound with the steel bar at the bottom of the plate to prevent it from moving and deforming. In order to prevent the construction personnel from stepping on the floor steel bars when pouring concrete, the floor is cast with iron, reinforced with steel bars, and paved with springboard, which moves with the pouring.

2. Formwork engineering is the key to ensure that reinforced concrete beams, columns and slabs are not deformed and feel good. The beam-slab structure of this project is relatively stereotyped, so we consider adopting high-quality stereotyped steel formwork and plywood to ensure the construction quality of the project. Beam-column joints are made of 12 thick waterproof plywood and battens, beams and columns are made of composite steel formwork, and plates are made of plywood formwork. It is required that the formwork shall be tight and not collapse, with stable support and firm internal support and external hoop, so as to truly prevent formwork from expanding, necking and slurry leakage.

3. In order to ensure the construction quality of concrete, a concrete field monitoring test group was set up during the construction. Concrete pouring shall be managed by special personnel in sections, and each section shall be watered continuously, cut by layers and vibrated by layers to ensure compactness, so that concrete is solid inside and light outside, components are square and the appearance is good.
