If there is a pile foundation, pile foundation construction should be carried out first; If there is a basement, the basement floor and wall shall be constructed after the cushion is completed, then the waterproof layer shall be made, the basement roof shall be installed, and finally the backfill shall be carried out.
2. Construction sequence of main structure engineering: scaffolding, installation of vertical transportation machinery, wall masonry, installation of doors and windows and lintels, reinforced concrete ring beams, constructional columns, stair pouring, precast slab or cast-in-place floor slab, cast-in-place reinforced concrete floor slab and canopy hoisting.
3. Construction sequence of roofing and decoration engineering: roofing waterproofing is generally divided into flexible waterproofing and rigid waterproofing, and flexible waterproofing is usually adopted, that is, coiled material waterproofing. The construction sequence is: structural layer → leveling layer → gas barrier layer → insulation layer → leveling layer → cold priming oil bonding layer → waterproof layer → protective layer. Roof waterproofing should start as soon as possible after the main structure is capped, providing conditions for decoration engineering construction.
Extended data:
On-site safety production and civilized construction inspection before construction:
1. Routine inspection: refers to the daily inspection organized by the project manager or the regular spot check organized by the construction enterprise. The supervision engineer shall participate in such self-inspection activities, review and sign the activity records, and urge the rectification.
2. Special inspection: According to the civilized construction management documents issued by the Municipal Construction Committee, such as digging and transporting mud and dregs, sanitation and epidemic prevention, etc. Management information, publicity and education inspection, as well as special inspection or inspection of key projects and parts carried out according to relevant documents of superiors.
3. Joint inspection: refers to the inspection conducted by the supervision team in three stages in the construction process according to the Standard for Safety Inspection of Building Construction (i.e. the foundation, main structure and the first three stages before the project is completed). The scoring results shall be signed by the project manager or the person-in-charge of the construction enterprise and the person-in-charge of the supervision company as the main basis for evaluating the construction safety level after the completion of the project.
