The construction of concealed procedures shall be carried out in strict accordance with regulations, specifications and operation instructions.
(7) Parapet coping reinforcement (including quantity and specification).
(2) Column, beam, stair and slab reinforcement (including quantity, specification, variety, overlapping length, welding condition, thickness of protective layer, stirrup spacing, embedded parts, etc., once per layer), patrol inspection and on-site record.
(4) Acceptance record of pile position axis deviation and elevation (if the elevation of pile top is the same as that of the construction site, it shall be carried out after the construction of pile foundation works).
(6) The supervision company shall conduct spot check on the concealed works, check the construction records and material quality certificates, and sign on the concealed works acceptance certificate after confirmation.
▼ pay attention to construction engineers and obtain the latest national construction policies and data.
(3) Cushion (including elevation, length, thickness, width and concrete strength grade).
(6) Foundation wall (including elevation, large foot size and masonry mortar strength): mortar grading sheet.
(7) Detail works: connection nodes of embedded parts (or post embedded parts), guardrails and embedded parts.
(3) After the construction of concealed procedures is completed, the construction records must be filled in after passing the self inspection by the construction director, and signed by the team leader, quality inspector, technician and inspector, and then signed by the on-site supervisor.
After concealed works are concealed, if quality problems occur, they need to be covered and covered again, which will cause great losses such as rework.
(3) Precast pile connection, bored pile drilling and hole cleaning, reinforcement cage fabrication, hoisting and concrete pouring.
(5) The isolation layer between the rigid protective layer and the coiled material and film waterproof layer.
