Supervision work Instruction Detailed rules for civil engineering supervision
The allowable deviation value of each subdivisional work shall be included in 1.3 Introduction to Engineering Building/Structure/Water Supply and Drainage/Strong and Weak Current 1. The ground shall be compacted with plain soil, and the height of backfill shall be 50 mm higher than the outdoor elevation. Cast in situ floor slab. 2. Doors and windows: 3. Decoration: exterior decoration, interior painting, 1:3 cement mortar roughening in the toilet, and the surface course shall be provided by the user. 4. Roof: 5. Foundation structure; The foundation of the project is: C for cushion, C for foundation, C for constructional column and girder, MU solid bricks for bricks below the damp proof course, M5 cement mortar masonry, and MU porous clay bricks for bricks above the damp proof course. For the buried depth of foundation, the indoor floor elevation of the project ± 0.000 is equivalent to the absolute elevation m, and the indoor and outdoor elevation difference is m. 6. Main structure: 7. Water supply and drainage, electrical overview 7.1 UPVC water supply pipe is used for indoor water supply pipe, socket bonding, and galvanized steel pipe is used for outdoor connection with screw thread. 7.2 The indoor fire pipe shall be galvanized steel pipe with screw connection, and the outdoor fire pipe shall be cast iron pipe with asbestos cement interface. 7.3 Drainage pipes: UPVC drainage pipes are used indoors for wastewater and sewage pipes, and UPVC drainage pipes are used outdoors for rainwater pipes and sewage pipes. 7.4 Electrical engineering: the power supply is 380/220 V, the indoor wire tube is concealed, and the flame retardant rigid plastic tube is used. (The above contents should reflect the characteristics and technical content of the project as much as possible) 5 Detailed rules for the implementation of supervision of subdivisional and divisional works 5.1 Detailed rules for the implementation of supervision of foundation and foundation works 1 Temporary or permanent drainage ditches should be set up in the construction area before earthwork excavation, and roads for mechanical operation in the construction site should be built. Main trunk lines should be built in combination with permanent roads, The turning shall meet the safety requirements. 2 When mechanical excavation is used for foundation pit (groove) and pipe trench, a layer shall be reserved above the base elevation for manual cleaning in order not to damage the structure of the base soil. 3 The foundation shall not be exposed for a long time after excavation, and the foundation trench acceptance shall be organized in time for the construction of the next process. 4 The concrete shall be poured continuously, and construction joints shall not be left. If they must be left, they shall be left and treated according to the requirements of construction specifications. 5 The foundation surface shall be covered and watered for curing, and the foundation shall be prevented from soaking. 6 The quality inspection standard shall be in accordance with the Code for Acceptance of Construction Quality of Building Foundation Engineering. 5.2 Detailed Rules for the Supervision of Brickwork 68 pages
