What are the engineering construction methods?

Special construction scheme that all construction projects need to do.

(1) Foundation pit support and dewatering engineering

Foundation pit supporting engineering refers to the excavation of foundation pit (groove) and the construction of supporting structure with a depth of more than 5m (including 5m); Or the foundation pit is less than 5m, but the geological conditions and surrounding environment are complex, and the groundwater level is above the pit bottom.

(2) Earthwork excavation works

Earthwork excavation refers to the earthwork excavation of foundation pits and troughs with excavation depth exceeding 5m (including 5m).

(3) Formwork engineering

All kinds of tool template engineering, including sliding mode, climbing mode, large template, etc. Formwork support system for horizontal concrete members and formwork engineering for special structures.

(4) Lifting and hoisting works

(5) Scaffolding engineering

1, floor-standing steel pipe scaffold with height over 24m;

2. Attach lifting scaffolding, including integral lifting and sectional lifting;

3. Cantilever scaffolding;

4. Portal scaffolding;

5, hang scaffolding;

6, hanging basket scaffolding;

7. Unload the platform.

(6) Demolition and blasting engineering

Manual, mechanical or blasting demolition projects.

(seven) other dangerous projects.

1, installation and construction of building curtain wall;

2. Tension construction of prestressed structure;

3. Tunnel construction;

4, bridge engineering construction (including bridging);

5, special equipment construction;

6, grid and cable-membrane structure construction;

7, more than 6m slope construction;

8. River diversion and closure construction;

9, port engineering, waterway engineering;

10, the adoption of new technologies, new processes and new materials may affect the quality and safety of construction projects, and the administrative license has been obtained without technical standards.

Every region and every company has different requirements. We also require: 1, safety construction organization design 2, three treasures, four-port and adjacent enclosure special scheme 3, tower crane installation and dismantling special scheme (including basic calculation) 4, derrick or construction elevator dismantling construction scheme 5, derrick (construction elevator) unloading platform calculation scheme 6, various emergency plans 7, anti-falling shed erection scheme 8, cantilever steel platform design scheme.
