Description

Technical Field

[0001] This utility model relates to the field of bored pile construction technology, and in particular to a bored pile construction operation platform. Background Technology

[0002] Drilled cast-in-place piles are commonly constructed using the mud wall protection method. After drilling, a lengthy cleaning process and frequent mud performance testing are required. When pouring concrete for the pile foundation, the tremie method is commonly used. When lowering the tremie pipe into the borehole, a long, narrow valve is typically placed at the borehole opening. The tremie pipe is then secured to the valve for extension or disassembly. Workers frequently need to move around the pile hole during cleaning, testing, and pouring. However, the area around the borehole opening is often unhardened soil, which becomes muddy and slippery after rain, making movement and operation difficult and posing safety hazards. Utility Model Content

[0003] The technical problem this invention aims to solve is to provide a drilling and grouting pile construction operation platform, addressing the aforementioned technical deficiencies. This platform provides horizontal protection, improves the working environment, is easy to fold and store, reduces space occupation, and is convenient to carry and use.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a drilling and grouting pile construction operation platform, including a frame, a grid frame welded inside the frame, a patterned steel plate welded to the upper end of the frame, a double door in the middle of the patterned steel plate, the double door being hinged to the patterned steel plate, a circular through hole in the middle of the double door, and four auxiliary platforms on the outside of the frame.

[0005] Furthermore, the two longitudinal parallel beams of the grid frame are each provided with several insertion holes, and the insertion holes are connected to the corresponding positions of the patterned steel plate.

[0006] Furthermore, four of the insertion holes of the grid frame correspond to the inner wall of the steel casing, and pins are inserted into the insertion holes to prevent the platform from moving.

[0007] Furthermore, the pin has a T-shaped structure and can be fixedly installed in the socket.

[0008] Furthermore, the patterned steel plate is welded to the grid frame.

[0009] Furthermore, the circular through hole in the middle of the double door is semi-circular and symmetrical on each side of the door, and the diameter of the circular through hole is equal to the outer diameter of the infusion conduit.

[0010] Furthermore, the double door is equipped with two handles.

[0011] Furthermore, the sub-platform is a steel grating structure, and each sub-platform is hinged to the frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. Full horizontal protection of pile holes not only increases the safety of workers but also ensures their working environment and improves work efficiency;

[0014] 2. The platform is highly adaptable and can be fixed with appropriate insertion pins according to the diameter of the pile hole to prevent the platform from moving.

[0015] 3. Setting up a secondary platform can improve the working environment around the pile hole and enhance safety; the secondary platform is movable, making it easy to store and move. Attached Figure Description
