Detailed ways

The present application will be described in further detail below in conjunction with accompanying drawings 1-3.

The embodiment of the present application discloses an enclosure structure for a foundation pit occlusal pile foundation. Referring to Fig. 1-Fig. 2, an enclosure structure of a foundation pit occlusal pile foundation comprises a foundation pit matrix 1 and an interlocking pile 2 arranged on the inner wall of the foundation pit matrix 1, and a foundation pit groove 5 is opened inside the foundation pit matrix 1, First excavate the foundation pit groove 5 to form a construction space, and then construct the interlocking pile 2 on the inner wall of the foundation pit groove 5 to stop water and retain soil. The second retaining pile 6, and the corners of the outer walls of the first retaining pile 4 and the second retaining pile 6 are welded with a reinforced positioning block 7 for positioning, and the reinforced positioning block 7 can be constructed to make it go deep into the base of the foundation pit 1 Position the corners of the inner wall, and then fix the first enclosure pile 4, the second enclosure pile 6 and the occlusal pile 2;

Reinforcement plates 8 can be disassembled inside the first enclosure pile 4 and the second enclosure pile 6, and the side walls of the reinforcement plate 8 are fixed with a fixed block 9 in an integrated structure, and the fixed block 9 can be fixed by reinforcing bolts , so that the first surrounding pile 4 and the second surrounding pile 6 can be installed on the inner wall of the occlusal pile 2, and at the same time, a number of positioning holes are equidistantly opened inside the reinforcing plate 8, and positioning piles 10 are inserted into the positioning holes. Insert the positioning pile 10 into the positioning hole. Since the bottom of the positioning pile 10 is set in a pointed shape, when pressure is applied to the top of the positioning pile 10, it will be inserted into the ground for positioning. The double protection of the matrix 1 avoids collapse under force and ensures the support strength.

By adopting the above technical scheme, the first enclosure pile 4 and the second enclosure pile 6 are successively installed at the corners of the inner wall of the foundation pit groove 5 from top to bottom to support the middle and bottom of the foundation pit groove 5, and then several A positioning pile 10 is built into the reinforcing plate 8 for strengthening and protection, forming a double support force, so that the surrounding force of the occlusal pile 2 is evenly stressed, and the overall compressive capacity of the occlusal pile 2 is improved. The reason is that some soils are relatively soft, which is easy to cause the problem of subsidence at the corners of the foundation pit.

Referring to Figures 1-3, there is a pressure-bearing mechanism for support connected between the inner walls at both ends of the foundation pit matrix 1. , set multiple groups of pressure-bearing mechanisms for support, and the pressure-bearing mechanisms include reinforced piles 3 and pressure-bearing beams 13, and one end of the two reinforced piles 3 close to each other is symmetrically distributed with a group of armored columns 11, and the armored columns 11 and the pressure-bearing beams 13 is slidingly connected, the pressure beam 13 is provided with a sliding hole near the center of one end of the armored column 11, and the armored column 11 extends to the inside of the sliding hole to provide the middle support force of the pressure beam 13.

By adopting the above technical solution, the pressure-bearing mechanism provides the top supporting force of the foundation pit base 1, forming a stable supporting force around the inner wall of the foundation pit base 1, making the overall installation of the occlusal pile 2 more firm, and avoiding the collapse of the occlusal pile that is difficult to load the foundation pit. The pressure brought by it is easy to produce bending, which in turn causes the problem of foundation pit collapse.

Referring to Fig. 3, one end of the two pressure beams 13 close to each other is fixedly equipped with a threaded joint 15, the external thread of the threaded joint 15 is connected with a threaded sleeve 16, and the inner wall of the threaded sleeve 16 is symmetrically provided with a threaded joint. 15 are all compatible reverse threads, and a turntable 17 is also welded on the outer wall of the threaded sleeve 16. By being provided with a turntable 17, it is convenient to adjust the threaded sleeve 16 to rotate, increasing the focus point, and at the corners of the armored column 11 surface There are support rods 12 for support, and the corners of the outer walls of the pressure beams 13 are welded with support sliders 14 adapted to the support rods 12. When the support position of the pressure beam 13 is adjusted, the support sliders 14 It will then slide outside the support rod 12, thereby ensuring the support force at the corners of the pressure beam 13 and avoiding the deviation of the pressure beam 13.

By adopting the above-mentioned technical scheme, after the reinforced pile 3 is constructed, the turntable 17 can be rotated forward according to the diameter distance of the foundation pit base 1, and then the threaded sleeve 16 can be driven to rotate on the outer wall of the threaded joint 15, and then the threaded sleeve 16 can be driven The two threaded joints 15 are separated from each other in the threaded sleeve 16, and at the same time, the pressure bearing beam 13 is driven to slide on the outer wall of the armored column 11 to be close to the reinforcement pile 3, so as to realize the support between the two reinforcement piles 3, Simultaneously, the supporting slider 14 will be supported on the outer wall of the supporting rod 12 as the bearing beam 13 moves, so as to play an auxiliary sliding role.
