Technical Field

[0001] The present application relates to the technical field of pipe pit support structures, and specifically to a pipe pit support structure. Background Art

[0002] The pipe pit support structure is a protective structure used to support and protect various engineering pipelines such as electricity, communications, gas, heating, water supply and drainage. The foundation pit support measures are very important. The foundation pit support not only has to bear the soil pressure, but also the temporary earth load during earth excavation, the static load and dynamic load of construction machinery, etc., which can effectively prevent the pipeline from being damaged by the pressure of the soil.

[0003] For example, a Chinese patent (publication number: CN219364634U) discloses a tunnel foundation pit support structure, including a No. 1 pile wall and a No. 2 pile wall, wherein the bottom end of the No. 1 pile wall facing the No. 2 pile wall is fixedly connected with a folding base, and an adjustment base plate is rotatably connected inside the folding base, and a accommodating base is provided on the side of the No. 2 pile wall facing the No. 1 pile wall, and an adjustment base plate is placed inside the accommodating base, and a threaded rod is threadedly connected between two adjacent adjustment base plates, a limiting groove is provided at the bottom of one side of the adjustment base plate, and a limiting block is arranged inside the limiting groove, and a spring is fixedly connected to one side of the limiting block, and one end of the spring away from the limiting block is fixedly connected to the inner side of the folding base, and by providing the folding base, the adjustment base plate, the accommodating base, the No. 2 pile wall, the spring, the limiting block and other parts, the simple installation of the tunnel foundation pit support structure is realized, thereby improving the convenience of the tunnel foundation pit support structure.

[0004] However, the above-mentioned search patent still has some shortcomings. When in use, it is relatively convenient to install the extended pile wall, and the extended pile wall can be installed according to the buried depth of the pipeline. However, in actual use, there is a lack of relative support between the extended pile walls installed on both sides of the pipeline, which reduces the compressive strength of the extended pile wall and causes certain inconveniences in use. Therefore, a pipe pit support structure is proposed to solve the above problems. Utility Model Content

[0005] In response to the shortcomings of the prior art, the present application provides a pipe pit support structure having the advantages of high structural strength and strong compressive resistance, which solves the problem that the extended pile wall of the support structure disclosed in the above-mentioned search patent lacks support and has weak compressive resistance.

[0011] Furthermore, the control assembly includes two partitions fixed inside the square cylinder, a screw rotatably connected to the opposite sides of the two partitions and threadedly connected to the square rod, a driving rod rotatably connected to the top surface of the square cylinder, a main bevel tooth fixed to the bottom end of the driving rod, and a slave bevel tooth fixed to the end of the screw away from the square rod and meshing with the main bevel tooth.

[0012] By adopting the above technical solution, the screw rod can be driven to rotate by rotating the driving rod, so that the square rod can slide and adjust inside the square tube, which is convenient for adapting to the distance between the two steel sheet pile walls and improving the flexibility of assembly construction.

[0013] Furthermore, the support mechanism is provided in multiple groups and is evenly distributed front and back between the two steel sheet pile walls and the two extension walls. The left and right sides of the square tube are both open, and the outer peripheral wall of the square rod is matched with the inner peripheral wall of the square tube.

[0014] By adopting the above technical solution, the supporting mechanism can be adjusted by means of the square tube and the square rod, so as to adapt to the distance between the two steel sheet pile walls and improve the flexibility of assembly construction.

[0015] Furthermore, the insertion rod and the insertion pin both vertically penetrate the rectangular block, the slot is connected to the rectangular hole in a cross shape, and the circular hole is vertically opposite to the slot.

[0016] The above technical solution makes it easy to position and fix the rectangular block by cooperating with the insertion rod and the insertion pin.

[0017] Furthermore, a thread groove for threaded connection of a screw rod is provided on one side opposite to the two square rods, and a hexagonal column is fixed on the top of the driving rod.

[0019] Furthermore, support plates are fixed to the front and back sides of the square tube, a positioning rod is fixed to the top surface of the support plates, and a support plate is arranged between two adjacent support plates in the front and rear directions.

[0020] By adopting the above technical solution, the support plates arranged between the square tubes can also enhance the support effect on the soil on the top of the pipeline, reduce the pressure of the soil above the pipeline on the pipeline, and further increase the support and protection effect.

[0021] Furthermore, the bottom surface of the support plate abuts against the top surface of the support plate, the front and rear sides of the support plate abut against two adjacent front and rear square tubes respectively, and a positioning hole for a positioning rod to pass through is provided on the top surface of the support plate.

[0038] In this embodiment, thread grooves for the screw rod 502 to be threadedly connected are provided on opposite sides of the two square rods 302 , and a hexagonal column is fixed on the top of the driving rod 503 .

[0040] When the supporting mechanism 3 is installed and the soil is backfilled, the supporting plate 8 can be placed between the two square tubes 301, and the positioning rod 7 can pass through the positioning hole to limit the supporting plate 8. At this time, the pressure of the backfilled soil will act on the supporting plate 8 and then be applied to the steel sheet pile wall 1 and the extension wall 4, further improving the supporting and protective effect.

[0041] The working principle of the above embodiment is:

[0042] (1) When in use, after fixing two steel sheet pile walls 1 inside the foundation pit, the pipeline 2 can be installed between the two steel sheet pile walls 1 and the soil is backfilled to bury the pipeline 2 and the steel sheet pile walls 1. The steel sheet pile walls 1 can effectively block the pressure of the soil on the pipeline 2, thereby protecting the pipeline 2. Take out the supporting mechanism 3, insert the rectangular blocks 303 at both ends of the supporting mechanism 3 into the rectangular holes 306 on the two steel sheet pile walls 1 respectively, and then place the extension wall 4 on the top of the steel sheet pile wall 1, and make the insertion rod 30 at the bottom thereof 4 is inserted into the slot 308 on the steel sheet pile wall 1 and penetrates the rectangular block 303 inside the steel sheet pile wall 1 through the circular hole 307, so that the supporting mechanism 3, the extension wall 4 and the steel sheet pile wall 1 are fixed, and the two steel sheet pile walls 1 can be supported and reinforced by the square rod 302 and the square tube 301, and then the soil can be backfilled slowly. When the extension wall 4 needs support, the supporting mechanism 3 can be taken out, the rectangular block 303 can be inserted into the rectangular hole 306 inside the extension wall 4, and the rectangular block 303 can be fixed by the pin 305.

[0043] (2) When the support mechanism 3 needs to be adjusted according to the spacing between the two steel sheet pile walls 1, the driving rod 503 is rotated, and the driving rod 503 drives the main bevel gear 504 to rotate, and the main bevel gear 504 drives the two slave bevel gears 505 to rotate synchronously in opposite directions. Further, the two slave bevel gears 505 drive two screws 502 with the same thread direction to rotate synchronously in opposite directions, thereby driving the two square rods 302 to slide and adjust inside the square tube 301, so that the support mechanism 3 can adapt to the spacing between the two steel sheet pile walls 1. When the support mechanism 3 is installed and the soil is backfilled, the support plate 8 can be placed between the two square tubes 301, and the positioning rod 7 is passed through the positioning hole to limit the support plate 8. At this time, the pressure of the backfilled soil will act on the support plate 8 and then be applied to the steel sheet pile wall 1 and the extension wall 4, further improving the support and protection effect.
