Description

Technical Field

[0001] This utility model belongs to the field of building engineering, and in particular relates to prefabricated foundation pit transportation channels. Background Technology

[0002] In the construction of deep foundation pit projects, on-site work vehicles need to enter and exit the foundation pit through access channels. In conventional deep foundation pit construction, traditional earthen ramps and reinforced concrete are often used for access channels. This type of construction is not only time-consuming and labor-intensive, but the access channels are also disposable. Therefore, a prefabricated access channel is needed to ensure that the support around the foundation pit is constructed simultaneously, effectively shortening the construction period. Utility Model Content

[0003] The purpose of this utility model is to provide a prefabricated foundation pit transportation channel to solve the problems existing in the prior art. To achieve the above-mentioned objective, the technical solution adopted by this utility model is as follows:

[0004] A prefabricated excavation pit transport channel includes a support structure, crossbeams, straight plates, curved plates, and protective components. Each support component comprises a base column vertically connected to at least one supporting column and a support frame threaded to the top of the base column. The support structure includes two vertically positioned support components on the ground and a crossbeam threaded to the top of both. Protective components are symmetrically arranged at both ends of the crossbeam, with adjacent protective components connected sequentially. Multiple sets of support structures are evenly arranged at the bottom of the straight plates and curved plates. At least one straight plate is sequentially connected to form a straight plate path, and at least one curved plate is sequentially connected to form a curved plate path. A curved path is provided between two straight plate paths.

[0006] Furthermore, multiple sets of fixed bases are symmetrically provided at both ends of the bottom of the straight plate and the curved plate, and two fixed bases are symmetrically provided at the top of the crossbeam. The fixed bases are threadedly connected to the fixed bases. Multiple horizontally arranged anti-slip lines are evenly provided along the length direction at the top of the straight plate and the curved plate.

[0007] Furthermore, the supporting base column includes a column body, a blind hole at the top of the column body with an internal thread inside the blind hole, a screw rod at the bottom of the column body that is adapted to the internal thread, a fixed base three on the side wall of the column body, and a fixed base four symmetrically arranged at the bottom of the crossbeam. A connecting rod is threaded between the fixed base three and the fixed base four that are close to each other; the screw rod one at the top is threaded to the blind hole at the bottom.

[0008] Furthermore, the support frame includes a U-shaped block and a second screw rod. The top of the second screw rod is fixedly provided with the U-shaped block, and the crossbeam is internally threaded to the U-shaped block. The blind hole of the topmost support column is threaded to the second screw rod.

[0009] Furthermore, the protective component includes protective posts symmetrically arranged at both ends of the crossbeam. Each protective post has a plurality of limiting holes evenly arranged along its length. Each protective post has a plurality of cavities evenly arranged inside it. The cavities are connected to the limiting holes, and the centers of the cavities and the limiting holes coincide. Each protective post has pressing holes on its two sides away from the limiting holes. The pressing holes are connected to the cavities. Each cavity and pressing hole has a limiting element. The bottom of the protective post has a screw rod three, which is threadedly connected to the crossbeam.

[0010] Furthermore, the limiting component includes two limiting blocks arranged symmetrically vertically and two pressing blocks arranged symmetrically horizontally. A rotating rod is rotatably and symmetrically provided between each pressing block and each limiting block. The pressing block is slidably connected to the pressing hole, and the limiting block is slidably connected to the cavity.

[0022] like Figure 2 , 6 As shown, the straight plate 1 includes a straight plate surface 101. A fixing plate 104 is symmetrically arranged on both sides of one end of the straight plate surface 101, and a fixing hole 1041 is provided on the fixing plate 104. A second fixing hole 105 is symmetrically arranged on both sides of the other end of the straight plate surface 101. The curved plate 2 includes a curved plate 201. The fixing plate 104 is symmetrically arranged on both sides of one end of the curved plate 201, and a second fixing hole 105 is symmetrically arranged on both sides of the other end. The fixing hole 1041 is threadedly connected to the second fixing hole 105 by a screw. The curved plate 201 has a fan-shaped cross-section when viewed from above. The straight plate surface 101 and the curved plate 201, or another straight plate surface 101, are connected. In this example, the width of the straight plate surface 101 is 4m and its length is 5m. The inner radius of the curved plate 201 is 2m, the outer radius of the curved plate 201 is 6m, and the arc angle is 10°.

The bottom of the column body 402 has a screw rod 401 adapted to the internal thread. A fixed base 403 is provided on the side wall of the column body 402. A fixed base 603 is symmetrically provided at the bottom of the crossbeam 6. A connecting rod 604 is threaded between the fixed bases 403 and 603, which are close to each other. The fixed base 603 is close to the middle part of the crossbeam 6, and the connecting rod 604 supports the middle part of the crossbeam 6. The supporting frame 5 includes a U-shaped block 502 and a screw rod 501. The top of the screw rod 501 is fixed with the U-shaped block 502, and the U-shaped block 502 is internally threaded. The crossbeam 6 has a blind hole 404 at the top of the supporting column 4 that is threadedly connected to the second screw 501; the first screw 401 at the top is threadedly connected to the blind hole 404 at the bottom, and the first screw 401 at the bottom is connected to a threaded hole pre-embedded in the ground. The length of the supporting column 4 is fixed. The length of the support frame 5 on the supporting column 4 can be adjusted by rotating it, so as to support the crossbeam 6 at different heights. The tilt angle of the straight plate 1 and the curved plate 2 can be controlled by adjusting the height difference near the crossbeam 6. It should be noted that the height difference of the crossbeam 6 at the bottom of the same straight plate 1 or curved plate 2 is consistent. If the total length of the support frame 5 and the single supporting column 4 is less than the height of the crossbeam 6, the number of supporting columns 4 can be increased.

At least one spring 708 is symmetrically provided at the ends of the two limiting blocks 706 that are far apart from each other. The other end of the spring 708 is connected to the inner wall of the cavity 707. The ends of the two limiting blocks 706 that are close to each other are provided with arc-shaped parts. The spring 708 compresses the two limiting blocks 706 inward. The two arc-shaped parts abut against the annular groove 802 to limit the hollow protective rod 8. When the pressing block 704 is pressed inward, the rotating rod 705 pushes the limiting blocks 706 to both sides to release the limitation on the hollow protective rod 8. The protective component also includes hollow protective rods 8 connected in sequence. Each hollow protective rod 8 includes a large end 803 and a small end 801. The large end 803 is provided with an annular groove 802. The outer diameter of the small end 801 is adapted to the inner diameter of the large end 803.

[0025] Working principle: Each support column 4 is threaded into the pre-embedded threaded hole in the ground. A support frame 5 is connected to the top of each support column 4. A crossbeam 6 is erected on the support frame 5 at the same horizontal height. A straight plate 1 or a curved plate 2 is connected to the top of the crossbeam 6. The straight plate 1 is connected to another straight plate 1 or curved plate 2. Then, protective columns 7 are set on both sides of the crossbeam 6. A hollow protective rod 8 is set between two adjacent protective columns 7. The large end 802 of the hollow protective rod 8 is limited by the arc part, and the small end 801 is limited by the hollow sleeve in the large end 803.
