Description

Technical Field

[0001] The present invention relates to the field of construction technology, and particularly to a permanent-temporary combined logistics channel in an extra-large foundation pit. Background Art

[0002] In building construction, for projects with a large site area and a tight construction period, in terms of material transportation, if only tower cranes are used for horizontal and vertical transportation on site, the tower cranes need to transfer materials layer by layer to hoist steel bars, formworks and other materials from the steel bar and carpentry processing plants around the large-scale building to the construction site. The material transportation efficiency is relatively low. When the surrounding site of the construction environment is relatively narrow, the pure tower crane transportation method cannot be used. At this time, it is necessary to combine tower crane transportation and a temporary logistics channel to achieve high-efficiency material transportation and accelerate the construction progress.

[0003] The currently used temporary logistics channel is directly formed by pouring concrete on the bottom surface of the foundation pit. The structural strength of the temporary logistics channel is insufficient, and it is impossible to continue the construction of the cushion layer and the floor slab on this basis. Moreover, this temporary logistics channel needs to be demolished after the main structure construction of other areas outside the logistics channel area is completed, and then the main structure of the logistics channel area is constructed. The construction volume of demolishing and cleaning the temporary logistics channel is relatively large, the construction progress is slow, and the construction cost is relatively high. Summary of the Invention

[0004] The purpose of the present invention is to solve the following disadvantages in the prior art: the structural strength of the temporary logistics channel is insufficient, and it is impossible to continue the construction of the cushion layer and the floor slab on this basis. Moreover, this temporary logistics channel needs to be demolished after the main structure construction of other areas outside the logistics channel area is completed, and then the main structure of the logistics channel area is constructed. The construction volume of demolishing and cleaning the temporary logistics channel is relatively large, the construction progress is slow, and the construction cost is relatively high. Therefore, a permanent-temporary combined logistics channel in an extra-large foundation pit is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A permanent-temporary combined logistics channel in an extra-large foundation pit includes a foundation pit body and a plurality of pipe piles arranged on the foundation pit body. A channel layer is arranged on the foundation pit body. A fixed sleeve is fixedly connected to each pipe pile, and a cover plate is arranged on each pipe pile. Two symmetrically arranged openings are formed in the cover plate.

[0007] Two installation cavities are formed in each of the fixing sleeves. A T-shaped block is connected to each installation cavity through a torsion spring. Two sliding assemblies are arranged on each of the fixing sleeves. Each sliding assembly includes a sliding rod connected to the fixing sleeve through a first spring. An installation column is connected to each installation cavity through a second spring. A sealing gasket with a square cross-section is installed above each of the fixing sleeves. Each sliding rod is fixedly connected to the corresponding sealing gasket;

[0008] A groove is formed in each of the installation columns. A cross bar is connected to the groove through a third spring. A limiting assembly is arranged in the groove. The limiting assembly includes a limiting rod slidably arranged on the installation column. The limiting rod is clamped with the cover plate. Each limiting rod is connected to the cross bar through a first hinge rod.

[0009] Preferably, two threaded rods cooperating with the corresponding cross bars are threadedly connected to each of the fixing sleeves. The two threaded rods are symmetrically arranged.

[0010] Preferably, a circular block is rotatably connected to the lower inner wall of each of the grooves. Two symmetrically arranged protrusions are fixedly connected to the circular block. Two mounting plates are fixedly connected to the groove. A plug shaft is slidably connected to each of the mounting plates. The plug shaft is clamped with the cover plate.

[0011] Preferably, a second hinge rod is hinged to each of the plug shafts. The second hinge rod is hinged to the corresponding protrusion.

[0012] Preferably, a rectangular groove is formed in each of the circular blocks. A rectangular rod is clamped in the rectangular groove. A mounting rod is slidably connected to the rectangular rod. The upper end of the mounting rod is fixedly connected to a rectangular plate.

[0013] Preferably, a handle is rotatably connected to each of the rectangular plates. Anti-slip lines are arranged on the handle. The rectangular plate is slidably connected to the groove.

[0014] Preferably, a pipe cavity is formed in each of the pipe piles. A steel plate is fixedly connected to the lower inner wall of the pipe cavity.

[0015] Preferably, longitudinal steel bar meshes are arranged on both sides of the channel layer. A structural cushion layer is arranged on the foundation pit body. The structural cushion layer is fixedly connected to the channel layer.

[0016] Preferably, a foundation bottom plate layer is arranged above the pipe piles. A first steel bar mesh layer is arranged on the upper surface of the foundation bottom plate layer. A second steel bar mesh layer is installed on the upper surface of the channel layer.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] After the cover plate is stably and firmly connected to the pipe pile and the fixing sleeve, the upper surface of the cover plate is flush with the upper surface of the channel layer at this time. The surfaces of the cover plate and the channel layer can be used as the transportation road surface. By removing each cover plate and then pouring concrete at the original position of the cover plate to form the foundation floor layer, the part of the channel layer that is higher than the structural cushion layer is buried in the foundation floor layer, which increases the connection strength between the foundation floor layer, the pipe pile, the channel layer and the structural cushion layer, enhances the strength of the structure. When it is necessary to construct the foundation floor layer in the foundation pit body, only need to remove the cover plate, and then further construct the foundation floor layer on the basis of the channel layer, without the need to break the channel layer or carry out heavy construction of cleaning, which speeds up the construction progress and also reduces the construction cost.

Specific embodiments

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0029] Referring to Figure 1-8 , a permanent-temporary combined logistics passage in an extra-large foundation pit, including a foundation pit body and a plurality of pipe piles 1 arranged on the foundation pit body. A passage layer 5 is arranged on the foundation pit body. The passage layer 5 is arranged above the bottom surface of the foundation pit body. Each pipe pile 1 is buried under the bottom surface of the foundation pit body, and the top part of each pipe pile 1 extends out of the bottom surface of the foundation pit body. A fixing sleeve 6 is fixedly connected to each pipe pile 1. A cover plate 3 is arranged on each pipe pile 1. Two symmetrically arranged openings are formed in the cover plate 3. Two installation cavities are formed in each fixing sleeve 6. A T-shaped block 12 is connected to each installation cavity through a torsion spring. Two sliding components are arranged on each fixing sleeve 6. Each sliding component includes a sliding rod 26 connected to the fixing sleeve 6 through a first spring 29. An installation column 17 is connected to each installation cavity through a second spring. A gasket 7 with a cross-section in a shape of a rectangle is installed above each fixing sleeve 6. Each sliding rod 26 is fixedly connected to the corresponding gasket 7.

[0030] A groove 14 is formed in each installation column 17. A cross bar 18 is connected to the groove 14 through a third spring. A limiting component is arranged in the groove 14. The limiting component includes a limiting rod 15 slidably arranged on the installation column 17. The limiting rod 15 is clamped with the cover plate 3. Each limiting rod 15 is connected to the cross bar 18 through a first hinge rod 20. Two threaded rods 19 cooperating with the corresponding cross bars 18 are threadedly connected to each fixing sleeve 6. The two threaded rods 19 are symmetrically arranged. When the threaded rod 19 is rotated, during the process of the threaded connection between the threaded rod 19 and the fixing sleeve 6, it will move horizontally and push the cross bar 18 to move together, and the cross bar 18 and the installation column 17 will slide relative to each other.

[0031] A circular block 16 is rotatably connected to the inner wall of the lower part of each groove 14. Two symmetrically arranged protrusions 22 are fixedly connected to the circular block 16. Two mounting plates 13 are fixedly connected in the groove 14. A plug shaft 24 is slidably connected to each mounting plate 13. The plug shaft 24 is clamped with the cover plate 3. A second hinge rod 23 is hinged to each plug shaft 24. The second hinge rod 23 is hinged to the corresponding protrusion 22. A rectangular groove is formed in each circular block 16. A rectangular rod 21 is clamped in the rectangular groove. A mounting rod 25 is slidably connected to the rectangular rod 21. The upper end of the mounting rod 25 is fixedly connected with a rectangular plate 27. A handle 28 is rotatably connected to each rectangular plate 27. Anti-slip lines are arranged on the handle 28. The rectangular plate 27 is slidably connected to the groove 14.

[0032] Clamp the rectangular rod 21 with the rectangular groove of the circular block 16, and then rotate the rectangular rod 21 and the circular block 16. In the initial state, the two second hinge rods 23 are inclined. After the circular block 16 rotates, the two second hinge rods 23 are in the same vertical plane. Each plug shaft 24 simultaneously slides relative to the corresponding mounting plate 13. After the plug shaft 24 moves, one end of it is clamped with the cover plate 3. At this time, the rectangular plate 27 is exactly directly above the groove 14. Then move the rectangular plate 27 downward. The mounting rod 25 simultaneously slides relative to the rectangular rod 21. After the rectangular plate 27 moves, it is completely in the groove 14. At this time, the cover plate 3 can be stably and firmly connected to the pipe pile 1 and the fixed sleeve 6. By pulling the handle 28, it is convenient to move the rectangular plate 27 in the vertical direction. The anti-slip lines can increase the friction between the handle 28 and the fingers.

[0033] A pipe cavity is formed in each pipe pile 1. A steel plate 8 is fixedly connected to the inner wall of the lower part of the pipe cavity. The steel plate 8 can seal the inner wall of the lower part of the pipe cavity to facilitate pouring concrete into the pipe core of the pipe pile 1 during subsequent construction. Longitudinal steel mesh 4 is arranged on both sides of the channel layer 5. A structural cushion layer 2 is arranged on the foundation pit body. The structural cushion layer 2 is fixedly connected to the channel layer 5. The longitudinal steel mesh 4 can increase the structural strength of the channel layer 5 and also facilitate the construction of different-strength concretes in the channel layer 5 and the structural cushion layer 2, thereby ensuring the pouring and forming of the concrete on both sides of the longitudinal steel mesh 4.

[0034] A foundation floor layer 11 is arranged above the pipe pile 1. A first steel mesh layer 10 is arranged on the upper surface of the foundation floor layer 11. A second steel mesh layer 9 is installed on the upper surface of the channel layer 5. The second steel mesh layer 9 is tied and fixed on the channel layer 5. The first steel mesh layer 10 is tied and fixed on the foundation floor layer 11. Both the first steel mesh layer 10 and the second steel mesh layer 9 are beneficial to improving the structural strength of the foundation floor layer 11.

[0035] In the present invention, during use, first, each cover plate 3 is connected to the corresponding pipe pile 1. During the process of the cover plate 3 moving towards the upper surface of the pipe pile 1, it will move vertically downward together with the sealing gasket 7. At the same time, the sliding rod 26 and the fixed sleeve 6 slide relative to each other. Since one end of the first spring 29 is fixedly connected to the fixed sleeve 6 and the other end is fixedly connected to the sliding rod 26, the first spring 29 is deformed simultaneously. During the process of the sliding rod 26 moving vertically downward, it will move downward together with the T-shaped block 12. The cross-section of the T-shaped block 12 is T-shaped, and the T-shaped block 12 rotates relative to the fixed sleeve 6 at the same time. Since one end of the torsion spring is fixedly connected to the T-shaped block 12 and the other end is fixedly connected to the inner wall of the installation cavity, the torsion spring is deformed simultaneously.

[0036] During the rotation of the T-shaped block 12, one end of it will move the mounting post 17 upward. The mounting post 17 is exactly located within the opening of the cover plate 3. When the surface of the cover plate 3 is in close contact with the surface of the sealing gasket 7 and the sealing gasket 7 is in close contact with the surface of the pipe pile 1, keep the position of the cover plate 3 unchanged, and then rotate the threaded rod 19. During the process of the threaded rod 19 being threadedly connected to the fixed sleeve 6, it will move horizontally and move the cross bar 18 together. The cross bar 18 and the mounting post 17 slide relative to each other. Since one end of the third spring is fixedly connected to the cross bar 18 and the other end is fixedly connected to the mounting post 17, the third spring is deformed simultaneously. One end of the first hinge rod 20 is hinged to the cross bar 18 and the other end is hinged to the corresponding limiting rod 15. The included angle between the two first hinge rods 20 becomes larger. During the sliding of the first limiting rod 15, one end of it will be clamped with the cover plate 3. Then, the rectangular rod 21 is clamped with the rectangular groove of the circular block 16, and then the rectangular rod 21 and the circular block 16 are rotated. In the initial state, the two second hinge rods 23 are inclined.

[0037] After the circular block 16 rotates, the two second hinge rods 23 are in the same vertical plane. Each insertion shaft 24 slides relative to the corresponding mounting plate 13 at the same time. After the insertion shaft 24 moves, one end of it is clamped with the cover plate 3. At this time, the rectangular plate 27 is exactly directly above the groove 14. Then, move the rectangular plate 27 downward. The mounting rod 25 and the rectangular rod 21 slide relative to each other at the same time. After the rectangular plate 27 moves, it is completely within the groove 14. At this time, the cover plate 3 can be stably and firmly connected to the pipe pile 1 and the fixed sleeve 6, and the upper surface of the cover plate 3 is flush with the upper surface of the channel layer 5. The surface of the cover plate 3 and the surface of the channel layer 5 can be used as a transportation road surface. Similarly, the cover plate 3 can also be removed.

[0038] By removing each cover plate 3 and then pouring concrete at the original position of the cover plate 3 to form the foundation floor layer 11, the part of the passage layer 5 that is higher than the structural cushion layer 2 is embedded in the foundation floor layer 11, which increases the connection strength between the foundation floor layer 11, the pipe pile 1, the passage layer 5 and the structural cushion layer 2, enhancing the strength of the structure. When it is necessary to construct the foundation floor layer 11 in the foundation pit body, only the cover plate 3 needs to be removed, and then the foundation floor layer 11 can be further constructed on the basis of the passage layer 5. There is no need to break the passage layer 5 or carry out heavy construction for cleaning, which speeds up the construction progress and reduces the construction cost at the same time.

[0039] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
