Description

Technical Field

[0001] This application relates to the technical field of underground pipe galleries, and in particular to a circular underground pipe gallery that is convenient for installation. Background Art

[0002] An underground pipe gallery refers to a passage in the urban underground that is specifically used for laying various pipelines (such as water supply, drainage, electricity, communication, etc.). This structure is usually enclosed and has ventilation and drainage functions to ensure the normal operation and maintenance of the pipelines.

[0003] In the existing Chinese published patent (authorized announcement number: CN205116221U), the pipe gallery precast components and the assembled integrated pipe gallery mentioned can achieve both the structural integrity of the precast components and the convenience of transportation and on-site installation and construction operations, making the assembled integrated pipe gallery assembled with the pipe gallery precast components have stable structural strength, reliable sealing, convenient transportation, less on-site assembly construction volume, reducing transportation and installation costs, and improving installation efficiency.

[0004] Most of the existing pipe galleries are precast components, which are convenient for construction and installation. At the construction site, only the trench for laying the pipe gallery needs to be excavated to place the pipe gallery, reducing the construction difficulty. However, most of the existing connections of the pipe galleries use waterproof coatings. Due to the temperature and humidity fluctuations in the underground environment, the waterproof coatings may expand or contract, resulting in the generation of cracks. Repairing these cracks requires partial disassembly or reprocessing of the pipe gallery, which is rather inconvenient to operate. Summary of the Utility Model

[0005] The purpose of this application is to provide a circular underground pipe gallery that is convenient for installation to solve the problem that due to the temperature and humidity fluctuations in the underground environment, the waterproof coating may expand or contract, resulting in the generation of cracks.

[0006] Specifically, this application adopts the following technical solutions to achieve the above purpose:

[0007] A circular underground pipe gallery that is convenient for installation includes a bottom plate. A support is fixedly connected to the top of the bottom plate. A pipe gallery one is lapped on the top of the support. A pipe gallery two is lapped on the top of the pipe gallery one. Sealing mechanisms are symmetrically arranged on both sides of the bottom of the pipe gallery two in the left-right direction. Prefixing mechanisms are symmetrically arranged on both sides of the top of the bottom plate in the left-right direction.

[0008] By adopting the above technical solutions, use a crane or other equipment to hoist the pipe gallery one to the top of the support for installation, then hoist the pipe gallery two to the top of the pipe gallery one, then apply a waterproof coating at the connection between the pipe gallery one and the pipe gallery two, and finally backfill the soil to complete the installation of the pipe gallery one and the pipe gallery two. The sealing mechanisms can seal between the pipe gallery one and the pipe gallery two, and the pre-fixing mechanisms facilitate the subsequent construction operations for the staff.

[0009] Furthermore, the sealing mechanism includes positioning grooves symmetrically formed on both sides of the bottom of the second pipe gallery. On both sides of the top of the first pipe gallery, positioning blocks are symmetrically and fixedly connected. The positioning blocks are adapted to the positioning grooves. An airbag is arranged inside the positioning blocks. On both sides of the bottom of the second pipe gallery, a number of pressure plates are equidistantly and fixedly connected. The pressure plates are in contact with the airbag. On both sides of the top of the positioning blocks, a number of moving holes are equidistantly formed. The pressure plates are slidably arranged in the moving holes.

[0010] By adopting the above technical solution, when the second pipe gallery drives the pressure plates downward, the pressure plates enter the inside of the positioning blocks to squeeze the airbag. After being squeezed, the airbag expands outward, filling the gap between the first pipe gallery and the second pipe gallery.

[0011] Furthermore, the airbag is arranged as a long strip hole, and the outer surface of the airbag abuts against the inner wall of the positioning block.

[0012] By adopting the above technical solution, it helps the airbag to closely adhere to the positioning block during the expansion process, forming a tighter seal.

[0013] Furthermore, on both sides of the top of the first pipe gallery, a number of first inserting rods are symmetrically and fixedly connected. On both sides of the bottom of the second pipe gallery, a number of first slots are symmetrically formed. The first inserting rods are adapted to the first slots, and the first inserting rods are slidably arranged in the first slots.

[0014] By adopting the above technical solution, the installation positions of the first pipe gallery and the second pipe gallery can be accurately docked.

[0015] Furthermore, the pre-fixing mechanism includes bases symmetrically and fixedly connected to both sides of the top of the base. On both sides of the first pipe gallery, fixing plates are symmetrically and fixedly connected. At the bottom of the fixing plates, a number of second inserting rods are equidistantly and fixedly connected. On the top of the base, a number of second slots are equidistantly formed. The second inserting rods are slidably arranged in the second slots.

[0016] By adopting the above technical solution, the position of the second pipe gallery can be pre-fixed to ensure that the second pipe gallery remains in the correct position during the installation process.

[0017] Furthermore, a clamping block is fixedly connected to the bottom end of the second inserting rod. On both sides of the inner bottom wall of the second slot, stress plates are symmetrically and slidably connected.

[0018] By adopting the above technical solution, the stress plates firmly abut against the inner wall of the second slot, which helps to limit the movement range of the clamping block.

[0019] Furthermore, a metal plate is fixedly connected to the outside of the stress plate, and the outside of the metal plate is a metal rough surface.

[0020] By adopting the above technical solution, the metal rough surface of the metal plate can increase the friction between the stress plate and the inner wall of the second slot.

[0021] Furthermore, a perfusion groove is formed at the bottom of the base, and a pouring hole is formed in the inner bottom wall of the second slot, and the pouring hole is communicated with the perfusion groove.

[0022] By adopting the above technical solution, the solidified concrete can form a coherent solidified layer inside the base, improving the integrity and stability among a plurality of second inserting rods.

[0023] In summary, the present application includes at least one of the following beneficial effects;

[0024] 1. In the present application, when installing the second pipe gallery, after the airbag is squeezed, it expands outward, so that the airbag fills the gap between the first pipe gallery and the second pipe gallery, increasing the sealing strength at the connection between the first pipe gallery and the second pipe gallery, and reducing the risk of water seepage caused by possible cracks or failures of the waterproof coating.

[0025] 2. In the present application, when the second pipe gallery descends to the top of the first pipe gallery, the second inserting rod and the second slot are slidably arranged, thereby pre-fixing the position of the second pipe gallery, ensuring that the second pipe gallery remains in the correct position during the installation process, reducing the adjustment requirements caused by inaccurate positions, and facilitating the subsequent construction operations of the staff.

[0033] The following further elaborates on this application in conjunction with the Figures 1-5 accompanying drawings for a more detailed description.

[0034] An embodiment of this application discloses a circular underground pipe gallery that is convenient for installation.

[0035] Referring to Figures 1 to 3 , a circular underground pipe gallery that is convenient for installation includes a bottom plate 1. A support 2 is fixedly connected to the top of the bottom plate 1. A pipe gallery one 3 is lapped on the top of the support 2. A pipe gallery two 4 is lapped on the top of the pipe gallery one 3. Sealing mechanisms are symmetrically arranged on both sides of the bottom of the pipe gallery two 4 from left to right. Prefixing mechanisms are symmetrically arranged on both sides of the top of the bottom plate 1 from left to right.

[0036] During construction, first, the trench is excavated according to the design drawings, then the bottom plate 1 is poured into the trench, and then the support 2 is fixed to the top of the floor. The support 2 is made of concrete. Then, a crane or other equipment is used to hoist the pipe gallery one 3 onto the top of the support 2 for installation, and then the pipe gallery two 4 is hoisted onto the top of the pipe gallery one 3. Then, waterproof paint is applied to the connection between the pipe gallery one 3 and the pipe gallery two 4. Finally, the soil is backfilled to complete the installation of the pipe gallery one 3 and the pipe gallery two 4. Since the pipe gallery one 3 and the pipe gallery two 4 are prefabricated parts, the construction difficulty is reduced, achieving the advantage of convenient installation. The sealing mechanism can seal between the pipe gallery one 3 and the pipe gallery two 4, improving the sealing performance between the pipe gallery one 3 and the pipe gallery two 4. The pre-fixing mechanism can fix the pipe gallery one 3 on the top of the support 2, facilitating subsequent construction operations for the staff.

[0037] Referring to Figure 2 and Figure 3 , the sealing mechanism includes positioning grooves 5 symmetrically opened on both sides of the bottom of the pipe gallery two 4 from left to right. Positioning blocks 6 are symmetrically and fixedly connected to both sides of the top of the pipe gallery one 3 from left to right. The positioning blocks 6 are adapted to the positioning grooves 5. An airbag 7 is arranged inside the positioning blocks 6. A number of pressure plates 8 are equidistantly and fixedly connected to both sides of the bottom of the pipe gallery two 4. The pressure plates 8 abut against the airbag 7. A number of moving holes 9 are equidistantly opened on both sides of the top of the positioning blocks 6. The pressure plates 8 are slidably arranged in the moving holes 9.

[0038] Among them, the airbag 7 is arranged in a strip shape, and the outer surface of the airbag 7 abuts against the inner wall of the positioning block 6.

[0039] In addition, a number of first insertion rods 10 are symmetrically and fixedly connected to both sides of the top of the pipe gallery one 3 from left to right. A number of first slots 11 are symmetrically opened on both sides of the bottom of the pipe gallery two 4 from left to right. The first insertion rods 10 are adapted to the first slots 11, and the first insertion rods 10 are slidably arranged in the first slots 11.

[0040] When installing the second pipe gallery 4, first use a crane to slowly lower the second pipe gallery 4 above the first pipe gallery 3. At this time, the second pipe gallery 4 drives the pressure plate 8 downward. Since the pressure plate 8 is adapted to the moving hole 9, the pressure plate 8 enters the inside of the positioning block 6 to squeeze the airbag 7. After being squeezed, the airbag 7 will expand outward, filling the gap between the first pipe gallery 3 and the second pipe gallery 4, increasing the sealing strength at the connection of the first pipe gallery 3 and the second pipe gallery 4, and reducing the risk of water seepage caused by possible cracks or failures in the waterproof coating.

[0041] When the airbag 7 is forced to expand, the outer surface of the airbag 7 contacts the inner wall of the positioning block 6, which helps the airbag 7 to closely adhere to the positioning block 6 during the expansion process, forming a tighter seal. At the same time, the inner wall of the positioning block 6 provides a support surface, enabling the airbag 7 to fully expand and seal the gap between the pipe galleries. The material of the airbag 7 is nitrile rubber, which has good elasticity. During the installation process, if the airbag 7 is damaged, the staff needs to lift the second pipe gallery 4 and then replace the airbag 7. After long-term use, if the airbag 7 leaks, professional personnel need to be arranged for maintenance. During the maintenance, it is necessary to first evaluate the damaged part to determine the degree and location of the damage. If the damage is small, a professional rubber repair agent can be used for repair. If the damage is large, a new airbag 7 needs to be replaced.

[0042] When the second pipe gallery 4 moves downward, the design of the positioning block 6 and the positioning groove 5 enables the installation positions of the first pipe gallery 3 and the second pipe gallery 4 to be accurately docked, allowing the second pipe gallery 4 to move to a suitable position.

[0043] Refer to Figure 1 、 Figure 4 and Figure 5 As shown in

[0044] and

[0045] The pre-fixing mechanism includes bases 12 symmetrically and fixedly connected to both sides of the top of the base 12. Both sides of the first pipe gallery 3 are symmetrically and fixedly connected with fixing plates 13. A number of second inserting rods 14 are equidistantly and fixedly connected to the bottom of the fixing plates 13. A number of second slots 15 are equidistantly opened on the top of the base 12. The second inserting rods 14 are slidably arranged in the second slots 15.

[0046] Among them, the bottom end of the second inserting rod 14 is fixedly connected with a clamping block 16. Two sides of the inner bottom wall of the second slot 15 are symmetrically and slidably connected with stress plates 17.

[0047] When the pipe gallery 2 4 descends to the top of the pipe gallery 1 3, the pipe gallery 2 4 will drive the plug rod 2 14 downward, and the plug rod 2 14 will enter the slot 2 15 downward. The position of the pipe gallery 2 4 is pre-fixed by sliding the plug rod 2 14 and the slot 2 15, ensuring that the pipe gallery 2 4 remains in the correct position during the installation process, reducing the need for adjustment due to inaccurate position, and facilitating subsequent construction operations of the staff;

[0048] When the second insertion rod 14 is downward, the second insertion rod 14 drives the engaging block 16 downward, and the engaging block 16 will enter between the force-bearing plates 17 on both sides, and the force-bearing plates 17 on both sides will move to both sides after being stressed, so that the force-bearing plates 17 firmly contact the inner wall of the second slot 15, which helps to limit the movement range of the engaging block 16, thereby fixing the engaging block 16, and further improving the stability of the second pipe gallery 4 during the construction process;

[0049] When the force-bearing plate 17 contacts the inner wall of the second slot 15 , the rough metal surface of the metal plate 18 can increase the friction between the force-bearing plate 17 and the inner wall of the second slot 15 , so that the locking block 16 is fixed more firmly.

[0050] After the construction is completed, the staff will pour concrete inside the slot 2 15, and the concrete will enter the pouring groove 20 through the pouring hole 19, filling the gap inside the slot 2 15 with concrete, further enhancing the connection strength between the base 12 and the pipe gallery 1 3. At the same time, several slots 2 15 are connected, so that the cured concrete can form a coherent cured layer inside the base 12, thereby improving the integrity and stability between the several inserted rods 2 14.

[0051] Working principle: pour the base plate 1 in the groove, and then fix the support 2 on the top of the floor. The support 2 is made of concrete. Then use a crane or other equipment to hoist the pipe gallery 3 to the top of the support 2 for installation. Then hoist the pipe gallery 2 4 to the top of the pipe gallery 3. Then apply waterproof paint at the connection between the pipe gallery 1 3 and the pipe gallery 2 4. Finally, backfill the soil to complete the installation of the pipe gallery 1 3 and the pipe gallery 2 4. Use a crane to slowly lower the pipe gallery 2 4 to the top of the pipe gallery 1 3. At this time, the pipe gallery 2 4 drives the pressure plate 8 downward, and the pressure plate 8 is adapted to the moving hole 9, so that the pressure plate 8 enters the interior of the positioning block 6 to squeeze the airbag 7. After squeezing, the airbag 7 will expand outward, so that the airbag 7 fills the gap between the pipe gallery 1 3 and the pipe gallery 2 4, and increases the sealing strength of the connection between the pipe gallery 1 3 and the pipe gallery 2 4.

[0052] By the outer surface of the airbag 7 coming into contact with the inner wall of the positioning block 6, it helps the airbag 7 to closely adhere to the positioning block 6 during the inflation process, forming a tighter seal. At the same time, the inner wall of the positioning block 6 provides a supporting surface, enabling the airbag 7 to fully expand and seal the gap between the pipe galleries. When the second pipe gallery 4 descends to the top of the first pipe gallery 3, at this time, the second pipe gallery 4 will drive the second insertion rod 14 downward, and the second insertion rod 14 will enter the second slot 15 when it moves downward. By the sliding arrangement of the second insertion rod 14 and the second slot 15, the position of the second pipe gallery 4 is pre-fixed, ensuring that the second pipe gallery 4 remains in the correct position during the installation process.
