Description

Technical Field

[0001] This utility model relates to the field of pipe gallery engineering technology, specifically to a spliced ​​prefabricated cover plate for pipe gallery roof. Background Technology

[0002] A utility tunnel is an underground public tunnel that integrates urban municipal pipelines such as water supply, rainwater, sewage, reclaimed water, natural gas, heat, electricity, and communications. To facilitate the construction and subsequent maintenance of the utility tunnel, precast cover plates are usually used to seal its upper part.

[0003] Chinese patent provides a prefabricated integrated utility tunnel, publication number CN213417893U, which includes a placement box. The placement box is a hollow rectangular box with an opening on the side. A hydraulic telescopic cylinder is installed inside the placement box. Two sets of adapter columns are fixedly installed at the output end of the hydraulic telescopic cylinder. Clamping grippers are fixedly installed at the ends of the two sets of adapter columns away from the hydraulic telescopic cylinder.

[0004] The aforementioned device, through the support rods, not only supports the precast cover plate but also creates a certain gap between the precast cover plate and the reinforcing cage, ensuring the protection of the upper reinforcing steel layer. At the same time, the self-weight and load of the precast cover plate can be transferred to the foundation layer through the support rods. With the installation of the precast cover plate, the concrete of the pipe gallery floor slab can be poured in one go, improving the durability of the pipe gallery floor slab and reducing the overall cost of the pipe gallery floor slab; it also avoids the need for secondary leveling of the pipe gallery floor slab and speeds up the construction progress.

[0005] However, when using precast cement concrete, the shape is usually rectangular. After installation, the gaps between each cover plate are relatively large. Although waterproofing is carried out, it is still easy to leak when the waterproofing layer is accidentally damaged and it rains. Furthermore, there is no positioning measure between the precast cover plates, and installation can only be done based on experience. If there is a deviation in the subsequent installation, the previously installed cover plates need to be adjusted, which is a rather cumbersome process. Utility Model Content

[0006] The purpose of this utility model is to provide a prefabricated cover plate for spliced ​​pipe gallery roofs, which can effectively solve the problems in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A prefabricated cover plate for a spliced ​​pipe gallery includes a base plate, on both sides of the top of the base plate, and a number of cover plates one and cover plates two are provided on the top of the masonry walls.

[0009] The first cover plate has slots on both sides, and the second cover plate has blocks that are fixedly connected to both sides to match the slots. Each second cover plate can be detachably installed on the inner side of the two cover plates through the blocks and slots. A rubber sealing block is provided at the connection between the slots and the blocks.

[0010] Preferably, the top surfaces of the first cover plate and the second cover plate are provided with a waterproof layer, which is made of polyester felt base material.

[0011] Preferably, a thick tar paper is provided at the top of the masonry wall, the tar paper is one centimeter thick, and the top surface of the thick tar paper is in contact with the bottom surface of the cover plate one and the cover plate two.

[0012] Preferably, positioning blocks are fixedly connected to the bottom surfaces of both the first and second cover plates at their front and rear ends, and the sides of the two positioning blocks that are far apart from each other are in contact with the inner wall of the masonry wall.

[0013] Preferably, the top surfaces of the cover plate one and the cover plate two are on the same horizontal plane, and the top surface of the waterproof layer after several cover plates one and cover plates two are spliced ​​together is provided with the same piece of polymer modified bitumen waterproof membrane.

[0014] Preferably, both the first cover plate and the second cover plate are provided with a number of equidistant reinforcing ribs inside. The reinforcing ribs are high-strength threaded steel, and the outer ring of the reinforcing ribs is provided with anti-corrosion coating.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model uses a combination of cover plate one and cover plate two, with the cover plate two's locking block engaging with the cover plate one's locking groove to form a concave-convex fit structure. This prevents water from directly seeping in from the connection point. Furthermore, a rubber sealing block is provided at the connection point. The rubber sealing block deforms under pressure, which further reduces the gaps in the connection and lowers the probability of water leakage.

[0017] By using positioning blocks, slots, and locking blocks in coordination, multiple cover plates (one and two) can be positioned and installed during splicing, eliminating the need for installation based on experience and preventing misalignment. This also reduces the steps required for subsequent adjustments. After splicing, multiple cover plates (one and two) engage with the locking blocks through the slots and are secured within the masonry wall by the positioning blocks, improving installation stability and reducing the probability of the base plate and masonry wall being pushed to the side.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Combination Figures 1-3 A prefabricated cover plate for a spliced ​​pipe gallery roof includes a base plate 1. Masonry walls 2 are fixedly connected to both sides of the top of the base plate 1. Several cover plates 3 and cover plates 4 are provided on the top of the masonry walls 2.

[0025] See Figure 2 Furthermore, it is found that the two sides of the cover plate 3 are provided with slots 5, and the two sides of the cover plate 4 are fixedly connected with the slots 5 and the slots 6 are adapted to match the slots 5. Each cover plate 4 is detachably installed on one side of the two cover plates 3 through the slots 5 and the slots 6. A rubber sealing block 7 is provided at the connection between the slots 5 and the slots 6. A waterproof layer 9 is provided on the top surface of the cover plate 3 and the cover plate 4. The waterproof layer 9 is made of polyester felt base material. A thick tar paper 11 is provided on the top of the masonry wall 2. The thickness of the thick tar paper 11 is one centimeter, and the top surface of the thick tar paper 11 is attached to the bottom surface of the cover plate 3 and the cover plate 4. The top surfaces of the cover plate 3 and the cover plate 4 are on the same horizontal plane. After several cover plates 3 and the cover plate 4 are spliced ​​together, the top surface of the waterproof layer 9 is provided with the same piece of polymer modified bitumen waterproof membrane.

[0026] Specifically, by covering the masonry wall 2 with cover plate 3 and cover plate 4, the top surface of the masonry wall 2 can be sealed to prevent debris from falling into the masonry wall 2. Cover plate 4 is secured in the groove 5 on cover plate 3 by a locking block 6. At the same time, a rubber sealing block 7 is provided at the connection between the groove 5 and the locking block 6. The interlocking of the groove 5 and the locking block 6 can form a concave-convex structure to prevent water from flowing directly down. At the same time, the deformation and expansion of the rubber sealing block 7 at the connection can further eliminate gaps and reduce the probability of water seepage. Thus, if the polymer modified bitumen waterproof membrane installed on cover plate 4 and cover plate 3 is accidentally damaged, personnel have enough time to repair it.

[0027] Example 2

[0028] See Figure 2 and Figure 3 Furthermore, based on Embodiment 1, it is further found that positioning blocks 10 are fixedly connected to the front and rear ends of the bottom surfaces of Cover Plate 1 3 and Cover Plate 2 4. The sides of the two positioning blocks 10 that are far apart from each other are in contact with the inner wall of the masonry wall 2. Several reinforcing ribs 8 are arranged at equal intervals inside Cover Plate 1 3 and Cover Plate 2 4. The reinforcing ribs 8 are high-strength threaded steel, and the outer ring of the reinforcing ribs 8 is coated with anti-corrosion coating.

[0029] Specifically, the positioning block 10, inserted into the masonry wall 2, provides linear positioning and prevents the cover plate 3 and cover plate 4 from tilting during installation. The locking block 6, inserted into the slot 5, provides equidistant installation and prevents large gaps from requiring manual splicing of cover plate 3 and cover plate 4 without the help of personnel experience. This avoids tedious subsequent adjustment steps, improves installation efficiency and accuracy, and after several cover plates 3 and cover plate 4 are spliced, the positioning block 10 is inserted into the masonry wall 2 to improve the stability of the spliced ​​parts and prevent the cover plates 3 and cover plate 4 from being easily pushed to the side of the masonry wall 2.

[0030] In actual operation, by covering the masonry wall 2 with cover plate 3 and cover plate 4, the top surface of the masonry wall 2 can be sealed to prevent debris from falling into the masonry wall 2. Cover plate 4 is locked into the slot 5 on cover plate 3 by the locking block 6. At the same time, a rubber sealing block 7 is provided at the connection between the slot 5 and the locking block 6. The interlocking of the slot 5 and the locking block 6 can form a concave-convex structure.

[0031] To prevent water from flowing directly down, the rubber sealing block 7 is squeezed and deformed at the joint, which can further eliminate gaps and reduce the probability of water seepage. Thus, if the polymer modified bitumen waterproof membrane installed on cover plate 2 4 and cover plate 1 3 is accidentally damaged, personnel have enough time to repair it.

[0032] The positioning block 10 is inserted into the masonry wall 2 to provide a straight positioning installation and prevent the cover plate 1 3 and cover plate 2 4 from tilting during installation. The locking block 6 is inserted into the slot 5 to provide an equidistant installation and prevent large gaps.

[0033] The splicing of cover plate 3 and cover plate 4 is not based on personnel experience, so as to avoid the tedious adjustment steps later, improve the installation efficiency and accuracy, and after several cover plates 3 and cover plate 4 are spliced, they can be inserted into the masonry wall 2 by positioning block 10, which can improve the stability after splicing and prevent cover plates 3 and cover plate 4 from being easily pushed to the side of the masonry wall 2.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
