Description

Technical Field

[0001] The utility model belongs to the technical field of urban utility tunnels, and particularly relates to a prefabricated assembled urban comprehensive utility tunnel. Background Art

[0002] At present, the construction of tunnel linings in China mainly adopts the integral cast-in-place method, which has problems such as high construction risks, large environmental pollution, long in-well transportation distances, and low construction efficiency. The use of prefabricated lining blocks can significantly shorten the construction period while ensuring quality. The structure of the assembled urban comprehensive utility tunnel after assembly is the same as that of the integral cast-in-place structure, greatly reducing the problems of high construction risks, large environmental pollution, and low construction efficiency. However, during the splicing process, the prefabricated lining blocks are asymmetric and there are problems with accuracy, which will make it difficult to align some brackets during the future use of the utility tunnel, and the space of the utility tunnel cannot be effectively utilized; there is also the problem of waterproofing after splicing, which is also a difficult problem that needs to be overcome. Summary of the Invention

[0003] The purpose of the utility model is to overcome the deficiencies existing in the prior art and provide a prefabricated assembled urban comprehensive utility tunnel that can greatly improve accuracy and waterproofing problems.

[0004] The purpose of the utility model is achieved by the following technical solutions. This prefabricated assembled urban comprehensive utility tunnel includes a utility tunnel, lining blocks, and load-bearing blocks. A transportation channel is poured at the bottom of the utility tunnel along the length direction. L-shaped notches are poured on both sides of the transportation channel, and the two L-shaped notches are symmetrically distributed along the center of the transportation channel; the lower end of the lining block is placed on the L-shaped notch of the transportation channel, and the lining blocks are sequentially fitted and assembled along the length direction of the utility tunnel and are symmetrically distributed along the transportation channel; the load-bearing blocks are placed on the symmetrically distributed lining blocks and are sequentially assembled and placed along the length direction of the utility tunnel to form a shape. A column is built in the center of the load-bearing block. The bottom of the column is fixed to the load-bearing block, and the top of the column is fixed to the top of the utility tunnel; brackets for placing the required components of the utility tunnel are installed on the inner wall of the utility tunnel above the load-bearing block, the inner surface of the lining block, and both sides of the column.

[0005] The beneficial effects of the utility model are as follows: Compared with the prior art, by pouring a transportation channel at the bottom of the utility tunnel and the L-shaped notches being symmetrically distributed along the center of the transportation channel, the lining blocks can be symmetrically distributed during the assembly process, and the installation accuracy is greatly improved; at the same time, by installing load-bearing blocks and columns, the space of the utility tunnel is effectively utilized.

[0006] Preferably, a shelf for placing reserved pipelines is installed between the transportation channel and the inner lining block on one side, and cement blocks are built between the transportation channel and the inner lining block on the other side. A shelf for placing water supply pipes is installed on the cement blocks. A drainage groove is poured on the transportation channel, and the drainage groove is located at the side of the cement blocks. By setting up the shelf, the utilization space of the pipe gallery is further improved, and the drainage groove is set up to facilitate the drainage of the pipe gallery.

[0007] Preferably, the inner lining block includes a lining block body. An upper lining block is integrally cast at the upper end of the lining block body, and the upper lining block is of a T-shaped structure. A lower placing block is integrally cast at the lower end of the lining block body, and the lower placing block abuts against the L-shaped notch of the transportation channel. The lining block body is arc-shaped, and the outer surfaces of the lining block body and the upper lining block are both arc-shaped and coincide with the radian of the side wall of the pipe gallery. The inner surface of the upper lining block is a vertical plane, the inner surface of the lining block body is arc-shaped, and the top surface, bottom surface and the side surface abutting against the L-shaped notch of the lower placing block are all planar. Through the integral casting setting of the lining block body, the upper lining block and the lower placing block, and the upper lining block being of a T-shaped structure, adjacent inner lining blocks in the length direction of the pipe gallery can abut against each other through the upper lining blocks, so that a large gap will be left between the lining block bodies, thereby making the volume of the entire lining block body small and the weight greatly reduced.

[0008] Preferably, a layer of nitrile cork rubber layer is attached to the outer surfaces of the lining block body and the upper lining block. In this way, when the inner lining block is installed and fitted with the side wall of the pipe gallery, it will not collide hard and cause the inner lining block to break. By setting the nitrile cork rubber layer, the fitting stability after installation is better.

[0009] Preferably, an epoxy mortar layer is coated between the lower placing block and the L-shaped notch, and the upper surface of the lower placing block is flush with the upper surface of the transportation channel. By coating the epoxy mortar layer, the waterproof performance between the lower placing block and the L-shaped notch is better. At the same time, the upper surface of the lower placing block is flush with the upper surface of the transportation channel, making the spatial integrity of the pipe gallery better.

[0010] Preferably, an epoxy mortar layer is coated between the upper lining block and the load-bearing block, and the gap between adjacent upper lining blocks is injected with an epoxy mortar layer. By coating the epoxy mortar layer, the waterproof performance between the upper lining block and the load-bearing block and between adjacent upper lining blocks is better.

[0017] The following will introduce the present utility model in detail with reference to the drawings: As shown in the attached Figure 1 , 2 figures, the present utility model includes a pipe gallery 1, an inner lining block 2 and a load-bearing block 3. A transportation channel 4 is poured at the bottom of the pipe gallery 1 along the length direction.

A column 5 is built in the center of the load-bearing block 3. The bottom of the column 5 is fixed to the load-bearing block 3, and the top of the column 5 is fixed to the top of the pipe gallery 1; Bracket 6 for shelving the required items of the pipe gallery is installed on the inner wall of the pipe gallery 1 above the load-bearing block 3, the inner surface of the inner lining block 2 and both sides of the column 5. The items required for shelving the pipe gallery are cables, communication lines, high-pressure water pipes, etc.

[0018] A shelving rack 7 for shelving reserved pipes is installed between the transportation channel 4 and the inner lining block 2 on one side. A cement block 8 is built between the transportation channel 4 and the inner lining block 2 on the other side, and a shelving rack 7 for shelving the water supply pipe is installed on the cement block 8. A drainage groove 42 is poured on the transportation channel 4, and the drainage groove 42 is located at the side of the cement block 8.

[0019] The lining block 2 includes a lining block body 21. An upper lining block 22 is integrally cast at the upper end of the lining block body 21, and the upper lining block 22 has a T-shaped structure. A lower resting block 23 is integrally cast at the lower end of the lining block body 21, and the lower resting block 23 abuts against the L-shaped notch 41 of the transportation channel 4. The lining block body 21 is arc-shaped, and the outer surfaces of both the lining block body 21 and the upper lining block 22 are arc-shaped and coincide with the radian of the side wall of the pipe gallery 1. The inner surface of the upper lining block 22 is a vertical plane, the inner surface of the lining block body 21 is arc-shaped, and the top surface, bottom surface and the side surface abutting against the L-shaped notch 41 of the lower resting block 23 are all planar.

[0020] A layer of nitrile cork rubber layer 24 is coated on the outer surfaces of both the lining block body 21 and the upper lining block 22.

[0021] An epoxy mortar layer 25 is coated between the lower resting block 23 and the L-shaped notch 41, and the upper surface of the lower resting block 23 is flush with the upper surface of the transportation channel 4.

[0022] An epoxy mortar layer 25 is coated between the upper lining block 22 and the load-bearing block 3, and the gap between adjacent upper lining blocks 22 is filled with an epoxy mortar layer 25.

[0023] During the assembly process of the above-mentioned lining blocks, the existing hoisting method is to bundle prefabricated lining blocks with a sling and install them on the pipe gallery wall. This has poor safety performance during the hoisting process, and the installation is also rather troublesome. Especially after the prefabricated lining block is installed on the pipe gallery wall, it is very troublesome to untie the sling, which is time-consuming and laborious. The following structural method is adopted to solve this technical problem, as shown in the attached Figures 3 to 5 As shown in the figure, a connecting lifting piece 9 for lifting the lining block is fixed between the inner surface of the upper lining block 22 and the inner surface of the lining block body 21. The connecting lifting piece 9 is fixed between the inner surface of the upper lining block 22 and the inner surface of the lining block body 21 by an embedding method and is located at the exact center position between the upper lining block 22 and the lining block body 21, and the connecting end face of the connecting lifting piece 9 is flush with the inner surface of the lining block body 21. Through the setting of the above structure, a connecting lifting piece for lifting the lining block is fixed between the upper lining block and the lining block body, so that when hoisting the lining block, it is not necessary to bundle the prefabricated lining block with a sling and install it on the pipe gallery wall, thus making the hoisting and installation very convenient and having high safety performance. Moreover, the such structural setting of the connecting lifting piece does not affect the overall structural outer surface of the lining block, and the orientation setting of the connecting lifting piece makes the force stability more uniform when hoisting the lining block through the connecting lifting piece.

[0024] The connecting suspension member 9 includes a suspension cylinder 91 and embedding members 92. There are at least two embedding members 92, which are distributed equidistantly in a surrounding manner along the outer circumferential wall of the suspension cylinder 91. Both the suspension cylinder 91 and the embedding members 92 are embedded and integrally formed during the casting of the lining block body 21. An internal thread 93 for rotatably connecting and fixing with a lifting member is provided inside the suspension cylinder 91. Through the setting of the above structure, the forming of the connecting suspension member is more convenient. At the same time, through the setting of the embedding members, the force on the suspension cylinder on the inner lining block is better, and an internal thread is provided inside the suspension cylinder, making the connection with external lifting tools more convenient during the connection process.

[0025] The bottom of the suspension cylinder 91 is a closed structure, and the upper end surface of the upper part is flush with the inner surface of the lining block body 21. The bottom is set as a closed structure, so that when the suspension cylinder is buried in the inner lining block and integrally cast, it can prevent the concrete slurry from entering the suspension cylinder. Through the flush upper end surfaces between the two, the outer surface of the inner lining block is not affected.

[0026] The embedding members 92 are steel bars, and the upper parts of the embedding members 92 are fixed to the outer circumferential wall of the suspension cylinder 91 by welding. The lower parts of the embedding members 92 are bent and bent along the outer side direction of the suspension cylinder 91. Through the setting of the above structure, the anti-pulling force of the embedding members in the inner lining block is better, so that the stability of the entire connecting suspension member is better during the lifting process after being connected with an external lifting tool.

[0027] The forming process of the present utility model is as follows: First, four embedding members 92 are provided and fixed to the outer circumferential wall of the suspension cylinder 91 equidistantly by welding, and the lower parts of the embedding members 92 protrude downward from the bottom of the suspension cylinder 91; then, the connecting suspension member 9 is placed in a casting mold to integrally cast and form the inner lining block; finally, the cured inner lining block is threadedly rotatably connected and fixed with an external lifting tool through the internal thread 93 of the suspension cylinder 91, and is lifted and installed on the side wall of the pipe gallery 1 by a multi-joint robot, and a load-bearing block 3 is placed on the inner lining block 2, a column 5 is erected on the load-bearing block, and brackets 6 are installed on the inner wall of the pipe gallery 1 above the load-bearing block 3, the inner surface of the inner lining block 2, and both sides of the column 5.

[0028] The above is only the specific implementation manner of this application, but the protection scope of this application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed in this application should be covered within the protection scope of this application. Therefore, the protection scope of this application should be subject to the protection scope of the claims.
