[0002] The prefabricated components of the pipe gallery are used to support and protect various pipelines buried underground, and are convenient for inspection and maintenance of each pipeline. When installing the prefabricated components of the pipe gallery, it is necessary to first dig a pre-buried pit on the ground, and then install the prefabricated components of the pipe gallery into the pre-buried pit. During long-term use, the prefabricated components of the pipe gallery are easily damaged by external forces, causing their tops to break and collapse easily.

[0003] Since the prefabricated components of the pipeline gallery are generally integral frame structures, replacing damaged prefabricated components of the pipeline gallery requires replacing the entire structure, which is very inconvenient in operation. Utility Model Content

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] In this embodiment, refer to Figure 1-5 A prefabricated component of a pipe gallery that is easy to repair and replace includes a pipe gallery bottom component 1 and a pipe gallery top component 2. The pipe gallery top component 2 is a top cover. The pipe gallery top component 2 can be covered on the pipe gallery bottom component 1 to form an integral pipe gallery structural frame.

[0026] Specifically, a sinking groove 5 is respectively opened in the center of the upper end surface of the two arms of the bottom component 1 of the corridor, and a positioning block 6 is arranged in the sinking groove 5. The top surface of the positioning block 6 is provided with multiple wave crests 7 distributed in sequence, and wave troughs 9 are reserved between adjacent wave crests 7.

[0027] Sinking blocks 10 adapted to the sinking grooves 5 are respectively arranged on both sides of the bottom surface of the pipe gallery top component 2. The sinking blocks 10 are embedded in the corresponding sinking grooves 5 and make the butt joint surfaces of the pipe gallery bottom component 1 and the pipe gallery top component 2 fit together.

[0028] The bottom surface of the sinking block 10 is provided with a plurality of groups of sequentially spaced matching grooves 11, and the wave crests 7 below are sequentially embedded in the corresponding matching grooves 11. It should also be noted that, as shown in the attached Figure 5 As shown, the top of the crest 7 is designed as a plane, and a plurality of threaded holes 8 are opened on the plane and distributed in sequence. The positioning holes 3 are designed to have the same number of columns as the number of crests 7, and each column of positioning holes 3 above corresponds to the threaded holes 8 opened on the top surface of the crest 7 below.

[0029] When installing the top member 2 of the pipe gallery, Figure 1 or Figure 2 It can be seen that the top component 2 of the pipe gallery is provided with a positioning hole 3, and the fastening screws inserted in the positioning hole 3 are screwed downward into the threaded hole 8 at the bottom, and the bottom component 1 of the pipe gallery and the top component 2 of the pipe gallery are fixedly connected by the fastening screws.

[0030] The tunnel bottom component 1 and the tunnel top component 2 can be assembled together by tightening the screws. Here, multiple groups of wave crests 7 are designed. On the one hand, the wave crests 7 can guide the sinking of the tunnel top component 2, ensuring that the tunnel top component 2 can be accurately lowered, and finally the sinking block 10 just enters the sinking groove 5, which also provides convenience for the subsequent alignment of the positioning hole 3 and the threaded hole 8, and facilitates the tightening of the screws; on the other hand, the wave crests 7 are equivalent to a blocking effect. When water seepage occurs, multiple groups of wave crests 7 can form a flow barrier to the water body. Compared with the fitting form of the upper and lower planes, water flows infiltrate through the curved gap, and the possibility of water seepage is significantly reduced.

[0031] In this embodiment, a blunt cone end 12 is reserved between adjacent matching grooves 11, and the blunt cone end 12 is embedded in the trough 9, and the space formed between the blunt cone end 12 and the trough 9 is designed as a sealing cavity 13. The sealing holes 4 are designed to be the same number of columns as the number of troughs 9, and each column of sealing holes 4 above is downwardly connected to the sealing cavity 13. Each column of sealing holes 4 corresponds to a sealing cavity 13 below, respectively, and the top component 2 of the pipe gallery is also provided with sealing holes 4, through which sealant is injected into the sealing cavity 13. The sealing holes 4 are evenly arranged, which helps construction workers to fill the foam glue more evenly and enhance the sealing between the bottom component 1 of the pipe gallery and the top component 2 of the pipe gallery. Foam glue is injected into the sealing cavity 13 through each sealing hole 4, and when the foam glue solidifies, a secondary sealing treatment of the gap can be formed to further reduce the possibility of water seepage.

[0032] When a certain tunnel top component 2 collapses and is damaged, the staff only needs to loosen the fastening screws on the tunnel top component 2 and then replace it with a new tunnel top component 2. In this working mode, there is no need to touch the various pipelines laid on the inner wall of the tunnel prefabricated component, which makes it convenient for the staff to quickly replace or repair the damaged tunnel prefabricated component, greatly improving work efficiency.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
