Description

Technical Field

[0001] This utility model belongs to the technical field of prefabricated segmental protective components, specifically relating to a device for repairing and reinforcing tunnel leakage and blockage. Background Technology

[0002] Existing tunnel leakage remediation solutions mostly employ grouting for sealing. However, because the location where water enters the tunnel's waterproofing structure is unclear, leaks often reappear after sealing in one area, leading to repeated remediation efforts and poor results. Localized rockfalls in the tunnel are addressed through partial chiseling, but over time, new risk points can form in areas prone to rockfalls. These risks are often hidden and difficult to detect, requiring significant manpower for inspection. For sections with localized cracks or insufficient strength or thickness, a lining solution is used. This involves pouring a layer of secondary lining concrete inside the existing tunnel using formwork to strengthen the secondary lining. However, since the tunnel is already in operation, this interferes with the remediation work, resulting in a long construction period, high construction risks, and significant impact on line operation. Summary of the Invention

[0003] This utility model is proposed to solve the problems existing in the prior art, and its purpose is to provide a device for the treatment and reinforcement of tunnel leakage and rockfall.

[0004] The technical solution of this utility model is: a device for repairing and reinforcing leaking and slab falling in tunnels, including a load-bearing beam base as the installation foundation. The load-bearing beam base is installed on the outer side of the existing tunnel floor in the transverse direction. An annular load-bearing beam with an overall ring shape is provided on the load-bearing beam base. The outer contour of the annular load-bearing beam is adapted to the inner contour of the tunnel secondary lining and supports and reinforces it. A guide channel steel plate is provided between adjacent annular load-bearing beams. The groove of the guide channel steel plate faces the tunnel secondary lining and guides the leaking water in the tunnel.

[0005] Furthermore, the guide channel of the guide plate and the secondary lining of the tunnel form a guide channel, and a diversion pipe is provided in the load-bearing beam base, with the upper end of the diversion pipe connected to the guide channel.

[0006] Furthermore, the lower end of the drainage pipe is connected to the tunnel side ditch in the tunnel, draining the leaking water from the tunnel into the tunnel side ditch.

[0007] Furthermore, the guide channel steel plate extends laterally at the opening to form an installation wing plate. One side of the installation wing plate is in contact with the secondary lining of the tunnel, and the other side of the installation wing plate is supported by an annular load-bearing beam assembled into a ring.

[0008] Furthermore, a sealing strip is provided on the side of the mounting wing plate facing the tunnel secondary lining, and the sealing strip seals the flow channel.

[0009] Furthermore, the annular load-bearing beam comprises multiple load-bearing beam units, which are assembled and fixed together by load-bearing beam splicing plates.

[0010] Furthermore, the guide channel steel plate is an assembled structure, and a guide channel socket is provided at the lower end of the assembled side of the guide channel steel plate, which is connected to the adjacent guide channel steel plate.

[0011] Furthermore, the insertion port of the flow guide groove is adapted to the flow guide groove, thereby preventing water leakage at the assembly connection.

[0012] This invention can quickly eliminate the impact of water leakage in the secondary lining of the tunnel on the operating equipment inside the tunnel, prevent localized rockfalls from hitting the operating equipment inside the tunnel, and at the same time, it can reinforce the localized cracks and thickness defects of the secondary lining, eliminating the adverse effects of insufficient bearing capacity of the secondary lining on operational safety.

[0013] This invention improves the treatment effect and construction speed of tunnel leakage and spalling defects, reduces the risk to railway operation safety caused by local cracking or insufficient strength and thickness of secondary tunnel lining, and overall reduces the cost of treating similar defects, improves the efficiency of defect treatment, and reduces the safety risks of tunnel defect treatment construction.

[0028] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0029] like Figures 1 to 6 As shown, a tunnel leakage and spalling repair and reinforcement device includes a load-bearing beam base 5 as the installation foundation. The load-bearing beam base 5 is installed on the outer side of the existing tunnel floor in the transverse direction. An annular load-bearing beam 4, which is circular in shape, is provided on the load-bearing beam base 5. The outer contour of the annular load-bearing beam 4 is adapted to the inner contour of the tunnel secondary lining 1 and supports and reinforces it. A guide channel steel plate 3 is provided between adjacent annular load-bearing beams 4. The groove of the guide channel steel plate 3 faces the tunnel secondary lining 1 and guides the leakage of tunnel water.

[0030] The guide channel 2 of the guide channel steel plate 3 and the tunnel secondary lining 1 form a guide channel. The load-bearing beam base 5 is provided with a diversion pipe 7, and the upper end of the diversion pipe 7 is connected to the guide channel.

[0031] The lower end of the drainage pipe 7 is connected to the tunnel side ditch 8 in the tunnel, so that the leaking water in the tunnel is discharged into the tunnel side ditch 8.

[0032] The guide channel steel plate 3 extends laterally at the opening to form an installation wing plate. One side of the installation wing plate is in contact with the secondary lining 1 of the tunnel, and the other side of the installation wing plate is supported by an annular load-bearing beam 4 assembled into a ring.

[0033] A sealing strip 6 is provided on the side of the mounting wing plate facing the secondary lining 1 of the tunnel, and the sealing strip 6 seals the flow channel.

[0034] The annular load-bearing beam 4 comprises multiple load-bearing beam units, which are assembled and fixed together by load-bearing beam splicing plates 41.

[0035] The guide channel steel plate 3 is an assembled structure. The lower end of the assembled side of the guide channel steel plate 3 is provided with a guide channel socket 31, which is connected to the adjacent guide channel steel plate 3.

[0036] The guide channel socket 31 is adapted to the guide channel 2, thereby preventing water leakage at the assembly connection.

[0037] Specifically, the load-bearing beam base 5 is fixed to the tunnel floor slab by anchoring, and the load-bearing beam base 5 serves as the installation foundation for the annular load-bearing beam 4.

[0038] Specifically, the load-bearing beam base 5 is connected to the annular load-bearing beam 4 through the base height adjustment assembly 51. Flanges are formed in alignment between the load-bearing beam base 5 and the annular load-bearing beam 4. The base height adjustment assembly 51 is a bolt and nut assembly. The bolts pass through the two flanges. Each bolt has four nuts. The four nuts are fixed in pairs on both sides of the flange, thereby adjusting the position of the load-bearing beam base 5 and the annular load-bearing beam 4.

[0039] Specifically, such as Figure 3 As shown, the guide channel steel plate 3 is fixed to the inner side of the tunnel secondary lining 1 by two ring-shaped load-bearing beams 4.

[0040] Specifically, the load-bearing beam unit of the annular load-bearing beam 4 is an I-shaped structure with a through hole formed in its web for connection. A load-bearing beam splicing plate 41 is provided between adjacent webs to connect the two. The load-bearing beam splicing plate 41 has a through hole formed in its alignment. The load-bearing beam splicing bolt 42 passes through the load-bearing beam splicing plate 41 and the web of the load-bearing beam unit and is then fixed by screwing on a nut.

[0041] Specifically, the sealing strip 6 at the mounting wing plate may be, but is not limited to, one strip.

[0042] As one implementation method, a splicing guide channel 32 can also be provided between adjacent guide channel steel plates 3. The splicing guide channel 32 also forms a guide channel 2 facing the tunnel secondary lining 1. The splicing guide channel 32 can connect the adjacent guide channel steel plates 3 into a whole.

[0043] Specifically, the splicing guide channel 32 and the guide channel steel plate 3 are fixed by bolts and nuts.

[0044] Specifically, the diversion channel 2 is used to guide the seepage water from the tunnel arch wall to the tunnel side ditch 8, while also preventing it from covering the tunnel secondary lining 1 and causing it to fall and hit trains and other operating equipment; the annular load-bearing beam 4 is used to support the steel plate 3 of the diversion channel, and at the same time provides support for the tunnel arch wall, thus reinforcing the tunnel arch wall; the load-bearing beam base 5 is the overall installation foundation, transferring the load borne by the annular load-bearing beam 4 to the tunnel floor; the sealing strip 6 makes the diversion channel 5 a sealed diversion channel, preventing side leakage and affecting various operating equipment in the tunnel.

[0045] Specifically, when using the splicing method, a guide channel 2 is installed on the lower edge of the adjacent annular load-bearing beam 4 to guide the leakage between the two devices and prevent the block from hitting the operating equipment inside the tunnel.

[0046] Specifically, the guide channel steel plate 3, the annular load-bearing beam 4, and the load-bearing beam base 5 are all made of weathering steel to ensure that their service life meets the needs of tunnel operation.

[0047] This invention can quickly eliminate the impact of water leakage in the secondary lining of the tunnel on the operating equipment inside the tunnel, prevent localized rockfalls from hitting the operating equipment inside the tunnel, and at the same time, it can reinforce the localized cracks and thickness defects of the secondary lining, eliminating the adverse effects of insufficient bearing capacity of the secondary lining on operational safety.

[0048] This invention improves the treatment effect and construction speed of tunnel leakage and spalling defects, reduces the risk to railway operation safety caused by local cracking or insufficient strength and thickness of secondary tunnel lining, and overall reduces the cost of treating similar defects, improves the efficiency of defect treatment, and reduces the safety risks of tunnel defect treatment construction.
