Description

Technical Field

[0001] This utility model relates to the field of tunnel structure technology, specifically a structural reinforcement and waterproofing structure for a brick-walled concrete roof tunnel. Background Technology

[0002] A tunnel is an engineering structure buried underground, representing a form of human utilization of underground space. Tunnels can be categorized into traffic tunnels, hydraulic tunnels, municipal tunnels, mining tunnels, and military tunnels. The structure of a tunnel consists of two parts: the main building and auxiliary equipment. The main building comprises the tunnel body and portals, while auxiliary equipment includes passing bays, fire-fighting facilities, emergency communication systems, and drainage systems. Longer tunnels also have specialized ventilation and lighting equipment. Based on geological conditions, tunnels can be classified as soil tunnels or rock tunnels. According to length, tunnels can be divided into short tunnels (railway tunnels: L≤500m; highway tunnels: L≤500m) and medium-length tunnels (railway tunnels: 500>m).

[0003] However, the internal wall reinforcement during tunnel construction is currently insufficient, resulting in unstable internal tunnel structure and a tendency for soil and rock to fall or collapse within the tunnel walls. Therefore, this utility model provides a structural reinforcement and waterproofing structure for tunnels with brick sidewalls and concrete roofs to meet people's needs. Utility Model Content

[0004] This utility model provides a structural reinforcement and waterproofing structure for a brick-walled concrete roof tunnel, which can effectively solve the problem mentioned in the background art that insufficient reinforcement of the inner wall during tunnel construction leads to instability of the tunnel's internal structure and makes it prone to soil and rock falling or collapse of the tunnel's inner wall.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a structural reinforcement and waterproofing structure for a brick-sidewalled concrete roof tunnel, comprising a tunnel body, wherein an inner wall reinforcement mechanism is provided on the inner wall of the tunnel body;

[0006] The inner wall reinforcement mechanism includes an annular reinforcing steel plate, mounting through holes, a tightly fitting long plate, a reinforcing long rod, locking bolts, grooves, splicing gaps, an annular protective steel plate, and limiting protrusions;

The annular reinforcing steel plate has equidistant mounting holes in the middle along the circumferential direction. The inner wall of the annular reinforcing steel plate is fitted with a close-fitting long plate in the circumferential direction. The close-fitting long plate has a reinforcing long rod installed through it at equidistant intervals in the middle. The end of the reinforcing long rod is fitted with a locking bolt. The middle of the close-fitting long plate and the corresponding position of the reinforcing long rod are both provided with grooves.

[0008] A splicing gap is left between two adjacent closely fitting long plates. An annular protective steel plate is installed on the inner side of the annular reinforcing steel plate. Limiting protrusions are fixedly connected at equal intervals along the circumferential direction on the surface wall of the annular protective steel plate.

[0009] Preferably, the reinforcing rod extends through the mounting hole and is inserted into the interior of the tunnel body, and the locking bolt is embedded in the groove.

[0010] Preferably, the outer wall of the annular protective steel plate is in contact with the surface of the long plate, and the limiting protrusion is movably embedded inside the splicing gap.

[0011] Preferably, the tunnel body is equipped with a waterproof diversion mechanism inside;

[0012] The waterproof diversion mechanism includes a waterproof pouring layer, a waterproof steel plate, a diversion channel, a crushed stone drainage layer, a drainage channel, a splicing notch, a shielding steel plate, drainage holes, and a support column;

[0013] The tunnel body has a waterproof pouring layer inside, and a waterproof steel plate is installed on the inner wall of the waterproof pouring layer. A diversion channel is symmetrically installed at the bottom of the tunnel body. A crushed stone drainage layer is embedded in the diversion channel.

[0016] Preferably, one end of the shielding steel plate is in close contact with the gravel drainage layer, and one end of the support column is in contact with the shielding steel plate.

[0017] Compared with the prior art, the advantages of this utility model are: the structure of this utility model is scientific and reasonable, and it is safe and convenient to use.

[0018] 1. An internal wall reinforcement mechanism is installed, which uses annular reinforcing steel plates and reinforcing long rods to support and stabilize the inner wall of the tunnel, improving the overall structural stability of the tunnel and preventing the inner wall from collapsing or rocks from falling. The reinforcing long rods and the adjacent long plates are locked and fixed with locking bolts, making the installation simple.

[0030] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0031] Example: Figure 1-4 As shown, this utility model provides a technical solution: a structural reinforcement and waterproofing structure for a brick-sidewalled concrete roof tunnel, including a tunnel body 1, and an inner wall reinforcement mechanism 2 is provided on the inner wall of the tunnel body 1.

[0032] The inner wall reinforcement mechanism 2 includes an annular reinforcement steel plate 201, a mounting through hole 202, a close-fitting long plate 203, a reinforcement long rod 204, a locking bolt 205, a groove 206, a splicing gap 207, an annular protective steel plate 208, and a limiting protrusion 209.

[0033] An annular reinforcing steel plate 201 is fitted to the inner wall of the tunnel body 1. An installation through hole 202 is equidistantly opened in the middle of the annular reinforcing steel plate 201 along the circumferential direction. A close-fitting long plate 203 is fitted to the inner wall of the annular reinforcing steel plate 201 along the circumferential direction. A reinforcing long rod 204 is equidistantly installed through the middle of the close-fitting long plate 203. A locking bolt 205 is installed at the end of the reinforcing long rod 204. A groove 206 is opened at the corresponding position of the close-fitting long plate 203 and the reinforcing long rod 204. The reinforcing long rod 204 is movably inserted through the installation through hole 202 and inserted into the interior of the tunnel body 1. The locking bolt 205 is embedded in the interior of the groove 206.

[0034] A splicing gap 207 is left between two adjacent, closely attached long plates 203. An annular protective steel plate 208 is installed on the inner side of the annular reinforcing steel plate 201. Limiting protrusions 209 are fixedly connected at equal intervals along the circumferential direction on the surface wall of the annular protective steel plate 208. The surface wall of the annular protective steel plate 208 is in contact with the surface of the closely attached long plate 203. The limiting protrusions 209 are movably embedded into the interior of the splicing gap 207. The annular reinforcing steel plate 201 and the reinforcing long rod 204 work together to support and stabilize the inner wall of the tunnel, thereby improving the overall structural stability of the tunnel. To prevent the tunnel wall from collapsing or rocks from falling, the reinforcing rod 204 and the close-fitting plate 203 are locked and fixed using locking bolts 205. The installation method is simple. At the same time, the close-fitting plate 203 and the locking bolts 205 are covered and protected by the annular protective steel plate 208, making the tunnel wall smooth and integrated. The limiting protrusion 209 positions the annular protective steel plate 208 to prevent it from shaking and shifting. The annular protective steel plate 208 and the annular reinforcing steel plate 201 work together to achieve double isolation protection and improve the safety of the tunnel.

[0035] The tunnel body 1 is equipped with a waterproof diversion mechanism 3 inside;

[0036] The waterproof diversion mechanism 3 includes a waterproof pouring layer 301, a waterproof steel plate 302, a diversion channel 303, a crushed stone drainage layer 304, a drainage channel 305, a splicing notch 306, a shielding steel plate 307, a drainage hole 308, and a support column 309.

[0037] The interior of the tunnel body 1 is provided with a waterproof pouring layer 301. A waterproof steel plate 302 is attached to the inner wall of the waterproof pouring layer 301. A diversion channel 303 is symmetrically installed at the bottom of the interior of the tunnel body 1. The two diversion channels 303 correspond to the two ends of the bottom of the waterproof pouring layer 301 and the waterproof steel plate 302, respectively. The top of the diversion channel 303 is attached to the top of the waterproof pouring layer 301 and the waterproof steel plate 302. A crushed stone drainage layer 304 is embedded in the interior of the diversion channel 303. A drainage channel 305 is fixedly installed at the bottom of the interior of the tunnel body 1 on one side of the two diversion channels 303. A splicing notch 306 is opened at one end of the drainage channel 305.

[0038] A shielding steel plate 307 is embedded inside the splicing gap 306. Drainage holes 308 are equidistantly opened in the middle of the shielding steel plate 307. Support columns 309 are equidistantly installed inside the drainage channel 305. The shielding steel plate 307 is close to one end of the crushed stone drainage layer 304. One end of the support column 309 is close to the shielding steel plate 307. The waterproof pouring layer 301 and the waterproof steel plate 302 are embedded around the tunnel, which plays a waterproof role and prevents water from seeping into the tunnel and causing damage and collapse. At the same time, the diversion channel 303 and the drainage channel 305 are used to divert and discharge the seeping water, so that the water flow is gathered and discharged outward. The crushed stone drainage layer 304 plays a role in intercepting the soil and rocks in the tunnel and preventing the water flow from carrying away the soil and rocks.

[0039] The shielding steel plate 307 intercepts the crushed stone drainage layer 304, preventing the crushed stone from being washed away and causing instability inside the tunnel. Meanwhile, the support column 309 provides support and stability to the shielding steel plate 307, making its connection with the drainage ditch 305 stronger and improving the stability of the shielding steel plate 307.

[0040] The working principle and usage process of this utility model are as follows: First, the annular reinforcing steel plate 201 is tightly attached to the inner wall of the tunnel to support and stabilize the inner wall. Then, the long plate 203 is equidistantly attached to the inner wall of the annular reinforcing steel plate 201. The reinforcing long rod 204 passes through the long plate 203 and the installation through hole 202 in sequence and is inserted into the tunnel, which reinforces the inner wall of the tunnel and improves the stability of the annular reinforcing steel plate 201. The end of the reinforcing long rod 204 is fixed by the locking bolt 205, and the locking bolt 205 is embedded in the groove 206, so that the surface of the long plate 203 is flat. The surface of the annular protective steel plate 208 is attached to the surface of the long plate 203, and the limiting protrusion 209 is embedded in the splicing gap 207, so that the annular protective steel plate 208 is positioned and supported to prevent it from shaking. At this time, the inner wall of the tunnel is flat and more neat.

[0041] The waterproof pouring layer 301 is made of concrete and embedded inside the tunnel. The waterproof steel plate 302 is tightly attached to the inner wall of the waterproof pouring layer 301, providing double waterproofing. It guides the water seeping into the tunnel soil, allowing it to flow downwards along the waterproof pouring layer 301 or the waterproof steel plate 302 and into the diversion channel 303. The gravel drainage layer 304 filters the water flow and intercepts the tunnel soil to prevent soil loss. The shielding steel plate 307 covers the splicing gap 306 and is tightly attached to the gravel drainage layer 304 to prevent the gravel drainage layer 304 from being washed away by the water flow. After being filtered, the water flows through the drainage hole 308 in the middle of the shielding steel plate 307 and flows outwards along the drainage channel 305. The support column 309 supports and stabilizes the shielding steel plate 307 to prevent it from tilting or falling over.

[0042] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
