Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tunnel construction, in particular to an embedded annular crack water seepage treatment structure for an operating tunnel. Background Art
[0002] With the rapid development of highway tunnels, various diseases in operating tunnels have increased massively due to the influence of geological, topographical, climatic conditions, building materials, survey, design, construction, operation and other factors. Tunnel diseases are mainly divided into three categories: water leakage, lining structure diseases and bottom plate diseases. For different types of tunnel water leakage diseases, there are currently more mature treatment solutions for honeycomb and hole water leakage and concrete crack water leakage. Among them, lining diseases and water leakage are deeply related, so the treatment of tunnel lining water leakage has become the top priority of the treatment of operating tunnel diseases. In the long-term operation of the tunnel, the joints are prone to deformation, and tunnel water leakage often occurs in the construction joints and deformation joints in the lining.
[0003] In the related art, when the water pressure at the joint is small and the leakage pressure is small, direct water blocking measures are used. Generally, the method of drainage should be used to treat water leakage at the joint, because even if the leakage is not prevented by plugging, the joint will eventually deform due to seasonal changes and the passage of time, and the plugging material will still fall off and leak. When circumferential through cracks appear and the amount of water gushing is large, it is not appropriate to directly use water blocking measures. In addition, given the limited space in the tunnel, traditional exposed drainage grooves are easy to invade the tunnel construction limit, causing safety hazards.
[0004] In view of this, it is necessary to propose an embedded annular crack seepage treatment structure in an operating tunnel to solve the above defects. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides an embedded annular crack water seepage treatment structure in an operating tunnel, which is installed at the annular cracks of the lining, and includes a drainage groove, a filling block, and a waterproof coating.

[0016] The embedded annular crack water seepage treatment structure in the operating tunnel provided by the utility model installs the drainage groove at the annular crack of the lining, so that the seepage from the annular crack can be drained into the drainage groove and then discharged to the tunnel ditch. The filling block is filled in the gap between the drainage groove and the lining to play a role of sealing and blocking water. The waterproof coating is coated on the outer surface of the lining to ensure that the annular crack water seepage treatment of the lining is effectively water-stopped for a long time, and the lining surface is smooth and beautiful after treatment. Therefore, the treatment structure eradicates the water seepage disease and eliminates the consequences of water seepage, which in serious cases will cause slippery and icy roads, cracking and falling of the lining, and insufficient bearing capacity, thereby ensuring the safety of traffic in the operating tunnel.

[0026] Please refer to Figure 1 and Figure 2 The utility model provides an embedded annular crack water seepage treatment structure for an operating tunnel, which is installed at the annular cracks of the lining 10 in the tunnel. Figure 1 This is a structural diagram of the embedded annular crack seepage treatment structure in the operating tunnel applied to the annular cracks of the rectangular section. Figure 2This is a structural diagram of the embedded annular crack seepage treatment structure used in the annular cracks of the arch section of the operating tunnel.
[0027] See also Figure 3 The embedded annular crack water seepage treatment structure 100 of the operating tunnel includes a drainage groove 1, a filling block 3, and a waterproof coating 7. An installation groove is opened at the annular crack of the lining 10, and the drainage groove 1 is embedded in the installation groove and is located under the annular crack. The filling block 3 is filled in the gap between the two ends of the drainage groove 1 and the lining 10, and the waterproof coating 7 is coated on the surface of the lining 10 and the filling block 3. By installing the drainage groove 1 at the annular crack of the lining 10 and fixing it with the fixing member 5, the seepage from the annular crack can be drained into the drainage groove 1 and then discharged to the tunnel ditch. The filling block 3 is filled in the gap between the drainage groove 1 and the lining 10 to play a role in sealing and blocking water. The waterproof coating 7 is coated on the outer surface of the lining 10 to ensure that the annular crack water seepage treatment of the lining 10 is effectively water-stopped for a long time, and the surface of the lining 10 is smooth and beautiful after treatment. Therefore, the treatment structure eradicates the seepage disease and eliminates the consequences of seepage, which in serious cases will cause slippery and icy road surface and lining 10 cracking, falling off, insufficient bearing capacity, etc., ensuring the safety of traffic in the operating tunnel.
[0028] Specifically, in this embodiment, the middle of the drainage trough 1 is sunken downward to form a drainage channel 11, and the two wings of the drainage trough 1 extend horizontally to form a mounting portion 13, and the fixing member 5 passes through the mounting portion 13 to fix the drainage trough 1 on the lining 10. The drainage channel 11 is directly opposite to the annular crack. Figure 3 As shown, a crack is formed in the middle of the lining 10, and the drainage ditch 1 is located at the crack. The seepage from the annular crack enters the drainage channel 11. The drainage channel 11 is connected to the tunnel ditch to drain the seepage to the outside. The fixing member 5 fixes the drainage ditch 1 in the concrete of the lining 10 to strengthen the connection stability between the drainage ditch 1 and the lining 10.
[0029] Furthermore, the width of the drainage groove 1 is greater than or equal to 160 mm, the width of the mounting portion 13 is greater than or equal to 50 mm, and the thickness of the drainage groove 1 is greater than or equal to 1.5 mm, so as to ensure the basic stability of the structure.
[0030] Specifically, the drain trough 1 is a stainless steel drain trough. The stainless steel material can ensure that the drain trough 1 does not rust, reduce the corrosion of the seepage water to the drain trough 1, and extend the service life.
[0031] Specifically, in this embodiment, the filling block 3 is a sealant. Preferably, the filling block 3 is a polysulfide sealant. It should be explained that the polysulfide sealant has the properties of self-adhesion, non-flow at high temperature, and non-hardening at low temperature, thereby ensuring the sealing performance of the drainage trough 1 after construction.
[0032] Specifically, in this embodiment, the fixing member 5 is an expansion bolt, which ensures that the stainless steel drainage trough 1 is firmly connected to the concrete.
[0033] Furthermore, the annular spacing of the fixing members 5 is 10 to 20 cm.
[0034] Specifically, in this embodiment, the waterproof coating 7 is made of cement-based penetrating crystalline waterproof coating.
[0035] The utility model provides an embedded annular crack water seepage treatment structure for an operating tunnel. By installing the drainage ditch 1 at the annular crack of the lining and fixing it with the fixing member 5, the water seepage from the annular crack can be drained into the drainage ditch 1 and then discharged into the tunnel ditch. The filling block 3 is filled in the gap between the drainage ditch 1 and the lining 10 to seal and block water. The waterproof coating 7 is coated on the outer surface of the lining to ensure that the annular crack water seepage treatment of the lining is effectively water-stopped for a long time. After treatment, the lining surface is smooth and beautiful. Therefore, the treatment structure eradicates the water seepage disease and eliminates the consequences of water seepage, which in serious cases will cause slippery and icy roads, cracking and falling of the lining, and insufficient bearing capacity, thereby ensuring the safety of traffic in the operating tunnel.
