Description

Technical Field

[0001] This utility model relates to a cold joint waterproof structure for underground engineering construction, belonging to the field of underground engineering construction technology. Background Technology

[0002] Underground engineering refers to various civil engineering facilities built deep below the ground to develop and utilize underground space resources. It covers multiple fields such as transportation, municipal administration, energy, disaster prevention, and commerce, and is an important part of modern urban construction and development.

[0003] After the completion of underground projects, multiple construction joints will be formed. If these construction joints are exposed to the outside for a long time, water seepage will occur, affecting the stability of the entire concrete. Therefore, waterproofing treatment is carried out on the construction joints. However, the commonly used waterproofing treatment is caulking. This treatment method has poor waterproofing effect and will fall off after long-term use, causing water seepage to still occur in the construction joints.

[0004] Therefore, there is an urgent need to improve the cold joint waterproofing structure for underground engineering construction in order to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of this utility model is to provide a cold joint waterproof structure for underground engineering construction. By setting up a waterproof treatment structure, the traditional caulking method is replaced to waterproof the construction joint. The addition of a sealing waterproof frame, a waterproof concrete layer and an expansion waterstop in the construction joint can achieve multi-layer waterproofing. At the same time, the structure has strong durability and will not fall off or crack after long-term use, thereby preventing water from seeping into the construction joint and helping to extend the service life of the wall.

[0006] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0007] A cold-joint waterproofing structure for underground engineering construction includes a wall and a construction joint. The wall is provided with a waterproofing treatment structure, which includes a filling groove formed on the wall. A sealing waterproof frame is fixedly installed inside the filling groove. The sealing waterproof frame is filled with a waterproof concrete layer. An expansion stop is installed on top of the waterproof concrete layer.

[0008] Preferably, a rubber sealing strip is fixedly installed on the outer side of the sealing and waterproof frame, multiple waterproof grooves are opened on the filling groove, and multiple rubber sealing strips are fixedly installed on both sides of the rubber sealing strip.

[0009] Preferably, a rubber sealing strip is fixedly installed on the outer side of the sealing and waterproof frame, multiple waterproof grooves are opened on the filling groove, and multiple rubber sealing strips are fixedly installed on both sides of the rubber sealing strip.

[0010] Preferably, the inner wall of the sealed waterproof frame is provided with multiple mounting grooves, and mounting strips extending into the mounting grooves are fixedly installed on both sides of the expansion waterstop.

[0011] Preferably, a waterproof baffle is fixedly installed on the top of the sealed waterproof frame, and the surface of the waterproof baffle is provided with a waterproof coating.

[0012] Preferably, the waterproof baffle can be one of polyurethane waterproof coating or sprayed polyurea waterproof coating.

[0013] Preferably, the bottom of the filling groove is convex, and the bottom of the sealing and waterproof frame is concave to match the bottom of the filling groove.

[0014] This utility model has at least the following beneficial effects:

[0015] By installing a waterproof structure, the traditional caulking method is replaced to waterproof the construction joints. Adding a sealed waterproof frame, a waterproof concrete layer, and an expansion stop strip to the construction joints can achieve multi-layer waterproofing.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-4 As shown in this embodiment, a cold joint waterproofing structure for underground engineering construction is provided.

[0024] A waterproof structure for cold joints in underground engineering construction includes a wall 1 and a construction joint 2. A waterproof treatment structure 3 is provided on the wall 1. The waterproof treatment structure 3 includes a filling groove 4 formed in the wall 1, a sealing waterproof frame 5 fixedly installed inside the filling groove 4, a waterproof concrete layer 6 filled inside the sealing waterproof frame 5, and an expansion stop 7 installed on top of the waterproof concrete layer 6. By using the waterproof treatment structure 3, the traditional caulking method is replaced for waterproofing the construction joint 2. With the addition of the sealing waterproof frame 5, the waterproof concrete layer 6, and the expansion stop 7, the construction joint 2 receives multi-layered waterproof protection, effectively blocking water. Simultaneously, the structure has strong durability and will not detach or crack after long-term use, thus preventing water from seeping into the construction joint 2 and extending the service life of the wall 1.

[0025] In this embodiment, as Figures 1-4As shown, a rubber sealing strip 8 is fixedly installed on the outer side of the sealing and waterproof frame 5, and multiple waterproof grooves 9 are opened on the filling groove 4. Multiple rubber sealing strips 10 are fixedly installed on both sides of the rubber sealing strip 8. Multiple installation grooves 11 are opened on the inner wall of the sealing and waterproof frame 5. Installation strips 12 extending into the installation grooves 11 are fixedly installed on both sides of the expansion waterstop 7. Multiple screws 13 connected to the installation strips 12 are installed on the sealing and waterproof frame 5. By setting up the rubber sealing strip 8, the waterproof groove 9, and the rubber sealing strip 10, the rubber sealing strip 8 can re-seal the connection between the waterproof frame 5 and the filling groove 4 after being set on the outside of the waterproof frame 5. At the same time, the rubber sealing strip 8 is also provided with upwardly inclined waterproof groove 9 and rubber sealing strip 10 on both sides. The inner diameter of the waterproof groove 9 is adapted to the outer diameter of the rubber sealing strip 10, so that the waterproof groove 9 and the rubber sealing strip 10 can form a tight connection and are inclined upward, making it difficult for water to continue to fall. Therefore, it can prevent water from penetrating downward again and further improve the waterproof effect. By setting up the installation groove 11, the installation strip 12, and the screws 13, multiple screws 13 are used to fix the expansion waterstop 7 in the waterproof frame 5, so that the expansion waterstop 7 can be firmly installed in the waterproof frame 5 and tightly bonded to the waterproof concrete layer 6, preventing the expansion waterstop 7 from expanding and falling off.

[0026] In this embodiment, as Figures 1-4 As shown, a waterproof baffle 14 is fixedly installed on the top of the sealed waterproof frame 5. The surface of the waterproof baffle 14 is provided with a waterproof coating 15. The waterproof baffle 14 can be either a polyurethane waterproof coating or a sprayed polyurea waterproof coating. The bottom of the filling groove 4 is convex, and the bottom of the sealed waterproof frame 5 is concave to match the bottom of the filling groove 4. The installation of screws 13 and waterproof baffle 14 not only protects the expansion waterstop 7 located on the outside and prevents wear, but also forms another layer of waterproof protection to prevent water from seeping into the construction joint 2. Furthermore, the waterproof baffle 14 is either a polyurethane waterproof coating or a sprayed polyurea waterproof coating, which has high strength, low temperature resistance and moisture resistance, thus improving the structural strength. By making the bottom of the filling groove 4 convex and the bottom of the sealed waterproof frame 5 concave, the bottom of the filling groove 4 is lower than the top of the construction joint 2. In this way, even if water seeps into the filling groove 4, it will converge on both sides of the bottom of the filling groove 4 and will be difficult to seep further into the construction joint 2.

[0027] In this embodiment, as Figures 1-4 As shown in this embodiment, the working process of a cold joint waterproofing structure for underground engineering construction is as follows:

[0028] After adding a sealing waterproof frame 5, a waterproof concrete layer 6, and an expansion waterstop 7 to construction joint 2, the sealing waterproof frame 5, the waterproof concrete layer 6, and the expansion waterstop 7 provide multi-layer waterproof protection for construction joint 2, effectively blocking water. At the same time, the structure has strong durability. After setting a rubber sealing strip 8 on the outside of the sealing waterproof frame 5, the connection between the sealing waterproof frame 5 and the filling groove 4 can be sealed again, preventing water from seeping downwards. After setting screws 13 and waterproof baffles 14 on the top of the sealing waterproof frame 5, the expansion waterstop 7 located on the outside is protected, preventing wear, and forming another layer of waterproof protection.

[0029] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or techniques or knowledge in related fields.
