Description

Technical Field

[0001] This utility model relates to the field of waterproofing technology for municipal utility tunnel construction, specifically a waterproofing system for a composite flow-guiding and locking structure in municipal utility tunnels. Background Technology

[0002] In existing municipal utility tunnel construction projects, waterproof membranes often leak due to improper joint treatment, affecting structural safety and service life. Traditional materials lack effective flow guidance and edge-locking mechanisms, making them unsuitable for complex underground environments. Therefore, there is an urgent need for a composite flow-guiding and edge-locking waterproofing system for municipal utility tunnels to overcome these problems. Utility Model Content

[0003] The purpose of this utility model is to provide a waterproof system for a composite flow-guiding and locking structure in municipal utility tunnels, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A composite flow-guiding and edge-locking waterproofing system for municipal utility tunnels includes a waterproof membrane composed of an adhesive interface, an asphalt base layer, and a woven surface layer. The membrane has rounded ends in the width direction. One end of the waterproof membrane is configured as an overlapping section for connecting to the lower waterproof membrane. The asphalt base layer at the overlapping section also includes a flow-guiding groove and water-locking beads. The flow-guiding groove is a hollow groove structure. The area outside the flow-guiding groove and inside the edge of the overlapping membrane is used for bonding the overlapping membrane and the lower waterproof membrane. The water-locking beads are beaded chain structures located inside the flow-guiding groove, with each bead being a flattened sphere.

[0006] As a further embodiment of this invention: the bonding interface is located at the bottom layer of the waterproof membrane and is made of adhesive.

[0007] As a further embodiment of this utility model: the asphalt base layer is a roll-shaped waterproof base layer material made by mixing asbestos fiber and rubber powder into asphalt material and then rolling it.

[0008] As a further embodiment of this utility model: the water-locking beads are filled with natural sodium-based bentonite particles and corresponding additives, and mixed evenly to form a water-locking material.

[0009] As a further embodiment of this utility model, it also includes a drainage system connected to the waterproofing system. The drainage system includes a guide pipe, a check valve, a collection well, a water pump, and a drain pipe. The guide pipe is used to collect the groundwater that seeps into the guide channel and discharge it into the collection well connected to the guide pipe. The check valve is installed on the guide pipe, and the distance between two adjacent check valves is 1 to 3 times the width of the waterproof membrane. The water pump is installed at the bottom of the collection well and is used to pump the groundwater collected in the collection well and discharge it to the ground through the drain pipe.

[0010] Compared with existing technologies, the beneficial effects of this utility model are as follows: By introducing a composite flow-guiding and locking edge structure, it effectively guides the drainage of infiltrated water, while simultaneously sealing the path of groundwater seeping into the pipe gallery, enhancing joint sealing, significantly improving the waterproof performance of the system, extending the service life of the pipe gallery, and ensuring the safety and stability of the project. This membrane adopts a multi-layer composite design. The upper woven surface layer protects the waterproof structure of the membrane from puncture and tearing damage, increases the surface texture depth of the membrane, and enhances the bonding strength of overlapping membranes. The middle asphalt base layer isolates groundwater, and the lower bonding interface strengthens the bonding force. It adapts to various substrates, is convenient and efficient to construct, and is suitable for various municipal pipe gallery projects. The flow-guiding channel and pipe guide the drainage of groundwater seeping into the waterproof system, while the water-locking beads prevent further seepage of groundwater into the waterproof system, forming multiple layers of waterproof and seepage-proof protection. Even in extreme conditions, the membrane can maintain excellent waterproof performance, preventing groundwater infiltration and ensuring the dryness of the pipe gallery interior. The optimized rounded sides of the waterproof membrane and the absence of gaps at the overlaps enhance the structural tightness of the waterproof system. It improves the overall reliability of the waterproofing system and reduces later maintenance costs; optimizes the construction process, making the installation of the roll material simpler and improving project efficiency; and is suitable for various municipal utility tunnel projects.

[0015] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] Please see Figures 1-3This utility model provides a composite flow-guiding and edge-locking waterproof system for municipal utility tunnels. The system includes a waterproof membrane 1, which is composed of an adhesive interface 3, an asphalt base layer 4, and a woven surface layer 5. The waterproof membrane 1 has arc-shaped ends in the width direction, and there are no gaps between the overlapping sections. One end of the waterproof membrane 1 is configured as an overlapping membrane 2 for connecting to the lower waterproof membrane 1. The asphalt base layer 4 at the overlapping membrane 2 also includes a flow-guiding groove 6 and water-locking beads 7. The flow-guiding groove 6 is a hollow groove structure. After water seepage occurs at the joint between the overlapping membrane 2 and the lower waterproof membrane 1, the seeping groundwater is guided to the lower part of the overall waterproof structure of the utility tunnel and flows into the flow-guiding pipe 8. The area outside the flow-guiding groove 6 and inside the edge of the overlapping membrane 2 is used for bonding the overlapping membrane 2 and the lower waterproof membrane 1. The water-locking beads 7 are bead-like chain structures located inside the flow-guiding groove 6, and each water-locking bead 7 is a flattened sphere.

[0017] The bonding interface 3 is located at the bottom layer of the waterproof membrane 1 and is made of adhesive. The main components of the adhesive are plasticizer, tackifier, resin and thermoplasticizer. After processing, it is in a stable solid state. After heating, it is in a hot melt state and is tightly bonded to the waterproof coating of the waterproof interface. After cooling again, it maintains a tight bond with the waterproof interface.

[0018] The asphalt base layer 4 is a roll-shaped waterproof base layer material made by mixing asbestos fiber and rubber powder into asphalt material and then rolling it.

[0019] The surface layer 5 is made of reinforcing fibers woven in both the longitudinal and transverse directions. It protects the asphalt base layer 4 from puncture and damage by foreign objects, protects the asphalt base layer 4 from tensile damage, increases the surface texture depth of the asphalt base layer 4, and helps to improve the overlap adhesion of the waterproof membrane 1.

[0020] The water-locking beads 7 are filled with natural sodium-based bentonite particles and corresponding additives, and are mixed evenly to form a water-locking material. When water seepage occurs at the joint between the overlapping membrane 2 and the lower waterproof membrane 1, the water-locking beads 7 absorb the seeping groundwater. The bentonite particles swell when they come into contact with water, forming a uniform colloid. Under the constraint of the asphalt base layer 4, the bentonite expands in an orderly manner to achieve compaction, thereby preventing groundwater from further seeping into the subsequent joint and maintaining the seepage prevention function of the joint.

[0021] It also includes a drainage system connected to the waterproofing system. The drainage system includes a diversion pipe 8, a check valve 9, a collection well 10, a water pump 11, and a drain pipe 12. The diversion pipe 8 is used to collect the groundwater that seeps into the diversion channel 6 and discharge it into the collection well 10 connected to the diversion pipe 8. The check valve 9 is installed on the diversion pipe 8, and the distance between two adjacent check valves 9 should be 1 to 3 times the width of the waterproof membrane 1 to prevent the groundwater in the diversion pipe 8 from flowing back into the waterproofing system. The water pump 11 is installed at the bottom of the collection well 10 to pump the groundwater collected in the collection well 10 and discharge it through the drain pipe 12 to a place where it will not affect the ground.

[0022] The preferred embodiments of this application have been described in detail above, but this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
