Description

Technical Field

[0001] This utility model relates to the field of underground engineering technology, specifically to a water pressure balance pipe gallery in high water level areas. Background Technology

[0002] With urban development, the forms and scale of underground space development are becoming more diversified, with more and more underground utility tunnels, underground civil defense facilities, and underground roads being constructed. A common problem in underground engineering is buoyancy resistance. The impact of groundwater on underground space engineering is long-term, affecting not only structural safety but also its functionality. In particular, utility tunnel construction in areas with high groundwater levels is more susceptible to these issues.

[0003] Conventional pipe gallery anti-buoyancy measures use anti-buoyancy anchors to tie the pipe gallery to the stratum. However, the stability of the tie is related to the quality and depth of the anchor, which is always a limited tie force. This limits the anti-buoyancy of the pipe gallery and results in poor stability and practicality.

[0004] Therefore, in response to the above problems, a water pressure balance pipe gallery for high water level areas is proposed to solve these problems. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by developing a water pressure balance pipe gallery for high water level areas. This invention changes the traditional method of using a counter-buoyancy method, which can divert groundwater, reduce underground surges, avoid the impact of buoyancy, and also has pull-out resistance, resulting in better stability and practicality.

[0006] To achieve the above objectives, this utility model employs the following technical solution:

[0007] A water pressure balancing utility tunnel for high water levels includes a main tunnel body, which comprises an inner chamber and an outer wall. A drainage assembly is installed on the outer wall, comprising a drainage pipe and a leveling pipe. The leveling pipe is located inside the outer wall and connected to the drainage pipe at the bottom. The drainage pipe is inserted into the ground and connected to the aquifer. The end of the leveling pipe away from the drainage pipe is connected to a municipal drainage pipe. The drainage pipe comprises several unit pipe sections, which are connected together by a connecting assembly. A one-way locking assembly is installed on the outside of each unit pipe section for connection to the ground.

[0008] Preferably, both ends of the unit pipe section are coaxially connected to each other, and the outer diameters of the connecting pipes at both ends are the same and smaller than the outer diameter of the unit pipe section. Several convex rings are arranged circumferentially on the outer side of the connecting pipes. The convex rings are coaxially arranged with the connecting pipes, and the outer diameter of the convex rings is smaller than the outer diameter of the unit pipe section.

[0009] Preferably, a tube is coaxially provided on the outer end of the connecting pipe at one end of the unit pipe section, and a groove is coaxially provided on the inner side of the connecting pipe at the other end, with the outer diameter of the tube being the same as the diameter of the groove, for inserting the tube of the previous unit pipe section into the groove of the next unit pipe section.

[0010] Preferably, the inner diameter of the insertion tube is the same as the inner diameter of the unit tube section.

[0011] Preferably, the connecting assembly includes a connecting sleeve, which includes a left sleeve and a right sleeve. The cross-section of both the left and right sleeves is set as a semi-circular ring. The left and right sleeves are spliced ​​together to form a circular ring and connected as a whole by a fastener. Several fixing holes are opened through the opposite sidewalls of the left and right sleeves. The axes of the fixing holes are parallel to each other and perpendicular to the axis of the connecting sleeve. The fixing holes are set in a stepped shape. The diameter of the fixing holes at the ends closer to each other is smaller than the diameter at the ends farther away from each other. The fixing holes are used to install fasteners.

[0012] Preferably, the outer diameter of the connecting sleeve is the same as the outer diameter of the unit pipe section, the inner diameter of the connecting sleeve is the same as the outer diameter of the connecting pipe, and a circumferential groove is opened on the inner wall of the connecting sleeve corresponding to the convex ring for engaging with the convex ring.

[0013] Preferably, a receiving groove is formed on the outer wall of the unit pipe section to accommodate the one-way locking component, and the height of the one-way locking component when it is located in the receiving groove is not higher than the outer diameter of the unit pipe section; the one-way locking component includes a locking plate and an elastic element, one end of the locking plate is rotatably disposed on one side of the receiving groove, the other end of the locking plate is provided with a locking tooth, and the elastic element is disposed between the locking plate and the unit pipe section to push the locking plate away from the unit pipe section.

[0014] Preferably, a sealing ring one is installed between the end of the insertion tube and the bottom of the tube groove, and a sealing ring two is installed between adjacent connecting tubes.

[0015] The effects provided in the utility model description are merely those of the embodiments, and not all the effects of the utility model. The above technical solution has the following advantages:

[0016] This invention replaces the traditional anti-buoyancy method with a drainage component, which can divert water from the ground at the bottom of the utility tunnel in high-water areas to the municipal drainage network. This prevents the utility tunnel from being submerged in water and generating buoyancy due to sudden groundwater inrush, thus affecting the stability and safety of the utility tunnel. By setting a one-way locking component, the drainage component is prevented from coming off the ground under upward tension, which acts as a bolt to the utility tunnel, further improving the stability and safety of the utility tunnel against buoyancy.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figure 1-Figure 4 As shown, this utility model provides a technical solution:

[0025] A water pressure balancing utility tunnel for high-water-level areas includes a main tunnel body 1, which is constructed of cast concrete. The main tunnel body 1 includes an inner chamber 11 and an outer wall 12. The inner chamber 11 houses the pipes, preventing direct contact between the pipes and the soil layer, facilitating pipe inspection and maintenance. A drainage system is installed on the inner side of the outer wall 12 to drain groundwater. The drainage system includes a drainage pipe 2 and a leveling pipe 3, with the leveling pipe 3 integrally cast within the outer wall 12. The bottom of the horizontal water pipe 3 is connected to the drainage pipe 2. The drainage pipe 2 is inserted into the stratum and connects to the aquifer underground. The end of the horizontal water pipe 3 away from the drainage pipe 2 is connected to the municipal drainage pipe. It is used to draw water from the high water level aquifer in the stratum when the water pressure is high and drain it away into the drainage pipe. The drainage pipe 2 includes several unit pipe sections 21. The unit pipe sections 21 are connected to each other by the connecting component 4. A one-way locking component 5 is set on the outside of the unit pipe section 21 for connecting with the stratum and enhancing stability.

[0026] In this embodiment, connecting pipes 22 are coaxially arranged at both ends of the unit pipe section 21. The outer diameters of the connecting pipes 22 at both ends are the same and smaller than the outer diameter of the unit pipe section 21. Several convex rings 23 are uniformly arranged circumferentially on the outer surface of the connecting pipes 22. The cross-section of the convex rings 23 can be semi-circular or rectangular. The convex rings 23 are coaxially arranged with the connecting pipes 22, and the outer diameter of the convex rings 23 is smaller than the outer diameter of the unit pipe section 21, so as to facilitate the connection of the connecting components 4 and improve the stability of the connection.

[0027] In another embodiment, the level water pipe 3 can be a drainage pipe 2 without the one-way locking component 5, which is connected to the drainage pipe 2 with the one-way locking component 5 extending into the ground through the connecting component 4. The connection stability is better. Preferably, an ordinary water pipe with the same diameter as the unit pipe section 21 can also be used, which is connected to the drainage pipe 2 through the conventional pipe connection method to avoid water leakage, which is more economical. More preferably, a check valve is set at the end of the level water pipe 3 that is connected to the municipal pipeline to prevent water backflow and improve the practicality of the device.

[0028] In this embodiment, a tube 24 is coaxially provided at the outer end of the connecting tube 22 at one end of the unit tube segment 21, and a tube groove 25 is coaxially provided on the inner side of the connecting tube 22 at the other end. The outer diameter of the tube 24 is the same as the diameter of the tube groove 25, which is used to insert the tube 24 of the adjacent unit tube segment 21 into the tube groove 25 of the next unit tube segment 21, thereby improving the stability of the connection.

[0029] In this embodiment, the inner diameter of the insertion tube 24 is the same as the inner diameter of the unit tube section 21 to avoid the obstruction of water flow due to different inner diameters. Obstruction will slow down the water flow speed and at the same time impact the inside of the drain pipe 2, which may shorten the service life of the drain pipe 2 and improve the practicality of the device.

[0030] In this embodiment, the connecting component 4 includes a connecting sleeve 41, which includes a left sleeve 411 and a right sleeve 412. Both the left sleeve 411 and the right sleeve 412 have semi-circular cross-sections. The left sleeve 411 and the right sleeve 412 can be fitted together to form a circular ring and connected as a whole by a fastener 42, which uses screws and nuts. Several corresponding fixing holes 43 are formed through the opposite sidewalls of the left sleeve 411 and the right sleeve 412. The axes of the fixing holes 43 are parallel to each other and perpendicular to the axis of the connecting sleeve 41. The fixing holes 43 are stepped holes. The diameters of the ends closer to each other are smaller than the diameters of the ends farther apart. The fixing hole 43 is used to install the fixing member 42. The screw of the fixing member 42 passes through the corresponding adjacent fixing holes 43 on the left sleeve 411 and the right sleeve 412, and is connected to the nut at the other end. The maximum diameter of the nut and the screw head is smaller than the maximum diameter of the fixing hole 43, so that the nut and the screw head can be located in the fixing hole 43 without affecting the connection stability, and the fixing member 42 is prevented from exceeding the outer wall surface of the connecting sleeve 41 and affecting the setting of the drain pipe 2. Preferably, the insertion directions of adjacent screws and nuts are opposite, which improves the connection stability.

[0031] In this embodiment, the outer diameter of the connecting sleeve 41 is the same as the outer diameter of the unit pipe section 21, the inner diameter of the connecting sleeve 41 is the same as the outer diameter of the connecting pipe 22, and a circumferential groove 44 is opened on the inner wall of the connecting sleeve 41 corresponding to the convex ring 23 for engaging with the convex ring 23. The length of the connecting sleeve 41 is consistent with the total length of the connecting pipes 22 at both ends of the unit pipe section 21, which makes the connection more stable and stronger, and at the same time facilitates the insertion of the drainage pipe 2 into the stratum, thus improving the construction efficiency.

[0032] In this embodiment, a receiving groove 6 is provided on the outer wall of the unit pipe section 21 to accommodate the one-way locking component 5. The height of the one-way locking component 5 when it is located in the receiving groove 6 is not higher than the height of the outer wall of the unit pipe section 21 to avoid affecting the installation of the drainage pipe 2. The one-way locking component 5 includes a locking plate 51 and an elastic element 52. One end of the locking plate 51 is rotatably disposed on one side of the receiving groove 6, and the other end of the locking plate 51 is provided with a locking tooth 511 to increase the friction with the ground. The elastic element 52 can be a spring or an elastic plate and is disposed between the locking plate 51 and the unit pipe section 21 to push the locking plate 51 away from the unit pipe section 21, so that the friction between the drainage pipe 2 and the drainage pipe 2 hole of the ground is greater, preventing the drainage pipe 2 from easily coming out of the drainage pipe 2 hole, improving the tensile strength of the pipe gallery, and further improving the safety of the pipe gallery.

[0033] In another embodiment, a sealing ring 1 is provided between the end of the insertion tube 24 and the bottom of the tube groove 25, and a sealing ring 2 is provided between adjacent connecting tubes 22. Both sealing ring 1 and sealing ring 2 are rubber sealing rings. The double-layer sealing prevents water leakage in the drainage pipe 2, so as to avoid the friction between the drainage pipe 2 and the drainage pipe 2 hole of the formation being reduced due to water seepage, thereby improving the practicality of the device.

[0034] Working principle: First, excavate a trench for the pipe gallery and drill two rows of drainage pipe holes on both sides of the trench. The depth of the drainage pipe holes needs to reach the aquifer of the stratum, or use the existing dewatering wells of the foundation pit. Then, connect the drainage pipes 2 section by section using connecting components 4 and insert them into the drainage pipe holes or dewatering wells, ensuring that the end of the locking plate 51 in the one-way locking component 5 connected to the unit pipe section 21 is on the lower side, so that the one-way locking component 5 will not act when the drainage pipe 2 is placed downwards, until the drainage pipe 2 reaches the aquifer of the stratum. Then, connect the horizontal water pipe 3 to the drainage pipe 2. After the connection is completed, pour the main body 1 of the pipe gallery, first pouring the bottom slab of the pipe gallery. Next, the side walls of the pipe gallery are poured, and finally the top slab of the pipe gallery is poured to complete the setting of the main body 1 of the pipe gallery. The outer wall 12 of the pipe gallery covers part of the horizontal water pipe 3. The horizontal water pipes 3 on the upper side of the main body 1 of the pipe gallery are connected to each other and then connected to the municipal drainage pipeline network. Pipe supports are set in the inner chamber 11 of the pipe gallery for placing pipes. When the water pressure of the underground aquifer is too high and water surges upward, it can be discharged into the municipal drainage pipeline along the drainage pipe 2 and the horizontal water pipe 3 to balance the high water pressure of the groundwater and prevent the groundwater from surging to the outside of the pipe gallery, which would cause the pipe gallery to be affected by buoyancy. At the same time, the drainage pipe 2 can also be connected to the stratum through the one-way locking component 5, which improves the firmness and stability of the connection between the pipe gallery and the stratum.
