[0001] The present invention relates to the technical field of building drainage, and specifically to a siphon drainage system for water field box top water shielding in underground burial type.

Background Art

[0002] The water shielding of the box top of the underground burial type water field is a general term for a series of construction technical means adopted to prevent groundwater, surface water or rainwater from invading the interior of the main structure of the underground factory area from the top. The core goal is to ensure that the top of the underground box structure has reliable and continuous waterproof sealing performance. In addition, the siphon drainage system used for water shielding of the box top of the underground burial type water field is a planned drainage system with zero gradient that utilizes the physical principle of the siphon to actively, quickly and efficiently collect and forcibly discharge the infiltrated water and interstitial water in the soil covering layer on the box top.

[0003] In the siphon drainage tank inside the conventional siphon drainage system, no filter net is installed inside the water inlet tank. As large-particle foreign matters directly invade the drainage pipeline, blockage occurs in a short period, the drainage path is interrupted, and accumulated water cannot be discharged. In addition, for cleaning and dredging operations, it is necessary to remove the overlying soil above, and the difficulty of operation and maintenance is extremely high. As a result, the problem that the drainage system frequently fails has occurred.

Summary of the Invention

Problems to be Solved by the Invention

[0004] The purpose of the present invention is to provide a siphon drainage system for water shielding of the box top of the underground burial type water field in order to solve the problems raised in the above background art.

Means for Solving the Problems

[0005] To achieve the above object, the present invention adopts the following technical means: This is a siphon drainage system for waterproofing the top of an underground water tank enclosure, comprising a wall and a waterproof drainage plate. The waterproof drainage plate is installed at the bottom of the wall, a siphon drainage tank is installed at the top of the wall, and a self-adhering geotextile with irregularly shaped drainage pieces is provided on the outer wall of the siphon drainage tank, with the bottom end of the self-adhering geotextile with irregularly shaped drainage pieces connected to the wall. A sedimentation observation well is provided on one side of the outer wall of the wall, and a siphon pipe of different diameters is installed at the output end of the sedimentation observation well, with the top end of the siphon pipe of different diameters connected to the siphon drainage tank. The output end of the sedimentation observation well is connected to a water storage module via a transport pipeline, and a ventilation observation pipe is connected to the top of both the water storage module and the siphon drainage tank.

[0006] Inlet tanks are provided on both sides of the outer wall of the siphon drainage tank, and a filter net is connected inside the inlet tanks. A base plate is fixedly connected to one side of the outer wall of the filter net, and an engaging member is connected to the middle of the outer wall of the base plate. An engaging seat is connected to the bottom end of the engaging member, and a slanted end is provided on one side of the outer wall of the engaging seat, and a slanted portion is provided on one side of the bottom end of the engaging member.

[0007] The substrate is used for the simultaneous movement of the filter net, the filter net is used to block impurities such as gravel and stone, and the engaging member works in cooperation with the engaging seat to lock the substrate.

[0008] In the preferred solution, the water inlet tanks are distributed at equal intervals, the middle portion of the outer wall of the engagement seat is fixedly connected to the outer wall of the siphon drain tank, the engagement members have an L-shaped structure, and the engagement members are distributed at equal intervals.

[0009] The operator moves the substrate to bring multiple sets of filter nets and engaging members closer to the siphon drain tank, moving the engaging members until they approach the engaging seats. At this time, the slanted portion of the outer wall of the engaging member comes into contact with the slanted end of the outer wall of the engaging seat, causing deformation of the engaging member. As the filter nets extend into the water inlet tank, the engaging members return to their original position and engage with the inside of the engaging seats, locking the substrate and the filter nets connected to it.

[0010] In the preferred design, reinforcing bars are fixedly connected to both sides of the top of the inner wall of the siphon drain tank, and the reinforcing bars have a triangular structure, and the filter net is installed at an angle.

[0011] Reinforcement bars are used to improve the structural strength of the siphon drainage tank.

[0012] In the preferred configuration, a base unit No. 1 is fixedly connected to one side of the outer wall of the siphon drainage tank, and a base unit No. 2 is fixedly connected to the other side of the outer wall of the siphon drainage tank, with a locking tooth No. 1 connected to the middle of the top end of base unit No. 1, and a locking tooth No. 2 connected to the middle of the top end of base unit No. 2.

[0013] As the base unit No. 1 moves, the locking teeth No. 1 and the sealing member move together, and at this time the locking teeth No. 1 and No. 2 come into contact and interlock, locking the siphon drain tank.

[0014] In the preferred solution, a sealing member is fixedly connected to the middle of the outer wall of the base unit No. 1, and a sealing groove corresponding to the sealing member is provided inside the base unit No. 2, with a sealing pad connected to one side of the sealing member away from the base unit No. 1.

[0015] After the siphon drain tank is connected, the sealing member, along with the sealing pad, extends into the sealed groove. At this time, the sealing member is inserted into the base of the second unit, restricting the movement of the siphon drain tank. Simultaneously, the mutual cooperation of the sealing pad and the sealed groove ensures the airtightness of the siphon drain tank connection point and prevents leakage. [Effects of the Invention]

[0016] As described above, the siphon drainage system for waterproofing the top of an underground water source box provided by this invention has the following beneficial effects. 1. The toothed interlocking connection structure of the siphon drain tank, namely the No. 1 base, No. 2 base, No. 1 locking tooth, and No. 2 locking tooth, works in cooperation with the double seal design, namely the sealing member, sealing pad, and sealing groove, to improve construction efficiency while simultaneously guaranteeing waterproofing performance at the connection point and shortening construction time.

[0017] 2. The elastic engagement structure of the filter net, that is, the substrate, the engagement member, the engagement seat, the inclined surface portion and the inclined surface end enable the quick attachment and detachment of the filter net. Also, the inclined design achieves both an enlarged filtration area and self-cleaning ability, reducing the probability of blockage.

Embodiment for Implementing the Invention

[0020] Referring to FIGS. 1 - 11, the present invention provides a siphon drainage system for waterproofing the top of an underground buried water field box body, comprising a wall body 1 and a waterproof and drainage board 2. The waterproof and drainage board 2 is installed at the bottom end of the wall body 1, the siphon drainage tank 3 is installed at the top end of the wall body 1, and a self - adhering geotextile with drainage irregularity pieces 4 is provided on the outer wall of the siphon drainage tank 3. The bottom end of the self - adhering geotextile with drainage irregularity pieces 4 is connected to the wall body 1. A sediment observation well 6 is provided on one side of the outer wall of the wall body 1, and a siphon reducing pipe 5 is installed at the output end of the sediment observation well 6. The top end of the siphon reducing pipe 5 is connected to the siphon drainage tank 3. The output end of the sediment observation well 6 is connected to the water storage module 7 through a transport pipeline, and ventilation observation pipes 8 are connected to both the top of the water storage module 7 and the siphon drainage tank 3.

[0021] Water inlet tanks 9 are opened on both sides of the outer wall of the siphon drainage tank 3, a filter net 10 is connected inside the water inlet tank 9, a substrate 11 is fixedly connected to one side of the outer wall of the filter net 10, an engaging member 12 is connected to the middle of the outer wall of the substrate 11, an engaging seat 13 is connected to the bottom end of the engaging member 12, an inclined surface end 15 is opened on one side of the outer wall of the engaging seat 13, and an inclined surface part 14 is opened on one side of the bottom end of the engaging member 12.

[0022] The substrate 11 is used for the collective movement of the filter net 10. The filter net 10 is used for blocking impurities such as gravel and stones. The engaging member 12 is used in cooperation with the engaging seat 13 to lock the substrate 11.

[0023] The water inlet tanks 9 are distributed at equal intervals, the middle of the outer wall of the engagement seat 13 is fixedly connected to the outer wall of the siphon drain tank 3, the engagement members 12 have an L-shaped structure and are distributed at equal intervals. Reinforcing bars 16 are fixedly connected to both sides of the top of the inner wall of the siphon drain tank 3, and the reinforcing bars 16 have a triangular structure, and the filter net 10 is installed at an angle. A base seat 17 is fixedly connected to one side of the outer wall of the siphon drain tank 3, and a base seat 28 is fixedly connected to the other side of the outer wall of the siphon drain tank 3, a locking tooth 19 is connected to the middle of the top of the base seat 17, and a locking tooth 20 is connected to the middle of the top of the base seat 28. A sealing member 21 is fixedly connected to the middle of the outer wall of the first base 17, and a sealing groove 23 corresponding to the sealing member 21 is provided inside the second base 18, with a sealing pad 22 connected to one side of the sealing member 21 away from the first base 17.

[0024] In specific implementation, referring to Figure 1, the waterproof drainage plate 2 serves as an integrated waterproofing and drainage barrier for the wall 1, combining the dual functions of waterproofing and drainage. On the one hand, it blocks the infiltration path of groundwater into the interior of the water tank box, and on the other hand, it collects the infiltrated water from the side walls and guides it to the siphon drainage system. The self-adhering drainage rib geotextile 4 creates a continuous drainage cavity at the top of the box, quickly collecting rainwater and infiltrated water, preventing accumulated water from accumulating on the surface of the waterproofing layer and reducing the osmotic pressure damage to the waterproofing layer. At the same time, its convex ribs support the load of the upper cover soil or pavement, preventing the covering layer from pressing against the waterproofing layer. The siphon drainage tank 3, as the core water collection unit, uniformly collects the dispersed water flow of the drainage layer to form a stable flow state, and when the accumulated water reaches the design activation water level, it triggers a siphon effect, causing the water flow to rapidly enter the siphon pipe 5 to complete the discharge. The ventilation observation pipe 8 expels residual air from the pipe during the siphon activation phase, aiding in the rapid formation of a full-flow state, and introduces external air at the end of the siphon phase to balance the negative pressure in the pipeline, preventing deformation of the tank body due to negative pressure. The sedimentation observation well 6 recovers the water flow discharged from the siphon system, achieving separation of mud and foreign matter by gravity sedimentation and preventing blockage of the downstream pipeline. At the same time, it allows for intuitive observation of the sedimentation status in the well, enabling regular cleaning and dredging maintenance, and also functions as a pre-treatment unit for rainwater resource recovery. The treated rainwater can be used in applications such as greening irrigation, improving the efficiency of water resource utilization. The water storage module 7 temporarily stores excess rainwater discharged from the siphon drainage system during the rainy season, and achieves peak-shift discharge through a modular cavity, preventing large amounts of rainwater from being discharged directly into municipal pipelines in a short period of time, easing the load on the pipelines and reducing the risk of inland flooding in areas surrounding underground water facilities.

[0025] Referring to Figures 9 and 11, the operator drives the substrate 11, bringing multiple sets of filter nets 10 and engaging members 12 closer to the siphon drain tank 3. When the inclined portion 14 of the engaging member 12 contacts the inclined end 15 of the engaging seat 13, elastic deformation occurs in the engaging member 12. As the filter nets 10 extend into the water inlet tank 9, the engaging member 12 elastically returns to its original position and engages with the locking hole of the engaging seat 13, completing the locking and securing of the substrate 11 and the filter nets 10 connected to it.

[0026] Referring to Figures 7 and 8, the filter net 10 effectively blocks large-particle foreign matter in the water flow, and the inclined arrangement of the filter net 10 significantly increases the effective filtration area, reduces the water flow velocity per unit area, and decreases impact wear of the filter net 10 due to foreign matter, while simultaneously reducing the probability of blockage. At the same time, the installation of reinforcing bars 16 effectively improves the overall structural strength and deformation resistance capacity of the siphon drain tank 3.

[0027] Referring to Figures 3 and 6, in the connection work of the siphon drain tank 3, first, adjacent tank bodies are brought closer together and moved until the first base 17 and the second base 18 are in close contact. As the first base 17 moves, the first locking tooth 19 and the sealing member 21 are displaced synchronously, and at this time the first locking tooth 19 and the second locking tooth 20 engage and lock, thereby achieving the connection and fixing of the siphon drain tank 3.

[0028] Referring to Figures 5 and 6, after the connection of the siphon drain tank 3 is completed, the sealing member 21, along with the sealing pad 22, is fitted into the sealed groove 23. After the sealing member 21 is inserted into the cavity of the second base 18, it further restricts the relative displacement of the tank body, and at the same time, the tight contact between the sealing pad 22 and the sealed groove 23 ensures the sealing performance of the connection point of the siphon drain tank 3 and prevents leakage of seeping water.

[0029] The toothed interlocking connection structure of the siphon drain tank 3, namely the No. 1 base 17, No. 2 base 18, No. 1 locking tooth 19, and No. 2 locking tooth 20, works in cooperation with the double seal design, namely the sealing member 21, sealing pad 22, and sealing groove 23, to improve construction efficiency while simultaneously guaranteeing waterproofing performance at the connection point, thereby shortening construction time.

[0030] The elastic engagement structure of the filter net 10, namely the substrate 11, engaging member 12, engaging seat 13, inclined surface 14, and inclined surface end 15, enables the filter net 10 to be quickly attached and detached. Furthermore, the inclined design achieves both an increased filtration area and self-cleaning capacity, reducing the probability of blockage.
