Description

Technical Field

[0001] This utility model relates to the field of underground concrete structure seepage prevention technology, and in particular to a semi-underground pump house with seepage prevention structure. Background Technology

[0002] In municipal engineering, water conservancy, and hydropower projects, impermeable concrete is often used to enhance the impermeability of underground structures. Due to factors such as groundwater level reduction measures during construction and incomplete backfilling, the groundwater pressure during construction is far lower than the maximum design pressure. Therefore, small, difficult-to-inspect and treat cracks may appear in the concrete initially, not necessarily causing leakage. However, over time, factors such as concrete temperature stress and increased water pressure after backfilling cause cracks to grow or new cracks to appear, increasing the risk of leakage. Furthermore, the outer surface of most underground structures in current building projects is exposed, and this exposed surface, exposed to seasonal changes, poses potential risks of cracking and leakage. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a semi-underground pump house with a seepage-proof structure to address the above-mentioned problems.

[0004] The technical solution adopted in this utility model is: a semi-underground pump house with a seepage-proof structure, comprising:

[0005] Multiple pump rooms are buried underground and connected by corridors. Each pump room has an inlet pipe at its inlet end and an outlet pipe at its outlet end.

[0006] Multiple inlet wells are located on the upstream side of the pump house. The inlet wells are interconnected by connecting pipes and connected to the corresponding inlet pipes.

[0007] The outlet manifold is located on the outlet side of the pump room and is connected to the corresponding outlet pipe.

[0008] Waterproof components, installed at the joints of various pipes, can prevent water from seeping out of the corresponding pipes;

[0009] The impermeable layer, located on the outer wall of the pump house, prevents external water from seeping into the pump house.

[0010] Through the aforementioned technical means, the inlet well can deliver water to the pump house through the inlet pipe, and the outlet manifold can collect the water from the pump house's outlet pipe and allow it to flow out, thus forming the overall structure of the pump house. Waterproof components installed at the joints of each pipe can prevent water from seeping out of the corresponding pipe. An anti-seepage layer installed on the outside of the pump house can prevent external water from seeping into the pump house, thereby making the pump house a complete waterproof body. At the same time, the pump house is buried underground, unlike the pump house structure which is exposed to the outside, which can reduce the impact of external temperature and stress changes and reduce the risk of cracks.

[0011] In some embodiments, the impermeable layer is made of sprayed quick-setting rubber asphalt waterproof coating, and the spraying thickness of the impermeable layer is determined based on the external groundwater head value of the pump house.

[0012] Through the above-mentioned technical means, the sprayed quick-setting rubber asphalt waterproof coating has super strong adhesion performance. It can not only form a waterproof membrane on the surface of the pump room, but also has a certain self-healing and intelligent repair function. For pump rooms buried underground, it can reduce the damage of the surrounding backfill material to the waterproof material and minimize the risk of leakage.

[0013] In some embodiments, the quick-setting rubber asphalt waterproof coating is composed of two components, A and B. Component A is a brownish-brown viscous liquid, and component B is a colorless and transparent liquid curing agent. It is applied using a special spraying machine with the spray gun perpendicular to the concrete surface and the nozzle of the spray gun 0.6m away from the working surface. Components A and B are cross-mixed at a distance of 15cm to 20cm from the concrete surface to form a waterproof coating.

[0014] The weight ratio of the sprayed quick-setting rubber asphalt waterproof coating is A:(B+water)=10:1, and the weight ratio of (B+water) is B:water=1:9.

[0015] In some embodiments, the waterproof component includes a waterproof wing ring, and the connection between the water inlet pipe and the water inlet well is provided with a waterproof wing ring.

[0016] Through the above-mentioned technical means, the waterproof wing ring adopts a ring structure that can adapt to the shape and changes of the pipe connection. In addition, the waterproof wing ring has certain anti-torsion and anti-compression properties. The waterproof wing ring can enhance the tightness of the connection between the water inlet pipe and the water inlet well, thereby ensuring that the connection has good sealing performance and preventing internal water from seeping out from the connection.

[0017] In some embodiments, the waterproofing component includes a waterproof sleeve, and the connection between the outlet pipe and the pump house is provided with a waterproof sleeve.

[0018] Through the above-mentioned technical means, the connection between the outlet pipe and the pump house is protected to a certain extent by using a waterproof sleeve. The waterproof sleeve not only provides an extra protective layer for the connection of the outlet pipe, reducing the erosion and damage of the connection by external moisture, but also enables the connection between the outlet pipe and the pump house to have good sealing performance, effectively reducing the risk of internal water leakage.

[0019] In some embodiments, the connection between the inlet pipe and the outlet pipe on the side wall of the pump room is provided with anti-seepage treatment, which includes sealing with polyurethane sealant, rounding the corners with crack-resistant mortar, and applying rubber asphalt waterproof coating in sequence.

[0020] Using the above-mentioned technical means, seepage prevention treatment is applied to the wall-penetrating connections of some pipelines on the side wall of the pump house. Polyurethane sealant can fill and seal, effectively filling gaps or joints and preventing water leakage. Crack-resistant mortar has good crack resistance and can effectively protect the connection between the pipeline and the pump house wall from the influence of the external environment, improving the reliability and safety of the connection. Rubber asphalt waterproof coating can form a waterproof layer with good elasticity and durability, effectively preventing the leakage of water and other liquids, thereby enhancing the sealing and waterproof performance of the connection between the pump house and the pipeline.

[0021] In some embodiments, a structural joint is provided at the connection between the pump rooms, and two copper waterstops are arranged in the structural joint. The adjacent sides of the copper waterstops are filled with asphalt hemp fiber, and the structural joint is also filled with high-density polyethylene closed-cell foam board.

[0022] Through the above-mentioned technical means, copper waterstops have good waterproof performance. Placing them in the structural joints can effectively prevent external water from entering the pump room along the structural joints.

[0023] In some embodiments, an additional layer is provided between one end of the structural joint located on the outer wall of the pump house and the seepage-proof layer. The additional layer includes rubber asphalt waterproof coating and mesh fabric.

[0024] In some embodiments, the pump house adopts a cylindrical structure, and multiple pump houses are connected by a multi-cylinder thin-walled concrete structure.

[0025] In some embodiments, the pump house and the inlet well are arranged below the original ground line, and a frame structure is arranged above the ground of the pump house.

[0026] The beneficial effects of this utility model are:

[0027] 1. By spraying quick-setting rubber asphalt waterproof coating on the outside of the pump house to form an anti-seepage layer, this material can quickly form a dense waterproof layer on the base surface, thereby effectively preventing water from penetrating into the pump house. The waterproof components improve the sealing of the pipe connection and enhance the structural strength of the connection. The waterproof components and the anti-seepage layer work together to prevent external water from seeping into the pump house, and also prevent water in the pipe from seeping out or into the pump house.

[0028] 2. The sprayed quick-setting rubber asphalt waterproof coating has good extensibility and adaptability. When stone slag is backfilled around the pump house, it can reduce the risk of the external waterproof material of the pump house being damaged by the stone slag. It can also adapt to the small deformation and cracking of the base layer. Moreover, the backfilling of stone slag makes the pump house form a semi-underground structure. Compared with the form of the pump house with a completely exposed external structure, the semi-underground pump house can reduce the risk of damage to the seepage prevention layer caused by external factors such as temperature changes.

[0035] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below with reference to specific embodiments.

[0036] Combination Figures 1 to 4 As shown, this embodiment is a semi-underground pump house 1 with a seepage-proof structure, including multiple pump houses 1, multiple inlet wells 2, a water outlet manifold 5, waterproof components, and a seepage-proof layer. The multiple pump houses 1 are buried below the original ground level 12 and located on the water intake bank. A frame structure 11 is arranged above the ground level of the pump houses 1. The inlet end of the pump house 1 is equipped with an inlet pipe 8, and the outlet end of the pump house 1 is equipped with an outlet pipe. Multiple outlet pipes penetrating the side walls of the pump houses 1 are connected to the water outlet manifold 5. In this embodiment, the pump houses 1 have a cylindrical structure. The multiple pump houses 1 are connected by a multi-tube thin-walled concrete structure. The concrete wall itself has seepage-proof properties. The pump houses 1 are interconnected by corridors, and multiple structural joints are provided between the pump houses 1.

[0037] Furthermore, such as Figure 3As shown, two copper waterstops 7 are arranged within the structural joint to prevent water from seeping into the pump house 1 along the corridor. The adjacent sides of the copper waterstops 7 are filled with asphalt-impregnated hemp fibers, and the structural joint is also filled with high-density polyethylene closed-cell foam board. The copper waterstops 7 not only have good waterproofing performance, preventing water leakage through the structural joint, but also enhance the rigidity and stability of the structural joint. An additional layer is provided at one end of the structural joint located on the outer side of the pump house 1 cylinder wall. In this embodiment, the additional layer includes rubber asphalt waterproof coating and mesh fabric. The mesh fabric is first laid near the structural joint, and then the rubber asphalt waterproof coating is applied. The use of mesh fabric increases the crack resistance of the coating and reduces the risk of cracking due to stress.

[0038] An inlet well 2 is arranged on the upstream side of pump house 1. A water intake pipe 3 connecting to the river is arranged outside the inlet well 2, and the inlet wells 2 are interconnected by a connecting pipe 4. The inlet well 2 is connected to the water inlet pipe 8 of pump house 1. At the same time, the waterproof components include a waterproof wing ring 9 and a waterproof sleeve 10. A waterproof wing ring 9 is installed on the side wall of the inlet well 2 at the connection with the water inlet pipe 8. The waterproof wing ring 9 can prevent water in the inlet well 2 from seeping into pump house 1. A waterproof sleeve 10 is installed at the connection between the side wall of pump house 1 and the outlet pipe. The waterproof sleeve 10 can block external water from entering pump house 1.

[0039] Furthermore, the wall penetration points connecting the inlet pipe 8 and the outlet pipe on the side wall of pump room 1 are all treated with anti-seepage measures. These measures include first sealing with polyurethane sealant, then rounding the corners with crack-resistant mortar, and finally applying a rubber asphalt waterproofing material. The polyurethane sealant effectively fills gaps and joints, while the crack-resistant mortar provides excellent crack resistance, effectively protecting the connection between the pipe and the wall. The rubber asphalt waterproofing coating forms a highly elastic and durable waterproof layer, effectively preventing the leakage of water and other liquids.

[0040] After completing the detailed waterproofing treatment of the structural joints and pipe penetrations through the cylinder wall, a seepage-proof layer is added to the outer wall of pump house 1. In this embodiment, the seepage-proof layer is made of sprayed quick-setting rubber asphalt waterproof coating 6. The thickness of the sprayed quick-setting rubber asphalt waterproof coating 6 is determined based on the groundwater head value, ultimately ensuring the complete closure of the waterproof body of pump house 1. After the seepage-proof layer is added to the outside of pump house 1, stone chips 13 are backfilled around pump house 1.

[0041] The quick-setting rubber asphalt waterproof coating 6 has the following functions: excellent waterproof performance, combined with high adhesion and rapid solidification, it can quickly form a dense waterproof layer on the surface of the pump house 1, effectively preventing backfill soil from seeping into the pump house 1; strong adaptability, it can be used on the base material of the pump house 1 exterior; good extensibility, with super elasticity and extensibility, it can adapt to the deformation and cracking of pipe connections, effectively preventing leakage and cracking at pipe connections; the material itself has self-healing properties after being squeezed by backfill stone slag 13, intelligent repair function, effectively solving the problem of damage to waterproof materials by backfill stone slag 13, and can be sprayed on a large area quickly, minimizing the risk of water leakage.

[0042] Furthermore, such as Figure 4 As shown, the quick-setting rubber asphalt waterproof coating 6 in this embodiment consists of two components, A and B. Component A is a brownish-brown viscous liquid, and component B is a colorless, transparent liquid curing agent. A dedicated spraying machine is used for application. The spray gun should be perpendicular to the concrete surface, with the nozzle 0.6m away from the work surface. Components A and B should be cross-mixed at a distance of approximately 15cm to 20cm from the concrete surface to form a waterproof coating with a certain strength. Spraying should follow the principle of "details first, then large areas; from far to near; from low to high."

[0043] Specifically, the weight ratio of the above-mentioned sprayed quick-setting rubber asphalt waterproof coating 6 is A:(B+water)=10:1, and the weight ratio of (B+water) is B:water=1:9, where (B+water) is a mixture of component B and water.

[0044] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
