Description

Technical Field

[0001] This utility model relates to the field of waterproofing technology for structures, specifically to a rigid waterproofing structure for water treatment structures. Background Technology

[0002] Among the many water treatment structures, water treatment tanks are an extremely important category. Water treatment tanks are further subdivided according to their specific functions. For example, sedimentation tanks can be divided into primary sedimentation tanks and secondary sedimentation tanks according to their process layout. Primary sedimentation tanks mainly remove inorganic particles and some organic matter from sewage, reducing the organic load on subsequent biological treatment structures. Secondary sedimentation tanks are used for sludge-water separation, making the effluent from biological treatment structures clear. Sedimentation tanks can also be divided into horizontal flow, vertical flow, radial flow, and inclined plate (tube) sedimentation tanks according to the direction of water flow within the tank. Different types are suitable for different application scenarios. Another example is the aeration tank, which plays a core role in the activated sludge process. By aerating the sewage, it provides a suitable living environment for microorganisms, enabling them to decompose the organic matter in the sewage, thereby achieving the purpose of sewage treatment.

[0003] Currently, water treatment tanks are typically constructed of concrete. Concrete has certain advantages, such as high strength, good durability, and economy, which can meet the basic structural stability requirements of water treatment tanks during daily operation. However, this type of concrete water treatment tank has a significant drawback. After prolonged operation, although the waterproof coating on the surface of the water treatment tank can provide some waterproofing, it is prone to seepage when the coating wears down. Once seepage occurs, moisture accumulates inside the concrete. When the moisture penetrates to the interface between the waterproof coating and the concrete layer, it weakens the bond between them. As the moisture increases, the internal expansion pressure continues to rise, eventually causing the concrete layer to crack and damage the water treatment tank, affecting its normal operation.

[0004] Therefore, it is of great importance to design a rigid waterproof structure for water treatment buildings to solve the above-mentioned defects. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model designs a rigid waterproof structure for water treatment structures. This rigid waterproof structure aims to solve the technical problem that water seepage easily occurs after the waterproof coating on the surface of water treatment structures wears down, leading to damage to the water treatment tank and affecting its normal operation.

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

[0007] A rigid waterproof structure for a water treatment building includes a pool bottom and a concrete wall. The concrete wall is fixedly connected to the outside of the pool bottom. The pool bottom consists of a top concrete layer, a permeable layer, a water collection layer, a waterproof layer, and a bottom concrete layer from top to bottom. The surfaces of the top concrete layer and the concrete wall are coated with a waterproof coating. A water guide hopper is fixedly connected inside the water collection layer. Multiple sets of drainage pipes are fixedly connected to the bottom of the water guide hopper. The multiple sets of drainage pipes are fixedly connected to each other through the water guide pipes.

[0008] As a preferred embodiment of this utility model, the permeable layer is a permeable board made of sand-free concrete, and the waterproof layer is made of asphalt waterproof membrane, which extends into the interior of the concrete wall.

[0009] As a preferred embodiment of this utility model, a reinforcing mesh is fixedly connected between the concrete base layer and the waterproof layer.

[0010] As a preferred embodiment of this utility model, the concrete base layer is internally fixedly connected with multiple sets of connecting reinforcing columns, and the outer side of the connecting reinforcing columns and the interior of the concrete base layer is fixedly connected with multiple sets of connecting plates, and the top of the connecting reinforcing columns abuts against the bottom of the water guide hopper.

[0011] As a preferred embodiment of this utility model, the waterproof coating is a cement-based penetrating crystalline waterproof coating, and an impact-resistant arc surface is provided at the joint between the concrete wall and the top concrete layer, located on the outside of the waterproof coating.

[0012] As a preferred embodiment of this utility model, the water guide bucket is made of galvanized steel plate, and both the drain pipe and the water guide pipe are made of galvanized steel pipe.

[0013] As a preferred embodiment of this utility model, the water guide bucket is fixedly connected with water-blocking edges on all four sides, and the water-blocking edges extend into the interior of the concrete wall.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, the design of the pool bottom and the concrete wall is coordinated, and a waterproof coating provides basic waterproofing for the pool bottom and the inner side of the concrete wall. When the waterproof coating wears down and seepage occurs, the seepage water quickly seeps down through the permeable layer to the collection layer, is collected by the water guide hopper, and then discharged through the drainage pipe and the water guide pipe, avoiding water accumulation. The multi-layer structure has a clear division of labor: the permeable layer accelerates drainage, and the collection layer and the water guide system work together to prevent seepage water accumulation and reduce the seepage pressure of the waterproof layer, thereby preventing the concrete structure from cracking and damaging the water treatment pool, ensuring the normal operation of the treatment pool. The bottom layer of the pool is reinforced with a concrete base layer and reinforced with a waterproof layer. Through the three-level coordination of surface waterproofing, middle drainage layer and bottom reinforcement, a unity of rigid waterproofing and structural stability is achieved.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to 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.

[0021] Example: Please refer to Figures 1-3 This utility model provides a technical solution:

[0022] A rigid waterproof structure for a water treatment facility includes a pool bottom 1 and a concrete wall 2. The concrete wall 2 is fixedly connected to the outside of the pool bottom 1. The pool bottom 1 consists of a top concrete layer 3, a permeable layer 4, a water collection layer 5, a waterproof layer 6, and a bottom concrete layer 7, arranged from top to bottom. Both the top concrete layer 3 and the concrete wall 2 are coated with a waterproof coating 8. A water guide hopper 9 is fixedly connected inside the water collection layer 5. Multiple sets of drainage pipes 10 are fixedly connected to the bottom of the water guide hopper 9. The multiple sets of drainage pipes 10 are fixedly connected to each other via water guide pipes 11. The waterproof coating 8 provides basic waterproofing for the pool bottom 1 and the inner side of the concrete wall 2. When the waterproof coating 8 wears down and water seeps in, the seepage water quickly seeps down through the permeable layer 4 to the collection layer 5, where it is collected by the water guide hopper 9 and discharged through the drain pipe 10 and the water guide pipe 11, preventing water accumulation. The multi-layer structure has a clear division of labor: the permeable layer 4 accelerates drainage, the collection layer 5 works in conjunction with the water guide system to prevent seepage water accumulation, and reduces the seepage pressure of the waterproof layer 6, thereby preventing the concrete structure from cracking and damaging the water treatment tank, ensuring the normal operation of the treatment tank. The bottom layer 1 of the tank is reinforced by a concrete base layer 7 and further waterproofed by the waterproof layer 6. Through the three-level synergy of surface waterproofing, middle drainage, and bottom reinforcement, a unity of rigid waterproofing and structural stability is achieved.

[0023] First, the permeable layer 4 is a permeable board made of no-fines concrete, and the waterproof layer 6 is made of asphalt waterproof membrane, which extends into the interior of the concrete wall 2. The high porosity of the no-fines concrete permeable board can accelerate the infiltration of water and reduce hydrostatic pressure, so that the infiltrated water can quickly seep into the interior of the water guide hopper 9 through the permeable layer 4 to avoid water accumulation. The waterproof layer 6 made of asphalt waterproof membrane is set in the bottom of the pool 1 and extends into the interior of the concrete wall 2 to form a continuous flexible sealing layer to adapt to structural deformation.

[0024] Furthermore, a reinforcing mesh 701 is fixedly connected between the concrete base layer 7 and the waterproof layer 6. The reinforcing mesh 701 is added between the waterproof layer 6 and the concrete base layer 7 to distribute the load and prevent the asphalt waterproof membrane from cracking.

[0025] Then, multiple sets of connecting reinforcing columns 702 are fixedly connected inside the concrete base layer 7. Multiple sets of connecting plates 703 are fixedly connected outside the connecting reinforcing columns 702 and inside the concrete base layer 7. The top of the connecting reinforcing columns 702 abuts against the bottom of the water guide hopper 9. The multiple sets of connecting reinforcing columns 702 vertically penetrate the concrete base layer 7, and the top of them abuts against the water guide hopper 9, directly transferring the load of the water guide hopper 9 to the base structure, avoiding local stress concentration, and preventing the water guide hopper 9 from displacing under the impact of drainage. The multiple sets of connecting plates 703 form a spatial truss structure, which significantly improves the overall bending stiffness of the concrete base layer 7. Both the reinforcing columns 702 and the connecting plates 703 are made of galvanized steel, and an anti-corrosion coating is set at the fixed connection with the concrete base layer 7 to adapt to the humid environment of the water treatment tank. This not only ensures the functionality of the water guiding system, but also improves the structural safety of the concrete base layer 7.

[0026] Furthermore, the waterproof coating 8 is a cement-based penetrating crystalline waterproof coating. An anti-impact arc surface 801 is provided at the joint between the concrete wall 2 and the top concrete layer 3, located on the outside of the waterproof coating 8. The cement-based penetrating crystalline coating generates dendritic crystals inside the concrete through active ingredients, which can block micro-cracks. The anti-impact arc surface 801 at the joint can effectively disperse the impact force of water flow, preventing the coating from being damaged locally due to long-term erosion, thereby maintaining the integrity of the crystals. Through chemical crystallization, it actively blocks the pores of the concrete, forming the first waterproof barrier. The anti-impact arc surface 801 at the joint alleviates water erosion and protects the integrity of the coating.

[0027] Secondly, the water guide hopper 9 is made of galvanized steel plate, and the drain pipe 10 and water guide pipe 11 are both made of galvanized steel pipe, which delays metal corrosion in humid environments and ensures long-term stability.

[0028] Finally, water-blocking edges 901 are fixedly connected around the water guide 9, and the water-blocking edges 901 extend into the interior of the concrete wall 2. The water-blocking edges 901 extend into the interior of the concrete wall 2, forcing water to seep through the water guide 9 into the drain pipe 10, preventing water from seeping laterally along the joint. At the same time, it works in conjunction with the pre-embedded steel bars in the wall to improve the overall stability of the water guide 9.

[0029] In this embodiment, the specific implementation scenario is as follows: A waterproof coating 8 provides basic waterproofing for the pool bottom 1 and the inner side of the concrete wall 2. The waterproof coating 8 is a cement-based penetrating crystalline waterproof coating that actively blocks concrete pores through chemical crystallization, forming the first waterproof barrier. An impact-resistant curved surface 801 is installed at the joints to mitigate water erosion and protect the coating's integrity. When the waterproof coating 8 wears down and seepage occurs, the permeable layer 4 accelerates the seepage downwards, reducing hydrostatic pressure. The seepage water quickly seeps down to the collection layer 5 through the permeable layer 4, is collected by the water guide 9, and discharged through the drain pipe 10 and the water guide pipe 11, preventing water accumulation. A waterproof layer 6 made of asphalt waterproof membrane is installed inside the pool bottom 1, extending into the concrete wall 2 to form a continuous flexible sealing layer that adapts to structural deformation. A reinforcing mesh 701 is added between the waterproof layer 6 and the concrete bottom layer 7 to distribute the load and prevent the asphalt waterproof membrane from cracking. Multiple sets of connecting reinforcing columns 702 vertically penetrate the concrete bottom layer 7, with their tops abutting against the water guide 9. The load of the water guide hopper 9 is directly transferred to the underlying structure, avoiding local stress concentration and preventing displacement of the water guide hopper 9 under drainage impact. Multiple sets of connecting plates 703 form a spatial truss structure, significantly improving the overall bending stiffness of the concrete underlying layer 7. The reinforcing columns 702 and connecting plates 703 are made of galvanized steel, and anti-corrosion coatings are applied at the fixed connection points with the concrete underlying layer 7 to adapt to the humid environment of the water treatment tank. This ensures both the functionality of the water guiding system and the structural safety of the concrete underlying layer 7. Water-retaining edges 901 are fixedly connected to all four sides of the water guide hopper 9, extending into the interior of the concrete wall 2. Forced water seepage enters the drainage pipe 10 through the water guide hopper 9, preventing water from seeping laterally along the joints. At the same time, it works in conjunction with the pre-embedded steel bars in the wall to improve the overall stability of the water guide hopper 9. The entire operation process is simple and convenient. This utility model achieves the unity of rigid waterproofing and structural stability through the three-level synergy of surface waterproofing, middle-layer drainage, and bottom-layer reinforcement.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
