Description

Technical Field

[0001] This utility model patent relates to the technical field of waterproof structures, specifically to a triple waterproof structure for expansion joints in ultra-long concrete pool walls of water plants. Background Technology

[0002] With the acceleration of urbanization, the development and utilization of urban underground space is becoming more and more frequent. Municipal water plant projects (such as waterworks and sewage treatment plants) are gradually developing towards semi-underground or fully underground structures. Although this layout saves space, it also brings new technical challenges, especially in terms of waterproofing and structural stability.

[0003] The expansion joints are mainly used to accommodate deformations caused by factors such as temperature changes, uneven foundation settlement, and earthquakes in water plant engineering structures, in order to prevent damage to the structures.

[0004] In existing technologies, the waterproofing structure of expansion joints is usually quite simple, using only waterstops, sealant, or caulking materials. This structure is characterized by its simplicity and low cost, but it is difficult to effectively prevent water penetration when faced with problems such as acidic or alkaline sewage erosion and pressure differences between the inside and outside of the pool wall.

[0005] When facing complex underground environments, expansion joints not only need to be waterproof, but also need to meet multiple requirements such as deformation resistance, corrosion resistance, and aging resistance. Existing waterproof structures cannot meet these requirements at the same time, resulting in poor waterproofing effect of expansion joints. Utility Model Content

[0006] The purpose of this invention is to provide a triple waterproof structure for the expansion joints of ultra-long concrete pool walls in water plants, aiming to solve the problem that the single waterproof structure of expansion joints in the prior art has poor waterproofing effect.

[0007] This utility model is implemented as follows: a triple waterproof structure for the expansion joints of an ultra-long concrete pool wall in a water plant, including expansion joints formed in the concrete pool wall and arranged longitudinally. The concrete pool wall has a back water surface and a front water surface. The expansion joints penetrate the back water surface to form a back water opening, and the expansion joints penetrate the front water surface to form a front water opening.

[0008] A waterstop is provided in the middle of the expansion joint. The waterstop includes an elastic cylinder, and winged bands extend from both sides of the elastic cylinder. The elastic cylinder seals the middle of the expansion joint, and the winged bands extend into the concrete pool wall.

[0009] The expansion joint has a water-facing area located between the elastic cylinder and the water-facing opening, the water-facing area being filled with a water-facing sealant and a water-stopping rod, and the water-facing opening being sealed with water-facing sealant; the expansion joint also has a back-water area located between the elastic cylinder and the back-water opening, the back-water area being filled with a back-water sealant, and the back-water opening being sealed with back-water sealant.

[0010] Furthermore, the concrete pool wall is provided with a steel reinforcement frame, and the wing strip is embedded in the steel reinforcement frame and clamped and fixed by the steel reinforcement frame.

[0011] Furthermore, the steel reinforcement frame is provided with a clamping groove, which is arranged perpendicular to the expansion joint, and the wing strip is embedded in the clamping groove.

[0012] Furthermore, the concrete pool wall is provided with multiple positioning steel bars, which extend along the height direction of the concrete pool wall, and the steel bar frame is fixedly connected to the multiple positioning steel bars respectively.

[0013] Furthermore, the steel reinforcement frame is arranged in a bent shape, forming multiple bent positions, and the positioning steel bars are inserted in the bent positions and fixedly connected to the steel reinforcement frame.

[0014] Furthermore, the water-facing sealant and the backwater sealant are both made of polyethylene foam material.

[0015] Furthermore, the water-facing sealant and the water-repellent sealant are both two-component polysulfide sealants.

[0016] Furthermore, along the direction from the elastic cylinder to the water-facing opening, the water-facing sealant, the water-stop rod, and the water-facing sealant are sequentially filled and arranged, with the water-facing sealant pressing against the elastic cylinder and the water-stop rod being clamped between the water-facing sealant and the water-facing sealant.

[0017] Furthermore, two water-stopping rods are provided in the water-facing area, and the two water-stopping rods are arranged in sequence to press against the water-facing opening along the direction from the elastic cylinder to the water-facing opening.

[0018] Furthermore, the backwater sealant plate presses against the elastic cylinder, and the elastic cylinder is fixed by the opposing pressure of the frontwater sealant plate and the backwater sealant plate.

[0019] Compared with existing technologies ， The triple waterproof structure for the expansion joint of the ultra-long concrete pool wall in the water plant provided by this utility model forms a triple waterproof structure through the combination of waterstop, joint filling material (water-facing joint filling board, waterstop rod, and back-facing joint filling board) and sealant. It effectively prevents water from seeping from the water-facing side to the back-facing side. By utilizing the synergistic effect of multiple materials, it can better adapt to the long-term humid environment and water pressure changes in the water plant, significantly improving the waterproof effect limitations of the single waterproof structure of the expansion joint, thus achieving a better waterproof effect for the expansion joint.

[0020] In addition, the elastic tube of the waterstop seals the middle of the expansion joint, and the wing strips on both sides extend into the concrete pool wall, which enhances the fixing effect and the ability to adapt to deformation of the waterstop. In addition, the different treatment arrangements for the water-facing area and the back water-facing area enable the waterproofing needs of different surfaces to be met separately, further improving the waterproofing effect.

[0028] Reference Figure 1-2 The image shown is a preferred embodiment of the present invention.

[0029] The water plant's extra-long concrete pool wall has a triple waterproof structure for expansion joints, including expansion joints 200 formed in the concrete pool wall 100 and arranged longitudinally. The concrete pool wall 100 has a back water surface 101 and a front water surface 102. Expansion joints 200 penetrate the back water surface 101 to form a back water opening, and expansion joints 200 penetrate the front water surface 102 to form a front water opening.

[0030] A waterstop 201 is provided in the middle of the expansion joint 200. The waterstop 201 includes an elastic cylinder 202. Winged bands 203 extend from both sides of the elastic cylinder 202. The elastic cylinder 202 seals the middle of the expansion joint 200, and the winged bands 203 extend into the concrete pool wall 100.

[0031] The expansion joint 200 has a water-facing area located between the elastic cylinder 202 and the water-facing opening, the water-facing area being filled with a water-facing sealant 204 and a water-stop rod 205, and the water-facing opening being sealed with a water-facing sealant 206; the expansion joint 200 also has a back-water area located between the elastic cylinder 202 and the back-water opening, the back-water area being filled with a back-water sealant 207, and the back-water opening being sealed with a back-water sealant 208.

[0032] The aforementioned triple waterproofing structure for the expansion joint of the ultra-long concrete pool wall in the water plant, through the combination of waterstop 201, joint filling materials (water-facing joint filling board 204, waterstop rod 205, and back-facing joint filling board 207) and sealant, forms a triple waterproofing structure. This effectively prevents water from seeping from the water-facing side 102 to the back-facing side 101. By utilizing the synergistic effect of multiple materials, it can better adapt to the long-term humid environment and water pressure changes in the water plant, significantly improving the limitations of the single waterproofing structure of the expansion joint 200, thus achieving a better waterproofing effect for the expansion joint 200.

[0033] In addition, the elastic cylinder 202 of the waterstop 201 is sealed in the middle of the expansion joint 200, and the wing strips 203 on both sides extend into the concrete pool wall 100, which enhances the fixing effect and the ability to adapt to deformation of the waterstop 201. In addition, the different treatment arrangements for the water-facing area and the back water-facing area enable the waterproofing needs of different surfaces to be met separately, further improving the waterproofing effect.

[0034] In this embodiment, a steel frame 103 is provided in the concrete pool wall 100, and the wing strip 203 is embedded in the steel frame 103 and clamped and fixed by the steel frame 103.

[0035] This ensures that the wing strips 203 of the waterstop 201 remain stable during the concrete pouring process, preventing the wing strips 203 from shifting due to external forces or concrete flow. Through the clamping and fixing of the steel frame 103, the waterstop 201 is more firmly bonded to the concrete pool wall 100, thereby effectively improving the deformation resistance and stability of the waterstop 201.

[0036] In this embodiment, the steel reinforcement frame 103 is provided with a clamping groove, which is arranged perpendicularly to the expansion joint 200, and the wing strip 203 is embedded in the clamping groove.

[0037] The groove provides precise positioning and reliable support for the wing strip 203, making its position in the concrete pool wall 100 more accurate. The vertically arranged groove structure ensures that the wing strip 203 distributes stress evenly when under load, further enhancing the deformation resistance of the waterstop strip 201.

[0038] In this embodiment, a plurality of positioning steel bars 104 are provided in the concrete pool wall 100. The positioning steel bars 104 extend along the height direction of the concrete pool wall 100, and the steel bar frame 103 is fixedly connected to the plurality of positioning steel bars 104 respectively.

[0039] By fixing the positioning steel bar 104 to the steel bar frame 103, a stable support system is formed, which makes the position of the steel bar frame 103 in the concrete pool wall 100 accurate and firmly fixed. This not only improves the stability of the steel bar frame 103, but also enhances the structural strength of the entire concrete pool wall 100, providing reliable support for the waterproof structure of the expansion joint 200.

[0040] In this embodiment, the steel reinforcement frame 103 is arranged in a bent shape, forming multiple bent positions 105. The positioning steel reinforcement 104 passes through the bent positions 105 and is fixedly connected to the steel reinforcement frame 103.

[0041] The bent steel frame 103 can better adapt to the shape and structural requirements of the concrete pool wall 100. At the same time, the stability and deformation resistance of the steel frame 103 are further enhanced by the insertion and fixing of the positioning steel bars 104.

[0042] In this embodiment, the water-facing sealant 204 and the water-repellent sealant 207 are both made of polyethylene foam material.

[0043] Because polyethylene foam has good elasticity and compression resistance, it can maintain a certain elastic recovery ability when the expansion joint 200 deforms. It can not only effectively fill the gaps in the expansion joint 200, but also adapt to the expansion and contraction of the expansion joint 200, thereby ensuring the stability and reliability of the waterproof structure during long-term use and helping to improve the waterproof effect of the expansion joint 200.

[0044] In this embodiment, the water-facing sealant 206 and the back-facing sealant 208 are two-component polysulfide sealants.

[0045] Because of its excellent waterproof performance, weather resistance and durability, the two-component polysulfide sealant can maintain a good sealing effect for a long time under complex environmental conditions. It not only effectively seals the opening of the expansion joint 200 to prevent water penetration, but its durability also ensures that the waterproof structure will not fail due to material aging during long-term use, further improving the waterproof effect of the expansion joint 200.

[0046] In this embodiment, along the direction from the elastic cylinder 202 to the water-facing opening, the water-facing sealant 204, the water-stop rod 205, and the water-facing sealant 206 are sequentially filled and arranged. The water-facing sealant 204 presses against the elastic cylinder 202, and the water-stop rod 205 is clamped between the water-facing sealant 204 and the water-facing sealant 206.

[0047] By sequentially filling the structure, multiple waterproof barriers can be formed. The combination of the water-facing sealant 204 and the water-stop bar 205 can effectively block the penetration of water, while the water-facing sealant 206 further seals any possible tiny gaps. The synergistic effect of multiple waterproof measures significantly improves the waterproof performance of the expansion joint 200 and solves the problem of poor waterproof effect of a single waterproof structure in the prior art.

[0048] In this embodiment, two water-stopping rods 205 are provided in the water-facing area. Along the direction from the elastic cylinder 202 to the water-facing opening, the two water-stopping rods 205 are arranged to press against each other in sequence.

[0049] By setting two water-stop rods 205, the waterproofing capability of the water-facing area can be further enhanced. The sequential pressing arrangement of the two water-stop rods 205 can effectively block the penetration path of water and form a more reliable waterproof barrier, thus differentiating it from the structure using a single water-stop rod 205 and enhancing the waterproofing effect of the expansion joint 200.

[0050] In this embodiment, the backwater sealant 207 presses against the elastic cylinder 202, and the elastic cylinder 202 is fixed by the water-facing sealant 204 and the backwater sealant 207 pressing against each other.

[0051] This ensures that the elastic cylinder 202 is in a stable position within the expansion joint 200. At the same time, the opposing pressure of the water-facing sealant plate 204 and the backwater sealant plate 207 enhances the fixing effect and waterproof performance of the elastic cylinder 202, effectively preventing displacement of the elastic cylinder 202 due to deformation or uneven stress.

[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
