Description

Technical Field

[0001] This utility model relates to the field of sedimentation tank technology, specifically to a seepage prevention and reinforcement structure for sedimentation tanks in water plants. Background Technology

[0002] As a core structure in water treatment processes, sedimentation tanks in water plants remove suspended particulate matter from water through gravity settling. To ensure the structural stability and airtightness of sedimentation tanks, traditional construction often employs a process of integrally casting the bottom slab and side slabs, utilizing the integrity of reinforced concrete to enhance structural strength and impermeability.

[0003] However, in actual engineering projects, due to the thermal expansion and contraction characteristics of concrete, changes in ambient temperature and humidity, and uneven distribution of internal stress during the pouring process, shrinkage cracks or temperature cracks are prone to occur on the surface and inside of the structure. These cracks are mostly concentrated in the stress concentration area at the junction of the bottom slab and the side slabs, and gradually expand into through expansion joints over time, causing water in the pool to seep into the ground through the cracks, resulting in leakage problems.

[0004] In existing technologies, measures such as pre-embedded waterstops, expansion joint fillers, or waterproof coatings are commonly used to mitigate the risk of leakage. However, the interface between the waterstop and the concrete is prone to peeling due to material aging, construction deviations, or foundation settlement, leading to seal failure. Furthermore, artificial sealants, limited by weather resistance and elastic recovery, are susceptible to embrittlement and detachment under long-term hydraulic erosion and chemical corrosion. In addition, leakage in sedimentation tanks not only wastes water resources but may also trigger secondary disasters such as groundwater and soil pollution and foundation erosion, threatening the safety of the structure.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0024] The following is for reference Figures 1-2As shown in the figure, and further explained with reference to specific embodiments, this embodiment provides a seepage prevention and reinforcement structure for a sedimentation tank in a water plant. The sedimentation tank includes a tank body 100, which includes a bottom wall 10 and a side wall 20. The bottom wall 10 and the side wall 20 are respectively provided with a bottom plate casting area 11 and a side plate casting area 21. Both the bottom plate casting area 11 and the side plate casting area 21 are used to pour concrete to form the bottom plate and the side plate.

[0025] The seepage prevention and reinforcement structure includes a first plate 30 and a second plate 40 respectively located in the bottom slab casting area 11 and the side plate casting area 21. The lengths of the first plate 30 and the second plate 40 are the same as the lengths of the bottom slab casting area 11 and the side plate casting area 21, respectively. The first plate 30 is horizontally located on the side of the bottom slab casting area 11 away from the bottom wall 10 of the pool, and the second plate 40 is vertically located on the side of the side plate casting area 21 away from the side wall 20 of the pool. The second plate 40 is fixedly connected to the top edge of the first plate 30.

[0026] The first plate 30 refers to a rigid flat plate component disposed on the surface of the base plate casting area 11. It can be made of steel plate or fiber-reinforced composite material, and its length is adapted to the base plate casting area 11 to form a continuous covering surface. The second plate 40 refers to a rigid vertical plate component vertically disposed on the outside of the side plate casting area 21. It can be made of the same material as the first plate 30, and its length is adapted to the side plate casting area 21 to form longitudinal protection. The two are fixedly connected by welding or bolting, forming a combined structure that cooperates in bearing loads.

[0027] When concrete is poured into the base slab casting area 11 and the side slab casting area 21, and the base slab and side slab are formed, the first plate 30 and the second plate 40 form a rigid connection node at the corner of the base slab and side slab, constituting a reinforced support system. When the pool body 100 deforms due to temperature changes, the first plate 30 and the second plate 40 limit the expansion of cracks through their own stiffness. At the same time, the rigid constraint at the connection prevents the plate from cracking due to displacement differences, thereby effectively reducing stress concentration at the junction of the base slab and side slab, preventing crack formation, and reducing the risk of leakage.

[0028] Furthermore, a vertical plate 31 is provided on the side of the first plate 30 facing the bottom wall 10 of the pool. One end of the vertical plate 31 is fixedly connected to the first plate 30, and the other end of the vertical plate 31 extends vertically toward the bottom wall 10 of the pool. A horizontal plate 41 is provided on the side of the second plate 40 facing the side wall 20 of the pool. One end of the horizontal plate 41 is fixedly connected to the second plate 40, and the other end of the horizontal plate 41 extends horizontally toward the side wall 20 of the pool.

[0029] The vertical plate 31 extends vertically and is embedded in the concrete layer of the bottom slab pouring area 11 to form a longitudinal anchoring structure, which can restrain the lateral displacement of the bottom slab pouring area 11 caused by temperature changes; the horizontal plate 41 extends horizontally and is embedded in the concrete layer of the side plate pouring area 21 to form a lateral anchoring structure, which can suppress the vertical deformation of the side plate pouring area 21 caused by foundation settlement. The combination of the vertical plate 31 and the horizontal plate 41 can effectively disperse the internal stress generated when the concrete shrinks, thereby reducing the probability of crack formation.

[0030] Furthermore, the vertical extension length of the vertical plate 31 is equal to the height of the bottom plate casting area 11, and the height of the bottom plate casting area 11 is the distance from the bottom wall 10 of the pool to the first plate 30.

[0031] Furthermore, the horizontal extension length of the horizontal plate 41 is equal to the width of the side plate casting area 21, and the width of the side plate casting area 21 is the distance from the pool side wall 20 to the second plate 40.

[0032] By extending the vertical plate 31 and the horizontal plate 41 respectively, the length of the vertical plate 31 is equal to the distance from the bottom wall 10 of the pool to the first plate 30, and the length of the horizontal plate 41 is equal to the distance from the side wall 20 of the pool to the second plate 40, the connection strength between the first plate 30 and the second plate 40 is further improved, thereby reducing the risk of leakage.

[0033] Furthermore, a third plate 311 and a fourth plate 411 are respectively provided on the vertical plate 31 and the horizontal plate 41. The third plate 311 and the fourth plate 411 are parallel to the first plate 30 and the second plate 40, respectively, and the third plate 311 and the fourth plate 411 are respectively used to abut against the bottom wall 10 and the side wall 20 of the pool.

[0034] The third plate 311 refers to a planar component fixed to the end of the vertical plate 31 and parallel to the first plate 30. It can be made of steel plate and fixed to the end of the vertical plate 31 by mechanical connection or welding. It is used to disperse the stress on the bottom plate casting area 11. The fourth plate 411 refers to a planar component fixed to the end of the horizontal plate 41 and parallel to the second plate 40. It can be made of the same material and connection method as the third plate 311. It is used to balance the lateral pressure of the side plate casting area 21.

[0035] After the third plate 311 is installed along the extension direction of the vertical plate 31, its surface forms a surface contact with the bottom wall 10 of the pool, thereby absorbing the lateral displacement caused by concrete shrinkage. After the fourth plate 411 is installed along the extension direction of the horizontal plate 41, its surface forms a surface contact with the side wall 20 of the pool, further constraining the deformation of the side plate area. When the concrete is poured, the third plate 311 and the fourth plate 411 form a double constraint through rigid contact, limiting the expansion of cracks along the junction of the bottom plate and the side plate.

[0036] Furthermore, a first hook portion 312 and a second hook portion 412 are respectively provided on the vertical plate 31 and the horizontal plate 41. The first hook portion 312 and the second hook portion 412 are parallel to the first plate body 30 and the second plate body 40, respectively, and both the first hook portion 312 and the second hook portion 412 extend in a direction away from the connection between the first plate body 30 and the second plate body 40.

[0037] The first hook 312 on the vertical plate 31 extends parallel to the first plate 30 and embeds itself into the concrete of the bottom plate pouring area 11, forming a multi-point anchoring effect. The second hook 412 on the horizontal plate 41 extends parallel to the second plate 40 and embeds itself into the concrete of the side plate pouring area 21, forming a multi-point anchoring effect. During concrete pouring, the hooks mechanically interlock with the concrete, dispersing the stress caused by temperature changes or foundation settlement. When the concrete shrinks or expands, the contact surfaces of the first hook 312 and the second hook 412 with the concrete generate friction and mechanical restraint, limiting the crack propagation path and thus reducing the risk of leakage.

[0038] Furthermore, a first connecting plate 313 and a second connecting plate 413 are respectively provided on the vertical plate 31 and the horizontal plate 41. The first connecting plate 313 and the second connecting plate 413 are parallel to the first plate body 30 and the second plate body 40, respectively. One end of the first connecting plate 313 and the second connecting plate 413 are fixedly connected to the first plate body 30 and the second plate body 40, respectively, and the other end of the first connecting plate 313 and the second connecting plate 413 extends towards the connection point of the first plate body 30 and the second plate body 40 until they abut against each other and are fixedly connected.

[0039] When the vertical plate 31 and the horizontal plate 41 experience relative displacement due to temperature changes or foundation settlement, the first connecting plate 313 and the second connecting plate 413 form a rigid support structure by extending parallel to the first plate 30 and the second plate 40. One end of the first connecting plate 313 is fixed to the first plate 30, which bears the vertical load, and the other end extends towards the connection point; one end of the second connecting plate 413 is fixed to the second plate 40, which bears the horizontal load, and the other end extends towards the connection point. After contacting each other at the connection point, the two plates are connected by welding or bolts to form a whole, so that the force between the vertical plate 31 and the horizontal plate 41 can be transmitted along the first connecting plate 313 and the second connecting plate 414 to the first plate 30 and the second plate 40, avoiding stress concentration in the junction area of ​​the bottom plate and the side plate.

[0040] Furthermore, both the vertical plate 31 and the horizontal plate 41 are provided with several through holes 314 for concrete to pass through.

[0041] During pouring, concrete enters the internal area formed by the first plate 30, the second plate 40, the vertical plate 31, and the horizontal plate 41 through the through holes 314 on the vertical plate 31 and the horizontal plate 41, and fills the internal area, thereby making the connection between the first plate 30, the second plate 40, the vertical plate 31, the horizontal plate 41, the first connecting plate 313, and the second connecting plate 413 more secure, and improving the overall strength of the entire seepage prevention and reinforcement structure.

[0042] Furthermore, the first plate 30 and the second plate 40 cooperate to form an L-shaped structure.

[0043] Furthermore, a reinforcing plate 50 is provided at the connection between the first plate 30 and the second plate 40. The cross-section of the reinforcing plate 50 is an isosceles right triangle, and the two right-angled sides of the reinforcing plate 50 are fixedly connected to the first plate 30 and the second plate 40, respectively.

[0044] The first plate 30 is horizontally arranged above the bottom slab casting area 11 of the pool body 100, and the second plate 40 is vertically arranged outside the side slab casting area 21, forming an L-shaped structure. At the connection between the two, the two right-angled sides of the isosceles right-angled triangular reinforcing plate 50 abut against and fix the first plate 30 and the second plate 40 respectively. When the pool body 100 is subjected to deformation caused by foundation settlement or temperature changes, the L-shaped structure resists torsion through overall stiffness, while the reinforcing plate 50 suppresses the cracking tendency at the corner through the stability of the triangular cross section, reducing the crack propagation caused by stress concentration, thereby reducing the risk of leakage.

[0045] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
