TECHNICAL FIELD
[0001] The utility model relates to the technical field of deformation joint leakage treatment, especially to a large pool body deformation joint leakage treatment structure. BACKGROUND
[0002] Large urban sewage treatment plants mostly adopt reinforced concrete structures, which become the first choice of materials due to their high bearing capacity, good moldability and durability. However, reinforced concrete structures also have the disadvantages of high brittleness and poor crack resistance. In order to avoid structural deformation and cracking caused by uneven settlement of the foundation, deformation joints need to be set at appropriate positions during design.
[0003] Since the pool body is mostly a thin-walled structure, the deformation joint not only needs to meet the deformation requirement, but also needs to have anti-seepage and crack resistance, and the construction process is complex. During construction, external environmental factors such as temperature and foundation deformation, as well as human factors such as narrow operation space and construction personnel's technology, can all affect the construction quality and cause leakage of the deformation joint. The leakage problem not only affects the appearance and environmental quality of the pool body, but also may shorten the service life of the pool body and threaten the safety of the structure. Therefore, ensuring the construction quality of the deformation joint is crucial for the long-term stable operation of the sewage treatment plant. SUMMARY

The structure has durability, corrosion resistance and anti-seismic deformation ability. It is convenient to process and install on site, has wide application range, and the construction quality is controllable, which avoids repeated treatment of deformation joint leakage and resource waste, and significantly improves the construction efficiency and economy.

The bottom of the asphalt hemp is in contact with the water stop belt of the original water stop structure. The joint opening and the part above the ground of the deformation joint are blocked by the SR plastic fillers. The bottom of the SR plastic fillers is in contact with the top of the water-swelling sealing strips. The EPDM SR cover sheets are wrapped outside the SR plastic fillers, and their two sides are fixed to the ground by fixing members.
[0008] Further, the asphalt hemp, the water-swelling sealing strips, the SR plastic fillers and the EPDM SR cover sheets are arranged along the deformation joint to fill the entire deformation joint.

[0015] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings of the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.
[0016] In view of the problems that the traditional deformation joint leakage treatment meets the deformation function but cannot achieve the plugging effect, achieves the plugging effect but does not meet the deformation requirement, and both cannot be considered, the embodiment provides a large pool body deformation joint leakage treatment structure. Figure 1As shown, the large pool body deformation joint leakage treatment structure includes asphalt hemp 7, water-swelling sealing strip 6, SR plastic filler 5, and EPDM SR cover sheet 1 installed above the original deformation joint sealing structure; the original sealing structure includes polyethylene foam board 9 laid at the bottom of the deformation joint, and rubber sealing tape 8.
[0017] Specifically, the asphalt hemp 7 and the water-swelling sealing strip 6 are both located in the deformation joint, and the water-swelling sealing strip is located above the asphalt hemp 7, and the bottom of the asphalt hemp 7 is in contact with the sealing tape 8 of the original sealing structure; the water-swelling sealing strip 6 has a specification of PZ-400, 40*30mm, and has a high expansion rate and tensile strength; the asphalt hemp 7 has good corrosion resistance and good durability.
[0018] The deformation joint gap and the part above the ground are blocked by the SR plastic filler 5, and the bottom of the SR plastic filler 5 is in contact with the top of the water-swelling sealing strip 6; the SR plastic filler 5 is a high-performance nano caulking sealing material, which has high impermeability, ductility and adhesion, and at the same time, the material has high heat resistance and corrosion resistance.
[0019] The EPDM SR cover sheet 1 is wrapped outside the SR plastic filler 5, and its two sides are fixed to the ground through fixing members; the EPDM SR cover sheet 1 is made of chemically synthesized rubber, which is first in contact with water, has high oxidation resistance, ozone resistance and corrosion resistance, and has a certain deformation ability to ensure the deformation requirement of the main structure.
[0020] As shown in Figure 1 The asphalt hemp 7, the water-swelling sealing strip 6, the SR plastic filler 5, and the EPDM SR cover sheet 1 in the embodiment are laid along the deformation joint and fill the entire deformation joint; a strong waterproof barrier is formed by the SR plastic filler 5 cooperating with the EPDM SR cover sheet 1, which effectively improves the service life of the deformation joint after leakage treatment; the water-swelling sealing strip 6 cooperates with the asphalt hemp 7 to form the main caulking material of the large pool body deformation joint leakage treatment structure, and the two together form a second waterproof and leakage blocking barrier, mainly to prevent the small amount of water leaked from the first waterproof barrier from continuing to infiltrate, achieving the effect of double insurance of waterproof and leakage blocking.
[0021] Further, as shown in Figure 1As shown, the ternary EPDM SR cover sheet 1 in this embodiment is provided with two groups of fixing members on both sides thereof with the deformation joint as the center. The fixing members include a pressing sheet 2 and a plurality of expansion bolts 3. The pressing sheet 2 is parallel to the deformation joint and is located above both sides of the ternary EPDM SR cover sheet 1. The pressing sheet 2 is pre-punched according to the arrangement interval of the expansion bolts 3, and the hole interval is 300 mm. The expansion bolts 3 are sequentially inserted into the ground through the pressing sheet 2 and the ternary EPDM SR cover sheet 1. The combination of the pressing sheet 2 and the expansion bolts 3 effectively fixes the ternary EPDM SR cover sheet 1, improves the structural deformation resistance of the treatment structure, and ensures the leakage treatment effect.
[0022] In addition, in order to further ensure the leakage treatment effect, as shown in the drawings, Figure 1 As shown, the ternary EPDM SR cover sheet 1 in this embodiment is provided with two groups of fixing members on both sides thereof with the deformation joint as the center. The fixing members include a pressing sheet 2 and a plurality of expansion bolts 3. The pressing sheet 2 is parallel to the deformation joint and is located above both sides of the ternary EPDM SR cover sheet 1. The pressing sheet 2 is pre-punched according to the arrangement interval of the expansion bolts 3, and the hole interval is 300 mm. The expansion bolts 3 are sequentially inserted into the ground through the pressing sheet 2 and the ternary EPDM SR cover sheet 1. The combination of the pressing sheet 2 and the expansion bolts 3 effectively fixes the ternary EPDM SR cover sheet 1, improves the structural deformation resistance of the treatment structure, and ensures the leakage treatment effect.
[0023] The use process of the large pool body deformation joint leakage treatment structure is as follows:
[0024] When the structural deformation joint appears leakage phenomenon, first, the leakage position is marked, the original caulking material in the deformation joint is removed according to the marked position after the water in the structure is drained, and then a V-shaped notch is cut on both sides of the upper opening of the deformation joint by using a handheld electric cutter, so as to facilitate the subsequent installation and filling of the SR plastic filler 5. After cutting, holes are drilled on both sides of the deformation joint according to the hole arrangement interval on the pressing sheet 2, so as to facilitate the subsequent installation and fixing of the pressing sheet 2 and the expansion bolts 3. After cutting and drilling, the working surface is blown by using a high-pressure air blower, and if necessary, it is cleaned by using a high-pressure water gun; after cleaning, the working surface is dried to ensure that the working surface is dry.
[0025] Then, the asphalt hemp 7 and the water-swelling waterstop 6 are sequentially filled in the deformation joint to the V-shaped notch, and the working surface is cleaned again to ensure that the working surface is dry and clean. The SR plastic filler 5 is formed according to the shape of the notch, and is installed and filled above the V-shaped notch. In order to ensure that the ternary EPDM SR cover sheet 1 and the SR plastic filler 5 are closely combined, the SR plastic filler 5 is processed into an arched structure during installation. After the SR plastic filler 5 is installed in place, the surface film is torn off, the ternary EPDM SR cover sheet 1 is pasted above the SR plastic filler 5, and the pressing sheet 2 and the expansion bolts 3 on both sides of the ternary EPDM SR cover sheet 1 are effectively connected with the bolt holes on both sides of the deformation joint.
[0026] Finally, the three-EP SR cover sheet 1 and the structure contact surface, the sheet 2 and the expansion bolt 3 around the gap are sealed by coating the layer 4 of the leak-stopping material, further ensuring the effect of the deformation joint leakage treatment. Thus, the construction of the deformation joint leakage treatment structure is completed, the whole structure not only meets the seismic deformation function of the main structure, but also achieves the anti-seepage and leak-stopping effect, overcomes the problem that the two cannot be considered, effectively reduces the frequency of repeated repair of the deformation joint leakage, saves the maintenance cost, and ensures the structure use function and service life.
