Description

Technical Field

[0001] The utility model relates to the technical field of anti-corrosion, in particular to a device for anti-corrosion of a pool body. Background Art

[0002] At present, reinforced concrete tanks are mostly used to store sewage and wastewater. Since some sewage contains acid / alkali / salt components, ordinary reinforced concrete tanks are easily corroded and their lifespan is shortened. In order to prevent the structure of the reinforced concrete tank from being corroded by sewage, anti-corrosion treatment is generally performed on the surface of the side in contact with the water body. There are many ways to prevent corrosion, such as painting fiberglass / asphalt paint / anti-corrosion PE film, etc. The main problems encountered in current projects are the difficulty of secondary construction and the poor adhesion and easy fall-off of the anti-corrosion layer.

[0003] Among them, PE film is a high-quality anti-corrosion material with low price and long life. The film material has the characteristics of good flexibility, weldability, bendability and easy handling at the opening, and is deeply loved by the public. In order to solve the adhesion ability of PE film, the existing utility model patent with patent publication number CN116201224A discloses a multi-point anchoring PE board anti-corrosion structure and its application in sewage engineering, proposes a PE film structure with multiple anchoring points, and uses chains and steel nails to fix the PE film on the pool wall, but after the pool wall is poured, the secondary construction is completed, the external material has many fixing points, it is difficult to nail it in, the steel nail anchoring strength is small, the bonding strength is not strong enough, the chain is easy to fall off from the ring gap, and there are also problems such as long repeated construction cycle. And the existing utility model patent with patent publication number CN116591295A discloses a construction method for the anti-corrosion layer in the sewage treatment pool based on multi-point anchoring PE board, which discloses the technology of fixing the PE film with V-shaped anchor bars on one side with a template and pouring the pool body. Compared with CN116201224A, the construction speed is fast, but the V-shaped anchor structure on the surface of the PE membrane cannot enter the structural layer (blocked by steel bars), the fixed depth in the protective layer is small, the adhesion strength is low, and it is easier to fall off. Therefore, it is urgent to propose a stable and non-falling anti-corrosion structure. Utility Model Content

[0004] The main purpose of the utility model is to provide a device for anti-corrosion of a pool body, aiming to solve the technical problem that the existing anti-corrosion structure of the pool body is not firm and is easy to fall off.

[0037] See also Figure 1-8 , is a structural schematic diagram of an embodiment corresponding to a device for anti-corrosion of a pool body of the utility model, the device comprising an anti-corrosion layer 1 and a plurality of inner embedded parts 3 connecting the anti-corrosion layer 1 and the pool body 2; wherein, the anti-corrosion layer 1 comprises a bottom film layer 101, and a plurality of anchoring protrusions 102 arranged on the surface of the bottom film layer 101, the bottom film layer 101 is arranged on a side close to the inner wall of the pool body 2, and the cavity formed by the inner wall of the pool body 2 is used to fill the pool body 2 with water; one end of each inner embedded part 3 is connected to the corresponding anchoring protrusion 102, and the other end is embedded and fixed in the corresponding area inside the pool body 2. In specific applications, the anti-corrosion layer 1 is made of PE, and adjacent anti-corrosion layers are connected by welding through plane seams, corners, and openings, and then effectively covered on the inner wall surface of the pool body 2 through the bottom membrane layer 101, and the anti-corrosion layer 1 is effectively fixed to the inside of the pool body through the internal embedded parts 3, thereby enhancing the adhesion strength of the anti-corrosion layer and preventing the anti-corrosion layer from falling off, thereby achieving efficient anti-corrosion protection for the inside of the pool body 2. In addition, based on the softness of the anti-corrosion structural material and its strong ability to fit the pool wall, it is not prone to tearing even under higher water depth and water pressure conditions.

[0038] Furthermore, in the actual construction process, the anti-corrosion layer 1 and the pool body 2 are constructed as one body, and the ratio of each inner embedded part 3 embedded in the pool body 2 is 10%-100%, thereby enhancing the connection strength between the inner embedded parts 3 and the corresponding anchoring protrusions, reducing the work process of construction first and then anti-corrosion, and improving work efficiency.

[0039] Further, in Figure 1-5 In the embodiment shown, each anchoring protrusion 102 has a thick top and a thin bottom, and each inner embedded part 3 has at least one first through hole structure for a hanging hole, and each first through hole structure matches the top of the corresponding anchoring protrusion 102, such as Figure 3 As shown; and the anchoring protrusion 102 and the bottom membrane layer 101 are made of the same material and are an integrally formed structure, thereby enhancing the connection effect between the anti-corrosion layer and the inner embedded parts.

[0040] Preferably, the height of each anchoring protrusion 102 is set to 3 mm-30 mm, so as to facilitate the internal embedded component 3 to be effectively hung on the corresponding anchoring protrusion 102.

[0041] Furthermore, if Figure 4-5 As shown, each inner embedded part 3 includes a vertical portion 301 and a horizontal portion 302 connected to the inside of the tank body. Preferably, the vertical portion 301 and the horizontal portion 302 are L-shaped structures, and each first through hole structure is arranged on the corresponding vertical portion 301. Figure 4 In the embodiment shown, each inner embedded part 3 has a first through hole structure for a hanging hole, and thus the inner embedded part 3 in this embodiment is a single hanging hole structure, thereby achieving connection between the anti-corrosion layer and the inner embedded part; and Figure 5 In the illustrated embodiment, each inner embedded component 3 has two first through hole structures for hanging holes, and thus the inner embedded component 3 in this embodiment is a double hanging hole structure, so that while achieving the connection between the anti-corrosion layer and the inner embedded component, the stability of the connection between the anti-corrosion layer and the inner embedded component can also be improved.

[0042] In addition, two or more first through hole structures can be provided on the vertical portion 301 according to actual needs, and the spacing between adjacent first through hole structures matches the spacing between correspondingly connected anchoring protrusions 102, thereby improving the stability of the connection between the anti-corrosion layer and the inner embedded parts.

[0043] Furthermore, a second through hole structure for material penetration is also provided on the horizontal portion 302, thereby effectively avoiding the situation where the slurry cannot effectively penetrate the horizontal portion 302 during the integrated construction of the anti-corrosion layer 1 and the pool body 2, thereby improving the integrated construction efficiency of the anti-corrosion layer 1 and the pool body 2.

[0044] Further, in Figure 6-8In the illustrated embodiment, each anchoring protrusion 102 is provided with a third through hole structure for one end of the inner embedded component 3 to pass through, and the end of the inner embedded component 3 is hook-shaped, so as to hook the third through hole structure of the anchoring protrusion 102 and achieve the fixing effect of the anchoring protrusion 102 and the inner embedded component 3. Preferably, the other end of the inner embedded component 3 matching the third through hole structure can also be hook-shaped and connected to the steel bar 5 inside the tank body 2. In the actual construction process, the fixing strength and stability of the inner embedded component 3 and the corresponding anchoring protrusion 102 can be effectively enhanced.

[0045] Furthermore, if Figure 2 As shown in FIG. 7 , the center spacing between adjacent anchoring protrusions 102 is set to 5 mm-500 mm, and different center spacings between anchoring protrusions can be set for different anti-corrosion treatments of the tank body.

[0046] Furthermore, the spacing between adjacent inner embedded parts 103 can be set to 80mm-800mm according to the ratio of the inner embedded parts 103 to the inner part of the tank body 2. This effectively improves the stability between the inner embedded parts 103 and the tank body 2. In practical applications, the greater the ratio of the inner embedded parts 103 embedded in the tank body, the greater the tensile strength of the inner embedded parts 103, and the number of connections between the inner embedded parts 103 and the anchoring protrusions 102 can be reduced when the strength of the inner embedded parts 103 is increased. Preferably, each inner embedded part 3 is a metal structure and is a standard prefabricated part.

[0047] Furthermore, during the installation of the above device, auxiliary parts for assisting the fixing of the anticorrosion layer 1 and the pool body 2 need to be provided; the auxiliary parts include an inner template 6 provided on the surface of the bottom membrane layer 101, an outer template 7 provided on the outer wall surface of the pool body 2, and a tension screw 4 that can adjustably connect the inner template 6 and the inner template 7, and the inner template 6 is provided on the surface of the bottom membrane layer 101 away from the anchoring protrusion. The inner and outer templates 6, 7 and the tension screw 4 need to be removed after construction, the main body of the screw is cast in the pool and cannot be taken out, and the tail end of the screw exposed to the wall is cut off, and the hole where the screw passes through the anticorrosion layer 1 is sealed by patch welding.

[0048] In the above embodiments, those skilled in the art may adopt the existing technology for software control. The present utility model only protects the structure of the device for anti-corrosion of the pool body and the mutual connection relationship.

All equivalent structural changes made by using the contents of the present invention specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present invention.
