Various process pools constructed with reinforced concrete have the following problems in engineering applications: Because various process pools constructed with reinforced concrete need to meet the requirements of impermeability and strength, they mostly adopt a thin shell dense reinforcement structure. High-energy-consuming building materials such as steel bars and cement are used in large quantities. Especially in the scenario of small sewage treatment stations, the process is complicated, the construction period is long, and the cost is high. It is difficult to effectively simplify the construction process, shorten the construction period and reduce the construction cost. Utility Model Content

[0004] The embodiment of the present utility model is implemented as follows: a thin-walled corrugated plate pool structure for sewage treatment includes a concrete foundation and further includes:

[0005] an annular groove, wherein the annular groove is opened on the concrete foundation;

[0006] Galvanized corrugated sheets, wherein the galvanized corrugated sheets are provided in plurality, each of which is provided with bolt holes, and adjacent galvanized corrugated sheets are stacked on each other and fixed by fastening bolts connecting the bolt holes, and the cross-section of the multiple galvanized corrugated sheets after assembly is formed into a ring; the galvanized corrugated sheets in the height direction are stacked one corrugation and connected by fastening bolts;

[0007] The assembled galvanized corrugated sheet forming the pool wall is installed in the annular groove and filled with micro-expansion concrete for secondary grouting.

[0008] The anti-seepage geomembrane is laid on the inner side of the pool wall and the surface of the concrete foundation, and is fixed on the top of the pool wall by flat steel strips and fastening bolts.

[0009] Preferably, the annular groove has a width of 100 mm and a depth of 50 mm.

[0010] Preferably, the galvanized corrugated sheet has a thickness of 1.5 mm and is cold-pressed into a corrugated shape by a dedicated molding device.

[0011] Preferably, the surfaces of the galvanized corrugated sheet and the fastening bolts are painted with epoxy coal tar paint.

[0012] The embodiment of the present invention provides a thin-walled corrugated plate pool structure for sewage treatment. The pool wall is formed by splicing a number of standard unit corrugated plate modules of the same size and connecting them by fastening bolts. The construction is simple and the construction technical difficulty is effectively reduced. The galvanized corrugated plate can be prefabricated in the factory and carried out simultaneously with the concrete foundation construction of the pool bottom, which greatly shortens the construction period. Except for the need to configure a concrete foundation for the pool bottom, the use of steel bars and cement is greatly reduced, and the workload involved in the construction of the steel-concrete structure, such as steel bar prefabrication, formwork support, concrete pouring and maintenance, is greatly reduced, and the construction cost is greatly reduced. The pool wall is easy to disassemble and assemble and can be recycled. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0021] like Figure 1-Figure 5The figure shows a structural diagram of a thin-walled corrugated plate pool structure for sewage treatment provided by an embodiment of the present invention, comprising a concrete foundation 1, an annular groove 2, a galvanized corrugated plate 3 and an anti-seepage geomembrane 5, wherein the annular groove 2 is opened on the concrete foundation 1; the galvanized corrugated plates 3 are provided in plurality, each of which is provided with a bolt hole 7, and adjacent galvanized corrugated plates 3 are superimposed on each other and fixed by connecting the bolt holes 7 with fastening bolts 4, and the cross-section of the multiple galvanized corrugated plates 3 after assembly is completed is a ring; the galvanized corrugated plates 3 in the height direction are superimposed with one corrugation and connected by fastening bolts 4; the surfaces of the galvanized corrugated plates 3 and the fastening bolts 4 are painted with epoxy coal tar paint; wherein the assembled galvanized corrugated plates 3 constitute the pool wall and are installed in the annular groove 2, and are filled by secondary grouting of micro-expansion concrete; the anti-seepage geomembrane 5 is paved on the inner side of the pool wall and the surface of the concrete foundation 1, and is fixed on the top of the pool wall by flat steel strips 6 and fastening bolts 7.

[0022] In one example of the present invention, during installation, it is necessary to determine the number of annular corrugated plates to be spliced ​​and the number of layers in the height direction according to the diameter and height dimensions of the circular pool, and then determine the bending radius, arc length, and width dimensions of a single galvanized corrugated plate 3. In order to facilitate the installation and splicing of the galvanized corrugated plate 3, the size of a single galvanized corrugated plate 3 is controlled to an arc length of no more than 4m and a width of no more than 1.5m.

[0023] like Figure 1 and Figure 2 As shown, as a preferred embodiment of the present invention, the annular groove 2 has a width of 100 mm and a depth of 50 mm.

[0024] In one embodiment of the present invention, the galvanized corrugated sheet 3 has a thickness of 1.5 mm and is cold-pressed into a corrugated shape by a dedicated molding device.

[0025] In summary, when using, the galvanized corrugated sheet 3 is formed and cut according to the required arc length and width dimensions, and threaded holes 7 are cold punched around the galvanized corrugated sheet 3 corresponding to the circumferential and longitudinal splicing positions. When the concrete foundation 1 reaches 75% or more of the design strength, the wall panels can be assembled on site. The upper and lower wall panels are constructed using the positive installation method, that is, they are assembled layer by layer from bottom to top. The reserved annular groove 2 must be cleaned and leveled before the galvanized corrugated sheet 3 is seated. When the two adjacent galvanized corrugated sheets 3 are connected by fastening bolts 4 in the direction of reversal and longitudinal direction, they should be The bolt connection pair is tightened according to the principle of "longitudinal first, then circumferential, left-right symmetry, and alternating jump holes". After the galvanized corrugated plate 3 is assembled, epoxy coal tar paint is used to paint the fastening bolts 4, the corners of the galvanized corrugated plate 3, and the scratched areas of the galvanized layer to achieve the purpose of corrosion protection. After the pool wall is assembled and positioned, the annular groove 2 is filled and cured with micro-expansive concrete for the second time. The anti-seepage geomembrane 5 is laid on the inner wall and bottom of the pool, and flat steel strips 6 are arranged at the corresponding positions on the outer wall of the pool top, which are fixed by fastening bolts 4.
