Air mold pouring polymerization concrete air inflation detection type small water cellar, construction method of small water cellar, application of small water cellar in biogas digester construction and inflatable model special for small water cellar

Abstract

The invention relates to a small water cellar, a construction method of the small water cellar, the application of the small water cellar in biogas digester construction and an air mold special for the small water cellar. A regular splay air sealing port is formed in the position where a concrete cellar body is connected with a cellar mouth, the regular splay air sealing port is sealed with a detachable air sealing pot, and a concave dredging pit which is used for converging sludge at the bottom and cleaning the sludge conveniently is reserved at the bottom of the concrete cellar body. Pouring is achieved by means of the cylindrical air mold, and the problems that when an ordinary steel or wood mold concrete pouring method is used, the amount of transported concrete is large, and a large amount of time and a large amount of labor are consumed for mold installation and dismantling are effectively solved; the bottom of the concrete cellar body is a plane, a circle of anti-floating ring is placed on the lower middle portion of the pit, mortar is prevented from flowing to the bottom of the concrete cellar body to generate buoyancy force, the problem of floating of the air mold is solved, and the problem that the bottom of the spherical air mold is difficult to place stably is solved; due to the fact that pouring is carried out on the upper wall and the top of the concrete cellar body and then pouring is carried out on the bottom of the concrete cellar body, the problem of unsafe top construction of the cellar is solved; due to the fact that the regular splay air sealing port is formed in the position of the cellar mouth, accuracy of detection of the airtightness of the small water cellar is improved.

Description

[0001] technical field [0002] The invention relates to a small water cellar, a construction method, an application in the construction of a methane pool, and a special air model. Background technique [0003] Most of the current small water cellars use steel molds, wooden molds or spherical air molds to pour ordinary concrete. The method of pouring ordinary concrete with steel molds and wooden molds has a large transportation volume, especially in mountainous areas with inconvenient transportation. It is labor-intensive and time-consuming to disassemble the mold; during the construction of the spherical or ellipsoidal air mold, with the continuous pouring of cement mortar, buoyancy will be generated from the bottom to the top to lift the air mold upwards, making the construction more difficult. The inner wall of the cellar is a hyperboloid or a round concave bottom, which not only makes it difficult for construction workers to stand upright, but also makes it difficult to ...

Problems solved by technology

[0003] Most of the current small water cellars use steel molds, wooden molds or spherical air molds to pour ordinary concrete. The method of pouring ordinary concrete with steel molds and wooden molds has a large transportation volume, especially in mountainous areas with inconvenient transportation. It is labor-intensive and time-consuming to disassemble the mold; during the construction of the spherical or ellipsoidal air mold, with the continuous pouring of cement mortar, buoyancy will be generated from the bottom to the top to lift the air mold upwards, making the construction more difficult. The inner wall of the cellar is a hyperboloid or a round concave bottom, which not only makes it difficult for construction workers to stand upright, but also makes it difficult to wipe the surface; after the traditional small water cellar is built, there is no means of testing the airtightness, and it is not easy to find water leakage in time. It is necessary to drain the water first before repairing. After the repair is completed, it has to wait for the rainy season to store water for re-inspection, or even wait until the next year or longer for the rainy season to fill in the water. The due economic and social benefits have not been brought into play in time.
