Construction method of special-shaped wall in double-layer secondary settling tank

Abstract

The invention relates to a double-layer secondary sedimentation tank special-shaped wall construction method. The method includes the following construction steps of firstly, conducting measurement and pay-off; secondly, erecting a formwork body, wherein the step includes the substeps that a, bottom plate reinforcing steel bars are bound, and oblique opposite-pull threaded rods are distributed; b, bottom plate concrete is poured on the bottom plate reinforcing steel bars, and special-shaped wall control lines are ejected on the bottom plate; c, vertical formworks are distributed, and horizontal opposite-pull threaded rods are arranged between the vertical formworks; d, oblique formworks are installed, and horizontal wood lumps are arranged at the upper ends of inclined wood lumps; e, horizontal angle iron is arranged, and the two ends of the horizontal angle iron are connected with the horizontal wood lumps respectively; thirdly, binding reinforcing steel bars in the formwork body; fourthly, pouring concrete in the formwork body, detaching the formwork body, and forming a special-shaped wall. By uniform arrangement of the formworks, the construction cost is reduced, the erecting speed of the formwork body is increased, the erecting difficulty of the formwork body is lowered, and the problem that the deformation body deforms or moves is avoided.

Description

technical field [0001] The invention relates to the technical field of special-shaped walls of double-layer secondary settling tanks, in particular to a construction method of special-shaped walls of double-layer secondary settling tanks. Background technique [0002] After the 1950s, the global population grew rapidly, the industry developed rapidly, the global water resource situation deteriorated rapidly, and the "water crisis" became increasingly serious. Among them, human's demand for water resources is expanding at an alarming rate, and the increasingly serious water pollution erodes a large amount of water resources available for consumption. China's per capita water resources are small and the spatial distribution is uneven. With the acceleration of urbanization and industrialization in China, the demand gap for water resources is also increasing. In this context, the sewage treatment industry has become a new industry. [0003] Under the guidance of the concept o...

Problems solved by technology

[0005] The object of the present invention is to provide a double-layer secondary settling tank special-shaped wall construction method, aiming to solve the difficulty in building the formwork body and difficult positioning of the formwork body during the construction process of the double-layer secondary settling tank special-shaped wall body in the prior art. When concrete is used, the formwork body is prone to deformation and displacement problems
