Problems solved by technology

Concrete generally has advantages in cost and performance over brickwork, but it is very laborious and troublesome to erect the internal steel formwork and wooden formwork of the pouring tank; multi-layer airbags are used as molds to pour concrete, because the multi-layer airbags are covered with steel mesh and attached with auxiliary membranes , often rely on the cooperation with the external formwork for construction, but the production, transportation and installation of the formwork are very troublesome, and the production of multi-layer airbags is difficult and the cost is high; during the construction process, the mutual displacement between the external formwork and the multi-layer airbags is easy Inconsistent wall thickness of the cellar will affect the construction efficiency and quality of the cellar

Abstract

The invention discloses a mould for building a spherical or cylindrical cellar and a method for building the cellar by the adoption of the mould. The mould comprises an air bag and an inflation and deflation device fixed on the air bag, wherein the air bag (1) is designed to be spherical or cylindrical and is made of one layer of soft material, a bag cap (1.4) is connected with the top end of the air bag (1), and the inflation and deflation device (2) is arranged on the bag cap (1.4) and is composed of an inflation and deflation pipe (3), an intercalated disc (4) fixed to the lower section of the inflation and deflation pipe (3) and a valve (5) arranged on the inflation and deflation pipe (3). The mould is simple in structure, low in production cost and stable and reliable in construction, and the construction method is simple, easy to operate, and high in construction efficiency.

Description

technical field [0001] The invention relates to the construction of cellars, in particular to the technical field of construction methods for spherical cellars. Background technique [0002] At present, with the development of my country's rural water conservancy construction and rural industrialization, containers such as cellars, underground cisterns, biogas digesters, and fruit and vegetable storage pits are in great demand. Typically, these cellars rely on brickwork, concrete steel formwork and multiple layers of air pockets as formcast concrete. Concrete generally has advantages in cost and performance over brickwork, but it is very laborious and troublesome to erect the internal steel formwork and wooden formwork of the pouring tank; multi-layer airbags are used as molds to pour concrete, because the multi-layer airbags are covered with steel mesh and attached with auxiliary membranes , often rely on the cooperation with the external formwork for construction, but the...
