A kind of septic tank half mold integral molding method

Abstract

The invention proposes a method for integrally forming half molds for septic tanks, which includes an outer mold, an inner mold, a steel frame and a pressing plate, the pressing plate is provided with a pouring opening and a mold taking opening, the inner mold is an inflatable mandrel, and the outer mold is an inflatable mandrel. The mold is a cavity with an upper end opening. The molding method includes cleaning the surface of the mold, laying a steel skeleton inside the outer mold, placing an inflatable inner mold, covering the pressure plate, pouring concrete, hardening and demoulding, and the integrated septic tank half can be obtained. The overall preparation method is simple, the demoulding is easy, and it has good application prospects.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to a method for integrally forming half molds of a septic tank. Background technique [0002] With the advancement of urbanization, the reform of rural areas and the enhancement of environmental protection awareness, the demand for septic tanks is also increasing. At present, common septic tanks are mainly divided into reinforced concrete septic tanks and glass fiber reinforced plastic septic tanks. Steel septic tank has the advantages of simple structure, light weight, large capacity, etc., but its installation is cumbersome, needs protection, and has low pressure bearing performance. Reinforced concrete septic tank has good mechanical strength and service life, and its installation is convenient. There is no need for additional protective measures, and it can be dug and buried now, but its airtightness is relatively poor, and the preparation process of the reinf...

[0002] With the advancement of urbanization, the reform of rural areas and the enhancement of environmental protection awareness, the demand for septic tanks is also increasing. At present, common septic tanks are mainly divided into reinforced concrete septic tanks and glass fiber reinforced plastic septic tanks. Steel septic tank has the advantages of simple structure, light weight, large capacity, etc., but its installation is cumbersome, needs protection, and has low pressure bearing performance. Reinforced concrete septic tank has good mechanical strength and service life, and its installation is convenient. There is no need for additional protective measures, and it can be dug and buried now, but its airtightness is relatively poor, and the preparation process of reinforced concrete structures is cumbersome and the preparation period is long

[0003] At present, the common concrete septic tanks are mostly produced in a split type. The inner mold and the outer mold are combined to form the pouring cavity of the septic tank half-mold. However, the density of the concrete is relatively high. In order to ensure that the mold does not deform during the pouring process, strength is required. For taller molds, casting molds formed by welding steel plates are mostly used at present, so the pouring molds are heavy and need to rely on lifting equipment to move the molds. This not only increases the difficulty of production, but also reduces the efficiency of production, and the weight And larger molds will also have a greater impact on the safety management of the production process
