Assembly type pressure-resistant septic tank and assembly method thereof

Abstract

The invention discloses an assembly type pressure-resistant septic tank. The septic tank is cast in situ by precast slabs. The septic tank comprises three tank bottom precast slabs, two tank end precast slabs, two partition precast slabs and six tank side precast slabs; connecting heads are respectively arranged on four end faces of each of the tank bottom precast slabs; the connecting heads are respectively arranged on the lower end faces and the end faces on two sides of the tank bottom precast slabs and the tank side precast slabs; the connecting heads are arranged on the bottom end faces of the partition precast slabs; cross sections of the partition precast slabs are I-shaped; and double connecting heads are arranged on the end faces on the two sides of each of the partition precast slabs. The septic tank of a whole concrete structure is divided into a plurality of precast slab structures, and the precasting is performed before the cast-in-situ assembly, thereby greatly shorteningthe construction period of the septic tank, and reducing the construction difficulty; and compared with a plastic septic tank, the concrete septic tank is higher in pressure resistance and corrosionresistance, and is higher in sealing performance.

Description

technical field [0001] The invention belongs to the field of septic tanks, and more specifically relates to an assembled anti-pressure septic tank. Background technique [0002] Septic tanks are important in the construction of sanitary toilets in new rural areas. In the prior art, septic tanks mostly use injection-molded clinker structures. This kind of septic tank has high requirements on the environment. The area is difficult to use, and the septic tank is prone to displacement. At the same time, due to changes in the soil structure around the septic tank, the pressure on various parts of the septic tank is different, which can easily cause the septic tank to rupture under pressure. Contents of the invention [0003] The purpose of the present invention is to provide a prefabricated anti-pressure septic tank, change the septic tank in the prior art from the injection-molded plastic structure, and adopt a concrete structure, which greatly increases the ability of the sep...
