Embodiment 1

[0018] A construction method of a prefabricated septic tank includes the following steps:

[0019] Step 1: Determine the construction location and the location of the inspection well according to the geological conditions and the size of the septic tank, and then determine the construction route and sequence;

[0020] Step 2. Leveling and cleaning the site according to the scope of construction requirements, excavating the foundation trench for septic tank installation, and constructing temporary facilities and construction channels at the same time;

[0021] Step 3: Mix the concrete and water according to the proportion, make the mixture wet after mixing, then level the bottom of the base tank, and then lay a gravel cushion on the bottom, and a concrete layer on the upper surface of the gravel cushion;

[0022] Step 4. Then build a septic tank frame on the surface of the concrete layer. The outer surface of the frame is fixed by a fixing frame. The frame is equipped with internal part...

Abstract

The invention discloses a construction method of a prefabricated septic tank. The construction method of the prefabricated septic tank comprises the following steps: determining a construction position and the position of an inspection well; carrying out field leveling cleaning, and excavating a foundation ditch for mounting a septic tank; mixing concrete with water in proportion, and then enabling the mixture to be in a wet state, leveling the bottom of the foundation ditch, laying a broken stone hardcore on the bottom, and laying a concrete layer on the upper surface of the broken stone hardcore; then building a frame of the septic tank on the surface of the concrete layer, and meanwhile prefabricating a cover plate; pouring prepared concrete into an inner partition plate of the frame, standing for 8-14 hours, and then sequentially disassembling a fixing rack, the frame and the inner partition plate; mounting a connecting pipeline according to a construction drawing, and covering theseptic tank with the cover plate after a water closing test is qualified; and carrying out sealing, earthwork backfilling and tamping, and finally checking. The construction method of the prefabricated septic tank is good in structural stability, high in seepage resistance, small in engineering quantity, short in period and convenient to construct, and mounting can be implemented along with excavation.

Description

Technical field [0001] The invention belongs to the technical field of building construction, and specifically relates to a construction method of a prefabricated septic tank. Background technique [0002] Septic tank is a kind of equipment for processing and distinguishing and filtering sediment. The principle is that the solidified substance decomposes at the bottom of the pool, and the upper layer of hydrated objects enters the pipeline and flows away, preventing the pipeline from being blocked and giving the solidified substance (feces and other garbage) sufficient time to hydrolyze. Septic tank refers to a small processing structure that separates and settles domestic sewage and anaerobic digestion of sludge. Most of the existing septic tank construction methods have long periods and often leaks. Therefore, a new type of prefabricated septic tank construction method is needed to solve the above problems and meet people's needs. Summary of the invention [0003] The purpose ...
