Construction method of glass reinforced plastic septic tank

Abstract

The invention relates to a construction method of a glass reinforced plastic septic tank. The construction method comprises excavating a foundation pit and reserving an excavation margin, removing theexcavation margin by manual excavation, cleaning and flattening the bottom wall and the side wall of the foundation pit, paving construction cushion layers on the bottom wall and the side wall of thefoundation pit, hoisting glass reinforced plastic and paving an anti-corrosion layer on the surface of the glass reinforced plastic. By adopting the technical scheme of the invention, when the foundation pit is excavated, a two-step method is used for excavation; by setting the corresponding excavation margin, the contour shape of the foundation pit is easy to control and is tightly fitted to thesurface of the glass reinforced plastic; the glass reinforced plastic is bonded to the bottom wall and side wall of the foundation pit through the construction cushion layers, and the anti-corrosionlayer is paved on the surface of the glass reinforced plastic. The construction method is favorable for industrial production and convenient to mount; the glass reinforced plastic is firmly installed,so that the overall structural strength and carrying capacity of the septic tank are enhanced. Meanwhile, construction cushion layers and the anti-corrosion layer enhance the sealing effect of the septic tank, avoid pollution caused by exposure of excrements and allow the septic tank to have longer service life.

Description

technical field [0001] The invention belongs to the technical field of septic tanks, in particular to a method for constructing a glass reinforced plastic septic tank. Background technique [0002] Traditional brick and reinforced concrete septic tanks have poor corrosion resistance, long on-site construction period, poor treatment effect, high cost, easy to leak, and occupy a large area. At present, there are plastic septic tanks on the market. This kind of septic tank has strong corrosion resistance and can be industrialized. However, whether it is a brick, reinforced concrete structure or plastic structure, the septic tank mainly releases and intercepts the feces. After natural aging, only relying on its own anaerobic bacteria to react in the anaerobic layer at the bottom of the pool, the contact between the anaerobic bacteria and the feces in the sewage is not sufficient, so there is still a large amount of feces in the discharged water. Discharge into rivers to pollute...

[0002] Traditional brick and reinforced concrete septic tanks have poor corrosion resistance, long on-site construction period, poor treatment effect, high cost, easy to leak, and occupy a large area

At present, there are plastic septic tanks on the market. This kind of septic tank has strong corrosion resistance and can be industrialized. However, whether it is a brick, reinforced concrete structure or plastic structure, the septic tank mainly releases and intercepts the feces. After natural aging, only relying on its own anaerobic bacteria to react in the anaerobic layer at the bottom of the pool, the contact between the anaerobic bacteria and the feces in the sewage is not sufficient, so there is still a large amount of feces in the discharged water. Discharge into rivers to pollute water quality

FRP septic tanks are also used in the prior art, but most of the FRP are connected by bolts during installation. With the prolongation of use time, the bolts are prone to aging and rusting, causing septic tanks to leak and causing environmental pollution
