Problems solved by technology

Its main structure is all made of brick structure, plain concrete or micro-reinforced concrete. The geometric shape and size are restricted by the strength of the structural material, so the integrity is weak, and the durability, safety and reliability are poor. The on-site construction period is too long and the construction quality is difficult. Guarantee, directly affect the further popularization and application in the vast rural areas

Embodiment 1

[0022] The assembly steps of the present invention are as follows:

[0023] (1) Lay extruded boards with a certain compressive strength at the pre-installation position;

[0024] (2) Use cast-in-place concrete on the extruded plastic board or use prefabricated steel wire mesh cement to assemble on site in sections to form the bottom plate;

[0025] (3) Through the staggered butt joint of the reserved rings on the four sides of the bottom plate and the reserved rings on the side plates, the joints of the bottom plate are interspersed, and the seams are treated with high-grade cement mortar, and the templates are used The reliable fixing and high-frequency vibration ensure the compactness of the mortar at the joint.

[0026] (4) The side panels and side panels are directly staggered through the reserved rings and then interspersed with ribs. The resulting side panel joints are treated with high-grade cement mortar, and through reliable fixation and high-frequency vibration of t...

Embodiment 2

[0033] The present invention is combined with the aerobic filter tank as the assembly steps of the community sewage treatment tank as follows:

[0034] (1) Lay extruded boards with a certain compressive strength at the pre-installation position;

[0035] (2) Use cast-in-place concrete on the extruded plastic board or use prefabricated steel wire mesh cement to assemble on site in sections to form the bottom plate;

[0036] (3) Through the staggered butt joint of the reserved rings on the four sides of the bottom plate and the reserved rings on the side plates, the joints of the bottom plate are interspersed, and the seams are treated with high-grade cement mortar, and the templates are used The reliable fixing and high-frequency vibration ensure the compactness of the mortar at the joint.

[0037] (4) The side panels and side panels are directly staggered through the reserved rings and then interspersed with ribs. The resulting side panel joints are treated with high-grade ce...

Abstract

The invention relates to a ferrocement biogas digester which is a box-shaped structure body formed by the splicing of a plurality of ferrocement panels; the biogas digester comprises an acidification feeding pool, a feeding room, a fermentation pool, a discharging pool and a water pressure room, which are connected and communicated in sequence; and the upper surface of the fermentation pool is provided with a manhole cover which is provided with an air outlet pipe. The invention has the advantages of good integrity, high local strength, strong compactness and impermeability, high safety and reliability, and effectively enhances the durability of the main structure in a corrosive medium; simultaneously, the invention also has short on-site construction period and less processes with high technical requirements, can be effectively controlled in the construction scope, and avoids the defects of easy omission when in large-scale construction.

Description

Technical field: [0001] The invention relates to a biogas digester, in particular to a steel mesh cement biogas digester. Background technique: [0002] After years of practice, the underground water pressure biogas digester is the main type of pond that is popularized and applied in rural areas in my country. my country has formulated the "Standard Atlas of Household Biogas Digesters" (GB / T4750-2002). According to national standards, the types of rural household biogas digesters in my country include meandering cloth biogas digesters, prefabricated reinforced concrete slab biogas digesters, cylindrical biogas digesters, oval biogas digesters, and separated floating cover biogas digesters. Its main structure is all made of brick structure, plain concrete or micro-reinforced concrete. The geometric shape and size are restricted by the strength of the structural material, so the integrity is weak, and the durability, safety and reliability are poor. The on-site construction pe...
