Abstract
The invention belongs to the technical field of building construction and relates to a construction method of a protecting pad of a methane tank. The construction method comprises the following steps of: firstly, placing geotechnical cloth into a pit of the methane tank, and unfolding according to the shape of the pit; laying sand on the unfolded geotechnical cloth at the center of the pit of the methane tank; placing the engineering plastic methane tank into the pit; holding the geotechnical cloth along the bottom of the methane tank, uniformly coating a sphere of the methane tank, and fixing the top side of the geotechnical cloth on a shell of the methane tank through an adhesive tape; filling and ramming from the bottom of the methane tank; pulling down the top side of the geotechnical cloth, horizontally pulling the geotechnical cloth, and uniformly adding sand between the geotechnical cloth and the sphere shell; holding the geotechnical cloth to coat the sphere of the methane tank, fixing on the shell of the methane tank, filling, ramming and burying the whole methane tank. By adoption of the method of the protecting pad through adding the sand into the geotechnical cloth, the bottom structure of the methane tank is reinforced, so that the shell of the methane tank is uniformly stressed, thus a good integral reinforcement action is provided and the protecting pad has a thermal insulation effect on the engineering plastic methane tank.
Description
Technical field
The invention belongs to technical field of building construction, relate to a kind of job practices of biomass pool protective pad.
Background technology
Engineering plastic methane tank is a kind of marsh gas generator that the family, rural area is built with (family) biomass pool that is widely used in, and is to be formed by the compacting of the engineering plastics such as ABS, MODIFIED PP.Engineering plastic methane tank has light weight, carrying, the simple and easy and good advantages such as comprehensive mechanical property of installation.Compare with the biomass pool that cement is built, when mounted between, all have greatly improved on the maintenance cost, tightness.
If but the engineering plastic methane tank of rounded bottom directly contacts with earth, owing to when circular arc-shaped bottom portion bankets, be not easy compacting, loose and gap can appear in the earth of engineering plastic methane tank bottom periphery, therefore the part causes stress to concentrate at the bottom of the engineering plastic methane tank, can produce the danger of breaking in stressed concentrated situation.
Summary of the invention
The object of the invention is to provides a kind of biomass pool protective pad job practices for the defective of prior art.The biomass pool protective pad is between engineering plastic methane tank and bear between the earth of weight; form compound buffer layer by geotextiles, sand; the biomass pool protective pad is applied on the biomass pool; simple and convenient is installed; good effect and effect have been played improving the whole distribution of force of biomass pool, for the installation of biomass pool, use a kind of engineering plastic methane tank housing safeguard measure is provided.
A kind of biomass pool protective pad job practices comprises following steps:
(1) geotextiles is put into the hole of biomass pool, launched by the shape in hole;
(2) lay sand in the geotextiles of biomass pool hole center deployment;
(3) biomass pool is put into the hole, its bottom contacts with the sand of laying;
(4) geotextiles has been held together along the biomass pool bottom, wrapped equably the biomass pool spheroid, with adhesive tape the geotextiles top margin has been fixed on the biomass pool housing;
(5) begin to banket from biomass pool bottom, compacting;
(6) the geotextiles top margin is left behind, level is torn geotextiles, owing to be not easy compacting when circular arc-shaped bottom portion bankets, has certain space in geotextiles and between banketing, can make between geotextiles and the global shell and reserve the space, and in this space, add equably sand;
(7) geotextiles has been held together to wrap the biomass pool spheroid, has been fixed on the biomass pool housing with adhesive tape, again to its banket, compacting work, the most whole biomass pool buries, finishes the installation of biomass pool.
Described biomass pool is engineering plastic methane tank, preferred modified polypropene biomass pool or ABS (acrylonitrile-butadiene-styrene (ABS) plastics) biomass pool.
The material of described geotextiles is shaped as circle for spinning geotextiles or non-woven geotextile.
The diameter of described geotextiles is that biomass pool lower semisphere bottom arc length adds 70～100cm again.
In the described step (1), the number of plies of geotextiles is 1～3 layer.
In the described step (2), the thickness of sand is 5～7cm, and the tiling diameter of sand is 0.8～1.5m.
In the described step (5), the height that bankets is whole biomass pool height
In the described step (6), the adding of sand highly is whole biomass pool height
The place is consistent with the height that has banketed in the step (5).
Space in the described step (6) is 3～7mm.
Described sand is the building yellow sand, and water content is 0.1～0.5%, and mud content is 0.1～0.2%, and the sand particle diameter is 0.5～2mm.
Beneficial effect of the present invention:
The present invention relates to a kind of biomass pool protective pad job practices, the mode of taking this protective pad to add sand has been reinforced the biomass pool polycrystalline substance, make biomass pool housing uniform stressed, played good integral reinforcing effect, owing to use the geotextiles thicker than material, can also play to engineering plastic methane tank the effect of insulation simultaneously.
