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.

(4) geotextiles has been held together bottom biomass pool, wrapped biomass pool spheroid equably, with adhesive tape, geotextiles top margin has been fixed on biomass pool housing;
(5) banket from bottom biomass pool, compacting;
(6) geotextiles top margin is left behind, level tears geotextiles, owing to being not easy compacting when banketing along circular arc-shaped bottom portion, has certain space in geotextiles and between banketing, can make to reserve space between geotextiles and global shell, and add sand equably in this space;
(7) geotextiles has been held together to wrap biomass pool spheroid, has been fixed on biomass pool housing with adhesive tape, again it is banketed, compacting work, the most whole biomass pool buries, completes 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 Woven geofabric or non-woven geotextile, and shape is circular.
The diameter of described geotextiles is that bottom biomass pool lower semisphere, arc length adds 70 ~ 100cm again.
In described step (1), the number of plies of geotextiles is 1 ~ 3 layer.
In described step (2), the thickness of sand is 5 ~ 7cm, and the tiling diameter of sand is 0.8 ~ 1.5m.
In described step (5), the height banketed is whole biomass pool height
In described step (6), adding of sand is highly whole biomass pool height
place, is consistent with the height banketed in step (5).
Space in described step (6) is 3 ~ 7mm.
Described sand is building yellow sand, and water content is 0.1 ~ 0.5%, and mud content is 0.1 ~ 0.2%, and 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 construction method, the mode taking this protective pad to add sand strengthens biomass pool polycrystalline substance, make biomass pool housing uniform stressed, the integral reinforcing effect served, simultaneously owing to using the geotextiles thicker compared with material, the effect of insulation can also be played to engineering plastic methane tank.
