When a combination of fiberglass septic tanks installed base soil or groundwater and the soil is poor, Hanyang fiberglass septic tanks, thick gravel or crushed stone to shop 1OOmm compaction, set 1OOmm-300mmC1O level concrete pad on the base, concrete cushion capped 1OOmm sand cushion, tank tamped earth elements on both sides. After hoisting fiberglass septic tanks in compliance with the requirements, the pool must perfusion 1/3 water to stabilize, and then manually compacted. FRP tanks fourth stage of the product is mechanical winding fiberglass septic tanks, this product uses mechanical convex surface of the cylinder ends design, fiberglass septic tanks installed in Wuhan, cylinder mechanical winding process, high compressive design production, the product overall compression molding, impact resistance, strength and toughness factor of safety than the traditional hand lay fiberglass septic tanks increased several times, to make up for the traditional hand lay fiberglass septic tanks, corrugated fiberglass septic tank hand paste uneven thickness, manufacturing rough enough. FRP tanks in place after the situation backfill the lower pool surrounded by sand infill (height shall be not less than half the diameter of the cell body) prohibited the use of construction waste as a soil backfill, Wuhan fiberglass septic tanks wholesale, backfill the stones should be removed, backfill compaction should be layered, each 30mm were connected. Artificial compaction is appropriate, it should not be partial violently shocks (such as air-ram, etc.) backfill, backfill around the pond must be dense.
