Formal construction 1, the septic tank below precipitate the packing process, the use of electric lift device Masui Hubei fiberglass septic model, and then placed in a sealed carts Sinotrans (This ensures that health issues section of the construction site and Sinotrans) . 2, workers go down operations must be replaced every two hours (cycle operation). 3, clean up criteria: water without floating debris, wall basic cleaning, jobsite basic sanitation. 4, Sinotrans requirements: to produce daily garbage bags, transported from the construction site in Hubei fiberglass septic quotas were consumptive. Features: 1, overall equipment manufacturing, good sealing, no leakage fiberglass septic tanks thoroughly to prevent contamination due to underground brick masonry and concrete septic tank seepage generated will help to improve the wet ground due to leakage caused soft sinking to prevent harm to the surrounding buildings. Construction on the building tower coal mine subsidence area more suitable. 2, high biological efficiency, small footprint, saving land resources. 3, light equipment weight, easy installation and construction, easy to transport, help to improve construction efficiency. 4, the device is lower than the overall cost of reinforced concrete septic tanks, septic tanks and brick and concrete cost flat. 5, long life, high compressive strength, resistance to moisture, oxidation, afraid of acid, the normal life of more than 50 years.
