With the slurry management system of the present embodiment, analysis is made from the time required for treatment, the cost reduction, and the effect achieved: pile foundation construction is divided into water operation and land operation according to the slurry making quantity, the water operation is carried out, the height of the top surface of a pile foundation is generally below the water level and above the surface of a riverbed, the water depth is 1-2 m to 10m, the platform height is 3m to 4m, the pile length of the existing design pile is 20m, the whole process of pore forming needs to be 2 times, namely the (20 + 4) × 2 × 0.9 × 0.9 × 3.14=122 square. Calculated as 1.2 t/cube, has a weight of 122 x 1.2=146.4 t. The hole cleaning time is 3 days of treatment according to the conditions before pouring, and the time is increased by at least 2 days due to limited space of overwater operation. If the pile slag is not recycled, a crane is needed in the period, the slag car processes 20m pile slag, the pile slag is transported in a square of 0.9 multiplied by 3.14 multiplied by 20=50, and the outward transportation cost is generated according to the market price.
The mud subjected to the purification and precipitation treatment has the hardened and concrete-polluted parts removed, and about 80 percent of mud can be recycled. The remaining part needs to be transported outside the mud truck, 146.4 × 20% =29.28t, about 29.28/1.2=24.4 square, and if the treatment can be carried out in time, the floating slurry of the cast concrete flows into the mud pit.
If 80% of the slurry is wasted, the soil needs to be transported again for slurry making, the slurry making quality needs to see whether the quality of the slurry making soil is good, calculated by the good quality soil, 146.4 x (1.2-1) =29.28t, the soil is generally converted by about 50%, the slurry needs to be transported in 60t of soil, the slurry making time is 2 days, the time for cleaning a slurry pool needs 1.5 days, and the additional 3.5 days are wasted. And in the construction process, if the environmental pollution caused by slurry overflow cannot be properly treated, related departments can also carry out fine payment, even shutdown influence can be caused, if shutdown is carried out, the construction influence is converted into economic cost, about at least 3000 yuan/day of miswork loss is caused, after the treatment is good, related departments can obtain approval, re-work and the like again, and calculated according to 7 days of miswork time, about 2.1 thousand yuan of miswork loss is caused. In conclusion, by adopting the mud management system of the embodiment, the mud and sand can be recycled, the outward transportation cost, the mud making cost and the mud tank cleaning time can be saved, and the influence caused by shutdown is avoided to a great extent.
