Background

In order to meet the requirements of energy conservation, environmental protection and green construction, a drainage channel for discharging sewage is generally arranged at the periphery of the current construction site. In the work progress, especially the in-process of foundation ditch excavation, along with the increase of the volume of unearthing, the hack and the impurity that flow into water drainage tank also obviously increase, need wash the surperficial silt of car before driving out the building site like the fortune native car, building site personnel can regularly wash the raise dust hack etc. on ground with the water pipe in addition, these hack silt finally all can get into water drainage tank along with sewage, and constantly silts in water drainage tank, make water drainage tank passageway sectional area constantly reduce, cause the jam even. Therefore, the drainage groove needs to be periodically desilted in a construction site, and smooth drainage is ensured.

The whole process of desilting of prior art generally relies on the manual work to go on, and the manual work is opened the capping promptly, and reuse shovel digs out the interior silt of water drainage tank, and the manual work is covered back the capping again.

According to the dredging mode, a large amount of work such as cover lifting, dredging and covering is completed manually, the labor intensity is high, the labor cost is high, the working efficiency is low, and time and labor are wasted; moreover, the excavated sludge is often stacked on two sides of the drainage channel, and is required to be specially stored and cleaned, so that the labor cost and the labor intensity are further increased.
