Problems solved by technology

The inspection shaft sludge is a non-Newtonian fluid, which belongs to the category of Bingham (Bingham) body, and is in a semi-solid and semi-fluid flow-plastic state. It is difficult to clean and transport with existing technology and equipment, and it takes a long time to consolidate , the processing method is quite primitive

Embodiment Construction

[0016] Below in conjunction with accompanying drawing, the present invention will be further described.

[0017] A kind of inspection well silt consolidation removal method such as figure 1 As shown, a prefabricated rubber inspection well circle (3) is fixed below the drainage pipe (2) of the inspection well, and a prefabricated GPS plastic mud bucket (4) is placed on the inspection well circle, and the upper part of the mud bucket (4), has a The top ring is larger than the bucket body, and coincides with the inspection well ring (3), and the bottom of the mud collecting bucket has a filter hole and a filter membrane (7) containing polyacrylamide; The water carries the silt into the inspection well, and the silt sinks to form silt (5); in the dry season, the water level drops, and the water is discharged through the filter hole and filter membrane (7) at the bottom of the mud collection bucket to form bottom water (6) , the mud is separated from the water, and the silt (5) fo...

Abstract

The invention provides an inspection shaft sludge solidifying and clearing method, which belongs to city environment protection technologies. The inspection shaft sludge solidifying and clearing method comprises a method for arranging an inspection shaft ring and a sludge collecting bucket, a method for dehydrating and solidifying sludge to form a mud cake and a method for clearing the mud cake to a transfer station. The city inspection shaft sludge clearing and solidifying difficulties and a secondary pollution problem during conveying are solved; and the inspection shaft sludge solidifying and clearing method provided by the invention has the characteristics of simple structure, convenience in operation, low cost, remarkable work efficiency and suitability for clearing the inspection shaft sludge of various cities.

Description

technical field [0001] The invention relates to clearing and transporting sludge in urban manholes, which belongs to the urban environmental protection technology. Background technique [0002] The inspection well is used in the turning, branching, falling, etc. of the drainage pipe to facilitate inspection and dredging, that is, the sewer inspection well in the middle of the road. The urban inspection wells buried underground gradually accumulate thicker and thicker silt layers. Once the rainwater continues, it will block the drainage pipes, affect urban drainage, and bring great hidden dangers to urban flood control. It needs to be cleared in time. According to research, urban manhole silt is neither solid nor liquid, and belongs to the category of Bingham body. This kind of sludge is in a plastic state and flowing state, and has the characteristics of smelly, sticky, soft, and black. In the past, there was no advanced suction method, and it has always been an urgent pro...
