Embodiment Construction

[0019] The embodiment is a method for sucking and transporting sludge in an urban manhole.

[0020] Urban manhole silt, which is neither solid nor liquid, belongs to the Bingham body category. 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 problem to be solved in urban development.

[0021] Such as figure 1 As shown, the carrier vehicle (1) is provided with a mud storage box (2), a crane (3), a control box (8), and a suction device (6) and an inspection well cover hook are hung on the crane (3) .

[0022] Suction device (6) includes: working cylinder (26), connecting rod (25), piston (23), mud inlet valve (22), mud outlet valve (20), mud suction port (21), mud passage (19) , liquid channel (24). There is a mud pipe (5) to be connected between the mud passage (19) of the suction device (6) and the mud box (11). Th...

Abstract

The invention discloses an inspection well sludge pipeline sucking and transporting method, and belongs to pipeline transportation technology of non-Newtonian fluid. The method comprises that a sludge sucking and transporting car is driven to the side of an inspection well, an inspection well cover is opened, a pipeline sucking device is inserted into the inspection well sludge, the sucking device is started, the inspection well sludge is conveyed to a sludge box, the inspection well cover is closed, the sludge is transported to a transfer station and is poured in an underground stainless steel container, and the sludge is dried in the shade and molded through solidification, so that pollution of the sludge to the ambient environment is avoided effectively. The method solves the problems of cleaning of the pipeline, transporting of the inspection well sludge and secondary pollution in the process of transportation. The method has the advantages of being simple in structure, convenient to operate and low in cost. The method is suitable for cleaning and transporting of the inspection well sludge in a city, and meanwhile can be widely used in petroleum, chemical industry, mining, water conservancy, environment protection and constructional engineering.

Description

technical field [0001] The invention relates to the removal and transportation of sludge in urban manholes, and belongs to the pipeline transportation technology of non-Newtonian fluids. 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. [0003] According to statistics, there are hundreds of thousands of inspection wells in a medium-sized city, and the silt produced every year is about several million tons. In addition, a class of industrial by-products and wastes such as primary coal slime and papermaking sludge are involved in the rem...
