Embodiment 1
[0026] see figure 1 , an application method for rapid dehydration of urban river silt, comprising the following steps:
[0027] S1. Install high-pressure water pumps and mud pumps on the mud flushing working face, lay rubber nylon pipes for mud discharge, and draw clean water to supply water for high-pressure pumps. After the mud pumps pump mud, return water is available for use;
[0028] S2. Start the high-pressure pump and use the water gun to flush the ground with the mud to form a pool, and arrange a mud discharge pipeline. The mud discharge pipeline is mainly made of underwater submerged pipes, with a small amount of floating pipes and land pipes;
[0029] S3. The underwater submersible pipe is connected to the floating pipe on the water, and connected to the land pipe to extend to the mud discharge area;
[0030] S4. Put down the mud pump to suck the mud, transport it to the mud discharge area through the mud discharge pipeline, and then clear and transport the mud thro...

Abstract
The invention discloses an application method for rapid dehydration of urban river silt, and relates to the technical field of river construction, wherein the application method comprises the following steps: S1, a high-pressure water pump and a slurry pump are arranged on a sludge flushing working surface, a sludge discharging rubber nylon pipe is laid, clear water is pumped to supply water for ahigh-pressure pump, and water is returned to be used after the slurry pump conveys sludge; S2, the high-pressure pump is started to flush the ground where slurry is located through a water gun, a pool is formed, a sludge discharging pipeline is arranged, and the sludge discharging pipeline is mainly composed of underwater submerged pipes and matched with a small number of floating pipes and landpipelines; and S3, the underwater submerged pipes are communicated with an overwater floating pipe and communicated with the land pipeline to extend to a sludge discharge area. According to the application method for rapid dehydration of the urban river silt, an FSA and HEC material is used for improving the water permeability of the slurry, so that the dehydration efficiency is improved, the construction period is short, meanwhile, the filtered water is clear, the suspended matter index reaches the first-grade standard of national sewage comprehensive discharge water, the occupied area is small, and the urban river silt directly enters dehydration consolidation equipment for dehydration treatment.
Description
technical field [0001] The invention relates to the technical field of river channel construction, in particular to an application method for rapid dehydration of urban river channel silt. Background technique [0002] With the acceleration of the country's urbanization process, the backlog of river silt is becoming more and more serious. According to the data of the Guangzhou Municipal Water Affairs Bureau, the silt storage capacity of the rivers in Guangzhou is about 10 million cubic meters. Among them, there are more than 120 rivers that are currently in urgent need of treatment, with a length of about 388.52 kilometers. More than 10,000 cubic meters, the river muddy water environment has the following characteristics: the river network structure is criss-crossed, the silt is serious, and the silt pollution is serious, the silt has a wide range of sources and complex components; the water quality is seriously polluted and the factors are complex. [0003] Sludge dewateri...
