Compared with a conventional technology, the equipment provided by the invention realizes reduction and stabilization treatment of slurry, reduces subsequent slurry transportation costs, and effectivelysolves a current slurry treatment difficult problem in cities.

Description

technical field [0001] The invention relates to the technical field of shield tunneling / construction / river mud reduction and stabilization treatment, in particular to a water mobile mud treatment device and a treatment process. Background technique [0002] At present, the mud in the city mainly comes from construction engineering mud and river silt. With the continuous acceleration of urbanization and the rapid advancement of water environment management, the amount of mud produced is also increasing. Each cubic of natural soil can produce 3-4 cubic mud. Therefore, each project usually produces tens of thousands or even millions of cubic meters of mud that needs to be shipped out. Due to the high moisture content of the mud, most of the actual transported mud is water when the mud is directly transported outside, and the transportation efficiency is low, which greatly increases the urban traffic burden and causes energy waste. If it is not handled properly, it will not on...

AI Technical Summary

Problems solved by technology

[0003] At present, there are mainly the following mud processing methods, but all of them have relatively large disadvantages: 1. The tank truck (mud truck) is transported abroad. This method is to directly lift the mud generated on site into the mud truck through the mud pump. The mud is transported by mud truck to the free space on the outskirts of the city for natural drying, but the comprehensive cost of transportation, labor, management and other costs required by this method is relatively high, the comprehensive cost per cubic meter is high, and the consumption area is different. 2. On-site sedimentation and drying. This method needs to build a sedimentation tank on the construction site, discharge the generated mud into it, and carry out natural sedimentation and drying. Sometimes some flocculants are added for flocculation treatment before proceeding. Precipitation and drying, but this method needs to occupy a large area of ​​land, the treatment period is long, and it is easy to cause inconvenience to the construction site; 3. Centrifugal dehydration, a centrifuge can be used to dehydrate the construction mud, but due to the repeated stirring of the mud water during piling construction, the mud water The binding force is enhanced, especially for silty mud. It is difficult to quickly separate the mud and water by centrifugal force. At the same time, the energy consumption of centrifugal dehydration is large and the processing capacity is relatively low.
