With the acceleration of urbanization, the construction of underground transportation, municipal engineering, water conservancy engineering and other infrastructure is increasing, and tunnel engineering has been widely used as a new type of transportation and municipal construction. In the process of tunnel construction, the shield method has become the mainstream construction method because of its advantages of high efficiency, safety and environmental protection. However, the shield method will produce a large amount of mud during the construction process, and how to effectively deal with these muds and reduce the impact on the environment has become an urgent problem to be solved in tunnel construction. To this end, shield mud treatment equipment came into being, which provides a strong guarantee for the green development of tunnel engineering.
Shield mud treatment equipment is a kind of equipment specially used to treat the mud generated in the process of shield construction, and its main role is to carry out solid-liquid separation, dehydration, purification and other treatment of mud, so that the mud can meet the discharge standard and reduce environmental pollution.
The main advantages of shield slurry treatment equipment are as follows:
1.High efficiency: The shield mud treatment equipment adopts advanced solid-liquid separation, dehydration and purification technology, with high treatment efficiency, which can meet the mud treatment needs of large-scale tunnel projects.
2.Environmental protection: The shield mud treatment equipment can remove the harmful substances in the mud, so that the mud can meet the environmental protection discharge standards and reduce the pollution to the environment.
3.Energy-saving: The shield mud treatment equipment adopts energy-saving design, low operating cost, and can save a lot of energy for tunnel engineering.
4.High degree of automation: The shield mud treatment equipment adopts advanced automatic control technology, which is easy to operate and easy to maintain.
5.Space-saving: The shield mud treatment equipment has a compact structure and a small footprint, which is convenient for construction site layout.
Plate and frame filter press equipment to process shield slurry.
1. First, the shield muck is screened with a vibrating screen, then deeply cleaned by a wheeled sand washer, and fine sand can be obtained through a dewatering screen, which is transported to the fine sand accumulation through a belt conveyor.
2. The shield mud washed out of the sand flows into the mud collection tank, and the flocculant in the chemical system is stirred and the mud in the mud collection tank is pumped to the deep cone mud separation tank for reaction, and the sludge and the clean water are separated and precipitated after mixing, and the clean water enters the clear water pool.
3. The flocculated slurry enters the plate and frame filter press through the special filter press pump for solid-liquid separation. The dry mud cake is transported to the designated area, and the clean water is discharged and recycled through the filter press. The use of environmental protection technology can effectively reduce the pollution of shield muck to the environment.
Summary: In short, shield mud treatment equipment has important application value in modern tunnel construction. It can not only effectively deal with the mud generated during the shield construction process and reduce the impact on the environment, but also improve the construction efficiency and reduce the project cost. With the continuous development of tunnel engineering construction, shield mud treatment equipment will be more widely used, providing a strong guarantee for the green development of tunnel engineering. At the same time, the research and technological innovation of shield mud treatment equipment will continue to advance to meet the needs of future tunnel engineering construction.
