Description

Technical Field

[0002] With the rapid increase of urban population in my country, underground rail transit has become a major means to solve the problem of traffic deterioration. During the shield tunneling process, in order to achieve force balance on the face, water, bentonite, foam, high molecular polymer and other additives are added to the shield machine soil bin. Therefore, a large amount of water-rich slag will be produced during the shield process. Due to its high fluidity and poor stability, direct landfill of shield slag has serious safety hazards. In addition, if the shield slag is directly transported without treatment, it is easy to leak during transportation, affecting the appearance of the city and causing environmental pollution.

[0003] After searching, a Chinese patent discloses a mud dewatering device (authorization announcement number CN215176821U), including a dewatering box with a dewatering motor connected to the side end and a solidification box body with a feed port connected to the side end, the lower end of the solidification box body is fixedly connected to a base, and a feed pipe is fixedly connected between the dewatering box and the solidification box body, the lower end of the dewatering box is hinged to the base, a retractable adjustment mechanism is connected to the fixed frame, a fixing ring is fixedly connected to the side end of the dewatering box, and an adjustment rope is connected between the fixing ring and the retractable adjustment mechanism. Although the patented technology can flexibly adjust the inclination angle of the dewatering box according to actual dehydration needs by hingedly connecting the lower end of the dewatering box to the base, and by setting the retractable adjustment mechanism and connecting the adjustment rope between the dewatering box and the retractable adjustment mechanism, the dewatering box can be stored upright when idle to reduce the floor space;
