In TBM construction, small pilot pits are used to follow up with full-section blasting. In the same tunnel, the guide is in the front, and the full-section reaming light blasting surrounding rock has a good arch shape, and then supports and lining. The quality is high and the progress is fast. It can ensure that the lining is beautiful inside and outside, and the installation of waterproof boards can effectively play a waterproof role to ensure that the lining does not seep and leak.

Bored Pile refers to the pile hole formed in the foundation soil by means of mechanical drilling, steel pipe extrusion or manual excavation at the project site, and a steel cage and poured concrete are placed in it. Different, cast-in-place piles can be divided into immersed pipe cast-in-place piles, bored cast-in-place piles and excavated bored cast-in-place piles.

For both construction projects, Drilling Slurry plays an important role. Mud not only helps balance formation pressure, but also protects the wellbore and helps carry out solid waste during construction. Desanding Plant for Slurry Separation/Treatment is used more and more widely in modern TBM and Bored Pile construction projects because mud chemicals are not only expensive but also can contaminate the formation.

Working Process of TBM and Bored Pile Desanding Plant for Slurry Separation

1. With the help of pit pump, the Slurry from mud pit enter into the under screen of the shale shaker.
2. The slurry across the screen, enter into the mud tank.
3. With the help the help of the slurry pump on the slurry separation system, slurry enter into the cyclone.
4. After the centrifugal separation of the cyclone, the liquid go to the upper outlet, and the solids go to the under screen of the shale shaker. After the separation of the screen, solids go out of the slurry separation system.
5. If the customer chooses the three-stage purification treatment, then the Slurry will first enter the desander cyclone, and after the centrifugal separation of the desander cyclone, a feed pump will be supplied to the desander cyclone for the second centrifugal separation. If the customer is equipped with a centrifuge or filter press, there is another feed pump to supply the liquid phase from the desilting cyclone to the centrifuge or filter press.

Advantage of TBM and Bored Pile Desanding Plant for Slurry Separation

1. According to the situation of the TBM and Bored Pile project, such as different formation conditions and different construction techniques, we can choose two-stage treatment, three-stage treatment equipment, or other combination schemes (such as the combination of skid-mounted filter press units) .
2. For Desanding Plant for Slurry Separation with a processing capacity of more than 360 m3/h, we will use Multi-Unit Desanding Plants, a combination of multiple equipment to complete Slurry Separation.
3. Due to the construction process characteristics of the TBM and Bored Pile project, we can choose the on-site configuration plan of the equipment. In view of the large working space at the work site, we choose multiple devices to be placed side by side and used in parallel, which not only improves the safety of operation, but also reduces the cost by the convenience of on-site maintenance of the equipment. If the working space on site is relatively cramped, we can choose a design scheme in which multiple devices are stacked together. ZH has customized solutions for different customers and for different constructions.
