SMW Drilling Rig

SMW continuous wall is the abbreviation of soil mixing wall. It came out in Japan in 1976 and now accounts for about 50% of the diaphragm wall in Japan. This method has been widely used in Southeast Asian countries, the United States and France. In recent years, it has been widely used in Shanghai, Hangzhou, Nanjing and other places in China.The SMW construction method is to use special multi axial mixing to drill and cut the soil, at the same time, the cement slurry is injected into the soil at the end of the bit. After full mixing and mixing, the overlapping construction is adopted between the construction units. Before the cement soil mixture is hardened, H-shaped steel or other profiles are inserted into the mixing pile to form a continuous and complete joint free one with certain strength and stiffness Underground continuous wall, which can be used as retaining and sealing structure of underground excavation foundation pit. Drill type mixer is the most common shaft.
characteristic

1. Low project cost: compared with the traditional diaphragm wall, the SMW construction method with multi axis drilling rig has a strong competitive advantage in price.
2. Short construction period: compared with other construction methods, the time of SMW construction method is greatly shortened. Under general geological conditions, each shift can form a wall of 70-80m cubic meters.
3. Good water stop: there is no joint in the whole length of the wall, and the permeability coefficient K can reach 10-7cm / s.
4. Do not disturb the adjacent soil: it will not cause adjacent ground subsidence, house incline, road crack and underground facilities displacement.
5. Wide range of application: it can be used in clay, silt, sand, gravel soil and other rock strata.
6. The amount of waste soil transported out is far less than that of other construction methods.

Product features

Hydraulic double winch with large drawing force
Hydraulic winch with large drawing force is adopted. The main winch and the lifting winch are separated and used separately and can be interchanged.
Inverted installation of Outrigger
The outrigger is installed upside down to protect the oil cylinder and prolong its service life.
Comfort and safety
The cab is clean and quiet with wide vision, which provides convenient, comfortable and safe driving space for operators.
Walking structure with high stability
Long and short ships have large grounding area and small grounding pressure, which can effectively avoid the machine sinking and greatly enhance the stability of the whole machine.
