High-Pressure Jet Grouting Pile Drill, Jet Grouting Trolley, Jet Grouting Trolley is the same rig?
1. High-pressure jet grouting drilling rig, or high-pressure rotary jet pile drilling rig, refers to the drilling rig can be engaged in high-pressure rotary jet pile construction. As for whether the drilling rig can be engaged in single-pipe high-pressure jet grouting pile construction, double-pipe or three-pipe high-pressure jet grouting pile construction, or swing spray construction, this is related to the performance of the drilling rig design.
2. Anti-floating anchor pile machine refers to a drilling rig that can engage in anti-floating anchor construction. Relative to the long spiral aperture above 400mm, the aperture of an anti-floating anchor is mostly within 400mm. Drilling, grouting, steel bar, bend, this is the construction technology of anti-floating anchor. Because the high-pressure jet grouting pile and anti-floating anchor are vertical to the ground, as long as the torque of the drilling rig is enough, it is a drilling rig in the replacement of variable diameter, guide, drill pipe, and other drilling tools, it can achieve a machine multi-purpose.
3. High spray trolley, high, refers to the elevated, spray, refers to the high-pressure jet grouting pile. Drilling and spraying integrated trolley is a new concept proposed in recent years. The so-called integrated drilling and spraying, initially, refers to the high-pressure jet grouting pile construction, drilling, and high-pressure jet, the two into one. Compared with the high-pressure rotary jet grouting pile machine with small torque, after encountering complex strata, only the geological drilling rig can be used to guide the hole, and then the high-pressure rotary jet grouting pile drilling rig can be used for high-pressure injection. The high torque double motor power head, relies on large torque drilling, jetting, "drilling" and "jetting" two processes two in one, so-called drilling and jetting integration.
With the passage of time, the scope of the integration of drilling and spraying is gradually extensive. Its "spraying" is not only limited to high-pressure spraying but also often appears in the "mud injection" or "M30 mortar injection" of anti-floating anchors. After all, with a lot of pebble layers, and strongly weathered strata, some drilling rig is difficult to drill and grouting two processes two in one, so the drilling and spraying integration is particularly important. Now the project unit price is too transparent, saves a process, reduces labor costs, there is a market, and there are profits.
In essence, the integration of drilling and blasting is still a relative concept. Taking the granite layer as an example, it is difficult to have a drilling rig on the market to achieve the integration of drilling and blasting.
