Product Description
RM-320 can be used in mine and tunnel construction. Pipe support is a kind of advanced support technology in tunnel construction. It uses the excavated and erected steel arch frame as a fulcrum. Within a certain angle range outside the top contour line of the excavated cave, several steel pipes are driven into the face stratum, and pressure grouting is carried out into the stratum through the plum blossom-shaped grouting holes to reinforce the weak and broken stratum. It is a measure to support and reinforce the stratum in advance.
In engineering construction, drilling technology is the factor that has the greatest impact on engineering costs and construction period. Choosing a reasonable drilling technology according to the specific engineering geological conditions is an effective means to ensure the economic benefits of the project. The drilling rig can realize a variety of drilling processes by matching different working devices, thereby realizing one machine for multiple uses, which also greatly expands the application field of the drilling rig.
You can rest assured to buy underground mining drill rigs from our factory, we will provide you with the best after-sales service and timely delivery.
