1.
Specially developed for self drilling anchor bars, which can give full play to the advantages of its technology.2. According to application scenarios, the power unit parameters are optimized, which can carry out high-frequency impact and high-speed rotation, and the slag discharge is smoother and the drilling speed is faster.
3. The standard anti-driving function can effectively solve the stuck problem during drilling.
4. Fully hydraulic control, convenient and flexible operation. Hydraulic valve group are imported from Italy, and they are stable, reliable and low failure rate.
5. High price/performance ratio, the price is only 1/3-1/2 of similar foreign drilling rigs.
6. The maximum lifting height is 3.3 meters. Construction work surface is large and multiple rows of holes can be drilled at one time.
7. Particularly suitable for complex geological conditions (broken rock layer, loose rock and soil layer, etc.), such as clay, silty clay, especially soil with rock, miscellaneous fill, pebbles, gravels etc., which are difficult to form holes.
8. Drilling and grouting are carried out simultaneously, the grout can effectively fill the rock fissures, and the diameter of the grout body is large with good anchoring effect.
