Self drilling anchor support

Self drilling anchor support can take full advantage of soil body’s self-bearing capacity. Compared to shotcrete support, it has characters of safety, high efficiency and convenience. It can be
operated at small spaces, so under allowable condition, adopting self drilling anchor can enhance efficiency largely.

Sinorock self drilling anchor can be used as the micropiles,here some advantages of self drilling anchor as micropile:
1. High work efficiency
Self drilling anchor system is usually used as a micropile. The hollow anchor bar can be regarded as a disposable drill rod, grouting pipe and reinforcement bar, so it can realize drilling, installation and grouting in one step. Without casing and grouting pipe, self drilling anchor can drill and grout directly. The operation steps will be less, the work efficiency will be higher, and the workload will be reduced.

2. Good anchoring effect
The friction between the micropile and the soil is high. The slurry can cover all the cracks around the drill hole, which can reach a good corrosion protection effect.

3. Strong adaptability
The full length of threaded hollow anchor bar can be cut arbitrarily. Self drilling anchor is suitable for small lightweight drilling equipment. It also can be used in remote areas or limited space where large equipment can not reach, such as steep slope, wet land, dock foundation, basement, overpass, etc.

4. Environmental protection
(1) Rotary percussion drilling causes low noise and small vibration.
(2) Both of self drilling anchor bolt and cement are environmentally friendly materials, without pollution to the soil.
(3) The drilling process has a lower pressure erosion effect on the surrounding environment, without damage to the nearby buildings.
