Several characteristics of self drilling anchor bolt

Several characteristics of self drilling anchor bolt

In general,anchor bolt and anchor cable is the most often used measures for protecting the stability of slope. But in the construction whatever use the large or small drilling machine, in order not to break the hole, you must use the casing ,this is virtually increase working hours. Especially drilling in the crushing zone or backfill area, which often caused slope slippery and formation disturbance and bring engineering disasters.

Even if the barely completed, often due to grouting confined to the casing, so that the anchor rope or anchor lack of force, resulting in failure. In addition, in the city with the available area is getting smaller, high-rise building and underground works (such as subway projects, MRT),but these deep excavation works, therefore, the stability of the excavation surface and the protection of the adjacent housing has become an important issue.

Self drilling anchor bolt; according to its several characteristics, we hope to achieve the effect of stabilizing slope, foundation excavation and improving geology, so as to make the project go smoothly.

Characteristics of self drilling anchor

(1)applicability is great. In any geological can be applied, including soft soil, backfill soil, garbage soil layer, the collapse of ten layers, soft rock, hard rock, gravel layer and other soft rock, hard rock are suitable for the river.

(2)timeliness is good. Because the drilling hole does not need to be put in the bushing and the hole, it can save most of the operation time, and can also perform the maximum function in the shortest time. When emergency rescue or urgent time limit is needed, the task can be completed in the shortest possible time.

(3)convenience is better. From the portable rig to small and medium-sized to large rig drill rig, may need to use flexible scheduling models, whether in narrow space or obstacle site, all construction, is not affected by the weather, all-weather construction.

(4)economic superiority. Due to the multiple function and applicability, it is quite convenient to save time, construction work or machine scheduling. The material itself or the alternative material is cheaper than any equivalent method. Therefore it can save a lot of money.

(5)high safety.because of its own tension, but also as grouting geological improvement, its performance than the traditional traditional method of pulling large, more stable stratigraphic function, so it can be said to spend the least cost, can get the maximum security.
