Couplings-Self Drilling Rock Anchors By Sinorock

Couplings

Couplings

Brief Introduction:

Sinorock® self drilling rock anchor system ,as a new construction technology, has been applied in anti-wall and slope projects. It can solve technological problems of lose stratum. Couplings is a part of Sinorock® self drilling rock anchor system,which consists of rock anchor, plate, nut, coupling, drill bit and centralizer.

Application:

1.The application in pressure device, such as static load test of pile, submerge and exacerbation of heavy box.
2.The supporting of tunnel and roadway, such as controlling the surrounding stratum’s deformation.
3.Reinforcement of bridge foundation, such as anchoring of suspension bridge, pier and large-span arched bridge.

Feature:

1. The machining method guarantees high precision of the thread. Coupling can screwed with self drilling rock anchor more tightly and providing better torque transmission.
2. High strength, stable performance
3. Chamfering makes the end clean, smooth and without any fur. Therefore, coupling can be screwed with self drilling rock anchor quickly, which provides convenience for the construction.
