T52 Self Drilling Hollow Bar
  • T52 hollow anchor bolt as a new construction technology, has been applied in retaining wall and slope projects. It can solve technological problems on loose soil.

Function:

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 suspension bridge, bridge pier and large-span arched bridge.

Features:

1. High efficiency of construction.
2. Good adaptability.
3. High anchoring force.
