Reinforcement work of tunnel project

Tunnel project is often launched in various kinds of complicated region,in order to make sure the stability of excavation surface and prevent the collapse of tunnels,rock bolt forepoling will be considered in advance,fore-small tube,grouting and other strengthening technology should be involved,especially in the condition of broken rock,loose soils,weak soils and sandy gravel as well as fine particles.

 

Pre-reinforcement determines weather the construction of tunnel and foundation perform well or not.

Shallow depth in the tunnel engineering, weak rock, joints fractured, poor self-stability ,it's difficult to form a balanced arch effect which occurs when a bassoon studio facilities are ready for challenge hole.

 

Self-drilling anchor adopts steel tube and angle steel as its raw material and will be installed into the soil directly.There are a great many applications that self-drilling anchor and soil nail can be covered in,which contain clay and soft soil,hard plastic or solid clay,dust,sandy gravel of consolidation or weak cementation,weathered rock and embankment and so on.

 

Reinforcement work and slope stabilization are the foundamental parts in the rock construction and has been extensively implemented in the mining,tunneling,hydroelectric project,water energy,retaining wall and other large rocking engineerings.
