(Presseportal openBroadcast) - In actual engineering, foundation excavation design should transform from traditional intensity control to deformation control, in order to avoid damage for surroundings. Subway stations and other underground engineering are usually constructed in dense building
group and construction plant is narrow, which will probably bring security problems.
Foundation excavation accidents are often manifested as followings: displacement of supporting structure is oversize, surrounding
roads and buildings crack or collapse, underground pipe network is destroyed and other damages.
Based on different geological and hydrological conditions, deep foundation excavation support should adjust measures to local circumstances.
Self drilling hollow anchor bolt combines drilling, grouting and anchoring together in narrow places with little noise and little influence on surroundings. With different materials, self drilling hollow anchor bolt is convenient, economic, reliable, secure and
efficient supporting method.As an efficient anchoring method, self drilling anchor bar is mainly used for slope stabilization, foundation with micropiles and tunneling, itís also widely used in the railway system, metro project, etc. It can be installed in sites with weak rocks, loose soil, weathered layer, sand with stone layer and so difficult to create a hole in complex formation. The unconsolidated ground condition favor the self drilling anchor bar technique for fast and simple method of installed compared to the traditional method.
In modern tunnelling, especially in subsidence-sensitive or urban areas, the usage of self-drilling pipe umbrella support is a widely and successfully adapted spacious pre-support system.
