Description
Technical field
The utility model is a kind of anchor cable, and the recyclable anchor cable of a kind of specifically self-drilling belongs to anchor field of fixation devices in the geotechnical engineering.
Background technology
Present stage engineering construction scale progressively enlarges, and the excavation of foundation pit degree of depth strengthens gradually, and also more and more to the demand of prestress anchorage cable, single anchor cable length is also more and more longer.Anchor cable is used very extensive in China's underground engineering construction as a kind of support anchoring structure.It has the reliability height, and bearing capacity is big, and construction cost is low, and speed of application is fast, technology maturation, and the operation element face is little, the many-sided advantage of the little grade of structure exposed parts.But there is following shortcoming simultaneously:
1. anchor cable need take a large amount of underground spaces (more than 40 meter of up) in the supporting and protection structure outside, and outside regular meeting occupied the construction land red line, this was unallowed legally, brings obstacle and difficulty also for simultaneously neighbouring entry purpose underground engineering construction.
2. the foundation ditch stream line belongs to temporary works, has just lost use value after pit backfill, and wherein steel strand are embedded in the underground meaning that loses, if do not remove the waste that recycling just causes resource.
Therefore inventing a kind of dismountable prestress anchorage cable just seems that realistic meaning is arranged very much.
Present recyclable anchor cable needs pore-forming in advance mostly, and steel strand and detachable anchor device such as JCE type, U type etc. are put in the back.To require hole wall to stablize smooth for pore-forming in advance, and it is straight to hole, and only in this way could guarantee that follow-up steel strand etc. lay that everything goes well with your work carries out.Hole wall is stablized smooth common needs with sleeve pipe or mud off, and the straight requirement of holing is difficult to guarantee fully at sand soft rock layer.These measurements for construction assurance and actual conditions have increased the cost of recyclable anchor cable, are unfavorable for large-scale promotion.Therefore invent a kind of recyclable anchor cable of self-drilling that just can finish pore-forming, lay steel strand, lay operation such as anchor device that once creeps into and just seem that realistic meaning is arranged very much.
Summary of the invention
Goal of the invention
The purpose of this utility model is to develop a kind of safe and reliable, detachable, tension bearing capacity height of finishing using, construction cost is low, environmental pollution is little, be convenient to the anchor cable that large-scale promotion is used.
