定值锚头回收锚索技术

Recoverable Anchor Cable with Fixed Value Anchor Head

定值锚头回收锚索是一种新颖的临时基坑锚索支护及锚索回收方式,从锚索底端的特制锚头装置入手,将该特制锚头握裹力设计成一个定值,形成定值锚头,使其既能满足临时基坑支护的锚固力要求,又能满足临时基坑支护工程任务完成后锚索的顺利回收。通过大量工程应用表明:定值锚头可回收锚索的技术性能可靠、结构简单、施工方便、成本低廉,回收率可达100%。

Using fixed value anchor head to recover anchor cable is a novel method of anchor support and cable recovery in temporary foundation pit. It starts with the special anchor head device at the bottom of the anchor cable, designs the gripping force of the special anchor head into a fixed value, and forms the fixed value anchor head. It can not only meet the demand of anchoring force of temporary foundation pit support, but also satisfy the successful recovery of anchor cable after the completion of temporary foundation pit support project. Through a large number of engineering applications, it is shown that the technical performance of the recoverable anchor cable is reliable, the structure is simple, the construction is convenient, the cost is low, and the recovery rate is up to 100%.
