Recyclable double-layer steel sleeve for static load test of cast-in-situ bored pile and method
The invention relates to a recyclable double-layer steel sleeve for a static load test of a cast-in-situ bored pile and a method. Rubber waterstops are arranged at the top ends and the bottom ends of double sleeves, and sealing materials are arranged in the upper sections and the lower sections of the double sleeves to serve as temporary fillers. Four special-shaped lifting lugs are welded to the inner sleeve bodies and the outer sleeve bodies at the top ends of the double sleeves. An auxiliary steel lifting lug is mounted at the downward 2/3 positions of the tops of the double sleeves. The method comprises the following steps that (1), the recyclable double-sleeve structure is designed; (2), the recyclable double sleeves are assembled and combined; (3), the recyclable double sleeves are hoisted and mounted; and (4) the outer sleeve is disassembled and recycled after the static load test is completed. The problem that slurry and concrete enter the pipe wall of a traditional double-sleeve pipe due to the fact that the top of the traditional double-sleeve pipe is open and the problem that the double-sleeve pipe is fixed to an orifice of a cast-in-situ bored pile after being mounted are solved, and the outer sleeve pipe can be recycled after the test is completed.
本发明涉及一种可循环利用的钻孔灌注桩静荷载试验双层钢套管及方法，该双层钢套管中的双套管顶端及底端处设置橡胶止水带，双套管上下部分段内设置密封材料作为临时填充；双套管顶端内外套管焊接有四个异形吊耳；双套管顶向下2/3位置处安装一只辅助钢吊耳；该方法包括：1)可循环利用双套管结构设计，2)可循环利用双套管的拼装、组合形式，3)可循环利用双套管的起吊、安装方法，4)外套管静荷载试验完成后的拆除回收。本发明解决了传统双套管顶部开口使泥浆、混凝土进入双套管管壁的问题以及双套管安装完成后在钻孔灌注桩孔口固定的问题，且在实验完成后外套管可回收并重复利用。
