Novel steel sleeve device for cast-in-situ bored pile construction
The invention relates to a novel steel sleeve device for cast-in-situ bored pile construction. The device comprises a plurality of steel sleeves (1) which are sequentially sleeved, at least one waterinjection pipe (3) and a plurality of drill bits (7), wherein the at least one water injection pipe (3) is vertically arranged on the outer side walls of the steel sleeves (1), and the plurality of drill bits (7) are arranged on the outer side wall of the bottommost steel sleeve (1) in the circumferential direction and extend downwards. Compared with the prior art, the device has the characteristics that the structure is simple, disturbance of construction to the surrounding environment is reduced, and the construction efficiency is high.
本发明涉及一种用于钻孔灌注桩施工的新型钢套管装置，所述装置包括多个依次套接的钢套管(1)、至少一个注水管(3)和多个钻头(7)，所述注水管(3)竖直设于钢套管(1)的外侧壁上，多个钻头(7)沿周向设于处在最下方的钢套管(1)的外侧壁上，并向下延伸设置。与现有技术相比，本发明具有结构简单、减少施工对周边环境扰动、施工效率高的特点。
