Soft soil stratum cast-in-situ bored pile construction device
The invention relates to the technical field of cast-in-place pile construction, in particular to a soft soil stratum cast-in-place pile construction device which comprises a rotary drilling rig. The rack is mounted on a machine body on one side, far away from a drill bit, of the rotary drilling rig; the circumferential drilling mechanism is mounted on the rack and used for drilling reinforcing holes in the circumferential positions of the cast-in-place pile holes; the transverse trepanning mechanism is mounted on the circumferential drilling mechanism and is used for transversely trepanning the inner hole wall of the reinforcing hole after the reinforcing hole is drilled; the switching mechanism is mounted on the rack and is used for synchronously switching to drive the transverse trepanning mechanism to operate after the circumferential drilling mechanism stops; and the grouting mechanism is installed on the machine body of the rotary drilling rig and used for injecting grouting materials into the reinforcing holes. The method has the effect of solving the problem of differential settlement after soft soil stratum cast-in-situ bored pile construction.
本申请涉及一种软土地层钻孔灌注桩施工装置，涉及灌注桩施工技术的领域，其包括旋挖钻机；机架，安装在旋挖钻机远离钻头一侧的机体上；周向钻孔机构，安装在机架上，用于在灌注桩孔的周向位置钻设加固孔；横向开孔机构，安装在周向钻孔机构上，用于在加固孔钻设好后在加固孔的内孔壁上横向开孔；转换机构，安装在机架上，用于在周向钻孔机构停止后同步转换驱使横向开孔机构运行；注浆机构，安装在旋挖钻机的机体上，用于向加固孔内注入灌浆材料。本申请具有改善软土地层钻孔灌注桩施工后的不均匀沉降的问题的效果。
