The invention discloses a foundation pit combined supporting construction device which comprises a drill rod and a base table used for installing the drill rod, the lower end of the drill rod is arranged in a tip mode to form a drill bit, the drill rod is arranged in a hollow mode to form a material storage cavity, and the material storage cavity communicates with the upper end of the drill rod. The outer wall of the drill rod is provided with a plurality of discharging holes communicated with the storage cavity, the discharging holes are distributed at the drill bit, the lower end of the drill rod is sleeved with an installation sleeve, the lower end of the installation sleeve is provided with a plurality of blocking pieces in the circumferential direction of the installation sleeve, the blocking pieces are rotationally connected to the installation sleeve, when all the blocking pieces abut against the drill bit, a reinforcing taper sleeve is formed, and all the discharging holes are blocked by the reinforcing taper sleeve. The drill rod is further provided with a driving assembly. The discharging hole is protected through the blocking piece, so that no sludge enters the discharging hole to block the concrete discharging hole in the pile hole process, the pile hole resistance is reduced, the follow-up concrete pouring smoothness can be ensured, and the pile hole filling pile construction is facilitated.
本申请公开了一种基坑组合支护施工装置，包括钻杆、用于安装钻杆的基台，钻杆下端呈尖端设置形成钻头，钻杆呈空心设置形成存料腔，存料腔连通钻杆上端，基台上设有用于给存料腔供给混凝土的供料机构，钻杆外壁开设有若干连通存料腔的出料孔，出料孔设有若干个且分布于钻头处，钻杆下端套设有安装套，安装套下端沿其周向设有若干阻挡片，阻挡片转动连接于安装套，所有阻挡片抵接于钻头时组成加强锥套，加强锥套阻挡所有出料孔，钻杆上还设有驱动组件。通过阻挡片对出料孔进行保护，使得在桩孔过程中不会有淤泥进入出料孔内堵塞混凝土出料孔，即减少了桩孔阻力，又可确保后续浇灌混凝土时的顺畅，方便了桩孔灌注桩施工。
