Cast-in-place pile trepanning and anti-sloughing hole processing device in easy-to-collapse stratum
The invention discloses a cast-in-place pile trepanning and anti-collapse hole processing device in an easy-collapse stratum, and relates to the field of cast-in-place pile trepanning. The cast-in-place pile trepanning and anti-collapse hole processing device in the easy-collapse stratum comprises a main rack, a limiting unit is arranged between an outer pile casing and an inner pile casing, a sliding unit is arranged below a protection plate, and a communicating unit is arranged between an upper sliding frame and a lower sliding frame. According to the cast-in-place pile trepanning and hole collapse prevention treatment device in the easy-collapsing stratum, when hole trepanning is carried out and collapse occurs in a hole, a lower fixing frame drives a lower sliding frame to slide, soil is compacted, and continuous collapse is avoided, and when collapse is serious, a connecting pipe communicated with a communicating pipe is communicated with a main pipe, slurry is injected into the hole, and the hole collapse is prevented. And collapse is relieved through the injected slurry until the hole is filled with the slurry, the hole wall is stabilized, and serious collapse in the hole is prevented in cooperation with a protection plate.
本发明公开一种易塌地层中灌注桩开孔及防塌孔处理装置，涉及灌注桩开孔领域。该易塌地层中灌注桩开孔及防塌孔处理装置，包括主机架，所述外护筒与内护筒之间设置有限位单元，防护板下方设置有滑动单元，上滑动框与下滑动框之间设置有连通单元。该易塌地层中灌注桩开孔及防塌孔处理装置，当进行开孔时，出现孔内塌陷情况发生，下固定架带动下滑动框进行滑动，将土压实，避免塌陷持续进行，当出现塌陷严重时，通过与连通管连通的连接管与主管连通，将泥浆向孔内注入，通过注入的泥浆进行塌陷的缓解，直至将孔内注满泥浆，对孔壁进行稳固，配合防护板防止孔内塌陷严重。
