Pile casing device for brine stratum mucky soil cast-in-place pile construction
The invention discloses a pile casing device for brine stratum mucky soil cast-in-place pile construction, which comprises a pile casing head, a fixed transverse plate and an outer pile casing body, the upper surface of the pile casing head is fixedly connected with the fixed transverse plate, the lower surface of the pile casing head is fixedly connected with the outer pile casing body, and reinforcing ribs are fixedly arranged on the outer surface of the outer pile casing body. The number of the reinforcing ribs is four, a plurality of first through holes are fixedly formed in the outer surfaces of one sides of the reinforcing ribs, a partition plate is fixedly arranged on one sides of the first through holes, a plurality of second through holes are formed in the partition plate, and the second through holes correspond to the first through holes in position. The outer pile casing body, the first inner pile casing body and the second inner pile casing body are arranged, so that the phenomena that a pile body deflects, a pile hole shrinks, collapses and even cannot be formed easily in the drilling process when a sludge layer is thick or located in a middle layer are effectively avoided, a mud wall protection process is avoided, and pollution to underground soil and water is completely eradicated.
本发明公开了一种卤水地层淤泥质土灌注桩施工用护筒装置，包括护筒头、固定横板和外护筒体，所述护筒头上表面固定连接有固定横板，所述护筒头下表面固定连接有外护筒体，所述外护筒体外部表面固定设有加强筋，所述加强筋设置有四个，所述加强筋一侧外部表面固定设有若干个第一通孔，所述第一通孔一侧固定设有隔板，所述隔板上开设有若干个第二通孔，所述第二通孔与第一通孔位置对应设置，本发明设置了外护筒体、第一内护筒体和第二内护筒体，有效避免当淤泥层较厚或者位于中间层时，极易在钻孔过程中出现桩身偏斜，桩孔缩孔、塌孔甚至无法成孔的现象，避免了使用“泥浆护壁”工艺，杜绝了对地下土壤及水体的污染。
