Construction method for anti-sliding cast-in-place pile

The invention discloses a construction method for an anti-sliding cast-in-place pile. According to the technical scheme, the construction method is characterized in that means of timely pumping water and quickening warehousing during pouring, and technical means of quickening initial setting of concrete are adopted at a place where a slope body with a slope surface close to the river has relatively great water seepage, possibly collapses and sinks, and causes great difficulty to pouring construction. The construction method has the advantages that a submersible pump is adopted for draining off water when a water yield in an excavation process is relatively small, in-hole two-fluid water-stop slip casting is firstly carried out before every-time excavation construction when the water yield is relatively great, wherein every-time excavation depth is 1m, two-fluid slip casting holes are arranged along the periphery of a pile hole according to hole depth of 1.5m and spacing of 0.5m, so that the wall body collapse can be effectively controlled; and in a concrete pouring process, a C30 slump constant is as small as possible, and a necessary accelerating agent is added, so that pile body stabilization can be quickened.
