Construction method for cast-in-place pile

Номер: CN104234043A
Автор: XIAO JIAN, BAI SHIXIN
Принадлежит:

The invention provides a construction method for a cast-in-place pile. The construction method comprises the following steps of burying a steel pile casing, and drilling a pile forming hole; placing a reinforcement cage fixedly provided with sounding pipes and a guide pipe. The construction method further comprises the following steps of cleaning the pile forming hole by using the sounding pipes, and meanwhile, pouring concrete into the pile forming hole by using the guide pipe to simultaneously finish hole cleaning and concrete pouring; after the concrete is initially set, checking pile forming quality in the sounding pipes. According to the construction method, hole cleaning and concrete pouring are simultaneously finished, so that construction time can be effectively reduced; a slurry-gas mixture and sediments at the bottom of the hole are ejected by the poured concrete, so that the hole can be completely cleaned without influence on the pile forming quality; a sediment and slurry discharge ...
