摘要

The present invention discloses a pile bottom grouting cavity, a method of using the same, a cast-in-place pile and a construction method thereof. having a grouting capsule; a grouting pipe communicating with the inner chamber of the grouting capsule and performing grouting in the grouting capsule; and a fixing plate on which the grouting capsule is installed and communicated with the co-bottom of the accommodating hole and provided with a through-hole for allowing the slurry and/or the deposits in the accommodating hole to pass therethrough. In the prior art, cast-in-place piles having a grouting capsule in the board pile construction process, causing collapse of hollow walls and exceeding the standard value of deposits, and to solve the problem that greatly affects the construction quality.
