Construction method for cleaning original underground building foundation through all-sleeve pile extractor and all-sleeve pile extractor
The invention relates to a construction method for cleaning an underground original building foundation by using an all-casing pile extractor, which comprises the following steps of: detecting and positioning the underground original building foundation to be removed, and burying a pile casing on the ground right above the original building foundation; the all-casing pile extractor is moved to the position close to the pile casing, and the lower end of an all-casing of the all-casing pile extractor corresponds to the pile casing; the all-casing pile extractor is connected with a hydraulic station, and the hydraulic station is used for providing power to drive the all-casing to drill into a soil body below until the set target depth is reached; cutting and removing the original building foundation through a tool bit arranged at the end part of the full sleeve; pulling out the full sleeve, and crushing the taken original building foundation; a hole channel left after the whole casing pipe is pulled out is subjected to filling treatment; and the construction steps are repeated until the original underground building is cleaned. According to the construction method for cleaning the original underground building foundation through the all-casing pile extractor, the stability of a construction soil body can be effectively maintained through the pile casing and the all-casing, the original building foundation is segmented through the tool bit and is taken out, the working efficiency is improved, generated hole channels are filled, soil body collapse can be effectively prevented, and the construction quality is guaranteed.
本发明涉及一种利用全套管拔桩机清理地下原有建筑基础的施工方法,包括如下步骤:对地下待拆除的原有建筑基础进行探测以及定位,并在原有建筑基础正上方的地面处埋设护筒;将全套管拔桩机移动至护筒附近,并将全套管拔桩机的全套管下端与护筒对应;将全套管拔桩机与液压站连接,利用液压站提供动力驱使全套管向下方土体内钻进,直至到达设定的目标深度;通过全套管端部设置的刀头对原有建筑基础切削并兜出;将全套管拔出,对取出的原有建筑基础粉碎处理;对全套管拔出留下的孔道做填充处理;重复上述施工步骤,直到将地下的原有建筑清理完毕。本发明一种利用全套管拔桩机清理地下原有建筑基础的施工方法中,通过护筒和全套管,可以有效维护施工土体的稳定,且用刀头切分原有建筑基础并兜出,提高了工作效率,对产生的孔道填充,能够有效防止土体塌陷,保证施工质量。
