Construction method for pulling out building pile foundation
The invention provides a construction method for pulling out a building pile foundation, which comprises the following steps of: 1, excavating a foundation pit, determining the position, the diameter and the length of the pile foundation, and excavating the foundation pit around the pile foundation; 2, steel sheet pile construction: selecting a steel sheet pile with a preset length for enclosure according to the length of a pile foundation, and driving the steel sheet pile in a preset distance range around the pile foundation; 3, grouting operation is conducted, specifically, grouting guide pipes are arranged around the pile foundation and between the steel sheet piles and the pile foundation, and then grouting is conducted through the grouting guide pipes; and fourthly, the pile foundation is pulled out, grouting is carried out in the pile foundation hoisting and pulling-out process, and the pile hole is backfilled immediately after the pile foundation is pulled out. The construction method for pulling out the building pile foundation can be suitable for pulling out waste piles of buildings such as municipal administration, rail transit and residence; the construction efficiency is effectively improved, and the construction safety is ensured. And the construction cost can be effectively saved.
本发明提供了一种用于建筑桩基拔出的施工方法，包括如下步骤：一、基坑开挖，确认桩基位置、桩径及桩长，并围绕桩基开挖基坑；二、钢板桩施工、根据桩基长度选用预设长度的钢板桩进行围护，延桩基四周预设距离范围内打入钢板桩；三、注浆操作，在桩基周围布设注浆导管，并布设于钢板桩与桩基之间，然后通过注浆导管进行注浆；四、桩基拔出，桩基吊装拔出的过程，同时进行注浆，桩基拔出后立即回填桩孔。该发明的一种用于建筑桩基拔出的施工方法，可适用于市政、轨道交通、住宅等建筑的废桩拔出；有效地挺高施工效率，保证施工安全。可有效地节约施工成本。
