Construction method for isolation pile close to building
The invention relates to a construction method for an isolation pile close to a building, which is arranged between a foundation pit and a building structure, and is characterized by comprising the following steps: constructing an enclosure isolation area between the foundation pit and the building structure, and arranging the enclosure isolation area along the extension direction of the foundation pit; a plurality of pieces of H-shaped steel are arranged at intervals in a guide hole in the side, close to the foundation pit, in the enclosure isolation area; a plurality of first row of MJS swing spraying holes are formed in the side, close to the building structure, of the enclosure isolation area at intervals; grouting is conducted on the first row of MJS swing spraying holes, and rotary spraying is conducted by 180 degrees to form a first row of MJS construction method piles; and a second row of MJS swing spraying holes are formed in the side, close to the foundation pit, of the enclosure isolation area and opposite to the first row of MJS swing spraying holes, grouting is conducted on the second row of MJS swing spraying holes, rotary spraying is conducted by 180 degrees, so that a second row of MJS construction method piles are formed, and the arc-shaped sections of the second row of MJS construction method piles are arranged away from the foundation pit.
本发明涉及一种用于临近建筑物的隔离桩的施工方法，设置于基坑和建筑结构之间，其特征是，包括如下步骤：于所述基坑和所述建筑结构之间构设围护隔离区域，所述围护隔离区域沿所述基坑的延伸方向设置；于所述围护隔离区域内且靠近基坑的一侧引孔间隔打设若干个H型钢；于所述围护隔离区域且靠近所述建筑结构的一侧间隔打设若干个第一排MJS摆喷孔；于所述第一排MJS摆喷孔注浆并旋喷180度以形成第一排MJS工法桩；于所述围护隔离区域靠近所述基坑的一侧且与所述第一排MJS摆喷孔相对的位置打设第二排MJS摆喷孔于所述第二排MJS摆喷孔注浆并旋喷180度以形成第二排MJS工法桩，所述第二排MJS工法桩的弧形段远离所述基坑设置。
