Construction method of foundation pit fender posts arranged adjacent to edge of tunnel
The construction method is arranged between a foundation pit and a tunnel and comprises the following steps that a plurality of first-row MJS swing spraying holes are formed in one side of the tunnel at intervals, and the depth of the first-row MJS swing spraying holes is consistent with the driving depth of I-shaped steel; grouting is conducted on the first row of MJS swing spraying holes, a semicircular first row of MJS isolation piles are formed, the arc-shaped sections of the first row of MJS isolation piles face the foundation pit, and every two adjacent first row of MJS isolation piles are partially overlapped; a plurality of pieces of I-shaped steel are arranged on the soil body outside the foundation pit and located between the foundation pit and the tunnel at intervals; a second row of MJS swing spraying holes are formed between every two adjacent I-shaped steel, and the depth of the second row of MJS swing spraying holes is consistent with that of the I-shaped steel; and grouting is conducted on the second row of MJS swing spraying holes to form a semicircular second row of MJS construction method piles, and the first row of MJS isolation piles and the second row of MJS construction method piles are partially overlapped, wherein the first row of MJS isolation piles and the second row of MJS construction method piles are oppositely arranged.
本发明涉及一种紧邻隧道边缘设置的基坑围护桩的施工方法，设置于基坑和隧道之间，包括如下步骤：于所述隧道一侧间隔打设若干个第一排MJS摆喷孔，所述第一排MJS摆喷孔的深度和所述工字钢的打设深度一致；于所述第一排MJS摆喷孔注浆并形成半圆状的第一排MJS隔离桩，所述第一排MJS隔离桩的弧形段朝向所述基坑，相邻的两个所述第一排MJS隔离桩有部分重合；于所述基坑外的土体且位于所述基坑与所述隧道之间间隔打设若干个工字钢；于相邻的两个所述工字钢之间打设第二排MJS摆喷孔，所述第二排MJS摆喷孔的深度和所述工字钢的深度一致；于所述第二排MJS摆喷孔注浆以形成半圆状的第二排MJS工法桩相对设置的所述第一排MJS隔离桩和所述第二排MJS工法桩有部分重合。
