Subway entrance and exit SMW construction method pile invasion treatment method
The invention discloses a metro entrance and exit SMW construction method pile invasion treatment method, a row of SMW construction method piles are constructed on the outer side of a metro entrance and exit, and the invasion treatment method comprises the steps that H-shaped steel in the SMW construction method piles at the invasion position is pulled out; high-pressure jet grouting piles are driven into the soil facing sides of the row of SMW construction method piles in a one-to-one correspondence mode, and a first row of high-pressure jet grouting piles are formed; and the pulled-out H-shaped steel is inserted into the high-pressure jet grouting pile corresponding to the SMW construction method pile at the invasion limit position, and the waterproof performance is improved while invasion limit is solved through the invasion limit treatment method.
本发明公开了一种地铁出入口SMW工法桩侵限处理方法，地铁出入口的外侧施工有一排SMW工法桩，所述侵限处理方法包括步骤：将侵限位置处的SMW工法桩内的H型钢拔除；在一排SMW工法桩的迎土侧一一对应地打入高压旋喷桩，并形成第一排高压旋喷桩；将拔除的所述H型钢插入到与所述侵限位置处的SMW工法桩对应的高压旋喷桩内，通过上述侵限处理方法解决侵限的同时，提高了防水性能。
