Steel sheet pile and high-pressure jet grouting pile combined supporting structure and construction method
The invention discloses a combined supporting structure of steel sheet piles and high-pressure jet grouting piles and a construction method, the steel sheet piles are arranged outside a foundation pit, the high-pressure jet grouting piles comprise first high-pressure jet grouting piles and second high-pressure jet grouting piles, the first high-pressure jet grouting piles are arranged outside the steel sheet piles, and the second high-pressure jet grouting piles are arranged between the first high-pressure jet grouting piles and the steel sheet piles; the construction method comprises the following steps that S1, the surrounding environment is investigated; s2, on-site lofting, stay wire fixing; s3, high-pressure jet grouting pile construction; s4, guiding a hole by a long spiral drilling machine; s5, steel sheet pile construction; s6, the high-pressure jet grouting piles are subjected to re-grouting; and S7, the foundation pit is excavated. According to the combined supporting structure of the steel sheet piles and the high-pressure jet grouting piles and the construction method, the construction period is short, and disturbance to surrounding buildings and road surfaces is small.
本发明公开了一种钢板桩与高压旋喷桩的组合支护结构及施工方法，钢板桩设在基坑外部，高压旋喷桩包括第一高压旋喷桩和第二高压旋喷桩，第一高压旋喷桩设在钢板桩外部，第二高压旋喷桩设在第一高压旋喷桩与钢板桩之间；施工方法包括以下步骤：S1、调查周边环境；S2、现场放样拉线定点；S3、高压旋喷桩施工；S4、长螺旋钻机引孔；S5、钢板桩施工；S6、高压旋喷桩进行复喷；S7、基坑开挖。采用本发明的钢板桩与高压旋喷桩的组合支护结构及施工方法，施工周期短、对周边建筑物和路面扰动小。
