Deep foundation trench pipeline protection water stop anti-collapse construction method
The invention discloses a deep foundation trench pipeline protection water stop anti-collapse construction method which comprises the following steps: S1, according to specific part data of an underground pipeline, the specific position and height of a comprehensive pipeline are ascertained, and the number and spacing of driven round steel pipes are determined; s2, round steel pipes with the same length as the steel sheet piles are evenly driven into the comprehensive pipelines according to the gap distance between the comprehensive pipelines; s3, the center line of the steel sheet pile is measured and paid off, and a square steel pipe is used for connecting a row of round steel pipes close to the groove side with the steel sheet pile; s4, a grouting machine is used for conducting permeation grouting in the grouting area; and S5, when the strength of the to-be-grouted area reaches certain strength, trench earth excavation is conducted. According to the method, the round steel pipes are driven into the soft bottom layer to achieve the reinforcement effect, then large-range grouting is conducted to achieve the reinforcement effect, the water stopping effect is achieved, and the problem that in the soft stratum excavation process, when a municipal comprehensive pipeline transversely penetrating through a groove is encountered, groove supporting construction cannot be conducted through supporting piles is effectively solved.
本发明公开了一种深基槽管线保护止水防塌方施工方法，包括以下步骤：S1、根据地下管线具体部位数据，探明综合管线的具体位置及高度，确定圆钢管打入的数量及间距；S2、根据综合管线之间的空隙间距大小将与钢板桩长度相同的圆钢管均匀打入综合管线之间；S3、测量钢板桩中线并放线，使用一根方钢管将靠近沟槽侧各一排圆钢管与钢板桩连接在一起；S4、使用注浆机在注浆区内进行渗透注浆；S5、待注浆区强度达到一定强度，进行沟槽土方开挖。本发明通过将圆钢管打入软弱底层内，起到加筋效果，再进行大范围注浆起到加固作用，并且实现止水的效果，有效解决了在软弱地层开挖过程中遇到横穿沟槽的市政综合管线时无法采用支护桩进行沟槽支护施工的难题。
