Counter-pressure system for restraining horizontal displacement of foundation pit enclosure structure and construction method thereof
The invention provides a counter-pressure system for restraining horizontal displacement of a foundation pit enclosure structure and a construction method thereof, and relates to the field of foundation pit construction in geotechnical engineering. The construction method comprises the steps that a steel bracket, a PVC reinforced water bag and a limiting block are arranged; the steel bracket is arranged at the bottom of a foundation pit; the outer side edge of a cross beam of the bottom of the steel bracket is limited by a positioning block to realize the limiting of the outer side of the steel bracket in the horizontal direction; a stand column of the steel bracket corresponds to the outer side interval of the enclosure structure; the PVC reinforced water bag is arranged between the standcolumn and the enclosure structure; and the lower end of the PVC reinforced water bag is arranged on the inner side edge of the cross beam. In the practical use process, the occupied area is small, the stability is high, the counter-pressure height is large, the counter-pressure load is large, the construction is simple, convenient and fast, the counter-pressure system is economical and practical, an application range is wide, and the counter-pressure system is suitable for being widely popularized.
本发明提供了一种约束基坑围护结构水平位移的反压体系及其施工方法，涉及岩土工程中的基坑施工领域，通过设置钢支架、PVC加筋水囊和限位块；所述钢支架设在基坑坑底；所述钢支架底部的横梁外侧边通过定位块限位，用于实现所述钢支架外侧水平方向的限位；所述钢支架的立柱与围护结构外侧间距对应设置；所述PVC加筋水囊设在所述立柱和围护结构之间；所述PVC加筋水囊下端设在所述横梁的内侧边上。本申请在实际运用过程中，占地小，稳定性高，反压高度大，反压荷载大，施工简便、快捷，经济实用，适用范围广，适合广泛推广。
