Vacuum pressure suction cofferdam adopting soft soil in-situ consolidation and construction method of vacuum pressure suction cofferdam
The invention discloses a vacuum pressure suction cofferdam adopting soft soil in-situ consolidation and a construction method thereof, and relates to the technical field of foundation treatment.The vacuum pressure suction cofferdam comprises a cofferdam body formed by piling muddy soil and vacuum drainage reinforced cloth composed of geotechnical cloth and a plurality of drainage belts fixed to one side of the geotechnical cloth, and the vacuum drainage reinforced cloth is connected with a vacuum system; the cofferdam body is completely wrapped by vacuum drainage reinforced cloth, and the vacuum drainage reinforced cloth pumps out moisture of mucky soil in the cofferdam body through a vacuum system connected with the vacuum drainage reinforced cloth. The form that the in-situ mucky soil is integrally wrapped to form the cofferdam is adopted, the overall stability of the cofferdam can be guaranteed, the procedure is simple, and labor and construction cost is saved; and meanwhile, the vacuum drainage reinforced cloth is matched to achieve overall consolidation of the mucky soil, drainage consolidation of the cofferdam body can be achieved, the reinforcement effect on the cofferdam body can be achieved, and the effect of improving the stability and strength of the mucky soil when the mucky soil serves as the cofferdam is achieved.
本发明公开了一种采用软弱土原位固结的真空吸压围堰及其施工方法，涉及地基处理技术领域，包括由淤泥质土堆成的围堰体、由土工布以及固定于土工布一侧的若干排水带组成的真空排水加筋布，真空排水加筋布连接有真空系统；围堰体由真空排水加筋布全面包裹，真空排水加筋布通过与其连接的真空系统，将围堰体中淤泥质土的水分抽出。本发明采用对原位淤泥质土整体包裹形成围堰的形式，不仅可保证围堰整体稳定性，而且工序简单，节省人工和施工成本；同时配合真空排水加筋布实现对淤泥质土的整体固结，不仅能实现对围堰体的排水固结，还能起到对围堰体的加筋作用，具有提高淤泥质土在作为围堰时的稳定性和强度的效果。
