真空预压软地基密封沟结构
摘要：
本实用新型涉及一种建筑工程结构，尤其是涉及一种真空预压软地基密封沟结构。密封沟由围堰和软土地基围成，截面形状上宽下尖，软土地基分为真空区和砂垫层，真空区和砂垫层组成密封沟的第一侧壁，第一侧壁上由内到外依次铺有土工布、密封膜。本实用新型具有设计较合理，施工成本较低，地基不易下沉，真空效率较好等特点。
摘要（英）：

The utility model relates to a constructional engineering structure, in particular to a vacuum preloading soft foundation sealing ditch structure. A sealing ditch is defined by a cofferdam and a soft foundation. The section of the sealing ditch is wide in top and sharp in bottom, the soft foundation is divided into a vacuum area and a sand cushion layer, the vacuum area and the sand cushion layer form a first side wall of the sealing ditch, and geotechnical cloths and a sealing film are paved on the first side wall in sequence from inside to outside. The vacuum preloading soft foundation sealing ditch structure has the advantages of being reasonable in design, low in construction cost, good in vacuum efficiency, and the like, and the foundation can not sink easily.
