通过现场试验研究,开发了盲管连接自密封真空预压加固超软土新技术。该技术是一种吹填超软土表层硬壳快速形成技术,适合新近吹填的高含水率疏浚土。新技术以表层淤泥作为密封层,取消了用作施工垫层的土工布、黑砂垫层、水平排水砂垫层和密封膜,施工工艺更为简洁、环保,具有良好的应用前景。
通過現場試驗研究,開髮瞭盲管連接自密封真空預壓加固超軟土新技術。該技術是一種吹填超軟土錶層硬殼快速形成技術,適閤新近吹填的高含水率疏浚土。新技術以錶層淤泥作為密封層,取消瞭用作施工墊層的土工佈、黑砂墊層、水平排水砂墊層和密封膜,施工工藝更為簡潔、環保,具有良好的應用前景。

A new soft soil foundation improvement technique named as self-sealing vacuum preloading technique with blind pipe connection is researched and developed through filed tests. This technique is used to form a hard shell on the surface of the ultra-soft soil, suitable for newly hydraulic reclaimed dredged fill with high water content. The new technique uses the surface mud for sealing layer, cancels the soft, black sand cushion, sand cushion of horizontal drain and plastic film for air sealing, which are used as construction layer. The construction process is simple and beneficial to environment with good prospects for practice application.
