吹填造陆工程中越来越多的面对超软土的加固。通过对传统真空预压法进行改进,提出了浅层超软土地基真空预压加固技术。采用了可循环的三维土工排水网取代砂垫层作为排水垫层,解决了超软土地基砂垫层的铺设难题和天然砂石料价格上涨带动真空预压造价上涨的问题。用平板泡沫搭设的浮桥,提供了一个稳定性可以满足使用要求的作业面,实现了超软土上的材料倒运。结合浮桥搭设的隔水挡埝,实现了大面积超软土的分区加固。通过泥面铺设编织布和无纺布,实现了超软泥面打设排水板。最后给出了典型工程应用。
Dredging and land reclamation project more and more facing the super soft soil reinforcement. Through the improvement of the traditional vacuum preloading method, the vacuum preloading technology of shallow ultra-soft ground is proposed. The use of a recyclable three-dimensional geotextile drainage network instead of the sand cushion as a drainage cushion to solve the problem of laying the sand cushion of ultra-soft soil foundation and natural sand stone prices led to vacuum pre-press cost. The pontoon with slab foam provides a stable working surface that meets the requirements of use and allows for the unloading of materials on ultra-soft soils. Combined with the pontoon erection of the water barrier, to achieve a large area of ultra-soft soil partition reinforcement. Laying weaving cloth and non-woven cloth through the mud surface, to achieve a super-soft mud surface laying drainage board. Finally, the typical engineering application is given.
