Construction method for in-situ solidification of quicksand and mucky soil
The invention relates to a construction method for in-situ solidification of quicksand and mucky soil, which comprises the following steps: arranging piles on a straight line section of a to-be-constructed road at intervals of a first preset interval, arranging piles on a horizontal curve section of the to-be-constructed road at intervals of a second preset interval, and arranging indication piles on the edges of curing agent treatment layers on two sides of the to-be-constructed road; calculating the amount of required dry soil, cement consumption and curing agent consumption, and mixing the dry soil, cement and curing agent into a mixture; conveying the mixed mixture to a road to be constructed for paving, and leveling by using a land leveler; when the water content of the mixture is the optimal water content, a road roller is used for rolling to form a curing treatment layer; the curing treatment layer is subjected to water spraying maintenance; cement is doped into surface soil, and then a soil stabilizer is doped, so that the strength, the water stability and the durability of a foundation are improved; and meanwhile, compared with a traditional treatment method, the construction period is shortened, the construction efficiency is improved, and the construction cost is reduced.
本发明涉及一种流沙及淤泥质土就地固化的施工方法，包括以下步骤：在待施工道路的直线段每间隔第一预设间距设置一桩，在待施工道路的平曲线段每间隔第二预设间距设置一桩，在待施工道路的两侧固化剂处理层边缘设指示桩；计算出所需干燥土数量、水泥用量以及固化剂用量，将干燥土、水泥以及固化剂拌和成混合料；将拌和好的混合料运到待施工道路中进行摊铺，用平地机整平；当混合料的含水量为最佳含水量时，用压路机进行碾压形成固化处理层；对固化处理层进行洒水养护；通过将表层土壤掺入水泥，再掺入土壤固化剂，提高地基的的强度、水稳定性以及耐久性；同时，与传统的处理方法相比，缩短了施工工期，提高了施工效率，降低了施工费用。
