Earth excavation construction method for shallow foundation treatment in deep flow plastic sludge geology
The invention relates to an earth excavation construction method for shallow foundation treatment in the deep and thick flow plastic sludge geology, which comprises the following steps of: 1, preparing a site, lofting a curing treatment area, dividing the curing treatment area into treatment areas with preset areas; 2, quantitatively blending a curing agent, calculating the dosage ratio of the curing agent according to the soft soil engineering amount of the treatment section, and quantitatively setting the spraying rate of the curing agent; step 3, site curing treatment: uniformly stirring the in-situ soil, performing zoning stirring according to the water content of a site soil sample and the form of a curing agent, gradually performing deep stirring in the same direction, spraying the curing agent until a curing design bottom is reached, then performing stirring in a reverse direction, performing slow lifting stirring, and spraying the curing agent; and fourthly, rolling compaction and maintenance are carried out, after curing construction is completed, the construction area is flattened and compacted, and excavation construction is carried out after natural maintenance is carried out for preset days. The device has the advantages of being good in mud geological earth excavation effect, convenient to operate and high in cost performance.
本发明涉及一种深厚流塑性淤泥地质浅基础处理的土方开挖施工方法，步骤一、场地准备，将固化处理区域进行放样并划分区域，划分预设面积的处理区域；步骤二、固化剂定量调配，根据处理段落的软土工程量计算固化剂用量配比，定量设置固化剂喷料速率；步骤三、场地固化处理，对原位土进行均匀搅拌，根据现场土样含水率的高低以及固化剂形式划区搅拌，朝同一个方向逐渐深入搅拌并喷射固化剂，直至达到固化设计底部，然后反方向搅拌运行缓慢提升搅拌并喷固化剂；步骤四、碾压和养护，固化施工完毕后，对施工区域进行平整压实，自然养护预设天数后，进行开挖施工。本发明的优点是，用于淤泥质地质土方开挖效果好，操作方便，性价比高。
