Collapsible loess curing construction method
The invention discloses a collapsible loess solidification construction method which comprises the following steps: detecting the soil texture of a ground to be constructed, and determining the position of a foundation for the ground to be constructed; the cylindrical steel pile pipe is driven into an original foundation, a pile hole is formed after the cylindrical steel pile pipe is pulled out, and then prepared plain soil, lime soil, lime soil, cement soil and other materials are backfilled; a heavy hammer falls from a certain height to tamp a soil layer, and after repeated tamping, a position is selected again for punching; materials such as cement and lime are injected into the hole filled with the reinforcement cage, and the hole is stirred through a deep stirring machine; deep-layer punching is conducted at the position close to the concrete column pile, and a compaction pile is formed by ramming the steel pipe into the upper portion of the expansion material through a ramming method; according to the method, construction is easy, the construction period is short, the purposes of removing water in the foundation and secondarily compacting the deep foundation through water absorption expansion of the expansion material can be achieved, and the good control effect on settlement and deformation of the collapsible loess foundation is achieved.
本发明公开了一种湿陷性黄土固化施工方法，包括如下步骤：对需要施工的地面土质进行检测，对需要施工的地面确定地基的位置；把圆柱形的钢质桩管打入原地基，拔出后形成桩孔，然后将准备好的素土、灰土、石灰土、水泥土等物料进行回填；通过重锤自一定高度下落夯击土层，反复夯实后再次选定位置进行打孔；往装钢筋笼的孔内注入水泥和石灰等物料并利用深层搅拌机对孔内进行搅拌；在混凝土柱桩附近位置处深层打孔，在利用夯实法把钢管夯入膨胀材料的上方形成挤密桩；该发明施工简单、工期短，能达到地基内部除水、通过膨胀材料的吸水膨胀二次挤密深层地基的目的，对湿陷性黄土地基的沉降、变形具有很好的控制效果。
