Construction method of soft soil foundation
The invention relates to a soft soil foundation construction method which comprises a column hammer, the column hammer comprises a column sleeve and an inner pipe, the inner pipe is detachably connected to the column sleeve, the column sleeve is provided with a sliding groove, the inner pipe slides in the sliding groove, and the sliding direction of the inner pipe is the extending direction of the sliding groove; the method further comprises the following steps that the column hammer freely falls in the vertical direction for many times, so that a hole is formed in the foundation through the column hammer, then after the column hammer is embedded into the foundation, the inner pipe is separated from the column sleeve, the sliding groove is filled with filler, after the inner pipe is moved upwards, the inner pipe falls in the direction close to the groove bottom of the sliding groove, and the filler is tamped; and the operation is repeated until the sliding groove is filled. The sediment amount at the bottom of the hole and the situation that soil falls off from the side wall of the hole are reduced, the situation that sediment appears in the column sleeve is reduced, and therefore the influence of the sediment on the stability of a foundation is reduced, and the stability of the foundation is improved.
本申请涉及一种软土地基的施工方法，其包括柱锤，所述柱锤包括柱套和内管，所述内管可拆卸连接于柱套，所述柱套设有滑移槽，所述内管滑移于滑移槽，所述内管的滑移方向为滑移槽的延伸方向；还包括下述步骤：所述柱锤多次沿竖直方向进行自由落体，使得柱锤在地基形成孔洞，随后当柱锤嵌入地基后将内管与柱套分离，并在滑移槽内填充填料，随后上移内管后使得内管沿靠近滑移槽槽底的方向下落，并对填料进行夯实，重复此操作至滑移槽填满。本申请减少孔洞底部沉渣量以及孔洞侧壁出现泥土下落的情况，减少了柱套内部出现沉渣的情况，从而减少了沉渣对于地基稳固性的影响，提升了地基的稳固性。
