Construction method for reinforcing foundation soil body of hydraulic structure
The invention relates to a construction method for reinforcing hydraulic structure foundation soil, which comprises the following steps of: firstly, acquiring data of a to-be-constructed area, and cleaning a construction site; calculating the bearing capacity of the foundation in the to-be-constructed area; selecting each group of piling hole positions on the base soil body; selecting pile length; punching is conducted till the design depth requirement is met; the casing pipe is sunk into soil, the selected pile is placed into the casing pipe, then gravel is fed into the casing pipe, and the casing pipe is kept to be perpendicular to the foundation surface; and after the bottom end of the sleeve is separated from the hole site, gravel is laid on the pile top, and a road roller is used for repeatedly rolling for multiple times. According to the method, the pile length is reasonably selected, the cost can be saved, the stability of the foundation can be improved, in addition, the reinforcing effect is effectively improved through the double reinforcing modes, the method is easy to operate and construct, earthwork does not need to be excavated, the reinforcing anti-seepage effect is good, large machines cannot be used, the construction period is short, and the construction cost is reduced. Therefore, time cost, manpower and material resources are saved.
本发明涉及一种水工建筑物基底土体加固补强的施工方法，该方法首先获取待施工区域的资料，并对施工现场进行清理；计算待施工区域地基的承载力；在基底土体上选择每组打桩的孔位位置；选择桩长；冲孔至满足设计深度需求；将套管下沉到土壤中，向套管内放入所选择的桩，再向套管内送入碎石并保持套管垂直于地基面；在套管的底端与孔位分离后，桩顶铺上砂砾，用压路机重复碾压多次。本发明通过对桩长的合理选择，既可以节约成本，还可以提高地基的稳定性，此外，双重的加固方式，有效的提升了加固效果，此方法操作简单，施工简单，无需开挖土方，加固防渗效果较好，并且用不到大型的机械，施工周期短，从而节省了时间成本和人力物力。
