Grouting cast-in-place pile construction method for complex geology
The invention belongs to the technical field of complex geological construction, and particularly relates to a complex geological grouting cast-in-place pile construction method which comprises the following steps: step 1, tamping the complex geological ground; secondly, the compacted ground is subjected to preliminary drilling, reaming is conducted after drilling is completed, and drilling construction continues after reaming is completed; 3, hole cleaning treatment is carried out; compared with the prior art, by drilling in the soft soil layer and adopting bottom expanding construction at the joint of the hard soil layer and the soft soil layer, the bearing capacity of the pile foundation can be greatly improved under the condition of the same pile length, and the pile length can be reduced, the construction efficiency can be improved and the construction cost can be reduced under the condition of ensuring the same pile foundation bearing capacity.
本发明属于复杂地质施工技术领域，具体涉及一种复杂地质的注浆灌注桩施工方法，包括以下步骤：步骤一：对复杂地质的地面进行夯实处理；步骤二：对夯实后的地面进行初步钻孔，钻孔结束后进行扩孔，扩孔结束后再继续钻孔施工；步骤三：清孔处理；步骤四：注浆灌注桩施工，相对于现有技术，通过在软土层进行钻孔，在硬土层和软土层交接位置处采用扩底施工，能够在同样桩长的情况下可大大提高其承载力，也能够在保证相同桩基承载力的情况下减少桩长，提高施工效率，降低施工成本。
