Complex geology foundation reinforcement treatment method and structure
The invention discloses a complex geology foundation reinforcement treatment method and structure. The method comprises the steps that a vibro-replacement gravel pile is constructed in a complex geology comprising a bedrock layer and a pebble layer in the direction from the pebble layer to the bedrock layer; and when the vibro-replacement gravel pile is constructed in the complex geology and encounters a large buried object and/or a large-area dissolving groove, a high-pressure jet grouting pile is constructed, so that a composite pile body formed by the vibro-replacement gravel pile and the high-pressure jet grouting pile which are in contact or overlapped arrangement is formed in the complex geology, and reinforcement treatment is carried out on the foundation of the complex geology. According to the complex geology foundation reinforcement treatment method and structure, the defect that the large buried object exists in the complex geology, the vibro-replacement gravel pile is blocked by the large buried object so that reinforcement treatment can not be carried out on the foundation of the complex geology is overcome, the defect that the material cost is high due to the fact that the vibro-replacement gravel pile needs to be filled with a large amount of gravel materials when the large-area dissolving groove exists in the complex geology is overcome; and the effect of improving the bearing capacity of the complex geological foundation and the effect of reducing the material cost are achieved.
本发明公开了一种复杂地质地基加固处理方法及结构，该方法包括：在包括基岩层和卵石层的复杂地质中沿卵石层向基岩层方向施工振冲碎石桩；当在复杂地质中施工振冲碎石桩遇到大块埋藏物和/或者大面积溶槽时，施工高压旋喷桩，以在复杂地质中形成由所述振冲碎石桩和高压旋喷桩相接触或者相交叠布置构成的复合桩体，对复杂地质地基进行加固处理。本发明克服了复杂地质中存在大块埋藏物导致振冲碎石桩被大块埋藏物阻挡而无法在所述复杂地质地基进行加固处理的缺陷，以及克服了复杂地质中存在大面积溶槽时导致需要在振冲碎石桩中填充大量的碎石材料，造成材料成本高的缺陷。具有提高复杂地质地基的承载力的效果，以及降低材料成本的效果。
