Riverbed deep-buried geological defect reinforcing treatment method
The invention discloses a riverbed deep-buried geological defect reinforcing treatment method. The riverbed deep-buried geological defect reinforcing treatment method is characterized in that throughgeological exploration, the range, burial depth, thickness and occurrence of geological defects are obtained; a plurality of shear-resistant holes are excavated in the geological defect parts at certain intervals in the direction perpendicular to a river, rock masses between the adjacent shear-resistant holes are subjected to tracing of the geological defects according to the blocking and sequencing principle by drilling guide holes, the guide holes are used for high-pressure water flushing, backfill grouting is adopted for replacement after high-pressure water flushing is completed, and thencontact grouting is adopted for reinforcement; and finally, concrete backfilling, backfilling grouting and joint grouting treatment are conducted on the shear-resistant holes. According to the riverbed deep-buried geological defect reinforcing treatment method, the reinforcing technology and dam main body engineering pouring or filling are separated in space and can be synchronously implemented intime, the linear construction period of the engineering is not occupied, the sequential block and sequential hole blocking and sequential interval construction technology is adopted in the technology, the hole collapse risk possibly existing in centralized hole opening is overcome to the maximum extent, meanwhile, useful rock masses of an original riverbed dam foundation can be utilized to the maximum extent to serve as the dam foundation rock masses, and the excavation replacement amount is greatly reduced.
本发明公开了一种河床深埋地质缺陷加固处理方法。通过地质勘探，获得地质缺陷的范围、埋深、厚度及产状；垂直于河流方向在地质缺陷部位按一定间距开挖多条抗剪洞，相邻抗剪洞间岩体按分块分序原则采用开钻引孔追踪地质缺陷并利用引孔进行高压水冲洗，高压水冲洗完成后采用回填灌浆进行置换，再采用接触灌浆进行补强，最后对抗剪洞进行混凝土回填及回填灌浆、接缝灌浆处理。本发明加固技术与大坝主体工程浇筑或填筑在空间上脱开，时间上可同步实施，不占压工程直线工期，工艺采用序块、序孔分块分序间隔施工工艺，最大可能地克服集中开孔可能的存在的塌孔风险，同时能够最大化利用原河床坝基有用岩体作为坝基岩体，大大减少开挖换填量。
