Karst cave piling method under complex geological conditions
The invention discloses a karst cave piling method under complex geological conditions, which optimizes a karst cave treatment method, adopts different treatment schemes according to karst cave stratum conditions, cave sizes and karst cave filler conditions, selects a percussion drill construction process, and can better adapt to complex geological conditions, the hole forming speed is higher, the karst cave treatment time is shortened and the construction efficiency is improved compared with a rotary drilling drill. And in addition, the conditions of hole collapse, hole shrinkage and the like do not occur in the construction operation, and the hole forming quality is good. During operation, according to the slurry leakage condition, clay, stone, cement or a combination thereof is selected for backfilling treatment, the clay and the stone can be obtained locally, waste is utilized, garbage disposal is reduced, energy conservation and environmental protection are achieved, the use amount of the cement is reduced, and the treatment cost is greatly reduced.
本发明公开了一种在复杂地质条件下的溶洞打桩方法，优化了溶洞处理方法，根据溶洞地层情况、空洞大小、溶洞填充物情况采取不同处理方案，选用冲击钻施工工艺，与旋挖钻相比更能适应复杂地质情况，成孔速度更快，缩短溶洞处理时间，加快成桩速度，而且施工作业中未出现塌孔、缩径等情况，成孔质量好。操作时根据漏浆情况，选择使用粘土、石块、水泥或其组合进行回填处理，粘土、石块可就地取材，废物利用，减少垃圾弃置，节能环保，而且水泥用量减少，大大降低处理成本。
