Construction method suitable for pile foundation in underground river environment
The invention belongs to the technical field of bridge pile foundation construction, and particularly provides a pile foundation construction method suitable for the underground river environment, pile foundation hole forming construction is carried out in the underground river environment and the karst cave environment, and in the pile foundation hole forming construction process, pile foundation hole forming is carried out in the mode that mud retaining wall hole forming and clear water drilling hole forming are combined; after pile foundation holes are formed, a retaining wall structure is adopted for underwater concrete pouring, and the problems that in the existing pile foundation construction organization process in the underground river environment, due to the fact that underground river space distribution and hydrological conditions are different, a single pile foundation construction scheme for karst areas is adopted, practicability and applicability are poor, resource equipment investment is large, and construction cost is low are solved. In order to solve the problems of long construction period and incapability of ensuring the pile forming quality in the prior art, the pile forming quality is ensured, the cost is saved to the maximum extent and the economic benefit is created by selecting a reasonable construction method through researching the spatial distribution and hydrological conditions of the underground river in the pile foundation construction organization process in the underground river environment.
本发明属于桥梁桩基施工技术领域，具体提供了一种适用于地下暗河环境桩基的施工方法，在地下暗河和溶洞的环境中进行桩基成孔施工，在桩基成孔施工过程中，采用泥浆护壁成孔与清水钻成孔相结合的方式进行桩基成孔；在桩基成孔后，采用护壁结构进行水下混凝土灌注，解决了现有在地下暗河环境下的桩基施工组织过程中，由于地下暗河空间分布和水文情况不同，采用单一的针对岩溶地区的桩基施工方案，实用性和适用性不好，资源设备投入大，施工周期长，成桩质量不能保证的问题，本发明在地下暗河环境下桩基施工组织过程中，通过对地下暗河空间分布和水文情况的研究，选择合理的施工方法，保证成桩质量，最大化节约成本，创造经济效益。
