River-adjacent area pile foundation hole construction method
The invention relates to the technical field of pile foundation hole construction, and provides a river-adjacent area pile foundation hole construction method which comprises the steps that surveying and lofting are carried out in a certain river-adjacent area to position a pile position, an excavation face is arranged at the pile position, downward excavation is carried out according to the arranged excavation face, and karst fissures extending in the direction away from a river channel exist in the river-adjacent area; when the excavation face descends to the position below a karst fissure, water in the river channel enters the pile foundation hole through the karst fissure, underwater concrete is poured into the pile foundation hole when the water level stops rising, the karst fissure is blocked after the underwater concrete is solidified, and the excavation face ascends to the upper surface of the underwater concrete; and the excavation face continues to be downwards excavated, if karst fissures appear, plugging is conducted according to the steps till the excavation depth reaches the designed excavation depth, and pile foundation hole construction is completed. According to the method, the underwater concrete in the pile foundation hole enters the karst fissure through the communicating vessel principle to block the karst fissure, the construction process is simple and easy to implement, and the problem of water seepage in the pile foundation hole is effectively solved.
本发明涉及桩基孔施工技术领域，提供了一种临河区域桩基孔施工方法，包括：在某一临河区域进行测量放样以定位桩位，并在桩位布设开挖面，按照布设的开挖面朝下开挖，其中：临河区域存在向远离河道方向延伸的岩溶裂隙；当开挖面下降至岩溶裂隙以下时，河道内的水通过岩溶裂隙进入桩基孔中，水位停止上升时向桩基孔内浇筑水下混凝土，水下混凝土凝固之后岩溶裂隙被封堵，而开挖面上升至水下混凝土的上表面；继续按照开挖面朝下开挖，若出现岩溶裂隙则按上述步骤进行封堵，直至开挖深度达到设计开挖深度完成桩基孔施工。本发明通过连通器原理使桩基孔内的水下混凝土进入岩溶裂隙以进行封堵，施工过程简单易实施，有效地解决了桩基孔内渗水的问题。
