Combined pile type structure and construction method for treating insufficient bearing capacity of deep foundation pit construction pile by adopting combined pile type structure
The invention provides a combined pile type structure and a construction method for treating insufficient bearing capacity of a deep foundation pit construction pile by adopting the combined pile type structure, and relates to the technical field of buildings. The technical problem in the prior art that the effect of treating the insufficient bearing capacity of the deep foundation pit construction pile by adopting an existing method is poor is solved. The combined pile type structure comprises a steel pipe pile, grouting pipes and steel pipe sleeves, and the grouting pipes are connected to the two sides of the steel pipe pile; and the bottom sections of the grouting pipes are arranged into pressure drop nozzles, the pressure drop nozzles are sleeved with the steel pipe sleeves, the bottoms of the steel pipe sleeves are blocked, and accommodating cavities are formed between the steel pipe sleeves and the pressure drop nozzles. The steel pipe pile is directly sleeved and driven in situ, the position and the size of a bearing platform do not need to be changed, the periphery of the steel pipe pile is grouted through the grouting pipes, a soil body is reinforced, the integrity of the soil body is enhanced, the bearing capacity of the steel pipe pile is effectively guaranteed, and compared with an existing construction scheme, operation is convenient and fast, social and economic effects are remarkable, the requirements for efficient, energy-saving and green construction are met, and meanwhile, the construction cost is saved.
本发明提供了一种组合式桩型结构及采用组合式桩型结构处理深基坑施工桩承载力不足的施工方法，涉及建筑技术领域，解决了现有技术中存在的采用现有方法处理深基坑施工桩承载力不足效果较差的技术问题，所述组合式桩型结构包括钢管桩、注浆管和钢管套，钢管桩的两侧均连接设置有注浆管；注浆管的底部区段设置为压降喷头，钢管套套设于压降喷头外侧，其底部封堵，钢管套与压降喷头之间形成容置腔；本发明钢管桩直接原位套打施工桩，不用改变承台位置及尺寸，通过注浆管对钢管桩周边注浆，加固土体，增强土体整体性，有效保证钢管桩承载力，相比较现有施工方案，操作便捷，社会和经济效果显著，符合高效节能绿色施工的要求，同时节约了施工成本。
