旋挖灌注桩水下混凝土施工质量简析

Brief Analysis of Underwater Concrete Construction Quality of Rotary Excavation Cast-in-Place Pile

摘要: 从影响灌注桩质量因素方面，多角度诠释了导管法灌注桩水下混凝土的配和比设计、拌合物工作性控制、施工工艺、关键路线。结合实际工程，钻孔灌注桩水下混凝土施工过程中，施工人员需在实际操作过程中按照设计方案严格操作，对各环节的工作质量进行严格把控，避免因为质量问题引起的二次返工。同时，施工单位也要对规章制度、人员、技术方案和原材等方面做好保障。从而保证灌注桩的成桩质量，确保整个工程的施工质量。

Abstract: From the factors affecting the quality of cast-in-place pile, in this paper, the distribution and ratio design of underwater concrete of cast-in-place pile by pipe method are interpreted from many angles, workability control of mixture, construction technology, key route. Combined with practical engineering, in the process of underwater concrete construction of bored cast-in-place pile, the construction personnel need to operate strictly according to the design plan in the actual operation process, strictly control the work quality of each link to avoid secondary rework caused by quality problems. Meanwhile, the construction unit should also pay attention to the rules and regulations, and ensure the personnel, technical solutions and raw materials, so as to ensure the quality of the cast-in-place pile and the construction quality of the whole project.
