Bridge pile foundation construction conduit method pouring process
The invention provides a bridge pile foundation construction guide pipe method pouring technology, and relates to the technical field of bridge construction, and the technology comprises the following steps: carrying out trial splicing and assembling on a guide pipe, carrying out a watertight pressure bearing test, and controlling the water pressure of the watertight test to be 1.5 times greater than the pressure of the water depth in a pile hole and 1.3 times greater than the maximum internal pressure when the wall of the guide pipe and a welding seam bear concrete pouring; after the test passes, the guide pipes are checked one by one, parameters are recorded, and the guide pipes are placed after the reinforcement cage is put down and put down into the pile hole in sequence; according to the method, a watertight pressure-bearing test is adopted to test the conduit, the maximum internal pressure when the conduit wall and the weld joint bear concrete pouring is calculated through an algorithm, and the water pressure of the watertight test is controlled to be 1.5 times larger than the pressure of the water depth in the pile hole and 1.3 times larger than the maximum internal pressure when the conduit wall and the weld joint bear the concrete pouring, so that the performance of the conduit is tested and determined. And the condition that the catheter bursts in subsequent perfusion is avoided.
本发明提供了一种桥梁桩基础施工导管法灌注工艺，涉及桥梁施工技术领域，包括以下步骤：对导管进行试拼组装，并进行水密承压试验，控制水密性试验水压大于桩孔内水深1.5倍压力，并大于导管壁和焊缝承受灌注混凝土时最大内压力的1.3倍；试验通过后，逐根检查导管并记录参数，在钢筋笼下放好后安放导管，依次下放至桩孔内；本发明采用水密承压试验对导管进行测试，通过算法计算出导管壁和焊缝承受灌注混凝土时最大内压力，控制水密性试验水压大于桩孔内水深1.5倍压力，并大于导管壁和焊缝承受灌注混凝土时最大内压力的1.3倍，由此测试确定导管的性能，确保后续灌注中导管不会出现爆裂的情况。
