Reinforcement cage protection arm construction method for karst cave underground river pile foundation construction
The invention relates to the technical field of pile foundations, in particular to a reinforcement cage guard arm construction method for karst cave underground river pile foundation construction, which comprises the following steps: drilling a reinforcement cage guard arm; a reinforcement cage is placed in the drill hole; and concrete is injected into the reinforcement cage. The method has the following advantages that the self-made reinforcement cage protection arm is used for replacing a steel protection cylinder, the steel protection cylinder is prevented from deviating due to the effect of underground river water flow when the steel protection cylinder is lowered, and therefore the construction progress and construction safety are guaranteed. The structural design of the reinforcement cage protection arm is reasonable according to factors such as the pile diameter, the pile length and the water flow speed, and it is guaranteed that the reinforcement cage protection arm has enough strength, rigidity and stability. The steel reinforcement cage protection arm is manufactured according to the requirements of specifications and drawings, it is guaranteed that the size, the shape, the connecting mode and the like of the steel reinforcement cage protection arm meet the design requirements, the defects of deformation, cracks, poor welding and the like are overcome, and therefore the problem that the fixing position of a steel protection cylinder is not accurate due to the effect of water flow in a karst cave underground river is solved.
本发明涉及桩基技术领域，具体涉及一种用于溶洞暗河桩基施工的钢筋笼护臂施工方法，包括以下步骤：对钢筋笼护臂进行钻孔；将钢筋笼放入钻孔中；将混泥土注入钢筋笼中。本发明具有以下优点：使用自制的钢筋笼护臂代替钢护筒，避免下放钢护筒时因地下河水流的作用造成钢护筒偏移，从而保证了施工进度和施工安全。钢筋笼护臂应根据桩径、桩长、水流速度等因素进行合理的结构设计，保证其具有足够的强度、刚度和稳定性。钢筋笼护臂的制作应按照规范和图纸的要求进行，保证其尺寸、形状、连接方式等符合设计要求，避免出现变形、裂缝、焊接不良等缺陷，从而解决了由于溶洞暗河中水流的作用导致钢护筒固定位置不准确的问题。
