High-pressure grouting reinforcement assembly for PHC tubular pile and construction method of high-pressure grouting reinforcement assembly
The invention relates to the technical field of engineering construction, in particular to a PHC pipe pile high-pressure grouting reinforcement assembly and a construction method thereof.The PHC pipe pile high-pressure grouting reinforcement assembly comprises a pipe pile, a reinforcement cage is arranged in the pipe pile, a grouting pipe is fixedly installed on the reinforcement cage, a water return pipe is arranged on one side of the grouting pipe, a plugging layer is arranged on the lower side of the water return pipe, and a clamping block is arranged on the outer ring face of the plugging layer; one side of the clamping block is fixedly connected with a sliding block, one side of the sliding block is rotationally sleeved with a sliding rod, a driving disc is installed on the lower side of the sliding rod, and a ground base is arranged on the lower side of the driving disc; the method has the beneficial effects that the reinforcement cage is installed in the cavity, the cavity is filled with the gravel, high-pressure cement paste doped with aluminum powder and expanding agents permeates the outer side of the pipe pile through the defect part, and a bamboo joint-shaped protection layer is formed on the outer side of the defect part of the pipe pile, so that effective consolidation of original steel bars and concrete at the defect part is achieved, and the effects of reinforcement and reinforcement are achieved; the pile pressing depth can be greatly reduced, meanwhile, the foundation bearing capacity is met, the grouting device is easy and convenient to install, and cost can be effectively reduced.
本发明涉及工程施工技术领域，具体为一种PHC管桩高压注浆加固补强组件及其施工方法，包括：管桩，管桩内设置有钢筋笼，钢筋笼上固定安装有注浆管，注浆管一侧设置有回水管，回水管下侧设置有封堵层，封堵层外圈面设置有夹块，夹块一侧与滑块固定连接，滑块一侧转动套设有滑杆，滑杆下侧安装有驱动盘，驱动盘下侧设置有地面基座；有益效果为：腔内安装钢筋笼，填入碎石，采用高压力，掺有铝粉和膨胀剂的水泥浆通过缺陷部位渗透管桩外侧，并在管桩缺陷部位外侧形成竹节形保护层，从而达到缺陷部位原钢筋与混凝土的有效固结，起到加固、补强的作用，采用后注浆技术，可以大幅减小压桩深度同时满足地基承载力，注浆装置安装简便，可以有效降低成本。
