Prestressed high-strength concrete (PHC) pipe pile prefabricated filling core reinforcing structure and construction method
The PHC pipe pile prefabricated filling core reinforcing structure comprises a pipe pile, a filling core structure, a grouting material and a grouting structure, the pile foundation damaged position of the pipe pile is filled with the filling core structure, the filling core structure is a prefabricated cylindrical reinforced concrete structure, steel plate strips are obliquely inserted into the periphery of the filling core structure, a perforated steel plate is pre-embedded in the top of the filling core structure, and the grouting material is arranged in the grouting structure. A flat hole is formed in the lower portion of the core filling structure, a through hole is formed between the perforated steel plate on the top of the core filling structure and the flat hole in the bottom of the core filling structure, a circle of grout stopping ring is arranged below the flat hole around the lower portion of the core filling structure, and grouting materials are filled between the core filling structure and the inner wall of the pipe pile. The core filling structure can be filled to the specific damaged position of the pipe pile according to needs, the steel plate strips are arranged on the periphery of the core filling structure, after the core filling structure is lowered into the pipe pile, the steel plate strips deform to achieve the friction effect with the inner wall of the pipe pile, the core filling structure can be fixed to any position, local construction is achieved, the using amount of core filling materials is small, maintenance time is short, and the construction process is simple; and the pipe pile construction speed is greatly increased.
一种PHC管桩预制填芯补强结构及施工方法，包括管桩、填芯结构、灌浆料和注浆结构，填芯结构填塞在管桩的桩基破损位置，填芯结构为预制圆柱钢筋混凝土结构，填芯结构的周围倾斜插入钢板条，填芯结构的顶部预埋带孔钢板，填芯结构的下部开设有平孔，填芯结构从顶部的带孔钢板到底部的平孔间设置有通孔，填芯结构的下部周围在平孔的下方设置一圈止浆环，填芯结构与管桩内壁之间填充灌浆料。本发明的填芯结构可根据需要填塞至管桩特定的破损位置，填芯结构外周设置钢板条，填芯结构下放到管桩内后，钢板条变形起到与管桩内壁的摩擦作用，可使填芯结构固定到任意位置，局部施工，填芯材料用量少，养护时间短，施工过程简单，大大提高管桩施工速度。
