Anchor rod static pressure die pipe device and cast-in-place pile construction method
The invention relates to an anchor rod static pressure die pipe device and a cast-in-place pile construction method, the anchor rod static pressure die pipe device comprises a prefabricated pile tip and a cushion cap, a die pipe assembly is movably connected to the upper portion of the prefabricated pile tip, and the axial direction of the die pipe assembly is flush with the axial direction of the prefabricated pile tip; a reinforcement cage is placed in the mold pipe assembly, the lower end of the reinforcement cage is fixed to the upper end of the prefabricated pile tip, and the mold pipe assembly and the prefabricated pile tip are pressed into the stratum through a static pressure method; the cushion cap is located above the die pipe assembly and arranged on the reinforcement cage extending out of the die pipe assembly in a sleeving mode, the lower end of the cushion cap abuts against the die pipe assembly, and the upper end of the cushion cap abuts against the jack. The method has the advantages that pile splicing is not needed, pile bodies are continuous, main reinforcements are continuous, and construction overload is avoided.
本发明涉及一种锚杆静压模管装置及灌注桩施工方法，包括预制桩尖和垫帽，预制桩尖上方活动连接有模管组件，且模管组件的轴向与预制桩尖的轴向平齐；模管组件内放置有钢筋笼，钢筋笼的下端与预制桩尖的上端固定，并通过静压法将模管组件和预制桩尖压入至地层内；垫帽位于模管组件的上方，并套在伸出于模管组件的钢筋笼上，且垫帽的下端与模管组件相抵触，垫帽的上端与千斤顶相抵触；本发明具有无需接桩、桩体连续、主筋连续、无施工过载的优点。
