Static pressure composite pile construction method
The invention relates to a static pressure composite pile construction method, which adopts static pressure composite pile construction equipment, comprises a steel platform, a blowout prevention and sealing device, a static pressure pile machine and a fixed anchor rod, and comprises the following steps: firstly, fixing the steel platform on a duct piece through the fixed anchor rod, and providing counter force by a tunnel structure; and then a blowout prevention and sealing device is arranged, finally, the static pressure pile machine is in place, the static pressure anchor rod pile is pressed in, and the purpose of treating continuous settlement of the tunnel is achieved. The pile head and the tunnel structure can be effectively connected through side face pile pressing, durability special treatment is conducted, stress is guaranteed, and the water leakage risk under long-term operation is prevented and controlled; the problem that the implementation effect of original micro-disturbance grouting is not good is solved through pile pressing, and a pile body adopts the high-strength design of steel ladle concrete, so that enough anti-pressure capability can be provided; in the construction process, special blowout prevention is arranged, and risks in the construction process are avoided; a special static pressure anchor rod pile machine is suitable for the special working condition of long-distance transportation of a tunnel.
本发明涉及一种静压复合桩施工方法，采用静压复合桩施工装备，包括钢平台、防喷及密封装置、静压桩机、固定锚杆，首先，将钢平台通过固定锚杆固定在管片上，由隧道结构提供反力；然后设置防喷及密封装置，最后静压桩机就位，压入静压锚杆桩，起到治理隧道持续沉降的目的。本发明通过侧面压桩能够使桩头与隧道结构形成有效连接，并做耐久性专项处置，保证受力和防控长期运营下的渗漏水风险；通过压桩解决原微扰动注浆实施效果不好的目的，且桩身采用钢包混凝土的高强设计，能够提供足够的抗压能力；施工过程中，设置专项防喷，避免施工过程风险；特制静压锚杆桩机，适应于隧道长距离运输的特殊工况。
