Construction equipment and method for underwater anchoring foundation
The invention provides construction equipment and method for an underwater anchoring foundation, and the construction equipment comprises a penetration power head which is internally provided with a vibration motor, a jet flow sand conveying channel and a jet flow sand flushing nozzle; the shell is connected with the injection power head; the isolating membrane is connected with the shell; the pressure-resistant hose penetrates through the shell and is connected with the injection power head; the water injection component is connected with the pressure-resistant hose; the grouting component is connected with the pressure-resistant hose; the anchor cable is wrapped outside the pressure-resistant hose; the water injection component is matched with the jet flow sand conveying channel and the jet flow sand flushing nozzle to form jet flow, and seabed silt around the injection power head is fluidized through the combined action of the jet flow and high-frequency vibration of the vibration motor, so that the whole equipment is injected into a seabed by virtue of self weight; and the grouting component is used for consolidating silt near the penetrating power head, the shell, the anchor cable and the isolating membrane together by injecting slurry with a consolidation effect to form the underwater anchoring foundation. According to the invention, the penetration posture in the bottom bed is controllable, the penetration depth is controllable, and a vertical anchoring foundation can be formed.
本发明提供一种水下锚固基础的建设装备及方法，包括：贯入动力头，其内部设有振动电机、射流输沙道和射流冲沙嘴；外壳，其与贯入动力头连接；隔离膜，其与外壳连接；耐压软管，其贯穿外壳与贯入动力头连接；注水部件，其与耐压软管连接；注浆部件，其与耐压软管连接；锚缆，其包裹于耐压软管外部；注水部件与射流输沙道和射流冲沙嘴配合形成射流，通过射流与振动电机的高频振动联合作用，流化贯入动力头周围的海床泥沙，使整个装备依靠自重贯入海床；注浆部件通过注入具有固结作用的浆体，将贯入动力头、外壳、锚缆、隔离膜附近泥沙固结在一起形成水下锚固基础。本发明实现了在底床内的贯入姿态可控，贯入深度可控，可形成一个垂直的锚固基础。
