Overwater construction method for photovoltaic support foundation pile

YOU JIANGNAN

The invention discloses an overwater construction method for a photovoltaic support foundation pile, belongs to the technical field of photovoltaic support construction, and provides the following scheme that a pile driving assembly, a double-shaft motor, a screw rod, threaded seats, a first clamping plate and a second clamping plate are arranged, the screw rod is driven by the double-shaft motor to rotate, and the screw rod drives the two threaded seats to move close to each other; a first clamping plate and a second clamping plate are close to each other and enclose a foundation pile, then the foundation pile is limited through a second pulley, and the situation that the foundation pile inclines to affect the piling accuracy is prevented. After the foundation pile is limited, a lifting disc is driven by a lifting machine to take up a steel wire rope, and a movable table drives a gravity hammer to be lifted upwards; and then the lifting disc is operated through the elevator to release the steel wire rope, the gravity hammer can hammer the foundation pile downwards at the moment, piling operation can be smoothly achieved through the reciprocating operation, simultaneous construction of two pile positions can be achieved, and the construction efficiency is improved.

本发明公开了用于光伏支架基础桩的水上施工方法，属于光伏支架施工技术领域，现提出如下方案，本发明通过设置打桩组件、双轴电机、螺杆、螺纹座、第一夹板和第二夹板，通过双轴电机驱动螺杆旋转，使螺杆带动两个螺纹座相互靠近运动，使第一夹板和第二夹板相互靠近并围合在基础桩上，此时再通过第二滑轮对基础桩限位，防止基础桩发生歪斜影响打桩精准性，在完成基础桩限位后，通过提升机驱动提升盘收取钢丝绳，使活动台带动重力锤向上提起，然后通过提升机操作提升盘放出钢丝绳，此时重力锤即可向下锤击基础桩，以此往复即可顺利实现打桩作业，而且可达到两个桩位的同时施工，提高了施工效率。
