Underwater earthwork excavation method
The invention relates to an underwater earthwork excavation method, and relates to the technical field of water conservancy projects. The method comprises the steps that S1, a movable vehicle body drives a mounting frame to move to an area where a foundation pit is to be excavated, then a mounting mechanism drives a pile casing to move in the length direction of the mounting frame, the pile casing is made to move towards the water bottom in the vertical direction from the position over the area where desilting is completed, and meanwhile a rotating mechanism rotates to drive a cutting cylinder to rotate in the pile casing; the water bottom obtained after desilting is completed is cut, and the pile casing is conveniently inserted into the excavation area in the vertical direction till the pile casing moves to the preset depth; and S2, the bearing mechanism is rotated, earth and stone at the bottom of the pile casing are cut, and then the rotating mechanism is moved, so that the bearing mechanism drives the earth and stone in the pile casing to move out of the pile casing. The underwater pile casing inserting device has the effect that in the underwater pile casing inserting process, the pile casing is not prone to deviation in the vertical direction.
本申请涉及一种水下土石方开挖方法，涉及水利工程技术领域。其包括S1、通过移动车体带动安装架移动至带开挖基坑的区域，接着利用安装机构带动护筒沿安装架的长度方向移动，使得护筒从清淤完成的区域的正上方沿竖直方向往靠近水底的方向移动，同时旋转机构转动，带动切割筒在护筒中转动，对清淤完成后的水底进行切割，便于护筒沿竖直方向插设在开挖区域内，直至护筒移动至预设深度；S2、转动承接机构，切割护筒底部的土石方，接着移动旋转机构，使得承接机构带动护筒中的土石方移动出护筒。本申请具有在水下插设护筒的过程中，护筒在竖直方向上不易发生偏移的效果。
