Enclosure device and method for underwater operation in pier column splash zone
The invention belongs to the technical field of underwater operation enclosure, and relates to an enclosure device and method for underwater operation in a pier column splash zone, the enclosure device is a circular enclosure device formed by splicing two semicircular steel enclosure units, during construction, the circular enclosure device is arranged around a to-be-constructed pier column in a sleeving mode, each enclosure unit comprises a cofferdam and a buoyancy tank, and the cofferdam and the buoyancy tank are arranged on the periphery of the to-be-constructed pier column. The cofferdam is arranged on the inner side of the buoyancy tank, waterproof cloth is arranged on the outer side of the buoyancy tank, the upper edge of the waterproof cloth and the outer side of the buoyancy tank are tightened and sealed through a first ribbon, and the lower edge of the waterproof cloth and the surface of the pier column are tightened and sealed through a second ribbon; the device is light and simple in structure, convenient to machine and low in manufacturing cost; the device is simple in structure and convenient to construct and install on site, large auxiliary construction equipment is not needed, the device can be popularized to dry construction scenes of piers of other sizes and different underwater operation depths by adjusting the diameter and height of the pile casing and the cofferdam, and the device can be used for detailed inspection operation of underwater pier column diseases in a dry-wet transaction area.
本发明属于水下作业围护技术领域，涉及一种用于墩柱浪溅区水下作业的围护装置及方法，围护装置由两块半圆型钢制的围护单元拼装成圆形围护装置，施工时，将圆形围护装置套装在待施工墩柱周围，每块围护单元均包括围堰和浮箱，围堰置于浮箱内侧，浮箱外侧设有防水布，防水布的上沿与浮箱外侧通过第一扎带进行扎紧密封，下沿与墩柱表面通过第二扎带进行扎紧密封；该装置结构轻巧，构造简单，方便加工，造价低廉；现场施工安装方便，不需大型辅助施工机具，能通过调整护筒和围堰直径及高度推广到其他尺寸桥墩及不同水下作业深度干法施工场景中，还可以利用该装置作为干湿交易区的水下墩柱病害详细检查作业中。
