Deepwater riprapping method and equipment

Abstract

The invention provides a deep water riprap method and equipment. The equipment includes two fixedly connected barges. A riprap conduit extending into the water is installed between the two barges. The barge is equipped with a riprap conduit for transporting stone materials to stone transfer device. The riprap conduit is positioned above the riprap point with the barge, and the stone transfer device obtains the stone from the barge, and then transports the stone to the riprap conduit, and the stone falls along the riprap conduit to the riprap point. The barges are connected by a rigid structure. The rigid structure is made of steel sections, steel tubes or steel trusses. The stone transfer device is a backhoe excavator or a grab bucket excavator. The length of the riprap conduit can be adjusted according to the water depth of the riprap water area, and the radial dimension can be adjusted according to the particle size of the stone. The deep water riprap method and equipment provided by the present invention have strong wind and wave resistance, overcome the influence of water flow velocity on riprap, reduce the loss of stone materials during the throwing process, and realize accurate positioning and throwing in deep water.

Description

technical field [0001] The invention relates to a rock-throwing method and equipment, in particular to a deep-water rock-throwing method and equipment capable of accurate positioning in deep water, torrents or complicated flow field conditions. Background technique [0002] With the vigorous development of my country's water transportation and shipping industry, more and more deep-water port terminals have emerged as the times require. In order to ensure the stability of the building foundation, the port and terminal facilities mostly use riprap bottom protection to enhance the anti-scouring performance of the foundation. Most of the deep-water port wharf facilities are built in the open sea, and are restricted by the actual conditions such as water depth and current flow field. Under such conditions, if the traditional extensive stone riprap technology is used for throwing, the stone will often flow with the water after unloading from the water surface. The drifting distanc...
