Shallow sea region land and sea mixed rock riprap method for dynamic planning

Abstract

The invention discloses a shallow sea region land and sea mixed rock riprap method for dynamic planning. The method comprises the following steps of: (1) performing construction preparation, dividing construction grids through a beacon machine, and measuring and controlling the position of a rock riprap ship through global position system (GPS); (2) performing opening body barge rock riprap construction when the water depth is more than 1m, performing flat plate barge rock riprap construction when the water depth is close to 1m, and coordinating the two ships to perform seaborne rock riprap embankment fill; (3) performing vertical riprap construction through a land low tide or when the riprap embankment is exposed out of the water surface; (4) performing water depth and settlement observation in real time, combining the tide information, and dynamically planning the rock riprap position and the rock riprap quantity; and (5) employing a large-side small-middle rock riprap method in the total rock riprap process, and performing impact rolling reinforcement on the embankment after the rock riprap is finished. According to the method, the construction period can be effectively shortened, the construction safety is improved, the possibility of error riprap and erosion is reduced, and the construction cost is greatly reduced.

Description

technical field [0001] The technical field of land reclamation designed by the present invention, more specifically, is a method of mixing land and water riprap in shallow sea areas. Background technique [0002] With the development of the economy, the southeast coast has begun to build bay-type cities, and many offshore tidal areas have become development areas. It can be expected that coastal cities will begin to plan and build a large number of coastal roads, including a large number of offshore tidal area roads. Due to the wide sea surface, the cofferdam drainage scheme cannot be adopted for the construction of the coastal dredging road, so the subgrade is mainly made of riprap. The existing rock-throwing method does not fully consider the characteristics of water depth and tides, and the position of the rock-throwing cannot be accurately determined. The whole process only uses the same kind of rock-throwing boat. As the rock-throwing proceeds, the rock-throwing boat of...
