Deepwater slope type groyne rubble installation and slope arrangement process

Abstract

The invention discloses a deepwater slope type groyne rubble installation and slope arrangement process. The segmented construction is performed for a groyne consisting of a levee crown area, a coastal side levee slope and a high seal side levee slope in the length direction from a bank side; the construction comprises rough polishing and slope arrangement of breakwater core stones, installation and slope arrangement of armor rocks and installation of armor blocks; for the construction section after the rough polishing of the breakwater core stones, firstly, the slope arrangement of the breakwater core stones and the installation and slope arrangement of at least one layer of armor rocks are performed for the levee crown area; then, a first armor rock construction platform horizontally connected with the levee crown area is built on the coastal side levee slope; and the slope arrangement of the breakwater core stones and the installation and slope arrangement of at least one layer of armor rocks are performed for the coastal side levee slope. The process is applied to segmented flow operation of an outer slope of a slope levee, converts a water construction position to land construction under the precondition of not increasing the project cost, and improves the operation efficiency.

Description

technical field [0001] The invention relates to the field of breakwater construction. More specifically, the present invention relates to a deep water slope type breakwater block stone installation and slope management technology. Background technique [0002] The construction of deep-water breakwaters generally uses barges for riprap and slope management operations. This method is suitable for construction in sea areas with good wind and wave conditions; however, construction in areas with severe wave conditions will cause serious pitching, rolling and heave due to the impact of waves sports. On the one hand, this greatly reduces the operating window of the ship and affects the work efficiency; on the other hand, it also affects the accuracy of the ship's stone installation and increases the difficulty of slope management. [0003] However, if the deep-water breakwater is constructed by land propulsion, when the embankment is wide and the sea water is deep, many positions...

[0002] The construction of deep-water breakwaters generally uses barges for riprap and slope management operations. This method is suitable for construction in sea areas with good wind and wave conditions; however, construction in areas with severe wave conditions will cause serious pitching, rolling and heave due to the impact of waves sports

On the one hand, this greatly reduces the operating window of the ship and affects the work efficiency; on the other hand, it also affects the accuracy of the ship's stone installation and increases the difficulty of slope management

[0003] However, if the deep-water breakwater is constructed by land propulsion, when the embankment is wide and the sea water is deep, many positions of the embankment may not be able to be constructed by using conventional machines; in order to meet the construction requirements, equipment with greater capacity must be selected. means greater cost, which has a significant impact on the economics of the project
