Embodiment Construction

[0020] see figure 1 , On the boundary of the windward side 11 of the wave-dissipating protection area, a wooden fence with a permeability of 10% to 30% is set with raw wood piles 6, steel bars 5 and other materials, and the propagation of waves to the protection area 1 is limited by reflection and breaking waves. The height of the wooden fence-type wave-dissipating belt should be slightly higher than the maximum peak height at the highest water level of 10°; The sinking bottom 3 is mostly sandy, the diameter of the small head of the wooden pile should be greater than 100mm, and the depth of driving into the lake bottom should not be less than 2m. In order to prevent waves from eroding the bottom of the lake before and after the fence-type wave-dissipating belt, sandbags 4 are pressed on both sides of the fence-type wave-dissipating belt to protect the lake bottom, so as to increase the stability of the wave-dissipating belt. Use large-scale wooden piles as the backbone piles ...

Abstract

An overall wave suppression method on lake beaches characterizes that on the front wave beaten zone protective screens are set to reduce over 70% wave energy, at the same time wave asorption zones are set along the rigid lake bank to elimiante reflection waves to stabilize the near water to promote silt up of mud and sand and formation of shoals, reset up and forms natural ecological screens, the wave suppression devices are removed including a wood fence wave suppressing zone, a net flexible wave suppressing zone, an artificial wave suppressing zone before bank.

Description

technical field [0001] The invention relates to the implementation of environmental regulation and ecological restoration on the shore of a lake, in particular to a comprehensive method and device for eliminating waves along the shore of a lake, belonging to the technical field of water environment engineering. Background technique [0002] In large lakes, wind and waves are a certain destructive hydrodynamic phenomenon, which often cause erosion and collapse of the lakeshore, endangering the safety of the lives and property of residents outside the embankment. The wave-dissipation engineering technology aimed at protecting embankments is quite mature, and it is widely used in oceans, rivers, and lakes. However, the engineering technology for protecting shallow water areas along the coast from wind and wave erosion is quite poor. The existing several types belong to The nature of embankment to keep out waves, such as block stone revetment or con...
