2results about How to "Good wave dissipation effect" patented technology

The utility model relates to the technical field of ocean engineering, in particular to a double-layer perforated plate flow guide breakwater which comprises a connecting pile and a double-layer perforated flow guide plate. Each connecting pile comprises a pile cap, a pile body and a cattle foot; the two groups of double-layer perforated guide plates are arranged in parallel front and back, each group comprises a plurality of perforated guide plates, each perforated guide plate is provided with a plurality of holes, the perforated guide plates in each group are connected into a whole side by side through the connecting piles, and the connecting piles are positioned on two sides of the perforated guide plates. According to the structure, through the optimized design, the wave dissipation effect and the structural stability of the breakwater are improved, and meanwhile the construction difficulty and cost are reduced. The structure is particularly suitable for ports, wharfs and coastal protection in the marine environment.

The utility model relates to the technical field of water conservancy cofferdams, in particular to a cofferdam body unit of a cofferdam. The cofferdam body unit provided by the utility model has good wave dissipation performance and stable performance, and comprises a cofferdam wall body, an auxiliary supporting part, a wave dissipation module and an extension part, wherein the cofferdam wall body, the wave dissipation module and the extension part form a concave upstream face, the concave upstream face can play a role in wave dissipation and flow guide on waves, and the upper layer holes and the lower layer holes which are evenly distributed in the cofferdam wall body are matched, so that water flow can be evenly distributed, and the impact effect of the water flow on the cofferdam body and the cofferdam area is reduced; furthermore, a cavity is further formed in the top of the cofferdam wall body and filled with solid filler, and the comprehensive effects of reducing the self weight, purifying water, reducing the cost, stopping silt loss, reutilizing solid waste and the like can be achieved at the same time; in addition, a pendant of a two-section type bevel structure is further arranged on the lower portion of the extending portion, oyster adsorption and fixation are facilitated, and the cofferdam body is secondarily reinforced through biological glue.
