Description

Permeable breakwater

Technical Field

The utility model relates to a hydraulic engineering field, concretely relates to openly formula breakwater.

Background

A breakwater is one of important hydraulic structures in harbors and offshore engineering, and is constructed in open seashore or harbor, and is generally constructed to form a sheltered water area.

In recent years, with the improvement of the consciousness of marine ecological civilization construction, the development of a novel and environment-friendly breakwater with social value and economic value is particularly important. The traditional caisson breakwater wall body is mostly arranged on a riprap foundation bed, stone consumption is high, silt can be prevented from entering a port due to the characteristic of impermeability, but the flow and exchange of water bodies inside and outside the port are difficult to realize, so that the caisson breakwater is not environment-friendly; the pile foundation type breakwater is opposite to the pile foundation type breakwater, has low manufacturing cost and simple technology, is suitable for deep water and soft soil foundations, allows water quality exchange, is environment-friendly, but can influence the berthing condition in a harbor when the permeation energy is more due to the permeability characteristic, and can not prevent silt from entering the harbor. In addition, the lower supporting structure of the pile foundation type breakwater bears most of the load borne by the structure, and the safety and the stability of the lower supporting structure can be threatened under the extreme environment; compared with a caisson breakwater, the counterfort breakwater structure has lighter breakwater body weight, can reduce the using amount of stones, shorten the construction period, reduce the construction cost and have weaker wave-breaking capacity.

Therefore, a breakwater needs to be designed, which can prevent silt from entering a port, can realize the flow and exchange of water bodies inside and outside the port, has little penetration energy, does not influence the mooring condition in the port, has extremely high stability and has stronger wave-breaking capacity.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: the utility model aims at providing a formula breakwater that passes through has solved current breakwater and has had the water flow and exchange inside and outside being difficult to realizing the harbor, perhaps can influence the berth condition in the harbor when seeing through the energy more to and the less strong problem of wave-breaking ability.

The technical scheme is as follows: the utility model relates to a permeable breakwater, comprising a base plate, the bottom plate is fixedly installed on the seabed, two sets of symmetrical and vertical walls are fixedly arranged on the bottom plate, the length of the two sets of vertical walls is the same as the width of the bottom plate, two sets of partition walls which are perpendicular to the vertical walls are arranged between the two sets of vertical walls, the two sets of vertical walls and the two sets of partition walls are integrally formed into a hollow cylinder body with a rectangular cross section, backfill is filled in the hollow cylinder body, pile foundation installation holes are arranged at four corners of the hollow cylinder body, a first pile foundation is vertically driven into the pile foundation installation holes, and the first pile foundation passes through the bottom plate and is driven into the seabed; still squeeze into the second pile foundation that two sets of symmetries set up perpendicularly on the bottom plate, the second pile foundation passes the bottom plate and squeezes into to the seabed inside, the top of second pile foundation and the top of first pile foundation all with prefabricated panel fixed connection, the fixed wave wall that is equipped with in one side of prefabricated panel.

Furthermore, grout is injected into a gap between the pile foundation mounting hole and the first pile foundation. Effectively improving the stability of skid resistance and inclination resistance of the structure.

Furthermore, the heights of the two groups of vertical walls are the same as the heights of the two groups of partition walls.

Furthermore, the height of the first pile foundation is the same as that of the second pile foundation, and the height of the first pile foundation is larger than that of the two groups of vertical walls. The air permeability of the upper part of the breakwater realizes the exchange of water bodies inside and outside the harbor; the lower part is waterproof, can prevent silt from entering a port, and effectively prevents the problem of sedimentation in the port.

Further, the backfill material is sand or waste tires. The waste materials are fully utilized, so that the cost is reduced, and the environment is protected.

Furthermore, rib plates are arranged on one sides, far away from the partition wall, of the two groups of vertical walls.

Further, the rib plate and the partition wall are arranged in a collinear manner.

Has the advantages that: compared with the prior art, the utility model, creatively fused caisson breakwater structure, counterfort breakwater structure, pile foundation permeable breakwater's advantage, make full use of each component's atress characteristics, guaranteed breakwater's wholeness and stability, breakwater lower part pile foundation provides vertical and horizontal bearing capacity, does not have the base bed of throwing stone, can only carry on simple flattening, the great reduction of degree of engineering volume, shortened the time limit for a project; meanwhile, the wave dissipation effect is good, the air permeability of the upper part of the breakwater is good, and the exchange of water bodies inside and outside the harbor is realized; the lower part is watertight, so that silt can be prevented from entering a port, and the problem of sedimentation in the port is effectively prevented; the backfill material adopts waste tires and other materials, and meets the requirements of resource saving and environmental protection; the breakwater structure is promoted to develop towards the direction of resource conservation and environmental protection to a great extent.
