Controllable bidirectional variable porosity composite seawall experimental model

Abstract

The invention relates to a controllable bidirectional variable porosity composite seawall experimental model which comprises a dam base, a water-facing slope used for making contact with water waves is formed on one side of the dam base, a plurality of channels are formed in the surface of the water-facing slope, and a plurality of grid holes are arranged and divided in each channel; a movable partition plate capable of movably ascending and descending is arranged in each grid hole, and the grid holes can be slit by ascending the movable partition plates. A plurality of first sliding plates are overlapped on the surface of the waterside slope in a sliding manner; and after each first sliding plate translates to the opening of each grid hole in the width direction of the channel, the first sliding plate is vertically spliced with each movable partition plate below the first sliding plate so as to partially shield each grid hole. The channel size of the seawall model can be conveniently adjusted, and the porosity of the channel can be flexibly changed, so that seawall simulation research experiments with different dimension problems can be conveniently coped, various numerical simulation researches can be conveniently carried out, and scientific research work of seawall wave dissipation can be conveniently carried out.

Description

technical field [0001] The invention relates to the technical field of experimental simulation equipment, in particular to a controllable bidirectional variable porosity composite seawall experimental model. Background technique [0002] The sea wall is a kind of building specially built in the estuary and coastal area to prevent the invasion of sea tide and wind and waves and reduce the harm caused by it. Seawalls are generally set at an incline, and their fronts are mostly water-facing slopes, which are used to contact and block water waves. The surface of the water-facing slopes is generally arranged with multiple channels, which are used to eliminate water waves. [0003] However, in order to study the effect of different channel structures on the elimination of water waves, it is often necessary to build a simulation model of the seawall to conduct simulation experiments. However, due to the seabed model commonly used in the laboratory, the channel is fixed, so in the e...

Problems solved by technology

[0003] However, in order to study the elimination effect of different channel structures on water waves, it is often necessary to construct a simulation model of a seawall for simulation experiments. However, since the channel of the seabed model commonly used in the laboratory is fixed, the In the process, it is necessary to conduct experiments by replacing multiple seawall models with different channel sizes in order to obtain different experimental data, and the collection process of experimental data is cumbersome

In addition, in order to further study the wave dissipation effect of the seawall, in the research work of the seawall model, it is generally necessary to study the two-dimensional and three-dimensional problems of the seawall's response to water waves, and the study of the three-dimensional problem of the seawall is mainly used to study In fact, the effect of porosity on the effect of wave dissipation, and the study of the two-dimensional problem of the seawall is convenient for numerical model verification and mechanism research; when the two-dimensional problem needs to be considered, the distance between the channels on the seawall It should be smaller than the length of the channel, that is, the porosity of the channel needs to be larger, and when three-dimensional problems need to be considered, the distance between the channels on the seawall should be greater than the length of the channel, that is, the porosity of the channel needs to be larger. The small porosity makes the surface of the seawall's water-facing slope a porous structure, so it is necessary to use a variety of seawall models with different channel sizes to carry out research experiments on the two-dimensional and three-dimensional problems of the seawall. It further increases the complexity of the experiment, which is not conducive to scientific research work
