Description
Technical Field
[0001] This utility model relates to the field of groyne structure technology, and in particular to a groyne structure that can purify water. Background Technology
[0002] A groyne is a hydraulic structure used to regulate rivers and protect riverbanks. It connects to the riverbank at one end in a T-shape, altering the water flow and protecting the bank from direct erosion. Traditional groynes have a single function, do not consider ecological effects, are ineffective in purifying water, and lack ecological functions such as improving water quality.
[0003] With the continuous deterioration of water environment quality and the increasing demands for water quality improvement, groynes also need to develop in an ecological direction, that is, not only to protect the banks and stabilize the beaches, but also to improve water environment quality, create biological habitats and restore ecosystems. Summary of the Invention
[0004] The technical problem to be solved by this utility model is that traditional groynes have a single function, are difficult to purify water, and do not have the ecological function of improving water environment quality.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a groyne structure that can purify water quality. The three sides of the groyne structure facing the water are all provided with slopes, including a gravel layer, a calcite layer, a zeolite layer and a volcanic rock layer laid from bottom to top. The zeolite layer and the volcanic rock layer are laid at the same height. The zeolite layer is laid on the water-facing side and the volcanic rock layer is laid on the water-repelling side.
[0006] Preferably, the slope surface of the groyne structure is covered with a geogrid layer.
[0007] Preferably, the bottom of the geogrid layer is provided with a padding section, which is located at the bottom of the groyne structure and has a length of more than one meter.
[0008] Preferably, the geotextile in the geogrid layer has a longitudinal / transverse tensile strength ≥ 50 KN / m, a longitudinal / transverse tensile strength with 2% elongation ≥ 17.5 KN / m, and a longitudinal / transverse elongation with 2% elongation ≤ 15.0%.
[0009] Preferably, the overlap length between adjacent geotextiles is not less than 0.2m, and a stainless steel binding structure is provided every meter of the overlap. The stainless steel binding structure includes stainless steel wires that are continuously inserted into the geotextile in an S-shape.
[0010] Preferably, the gravel in the gravel layer has a particle size of 15-20 cm, the calcite in the calcite layer has a particle size of 8-10 cm, the zeolite in the zeolite layer has a particle size of 8-10 cm, and the volcanic rock in the volcanic rock layer has a particle size of 8-10 cm.
[0011] Preferably, the slope ratio of the slope of the groynes is 1:2.
[0012] This utility model provides a groyne structure that can purify water quality, and has the following beneficial effects.
[0013] 1. The three sides of the groyne facing the water are laid with layers of gravel, calcite, zeolite, and volcanic rock, with each layer working synergistically. The gravel provides permeability and a safe, stable, and flexible foundation for the groyne, adapting to uneven ground settlement. The adsorption properties of natural stones such as calcite reduce nitrogen and fluoride, improving water purification efficiency. The adsorption properties of zeolite purify the water, adsorbing impurities and toxic gases from the water source, thus achieving water purification. The volcanic rock is rich in minerals and has a porous structure that is conducive to microbial habitation, effectively degrading pollutants. This multi-layered filtration and purification of the water flow significantly improves the quality of the water environment.
[0014] 2. Geogrids fix the individual stones in place to prevent them from rolling off and improve the overall integrity of the groynes. Attached Figure Description

[0021] like Figure 1-4 As shown, this utility model provides a groyne structure that can purify water quality. The three sides of the groyne structure facing the water are all provided with slopes, including a gravel layer 1, a calcite layer 2, a zeolite layer 3, and a volcanic rock layer 4 laid from bottom to top. The zeolite layer 3 and the volcanic rock layer 4 are laid at the same height, with the zeolite layer 3 laid on the water-facing side and the volcanic rock layer 4 laid on the water-repelling side.
[0022] The structure of the groyne is shown in the figure, and will not be described in detail again. The following focuses on the requirements and functions of each part.
[0023] The groynes are all filled with filter stone to facilitate water seepage between the media, so that the water flow is in a subsurface state and forms a uniform water distribution.
[0024] The internal filling material, from top to bottom, consists of zeolite (0.5m thick), volcanic rock (0.5m thick), calcite (0.8m thick), and gravel (1.2m thick), with a dam crest elevation of 2.95m.
[0025] When constructing groynes, it is important to ensure that the bottom layer is gravel with a particle size of 15-20cm, the middle layer is calcite with a particle size of 8-10cm, and the top layer is zeolite with a particle size of 8-10cm.
[0026] Geogrid: The groyne system slope is wrapped with geogrid, which is TGSG50-50, 4*4cm in size, with longitudinal / transverse tensile strength ≥50KN / m, longitudinal / transverse tensile strength with 2% elongation ≥17.5KN / m, and longitudinal / transverse elongation with 2% elongation ≤15.0%.
[0027] When laying geogrid, the underlying stones should be flat and compacted. Generally, it should be laid flat and straight, without curling or twisting. The overlap length between two adjacent geogrid sheets should not be less than 0.2m, and the overlap should be connected with stainless steel wire every 1 meter. The entire laying surface should be flat, with uniform tightness, and the ends should be firmly anchored.
[0028] Stone materials: The main stone materials used are gravel, zeolite, calcite, volcanic rock, and pebbles. The particle size and density of the filling stone materials should meet the design requirements, as detailed in the table below.
[0029]
[0030] Gravel, zeolite, calcite, volcanic rock, and pebbles are available; please refer to the table above for specifications and dimensions. Larger stones should be placed on the outer side to prevent them from falling off. Filling must be done sequentially, evenly, and in batches; it is strictly forbidden to fill the entire area at once. When using manual filling, the thickness of each batch should be controlled to be below 35cm; when using mechanized filling, the thickness should be controlled to be 25-30cm for even distribution.
[0031] Zeolite is used to purify water by adsorbing impurities and toxic gases from the water source.
[0032] Volcanic rock can activate ions in water (primarily increasing the oxygen ion content) and can slightly release infrared rays, thus acting as a disinfectant. The porous structure of volcanic rock can adsorb harmful bacteria and heavy metal ions that affect organisms in the water. The trace elements released by volcanic rock can promote the metabolism of animal cells and remove harmful halides from the body, clearing impurities from cells. The porosity and high surface area of volcanic rock provide an excellent breeding ground for nitrifying bacteria, increasing their numbers.
[0033] By utilizing the adsorption properties of natural stones such as calcite, nitrogen and fluoride are reduced, thus improving water purification efficiency.
[0034] Gravel acts as a permeable material and provides a safe and stable flexible groyne foundation to accommodate uneven settlement of the foundation.
[0035] Geogrids fix the individual stones in place, preventing them from rolling off and improving the overall integrity of the groynes.
