Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of plant sand dune, especially a device for constructing coastal artificial plant sand dune. BACKGROUND

[0002] Coastal sand dunes are formed under the joint action of wind and sea waves, and sand dunes have good effects on preventing sand loss, reducing the energy of sea waves, reducing the impact of sea waves on the coast, and protecting the stability of the coast. If plants grow on the sand dunes, the sand dune surface is covered with plants, forming shrub and grass sand dunes. Plants have a certain sand-fixing effect, which is beneficial to the settlement of sand and prevents sand loss. Moreover, plants can further weaken the energy of sea waves and have a better effect on protecting the coast.

[0003] In the desert, artificial sand dunes are constructed by setting sand-blocking nets, grass squares, and planting plants to slow down the movement of sand dunes and wind-sand disasters. On the coastal beach, a Chinese invention patent, a method for repairing and maintaining coastal sand dunes (CN116368983A), uses the method of artificial sand piling to form a sand pile and then plants plants. This method has a large amount of engineering and will damage the sand extraction point. The sand dune formed by artificial piling is not stable and is easily carried away by tidal water, sea waves, and wind. A wind and sand blocking structure for coastal sand dune afforestation (CN219612681U) is used to build a wind and sand blocking structure on the sand dune to resist strong salt sea wind and sea sand, improve the survival rate of green plants, protect coastal vegetation, and enhance the stability of the afforested sand dune. Plants are also planted to cover the sand dune and reduce sand loss, which plays a role in stabilizing the sand dune.

[0004] However, shrub and grass sand dunes are often affected by strong winds or tidal water before they are formed, causing the sand dune to be in an unstable moving state. Unstable sand dunes make it difficult for plants to grow, especially near the high tide line. Plants can only grow on the top of the sand dune because the flooding time is short. The moving sand dune is not conducive to plant growth.

[0005] Measures to prevent sand dune loss include placing stones at the base, covering the sand dune surface with a net or cloth, and other methods. Placing stones may cause damage to the beach. Covering the sand dune surface with a net or cloth makes it difficult for plants to grow through the holes in the net or cloth. Therefore, a device for constructing a coastal artificial plant sand dune is needed. UTILITY MODEL CONTENTS
