Description

Flexible protection system for promoting silt and making land near nature

Technical Field

The utility model belongs to the technical field of the ecological environment of coast is administered, concretely relates to nearly natural flexible protection system who promotes silt and make land.

Background

Coastal erosion with global trends has generally attracted attention in marine disasters. Coastal erosion refers to a destructive process of coast retreat caused by that supply of sand along the shore is less than loss of sand along the shore under the action of ocean power. 25% of the coasts in the united states are of the severe erosion type. The annual rate of change of 66% of the shorelines in japan exceeds 1 m. Nearly 70% of sandy coasts and some silt coasts in our country are also subject to erosion to varying degrees and thereby cause environmental hazards such as beach erosion, land area reduction, coastal depressions submerged, sea water irrigation, near shore building and facilities destroyed. Therefore, it is necessary to develop a suitable siltation promotion and land building method for sandy coasts and islands.

In order to alleviate the damage caused by coast erosion, the currently used method is to change the migration pattern of the near-shore silt in a local coast section through engineering measures so as to accumulate the silt. The main protection projects include the following:

firstly, the seawall is a traditional human coast protection method, is built in a higher region of a beach, is a building for dividing a seashore land area and a sea area, and generally runs parallel to a coastline. Although it plays a great role in fixing the coast and preventing moisture and waves. It is not generally applicable to the conservation of beach and is not suitable as a long-term protection against waves unless it is used as an aid or emergency under other engineering measures. Therefore, the engineering structure is generally only suitable for the coast with small sea waves or the coast silted to prevent abnormal sea sinking;

the spur dike and the spur dike group are coastal buildings which are nearly vertical to a coastline, and have the function of intercepting the silt which is transported from the upstream of the coast to form a wide beach to protect the coast. The spur dike is mature in the muddy coast and can be applied to the muddy coast region. The spur dike and the spur dike group achieve the aim of protecting the coast by the intercepted silt, so that the spur dike is not beneficial to intercepting a large amount of silt to form a beach for rivers such as yellow river with the annual reduction of the sand transportation amount, and the protection method has the defects, particularly for sandy coast;

and thirdly, constructing a breakwater approximately parallel to the shoreline in a sea area at a certain distance outside the shoreline, wherein the breakwater is called an offshore breakwater and is called the offshore breakwater for short. It acts like a spur dike and can cause siltation of the beach on the upstream side of the bank. Boulders or various concrete blocks may be used as the facing. However, the opening of the offshore bank is small, and the pollution is easy to accumulate in the bay and is difficult to discharge. Therefore, the problem of environmental pollution should be considered when selecting the offshore bank as the coastal protection project;

fourthly, the artificial river beach is used for supplementing sand, and collecting proper sand from the sea or on land to supplement the sand on the eroded beach is the most natural countermeasure for solving the coastal erosion. Beach sand replenishment has proven to be an economically effective measure and has less impact on downstream beaches than other protective facilities. Because the sand artificially filled on the beach can still be washed under various marine environmental conditions, particularly under the action of sea waves, the beach must be replenished every few years.

Although the coastal protection projects have more forms, the coastal protection projects have respective defects, and by combining the above analysis, the coastal protection projects have the advantages that firstly, except the fourth artificial beach sand supplementing measure, other measures are all arranged in seawater, so that the sand above a climax line is not protected, and sand grains can still be brought into the seawater by wind erosion; secondly, various dams play a role in reducing waves and depositing silt to the bank, but a large amount of sea sand is still washed and brought back to the sea, and both sides of the dams play a role in blocking the silt, so that the supply amount and the depositing effect of the silt on the bank are weakened; in addition, various dams are rigid structures, only one dam is arranged, waves passing through the dam have large energy and can erode the coast at any time, and the dams are high in cost and long in construction period.
