Description

Technical Field

[0001] The invention relates to the technical field of ecological transformation of seawalls, and in particular to a tile-type oyster reef ecological slope protection prefabricated block structure and a construction method thereof. Background Art

[0002] Oyster reefs are a type of biological reef formed by a large number of oyster species attached to the surface of hard substrates and accumulated over a long period of time. They are widely distributed in the intertidal and shallow subtidal zones of temperate and subtropical regions. Oyster reefs can provide shelter, foraging, reproduction and growth environments for many marine organisms. In addition, oyster reefs also have functions such as water purification, energy coupling, coastal protection, and carbon sequestration, playing an important role in maintaining the stability of coastal ecosystems. However, due to factors such as overfishing, coastal development, and deterioration of the marine environment, 85% of the world's oyster reefs have degraded and disappeared, and most of my country's oyster reefs are facing the dilemma of functional extinction.

[0003] At present, artificial oyster reefs have been widely used in intertidal ecosystem restoration and seawall ecological transformation at home and abroad, and have achieved good results. However, the existing artificial oyster reefs have certain shortcomings in terms of structure and stability. For example, after construction, the reef body has poor stability against waves and currents, weak wave-breaking and flow-slowing capabilities, and poor biological attachment performance.

[0004] Therefore, the applicant has found a solution to the above-mentioned problem through beneficial exploration and research, and the technical solution to be introduced below is produced in this context. Summary of the invention

[0005] One of the purposes to be solved by the present invention is to provide a tile-type oyster reef ecological slope protection prefabricated block structure to solve the above problems in view of the shortcomings and defects of the prior art.

[0013] In a preferred embodiment of the present invention, the plug plate is in a long strip structure, and the plug plate and the other end of the arc plate are integrally formed.

[0014] In a preferred embodiment of the present invention, the wave-breaking slope protection is a dry-stone, mortar-stone or cast-stone structure, and its top elevation is located near the average high tide level.

[0015] In a preferred embodiment of the present invention, two adjacent prefabricated slope protection blocks are connected to form a whole by engaging a plug plate in a groove on the toe plate.

[0016] In a preferred embodiment of the present invention, the plurality of prefabricated slope protection blocks are arranged in a tile-like structure.

Vibration equipment is used for vibration. When the concrete pouring reaches more than 24 hours and its surface and edges are not damaged by demolding, demolding is carried out to produce prefabricated slope protection blocks that meet the design;

[0019] 2) Maintenance of prefabricated slope protection blocks: Use geotextile covering and spraying maintenance, and require moisturizing and covering maintenance for at least 7 days. When the strength of the prefabricated slope protection blocks reaches 70% of the design strength, they can be hoisted and stored, and when they reach 100% of the design strength, they can be transported to the construction site;

[0022] 5) Installation of prefabricated slope protection blocks: Prefabricated slope protection blocks should be installed according to the pre-arranged construction control network. The laying should be carried out from bottom to top. The two adjacent prefabricated slope protection blocks should be tightly fastened and the seams should be aligned. After laying, the slope surface should be flat and beautiful.

[0023] Due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0024] 1. The present invention adopts a snap-fit ​​connection method between adjacent prefabricated slope protection blocks to enhance the overall stability of the oyster reef ecological slope protection structure under the combined action of waves and water flow.

[0026] 3. The present invention adopts concrete with shells as aggregates. The surface of the prefabricated slope protection block is made rougher by embedding a proper amount of shell fragments, making it easier for oysters and other organisms to attach and grow. At the same time, the cavity structure of the prefabricated slope protection block also provides a rich habitat for organisms such as oysters, which is conducive to increasing the biodiversity of the area.

[0027] 4. The present invention has a simple structure and can be prefabricated in a prefabrication yard and directly installed on site. The quality of the blocks is easy to control and the construction efficiency is high.
