Embodiment 1

[0031] Example 1. refer to figure 1 . A crescent-shaped artificial island construction method, its steps are as follows:

[0032] (1) In near-shore shallow seas where the water depth does not exceed 30 meters, the positions of the headlands on both sides of the crescent-shaped artificial island are selected according to the design requirements, and the seabed at the positions of the headlands on both sides is dredged; The top is filled with stonework and cement component blocks to form headlands on both sides that are 3 meters above the high tide level;

[0033](2) After forming the headlands on both sides, fill them with bagged sand, connect the inner sides of the two sides of the headlands to form a crescent bay arc; then connect the outer sides of the two sides to form a crescent back arc; The area between the crescent-shaped bay arc and the crescent-shaped back arc is filled, drained, compacted, and raised to a height of 3 meters above the high tide level, forming a cre...

Embodiment 2

[0035] Example 2. refer to figure 1 . A crescent-shaped artificial island construction method, its steps are as follows:

[0036] (1) In near-shore shallow seas where the water depth does not exceed 30 meters, the positions of the headlands on both sides of the crescent-shaped artificial island are selected according to the design requirements, and the seabed at the positions of the headlands on both sides is dredged; Cement component blocks and stonework are used to throw and fill the upper part to form headlands on both sides that are 5 meters above the water surface at high tide;

[0037] (2) After forming the headlands on both sides, fill them with bagged sand, connect the inner sides of the two sides of the headlands to form a crescent bay arc; then connect the outer sides of the two sides to form a crescent back arc; The area between the crescent-shaped bay arc and the crescent-shaped back arc is filled, drained, compacted, and raised to a height of 5 meters above the...

Abstract

The invention relates to a method for building a crescent man-made island, which comprises the following steps: selecting the seabed in the positions of capes on two sides of the crescent man-made island in the offshore and shallow sea with the water depth of not exceeding 30m for performing desilting treatment; then performing riprap filling on the basis of the desilting treatment for forming the capes on the two sides; using bagged silt for riprap filling, forming a crescent bay arc line and a crescent back arc line, performing blowing and filling in a region formed between the crescent inshore bay arc line and the crescent back arc line, and forming the crescent man-made island enabling a bay to face strong wind waves; and setting a wave-blocking barrier dead ahead the crescent man-made island. In the method, the characteristics that the capes of the crescent man-made island are prominent and the bay is concave are utilized, and the principle of wave energy convergence at the capes and wave energy divergence at the bay is applied for constructing the crescent man-made island, thereby forming a crescent bay beach and realizing an ocean exploitation new mode which can realize comprehensive utilization and intensive development of fishing at reefs, swimming at the bay and harboring at the back. The method is convenient to operate and can save resources and reduce investment.

Description

technical field [0001] The invention relates to a method for constructing a silt-based artificial island, in particular to a method for constructing a crescent-shaped artificial island. Background technique [0002] The shape of artificial islands in the world is generally determined by their functions. Reclaimed artificial islands in shallow seas take wind and waves into consideration. However, no matter based on function or safety factors, the construction of artificial islands in coastal countries is making efforts to build the largest area with the least investment, because it can obtain the greatest economic benefits. Therefore, the artificial islands that people see generally have various shapes such as circles, squares, rectangles, trapezoids, ellipses, and polygons, and these artificial islands are generally widely used in ports, logistics, and real estate development. We see that the construction of all artificial islands is the most tenacious confrontation with na...
