Stepped multilevel sea reclamation method and sea reclamation dams provided with downward insertion caissons

Abstract

The invention discloses a stepped multilevel sea reclamation method and sea reclamation dams provided with downward insertion caissons. Stepped multilevel sea reclamation dam structures are adopted, sea reclamation processes of building and filling sand are carried out in a graded manner from bottom to top in sequence, the sea reclamation dams in different levels are isolated, are parallel to each other and are gradually ascended from the sea side to the land side so as to be stepped; the sea reclamation dam of each level is formed by connecting a plurality of sea reclamation dam unit components, which are provided with the downward insertion caissons and are used for stepped multilevel sea reclamation, the transverse soil pressure of the sea reclamation dams is decomposed to multiple levels through the stepped multilevel sea reclamation dam structures, the soil pressure of each level is small, so that the security coefficient of the sea reclamation dams is improved, and the impact of waves can be reduced through the multilevel steps, thus the section size of the sea reclamation dams can be reduced, the material utilization amount is low, the investment and the construction difficulty are reduced, the construction efficiency is high, the cost is reduced, the construction period is short, and the effect is better, particularly in a deep sea reclamation water area.

Description

technical field [0001] The invention relates to the field of port hydraulic structures. Background technique [0002] With the development of the economy, a large amount of land is needed for production and life, and the land is getting more and more tense. Asking for land from the sea is one of the solutions, and land reclamation is the way for humans to ask for land from the sea. When reclamation and land reclamation, it is first necessary to build breakwaters or reclamation enclosures around the reclamation sea area to isolate the reclamation sea area from the sea, and then use large dredgers to dredge the sand in the far sea, and remove the excavated sand Blow fill into the reclamation area to make the reclamation area land. There is a height difference between the mud surface on the sea side and the land side of the land reclamation enclosure, and the height difference of the mud surface forms a lateral earth pressure. The effect of the earth pressure will make the rec...

Problems solved by technology

Due to the large amount of reclamation works and the long construction time, extreme weather and sea conditions may be encountered during the construction process. Extreme weather and sea conditions form storm surges. The land encirclement formed a huge impact, and even caused the failure of land reclamation

In order to prevent the above situation from happening, when designing breakwaters or reclamation enclosures, it is necessary to increase the section size of breakwaters or reclamation enclosures to increase the strength and insurance factor, increase the amount of materials, and increase the difficulty and engineering volume of construction. , so the cost rises and the investment increases, especially in deeper waters, the cost will increase exponentially
