Embodiment Construction

[0032] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail: figure 1 It is a front view of a caisson for land reclamation in shallow seas. figure 2 It is a top view of caissons used for land reclamation in shallow seas. image 3 yes figure 1 A-A cutaway view.

[0033] In the coastal shallow sea area with a water depth of 3-5 meters, build strong sea reclamation dams that can withstand the impact of storms and tides, and form land within the sea reclamation dams, and expand the area of ​​sea reclamation in shallow sea areas to increase the effect of sea reclamation. The method of land reclamation is that the special caisson 1 for land reclamation is placed on the seabed in the shallow sea area, and is connected into sea reclamation dams.

[0034] The caisson 1 is a rectangular reinforced concrete box with the upper opening closed on the side and the bottom surface. The caisson 1 is produced on land, whi...

Abstract

The invention discloses a method for reclaiming land around sea, which aims to build a firm dam around the sea capable of resisting the impact of windstorm and tide in a coastal shallow sea area with water depth of 3-5 meters and encircles to form the land in the dam around the dam. The method comprises the following steps: placing sink boxes special for reclaiming land around sea in the shallow area at the sea bottom in the shallow area and connecting to form a dike around the sea; then floating the sink boxes on the sea and tracking the sink boxes to the preset position of the dike; filling silt into the sink boxes to sink and connect the sink boxes; adding pile fixed sink boxes inserted into the sea bottom into the sink boxes; and blowing and filling the land higher than the sea level inside the dam around the sea so as to improve the capability of the dike for resisting the impact of tidewater and the stability of the dike, wherein the sink boxes are rectangular reinforced concrete box bodies and produced by large batch flowline production on the land. The method is applicable for reclaiming land around sea on the shallow area and has high construction efficiency, low cost, good economic benefit and safe construction.

Description

technical field [0001] The present invention relates to the method field of land reclamation. Background technique [0002] There are many gentle tidal flat areas along the coast of our country. The seawater is submerged during high tide and exposed to the water surface during ebb tide. Outside the tidal flat areas, there are gentle shallow water areas with a water depth of 4-5 meters. The tidal flat areas and shallow water areas are muddy bottoms, which are difficult for people to enter It is directly developed and utilized, and is in an idle state. [0003] For example, Tianjin Binhai New Area is the focus of national development and construction. Development and construction will occupy a large amount of land. Under the condition that the basic farmland is protected by the state, basic farmland cannot be occupied. Reclaiming land from the sea is a solution to the shortage of land resources and alleviate land tension. [0004] There are many unused tidal flats and shallow...
