Unloading type t-type sheet pile breakwater enclosure

Abstract

The invention relates to an unloading T-type sheet pile breakwater cofferdam. The cofferdam is formed by an upper wave-proof structure and a lower retaining structure. The wave-proof structure comprises an arc wave-proof wall and a fence-type wave-proof wall. The retaining structure is composed of an unloading plate, T-type sheet piles, covered square piles and cable-stayed anchor piles; the unloading plate is composed of an unloading bottom plate, an unloading vertical plate and an unloading top plate, the unloading vertical plate is arranged on the unloading bottom plate, and the unloading top plate is arranged on the unloading vertical plate; the set of T-type sheet piles are arranged in the front of the bottom of the unloading bottom plate, the set of unloading vertical plates are arranged on the rear portion of the unloading bottom plate, and the set of cable-stayed anchor piles are arranged at the bottom of the unloading bottom plate. The arc wave-proof wall of the wave-proof structure is located on the unloading top plate, the fence-type wave-proof wall is located on the front portion between the unloading bottom plate and the unloading top plate, and the unloading bottom plate extends toward the rear portion to form a road supporting plate. The functions of a cofferdam and a sea surrounding external wall are achieved, and the cofferdam can bear roads constructed on a soft foundation and is convenient to construct, low in construction cost and suitable for deepwater conditions.

Description

technical field [0001] The invention relates to a port and coastal engineering building structure, in particular to an unloading type T-shaped sheet pile breakwater enclosure. Background technique [0002] With the economic development of coastal areas, the shortage of land resources has become increasingly prominent, which has become a key factor restricting the further development of the region. In order to meet the needs of economic development for land, land reclamation projects are increasingly being used in engineering practice. Taking Tianjin Port as an example, as of 2015, the land reclamation area has exceeded 100 square kilometers, and the area of ​​the second island in the eastern Xinjiang of Tianjin Port that is further planned and constructed has an area of ​​more than 40 square kilometers. [0003] The land reclamation project at the present stage presents the following characteristics: 1. Economic development has an urgent need for land, which requires a fast...

AI Technical Summary

Problems solved by technology

The traditional enclosure structure is mainly a gravity-type slope embankment, but its material consumption is roughly proportional to the square of the water depth, and the cost is high when the water depth is large

In recent years, new types of breakwaters and enclosure structures such as semi-circular light gravity breakwaters, box-shaped foundation breakwaters, and submerged large cylinder breakwaters suitable for soft soil foundations have also been developed, but all of them have limited use conditions and some undeveloped structures. solved problem

The semi-circular light gravity breakwater is expensive when the water depth is large, and is not suitable for deep water conditions; the box-type foundation breakwater has a complex structure and difficult construction; the submerged large cylinder breakwater, under the action of a strong typhoon wave The overturning failure occurred under the condition, which made its safety and reliability in engineering applications questioned.
