Slope-type caisson breakwater

Abstract

The invention discloses a slope type caisson breakwater composed of a plurality of slope type caisson bodies arranged lengthways. The top portion of each slope-type caisson body is a caisson body levee crown slope surface rising from the seaside to the port side of the breakwater, the inclination of each caisson body levee crown slope surface is between 1:3 to 1:1, and each caisson body levee crown slope levee crown inclined surface of a caisson body surface is one to 4 times as high as waves. The slopes of slope-type caissons enable waves to break on the slope surfaces, most of wave energy is absorbed and dissipated during moving on slope surface, wave reflection is little, and the breakwater has high stability and good protecting effects. As a breakwater body is made of the slope type reinforced concrete caissons, building materials are saved, construction efficiency is high, manufacturing cost is low, investment is saved and construction period is shortened.

Description

technical field [0001] The invention relates to the field of port hydraulic structures. Background technique [0002] The breakwater is an important hydraulic structure in the port. It is used to prevent waves from invading the port area, to ensure a stable water area in the port, to facilitate the berthing and mooring of ships, to carry out cargo loading and unloading operations and passengers on and off smoothly. It may also have sand and flow prevention. , anti-icing, diversion or the inner side doubles as the function of the dock. With the development of the world economy and the growth of trade, in order to reduce the cost of water transportation and increase the size of ships, good harbors have been developed, and new ports have to be developed in sea areas with harsh environments. Building breakwaters in sea areas with deep water, large waves, and complex geology is a must. inevitable trend. [0003] Breakwaters can be divided into slope type, vertical type and spec...

AI Technical Summary

Problems solved by technology

The concrete caisson is manufactured on land as a whole, which is convenient for construction and low in manufacturing cost. The energy dissipation effect of the vertical box-shaped breakwater is poor. In the construction process, large-scale special construction machinery is generally required, and the construction is complicated. If the foundation is weak, it needs to be reinforced and the cost is high.

Once the vertical breakwater is damaged, the consequences will be serious and it will be difficult to repair

[0006] The existing breakwater structure has high cost and large investment, which can no longer meet the needs of economic development and construction

Especially it is more difficult to build breakwaters in shallow sea areas with soft soil foundations. The treatment of soft soil foundations requires labor and materials, and the cost is extremely high.
