Pile bearing type half-sphere breakwater structure and construction method

Abstract

The invention discloses a pile bearing type half-sphere breakwater structure and a construction method, and relates to the technical field of water conservancy projects. According to the technical scheme, the structure comprises a half-sphere structure, a foundation pile, a broken stone pad layer and bottom protection stone; the half-sphere structure comprises a base, multiple fixing devices are arranged on the base, each fixing device comprises a mounting hole and a first fixing mechanism, each first fixing mechanism comprises an annular block, multiple elastic plates and a pushing assembly,each pushing assembly comprises an annular plate, a transition pipe communicating with the end, close to the mounting hole, of the annular plate and a pushing pipe communicating with the end, away from the annular plate, of the transition pipe, the annular plates are arranged in a manner of protruding out of the bottoms of the mounting holes, first sinking holes used for placing the annular platesare preset in the bottom of the base, the pushing pipes are arranged in the mounting holes in a slippage manner in the axial direction of the mounting holes, and a driving assembly used for driving the annular plates to move in the vertical direction is arranged on the base. The fixing devices are arranged, the half-sphere structure can be conveniently dismounted and mounted, and the half-spherestructure can be conveniently replaced.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a pile-supported semicircular breakwater structure and a construction method. Background technique [0002] Breakwaters are water structures built to block the impact of waves, protect the harbor basin, maintain a stable water surface to protect the port from bad weather, and allow ships to berth and operate safely. The breakwater can also play a role in preventing the siltation of the harbor basin and the erosion of the shoreline by waves. It is an important part of artificially sheltered coastal ports. It is generally stipulated that the allowable wave height in the port is between 0.5 and 1.0 meters, which is determined according to the needs of different parts of the water area, different types of ships and tonnage. The breakwater is often composed of one or two jetties connected to the shore or unconnected island dikes, or composed of both jetties and...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned semicircular structure may be damaged under the impact of seawater for a long time, and the semicircular structure is fixedly connected with the foundation pile structure through the grouting material, which makes it inconvenient to disassemble the semicircular structure and thus inconvenient to replace the semicircular structure
