Wharf caisson water taking device and construction method

Abstract

The invention provides a wharf caisson water taking device and a construction method. A reinforcing bar caisson comprises a caisson compartment which is formed by a front wall, a rear wall, side walls, a longitudinal separating wall and a transverse separating wall and is characterized in that a flow guiding wall is arranged in the reinforcing bar caisson, a water inlet hole is formed in the frontwall, energy dissipation holes are formed in the longitudinal separating wall and the transverse separating wall, a hole is formed in the rear wall, the hole is connected with a large water taking pipe, the large water taking pipe is provided with a water sealing component, and concrete is poured on part of the bottom and top of the caisson compartment to form a dam body of a gravity wharf, the lower portion of the dam body is a block stone bed on the sea floor, the upper portion is a reinforcing bar concrete breast wall, the rear side is a block stone prism, and the top is a surface layer structure. According to the device, a water taking port is combined with a large wharf structure, a sea area is not needed to be selected separately to form the water taking hole, the occupation on thesea area is reduced, a large amount of construction time is saved, and a large amount of engineering cost is saved. The caisson water taking structure is reasonably arranged to protect the safety of facilities in a harbor basin.

Description

technical field [0001] The invention belongs to the technical field of port, coastal engineering and water intake, and mainly relates to a large-scale reinforced concrete prefabricated heavy part structure of port and coastal engineering, in particular to a wharf caisson water intake device and a construction method. Background technique [0002] Wharf structures mainly include gravity type, high pile, sheet pile and other types. Among them, the gravity type wharf has the advantages of good durability, strong earthquake resistance, strong adaptability to ground loads, and easy transformation, and is widely used in some areas with good geological conditions. Due to its size, large weight, good integrity, less water installation and convenient floating installation, caissons are often used in deep water wharf projects. [0003] The water intake in offshore engineering is often set in deep coastal waters, where the water temperature and water quality meet the requirements, and...

Problems solved by technology

Especially when the demand for water in the rear is large and the size of the berthing ship in the front is large, how to install and construct is a big difficulty in combining the two.
