Jetty type wharf with caisson structure, and construction method thereof

Abstract

The invention discloses a jetty type wharf with a caisson structure. The jetty type wharf with the caisson structure comprises a wharf body, wherein the wharf body comprises a plurality of caissons; aclearance is left between each two adjacent caissons so as to be used as a passing passageway; a wharf surface layer is arranged at a position, corresponding to each caisson, on the top part of eachcaisson; a connecting part with a deformable structure is arranged between each two adjacent wharf surface layers; and the each adjacent wharf surface layers are connected through the connecting partso as to form an overall wharf surface layer. The invention further provides a construction method of the jetty type wharf with the caisson structure. The invention aims to provide the jetty type wharf applying the gravity type caisson structure and the construction method thereof. The influences of wave reflection and refraction in front of an upright wall type structure wall can be effectively reduced, a favorable berthing or mooring condition is provided for ships, meanwhile, the construction cost can be saved, and the construction period is shortened.

Description

technical field [0001] The invention relates to the technical field of port and wharf engineering, in particular to a jetty wharf using a gravity caisson structure and a construction method thereof. Background technique [0002] In recent years, with the rapid development of my country's economy, major coastal cities have made full use of their regional advantages to vigorously develop port construction and maritime transportation. With the vigorous development of the entire water transportation industry, there are fewer and fewer available natural coastline resources. , as a special natural resource and land resource, the coastline is of great significance. Therefore, improving the utilization efficiency of the port shoreline resources is not only the need of scientific development, but also has very important practical significance for realizing the sustainable development of the port. [0003] In view of the increasingly tense natural shoreline resources, effective ways t...

Problems solved by technology

[0007] 2. Offshore terminal

[0008] Offshore piers generally refer to deep-water piers far from the coastline, and most of them do not have wave protection facilities. Although offshore piers are not restricted by the existing shoreline, their applicability is poor

First of all, the natural conditions such as wind, waves, and currents in the water area where the offshore terminal is located are relatively complex, which requires high stability and safety of the terminal structure and requires a large investment; secondly, its applicable ship types are limited, and are generally suitable for anti-wave Ships with strong stability or low requirements for berth stability; thirdly, they cannot be directly connected to the land area, do not have the water and land transportation environment, and cannot be transferred

These all limit the construction and development of offshore terminals

[0009] 3. Jetty type wharf

In the past, the gravity-type caisson structure was mostly used in the full-height wharf along the bank, and most of them used continuous caisson arrangement, which made the project cost relatively high and the construction period relatively long; In this arrangement, the reflection and refraction of waves in the harbor are more complex, which is unfavorable to the stress of the hydraulic structure and the stability of the waters in the harbor.
