Buoyancy tank type deepwater pile group bridge abutment construction platform and construction method thereof

Abstract

The invention provides a buoyancy tank type deepwater pile group bridge abutment construction platform and a construction method of the construction platform. The buoyancy tank type deepwater pile group bridge abutment construction platform comprises a buoyancy tank type construction platform body prefabricated according to the size of a bridge abutment and the size of pile positions, and a working platform is erected on the upper portion of the buoyancy tank type construction platform body. The buoyancy tank type construction platform body is positioned through an anchorage device. Pile holes for pile driving are preformed in the bottom face of the buoyancy tank type construction platform body, and casing pipes for pile body steel tubes to penetrate through are arranged on the pile holes and connected with the edges of the pile holes in a sealing mode. Rubber water sealing rings capable of being inflated with high pressure gas or being infused with high pressure water are arranged at the joints of the outer walls of the pile body steel tubes and the bottom portions of the corresponding pile holes. The invention further provides the construction method of the buoyancy tank type deepwater pile group bridge abutment construction platform. The buoyancy tank type deepwater pile group bridge abutment construction platform is not only used as a bridge abutment die, but also used as a platform for pile foundation operation at sea, and therefore construction difficulty is lowered, the job progress is quickened, a large number of artificial materials are saved, equipment input is reduced, and full-water-surface operation which saves time, guarantees the quality, and is efficient and safe is achieved for the buoyancy tank type construction platform.

Description

technical field [0001] The invention relates to the technical field of deep-water pile foundation abutment construction, in particular to a buoyant box-type deep-water group pile abutment construction platform for full-water operation and a construction method thereof. Background technique [0002] With the rapid development of bridge construction in our country, new breakthroughs have been made in bridge construction technology. Some large sea-crossing and river-crossing bridges have high design standards and technical content, and complex technical and construction conditions, representing the highest level of bridge construction today. The key and difficult point of bridge construction lies in the construction of deep water pile foundation and bridge abutment. [0003] The general process of the existing deep-water pile group abutment construction process is: inserting special steel pipe piles → setting up the pile foundation construction platform → sinking the steel cas...

AI Technical Summary

Problems solved by technology

[0004] This construction technique is not only difficult to construct and slow in project progress, but also causes a lot of waste of artificial materials and a large investment in equipment; the installation of steel hanging boxes is difficult, and it is easy to cause safety accidents
