Embodiment Construction

[0016] In order to enable those skilled in the technical field to which the application belongs to understand the application more clearly, the technical solutions of the application will be described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0017] Such as figure 1 As shown, the bridge pier structure includes: cylinder 1, cylinder top cover plate 2, conical platform column 3, upper cap plate 4, bridge deck 5 (in order to explain the present invention more intuitively, introduce bridge deck 5 here), cross-shaped partition wall6.

[0018] The cylinder 1 is hollow, the diameter of the outer ring ranges from 6m to 20m, and the height ranges from 3m to 15m.

[0019] Such as figure 2 As shown, the cylinder 1 is provided with a cross-shaped partition wall 6 , and the height of the cross-shaped partition wall 6 is less than or equal to the height of the cylinder 1 . The upper part of the cylinder 1 is provided with a cylinder to...

Abstract

The invention discloses a bridge pier structure. A bridge pier foundation structure is a cylinder and a cross partition wall is arranged in the bridge pier foundation structure, and thus, the design has a good stress effect and materials are reduced. A cone frustum pillar has a slope face and is integrally in rigid connection, and thus, when the water surface is iced, floating ice has a small ice acting effect on the bridge pier structure, so that the ice resistance of the bridge pier structure is strong. Moreover, an upper pile cap is arranged at the top of the bridge pier, so that the span and the thickness of a bridge panel can be reduced and engineering cost can be reduced.

Description

technical field [0001] The invention relates to the fields of offshore oil and gas engineering and the fields of port and coastal engineering, in particular to a bridge pier structure. Background technique [0002] It is an economical, fast and effective way to develop offshore oil and gas resources by adopting the development model of "offshore oil and land production". Exploitation of subsea oil and gas resources. The road into the sea includes trestle bridges and physical roads. The trestle has the characteristics of flow through and has little impact on the marine environment. It is a structure that must be adopted for long-distance access to the sea. [0003] In offshore engineering, commonly used trestle structures include gravity pier foundation trestle structure, pile foundation trestle structure, and barrel foundation trestle structure. Among them, the gravity pier trestle structure has good durability and high bearing capacity, but the traditional gravity pier t...
