Embodiment Construction

[0026] A method for constructing highway and railway swivel bridges by using a turntable spherical joint, comprising the following steps:

[0027] 1. Turntable spherical hinge processing:

[0028] The spherical joint is entrusted to 725 Institute to design and produce, with a bearing capacity of 5,500t. It is divided into three parts: the upper spherical joint, the lower spherical joint and the center pin shaft. 0.293m, the diameter of the central pin shaft is 300mm. The ball hinge is composed of upper and lower steel ball panels. The upper panel is convex and connected to the upper traction disc through the truncated cone. The upper disc is located on the traction disc. The lower panel is concave and embedded in the top surface of the lower disc. The upper and lower panels are all spherical surfaces pressed by 30mm thick steel plates, and ribs are set on the back to prevent deformation during processing and transportation, and facilitate the positioning of the ball joint and...

Abstract

The invention relates to a method for constructing a bridge, in particular to the method for constructing a road swivel bridge and a railway swivel bridge by using a turnplate spherical hinge, which aims to solve the problems of the complex process, inconvenient construction, high requirements on construction sites, and the like of the conventional swivel bridge construction. The method specifically comprises the following steps of: machining the turnplate spherical hinge; constructing a lower pile cap and mounting a lower spherical hinge and an endless track, wherein the concrete of the lower pile cap is poured in three stages; constructing an upper pile cap and mounting an upper spherical hinge and a support steel cylinder; and after the upper pile cap and the lower pile cap are swiveled in place under the action of the turnplate spherical hinge, pouring rear sealed concrete between the upper pile cap and the lower pile cap. The method has the advantages of the capacity of changing overhead barrier operation into operation on the coast or near the ground, safe and reliable construction, simple and convenient operation, fast implementation and construction cost reduction, is suitable for both straight bridges and curved bridges, and compared with the conventional construction methods, also has the advantages of shortening construction period, saving a part of big constructionmachinery and labor force and greatly saving construction cost.

Description

technical field [0001] The invention relates to a bridge construction method, in particular to a method for constructing highway and railway swivel bridges by using a turntable spherical joint. Background technique [0002] At present, most of the highway and railway swivel bridges adopt traditional construction methods, such as the full house support method and the hanging basket method directly in the direction of the line, and the following problems exist in actual construction: [0003] (1) There are many machines and equipment required for construction, the process is complicated, and the operation is dangerous; [0004] (2) Inconvenient construction and large interference; [0005] (3) It is generally impossible to overcome the difficulties of erecting large-span structures on high mountains and canyons, deep water, fast-flowing or often navigable rivers, especially for building overpasses and railway flyovers in busy cities, the disadvantages are more obvious, becaus...
