Problems solved by technology

However, in the centralized production process of T-beam prefabrication in this application, there are problems of steel bar processing, slow binding speed and potential safety hazards under the conditions of high cold and high altitude, and there is no reasonable testing equipment for the maintenance time and temperature of bridge components, which affects the quality of formed bridges. The quality of construction does not meet the requirements for safe use

Embodiment Construction

[0036] Below in conjunction with accompanying drawing, the present invention is described in detail.

[0037] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0038] In this example, the data used are preferred solutions, but are not intended to limit the present invention.

[0039] Such as figure 1 As shown, this embodiment provides a method for rapid prefabrication and maintenance of railway T-beams in high-cold and high-altitude areas, including the following steps:

[0040] Rapid processing steps of steel bar: Use CNC steel bar shearing equipment to straighten and cut T-beam bridge deck steel bar materials in batches. The process is picking materials → setting shearing steel bar parameters → cutting the first material → first inspecting the first material → batching Straightening and cutting → sta...

Abstract

The invention discloses a rapid prefabrication and maintenance method for railway T-beams in high-cold and high-altitude areas, and a complete set of rapid construction method for the T-beams is formed by researching a winter prefabrication technology for railway simply-supported T-beams in the high-cold and high-altitude areas. And by summarizing a concrete production technology, a pumping distribution and concrete vibrating technology, an automatic tensioning technology, an automatic grouting technology and an anchor sealing concrete heat preservation and moisture preservation maintenance technology, guarantee is provided for improving the quick construction efficiency and the product quality of the T beam in winter, and a set of complete, reasonable, reliable and efficient construction method is formed.

Description

technical field [0001] The invention discloses a rapid prefabrication and maintenance method of railway T beams in high-cold and high-altitude areas, and relates to the technical field of construction engineering. Background technique [0002] At present, with the rapid development of construction projects in my country, the construction technology is becoming more and more mature, the requirements for construction standards are getting higher and higher, and the construction cost is increasing. The railway construction project is huge, the environment in the high-cold and high-altitude area is complex, the construction conditions are harsh, and the construction is extremely difficult; further, in the railway construction, bridge engineering is an important part, and its superstructure is mostly post-tensioned. Supporting T-beams, in the prior art, in the cold environment of high-cold and high-altitude areas, the temperature of the concrete leaving the machine is difficult to ...
