Embodiment Construction

[0034] Ninghe Intercity Rail Transit Line S3 is a fast rail transit line from Nanjing City, Jiangsu Province to Hexian County, Anhui Province, and is part of the rail transit network of Nanjing metropolitan area. The construction scope of the NH-TA09 standard is 1 station and 1 section, of which the total length of the section from Ecological Science and Technology Park Station to Zhushi Road Station is 3803.52m, and the total length of the bridge is 6290m. The 36-span simply-supported box girder at the starting point of the left and right lines of the interval is constructed using the Bailey bracket method. The length of the simply-supported beam is 30m, and the weight of a single-piece cast-in-place box girder is 290t.

[0035] The following is an example of a Bailey stent removal using a slip-and-slide removal device:

Abstract

The invention relates to a sliding-type Bailey beam dismantling device and a dismantling method thereof. The device is characterized by being composed of two sets of jacks, two sets of special lift carrying poles, a plurality of sliding wheels and a manual crane; the two sides of the bottom of a Bailey beam main body are each provided with one set of the jacks, the two sets of special lift carrying poles are erected between the jacks on the two sides, each set of the special lift carrying poles are fixed with a Bailey beam in a supporting mode, the sliding wheels are installed at the bottom of the Bailey beam main body, the side of the Bailey beam main body is connected with the manual crane, and the Bailey beam is transversely moved through the manual crane. According to the sliding-type Bailey beam dismantling device and the dismantling method thereof, the sliding wheel moving principle is utilized, the friction force is reduced by installing the sliding wheels on the Bailey beam, the Bailey beam is moved to the outer side through the manual crane, the on-site operation difficulty is reduced, and the safety risk is reduced.

Description

[0001] [technical field] [0002] The invention belongs to the science of engineering technology, and in particular relates to a device and a method for removing Bailey beams by sliding. [0003] [Background technique] [0004] Bailey beams are mostly used in engineering construction. They are truss beams assembled with Bailey frames. Flower windows are mostly used as connecting components between Bailey frames and fixed with bolts. Because of their rapid erection and strong mobility, they are mostly used in rivers, Simple bridges are erected on cliffs, which are mostly used in engineering construction, such as gantry cranes, construction platforms, engineering access bridges, etc. Bailey beam erection is convenient and quick, and it is an important support system in the construction of many cast-in-place continuous box girders across highways and rivers. In the construction of hanging baskets and highways crossing rivers, it can also be used as a construction access road, whi...
