A prefabricated frame receiving and sliding device on a slope-changing slideway and its application method

Abstract

The invention discloses a device which receives a prefabricated frame and slides on a variable slope slideway and an application method thereof. From broken section terminal of an upper slope varying point, two slideway steel plates (1) are laid at the two sides of the variable slope slideway; and one receiving steel plate (2) is movably arranged on each slideway steel plate (1). When the prefabricated frame jacks and passes the upper slope varying point, the slideway steel plate for a first section is laid, butter is smeared on the slideway steel plate, and one receiving steel plate is arranged on each of left and right steel plate slideways; the prefabricated frame jacks continuously until the front end of the prefabricated frame falls onto the receiving steel plates; the prefabricated frame jacks continuously, the receiving steel plates displace relatively on the slideway steel plates until the prefabricated frame slides to the front end of the slideway steel plate for the first section along with the receiving steel plates, and meanwhile, the slideway steel plate for a second section is laid; and the prefabricated frame jacks continuously until the prefabricated frame is jacked in place according to a designed plane position. The device disclosed by the invention can guarantee that the prefabricated frame rapidly and accurately carries out jacking construction with the lowest jacking force after turning over and entering a slope ramp, and no damage to the slideway is caused.

Description

technical field [0001] The invention relates to a frame receiving and sliding device, in particular to a frame receiving and sliding device on a slope-changing slideway. The invention also relates to a method of using the frame receiving and sliding device on a gradient slide. Background technique [0002] At present, there is a situation that after the prefabricated frame is prefabricated outside the line, it is found that the actual elevation of the upstream drainage culvert does not match the design—the elevation of the upstream flow surface is lower than the design flow elevation of the newly built railway-related culvert, resulting in the frame culvert being built according to the design. Unable to drain. In order to solve the problem of culvert drainage, it is necessary to lower the design elevation of the culvert in the railway section. Since the prefabricated frame has been prefabricated according to the original design elevation, the jacking slideway of the prefab...

Problems solved by technology

That is, during the jacking process of the prefabricated frame, the slope of the jacking slideway is reduced, and the jacking construction of the prefabricated frame is carried out on the slope-changing slideway. In the simply supported state and during operation on the ramp, due to the surface friction of the concrete slideway, the jacking force is consumed too much, and the surface of the slideway is easily damaged, and the jacking direction is difficult to control, and the jacking speed is slow. How to ensure the prefabricated After the frame is overturned into the ramp, the rapid and accurate jacking construction will be carried out with the least jacking force without causing damage to the slideway, which requires solving the problem of frame reception after the prefabricated frame is overturned
