Embodiment Construction

[0032] The structure of the present invention will be explained in detail below in conjunction with the accompanying drawings. The specific embodiment is a railway overhead fixing device, such as figure 2 It is a schematic plan view of the line reinforcement of the present invention, including a longitudinal beam 1 and a corbel 2, and the longitudinal beam is connected by a plurality of construction beams 10 through connecting plates and other strengths. Such as Figure 4-6 It is a structural schematic diagram of the convenient beam of the present invention; the connecting plate is composed of a web 13, an outer cover plate 11 and an inner cover plate 12, and is fixedly covered between the convenient beams, such as Figure 7 It is a schematic diagram of the connection of the utility beams into longitudinal beams in the present invention, and the utility beams are fixedly connected as a whole by bolts. The corbel beam passes through the track 7 and is parallel to the concrete...

Abstract

The invention discloses a railway elevating and fixing device and a railway bridge and culvert construction method adopting the railway elevating and fixing device. The railway elevating and fixing device comprises longitudinal beams and a sleeper beam, the sleeper beam penetrates through a track downwards and is parallel to a concrete sleeper, the top parts at the two ends of the sleeper beam are respectively and fixedly connected with one longitudinal beam perpendicular to the sleeper beam, and a support point pile used for supporting a beam body is fixed under the longitudinal beam. The railway elevating and fixing device and the railway bridge and culvert construction method adopting the railway elevating and fixing device solve the problem that the fixing effect of the traditional railway bridge and culvert construction method can not meet the requirements for the railway speed, and the elevation span can not meet the requirements for large span bridge and culvert passing.

Description

technical field [0001] The invention belongs to the field of road and bridge engineering, and in particular relates to a railway overhead fixing device and a method for adding railway bridges and culverts using the device. Background technique [0002] At present, the national railway network has been basically formed, and the level of the road network is getting higher and higher. With the development of the economy, urban roads, highways, and shipping traffic are developing rapidly. It is very common for roads and rivers to cross railways, and the crossing span is also increasing. The bigger the railway interchange has developed from the original single-hole small bridge to the porous large frame. The original D-type construction convenience beam construction method and the suspension rail cross-lifting beam construction method are currently being used for large frame construction and more and more current line conditions. There are many deficiencies, mainly in the follow...
