Embodiment 1

[0040] In this embodiment, a complete set of construction method for arch and culvert with mobile hydraulic trolley, including establishing a track, using a side wall formwork trolley to construct the side wall along the track, and using a vault formwork trolley to follow the track on the foundation of the side wall For the construction of the vault, the side walls are connected to the vault to form an arch culvert.

[0041] Taking the length direction of the track as the benchmark is conducive to ensuring the straightness of the side walls, vaults, and the overall arch culvert formed by the side walls and vaults, so that the accuracy of the completed arch culvert is high. Prioritize the construction of the side walls, which can provide a foundation for the construction of the vault and reduce the positioning work during the construction of the vault. And the side wall has no closed structure, which can avoid interference between the construction structure and the construction...

Embodiment 2

[0043] In this embodiment, a mobile hydraulic trolley arch culvert construction method includes the following steps:

[0044] Step S1: Prepare the foundation pit used as the construction site, so that the foundation pit meets the construction requirements.

[0045]Step S2: Construction of culvert foundation.

[0046] Step S3: Assemble the side wall formwork trolley, including assembling the side wall running system on the culvert foundation, assembling the side wall gantry system on the side wall running system, and assembling the side wall formwork system on the side wall formwork trolley.

[0047] Such as figure 1 , figure 2 , image 3 As shown, the running system includes two side wall rails 14 arranged in parallel.

[0048] The side wall door frame system includes two side wall door frame longitudinal systems respectively slidingly arranged on the two side wall rails 14 and a side wall door frame transverse system for connecting the two side wall door frame longitudin...

Embodiment 3

[0063] Such as figure 1 As shown, on the basis of the above embodiments, in this embodiment, the side wall formwork system includes side wall outer formwork 9, side wall A, which are symmetrically distributed on the symmetrical plane of side wall rail 14 and arranged sequentially from outside to inside. The inner mold 11 and the side wall B inner mold 13 located between the two side wall gantry longitudinal beams 1 . Such as Figure 4 As shown, there are side wall A end molds 18 located at both ends of the side wall A inner mold 11 between the side wall outer mold 9 and the side wall A inner mold 11 . The side wall A pouring space is formed around the side wall outer form 9 , the side wall A inner form 11 and the side wall A end form 18 . Such as Figure 5 As shown, the side wall B end mold 19 located at both ends of the side wall B inner mold 13 is arranged between the side wall B inner mold 13 and the side wall B inner mold 13, and the side wall B inner mold 13 is connect...

Abstract

The invention discloses a complete set of construction method for an arch culvert with a mobile hydraulic trolley, which includes establishing a track, using a side wall formwork trolley to construct the side wall along the track, and using a vault formwork trolley to construct on the foundation of the side wall along the track Vault, the side wall is connected with the vault to form an arch culvert. The beneficial effects of the present invention are: the present invention can ensure the straightness of the side wall, the vault and the overall arch formed by the side wall and the vault, so that the accuracy of the arch culvert after construction is high, and the construction of the side wall is given priority, which can be a perfect arch for the vault. The construction provides a foundation to reduce the positioning work during the construction of the vault, and the side wall has no closed structure, which can avoid interference between the construction structure and the construction device, so that it is not necessary to repeatedly disassemble and assemble the mold or formwork trolley, which is beneficial Improve construction efficiency and shorten construction period.

Description

technical field [0001] The invention relates to the technical field of arch and culvert construction, in particular to a construction method for a complete set of arch and culvert with a mobile hydraulic trolley. Background technique [0002] As an important part of road bridges, culverts have different structural forms such as slab culverts, round pipe culverts, box culverts and arch culverts, all of which have their own scope of application. In recent years, with the construction and development of mountainous roads and a large number of railways, the phenomenon of deep excavation and high filling has inevitably appeared for the requirements of road alignment, and high filling embankments have gradually increased. The reinforced concrete arch culvert converts the upper filling load and live load into the axial force of the arch, which greatly exerts the mechanical properties of the material. It is a structural form with reasonable stress and high economic benefits. Due to ...
