Embodiment Construction

[0025] According to attached figure 1 It can be seen that this application specifically relates to a casting-in-situ construction method for the flange plate of the sound barrier beam of the mobile formwork vehicle. Pouring construction. The specific construction process is as follows: construction preparation → formwork truck assembly → walk in place, check equipment → formwork falls in place → install fine-rolled rebar → prepare steel bars, place embedded parts → install hanging formwork and formwork → concrete pouring → formwork removal → Raise the bottom mold and transition. This method is based on the practical experience of engineering construction.

[0026] The principle of the construction method in this application: the construction conditions can be divided into single-line or double-line, with or without track laying, and catenary on one or both sides. Mobile formwork trucks for construction.

[0027] Its specific construction process is as follows:

Abstract

The invention discloses a cast-in-situ construction method of beam flange plates of acoustic barriers through movable mold base vehicles, and relates to the technical field of bridge construction. The cast-in-situ construction method comprises the specific construction technological processes of preparing for construction; assembling the mold base vehicles; enabling the mold base vehicles to run to proper positions, and inspecting equipment; enabling templates to drop off to proper positions; enabling finish rolling screw-thread steel to be mounted; binding reinforcing bars, and placing embedded parts; mounting hanging molds and explorators; casting concrete; disassembling molds; lifting bottom molds and shifting to another site. According to the construction method disclosed by the invention, the problem that the cast-in-situ construction of flange plates of a high pier is difficult is solved; besides, the construction method is safe and reliable, and is simple and convenient to apply.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a method for cast-in-situ construction of a sound barrier beam flange plate by using a mobile formwork vehicle under the working conditions of single and double lines and with or without tracks. Background technique [0002] With the rapid development of domestic railway infrastructure construction, a large number of railways have emerged near residential areas. In order to reduce traffic noise and reduce noise interference to the surrounding environment, sound barriers need to be installed outside the bridge. For this reason, the Economic Planning Research Institute of the Ministry of Railways released the "200 km per hour Passenger and Freight Collinear Railway Prefabricated Post-tensioning Simply Supported T-beam (Setting up Sound Barrier)" drawing number: Tongqiao (2012) 2209 general reference map, and "Speed ​​per hour" at the end of 2012 Prefabricated post-tensi...
