Embodiment 1

[0036] Embodiment 1 is cross-railway protective shed:

[0037] Such as figure 1 Shown is the layout of the bridge, existing railway lines, existing highway lines, and protective sheds. In order to ensure the normal and safe operation of the railway during the construction period, protective sheds must be erected on both sides of the road beams 30 meters away from the major and minor mileages of the railway. The protective shed adopts one span across the existing railway line, obliquely intersects with the existing highway line, the angle of intersection is 45°, and the span is 13.5m.

[0038] In order to meet the horizontal and vertical stability of the protective shed, the number of supporting columns on one side of the railway is 6, the spacing is 6M, and the height is 10.66m.

[0039] In order to meet the electrical insulation of the protective shed, the hoisting units that make up the roof include iron sheets, wooden boards, insulating boards, and beams 22 from top to bot...

Embodiment 2

[0085] Embodiment 2 is cross-highway protective shed:

[0086] Figure 4 It is the layout diagram of the bridge, the existing road, and the protective shed. In order to ensure the normal and safe operation of the road during the construction period, a protective shed must be set up under the bridge. Set the width to 12m, and set the width to 16m on the right. In order to ensure the clearance requirements for highway driving, the minimum height from the protective shed to the road surface is 5m, and the protection scheme is as follows:

[0087] The number of support units is 3, and the outer support units are arranged on both sides of the road. In order to meet the horizontal and vertical stability of the shelter, the number of support columns for each support unit is 5, with a height of 3.7m and a spacing of 6m.

[0088] In order to meet the strength requirements of the protective shed, the longitudinal beams are made of 20b double-channel steel, the beams are 18b double-cha...

Abstract

The invention provides an existing line protective shed which mainly comprises three parts, namely a foundation, vertical columns and a ceiling, wherein the foundation and the vertical columns, and the vertical columns and the ceiling are all connected through threaded fixing devices. The protective shed has a simple structure and facilitates the mounting and the dismounting, and the ceiling is composed of a plurality of hoisting units. By adopting the structure provided by the invention, the construction speed is accelerated, and the wind resisting and seismic effect is good; and a plurality of ventilation holes are formed in the ceiling, so as to realize ventilation and prevent object from falling within the line range.

Description

technical field [0001] The invention relates to a protective shed used in the building construction process, in particular to a protective shed used for protecting the safe operation of existing lines. Background technique [0002] With the development of my country's traffic construction, there are more and more constructions using protective sheds for safety protection when crossing existing railways or highways. The problems that need to be solved for the protective sheds on existing high-speed lines are: [0003] 1. The support strength and stability of the scaffold structure must meet the wind force caused by the moving train passing by; [0004] 2. It is inconvenient to install and dismantle the protective scaffolding, and there are safety problems; [0005] 3. Prevent any objects from falling into the line range during operation. [0006] If these problems are not resolved, construction safety and high-speed railway driving safety cannot be guaranteed. Contents of...
