Snow shelter for connecting bridges between tunnels

Abstract

The invention discloses snow shelter for connecting bridges between tunnels, comprising two groups of movable telescopic snow shelters which are constructed on the connecting bridges between two tunnels, have opposite positions and can be respectively expanded from the tail parts of bridge heads to the middle parts of the bridges along a traveling direction; the movable type telescopic snow shelters comprise fixed sheds installed on tunnel portals and movable sheds which can be contracted into and extended out of the inner sides or the outer sides of the fixed sheds; the fixed sheds are archsnow shelter bodies 1 constructed between the left sides and the right sides of the bridges; and the movable sheds comprise arch snow shelter bodies 2, walking wheels installed below the left sides and the right sides of the arch snow shelter bodies 2, a drive motor driving the walking wheels to move back and forth, a power supply device and a control device controlling the rotational speed and the rotation direction of the drive motor. The invention has attractive appearance, reasonable structure, low construction difficulty, convenient operation and good use effect and also can solve two main problems of low adhesion force of the bridge faces of the connecting bridges between the tunnels at the weather of rain and snow and large drop of the irradiation intensity of the inlets and the outlets of the tunnels.

Description

technical field [0001] The invention relates to a telescopic snow-proof shed, in particular to a snow-proof shed for connecting bridges between tunnels. Background technique [0002] The openings of No. 2 and No. 3 tunnels in the uplink of the Qinling Tunnel Group of the West-Han Expressway span more than 100 meters, and the two tunnel openings are connected by bridges. In the actual operation process, the bridge section between No. 2 and No. The following security issues exist: [0003] First, the impact of rain and snow on driving safety on this road section mainly includes the following factors: [0004] (1) When it snows, snowflakes obstruct the driver's sight; [0005] (2) When the weather is fine after snow, due to the strong reflection of the snow on the sunlight, the light is dazzling, which will cause glare and reduce the driver's vision, which is not good for driving safety; [0006] (3) Due to the large temperature difference between day and night in Qinling Mo...

AI Technical Summary

Problems solved by technology

[0004] (1) When it snows, snowflakes obstruct the driver's sight;

[0005] (2) When the weather is fine after snow, due to the strong reflection of the snow on the sunlight, the light is dazzling, which will cause glare and reduce the driver's vision, which is not good for driving safety;

[0006] (3) Due to the large temperature difference between day and night in Qinling Mountains, it is easy to cause repeated freezing and thawing, and the icy road brings inconvenience to safe driving;

[0007] (4) When driving on icy and snowy roads, the adhesion between the tires and the road surface decreases, and it is difficult to ensure the stability of the vehicle when the vehicle is turned and braked, and the danger increases

At present, the main methods for dealing with accumulated rain and snow include: 1. Plant more trees and rely on trees to cover part of the rain and snow; It plays a certain role, but the effect is not very good; 3. Make some road signs to remind drivers to pay attention

As for the treatment of the light intensity at the entrance and exit of the tunnel, it is generally determined according to the specific local conditions. If the lighting effect inside the tunnel is good, the light intensity outside the tunnel is not high, and the difference between the light intensity inside and outside the tunnel is not large, tree planting at the entrance of the tunnel is generally adopted. , to soften the light at the entrance and exit of the tunnel, and complete the transition of light intensity inside and outside the tunnel; If the tree is planted, the effect is not great, but the problem is that the bridge deck between Qinling No. 2 and No. 3 tunnels does not have the conditions for planting trees, so the existing methods cannot be used to deal with this section
