Embodiment Construction

[0011] Such as figure 1 Shown, the method for antifreezing of road tunnels of water conservancy projects in cold regions of the present invention, comprises the following steps and carries out:

[0012] The first step is to build a door slot 2 at the entrance of the road tunnel 1, and then install a hard fast lifting door 3 in the door slot;

[0013] Second step, in the road tunnel 1, the distance door slot 2 fifty meters away from the sensor device 4 and the sensor device 5 are set, when the car passes through the sensor device 4, 5, the hard fast lifting door 3 rises;

[0014] The third step is to set manual buttons 6.1 and 6.2 on the door slot 2 for controlling the lifting of the hard fast lifting door 3 .

[0015] When the automobile enters the road tunnel 1 before fifty meters, the induction device 5 is sensed and the induction signal is transmitted to the access control controller of the hard fast lifting door 3, and the access control controller drives the hard fast li...

Abstract

The invention discloses an anti-freezing method for a cold region water conservancy project road tunnel. The method comprises: 1, building a gate slot on a road tunnel portal, and then mounting a hardrapid lifting gate in the gate slot; 2, arranging induction devices on positions in an out of the road tunnel, the distance between the position and the gate slot being a set distance, when a vehiclepasses through the induction device, the hard rapid lifting gate lifting up; 3, arranging manual buttons used to control the hard rapid lifting gate to lift in and out of the gate slot. The method isdesigned for road tunnels used in cold region water conservancy projects. When no vehicle travels, the tunnel portal is sealed by the hard rapid lifting gate, and temperature in the tunnel is greatlyincreased under the action of ground temperature, and temperature in the tunnel is closed to ground temperature, so as to ensure the back of road tunnel lining and drainage ditches not to freeze, andachieve an objective of road tunnel anti-freezing. Therefore, for road tunnels used in cold region water conservancy projects, according to the method, heat insulation boards and a deeply buried center drainage ditch used in a conventional road tunnel are not needed.

Description

technical field [0001] The invention relates to water conservancy engineering road tunnels, in particular to an antifreeze method for water conservancy engineering road tunnels in cold regions. Background technique [0002] When constructing road tunnels in cold regions, it is necessary to ensure that no water accumulates behind the tunnel lining and that the drains do not freeze. The current traditional method is to lay thermal insulation boards on the outside or inside of the tunnel lining, and set up a deep-buried central drainage ditch or a cold-proof drainage tunnel below the depth of the frozen soil in the center of the road surface. Meet the antifreeze requirements of highway tunnels. However, for road tunnels used in water conservancy projects in cold regions, due to the small traffic flow, the above-mentioned traditional anti-freezing methods for road tunnels not only increase the project investment, but also the construction of the above-mentioned anti-freezing me...
