Description
Technical field
The invention belongs to the highway construction technical field, relate to highway facilities and building method thereof, be specifically related to a kind of active heat-insulation antiskid facility for road surfaces and job practices thereof.
Background technology
Winter road snow to freeze and cause the phenomenons such as traffic congestion, traffic accident be problem demanding prompt solution in the human lives.Especially seasonal tunnel in cold area highway, because it generally is located in area, the mountain ridge, the long-term water outlet of its surrounding environment becomes stream, and the factor such as underground water causes the tunnel portal road section surface often to have accumulated snow to freeze in addition, brings very high danger to driving.Should this and given birth to the method for multiple removal ice and snow, common as: manually remove method, mechanical removal method, chemical thaw method and thermodynamic method.
Artificial removing method i.e. the artificial accumulated snow of removing, and this method efficient is lower, and for busy traffic, namely vehicle is many, and accumulated snow very short time, this method was difficult to satisfy its actual needs by grinding compacting.And highway in most cases passes through meagrely-populated area, manually removes the snow by the road maintenance workman, and is barely satisfactory especially.
For the mechanical removal method, because domestic professed machine in this respect is not a lot, and China is vast in territory, and the climatic environment of various places is not quite similar, and relies on merely import, can not satisfy the demand.And though the successful of big machinery when removing thicker accumulated snow, as slight snow, the effect of snow removal with machine is undesirable, economic benefit is not good yet.When temperature is low, because the adhesion stress between ice and road surface is larger, use separately snow removal with machine, not only can not thoroughly remove ice and snow, and automobile travels on ice and snow road, the adhesive power on wheel and road surface is still very low, easily causes traffic accident.
The chemical thaw method is a kind of method that the mode by salting or other environment-friendly snowmelt agents removes the snow.Be mainly the melting point of avenging by reduction, make snow melt.These method materials needed, manpower are all higher, have significant limitation.
Thermodynamic method is to use heat energy to make the method for snow melt.This method is used for the research of snow-ice melting system and has successively experienced the developing stage that adopts the technology such as underground heat, solar heat-preservation system and conducting concrete.According to the difference of the heat energy source that uses, can be divided into following several: the heat energy that the energy of sending out the energy thermogenetic and producing according to heating, with the electrothermal wire heating as the infrared lamp of heat energy source as the geothermal tube method of heat energy source, with infrared lamp with heat energy produces as the fluid heating method of heat energy source, with the fiber heating power that is added in pavement concrete as the heating wire method of heat energy source, with the heat energy of high temperature fluid is as the conducting concrete method of heat energy source etc.Have separately certain limitation: geothermal method is subject to the geothermal heat source restriction; The solar heat-preservation system cost is too high; Conducting concrete is inscribed between the technical existence of Control of Voltage; These several snow melt technology are restricted in practical engineering application.
In sum, the shortcoming of existing deicing method is mainly: its method essence is all comparatively passive, can not in time tackle energetically the disaster problem of ice and snow road closure, and on the whole function singleness, output is few, technical level is low, has very large limitation on operability.
