Description

A kind of road surface initiatively is incubated anti-skidding facility and job practices thereof
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 road surface and initiatively be incubated anti-skidding facility and job practices thereof.
Background technology
Winter road surface accumulated snow to freeze and cause phenomenons such as traffic congestion, traffic accident be problem demanding prompt solution among the human lives.Especially seasonal tunnel in cold area highway, owing to be located in area, the mountain ridge as the one of which, the long-term water outlet of its surrounding environment becomes stream, 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 like artificial removing method, mechanical removal method, chemical snow melt method and thermodynamic method.
The promptly artificial accumulated snow of removing of artificial removing method, this method efficient is lower, and for busy traffic, promptly 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, leans on the road maintenance workman to carry out the manual work snow removing, and is barely satisfactory especially.
For the mechanical removal method, because of 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 import merely, can not satisfy the demand.And though the effect of big machinery when removing thicker accumulated snow is obvious, like 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 the road surface is bigger, use snow removal with machine separately, not only can not thoroughly remove ice and snow, and automobile goes on ice and snow road, the adhesive power on wheel and road surface is still very low, causes traffic accident easily.
Chemistry snow melt method is a kind of method that the mode through salting or other environment-friendly snowmelt agents removes the snow.Mainly be through reducing the melting point of snow, making 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 pavement snow melting ice and has successively experienced the developing stage that adopts technology such as underground heat, solar heat-preservation system and conducting concrete.According to the difference of employed heat energy source, can be divided into following several kinds: the heat energy that the energy that the energy that produces as the ground heat pipe method of heat energy source, with the infrared lamp heating with heat energy produces according to heating, with the electrothermal wire heating as the infrared lamp of heat energy source produces as the fluid heating of heat energy source, with the fiber heating power that is added in the 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 certain limitation separately: geothermal method receives 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 kinds of 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 the disaster problem of ice and snow road closure energetically, and on the whole function singleness, output is few, technical level is low, on operability, has very big limitation.
