Built In Snow Melting Device Study On Design Of Pervious Concrete Ground

China northern winter snow cover and icing phenomenon is serious, urban and rural transportation and the safety of the people travel to bring adverse effect, each year in the area have to deploy a large number of manpower and material resources to clean up. Currently, the main use of manual and mechanical clearance or snowmelt agent is sprayed to snow. The former has low working efficiency, except snow is not complete and work interruption of traffic and other shortcomings; the latter will produce reinforced, steel fiber corrosion and spalling of the road surface, the effects of roadside plant growth is, resulting in hardening of the soil barren, durability and environmental problems. In view of the above problems, this paper studies the water permeable concrete floor system of the ice melting device. The main research contents of this paper are as follows:(1) Study on fine concrete base materialsStudy on reasonably selecting corresponding materials. Through the test and pre tested with, on the basis of trial with a, combined with engineering experience and other research data, constantly optimize the adjustment of the proportion of each component configuration, the test mix selected conform to the mix ratio, and the compressive strength, self sealing shite and freezing and thawing corresponding test. Through compression test. Determination of fine concrete compressive strength; through self compacting properties test and evaluation fine fresh concrete performance; through the test chamber fast freeze-thaw test and research of fine grained concrete resistance of freezing and thawing.(2) Study on the application of concrete floor heating performance with built-in snow melting deviceCompared at present mainly in addition to the advantages and disadvantages of the methods of ice and snow, considering the system at the end of the heating device, select the carbon fiber heating as a built-in deicing and snow melting device, the choice of silica gel coat carbon fiber wire are studied; study the hotline in the substrate different distance and depth layout effect on the surface temperature distribution of, making the concrete thin and thick two specimens, design different spacing concrete thin plate's temperature rise test, different depth of concrete slab temperature rise test and concrete in different substrate conductivity contrast test, study on built in deicing and snow melting device concrete floor heating performance.(3) The overall design of the permeability of the groundConsider the concrete ground of the built-in deicing and snow melting device in use. face of freeze-thaw problem was studied by organized drainage, seepage of urban drainage system structure design and transformation, in order to improve the permeability properties of monolithic ground; ground system permeability influence factors analysis; design water seepage pipeline to ensure in the inflow of large amounts of precipitation, the water along the pipeline quickly dispersed to the surrounding soil, and when soil water beyond the overflow design water level, water to low slope or drainage pipe network; design for water seepage pipeline and the existing drainage network connected to the connection port.(4) The popularization value of the built in snow melting device of the permeable concrete groundFrom the economic cost, snow melting effect and green environmental protection aspects of pervious concrete floor of the built-in deicing and snow melting device expansion benefit analysis, to estimate the initial investment of the device, and then makes a brief analysis on the problems of the existing; explain to the existing should be the situation, on the promotion and application of the value analysis.
