【摘要】:随着高速公路快速发展,绿化隔离带的安全、美观作用越来越受到重视。目前绝大数高速公路绿化隔离带的灌溉仍沿用人工水车拉水的办法,效率低、安全隐患大。安全、灵活、快捷、效率高、节水型的绿化隔离带灌溉技术将是我国今后发展趋势。本论文通过资料收集、调研、专家咨询、室内外实验等多种方法,对高速公路绿化隔离带植物需水规律、灌水技术选型、灌溉控制技术、灌溉管网安全评价、材料选型与管网布置方式进行试验研究。针对吉林省的水文、气象和土质条件,提出绿化隔离带主要植物耗水量、灌溉定额、灌水周期和灌水定额;通过室外试验,从对植物生长的影响、综合成本和工程耐久性等角度综合考虑,提出适宜节水灌溉技术形式及控制技术;通过对高速公路灌溉管道进行受力分析和防冻害及适宜埋深试验,研究得出管道埋深深度指标和防冻胀指标,并最终提出适应高速公路特点的管材类型及布置方式。
[Abstract]:With the rapid development of highway, the safety and aesthetic function of green isolation zone are paid more and more attention.At present, the irrigation of most highway greening isolation zone still adopts the method of artificial water truck to pull water, the efficiency is low, the safety hidden danger is big.The irrigation technology of safe, flexible, fast, high efficiency and water saving greening isolation belt will be the development trend of our country in the future.In this paper, through data collection, investigation, expert consultation, indoor and outdoor experiments and other methods, the plant water demand law, irrigation technology selection, irrigation control technology, irrigation pipe network safety evaluation, etc.Material selection and pipe network layout were tested and studied.In view of the hydrological, meteorological and soil conditions of Jilin Province, this paper puts forward the water consumption, irrigation quota, irrigation period and irrigation quota of main plants in the greening separation zone, and through outdoor experiments, from the effects on plant growth,Considering the comprehensive cost and engineering durability, this paper puts forward the suitable water-saving irrigation technology form and control technology, through carrying on the force analysis, the freezing damage prevention and the suitable burying depth test to the expressway irrigation pipeline,The depth index and frost heaving index of pipeline are obtained, and the type and arrangement of pipe material suitable for the characteristics of expressway are put forward.
