本文選題：高速公路　切入點：綠化隔離帶　出處：《大連海事大學》2014年碩士論文

【摘要】：隨著高速公路快速發(fā)展,綠化隔離帶的安全、美觀作用越來越受到重視。目前絕大數高速公路綠化隔離帶的灌溉仍沿用人工水車拉水的辦法,效率低、安全隱患大。安全、靈活、快捷、效率高、節(jié)水型的綠化隔離帶灌溉技術將是我國今后發(fā)展趨勢。本論文通過資料收集、調研、專家咨詢、室內外實驗等多種方法,對高速公路綠化隔離帶植物需水規(guī)律、灌水技術選型、灌溉控制技術、灌溉管網安全評價、材料選型與管網布置方式進行試驗研究。針對吉林省的水文、氣象和土質條件,提出綠化隔離帶主要植物耗水量、灌溉定額、灌水周期和灌水定額；通過室外試驗,從對植物生長的影響、綜合成本和工程耐久性等角度綜合考慮,提出適宜節(jié)水灌溉技術形式及控制技術；通過對高速公路灌溉管道進行受力分析和防凍害及適宜埋深試驗,研究得出管道埋深深度指標和防凍脹指標,并最終提出適應高速公路特點的管材類型及布置方式。
[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.
