| اهداف اصلی احداث شبکههای آبیاری، بهرهوری بهینه از منابع آبی- خاکی میباشد. بهسازی کانال انتقال آب دراین شبکهها، نقش مهمی در تأمین آب و افزایش کارایی شبکه دارد. در دهههای گذشته انجام عملیات اصلاح، بازسازی و پوشش بتنی کانال خاکی با ظرفیت بیش از50 مترمکعب در ثانیه، معمولاً بیشترین سهم هزینههای سرمایهگذاری، بهرهبرداری و نگهداری را به خود اختصاص داده است. ازاینرو استفاده از تکنولوژیهای نوین و مقرون بهصرفه، با لحاظ اصول فنی بهینه هیدرولیکی- اقتصادی همواره مورد توجه بوده است. فناوری مورد استفاده در این پژوهش، انتقال جریان آب در حین بهرهبرداری بهواسطهی سازه دیواره تیغهای جداکننده سیار به طول 100 الی 150 متر متشکل از به هم پیوستن پانلهای متعددی به ابعاد (3*0/2*3) متر از جنس فایبرگلاس که نصب بر روی سازه خرپای سورتمهای به ابعاد (1*0/8*6) متر است، انجام میگیرد. سازه با قرار گرفتن درآکس کف کانال با چرخاندن بالها تحت زاویه 45 و یا90 درجه به سمت دیواره جانبی از ورود آب به مقطع محصور شده جلوگیری مینماید. با انجام عملیات خشکاندازی اصلاح و بازسازی امکانپذیر میشود. نتایج بررسیها نشان داد، هزینههای عملیات اجرایی اصلاح و بازسازی کانال اصلی در روش پیشنهادی در حدود 2/7 برابر مقرون بهصرفهتر از روش کانال انحرافی موقت مرسوم میباشد. النهایه امکان بهکارگیری سازه پیشنهادی با حفظ شرایط اصول فنی و بهینه هیدرولیکی- اقتصادی برای اجرای عملیات پوشش بتنی در مقاطع خاکی کانال اصلی بدون قطع جریان آب، فراهم گردید. | ||

| Extended Abstract Introuction This study aims to examine building modern irrigation networks to provide the possibility of productivity of water and soil resources by creating facilities, in which the optimal technical principles and criteria of hydraulic and economic design are observed. In this regard, the main water transfer channel plays a vital and exceptional role in supplying the required water for agricultural lands covered by the network and for the prosperity of the regional and national agricultural economy. Covering the water transmission channels in operation is always one of the numerous problems and problems of operation and maintenance of large irrigation networks in the world. In Iran, due to the major issues and problems of exploitation in the lands covered by modern networks, such as land drainage due to water leakage from the bodies of earthen canals, concrete covering of canals has always been considered to prevent water wastage, and it is on the agenda. The deputy of water resources affairs of the Ministry of Energy and regional water companies was established. The main canal of the South Moghan irrigation network in Iran with a transfer capacity of 80 cubic meters per second, the main channel of Upper Garabagh with a capacity of 110 cubic meters per second and the main water transfer channel of Upper Shirvan with a capacity of 85 cubic meters per second in the Republic of Azerbaijan are among them. Material and Methods The withdrawal of water needed by the Moghan irrigation and drainage network from the Aras River is directed through the Mil and Moghan diversion dam before entering the main channel to a sediment catchment basin to trap suspended sediments in it. This calm sediment collection pond with a maximum water intake of 95 cubic meters per second has four rectangular units and each unit consists of three galleries, 15 cubic meters of which are returned to the river after washing, and the rest enters the main channel. In the current state, due to the reduction of vegetation in the middle basin of the Aras River at a distance of 260 km from the Aras Reservoir Dam upstream of the Mil and Moghan Diversion Dam and the subsequent increase in the concentration of suspended load in the Aras River, the trapping efficiency of the suspended load in the sedimentation basin has decreased to its minimum value. For this reason, sediments exceeding the permissible limit of 18 to 25 g/L enter the water transfer channel. Even though more than 45 years of the useful life of the network have passed, covering operations of the main channel with materials, such as impermeable soil (compaction of bed soil, cover with a thin compacted layer of clay, cover with bentonite) or concrete cover to prevent washing water and reduce water loss from the earthen body of the main channel has happened very little and locally. Results and Discussion Considering the necessity of realizing the research objectives, the feasibility of using the proposed method to carry out the executive operations of improvement, reconstruction, and concrete covering of the soil section of the canal, without interrupting the water flow in the main water transmission channel of South Moghan from its kilometer 1 to 11, was conducted (Hasanpour and Tabatabai, 2010). The method of constructing a temporary diverting channel along the main channel by constructing earthen dikes in the cross-section of the main channel to cut off the water flow within the scope of operational operations of the enclosed sections between the dikes and directing the required water flow by creating a diverting section in the side wall of the channel upstream of the earthen dike into the temporary diversion channel and re-directing the water flow through the end earthen dyke downstream into the main channel for the implementation of repair and reconstruction operations and concrete coating in several operating intervals of the earth section of the channel without interrupting the water flow by spending exorbitant costs of the construction operation of the temporary diversion channel and the concrete cover of the main channel were done. Therefore, due to the imposition of excessive and unconventional financial burden in the method of using a temporary diversion channel on the implementation of the main channel modification and reconstruction plan, to reduce the excessive conventional costs, the new method of "wall structure of mobile separating blades" as a solution suitable and cost-effective for its use and application in the repair and reconstruction of the canal was suggested. The regional water company also promised to assist in the application and use of the new technology proposed to operate the project in the main Moghan canal, based on the urgent need and necessity of the issue. In this method, the minimum cost is 2.7 times lower than the cost of constructing a diversion channel per unit length (1 km). Also, in carrying out dredging operations, cleaning and smoothing the section of the main canal of southern Moghan, similar to the long-boom excavator, which was invented by Professor Telman Hajief to carry out dredging operations in special conditions and channels with large sections, using modern technology, was used. (Hashmi-Shadheni et al., 2016) Conclusions Since the well-known methods and proposals are accompanied by defects even after completion, therefore a new effective method was developed under the title of "mobile separating blade wall method", which is the mechanism of operationalizing the technical and technological parameters of its construction widely. It was investigated and researched. First, the operation of the mobile separating blade wall structure in laboratory conditions was investigated experimentally. The division of the main channel sections in the method of the mobile separating blade wall structure, drying the enclosed operation field, carrying out soil operations, concreting, and its technological technology was presented, and determined, that in this method, carrying out the operation of covering the sections of the water transmission channel using concrete panels Arme will be ready, easier and very affordable. Also, the calculation of the technical and economic comparison indicators of the construction, along with the transfer of the required costs downstream with different methods showed that the mobile dividing wall method is very suitable and economical in terms of technical, technological, and economic aspects in the major repairs and reconstruction of the main channels. The proposed method is a new technique that for its application in production, there will be an urgent need to conduct practical research in nature. Therefore, it is suggested that the presented method be conducted and evaluated for other networks so that all the country's networks can be improved and modified more cost-effectively. | ||
