田湖大垸灌溉渠系工程改建 规划设计方案一 摘 要 本文通过对田湖大垸现有水利资料进行整理，并结合当地情况，按照灌排相临的方案，重新规划灌溉渠道，以满足水稻灌溉和抗旱的要求，并对排水骨干沟道进行平面布置。疏通和理顺现有通道、提高排渍排涝标准。在现有的排渍沟道的基础上，结合已建的基建排灌站，加宽沟道，使垸内形成深沟大渠。对个别地区提高作物的复种指数，增加产量。加固外河堤防，以抵御洪水的侵袭，确保大垸的安全。并提出今后灌溉规划的设计原则及所要达到的目的。校核现有工程的实际能力，进行规划设计，编制该垸水稻灌溉制度。通过经济分析，估算规划经济效益，论证其可行性，并对规划实施后的利、弊提出预见性的估价。 关键词：田湖大垸；灌溉工程；改建；规划设计 Abstract This article through the dike existing water conservation material carries on the reorganization to Tian Huda, and unifies the local conditions, according to fills the plan which the row is near, plans the irrigation canal, satisfies the paddy rice irrigation and drought resisting request, and carries on the plane layout to the draining water backbone trench. Unblock and the straightening out existing channel, the enhancement draining of floodwater drains waterlogged land the standard. In the existing draining of floodwater trenchs foundation, the union already the capital construction irrigation station which constructs, the broaden trench, causes in the dike to form the gulley big ditch. Enhances the crops to the individual area the multiple-crop index, the gain in yield. Outside the reinforcement the river embankment, resists the flood the attack, guarantees the big dike the security. And proposed from now on irrigation schemes principle of design and must achieve goal. Examines the existing project virtual rating, carries on the plan design, establishes this dike paddy rice irrigation system. Through the economic analysis, the estimate plan economy benefit, proves its feasibility, and after planning the implementation advantage, the shortcoming to propose the foresighted estimate.
