淮河在河南省境内全长437公里,其中在信阳地区境内难于长363.5公里。解放初期由于水文资料短缺,淮河治理标准低,同时随着人口增加,滩地围垦较多,使淮河断面缩小,水位抬高,影响了泄洪,处于“小洪水,高水位,防大汛”的被动局面,部分支流尚未治理。因此,自1970年以来,上级水利部门多次派工程技术人员对淮河进行查勘、规划,于1974年对推干堤防培修加固进行了批复,其治理的原则是以现有工程为基础进行加固除险,继续配套、恢复、巩固、发挥现有工程效益。 淮河干流治理工程在淮委、河南省水利厅的支持下,自1983年开工到1994年6月先后对淮干、支流潢河、史灌河、洪河、泉河堤防培修加固,并修建庄台17
Huaihe River in Henan Province, a total length of 437 km, of which the territory of Xinyang is difficult to grow 363.5 km long. Due to the shortage of hydrological data in the early period of liberation, the standards of Huaihe River regulation were low. Meanwhile, as the population increased, reclamation of beach land was more and the cross section of the Huaihe River shrank and the water level was raised, which affected flood discharge, and was passive in “small flood, high water level and flood prevention” Situation, some tributaries not yet governed. Therefore, since 1970, the superior water conservancy department dispatched engineering technicians to conduct surveys and plans on the Huai River several times and approved the refresher training of embankments in 1974. The principle of its management is based on the existing works In addition to insurance, continue to support, restore, consolidate and give full play to the existing project efficiency. With the support of the Huai River and Henan Provincial Department of Water Resources, the Huaihe River Mainstream Control Project started construction in 1983 and successively in June 1994 to reinforce the Huaigan and tributaries of the Yellow River, the Shuihe River, the Honghe River and the Quanhe Embankment for training and construction Zhuangtai 17
