随着农业生产的不断发展,近几年来,特别是党的三中全会以来,我省农田水利建筑物配套有了较大的发展。全省已建成小沟以上配套建筑物70多万座。其中,中沟以上配套建筑物20多万座。在建筑物设计、施工及材料等方面,新技术、新经验、新工艺不断涌现,正朝着“轻(轻型)、薄(薄壳)、巧(灵巧)、预(预制、装配)”和“标准化、系列化、工厂化”方向发展。农桥从木桥、砖石拱桥发展到预应力板梁桥、双曲拱桥、三铰拱桥、桁架拱桥,桥台也较普遍地采用了轻型结构;涵、闸、站结构从厚底板、重闸墙、叠梁门,发展到反拱底板、连拱空箱挡土墙,涵闸站结合,一物多用,综合利用;建筑物基础由换砂、打板桩,发展到沉井基础、还填粘土、薄壳基础。一些配套建筑物经过技术革新,可节省材料、降低造价20—40%。徐州地区自1980年3月以来,推广技术革新成果,建重点农水涵、闸、站1695座,建桥梁、渡槽3326座,搞施工技术革新907项,共节约经费257万元。由于新经验、新技术的推广、采用,使配套速度有所加快,工程效益进一步发挥,水利资源得到较好利用,有力地促进了农业生产发展。全省建
With the continuous development of agricultural production, in recent years, especially since the Third Plenary Session of the Party, there has been a great development in the matching of farmland and water conservancy buildings in our province. The province has completed a small ditch more than 70 million supporting buildings. Among them, more than 200,000 supporting structures in the ditch. In the field of building design, construction and materials, new technologies, new experiences and new technologies are constantly emerging and are moving toward “light, thin, thin, clever, prefabricated, ”And“ standardization, serialization, factory-oriented ”direction. Bridge from the bridge, masonry bridge development to the prestressed girder bridge, double curved arch bridge, three hinge arch, truss arch bridge, abutment also more commonly used light structure; Han, gate, station structure from the thick floor, heavy Gate, folding door, the development of the inverted arch floor, arch empty box retaining wall, culvert gate combination, a multi-purpose, comprehensive utilization; building foundation by the sand, playing piles, the development of caisson foundation, also Fill clay, shell foundation. Some supporting buildings after technological innovation, saving materials, reduce the cost of 20-40%. Since March 1980, Xuzhou has promoted achievements in technological innovation and built 1695 key agricultural water culverts, gates and stations, 3,326 bridges and aqueducts, and engaged in technological renovation of 907 projects with a total cost of 2.57 million yuan. As a result of new experience and promotion of new technologies and adoption, the pace of facilities has been accelerated and the project benefits have been further brought into play. Water resources have been better utilized, which has effectively promoted the development of agricultural production. Built in the province
