在全国最大的小商品市场所在地——浙江省义乌市,于6月15-16日召开了由省内外9位农田水利与施工机械专家组成的鉴定会,对该市水电局和佛堂镇水管站共同完成的“砼曲面槽预制工艺及预制机的研究”进行了技术鉴定.专家们认真地审阅了有关技术资料和图纸,赴现场考察了砼U型渠槽预制新工艺及其配套机械的生产过程和用该产品安砌好的渠道运行情况.认为放在薄钢板上先平面浇筑震捣密实,然后弯曲成U形渠槽的新工艺是砼渠道衬砌技术上的新突破.巧妙地利用了砼初凝前的可塑性及时弯曲成型,构思新颖,立意独创,工艺先进,操作简单,质量保证,成本低廉;由平面振动台、弯曲成型 At the site of the nation’s largest small commodity market, Yiwu City, Zhejiang Province, an appraisal meeting of nine farmland water conservancy and construction machinery experts from both inside and outside the province was held on June 15 and June 16. The municipal hydropower station and Fo Tang Town Water Pipe Station Jointly completed “Concrete surface trough prefabrication process and prefabricated machine ” conducted a technical appraisal.Experts carefully reviewed the relevant technical information and drawings, went to the scene inspected the concrete U-shaped channel precast new technology and its supporting machinery Of the production process and the use of the product installation and operation of the channel well run that the first plane placed on the thin steel plate pounding compaction, and then bent into a U-shaped channel of the new technology is a breakthrough in concrete channel lining technology. Cleverly The use of the concrete before the initial setting of the plastic bending and timely molding, innovative ideas, original ideas, advanced technology, simple operation, quality assurance, low cost; from flat vibration table, bending
