甘肃文县天池渠引水上山渠道,由于流经的地方土层薄、岩石多,地下水位不稳定,开始引水时渗漏现象很严重。在渠道粗通之后,立即转入检查、加固工作,经过不断研究和试验,采取挖、夯、砌、塞、灌、盖、漫等措施进行处理,效果很好。(一)挖:将土石方上的裂缝和洞穴一次挖深一米上下,根据土质,进行筑填;(二)夯:筑填处理时,用黄粘泥土或黑粘泥土,分层夯填,夯实夯严;(三)砌:在溜沙坡和渗漏严重的渠道上,除用黄泥黑泥夯填外,并用石块干砌一层石墙,以免渠水冲刷,筑填失效;(四)塞:在石头衬砌的渠道上,采用黄毛绒草沿缝细塞,通水后黄毛绒草生根长蔓,可以防止渗漏,减少冲刷;(五)灌:用以上办法还不能防止或减少渗漏时,就
Gansu Tianxian County Diversion channel up the mountain, due to flow through the local soil thin, rocky, groundwater level instability, began to divert water leakage is very serious. After the thoroughfare of the channel, it is immediately transferred to the inspection and reinforcement work. After continuous research and experimentation, measures such as digging, ramming, stuffing, plugging, filling, covering and diffusing are taken and the effect is very good. (A) digging: the earthwork cracks and caves digging a depth of one meter up and down, according to soil quality, construction and filling; (two) ram: construction and filling treatment, with yellow clay or black clay, layered ram filling, (3) Construction: On slippery slopes and serious seepage channels, in addition to using black mud and black mud ramming filling, and using dry stone paving a layer of stone walls, so as to avoid canal water scouring, building fill failure; (D) plug: in the stone lining of the channel, the use of yellow plush grass along the cracks along the plug, the water after the yellow plush grass roots grow, can prevent leakage, reduce erosion; (e) irrigation: the above method can not prevent or reduce Leakage, on
