摘要:
由于受到汛期短期雨水的影响,某供水渠道在混凝土衬砌施工期,在低洼地积水严重下,与河底形成近6 m水位差,其坡面砂化严重,渗透力强,而导致渗流的破坏,也造成了衬砌上浮。利用实例进行原因剖析,从中对设计和施工中的不足提出建设性意见,有助于今后类似工程项目,在特定的工情、水情条件下做好防范,减少渗流的破坏。
Abstract:
Due to the influence of short-term rain in flood season, during the construction period of concrete lining, a water supply channel forms a water level difference of nearly 6 m with the river bottom under the serious water accumulation in low-lying areas. The slope surface was sanding seriously and the permeability was strong, which led to the destruction of seepage, and also caused the lining floating upward. The reasons were analyzed with examples, and constructive suggestions were put forward for the deficiencies in design and construction, which would be helpful to prevent similar projects in the future under specific working conditions and water conditions and reduce seepage damage.
