滨州蒲城新堤建于1983年,全长4447m。此堤段1+500～2+500(1000m)属黄河水利委员会在编险点,堤身多为砂性土修筑,渗透力强,易发生渗水、管涌等险情,96.8洪水期间,大堤偎水深2m 左右,背河堤脚及下部堤坡多处渗水。1999年汛前黄委会安排对蒲城新堤1+500～2+500堤段加固,采用垂直铺塑防渗(堤基为垂直铺塑截渗,堤身铺设复合土工膜)。垂直铺塑是利用特制开沟造槽机械,在堤基形成窄而深的沟槽,将塑料薄膜垂直埋入,形成以塑料薄膜为主的防渗帷幕,以消除渗漏、管
Binzhou Pucheng new embankment was built in 1983, a total length of 4447m. The embankment 1 +500 ~ 2 +500 (1000m) belongs to the Yellow River Conservancy Commission in the insurance point, the embankment mostly sandy soil construction, penetration, prone to water seepage, piping and other dangerous conditions, 96.8 during the flood embankment deep water 2m or so, back river embankment foot embankment and the lower part of multiple seepage. Before the flood season in 1999, the Yellow River Committee arranged to reinforce the 1 + 500-2 + 500 embankment section of Pucheng New Dyke by adopting vertical plastic seepage control (embankment vertical seepage plastic infiltration and embankment laying composite geomembrane). Vertical plastic shop is the use of special slotting slotting machine, forming a narrow and deep trench in the embankment, the plastic film buried vertically to form a plastic film-based anti-seepage curtain to eliminate leakage, the tube
