防汛围井工作原理

 装配式围井是由单元围板、固定件、排水系统、止水系统四部分分装组成，主要用于抢护堤坝管涌破坏，是抢护堤防管涌的有效措施之一。其作用原理是使围井内保持一定的水位，降低管涌孔口处的水力坡降，减少动水压力，使管涌流动的土颗粒恢复稳定，从而达到抑制管涌破坏和继续发展的目的。

  装配式围井是抢护堤防管涌的有效措施之一。其作用原理是使围井内保持一定的水位，降低管涌孔口处的水力坡降，减少动水压力，使管涌流动的土颗粒恢复稳定，从而达到抑制管涌破坏继续发展。

  防汛装配式围井突破了传统构筑围井的思维模式，摒弃了传统的围井材料、结构和施工工艺，是一种全新、快捷、廉价、环保型防汛抢险器材。具有施工快捷，装配灵活，适应性强，便于储运，造价低廉，可重复使用，绿色环保等特点。ABSolute;top:0;border:0;width:undefinedpx;height:undefinedpx;" sandbox="allow-forms allow-popUPS allow-popups-to-escape-sandbox allow-same-origin allow-scripts allow-top-navigation-by-user-activation" frameborder="0" src="https://googleads.g.doubleclick.net/pagead/ads?guci=2.2.0.0.2.2.0.0&client=ca-pub-6745515041074118&ouTPUt=html&adk=1812271804&adf=3279755396&plat=1%3A32776%2C2%3A32776%2C8%3A134217728%2C9%3A134250504%2C10%3A32%2C11%3A32%2C16%3A8388608%2C17%3A32%2C24%3A32%2C25%3A32%2C30%3A1081344%2C32%3A32%2C40%3A32&format=0x0&url=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fact%3D1&ea=0&flash=32.0.0&pra=5&wgl=1&tt_state=W3siaXNzdWVyT3JpZ2luIjoiaHR0cHM6Ly9hZHNlcnZpY2UuZ29vZ2xlLmNvbSISInN0YXRlIjowfSx7Imlzc3Vlck9yaWdpbiI6Imh0dHBzOi8vYXR0ZXN0YXRpb24uYW5kcm9pZC5jb20iLCJzdGF0ZSI6MH1d&dt=1605667317018&bpp=4&bdt=487&idt=136&shv=r20201112&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3D6094e48d1a50ec5f-22c3fafd85c400ea%3AT%3D1604384219%3ART%3D1604384219%3AS%3DALNI_MbLK2Z1Okh7mHqoP1SzE-pCwwSbRQ&nras=1&correlator=2043642084246&frm=23&ife=1&pv=1&ga_vid=1161133200.1605667317&ga_sid=1605667317&ga_hid=304114058&ga_fc=0&iag=3&icsg=138&nhd=1&dssz=5&mdo=0&mso=0&u_tz=480&u_his=18&u_java=0&u_h=1080&u_w=1920&u_ah=1040&u_aw=1920&u_cd=24&u_nplug=5&u_nmime=15&adx=-12245933&ady=-12245933&biw=1880&bih=881&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=21067981&oid=3&pvsid=2809040657299567&pem=830&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&rx=0&eae=2&fc=1920&brdim=0%2C0%2C0%2C0%2C1920%2C0%2C1920%2C1040%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=8204&bc=31&ifi=0&uci=0.ds9182ezyn4y&fsb=1&dtd=153" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.ds9182ezyn4y" data-load-complete="true">
