href="http://www.lnhlrd.com/hdpesljcj/"><strong>HDPE塑料檢查井</strong></a>在施工或安裝過(guò)程常見(jiàn)的問(wèn)題，今天小編在這給大家列舉僅供參考：<br /> 一、HDPE塑料檢查井筒需要加高怎么解決？塑料檢查井井筒是采用HDPE雙壁波紋管，每根波紋管都有一個(gè)擴口，用擴口直接承插井筒就可以增加高度。其他實(shí)壁管采用井筒接頭增加。<br /> 二、最多可以開(kāi)多少孔？污水檢查井價(jià)格|1000塑料檢查井|600塑料檢查井正林建材當匯入的出戶(hù)管管徑小于等于110時(shí)，井筒可以開(kāi)3個(gè)孔，大于等于160時(shí)，在不同平面上也可以開(kāi)3個(gè)孔。<br /> 三、橡膠圈主要用于哪里？井筒和井座或者井座和管道連接承插口部位的柔性連接部件，用于檢查井密封、防水，可抗沉降及拉伸，是塑料檢查井各部件完美連接的重要部件，通常采用橡膠材質(zhì)制作。<br /> 四、怎么選用膠圈？由于各個(gè)廠(chǎng)家的管子外徑不同，所以不同的管道外徑采用不同厚度的大小膠圈進(jìn)行密封定徑。</span></p> <p style="text-align: center;"> <a href="http://www.lnhlrd.com/hdpesljcj/"><img alt="HDPE塑料檢查井的常見(jiàn)問(wèn)題" src="/uploads/allimg/200815/1-200Q5155621491.jpg" /></a></p> <p> <span style="font-size:16px;">五、在HDPE塑料檢查井實(shí)際應用中容易堵塞嗎？塑料檢查井井座內壁光滑流暢，排水性能出色，改變了先進(jìn)的塑料管道存在傳統磚砌井的節點(diǎn)，雨污水排放效率是傳統井的3倍以上，堵塞性大大的降低。<br /> 六、能下井操作嗎？塑料檢查井不需要下井操作，改變和顛覆傳統磚砌井的習慣，所以就采用國際上先進(jìn)的清通理念實(shí)施機械清通。<br /> 七、塑料檢查井的基礎需要做混凝土不？不需要，做混凝土不符合塑料檢查井適應土質(zhì)均勻沉降的條件；當埋設管道沉降時(shí)，檢查井不能相對應的沉降就會(huì )導致井座由于受力不一致而損壞。<br /> 八、安裝HDPE塑料檢查井基礎有什么要求？答：檢查井應安裝在密實(shí)的地基土層上，或是在開(kāi)挖井坑后經(jīng)處理密實(shí)的地基上，檢查井基礎一般采用砂礫石墊層基礎。塑料檢查井的功能有五點(diǎn):節地、節能、節水、節材、環(huán)保。 </span><br /> </p> <br /> </div>  <div id="fj7fhjf"
