mm，非開挖工程將鉆孔底部泥漿掏凈，下沉管井，用集水總管將管井連接起來。并在孔壁與管井之間埃3~15mm礫石作為過濾層。吸水管用直徑50~100 mm膠皮管或鋼管，其底端應(yīng)在設(shè)計(jì)降水位的較低水位以下。鑄鐵管可用管內(nèi)活塞拉孔及空壓機(jī)清洗。對(duì)其他材料的管并用空壓機(jī)清洗，洗至渭水為止。在排水時(shí)需經(jīng)常對(duì)電動(dòng)機(jī)等設(shè)備進(jìn)行檢查，并觀測水位，記錄流量。為了保護(hù)環(huán)境并促進(jìn)社會(huì)進(jìn)步，建議選擇非開挖施工術(shù)來守護(hù)家園！</p><div
