常州鉆井(jing)

深(shen)井(jing)施(shi)工程序 A.中(zhong)型深(shen)井(jing)由PPR塑(su)料管材(cai)直徑(jing)為(wei)(wei)160mm，鉆孔(kong)為(wei)(wei)300mm，周(zhou)圍孔(kong)距間填(tian)黃(huang)沙，根據地質和地形確定(ding)(ding)深(shen)度(du)和水量。 B.大型的深(shen)井(jing)有高(gao)壓、高(gao)溫(wen)水泥制品管，井(jing)管直徑(jing)360mm,每根長(chang)度(du)為(wei)(wei)4米(mi)，兩頭連接(jie)鋼箍，兩管直接(jie)電(dian)焊連接(jie)，鉆孔(kong)直徑(jing)為(wei)(wei)600mm,深(shen)度(du)可達10-1000米(mi)，周(zhou)圍孔(kong)距間填(tian)充石(shi)英沙，水量多(duo)少根據貴公司用(yong)量決定(ding)(ding)，確保用(yong)水。

        清晨、黃昏或冬季有水(shui)(shui)(shui)(shui)氣(qi)上(shang)升(sheng)如(ru)霧(wu)，或巖石邊長有青苔(tai)，及下(xia)(xia)雨后經(jing)常有水(shui)(shui)(shui)(shui)來的(de)地(di)(di)(di)方，都會有水(shui)(shui)(shui)(shui)源。5.春(chun)季解(jie)凍早，冬季結凍晚，下(xia)(xia)雪(xue)融化快(kuai)的(de)地(di)(di)(di)面(mian)上(shang)，地(di)(di)(di)下(xia)(xia)水(shui)(shui)(shui)(shui)源一般都好。6.夏季的(de)早晨或晚上(shang)，蚊(wen)子成團的(de)地(di)(di)(di)方，地(di)(di)(di)下(xia)(xia)可能(neng)水(shui)(shui)(shui)(shui)源旺(wang)。7.秋(qiu)季早晨霧(wu)氣(qi)直升(sheng)的(de)地(di)(di)(di)方，地(di)(di)(di)下(xia)(xia)水(shui)(shui)(shui)(shui)位(wei)(wei)高。8.冬季結凍后，地(di)(di)(di)面(mian)裂縫的(de)地(di)(di)(di)方凝有白霜，地(di)(di)(di)下(xia)(xia)水(shui)(shui)(shui)(shui)位(wei)(wei)高。9.觀察坡地(di)(di)(di)上(shang)的(de)草木(mu)，如(ru)春(chun)天發芽早，天旱(han)又不枯萎，附一定有水(shui)(shui)(shui)(shui)源。10.在預(yu)備打井的(de)地(di)(di)(di)面(mian)上(shang)，挖出一些二尺左右深的(de)小坑(keng)，可以觀測(ce)地(di)(di)(di)下(xia)(xia)水(shui)(shui)(shui)(shui)的(de)情況。
