鋼板樁特殊的使用性能,在抗震救災中的修復工程中大量進口采用,并且得到了快速的發展。隨著我國經濟的快速發展,鋼板樁擋墻作為一種快捷、高效、環保的建筑工法得以認可并發展。哈爾濱鋼板樁租賃是(shi)集鋼板樁(工(gong)字形,U形避水樁)出(chu)租、鋼板樁打拔(ba)施工(gong)、圍堰(yan)施工(gong),同時就挖(wa)掘機(ji)、拌合機(ji)、平(ping)地(di)機(ji)、壓(ya)路機(ji)等(deng)機(ji)械。
鋼板樁優點高(gao)質量(liang)(高(gao)強度,輕型,隔水性(xing)良好(hao))施(shi)工(gong)簡單,工(gong)期縮短耐久性(xing)良好(hao),鋼板樁壽命20-50年建(jian)設(she)費用(yong)便宜(yi)互換性(xing)良好(hao),可重復使用(yong)3-5次施(shi)工(gong)具有顯著的(de)環保效(xiao)果,大量(liang)減(jian)少(shao)了取土量(liang)和混凝土的(de)使用(yong)量(liang),有效(xiao)地保護了土地資(zi)源救災搶險的(de)時效(xiao)性(xing)較(jiao)強,如(ru)防洪(hong)、塌方(fang)、塌陷、流沙等
鋼(gang)(gang)(gang)板(ban)(ban)(ban)樁(zhuang)當基坑較(jiao)深、地下水位較(jiao)高且未(wei)施工降水時,采用(yong)鋼(gang)(gang)(gang)板(ban)(ban)(ban)樁(zhuang)作(zuo)為(wei)(wei)支護結構,既(ji)可擋土、防水,還可防止流砂的發生。板(ban)(ban)(ban)樁(zhuang)支撐可分(fen)為(wei)(wei)無(wu)錨(mao)板(ban)(ban)(ban)樁(zhuang)(懸(xuan)臂式板(ban)(ban)(ban)樁(zhuang))和有錨(mao)板(ban)(ban)(ban)樁(zhuang)。常用(yong)的鋼(gang)(gang)(gang)板(ban)(ban)(ban)樁(zhuang)為(wei)(wei)U型鋼(gang)(gang)(gang)板(ban)(ban)(ban)樁(zhuang),又稱拉森鋼(gang)(gang)(gang)板(ban)(ban)(ban)樁(zhuang)。
鋼板(ban)(ban)(ban)樁(zhuang)圍(wei)堰是常(chang)用(yong)的(de)(de)(de)(de)(de)一種板(ban)(ban)(ban)樁(zhuang)圍(wei)堰。鋼板(ban)(ban)(ban)樁(zhuang)是帶有鎖口(kou)的(de)(de)(de)(de)(de)一種型鋼,其截面有直(zhi)板(ban)(ban)(ban)形(xing)、槽形(xing)及(ji)Z形(xing)等,有各(ge)種大小尺寸及(ji)聯鎖形(xing)式(shi)。常(chang)見的(de)(de)(de)(de)(de)有拉爾森式(shi),拉克萬納式(shi)等。鋼板(ban)(ban)(ban)樁(zhuang)強(qiang)度高,容易打入堅硬土(tu)層;可(ke)在深水中(zhong)施工,必要時加斜支撐成(cheng)(cheng)為(wei)一個圍(wei)籠。防(fang)水性能好,能按需要組成(cheng)(cheng)各(ge)種外形(xing)的(de)(de)(de)(de)(de)圍(wei)堰,并可(ke)多(duo)次重復使用(yong),因此,它的(de)(de)(de)(de)(de)用(yong)途廣泛。鋼板(ban)(ban)(ban)樁(zhuang)的(de)(de)(de)(de)(de)實用(yong)價值(zhi)在很多(duo)新產(chan)品的(de)(de)(de)(de)(de)革(ge)新制作中(zhong)得到了(le)體(ti)現,例如:一些(xie)特殊的(de)(de)(de)(de)(de)焊接而成(cheng)(cheng)的(de)(de)(de)(de)(de)建(jian)筑物(wu);通過液壓(ya)振動打樁(zhuang)機而做(zuo)成(cheng)(cheng)的(de)(de)(de)(de)(de)金(jin)屬板(ban)(ban)(ban);密封結合的(de)(de)(de)(de)(de)水閘以及(ji)工廠涂料的(de)(de)(de)(de)(de)處(chu)理。
鋼(gang)(gang)(gang)板(ban)(ban)樁(zhuang)有各種(zhong)型號(hao),鋼(gang)(gang)(gang)板(ban)(ban)樁(zhuang)主要是為了區分國內的槽鋼(gang)(gang)(gang),因為槽鋼(gang)(gang)(gang)也有很(hen)多人習(xi)慣稱(cheng)作(zuo)鋼(gang)(gang)(gang)板(ban)(ban)樁(zhuang)圍(wei)堰是使用鋼(gang)(gang)(gang)板(ban)(ban)樁(zhuang)逐根插打,鋼(gang)(gang)(gang)板(ban)(ban)樁(zhuang)之(zhi)間相(xiang)互(hu)咬接,后封閉(bi)成一個整體,可以擋(dang)住外(wai)側的水土。
