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(ji)鋼(gang)板樁(工(gong)字(zi)形(xing),U形(xing)避水樁)出租(zu)、鋼(gang)板樁打拔施工(gong)、圍堰(yan)施工(gong),同時就挖掘機(ji)(ji)(ji)、拌合機(ji)(ji)(ji)、平地(di)機(ji)(ji)(ji)、壓路(lu)機(ji)(ji)(ji)等(deng)機(ji)(ji)(ji)械。
鋼(gang)板(ban)樁優(you)點高質(zhi)量(liang)(高強度,輕(qing)型,隔(ge)水性良(liang)好(hao))施工(gong)簡單(dan),工(gong)期(qi)縮短耐久性良(liang)好(hao),鋼(gang)板(ban)樁壽命20-50年建設(she)費(fei)用便宜(yi)互換性良(liang)好(hao),可重復使(shi)用3-5次施工(gong)具有顯著(zhu)的環保效(xiao)果(guo),大量(liang)減少(shao)了取(qu)土量(liang)和混(hun)凝土的使(shi)用量(liang),有效(xiao)地保護(hu)了土地資源救(jiu)災搶(qiang)險的時效(xiao)性較強,如防洪、塌(ta)方、塌(ta)陷(xian)、流沙等(deng)
鋼(gang)板(ban)(ban)(ban)樁(zhuang)當基坑較(jiao)深、地下水位(wei)較(jiao)高且未施工降水時,采用鋼(gang)板(ban)(ban)(ban)樁(zhuang)作為支護(hu)結構(gou),既可(ke)(ke)擋土、防水,還(huan)可(ke)(ke)防止(zhi)流砂的(de)發生。板(ban)(ban)(ban)樁(zhuang)支撐可(ke)(ke)分(fen)為無錨板(ban)(ban)(ban)樁(zhuang)(懸臂式(shi)板(ban)(ban)(ban)樁(zhuang))和有錨板(ban)(ban)(ban)樁(zhuang)。常用的(de)鋼(gang)板(ban)(ban)(ban)樁(zhuang)為U型(xing)鋼(gang)板(ban)(ban)(ban)樁(zhuang),又稱拉(la)森鋼(gang)板(ban)(ban)(ban)樁(zhuang)。
鋼(gang)板(ban)(ban)樁(zhuang)圍(wei)堰是(shi)(shi)常用的(de)(de)(de)一種(zhong)(zhong)板(ban)(ban)樁(zhuang)圍(wei)堰。鋼(gang)板(ban)(ban)樁(zhuang)是(shi)(shi)帶有(you)鎖(suo)口的(de)(de)(de)一種(zhong)(zhong)型鋼(gang),其截(jie)面有(you)直(zhi)板(ban)(ban)形(xing)、槽形(xing)及(ji)Z形(xing)等,有(you)各種(zhong)(zhong)大小尺(chi)寸及(ji)聯(lian)鎖(suo)形(xing)式。常見(jian)的(de)(de)(de)有(you)拉爾森式,拉克萬納式等。鋼(gang)板(ban)(ban)樁(zhuang)強(qiang)度高,容易打(da)入堅硬土層;可(ke)在深水(shui)中施工(gong),必要(yao)時加斜支撐成(cheng)(cheng)為一個(ge)圍(wei)籠(long)。防水(shui)性能(neng)(neng)好,能(neng)(neng)按需要(yao)組成(cheng)(cheng)各種(zhong)(zhong)外形(xing)的(de)(de)(de)圍(wei)堰,并可(ke)多次重復使用,因(yin)此,它的(de)(de)(de)用途廣泛。鋼(gang)板(ban)(ban)樁(zhuang)的(de)(de)(de)實用價值在很多新產品的(de)(de)(de)革新制(zhi)作中得到了(le)體現,例如:一些(xie)特殊的(de)(de)(de)焊(han)接而成(cheng)(cheng)的(de)(de)(de)建筑物;通(tong)過液壓振動(dong)打(da)樁(zhuang)機而做成(cheng)(cheng)的(de)(de)(de)金屬板(ban)(ban);密封(feng)結(jie)合(he)的(de)(de)(de)水(shui)閘以及(ji)工(gong)廠涂(tu)料的(de)(de)(de)處理(li)。
鋼(gang)(gang)板(ban)(ban)樁(zhuang)有(you)各(ge)種型號,鋼(gang)(gang)板(ban)(ban)樁(zhuang)主(zhu)要是為(wei)了區分(fen)國內的(de)槽鋼(gang)(gang),因為(wei)槽鋼(gang)(gang)也有(you)很多人(ren)習慣稱作鋼(gang)(gang)板(ban)(ban)樁(zhuang)圍堰(yan)是使(shi)用鋼(gang)(gang)板(ban)(ban)樁(zhuang)逐根插打,鋼(gang)(gang)板(ban)(ban)樁(zhuang)之間(jian)相互咬接,后封閉成一(yi)個整(zheng)體(ti),可以擋住外側的(de)水土(tu)。
