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集(ji)鋼板樁(zhuang)(工字形(xing),U形(xing)避水樁(zhuang))出(chu)租、鋼板樁(zhuang)打拔施工、圍堰施工,同時就挖掘機(ji)、拌(ban)合機(ji)、平地機(ji)、壓路機(ji)等機(ji)械。
鋼板(ban)樁優點高(gao)質量(liang)(liang)(高(gao)強度,輕型,隔水(shui)性(xing)良(liang)好)施工(gong)(gong)簡單,工(gong)(gong)期(qi)縮短(duan)耐久性(xing)良(liang)好,鋼板(ban)樁壽命(ming)20-50年建(jian)設費用(yong)(yong)便宜(yi)互換(huan)性(xing)良(liang)好,可重(zhong)復使(shi)(shi)用(yong)(yong)3-5次施工(gong)(gong)具有顯著的環保(bao)效(xiao)果(guo),大量(liang)(liang)減(jian)少(shao)了取土(tu)量(liang)(liang)和(he)混凝土(tu)的使(shi)(shi)用(yong)(yong)量(liang)(liang),有效(xiao)地保(bao)護了土(tu)地資源救災搶險的時效(xiao)性(xing)較(jiao)強,如(ru)防洪、塌(ta)方、塌(ta)陷(xian)、流沙(sha)等
鋼(gang)板(ban)(ban)(ban)樁(zhuang)當基坑較深(shen)、地下水(shui)位較高(gao)且未施(shi)工降水(shui)時,采用鋼(gang)板(ban)(ban)(ban)樁(zhuang)作為支護結構,既可擋土、防水(shui),還可防止流砂(sha)的發生。板(ban)(ban)(ban)樁(zhuang)支撐可分為無錨板(ban)(ban)(ban)樁(zhuang)(懸(xuan)臂(bei)式(shi)板(ban)(ban)(ban)樁(zhuang))和(he)有錨板(ban)(ban)(ban)樁(zhuang)。常用的鋼(gang)板(ban)(ban)(ban)樁(zhuang)為U型鋼(gang)板(ban)(ban)(ban)樁(zhuang),又(you)稱拉森鋼(gang)板(ban)(ban)(ban)樁(zhuang)。
鋼(gang)(gang)(gang)板(ban)(ban)樁(zhuang)(zhuang)圍(wei)堰(yan)是(shi)常用的(de)(de)(de)(de)一種(zhong)(zhong)板(ban)(ban)樁(zhuang)(zhuang)圍(wei)堰(yan)。鋼(gang)(gang)(gang)板(ban)(ban)樁(zhuang)(zhuang)是(shi)帶有(you)鎖口的(de)(de)(de)(de)一種(zhong)(zhong)型鋼(gang)(gang)(gang),其截面有(you)直板(ban)(ban)形(xing)(xing)、槽形(xing)(xing)及(ji)Z形(xing)(xing)等,有(you)各種(zhong)(zhong)大(da)小尺寸及(ji)聯鎖形(xing)(xing)式。常見的(de)(de)(de)(de)有(you)拉爾森式,拉克萬(wan)納式等。鋼(gang)(gang)(gang)板(ban)(ban)樁(zhuang)(zhuang)強度高,容(rong)易打(da)入(ru)堅硬土(tu)層;可在深水(shui)中(zhong)施工,必要時加(jia)斜支(zhi)撐成(cheng)(cheng)(cheng)為一個圍(wei)籠。防(fang)水(shui)性能好(hao),能按需(xu)要組成(cheng)(cheng)(cheng)各種(zhong)(zhong)外(wai)形(xing)(xing)的(de)(de)(de)(de)圍(wei)堰(yan),并可多次(ci)重復使用,因(yin)此,它的(de)(de)(de)(de)用途廣泛。鋼(gang)(gang)(gang)板(ban)(ban)樁(zhuang)(zhuang)的(de)(de)(de)(de)實(shi)用價值在很多新產品(pin)的(de)(de)(de)(de)革新制(zhi)作中(zhong)得到(dao)了體(ti)現,例如:一些特殊的(de)(de)(de)(de)焊接而成(cheng)(cheng)(cheng)的(de)(de)(de)(de)建(jian)筑物;通過(guo)液壓(ya)振動打(da)樁(zhuang)(zhuang)機而做成(cheng)(cheng)(cheng)的(de)(de)(de)(de)金屬板(ban)(ban);密封結合的(de)(de)(de)(de)水(shui)閘以及(ji)工廠涂料的(de)(de)(de)(de)處理。
鋼板(ban)樁有各種型號,鋼板(ban)樁主(zhu)要是為了區分國內(nei)的槽(cao)鋼,因為槽(cao)鋼也有很(hen)多人習慣稱作鋼板(ban)樁圍(wei)堰是使用鋼板(ban)樁逐根(gen)插打,鋼板(ban)樁之間(jian)相互(hu)咬(yao)接,后封(feng)閉成一個整體(ti),可以擋住外側的水土。
