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(工(gong)(gong)字形,U形避(bi)水(shui)樁)出租、鋼板樁打拔施(shi)工(gong)(gong)、圍堰施(shi)工(gong)(gong),同時就挖掘機、拌合機、平(ping)地(di)機、壓路機等機械。
鋼板(ban)樁優點高質量(高強(qiang)度,輕(qing)型,隔水性(xing)(xing)(xing)良好)施工簡(jian)單(dan),工期縮短耐久性(xing)(xing)(xing)良好,鋼板(ban)樁壽命20-50年建設費用(yong)(yong)(yong)便(bian)宜互換性(xing)(xing)(xing)良好,可(ke)重復使用(yong)(yong)(yong)3-5次施工具有顯著(zhu)的(de)環保效(xiao)果(guo),大(da)量減少了取土(tu)量和混凝土(tu)的(de)使用(yong)(yong)(yong)量,有效(xiao)地(di)保護了土(tu)地(di)資源救災搶險的(de)時效(xiao)性(xing)(xing)(xing)較強(qiang),如防(fang)洪、塌方、塌陷(xian)、流沙等(deng)
鋼(gang)(gang)板(ban)(ban)(ban)樁(zhuang)當基坑(keng)較(jiao)深、地下水(shui)位較(jiao)高(gao)且未(wei)施工降水(shui)時,采用鋼(gang)(gang)板(ban)(ban)(ban)樁(zhuang)作為支護結構,既可擋土(tu)、防(fang)水(shui),還可防(fang)止流砂(sha)的(de)發(fa)生。板(ban)(ban)(ban)樁(zhuang)支撐可分為無錨(mao)板(ban)(ban)(ban)樁(zhuang)(懸臂式板(ban)(ban)(ban)樁(zhuang))和有錨(mao)板(ban)(ban)(ban)樁(zhuang)。常用的(de)鋼(gang)(gang)板(ban)(ban)(ban)樁(zhuang)為U型鋼(gang)(gang)板(ban)(ban)(ban)樁(zhuang),又稱拉森鋼(gang)(gang)板(ban)(ban)(ban)樁(zhuang)。
鋼(gang)(gang)板(ban)(ban)(ban)樁(zhuang)(zhuang)圍(wei)(wei)堰是常(chang)用(yong)的一種板(ban)(ban)(ban)樁(zhuang)(zhuang)圍(wei)(wei)堰。鋼(gang)(gang)板(ban)(ban)(ban)樁(zhuang)(zhuang)是帶有鎖口的一種型鋼(gang)(gang),其截面有直板(ban)(ban)(ban)形(xing)、槽(cao)形(xing)及Z形(xing)等(deng),有各(ge)種大小尺(chi)寸及聯(lian)鎖形(xing)式(shi)(shi)。常(chang)見的有拉爾森式(shi)(shi),拉克萬納式(shi)(shi)等(deng)。鋼(gang)(gang)板(ban)(ban)(ban)樁(zhuang)(zhuang)強度高,容(rong)易打(da)入堅硬(ying)土(tu)層(ceng);可在(zai)深水(shui)中施工,必要(yao)時加斜支撐成(cheng)(cheng)為(wei)一個圍(wei)(wei)籠。防水(shui)性(xing)能好(hao),能按需要(yao)組成(cheng)(cheng)各(ge)種外形(xing)的圍(wei)(wei)堰,并可多次重復使用(yong),因此,它(ta)的用(yong)途(tu)廣泛。鋼(gang)(gang)板(ban)(ban)(ban)樁(zhuang)(zhuang)的實用(yong)價值在(zai)很多新產品的革(ge)新制作中得到了體現,例如:一些特殊的焊接而成(cheng)(cheng)的建筑物;通過(guo)液壓振(zhen)動打(da)樁(zhuang)(zhuang)機(ji)而做成(cheng)(cheng)的金屬板(ban)(ban)(ban);密封結合(he)的水(shui)閘(zha)以(yi)及工廠涂料的處理。
鋼板樁有各(ge)種(zhong)型號(hao),鋼板樁主要是為了區(qu)分(fen)國內的槽鋼,因為槽鋼也有很(hen)多人習慣稱作鋼板樁圍(wei)堰是使用鋼板樁逐根插(cha)打,鋼板樁之(zhi)間(jian)相互咬(yao)接,后封閉成一個整(zheng)體,可以擋住外側的水土。
