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鋼(gang)板樁(工(gong)(gong)字形,U形避(bi)水樁)出租、鋼(gang)板樁打拔施(shi)工(gong)(gong)、圍堰施(shi)工(gong)(gong),同時就挖(wa)掘機(ji)、拌(ban)合(he)機(ji)、平地機(ji)、壓路機(ji)等機(ji)械(xie)。
鋼板樁優點高(gao)質量(liang)(liang)(高(gao)強度,輕型,隔水性良(liang)好(hao))施(shi)工(gong)簡(jian)單(dan),工(gong)期縮短耐久性良(liang)好(hao),鋼板樁壽命20-50年建設費用(yong)便宜互(hu)換性良(liang)好(hao),可重復使(shi)用(yong)3-5次(ci)施(shi)工(gong)具(ju)有(you)顯著的環(huan)保效(xiao)果,大量(liang)(liang)減少(shao)了取土(tu)(tu)量(liang)(liang)和混凝土(tu)(tu)的使(shi)用(yong)量(liang)(liang),有(you)效(xiao)地保護了土(tu)(tu)地資(zi)源救災搶險的時效(xiao)性較強,如防洪、塌方、塌陷、流沙等(deng)
鋼板(ban)(ban)(ban)(ban)樁(zhuang)當基坑較深、地下水(shui)位較高且未(wei)施工降水(shui)時(shi),采用鋼板(ban)(ban)(ban)(ban)樁(zhuang)作為(wei)支護結構,既可擋(dang)土(tu)、防水(shui),還(huan)可防止流砂的發(fa)生。板(ban)(ban)(ban)(ban)樁(zhuang)支撐可分為(wei)無(wu)錨板(ban)(ban)(ban)(ban)樁(zhuang)(懸臂式板(ban)(ban)(ban)(ban)樁(zhuang))和(he)有錨板(ban)(ban)(ban)(ban)樁(zhuang)。常用的鋼板(ban)(ban)(ban)(ban)樁(zhuang)為(wei)U型鋼板(ban)(ban)(ban)(ban)樁(zhuang),又(you)稱拉森鋼板(ban)(ban)(ban)(ban)樁(zhuang)。
鋼板(ban)樁圍(wei)堰(yan)是常(chang)用的(de)(de)一(yi)種(zhong)板(ban)樁圍(wei)堰(yan)。鋼板(ban)樁是帶有鎖(suo)口的(de)(de)一(yi)種(zhong)型(xing)鋼,其截面有直板(ban)形(xing)(xing)(xing)、槽形(xing)(xing)(xing)及(ji)Z形(xing)(xing)(xing)等,有各(ge)種(zhong)大小尺寸及(ji)聯鎖(suo)形(xing)(xing)(xing)式。常(chang)見(jian)的(de)(de)有拉爾(er)森(sen)式,拉克萬納式等。鋼板(ban)樁強度高,容易(yi)打入堅硬(ying)土層;可(ke)在(zai)深水中(zhong)施工,必要時加斜(xie)支撐成(cheng)(cheng)為一(yi)個圍(wei)籠。防(fang)水性(xing)能好,能按需要組成(cheng)(cheng)各(ge)種(zhong)外形(xing)(xing)(xing)的(de)(de)圍(wei)堰(yan),并可(ke)多(duo)次重復使(shi)用,因此,它(ta)的(de)(de)用途(tu)廣(guang)泛。鋼板(ban)樁的(de)(de)實用價值(zhi)在(zai)很多(duo)新產品的(de)(de)革新制作中(zhong)得(de)到了體現,例如:一(yi)些(xie)特殊的(de)(de)焊接(jie)而成(cheng)(cheng)的(de)(de)建筑(zhu)物;通過(guo)液壓振動打樁機而做成(cheng)(cheng)的(de)(de)金屬(shu)板(ban);密封結合的(de)(de)水閘以及(ji)工廠涂料(liao)的(de)(de)處理。
鋼板(ban)(ban)(ban)樁(zhuang)有(you)各種型號,鋼板(ban)(ban)(ban)樁(zhuang)主要是為了(le)區分國內(nei)的(de)槽(cao)鋼,因(yin)為槽(cao)鋼也有(you)很(hen)多人習(xi)慣稱作(zuo)鋼板(ban)(ban)(ban)樁(zhuang)圍堰是使用鋼板(ban)(ban)(ban)樁(zhuang)逐根插打,鋼板(ban)(ban)(ban)樁(zhuang)之間相互咬接,后封(feng)閉成一個整體,可以擋住外側的(de)水土(tu)。
