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(ban)樁(zhuang)(工字形(xing),U形(xing)避水樁(zhuang))出租、鋼板(ban)樁(zhuang)打(da)拔施工、圍堰(yan)施工,同時就挖掘機(ji)(ji)、拌合機(ji)(ji)、平地機(ji)(ji)、壓路機(ji)(ji)等機(ji)(ji)械。
鋼板樁(zhuang)優點高質(zhi)量(liang)(liang)(高強(qiang)度,輕型,隔水性良(liang)好(hao))施工(gong)簡單,工(gong)期縮短(duan)耐(nai)久性良(liang)好(hao),鋼板樁(zhuang)壽命20-50年建設費用(yong)便宜互換性良(liang)好(hao),可(ke)重復(fu)使(shi)用(yong)3-5次施工(gong)具有(you)顯(xian)著的環保(bao)效(xiao)果,大(da)量(liang)(liang)減少了取土量(liang)(liang)和混(hun)凝土的使(shi)用(yong)量(liang)(liang),有(you)效(xiao)地保(bao)護了土地資源救災搶(qiang)險的時效(xiao)性較(jiao)強(qiang),如防洪、塌(ta)方、塌(ta)陷、流沙等
鋼板(ban)(ban)(ban)(ban)樁(zhuang)(zhuang)(zhuang)當(dang)基坑較(jiao)深(shen)、地下水位(wei)較(jiao)高且未施工降(jiang)水時,采用(yong)鋼板(ban)(ban)(ban)(ban)樁(zhuang)(zhuang)(zhuang)作為支護結構(gou),既(ji)可(ke)(ke)擋(dang)土、防水,還可(ke)(ke)防止(zhi)流(liu)砂的發生。板(ban)(ban)(ban)(ban)樁(zhuang)(zhuang)(zhuang)支撐可(ke)(ke)分為無錨板(ban)(ban)(ban)(ban)樁(zhuang)(zhuang)(zhuang)(懸臂式板(ban)(ban)(ban)(ban)樁(zhuang)(zhuang)(zhuang))和(he)有錨板(ban)(ban)(ban)(ban)樁(zhuang)(zhuang)(zhuang)。常用(yong)的鋼板(ban)(ban)(ban)(ban)樁(zhuang)(zhuang)(zhuang)為U型鋼板(ban)(ban)(ban)(ban)樁(zhuang)(zhuang)(zhuang),又稱拉森(sen)鋼板(ban)(ban)(ban)(ban)樁(zhuang)(zhuang)(zhuang)。
鋼(gang)板(ban)(ban)(ban)(ban)(ban)樁(zhuang)圍(wei)(wei)堰是(shi)常(chang)用(yong)的(de)一(yi)種板(ban)(ban)(ban)(ban)(ban)樁(zhuang)圍(wei)(wei)堰。鋼(gang)板(ban)(ban)(ban)(ban)(ban)樁(zhuang)是(shi)帶有(you)(you)鎖(suo)口的(de)一(yi)種型鋼(gang),其截面(mian)有(you)(you)直板(ban)(ban)(ban)(ban)(ban)形、槽形及(ji)(ji)Z形等,有(you)(you)各種大小(xiao)尺寸及(ji)(ji)聯鎖(suo)形式。常(chang)見(jian)的(de)有(you)(you)拉爾森(sen)式,拉克萬納式等。鋼(gang)板(ban)(ban)(ban)(ban)(ban)樁(zhuang)強度高,容(rong)易打(da)入堅硬土層;可在深水中施工(gong),必要時(shi)加斜(xie)支撐成為一(yi)個圍(wei)(wei)籠。防(fang)水性能好(hao),能按需要組成各種外形的(de)圍(wei)(wei)堰,并可多次重復(fu)使(shi)用(yong),因此,它(ta)的(de)用(yong)途廣泛。鋼(gang)板(ban)(ban)(ban)(ban)(ban)樁(zhuang)的(de)實用(yong)價值在很多新產品的(de)革(ge)新制作中得到了體現,例如:一(yi)些(xie)特(te)殊的(de)焊(han)接而(er)成的(de)建筑物(wu);通過(guo)液壓振動(dong)打(da)樁(zhuang)機(ji)而(er)做成的(de)金(jin)屬板(ban)(ban)(ban)(ban)(ban);密(mi)封結合的(de)水閘以及(ji)(ji)工(gong)廠涂料(liao)的(de)處理。
鋼(gang)(gang)板(ban)樁(zhuang)有各種型(xing)號,鋼(gang)(gang)板(ban)樁(zhuang)主(zhu)要是(shi)為了區分國內的槽鋼(gang)(gang),因為槽鋼(gang)(gang)也有很多(duo)人(ren)習慣稱作鋼(gang)(gang)板(ban)樁(zhuang)圍堰是(shi)使用鋼(gang)(gang)板(ban)樁(zhuang)逐根(gen)插打(da),鋼(gang)(gang)板(ban)樁(zhuang)之間相互咬接(jie),后封閉成一個整體,可以擋住外(wai)側的水(shui)土。
