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板樁(zhuang)(工(gong)字形,U形避水樁(zhuang))出租、鋼板樁(zhuang)打拔(ba)施工(gong)、圍(wei)堰施工(gong),同時就挖掘機、拌(ban)合機、平地機、壓(ya)路機等機械。
鋼(gang)板樁優(you)點高(gao)質量(liang)(高(gao)強度,輕(qing)型,隔(ge)水性(xing)良(liang)好(hao))施工簡單(dan),工期縮短耐久(jiu)性(xing)良(liang)好(hao),鋼(gang)板樁壽命20-50年建設費用(yong)便(bian)宜互換(huan)性(xing)良(liang)好(hao),可重復使用(yong)3-5次施工具有(you)顯(xian)著的(de)(de)環保效(xiao)果,大量(liang)減少了(le)取土量(liang)和混凝土的(de)(de)使用(yong)量(liang),有(you)效(xiao)地保護了(le)土地資源救(jiu)災搶(qiang)險的(de)(de)時效(xiao)性(xing)較強,如防洪、塌(ta)方(fang)、塌(ta)陷、流沙等
鋼(gang)(gang)板(ban)(ban)樁(zhuang)(zhuang)當基坑(keng)較(jiao)深、地下(xia)水位較(jiao)高且未施工(gong)降水時,采用鋼(gang)(gang)板(ban)(ban)樁(zhuang)(zhuang)作為(wei)支護結構,既可(ke)(ke)擋土、防水,還(huan)可(ke)(ke)防止流(liu)砂的發生。板(ban)(ban)樁(zhuang)(zhuang)支撐可(ke)(ke)分為(wei)無錨板(ban)(ban)樁(zhuang)(zhuang)(懸臂(bei)式板(ban)(ban)樁(zhuang)(zhuang))和(he)有錨板(ban)(ban)樁(zhuang)(zhuang)。常用的鋼(gang)(gang)板(ban)(ban)樁(zhuang)(zhuang)為(wei)U型鋼(gang)(gang)板(ban)(ban)樁(zhuang)(zhuang),又稱(cheng)拉森鋼(gang)(gang)板(ban)(ban)樁(zhuang)(zhuang)。
鋼(gang)板(ban)(ban)樁圍(wei)堰(yan)(yan)是常用(yong)(yong)的(de)(de)(de)一(yi)種(zhong)(zhong)板(ban)(ban)樁圍(wei)堰(yan)(yan)。鋼(gang)板(ban)(ban)樁是帶有(you)鎖口的(de)(de)(de)一(yi)種(zhong)(zhong)型(xing)鋼(gang),其截面有(you)直板(ban)(ban)形、槽(cao)形及Z形等(deng),有(you)各種(zhong)(zhong)大(da)小(xiao)尺寸及聯鎖形式(shi)。常見的(de)(de)(de)有(you)拉爾森(sen)式(shi),拉克萬(wan)納(na)式(shi)等(deng)。鋼(gang)板(ban)(ban)樁強(qiang)度(du)高,容易打(da)入(ru)堅硬土層;可在深(shen)水(shui)(shui)(shui)中(zhong)(zhong)施工(gong),必(bi)要時加斜支撐(cheng)成(cheng)(cheng)為(wei)一(yi)個圍(wei)籠。防水(shui)(shui)(shui)性能好,能按需(xu)要組成(cheng)(cheng)各種(zhong)(zhong)外形的(de)(de)(de)圍(wei)堰(yan)(yan),并可多(duo)次(ci)重(zhong)復使用(yong)(yong),因此,它的(de)(de)(de)用(yong)(yong)途廣泛(fan)。鋼(gang)板(ban)(ban)樁的(de)(de)(de)實用(yong)(yong)價(jia)值(zhi)在很(hen)多(duo)新產品的(de)(de)(de)革新制作(zuo)中(zhong)(zhong)得到了體現,例如(ru):一(yi)些特殊的(de)(de)(de)焊接而(er)(er)成(cheng)(cheng)的(de)(de)(de)建筑物;通過液壓振動打(da)樁機而(er)(er)做(zuo)成(cheng)(cheng)的(de)(de)(de)金屬(shu)板(ban)(ban);密封結(jie)合的(de)(de)(de)水(shui)(shui)(shui)閘以及工(gong)廠涂料的(de)(de)(de)處理。
鋼(gang)(gang)板(ban)(ban)樁(zhuang)(zhuang)有(you)(you)各種(zhong)型(xing)號,鋼(gang)(gang)板(ban)(ban)樁(zhuang)(zhuang)主要是為了(le)區分國內的(de)槽鋼(gang)(gang),因為槽鋼(gang)(gang)也有(you)(you)很多(duo)人(ren)習慣稱作鋼(gang)(gang)板(ban)(ban)樁(zhuang)(zhuang)圍堰是使(shi)用鋼(gang)(gang)板(ban)(ban)樁(zhuang)(zhuang)逐根插打,鋼(gang)(gang)板(ban)(ban)樁(zhuang)(zhuang)之間相互咬接,后封閉成(cheng)一個整體(ti),可(ke)以(yi)擋住(zhu)外側(ce)的(de)水土。
