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(shi)集鋼板樁(zhuang)(工(gong)字形(xing),U形(xing)避(bi)水樁(zhuang))出租、鋼板樁(zhuang)打拔施工(gong)、圍堰施工(gong),同時就挖(wa)掘(jue)機(ji)(ji)、拌合機(ji)(ji)、平地(di)機(ji)(ji)、壓路機(ji)(ji)等機(ji)(ji)械。
鋼板樁優點高(gao)(gao)質量(liang)(高(gao)(gao)強(qiang)度,輕型,隔水(shui)性(xing)良(liang)好(hao))施工(gong)簡單,工(gong)期縮(suo)短耐久性(xing)良(liang)好(hao),鋼板樁壽命20-50年建設(she)費用便宜互換(huan)性(xing)良(liang)好(hao),可重(zhong)復使(shi)用3-5次施工(gong)具有(you)顯著的環(huan)保(bao)效果,大(da)量(liang)減(jian)少了取土(tu)量(liang)和混凝土(tu)的使(shi)用量(liang),有(you)效地(di)保(bao)護了土(tu)地(di)資源救(jiu)災搶險的時效性(xing)較(jiao)強(qiang),如(ru)防洪、塌(ta)方、塌(ta)陷、流沙等
鋼(gang)板(ban)(ban)(ban)(ban)(ban)樁(zhuang)(zhuang)當基坑較(jiao)(jiao)深、地下水位(wei)較(jiao)(jiao)高且未(wei)施(shi)工降水時,采用(yong)鋼(gang)板(ban)(ban)(ban)(ban)(ban)樁(zhuang)(zhuang)作(zuo)為支護結構,既可(ke)擋土、防(fang)水,還可(ke)防(fang)止流砂的發生。板(ban)(ban)(ban)(ban)(ban)樁(zhuang)(zhuang)支撐可(ke)分為無錨板(ban)(ban)(ban)(ban)(ban)樁(zhuang)(zhuang)(懸臂式板(ban)(ban)(ban)(ban)(ban)樁(zhuang)(zhuang))和有錨板(ban)(ban)(ban)(ban)(ban)樁(zhuang)(zhuang)。常用(yong)的鋼(gang)板(ban)(ban)(ban)(ban)(ban)樁(zhuang)(zhuang)為U型鋼(gang)板(ban)(ban)(ban)(ban)(ban)樁(zhuang)(zhuang),又稱拉(la)森鋼(gang)板(ban)(ban)(ban)(ban)(ban)樁(zhuang)(zhuang)。
鋼(gang)(gang)板(ban)樁(zhuang)圍(wei)堰(yan)是常用的(de)(de)一種(zhong)(zhong)板(ban)樁(zhuang)圍(wei)堰(yan)。鋼(gang)(gang)板(ban)樁(zhuang)是帶有鎖口的(de)(de)一種(zhong)(zhong)型(xing)鋼(gang)(gang),其截面有直板(ban)形(xing)、槽(cao)形(xing)及Z形(xing)等,有各(ge)種(zhong)(zhong)大小尺寸及聯鎖形(xing)式。常見的(de)(de)有拉(la)爾森式,拉(la)克萬納(na)式等。鋼(gang)(gang)板(ban)樁(zhuang)強度高,容易打入堅硬土層;可(ke)在深水(shui)(shui)中施工,必要(yao)時加(jia)斜支撐成為一個(ge)圍(wei)籠。防水(shui)(shui)性(xing)能(neng)(neng)好,能(neng)(neng)按需(xu)要(yao)組成各(ge)種(zhong)(zhong)外(wai)形(xing)的(de)(de)圍(wei)堰(yan),并可(ke)多次重(zhong)復使用,因(yin)此,它(ta)的(de)(de)用途(tu)廣泛。鋼(gang)(gang)板(ban)樁(zhuang)的(de)(de)實用價值在很多新產(chan)品的(de)(de)革新制作中得到(dao)了(le)體現,例(li)如:一些特(te)殊的(de)(de)焊接而(er)成的(de)(de)建筑物(wu);通過液壓振動打樁(zhuang)機而(er)做(zuo)成的(de)(de)金(jin)屬板(ban);密(mi)封結合的(de)(de)水(shui)(shui)閘以及工廠涂料的(de)(de)處理。
鋼(gang)板(ban)樁(zhuang)有(you)各種型號,鋼(gang)板(ban)樁(zhuang)主要(yao)是(shi)為(wei)了區分國內(nei)的槽(cao)鋼(gang),因為(wei)槽(cao)鋼(gang)也有(you)很多人(ren)習(xi)慣稱作(zuo)鋼(gang)板(ban)樁(zhuang)圍堰是(shi)使用(yong)鋼(gang)板(ban)樁(zhuang)逐根插打(da),鋼(gang)板(ban)樁(zhuang)之間(jian)相互咬接(jie),后封閉成一(yi)個整(zheng)體,可以擋住外側的水土。
