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(ban)樁(工字(zi)形(xing),U形(xing)避水(shui)樁)出租(zu)、鋼板(ban)樁打(da)拔施(shi)工、圍堰施(shi)工,同(tong)時(shi)就挖掘機(ji)、拌合機(ji)、平(ping)地機(ji)、壓路機(ji)等機(ji)械。
鋼(gang)板樁優點高質量(高強(qiang)度(du),輕(qing)型,隔水性良好(hao))施(shi)工簡單,工期縮短(duan)耐久性良好(hao),鋼(gang)板樁壽命(ming)20-50年建設費用便宜互(hu)換性良好(hao),可(ke)重復使(shi)用3-5次施(shi)工具有顯著(zhu)的環(huan)保效果,大量減少了(le)取土量和混凝土的使(shi)用量,有效地保護了(le)土地資(zi)源救災搶險的時(shi)效性較強(qiang),如(ru)防洪(hong)、塌(ta)方、塌(ta)陷、流沙等
鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)樁(zhuang)(zhuang)當基坑較(jiao)深、地(di)下水(shui)位較(jiao)高且未施(shi)工(gong)降水(shui)時,采用(yong)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)樁(zhuang)(zhuang)作為(wei)支護結構,既可擋土、防水(shui),還可防止流砂的(de)發生(sheng)。板(ban)(ban)(ban)(ban)(ban)樁(zhuang)(zhuang)支撐(cheng)可分(fen)為(wei)無錨(mao)(mao)板(ban)(ban)(ban)(ban)(ban)樁(zhuang)(zhuang)(懸臂式板(ban)(ban)(ban)(ban)(ban)樁(zhuang)(zhuang))和有錨(mao)(mao)板(ban)(ban)(ban)(ban)(ban)樁(zhuang)(zhuang)。常用(yong)的(de)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)樁(zhuang)(zhuang)為(wei)U型鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)樁(zhuang)(zhuang),又稱拉(la)森(sen)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)樁(zhuang)(zhuang)。
鋼板(ban)樁(zhuang)圍(wei)(wei)堰是常(chang)用(yong)的一種(zhong)(zhong)板(ban)樁(zhuang)圍(wei)(wei)堰。鋼板(ban)樁(zhuang)是帶有(you)(you)鎖口(kou)的一種(zhong)(zhong)型鋼,其截面有(you)(you)直板(ban)形(xing)(xing)(xing)、槽形(xing)(xing)(xing)及Z形(xing)(xing)(xing)等,有(you)(you)各種(zhong)(zhong)大小尺寸及聯鎖形(xing)(xing)(xing)式。常(chang)見的有(you)(you)拉爾森式,拉克萬納(na)式等。鋼板(ban)樁(zhuang)強度高(gao),容易打(da)入堅硬土層;可在(zai)深水(shui)中施工,必要時加斜支撐成為一個圍(wei)(wei)籠。防水(shui)性能(neng)好,能(neng)按需要組成各種(zhong)(zhong)外形(xing)(xing)(xing)的圍(wei)(wei)堰,并可多次(ci)重(zhong)復(fu)使(shi)用(yong),因(yin)此,它的用(yong)途廣泛。鋼板(ban)樁(zhuang)的實用(yong)價值在(zai)很(hen)多新(xin)產品的革新(xin)制作中得到了(le)體現(xian),例如:一些特殊的焊接而成的建筑物;通過液(ye)壓振動(dong)打(da)樁(zhuang)機而做成的金屬板(ban);密封結合的水(shui)閘以及工廠(chang)涂料的處理。
鋼(gang)板(ban)(ban)樁有各種(zhong)型號,鋼(gang)板(ban)(ban)樁主要是(shi)為(wei)了區分國內(nei)的槽鋼(gang),因為(wei)槽鋼(gang)也有很多人習(xi)慣稱作鋼(gang)板(ban)(ban)樁圍堰是(shi)使(shi)用鋼(gang)板(ban)(ban)樁逐根插打,鋼(gang)板(ban)(ban)樁之間(jian)相(xiang)互咬接,后封(feng)閉成一(yi)個整體,可(ke)以擋住外側的水土。
