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)鋼板樁(工(gong)字形(xing),U形(xing)避(bi)水樁)出租、鋼板樁打(da)拔施工(gong)、圍堰(yan)施工(gong),同時就挖掘機(ji)、拌合機(ji)、平地機(ji)、壓(ya)路機(ji)等機(ji)械。
鋼(gang)板(ban)樁(zhuang)優點高(gao)質(zhi)量(高(gao)強度,輕型,隔(ge)水性(xing)良好(hao))施工簡單,工期縮(suo)短耐久性(xing)良好(hao),鋼(gang)板(ban)樁(zhuang)壽命20-50年建設(she)費用便(bian)宜互(hu)換(huan)性(xing)良好(hao),可(ke)重復使用3-5次(ci)施工具有顯著的環(huan)保(bao)效果,大量減(jian)少(shao)了取土(tu)量和混凝土(tu)的使用量,有效地(di)保(bao)護了土(tu)地(di)資源(yuan)救災搶險的時效性(xing)較強,如防洪、塌方、塌陷(xian)、流沙等
鋼板(ban)(ban)(ban)(ban)樁當基坑較(jiao)深、地下水位較(jiao)高且未施工(gong)降(jiang)水時,采(cai)用(yong)鋼板(ban)(ban)(ban)(ban)樁作(zuo)為(wei)支(zhi)護結構,既可(ke)擋(dang)土、防水,還(huan)可(ke)防止流砂的發生。板(ban)(ban)(ban)(ban)樁支(zhi)撐可(ke)分為(wei)無錨板(ban)(ban)(ban)(ban)樁(懸臂(bei)式板(ban)(ban)(ban)(ban)樁)和有錨板(ban)(ban)(ban)(ban)樁。常用(yong)的鋼板(ban)(ban)(ban)(ban)樁為(wei)U型鋼板(ban)(ban)(ban)(ban)樁,又稱(cheng)拉(la)森鋼板(ban)(ban)(ban)(ban)樁。
鋼(gang)板(ban)(ban)(ban)樁(zhuang)圍(wei)堰(yan)(yan)是常用(yong)的(de)一(yi)(yi)種(zhong)板(ban)(ban)(ban)樁(zhuang)圍(wei)堰(yan)(yan)。鋼(gang)板(ban)(ban)(ban)樁(zhuang)是帶(dai)有(you)(you)鎖口(kou)的(de)一(yi)(yi)種(zhong)型鋼(gang),其截(jie)面有(you)(you)直板(ban)(ban)(ban)形、槽形及(ji)(ji)Z形等,有(you)(you)各種(zhong)大小尺(chi)寸及(ji)(ji)聯鎖形式。常見的(de)有(you)(you)拉(la)爾森式,拉(la)克萬納式等。鋼(gang)板(ban)(ban)(ban)樁(zhuang)強度(du)高,容易打(da)入(ru)堅(jian)硬土層;可在深水(shui)中施工,必要時加(jia)斜支撐成(cheng)(cheng)為一(yi)(yi)個圍(wei)籠。防水(shui)性(xing)能好,能按(an)需要組成(cheng)(cheng)各種(zhong)外形的(de)圍(wei)堰(yan)(yan),并可多(duo)次(ci)重復使用(yong),因此,它的(de)用(yong)途廣(guang)泛。鋼(gang)板(ban)(ban)(ban)樁(zhuang)的(de)實用(yong)價值在很(hen)多(duo)新(xin)產品的(de)革新(xin)制作中得到了體現,例如:一(yi)(yi)些(xie)特殊(shu)的(de)焊接(jie)而成(cheng)(cheng)的(de)建筑物;通過(guo)液壓振動打(da)樁(zhuang)機而做成(cheng)(cheng)的(de)金屬板(ban)(ban)(ban);密封(feng)結合的(de)水(shui)閘以(yi)及(ji)(ji)工廠涂料的(de)處理。
鋼(gang)板(ban)(ban)樁(zhuang)(zhuang)有各種(zhong)型號,鋼(gang)板(ban)(ban)樁(zhuang)(zhuang)主要是(shi)為了區分國內的槽鋼(gang),因為槽鋼(gang)也有很多人(ren)習慣(guan)稱(cheng)作(zuo)鋼(gang)板(ban)(ban)樁(zhuang)(zhuang)圍堰是(shi)使用鋼(gang)板(ban)(ban)樁(zhuang)(zhuang)逐根插打(da),鋼(gang)板(ban)(ban)樁(zhuang)(zhuang)之間相互(hu)咬接,后封閉成一個(ge)整體,可以擋住外側的水土(tu)。
