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(工字形(xing),U形(xing)避水樁)出(chu)租、鋼板樁打拔施工、圍堰施工,同時就挖(wa)掘機、拌合機、平地(di)機、壓路機等機械。
鋼(gang)板(ban)樁(zhuang)優點高(gao)(gao)質量(高(gao)(gao)強(qiang)(qiang)度,輕(qing)型(xing),隔水性良好(hao))施工(gong)(gong)簡單,工(gong)(gong)期縮短(duan)耐(nai)久性良好(hao),鋼(gang)板(ban)樁(zhuang)壽命20-50年建設費用(yong)便宜互(hu)換性良好(hao),可重復使(shi)用(yong)3-5次施工(gong)(gong)具(ju)有(you)顯著的環保(bao)效果(guo),大(da)量減少(shao)了取土(tu)(tu)量和混(hun)凝土(tu)(tu)的使(shi)用(yong)量,有(you)效地保(bao)護了土(tu)(tu)地資源救災搶險(xian)的時(shi)效性較(jiao)強(qiang)(qiang),如防(fang)洪(hong)、塌方、塌陷、流沙(sha)等(deng)
鋼(gang)板(ban)(ban)(ban)樁當基坑較深、地(di)下水位較高且未施(shi)工降水時,采(cai)用鋼(gang)板(ban)(ban)(ban)樁作為(wei)(wei)支護結(jie)構,既(ji)可擋土、防(fang)水,還可防(fang)止流砂的發(fa)生。板(ban)(ban)(ban)樁支撐可分為(wei)(wei)無(wu)錨板(ban)(ban)(ban)樁(懸臂(bei)式(shi)板(ban)(ban)(ban)樁)和有錨板(ban)(ban)(ban)樁。常(chang)用的鋼(gang)板(ban)(ban)(ban)樁為(wei)(wei)U型鋼(gang)板(ban)(ban)(ban)樁,又稱(cheng)拉森鋼(gang)板(ban)(ban)(ban)樁。
鋼(gang)板(ban)(ban)樁(zhuang)圍(wei)堰是常用(yong)(yong)(yong)的(de)一種(zhong)板(ban)(ban)樁(zhuang)圍(wei)堰。鋼(gang)板(ban)(ban)樁(zhuang)是帶有鎖口的(de)一種(zhong)型鋼(gang),其(qi)截面有直板(ban)(ban)形(xing)、槽(cao)形(xing)及Z形(xing)等,有各(ge)種(zhong)大小尺(chi)寸及聯鎖形(xing)式。常見的(de)有拉(la)爾(er)森(sen)式,拉(la)克萬(wan)納式等。鋼(gang)板(ban)(ban)樁(zhuang)強度(du)高,容易打(da)入堅硬(ying)土層;可在(zai)深水(shui)中施工(gong),必(bi)要(yao)時加斜支(zhi)撐成為一個圍(wei)籠(long)。防水(shui)性能好,能按(an)需(xu)要(yao)組成各(ge)種(zhong)外形(xing)的(de)圍(wei)堰,并可多次重復使用(yong)(yong)(yong),因此,它的(de)用(yong)(yong)(yong)途廣(guang)泛。鋼(gang)板(ban)(ban)樁(zhuang)的(de)實用(yong)(yong)(yong)價值(zhi)在(zai)很多新產品的(de)革新制作中得到了(le)體現,例如:一些特殊的(de)焊(han)接(jie)而(er)成的(de)建筑物;通過液壓振(zhen)動打(da)樁(zhuang)機而(er)做成的(de)金屬板(ban)(ban);密封結(jie)合的(de)水(shui)閘以(yi)及工(gong)廠涂料的(de)處理。
鋼(gang)(gang)(gang)板(ban)樁(zhuang)有(you)各種型號,鋼(gang)(gang)(gang)板(ban)樁(zhuang)主要是(shi)為(wei)了區分國(guo)內的槽鋼(gang)(gang)(gang),因(yin)為(wei)槽鋼(gang)(gang)(gang)也(ye)有(you)很多人習慣稱作鋼(gang)(gang)(gang)板(ban)樁(zhuang)圍堰(yan)是(shi)使用(yong)鋼(gang)(gang)(gang)板(ban)樁(zhuang)逐根(gen)插(cha)打,鋼(gang)(gang)(gang)板(ban)樁(zhuang)之間相互咬接,后封(feng)閉成一(yi)個整體,可(ke)以擋住外側的水土。
