近日(ri)，中國建(jian)筑工(gong)(gong)程總公司所屬中建(jian)一局“巖溶地(di)區松散土——硬(ying)巖復雜地(di)層(ceng)降水井施工(gong)(gong)技術”經北京市(shi)住(zhu)房和城鄉建(jian)設委(wei)員會鑒(jian)定，整體(ti)達(da)到國內領先水平。
該科(ke)技成果研(yan)發(fa)的“雙動(dong)力頭多功(gong)能潛孔錘鉆(zhan)(zhan)進(jin)技術(shu)”解(jie)(jie)決(jue)了(le)巖(yan)(yan)(yan)溶(rong)(rong)地(di)區松散(san)土(tu)——硬巖(yan)(yan)(yan)復(fu)雜地(di)層(ceng)降(jiang)水井施工(gong)上部松散(san)土(tu)層(ceng)鉆(zhan)(zhan)進(jin)塌孔、下(xia)部堅硬巖(yan)(yan)(yan)層(ceng)鉆(zhan)(zhan)進(jin)效率低下(xia)的難題；研(yan)發(fa)的“復(fu)雜地(di)層(ceng)溶(rong)(rong)洞(dong)穿(chuan)越施工(gong)關鍵技術(shu)”解(jie)(jie)決(jue)了(le)溶(rong)(rong)洞(dong)頂板快速穿(chuan)越、溶(rong)(rong)洞(dong)底板開孔和(he)溶(rong)(rong)洞(dong)破碎(sui)填(tian)充物處理問題，并避免了(le)巖(yan)(yan)(yan)溶(rong)(rong)破碎(sui)帶部位卡(ka)鉆(zhan)(zhan)埋鉆(zhan)(zhan)常發(fa)事故，為土(tu)巖(yan)(yan)(yan)結(jie)合面處的大傾角斜(xie)(xie)巖(yan)(yan)(yan)面和(he)普通(tong)傾斜(xie)(xie)含有軟夾層(ceng)的硬質(zhi)巖(yan)(yan)(yan)層(ceng)鉆(zhan)(zhan)孔施工(gong)提供了(le)思路。
該(gai)成(cheng)(cheng)果形成(cheng)(cheng)發(fa)明專(zhuan)利1項，使用新型專(zhuan)利10項，企業(ye)級工法1項，并在徐州地鐵一號線站(zhan)東廣場站(zhan)和(he)銅(tong)山路站(zhan)得到成(cheng)(cheng)功應(ying)用，取得了良(liang)好的經(jing)濟和(he)社會效益。
