   “逆作(zuo)法永久立柱水平定位(wei)及垂直度控制施工(gong)關(guan)鍵技術研究”通過對傳統校(xiao)正架(jia)(jia)法(fa)(fa)(fa)調(diao)(diao)垂(chui)系(xi)統(tong)進(jin)(jin)行(xing)改進(jin)(jin)，在傳統(tong)校(xiao)正架(jia)(jia)法(fa)(fa)(fa)調(diao)(diao)垂(chui)裝置(zhi)下部增(zeng)設固定(ding)頂進(jin)(jin)螺(luo)栓與鋼護筒進(jin)(jin)行(xing)連(lian)接固定(ding)，保證永(yong)久(jiu)立(li)柱(zhu)調(diao)(diao)垂(chui)過程(cheng)中(zhong)(zhong)新型(xing)校(xiao)正架(jia)(jia)不(bu)發生(sheng)移動。永(yong)久(jiu)立(li)柱(zhu)垂(chui)直度(du)及水平定(ding)位(wei)(wei)調(diao)(diao)節完成(cheng)后，在永(yong)久(jiu)立(li)柱(zhu)上設置(zhi)定(ding)位(wei)(wei)裝置(zhi)，通過定(ding)位(wei)(wei)裝置(zhi)與護筒控(kong)制永(yong)久(jiu)立(li)柱(zhu)下放過程(cheng)不(bu)發生(sheng)偏移，保證永(yong)久(jiu)立(li)柱(zhu)水平定(ding)位(wei)(wei)及垂(chui)直度(du)。永(yong)久(jiu)立(li)柱(zhu)下放至(zhi)設計標高并固定(ding)后，移走新型(xing)校(xiao)正架(jia)(jia)，在施工作(zuo)(zuo)(zuo)業面進(jin)(jin)行(xing)混凝(ning)土澆(jiao)筑，無需增(zeng)加混凝(ning)土輸送泵費用(yong)。在基(ji)坑逆作(zuo)(zuo)(zuo)法(fa)(fa)(fa)永(yong)久(jiu)立(li)柱(zhu)樁施工過程(cheng)中(zhong)(zhong)，采(cai)用(yong)新型(xing)校(xiao)正架(jia)(jia)，具(ju)有(you)設備構造簡單、經久(jiu)耐用(yong)、能有(you)效地(di)保障施工并循環(huan)利用(yong)、節約資源成(cheng)本、工藝成(cheng)熟(shu)、各道(dao)工序(xu)銜(xian)接連(lian)貫、工人易(yi)于掌握操(cao)作(zuo)(zuo)(zuo)、可操(cao)作(zuo)(zuo)(zuo)性強、水平定(ding)位(wei)(wei)及調(diao)(diao)垂(chui)施工效率高等明顯的優(you)勢，該新型校(xiao)正架及工(gong)藝工(gong)法具有廣泛(fan)推廣應用的價值。
