微膨脹性基礎灌漿料

灌(guan)漿材(cai)料(liao)技(ji)術起源于20世紀(ji)70年代(dai)武鋼1.7米(mi)工(gong)(gong)(gong)程中的(de)設備(bei)(bei)安裝座(zuo)漿施工(gong)(gong)(gong)和無(wu)墊(dian)(dian)板(ban)施工(gong)(gong)(gong)工(gong)(gong)(gong)藝。該技(ji)術取(qu)消了傳(chuan)統(tong)中廣泛(fan)使(shi)用的(de)合(he)適的(de)金屬墊(dian)(dian)板(ban)，取(qu)而代(dai)之(zhi)的(de)是設備(bei)(bei)底(di)座(zuo)完全(quan)由基礎混凝(ning)土支撐，使(shi)設備(bei)(bei)底(di)座(zuo)的(de)應力更(geng)加合(he)理。無(wu)墊(dian)(dian)板(ban)施工(gong)(gong)(gong)的(de)核心技(ji)術是使(shi)用無(wu)收縮灌(guan)漿材(cai)料(liao)。由于灌(guan)漿層無(wu)收縮甚至微膨脹，地腳螺栓被張(zhang)緊，以確保設備(bei)(bei)底(di)座(zuo)...
