玻璃鋼夾砂管管端之間接觸面夾角過大處理

玻(bo)璃鋼(gang)夾(jia)砂(sha)管(guan)管(guan)端(duan)之(zhi)間(jian)接觸(chu)面夾(jia)角(jiao)(jiao)由于過大(da)糾(jiu)偏(pian)造(zao)成(cheng)玻(bo)璃鋼(gang)夾(jia)砂(sha)管(guan)兩管(guan)端(duan)之(zhi)間(jian)接觸(chu)面夾(jia)角(jiao)(jiao)過大(da)，這對防(fang)滲性和(he)管(guan)端(duan)應力分布產生(sheng)不利(li)影(ying)響，嚴重(zhong)時將(jiang)對整條(tiao)管(guan)線的(de)(de)穩定(ding)性產生(sheng)不利(li)影(ying)響。出(chu)現(xian)這種情(qing)況應及時采取以下措施加(jia)以解(jie)決(jue)：1頂進過程中(zhong)(zhong)應加(jia)強激(ji)光(guang)定(ding)位監(jian)測(ce)，避免(mian)管(guan)道出(chu)現(xian)較(jiao)大(da)偏(pian)移(yi)。2出(chu)現(xian)較(jiao)大(da)偏(pian)移(yi)時，應采取多次糾(jiu)偏(pian)法(fa)進行糾(jiu)偏(pian)。3在(zai)出(chu)現(xian)接觸(chu)面夾(jia)角(jiao)(jiao)過大(da)的(de)(de)管(guan)端(duan)處設置支撐鋼(gang)環，避免(mian)頂進過程中(zhong)(zhong)夾(jia)角(jiao)(jiao)擴大(da)，甚(shen)至造(zao)成(cheng)管(guan)道軸向失穩。安丘(qiu)玻(bo)璃鋼(gang)有限廠(chang)家(jia)是制造(zao)各種玻(bo)璃鋼(gang)系列的(de)(de)專業生(sheng)產廠(chang),覆蓋20多個省市自治區。并廣(guang)泛適應于油田、化工、給排水(shui)、中(zhong)(zhong)央(yang)空調(diao)、紡(fang)織印染、電力、食品(pin)、郵(you)電、造(zao)紙、防(fang)腐保(bao)溫(wen)和(he)污水(shui)處理工程等,歡迎各界友人來廠(chang)洽(qia)談訂貨。aqblgc玻(bo)璃鋼(gang)夾(jia)砂(sha)管(guan)管(guan)端(duan)之(zhi)間(jian)接觸(chu)面夾(jia)角(jiao)(jiao)過大(da)的(de)(de)處理
