sealing of drop-shaft bottom to rock
gUJ,ng固井(sealing of drop一shaft bottom to roek)在竖井沉井法掘进中将沉井井筒永久固定的技术。当沉井下沉达到设计深度后,为防止井筒继续下沉或出现位移,需采取加强井壁和土帮的固定措施,以隔离井筒与井外含水层的水力联系,这是沉井施工的最后一道工序。固井采取的主要措施是联接套井与沉井的上口,井筒壁后注浆以增加侧面阻力,砌筑沉井基座以增加正面阻力,最终使井筒保持稳固。 在固井之前,若刃脚坐落的基岩上面无隔水粘土层,则需构筑封底止水垫,以防止井内排水后,发生涌砂冒泥或突水事故。封底后,首先要清除套井与沉井之间的泥浆,然后在其中浇灌片石混凝土,同时将沉井上口的钢筋与套井锁口的钢筋焊接好,并浇灌混凝土,使沉井与套井连成整体。最后,排除井内积水,进行壁后注浆。一般采用分段下行、分段内上行式注浆方法。当采用泥浆护壁减阻时,要先注清水,把泥浆置换出来后,再注水泥浆。井底筑有止水垫时,要进行工作面预注浆。待浆液凝固后,破除封底止水垫,在基岩中砌筑沉井基座。待基座砌好,沉井施工结束,即转入井筒普通法掘进。 (石达民)
