固井
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)
