Hello. Is there any functional problem by leaving a PVC casing pipe in place after grouting a micropile? Is it necessary for it to be withdrawn at all?
Thank you for your response.
Good morning all. Does anybody have knowledge/experience on the construction of driven soil nailing walls as opossed to dirlled & grouted nails for temporary works? Savings, reliability? Thank you.
Hello. As far as I know, installing soil nails/ground anchors in a staggered grid pattern has advantages regarding load distribution along the facing. Nevertheless, the process can become more time consuming, particularly in slope stabilization as opossed to top-down wall construction.
Do you...
Hello. As you might know, some companies grout between the tendon and the soil in the failure wedge, and some government agencies require such grouting, the unbonded lentgth of the tendon being zero. Then, when these anchors are tested, some of the measured anchor capacity is from the soil...
Hello everyone. I've just found this very interesting reply made by a fine fellow, on a threat posted on this topic a few years back: "In my experience, if the anchor passes its load test, the anchor is acceptable despite low grout test results."
Given that, in addition of the importance of...
Hello everyone. I wonder if you can comment on the applications, advantages, disadvantages, of two-stage ground anchor grouting, leaving a fully bonded free length for corrosion and performance issues of retaining structures, besides mass structures, i.e., dams, etc., Your insights are well...
Hi everyone. I was just wondering how to explain to a client, in a convincing and irrefutable way, why he should not employ standard reinforcing bars, grade 60, 75, in prestressed ground anchors. I know one of the main issues has to be with relaxation of the tendon, but the question that arises...
