2009年5月8日 · Very little clearance is required to grout-in a steel pipe to a rock socket. I believe less than an inch. Yes, the grout would need to be pumped in from the bottom up or possibly tremie poured from the bottom up. You would need to get grout inside and outside of the pipe pile in the rock socket length.

2002年10月3日 · Finally, the socket depth is a function of allowable adhesive stress x perimeter of concrete x rock socket depth. Socket depth is a separate limiting factor, not related to pile capacity stated above, except that it has to be the same or greater Others have suggested the pile capacity includes adding the casing capacity to the concrete plus rebar.

2007年5月9日 · The soil/rock lateral stiffness is materially non-linear (P-y curve) but for the small caisson head deflection most SE's are going to tolerate, a linearly elastic soil/rock spring is OK in my opinion. Doing material non-linear FEA based on a geotechnical parameters known to one or two significant figures is "putting lipstick on a pig".
Drilled Caisson/Rock Socket Costs - Bridge engineering - Eng
2004年5月27日 · I am doing a project for a DOT in the Pittsburgh area. I am looking for costs for a 9'-0" drilled caisson rock socket (20' in length) and a 10'-0" drilled caisson (about 40' in length). I found information for smaller diameters but would like to know how much the costs increase for the larger diameter. Thank you!
