This is part two of the fhwa-nhi-05-039 that covers the following Chapters:.

Worldwide use of micropiles has fhwa-nhi-05-39 since their original development in the s, and in particular fhwa-nhi-05-039 the fhwa-nhi-05-039. In general, micropiles are applicable when there are problems with using conventional deep foundation systems like driven piles, drilled shafts, or augercast piling.

This course presents fhwa-nhi-05-039 general guidelines on micropile selection, application, benefit, design, construction, cost and testing of micropile foundations.

Because fhwa-nhi-05-039 the large file size, we recommend that you first save fhwa-nhi-05-039 file to your computer by right-clicking the mouse and choosing “Save Target As The drilling equipment and fwha-nhi-05-039 methods allow micropiles to be drilled through natural and artificial ground condition with minimal vibration, disturbance fhwa-nih-05-039 noise and at any angle below horizontal.

Mircopiles are fhwa-nhi-05-039 used as elements for foundation support to resist static and dynamic loading fhwa-nhi-05-039, and less frequently as in-situ reinforcements for slope and excavation stability.

Micropile Design and Construction – Part II &Architects

Micropile can be designed as soil frictional fhwa-nhi-05-039 or rock socketed piles either fhwa-mhi-05-039 tension or fhwa-nhi-05-039.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of course materials. Micropiles are commonly made up of high strength steel casing and rebar, but can also be installed in some soil conditions fhwa-nhi-05-039 pressure grouted all-thread self-drilling hollow bar fhwa-nhi-05-039.

This course is intended for geotechnical engineers, civil engineers, structural fhwa-nhi-05-039, construction professionals and contractors. The load is mainly accepted by the steel casing and transferred via the grout to the surrounding rock or soil by high values of interfacial friction with minimal end bearing components, as in the fhwa-nhi-05-039 for ground anchors and soil nails. This two-part series discusses micropile classifications, design concepts, problems fhwa-nhi-05-039 with fhwa-nbi-05-039 common installation methods, specifications, construction control and dhwa-nhi-05-039 of this pile system.

For this course, you are required ffhwa-nhi-05-039 study Chapters 5 and 6 of the fhwa-nhi-05-039 document. A micropile is a small diameter typically 5″ fhwa-nhi-05-039 12″ fhwa-nhi-05-039, drilled and grouted pile with reinforcement. Designed to carry compressive or tensile loads, micropiles are high-performance piles that can achieve working loads over tons and extend to depths fhwa-nhi-05-039 feet.

Your single point of reference for all your Geotechnical Inquiries

This fhwa-nhi-05-039 micropiles the preferred choice of foundation system for retrofitting existing structures in challenging areas. Once you finish fhwa-nhi-05-039 the above course content you need to take a quiz to obtain the PDH credits. The advantages of micropiles are that their installation procedure causes fhwa-nhi-05-039 vibration and noise, they can be installed in difficult ground fhwa-nhi-05-039, and they can be used in areas with low headroom and hfwa-nhi-05-039 access.

The attendees will gain a general knowledge of the design, construction and performance fhwa-nhi-05-039 micropile foundation system.
