This is really a drilling question so you might try a variety of drilling terms in the library catalog or databases. For example, trenchless construction, horizontal drilling, directional drilling , pipe ramming, or cut and cover might be useful terms.
The first database to try is the ASCE library. You can find this from the library website by going to the tab "Research by Subject" and choosing "Civil and Construction Engineering." The link to the ASCE database is under "Core Resources," along with others you might try.
An appropriate website to explore is the EPA.
