Does anyone know how to install precast concrete sheet pile into the position? I am now planning a project with 8.0m deep basement in a reclamation area. Since the price of steel sheet pile gone up too fast, my budget estimation is totally off. So, if precast concrete sheet pile may be applied, my nighmare will be gone!!
A method, which is efficient for installing pre-cast concrete sheet piles, would be by vibratory action. The main problem is, if you need a high end bearing resistance, for which you would probably have to use impact hammer. I suggest that you contact any of the vibrator manufacturers in the Geo Market Guide, for instance: http://www.krupp-gft-tiefbautechnik.com/
I think that vibrating concrete sheet piles into reclaimed soil (probably sand) should not be a problem. You should try to get CPT data for prediction of driving resistance.
