REVERSE CIRCULATION DRILLING (RCD) PILES
Owing to the soil profiles in most of Vietnam’s projected site, Reverse Circulation Drill Method is considered to be the most suitable and economical construction method for the pile construction. The advantage of this method includes the maintenance of required pile verticality, short construction time and lower budget, etc.
Since the groundwater table is possibly encountered during the pile construction, groundwater treatment becomes one of the most important factors for this construction to success and keeps the loss of poured concrete to a minimal.
Also, the bottom sludge of the pile is another important factor for determination of pile capacity and quality according to past experience and research. Therefore, both groundwater and bottom sludge must be carefully treated. And, Tung Feng Construction Engineering Vietnam Co., Ltd. has capabilities and confidences to overcome these challenges.
