Type : Pile Drilling Machinery
Date of Release : 2012-11-13

The project provides electricity and heating for Sochi Winter Olympics and for surrounding cities. The plant is built in mountain. North of it is railway. West of it is sea.All the constructions adopt basic pile. The diameter of the pile ranges from 600mm, 800mm, 1000mm,1200mm to 1400mm. The depth of the pile ranges from 6m, 8m, 12m, 14m to 16m.SR150C rotary drilling rig,equipped with casing drive adapter and casing, works for the construction. Its auger bit diameter is 800m,and the depth is 1.5m. Full-casing construction method is adopted.Geological conditions: clay, sand, strongweathered layer and intermediate-weathered layer.

The underground water is resourceful, however, thanks to the casing, it cannot affect the construction. It only takes 2 to 6 hours to complete a borehole. The time for completing a borehole varies due to different depth and diameter.

Our rig has completed about 120 piles within one month for the project. No severe accident happens during construction. The rig performs extraordinarily, and no big problem has occurred. Even some little trouble occurred,it has been treated promptly.

The maintenance is performed well. The rig has completed its construction mission smoothly for customer. It has been working strictly accordance with construction speed schedule and it has created enormous profit for customer.
