INSTALLATION OF A PIPE-TYPE FOUNDATION FOR BRIDGE PIER
SOORUZHENIE STOLBCHATOGO FUNDAMENTA MOSTOVOI OPORY
During the construction of the foundation of a large railroad bridge on one of the northern rivers the builders encountered a series of difficulties connected to the construction of boreholes of 1.6 diameter in the rock base of the casings. In the river bed the rock type had a sloping surface, making the process of drilling the boreholes difficult, because in the gaps between the blade of the small and the surface of the rock the loose soil flowed in intensively during drilling. The foundation was projected as lying upon thirteen pipe castings. The most effective method for the construction of the boreholes in the base of the casings, in the presence of loose pressuring of the blade of the casing on the rock and the intensive flowing in of sand into the borehole, was the application of a metallic tube in conjunction with the concrete lock of the pipe. Boreholes were drilled by these means in the foundations of all remaining casings.
