Abstract:

The construction technology, implement mechanism, reinforcement efficiency of implementing method of backfill of abutment back with horizontal flexible-reinforced grouting technology were studied by in-situ experimental research combining with laboratory study. The in-situ test results show that the backfill of abutment back reinforced by the new horizontal flexible reinforced grouting technology has enormous advantages including easy processed, effectiveness, development and utilization value. On the processing of the in-situ test many valuable construction parameters and experimental data were obtained; and a lot of material resource could be used for changing the design and construction parameters so as to perfect the construction technology of the new technology. At the same time, a new engineering solution for the prevention and treatment of bridgehead jump-driving was offered.

Key words: backfill of abutment back, soil-stone filler, horizontal flexible reinforced grouting, field test research, backfilling strengthening, construction technology
