Abstract:
The present invention provides a widening structure and a construction method for an existing subgrade embankment wall section near a river. A concrete base is poured along a side line of a widened subgrade, a prefabricated concrete barrier plate is provided on the base in the longitudinal direction of the subgrade, and a vertical rod and a pull rod for reinforcing the barrier plate are provided on the base; and a plurality of levels of steps are provided on a side slope of the existing subgrade, and foam light soil is filled between the barrier and the side slope of the subgrade. The barrier plate in the present invention has lower bearing requirements on a foundation, and causes little damage to an existing embankment when a side line of a widened subgrade is located on a side slope of the existing embankment; when the side line of the widened subgrade overlaps an existing embankment wall or is located in a river course, the existing embankment wall does not need to be dismantled, the existing embankment wall can be fully used, the treatment of a river course foundation is avoided, the construction investment can be reduced, and the stability of the existing embankment is guaranteed.
