Description
Technical Field
The utility model relates to a bridge reinforcement field especially relates to a counterfort formula truss reinforced structure of abutment.
Background
The pile type bridge abutment is convenient to construct, clear in stress, simple in structure treatment and relatively low in manufacturing cost, and becomes a main bridge abutment form of a small bridge. However, engineering practice shows that although the pile-column type abutment has many advantages, the application of the pile-column type abutment is limited by the adverse factors of small thrust rigidity, easy inclination and pile cracking, low bearing capacity and the like. Many existing pile column type abutment, because the slip of filling soil behind the platform, embankment increase height, vehicle impact effect, construction sequence are improper etc. cause during construction or use, the hoop crack or slope appear in the pile body.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to prior art's defect and not enough, provide a counterfort truss reinforced structure of abutment, this structure provides a construction simply, and strong adaptability's stake formula abutment reinforced structure can improve plateau abutment anti-pushing rigidity, bearing capacity and stability by a wide margin.
In order to achieve the above object, the utility model adopts the following technical scheme: a buttress type truss reinforcing structure of an abutment comprises a front abutment protection slope, an original abutment foundation pile, an abutment cap, a longitudinal connecting beam, a newly-added foundation pile, a transverse connecting beam and an inclined strut; the platform front slope protection is an inclined slope protection structure filled with earth under an original bridge, original platform foundation piles are built in the platform front slope protection, and platform caps are built on the top surfaces of the original platform foundation piles; the original abutment foundation pile is built with a longitudinal connecting beam towards one side of the river center under the riverbed, and the longitudinal connecting beam is perpendicular to the original abutment foundation pile and is connected with the original abutment foundation pile through an anchor bar; newly-added foundation piles are built on the end face of one end, facing the center of the river, of the longitudinal connecting beam, the newly-added foundation piles are of reinforced concrete cylindrical structures with the size smaller than that of the original abutment foundation piles, and the bottom ends of the newly-added foundation piles are buried in the riverbed; the end part of the top end of the newly added foundation pile is provided with a square through hole, a transverse connecting beam penetrates through the through hole, penetrates through all the newly added foundation piles and is connected with the newly added foundation piles through anchor bars; the new foundation pile top end face is built with the bracing, and this bracing parallels with the bank protection before the platform, and the bracing other end is connected to former abutment foundation pile side through the anchor bar.
Preferably, the distance between the original abutment foundation pile and the newly added foundation pile is 3-4 m.
The utility model has the advantages that: the pile column type bridge abutment reinforcing structure is simple in construction and high in adaptability, and can greatly improve the anti-thrust rigidity, bearing capacity and stability of the bridge abutment.
