Description
Technical Field
The utility model belongs to the technical field of novel abutment butt strap slip casting structure, concretely relates to novel abutment butt strap structure convenient to slip casting is consolidated.
Background
With the rapid development of national economy, highway engineering and bridge engineering in China are rapidly developed. Along with the increasing of the traffic volume of roads, the load of vehicles is aggravated, factors such as weather rainwater and the like cause damage and diseases to the connecting parts of certain roads and bridges, the comfort and traffic safety of driving are seriously influenced, the maintenance of the road pavement faces a severe test, particularly, the connecting parts of the roads and bridges, namely abutment butt straps, are common parts which are most prone to damage and diseases, the abutment butt straps can be continuously worsened under the action of load, the butt straps are caused to be empty and unevenly settled, further, the more serious bridge head jumping phenomenon is caused, and the safety and the comfort of the roads are greatly reduced.
The conventional treatment process is a butt strap grouting reinforcement technology, and the conventional abutment butt strap structure is directly provided with grouting holes for grouting, so that the practice shows that the structure is used, because butt strap void and abutment subgrade uneven settlement cause the butt strap void space to be an open space, the two sides of the butt strap are also open spaces, and grout overflows and is not easy to fill.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides a novel abutment attachment strap structure convenient to slip casting is consolidated, including road surface and bridgehead attachment strap structure, set up the bridge expansion joint between road surface and the bridgehead attachment strap structure, the middle part of bridgehead attachment strap structure sets up a plurality of injected holes, wherein, the position that the bridgehead attachment strap structure is located the edge sets up a plurality of high polymer banding holes.
Preferably, the aperture of the grouting hole is larger than that of the high polymer edge sealing hole, the aperture of the high polymer edge sealing hole is 16-20mm, the pitch of the high polymer edge sealing hole is about 1.0m, the pitch of the grouting hole is about 2.0m, the aperture of the grouting hole is 30-76mm, and the grouting hole is arranged in a quincunx shape.
In any of the above embodiments, it is preferable that the distribution density of the high polymer edge sealing holes is greater than the distribution density of the grouting holes.
In any of the above embodiments, preferably, the high polymer edge sealing holes are provided on the outer periphery of the grouting hole.
In any of the above solutions, it is preferable that the middle part of the bridge end access plate structure is provided with an exhaust hole.
In any of the above embodiments, preferably, the number of the vent holes is 1 to 2.
The utility model has the advantages that: the utility model provides a pair of novel abutment attachment strap structure convenient to slip casting is consolidated sets up a plurality of high polymer banding holes through the position that is located the edge at the bridgehead attachment strap structure, be convenient for pour into two ingredient high polymer materials (special resin and hardener) of injection through the high polymer banding hole into, take place chemical reaction after two kinds of materials mix, the volume expands rapidly and forms the foamy solid to reach bridgehead attachment strap structure bottom and fill the mesh of coming to nothing, make the cement thick liquid that pours into through the injected hole fully fill, it is not excessive.
