Embodiment Construction
[0022] The structure of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but it is not intended as a limitation of the present invention.
[0023] Such as figure 1 As shown, the present invention discloses an anti-skid structure for abutment straps. Specifically, the anti-skid structure for abutment straps includes an abutment 4, a strap 5, an anti-skid steel bar 1 and a metal sleeve 2; the metal sleeve 2 is arranged on In the strapping plate 5 , the lower part of the anti-skid steel bar 1 is located in the abutment 4 , the upper part of the anti-skid steel bar 1 is located in the metal sleeve 2 , and asphalt 3 is filled between the metal sleeve 2 and the anti-skid steel bar 1 .
[0024] In a preferred embodiment of the present invention, the length of the above-mentioned anti-skid steel bar 1 located in the butt plate 5 is shorter than the length of the anti-skid steel bar 1 located in the abutment 4...

The invention relates to the technical field of building construction, in particular to a bridge abutment bridging plate skid resistance structure and a construction method thereof. Part of a skid resistance steel bar is embedded in a bridge abutment, and the part, located above the bridge abutment, of the skid resistance steel bar is sleeved with a sleeve. The sleeve is filled with pitch joint sealing materials, and then the bridging plate construction technology is conducted above the bridge abutment. Since the sleeve is filled with the pitch joint sealing materials, stress buffering of thebridge abutment and the bridging plate is facilitated under the action of external force, stable transition of a bridge and a road bed is guaranteed, and the running comfort is improved. Since the bridge abutment and the bridging plate are connected through the skid resistance steel bar, the integrity of the bridge abutment and the bridging plate is improved. Meanwhile, since the method is simplein operation, raw material machining is easy to implement, and very high practicability is achieved.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to an anti-slip structure of an abutment lap slab and a construction method thereof. Background technique [0002] The abutment slab connects the subgrade and the bridge and ensures a smooth transition between the two. It is a structural form that is widely used at present. Under the action of automobile impact load, the longitudinal displacement of the strap (the longitudinal displacement refers to the displacement of the strap along the road direction) will directly affect the driving comfort. In the current technology, expansion joints are generally set between the abutment and the strap to relieve the impact of the strap on the abutment, but there is no corresponding anti-skid structure between the abutment and the strap, which is undesirable for those skilled in the art. arrived. Contents of the invention [0003] In view of the above existing problems, the pr...
