Highway concrete guardrail heightening and reinforcing structure and method thereof
The invention discloses a highway concrete guardrail heightening and reinforcing structure and a method thereof.The structure is provided with a drill hole communicating a guardrail, a guardrail foundation and a road shoulder, a hollow steel pipe is arranged in the drill hole, a prefabricated concrete heightening piece is arranged at the upper end of the guardrail, and a preformed hole in butt joint with the upper end of the hollow steel pipe is formed in the prefabricated concrete heightening piece; the prefabricated concrete heightening piece is provided with a grouting hole, the grouting hole is communicated with the preformed hole, slurry filling layers are arranged in a gap between the drill hole and the hollow steel pipe and in the hollow steel pipe, and a side connecting structure is arranged between the guardrail and the prefabricated concrete heightening piece. According to the method, the old concrete guardrail can be reinforced while heightening is achieved, meanwhile, operation is convenient, and the transformation time is saved.
本发明公开了一种公路混凝土护栏加高加固结构及其方法，该结构设置连通护栏、护栏基础及路肩的钻孔，在钻孔内设有空心钢管，在护栏上端设有预制混凝土加高件，在预制混凝土加高件上设有与空心钢管上端对接的预留孔，在预制混凝土加高件上设有压浆孔，所述压浆孔与预留孔连通，在钻孔和空心钢管之间的空隙及空心钢管内均设有泥浆填充层，在护栏与预制混凝土加高件之间设有侧连接结构；本发明能加高的同时还能对旧的混凝土护栏进行加固，同时，便于操作和节省改造时间。
