Embodiment Construction
[0033] In order to better explain the present invention and facilitate understanding, the following describes the present invention in detail through specific embodiments in conjunction with the accompanying drawings.
[0034] It should be noted that all the directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the difference between components in a specific posture (as shown in the accompanying drawings). If the relative positional relationship, movement situation, etc. change, the directional indication will change accordingly.
[0035] In addition, in the present invention, descriptions involving "first", "second", etc. are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined with "first" and "second" may explicitly or implicitly include at...

The invention relates to the technical field of road construction, in particular to an expressway anti-collision wall maintaining and reinforcing method which comprises the steps of chiseling away that the loose concrete with the preset thickness on an anti-collision face of an anti-collision wall to form an anti-collision core face, and chiseling away the heightening blocks on the top face of theanti-collision wall to form a top core face; chiseling the head-on collision core surface and the top core surface; planting the steel bars on the head-on collision core surface and the top core surface to form a steel bar planting net; mounting a supporting template, pouring the head-on collision core surface and the top core surface, increasing the height and thickness of the anti-collision wall, and enabling the anti-collision wall to reach a preset shape and a preset size; and maintaining the pouring position of the anti-collision wall, and coating the anti-collision wall after the supporting formwork is dismounted. The foundation of an existing concrete anti-collision wall mostly extends to the position below a road surface and is more difficult to detach, so that the foundation is heightened and thickened on the basis of the existing anti-collision wall, and the structural size and the anti-collision performance of the anti-collision wall meet the requirements of the current specifications.
Description
Technical field [0001] The invention relates to the technical field of road construction, in particular to a method for repairing and strengthening an expressway collision wall. Background technique [0002] Nowadays, many expressways were built and put into use in the 1980s and 1990s. It has been more than 20 years. Due to the early construction of highways, the anti-collision performance of concrete anti-collision walls has declined due to the natural aging of concrete and pavement modification. The specific problems are: the concrete label (24.8) of the anti-collision wall is lower than the design label (25); the heightened block and the original structure have serious longitudinal cracks and lose their integrity; the structure size is too small and the reinforcement ratio is low. The safety of the anti-collision wall is insufficient; the steel bar is corroded and the concrete is cracked, and the durability of the anti-collision wall is insufficient. The traffic volume on the...
