Description

Technical Field

[0002] Roads and bridges are generally composed of several parts, such as roadbed, pavement, bridges, tunnel engineering and traffic engineering facilities. With the vigorous development of the transportation industry, the number of high-grade highways, mainly expressways and first-class highways, has increased year by year. my country's highway industry has begun to enter a new stage with the construction of high-grade highways as the focus. High-grade highways should pay special attention to the design of the line shape, maintain the continuity of the line shape, and make passengers feel safe and comfortable physically and psychologically.

[0003] Most municipal road bridges are made of cast cement. With the increase of bridge construction time and the increasing traffic volume, cement cast bridges will inevitably produce a small number of cracks. Therefore, the cracks in the bridges need to be reinforced. Bridge reinforcement generally refers to restoring or improving the bearing capacity of existing bridges by strengthening components and improving structural performance, so as to extend their service life and meet the requirements of modern transportation.

[0004] The existing bridge crack reinforcement work is generally carried out by grouting machines to inject glue or crack repair glue into the cracks until the entire gap is filled. If the glue injection is not strict, it needs to be supplemented. After the glue injection is completed, it is sealed. After it is completely cured, the bridge surface is cleaned and polished to restore the overall flatness of the bridge deck. If this bridge crack repair method is used, when grouting the cracks at the bottom of the bridge, because the cracks are cracked from bottom to top, the slurry cannot be fully filled in the cracks without any auxiliary reinforcement structure, which will cause the quality of the crack repair to be unqualified.
