Description

Technical Field

[0001] This utility model relates to a slipform for constructing highway guardrails, belonging to the field of building construction technology. Background Art

[0002] The barriers separating the two lanes of a highway, depending on road conditions and geographical location, are sometimes flower beds and sometimes masonry retaining walls. Their main function is to prevent pedestrians, animals, or other unwanted objects from crossing the highway, and also to prevent headlights from the opposite highway from shining on drivers on this side, affecting nighttime safety. The retaining walls have certain height requirements, and steel cables must be placed inside to ensure the concrete has sufficient strength in the event of a vehicle impact. Chinese utility model patent CN202321773025.6 discloses a masonry retaining wall with a reinforcing mesh. The reinforcing mesh abuts against the retaining wall body, and the required concrete facing is processed on the mesh. The reinforcing mesh acts as a formwork for the concrete facing, thus allowing the exposed surface of the retaining wall to meet the requirements for hollow self-drilling anchor bolts, enabling rapid repair of the retaining wall body.

[0003] However, the inventors of this utility model have discovered the following problems with the existing technology: In the past, the construction of isolation walls was carried out manually, and steel cables had to be placed in real time during the construction process. This not only resulted in low work efficiency and high cost, but also extremely high labor intensity. Moreover, the isolation walls built were not flat enough, which affected the aesthetics. Therefore, improvements are needed. Summary of the Invention
