Technical Field

[0002] Road and bridge construction refers to road construction and bridge construction, including the survey, measurement, design, construction, maintenance and management of roads and bridges. In the specific construction process of roads and bridges, it is necessary to set up retaining structures on the side to reinforce the side and prevent the side materials from falling. It can be an erected guardrail or a cast square retaining frame. In order to adapt to the side structure of road and bridge construction, a more targeted cast retaining structure is generally used.
[0003] The cast retaining structure generally includes a base plate and four side baffles forming a square inner cavity. When in use, the base plate is installed on the side of the road and bridge construction site to fix the position of the retaining structure, and the four side baffles are fixed on the base plate by side plug-in. At the same time, the support is usually completed by plug-in between two adjacent side baffles. However, in actual use and subsequent pouring, due to the lack of a fixed structure between the top ends of the four side baffles, the top surface supporting strength of the four side baffles is poor. As concrete is continuously poured, the four side baffles are prone to break through the restrictions of the bottom and side plug-in structures and there is a risk of outward deflection or offset, resulting in gaps or notches between the four side baffles, causing concrete leakage, reducing the quality of the retaining structure, and in severe cases, causing the retaining structure to fail.
