During the construction of the Road Noise Barrier foundation, it is necessary to confirm the hole position before the construction. The hole position is laid out from the bridge and the culvert side to the side. If there is a heterogeneous section (a section where the sound barrier foundation and other structures conflict), Take measures to avoid existing structures. In rainy days, it is prohibited to dig piles and open holes. If water is found in Road Noise Barrier pile holes, water pumps should be used to drain them in time to prevent accumulated water from being introduced into the hole wall to collapse. The bottom of the pile foundation should be tamped before pouring concrete; the bottom of the enlarged foundation should be laid with a gravel cushion before pouring concrete.
The foundation construction of the Road Noise Barrier should be carried out without affecting the safety of the construction. In order to reduce the disturbance to the ground, try to avoid over-excavation as much as possible, and the over-excavated part should be filled with concrete with the same mark. The pouring of exposed concrete components must be shaped by formwork, and the poured concrete must be vibrated and compacted.
The embedded parts of the Road Noise Barrier shall be installed first when the continuous beam is poured. The installation of the embedded parts must be accurate, and the position of the installation bolts and the elevation of the embedded parts shall not exceed 5mm. The welding and lap joint of the steel bars shall comply with the "Concrete Structure Design Specification" GB50010-2011 requirements. The concrete should be used up before the initial setting, and the hard concrete shall not be used continuously. After the exposed foundation is demolished, the surface should be repaired with M10 cement slurry. Antifreeze should be added to concrete during winter construction.
