[0002] Generally, some culverts are set up under the expressway to facilitate pedestrians or vehicles to pass through the expressway from below. Generally, the construction of culverts is carried out simultaneously with the construction of expressways. Generally, supporting piers need to be set up in the middle of the culverts. On the one hand, it supports the road surface of the expressway, and on the other hand, it is also to separate the lanes in different directions of the culvert. When constructing the piers in the middle of the culvert, the commonly used formwork structure is built to facilitate the subsequent concrete pouring.

[0003] During the construction of the culvert intermediate pier, it is necessary to continuously build formwork and load-bearing scaffolding according to the different positions of concrete pouring. Building formwork and load-bearing scaffolding will waste a lot of construction time, resulting in complicated culvert construction process and low culvert construction efficiency. The materials for building formwork and load-bearing scaffolding need to be moved around in the culvert, wasting a lot of manpower and material resources; the modularization degree of the formwork of the entire culvert is low, so a highly versatile formwork system is needed to shorten the construction period and save a lot of human resources.
