[0002] At present, when heavy construction machinery passes through the culvert and underground drainage pipe position of the construction site, the water ditch is usually diverted, and the original water ditch is relocated to other positions, then the original culvert and drainage ditch can be abandoned, so that the heavy construction machinery can directly cross or stop on the existing drainage ditch and culvert. However, if the construction space is very limited, there is no space to relocate the culvert and drainage ditch, and the rainfall in this area is very large, which needs to be drained in time. At this time, the original drainage ditch and culvert need to be continued to be used, and the original designed drainage ditch and culvert cannot bear the load of heavy machinery. What measures should be taken to protect the existing drainage ditch and culvert to ensure smooth drainage and meet the requirements of heavy construction machinery walking and stopping becomes a technical problem that needs to be solved by the technical personnel in the field.
[0003] At present, when large machinery needs to cross the underground structure to be protected, the bridge structure principle is usually used to cross the underground structure to be protected by using a small bridge to ensure that the load of large machinery is not transmitted to the underground drainage structure.

However, the method of cast-in-place reinforced concrete needs a certain time to form the structure strength, and the structure cannot be reused, which is a one-time use structure, and the construction cost is significantly increased.
