Conventional technology

BACKGROUND ART A roadbed is a structure that directly supports a railway formed by embankment or excavation, and is also called a track substructure. Subgrades are connected to bridges and tunnels to form tracks. There are two basic types of subgrades, embankments and cuts, depending on topographical conditions, and they are usually called embankments and excavations. The function of a railway roadbed is to lay railway structures directly on the surface of the roadbed. The roadbed is thus the foundation of the railway, supporting not only the weight of the railway structure, ie the static loads, but also the dynamic loads that are transmitted through the railway when the train is running.
For foundation earthwork, it is necessary to drain water in advance and excavate and remove sludge and dirt.
Currently, construction companies generally clean garbage manually, which is very troublesome, and for garbage that cannot be easily cleaned, such as grass and tree roots, it takes a lot of human and material resources to find it. It is time consuming and very inconvenient.
