[0002] A dump truck, also known as a soil truck or a slag truck, does not refer to a specific type of vehicle, but rather a truck that is used to transport construction materials such as sand and stone. During the construction of a tunnel, it is necessary to open a passage through the middle of a mountain or other obstruction. During the excavation process, a large amount of dust particles will be generated as the depth increases. When other equipment is used to load soil or rock onto a dump truck and transport it out of the tunnel, the fluidity of the air will cause the dust particles to continue to spread and extend over a wide range, and dust reduction treatment will be required after the dump truck leaves the tunnel.
