Zusammenfassung:The utility model relates to the field of dust falling during tunneling operation, in particular to a spraying dust falling device for a roadway, which can be used for isolating and falling dust of raised dust generated during operation of a tunneling machine. According to the technical scheme, the dust collection device comprises a dust-containing airflow purification device and a negative pressure dust collection device, wherein the dust-containing airflow purification device is communicated with the negative pressure dust collection device. The dust-containing airflow purification device comprises atomization nozzles, and the atomization nozzles are fixed to the wall of the roadway. The negative pressure dust suction device comprises dust suction ports, a filter and a storage cavity, the dust suction ports are formed in the wall of the roadway below the atomization nozzles, an inlet of the storage cavity is communicated with the dust suction ports, the filter is arranged at the outlet end of the storage ca
