YS- 1 Automatic spraying and atomizing maintenance equipment for precast box girder Product Description: This automatic spraying and maintenance equipment is independently developed according to the needs of users and Jianyi. Combined with the characteristics of precast box girder, the automatic spraying system realizes the automatic spraying and atomization maintenance of precast box girder by assembling control system and adding walking track, realizes all-round shape preservation, improves the maintenance quality and efficiency, and ensures the concrete strength of precast box girder. The device solves the problems of excessive or insufficient water consumption and low maintenance efficiency of the existing manual sprinkler maintenance. Instead, it automatically supplies water to the automatic water spraying reservoir through the water supply pipeline pre-planned and designed in the beam storage area, turns on the control switch, and automatically runs on the walking track, so that the sprayed gaseous water mist can achieve the purpose of precast box girder maintenance. Since the development and application of box girder maintenance equipment, the following characteristics have been highlighted: 1. Good maintenance effect: the automatic sprinkler system sprays gaseous water mist, which can achieve the following purposes. From water supply to completion, the sprinkler system basically realizes the automatic control of the process. 2. Greatly reduce the labor intensity: according to the calculation of precast box girder 1.5 holes /d and beam body maintenance period 10d, at least 15 people are needed, while automatic spraying only needs special personnel to switch on and off, properly supply water, track the equipment and do a good job in daily maintenance. 3. Water conservation: the project pays attention to recycling water to protect the environment, rationally uses water resources and saves water, so as to achieve the purpose of recycling water to protect the environment.
