The application provides an environment-friendly watering device for a road green belt, which is arranged in a shrubbery of a flower bed. The environment-friendly watering device comprises a lamp post, two baffles, two drip irrigation sprinkling mechanisms and a house type support base. The lamp post is vertically arranged in the flower bed, and two house type support bases are symmetrically arranged on two sides of the lamp post. The drip irrigation sprinkling mechanism is connected with the house type support base in linkage, and the chute extends to the lamp post along the arc direction of the house type support base. The environment-friendly watering device for the road green belt is matched with the lamp post, the two baffles, the two drip irrigation sprinkling mechanisms and the house type support base. The environment-friendly watering device can realize irrigation by using a drip irrigation mode through laying a water pipe in the shrubbery. Water resource is greatly saved, and in order to facilitate the requirement of road dust suppression and dust reduction, the water pipe can be climbed to the lamp post to realize high place spraying, which greatly facilitates the use of personnel.

This invention relates to the field of road dust suppression technology, specifically to a bio-based dust suppressant that can be used for road reinforcement. Based on 100% solid content, it contains the following components in the following weight ratio: 100 parts xylose mother liquor and 3-50 parts polyamine crosslinking agent; wherein the xylose mother liquor contains 20%-70% solids by weight, with the remainder being water; wherein the solids contain ≥50% reducing sugars by weight, including D-xylose, L-arabinose, D-glucose, and D-galactose, and the xylose content in the solids is ≥20%. The dust suppressant obtained by this invention uses a large amount of waste xylose mother liquor, a byproduct of the sugar industry. This product is a renewable resource and a low-carbon renewable product. Furthermore, the dust suppressant obtained by this invention not only has dust suppression function but also good compressive strength and water resistance, and can be used as a soil stabilizer. Applying the dust suppressant of this invention to roads can produce a pavement system with excellent overall performance.

The application relates to a road sweeping optimization method, system, device and medium based on road dust dynamic prediction data. The method comprises the following steps: constructing a sweeping effect attenuation parameter set according to road historical operation data; constructing a natural evolution benchmark model according to real-time monitoring data to generate a natural evolution parameter set; coupling the sweeping effect attenuation parameter and the natural evolution parameter to construct a state space model; and solving a future prediction time domain sweeping operation scheme based on the coupling model in combination with a road sweeping optimization target and a road sweeping constraint condition. The method can realize the transition from passive response to current pollution to active prediction of future evolution, and effectively solve the technical problems of blind selection of sweeping time and low resource utilization efficiency caused by the mutual separation of prediction and decision in the traditional method.

This utility model discloses a road dust monitoring device, relating to the field of road dust monitoring technology. The device includes a housing, a data acquisition and monitoring component, and a display panel. The data acquisition and monitoring component includes a power distribution processor, a data acquisition and transmission module, and a particle acquisition and monitoring module housed inside the housing. The particle acquisition and monitoring module is horizontally connected to the middle of the housing's interior. One side of the data acquisition and transmission module is connected to the inner wall of the housing, and the other side is mounted on the particle acquisition and monitoring module. The power distribution processor is electrically connected to both the data acquisition and transmission module and the particle acquisition and monitoring module. The display panel is embedded in the upper front of the housing and is electrically connected to the data acquisition and transmission module. This device can automatically and quickly monitor road dust in real time during normal vehicle operation, calculate the road dust load on different road sections, and improve monitoring efficiency and data accuracy.

This invention belongs to the field of road dust control technology. It relates to a method for determining the surface water retention of open-pit mine transport roads, comprising the following steps: First, under laboratory conditions, basic data on the surface water content of the transport road and different environmental parameters are obtained, establishing basic data on the relationships between "water content-temperature-time," "water content-humidity-time," and "water content-wind speed-time." Second, using the basic data established in the first step, the surface water retention of the transport road at any cumulative time is calculated, thereby determining whether to spray water onto the road surface. This invention, by establishing basic data on the relationships between "water content-temperature-time," "water content-humidity-time," and "water content-wind speed-time," enables real-time calculation of the surface water retention of transport roads after spraying clean water or dust suppressants based on changes in meteorological parameters. This provides data support for intelligent decision-making regarding the timing of spraying transport roads, improves dust suppression efficiency, and saves water resources.
