Description

A kind of cleaning vehicle for alkali return treatment of parks and municipal roads

technical field

The invention belongs to the field of ecological restoration, and relates to a cleaning vehicle for alkali return treatment of parks and municipal roads.

Background technique

Alkali return phenomenon is a kind of disease phenomenon of geotechnical materials, which commonly exists in the construction and maintenance management of parks and municipal roads. Ordinary concrete is silicate. When it encounters air or moisture in the geotechnical materials, hydrolysis reaction occurs, and hydrogen and oxygen are generated. The roots combine with metal ions to form hydroxides with less solubility. When the temperature rises, the water vapor evaporates, and the hydroxides are taken out of the geotextile materials. As the water gradually evaporates, the hydroxides are continuously precipitated out of the concrete. On the cement surface, white crystals are formed.

The white patches formed by alkali return disease will have a great impact on the appearance of the pavement and seriously affect the landscape effect; at the same time, under the action of water loss and carbonization, the pavement is more prone to cracking, and the pavement is prone to loosening and falling off. Under the action, the capillary pores of the concrete are connected to the outside world, and the soluble alkaline substances continuously migrate from the capillary pores to the concrete surface, adding to the phenomenon of returning to alkali, causing the concrete to dissolve out corrosion, and greatly reducing the strength, hardness, impermeability and resistance of the pavement. freezing performance, resulting in a significant reduction in the service life of the road.
