Description

Digestion method of quicklime on pavement base

Technical Field

The invention relates to the technical field of quicklime digestion, in particular to a digestion method of quicklime on a pavement base.

Background

With the continuous development of infrastructure, road construction in highway engineering and municipal engineering is widely applied, and particularly, the construction field of environment-friendly products is more concerned by people in all circles. The two-ash soil adopted by the pavement base is a base mixture formed by mixing plain soil, fly ash and lime according to a certain mixing ratio. Although the strength of the two-ash soil cannot achieve ideal effect within seven days in high-temperature seasons, the later effect is more obvious. And the integrity is good, quality hidden troubles such as cracks are not easy to appear, the water stability can exceed that of common base materials, the low-temperature resistance is strong, the construction is simple and convenient, and a special mixing station is not required.

In the construction of the lime-soil, the construction process is as follows: preparing a lower bearing layer, construction lofting, transporting, paving and leveling soil, primarily pressing, transporting, paving fly ash, stabilizing the fly ash, surface lime (partitioning), mixing and sprinkling water, shaping, rolling, preserving health, and self-checking and accepting.

Before construction, the quicklime in the mixture is digested 7-10 days in advance and can be used after digestion. At present, concentrated spreading is adopted, and manual spraying is adopted for digestion. The quality is not over-closed when the device is used due to the fact that the water quantity is not controlled uniformly and the digestion is not in place, so that the construction quality of the two-ash soil base layer is directly influenced, and serious construction problems such as rework are caused.

s5, when much rainwater is collected, the floating ball automatically rises, the floating ball is provided with scales with obvious marks, the volume of the water bin can be observed below, the floating ball rises when the water amount is large, the floating ball flows to the middle water bin through the communicating water pipe, and the water in the middle water bin enters the water collecting bin in the center of the bin along the sewer pipe;

s6, when the water quantity in the water bin of the water shed is less than the communicated water pipe, the floating ball sinks, the water quantity is proved to be less than the slaked lime in the lower bin, the warning mark appears in the index, and the water pump and the water pipe are adopted to pump the water into the water bin above the water shed.

(III) advantageous effects

The invention provides a method for digesting quicklime of a pavement base. The method has the following beneficial effects: this method of dispelling of quick lime of road surface basic unit adopts rainwater to concentrate collection, the rational design of feed bin and sump, the end that sprays paint of sump lower extreme can be taken out by the manual work or the fixed spraying, dispels experimental required water yield through quick lime through adopting upper portion sump capacity and disposes feed bin water sump volume, and reasonable control mix proportion makes quick lime dispel the quality and has obtained the guarantee. Through utilizing the rainwater environmental protection more, save the water resource, adopt the sump to also play, prevent the risk that the lime of living is drenched by the rain.
