Construction method for cement gypsum composite stable steel slag base layer

Abstract

The invention discloses a construction method for a cement gypsum composite stable steel slag base layer. The construction method comprises the steps of construction preparation, construction lofting, centralized mixing of a mixture, mixture transportation, mixture paving by a paver, mixture compaction forming, quality inspection, watering maintenance, traffic control, handover inspection and the like. The invention also discloses a paver which comprises a paving mechanism, a measuring mechanism, a cutting mechanism and a cleaning mechanism; and the measuring mechanism is arranged at the rear end of the paving mechanism, the cutting mechanism is arranged at the rear end of the measuring mechanism, and the cleaning mechanism is arranged at the front end of the paving mechanism. According to the paver, transverse joint treatment is facilitated, follow-up connection is facilitated, the paving thickness can be rapidly measured, impurities on a road surface can be cleaned, and the road surface can be kept wet. The desulfurized gypsum and the steel slag are solid wastes of iron and steel enterprises, environmental pollution caused by the solid wastes of the enterprises is reduced, natural environment damage caused by collection of highway construction aggregates is reduced, and the method is more ecological and environment-friendly compared with a traditional process and has social and economic benefits.

Description

technical field [0001] The invention relates to the technical field of road base construction. Specifically, it is a cement gypsum composite stabilized steel slag base construction method. Background technique [0002] In recent years, with the implementation of my country's sustainable development strategy, people's awareness of environmental protection has increased, and the government has increasingly strengthened the supervision of the disorderly mining of natural sand and gravel. The contradiction between the supply and demand of natural aggregates used in road construction has become increasingly prominent. In view of the above-mentioned increasingly prominent problems of resource shortage and environmental damage, it is imperative to carry out in-depth and systematic research on the key technologies of using bulk industrial solid waste as road construction materials, and realize the industrialization of related technologies. As a road engineering construction enterp...

AI Technical Summary

Problems solved by technology

At present, a large amount of solid waste such as desulfurized gypsum and steel slag produced by iron and steel enterprises has not been effectively utilized, causing serious pollution to the environment and a serious waste of resources

At present, most of the aggregates needed in the road construction process are still collected from the natural environment, which further causes the destruction of the natural environment and the consumption of natural resources.

[0003] In addition, when the road is being constructed, it cannot be interrupted at will. When the paver is shut down due to failure or other reasons, it is often necess
