An integrated construction train with double-layer stress-absorbing belts

Abstract

The invention belongs to the field of road engineering, and relates to a double-layer stress absorption band integrated construction train. The double-layer stress absorption band integrated construction train comprises a train body and a carriage which is dragged by the train body; a first stress absorption band preparation and pavement device, a second stress absorption band preparation and pavement device and a compacting device are arranged in the carriage in the axial direction of the carriage in sequence; a data acquisition and control device which is connected with the first stress absorption band preparation and pavement device and the second stress absorption band preparation and pavement device is also arranged in the carriage; the data acquisition and control device comprises a control box; a controller, and a heating control chip and a switch driver which are respectively connected with the controller are arranged in the control box. The double-layer stress absorption band integrated construction train has the advantages that the structure is simple, the design is reasonable, the use and operation are convenient, the use effect is good, the preparation and pavement of a double-layer stress absorption band can be completed conveniently and quickly, and the preparing and paving processes are easy to control.

Description

technical field [0001] The invention belongs to the field of road engineering, and relates to road engineering maintenance equipment, in particular to a double-layer stress-absorbing belt integrated construction train. Background technique [0002] The "white plus black" reconstruction technology refers to the technology of maintaining the integrity of the old pavement, taking measures such as grouting under the slab, partial replacement or repair, and then directly adding an asphalt overlay on the old cement concrete pavement. This method can make full use of the remaining structural strength of the old cement concrete pavement and reduce the overlay thickness. However, the problem of reflective cracks in the overlay layer faced by this technology has always been one of the difficult problems faced by the highway industry. The existence of reflective cracks not only destroys the overall strength of the pavement structure, but also causes the surface layer to gradually lose...

AI Technical Summary

Problems solved by technology

However, the problem of reflective cracks in the overlay layer faced by this technology has always been one of the problems faced by the highway industry.

The efficiency of this method is low, the material of the stress absorbing belt is scattered more, and the waste of material is serious

In addition, the brushing tool does not have heating equipment, and the material of the stress absorbing belt has a high viscosity, which gradually sticks to the brushing equipment during construction, which is extremely inconvenient to operate

The existing stress-absorbing belt paving equipment is only suitable for mechanized construction of a single-layer stress-absorbing belt, and cannot solve the problem of integrated construction of double-layer stress-absorbing belts, which seriously affects the integration of upper and lower layers of stress-absorbing materials, and the existing equipment It is difficult to ensure the thickness and flatness of the stress absorbing band
