Stress absorption band paving equipment applicable to maintenance of cement concrete pavement

Abstract

The invention provides stress absorption band paving equipment applicable to maintenance of a cement concrete pavement. The equipment comprises a traction control part, an accommodating part and a fiber cloth paving part, wherein the traction control part comprises a hand rail, a first handbrake, a second handbrake, a first guy cable, a second guy cable and rolling wheels; the accommodating part comprises a first accommodating bin and a second accommodating bin; the fiber cloth paving part comprises a fiber cloth bracket and a leveling rod. The equipment fully considers the structural characteristic, the material characteristic and the construction convenience of a stress absorption band. A temperature controller is adopted to control a heater to heat the accommodating bins to ensure that the binding material of the stress absorption band is kept at a proper construction temperature. The equipment is moved under the assistance of the rolling wheels. The equipment has excellent practicability for treatment of cracks when being used for additionally paving bituminous concrete on an old cement concrete pavement, can effectively relieve the problem of crack reflection of a composite pavement and ensures the long service life of the composite pavement.

Description

technical field [0001] The invention belongs to the field of road engineering, and relates to road engineering maintenance equipment, in particular to a stress absorption belt paving equipment suitable for cement concrete road surface maintenance. Background technique [0002] my country's high-grade highways mainly use two types of pavement structures: asphalt concrete and cement concrete. In recent years, the price of cement and steel has continued to slump, causing cement concrete pavement to gradually attract the attention of builders, especially in the middle traffic section, cement concrete has become the first choice for design and construction. As a considerable part of the cement concrete pavement has approached or exceeded the design period, although some have not reached the design period, due to the sharp increase in traffic volume, the increasingly heavy vehicle axle load, design, construction and other reasons, the road surface is damaged. The quality of use h...

AI Technical Summary

Problems solved by technology

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
