Comprehensive treatment and restoration structure and construction method of embankment base disease

Abstract

The invention relates to a comprehensive treatment and repair structure for diseases of an embankment base layer. The comprehensive treatment and repair structure comprises an embankment V-shaped groove repair structure body, an embankment step-type open groove repair structure body and an embankment base layer disengaging control grouting repair structure body. The embankment V-shaped groove repair structure body is composed of hinged V-shaped unit type rib frames. The hinged V-shaped unit type rib frames are longitudinally arranged along the road surface. The lower portions of the hinged V-shaped unit type rib frames are connected together through connecting rib bottom plates. Net-shaped rib sheets are bound on the hinged V-shaped unit type rib frames, and vertical prestress middle ribsare arranged on the hinged V-shaped unit type rib frames. Bonding layers and anti-cracking reinforcing layers are laid on the upper portions of the hinged V-shaped unit type rib frames. The comprehensive treatment and repair structure has the beneficial effects that unit type rib frame embankment V-shaped grooves are formed in the surface layer of the road surface, local all-deep milling is replaced, an embankment V-shaped groove skeleton is composed of the hinged V-shaped unit type rib frames, tooth nails on the hinged V-shaped unit type rib frames are deeply inserted into a lower surface layer, thus meshing force of the embankment V-shaped groove skeleton is increased, stress concentration at the top end of a crack is eliminated, and the crack is prevented from continuing to develop upwards.

Description

technical field [0001] The invention relates to a structure and a construction method for comprehensive treatment and repair of base layer diseases of embankments, and is mainly suitable for repairing base layer diseases of high-grade asphalt roads. Background technique [0002] Asphalt concrete pavement has good mechanical properties, good durability and driving comfort, and is suitable for the passage of various vehicles, so it is widely used in highway construction. However, due to the differences in the asphalt material itself and the design and construction level, some diseases often appear on the asphalt pavement. The emergence of these diseases has seriously affected the performance of expressways, increased road maintenance costs, and damaged the image of the industry. Therefore, it is necessary to analyze the causes of diseases and effectively prevent and treat them. [0003] The asphalt pavement is exposed to the atmosphere for a long time and bears the load of ve...

Problems solved by technology

[0006] (3) In the dry season, the road surface is dusty and wears heavily, which easily affects the driving sight and pollutes the surrounding environment

[0007] In view of this, in order to improve the construction quality of the comprehensive treatment and restoration of the grass-roots disease of grade highways, and improve the traditional lightweight embankment’s insufficient compressive capacity and failure to meet the traffic requirements, it is urgent to invent a simple and effective structure and construction method for the comprehensive treatment and restoration of the grass-roots disease of the embankment. Improving Construction Quality and Construction Efficiency of Lightweight Embankment
