Device and method for quickly repairing road base disease

Abstract

The invention discloses a rapid repairing device and method for diseases of a roadbase. The rapid repairing device comprises a vehicle body, a drilling mechanism, an inflation mechanism, a water injection mechanism, a material adding mechanism and a sealing mechanism. A thin film is tightly attached to the bottom surface and lateral surface of a seam through the inflation mechanism. The water injection mechanism is used for injecting water into a space formed by the thin film, then the volume of the seam is measured, a corresponding quantity of repairing materials are injected according to the volume of the seam, and expansion of the repairing materials is limited through the sealing mechanism. In this way, the proper number of repairing materials are added and expand to a proper volume, so that the best performance is guaranteed. The use amount of the repairing materials for road repairing is small in error, waste is avoided, resources are saved, and the road seam is convenient to repair and good in repairing effect.

Description

technical field [0001] The invention relates to the technical field of road surface repair, in particular to a device and method for quickly repairing road base disease. Background technique [0002] Concrete pavement is one of the main structural forms of highways, bridges, and urban roads. Under the action of traffic loads and natural factors, cracks, potholes, edge collapse, and wrong platforms often appear on the pavement. In order to ensure road safety Unimpeded, it is necessary to repair the cracks in the road in time. [0003] Polymer grouting technology is a rapid foundation reinforcement technology developed in the 1970s. This technology injects high polymer materials into the foundation, and utilizes the characteristics of rapid volume expansion and solidification of high polymer materials after a chemical reaction to achieve the purpose of strengthening the foundation, filling voids or lifting the floor. At present, polymer grouting technology is mainly used in ...

Problems solved by technology

[0004] The density and properties of high polymer materials are constantly changing after expansion. The expanded density determines its strength and other properties. High polymer materials can expand about 20 times. The smaller the external pressure, the greater the volume change. However, high polymer materials When the material expands to a certain volume, the performance is the best. If the volume expansion is too small or too large, the performance will decrease. Therefore, it is necessary to control its volume change.

[0005] Due to the complexity of the crack situation, it is impossible to add an appropriate amount of polymer material according to the actual volume of the crack. If the polymer material is added too much or too little, the expansion volume will change too much or too small. Moreover, the road in the prior art When repairing, most of the materials are allowed to expand arbitrarily, and the volume change cannot be controlled, resulting in unsatisfactory performance, which needs further improvement
