Problems solved by technology

[0002] With the development of science and technology, people's transportation is becoming more and more convenient, but the road subgrade may have cavities due to diseases. If the cavities are not treated in time, the road may collapse, leaving serious safety hazards for people. It can be filled by excavation. To solve this problem, but digging and filling is time-consuming and labor-intensive, and it takes a long time. Another filling method is to fill the cavity with rapid volume expansion after the chemical reaction of polymer materials, but it is difficult to accurately calculate the size of the underground cavity. out, making it difficult to determine the amount of polymer filling, affecting the use of this solution

Abstract

The invention discloses a method for repairing a road by accurately filling road base damages with high polymer. The method comprises the following steps: S1, detecting the position of a cavity below an air road through ultrasonic waves; S2, drilling through repair equipment according to the position of the cavity; S3, pre-setting a pressure intensity value for the repair equipment, introducing an isolating film into the cavity through the repair equipment, and charging gas into the isolating film through the repair equipment, so that the preset pressure intensity value is achieved in the isolating film; S4, discharging the gas in the isolating film and taking out the isolating film, and feeding the isolating film into the cavity through space regulating equipment; S5, calculating the volume of the cavity according to the amount of the gas charged into the isolating film, and grouting into the isolating film according to the volume of the cavity; and S6, regulating volume of space, occupied in the cavity, of the space regulating equipment according to the pressure on the space regulating equipment. The method can be used for simply, conveniently and quickly filling the cavity below the road with a proper amount of high polymer.

Description

technical field [0001] The invention relates to the field of road repair, in particular to a method for accurately filling high polymers at road base diseased places for road repair. Background technique [0002] With the development of science and technology, people's transportation is becoming more and more convenient, but the road subgrade may have cavities due to diseases. If the cavities are not treated in time, the road may collapse, leaving serious safety hazards for people. It can be filled by excavation. To solve this problem, but digging and filling is time-consuming and labor-intensive, and it takes a long time. Another filling method is to fill the cavity with rapid volume expansion after the chemical reaction of polymer materials, but it is difficult to accurately calculate the size of the underground cavity. out, making it difficult to determine the amount of polymer filling, affecting the use of this solution. Contents of the invention [0003] Based on the...
