Geopolymer grouting construction process and equipment for repairing expressway

Abstract

The invention discloses a geopolymer grouting construction process and equipment for repairing expressway. The geopolymer grouting construction process comprises the steps that the position, the shape and the size of a cavity below an expressway are detected through ultrasonic waves, the number and the positions of drill holes are determined according to the detected position, the shape and the size of the cavity, and the geopolymer grouting construction equipment is constructed according to the number and the positions of the drill holes, holes are formed in a surface layer through a drilling machine to determine hole positions needing to be grouted, sundries and gaps in the holes are cleaned up through a hole cleaning device, grouting pipes are inserted into preset positions in the holes, geopolymer grouting is conducted through a grouting machine, and therefore grouting is completed. Ultrasonic waves are adopted for detecting the expressway, the position, the shape and the size of a cavity below the expressway can be effectively detected, the number and the position of drilled holes can be accurately determined through the position, the shape and the size of the cavity, meanwhile, sundries and gaps in the holes can be effectively cleaned away by sweeping the interiors of the holes after drilling, and therefore, grout can be well diffused in the hole, and the grouting effect is improved.

Description

technical field [0001] The invention relates to the technical field of road repair and maintenance, in particular to a geopolymer grouting construction process and equipment for repairing high-speed roads. Background technique [0002] At present, China's expressways are in a stage of rapid development. Most of the expressways that have been built and are under construction are asphalt pavement, and the base is basically a semi-rigid base stabilized by cement and lime. For the construction of the roadbed, due to funding, The impact of various factors such as the construction period can only be dealt with in a simple way: such as shallow replacement, cement and lime treatment, and dynamic compaction. Due to the influence of conditions, some expressways have different degrees of disease. These diseases can easily lead to the generation of cavities under the pavement, which seriously affects the performance of the pavement. In order to ensure the safety of expressways, it is ge...
