Preparation method of cement-based crack grouting material for roads and bridges

Abstract

The invention relates to the technical field of grouting materials, in particular to a preparation method of a cement-based crack grouting material for roads and bridges. The preparation method comprises a feeding pipe, four weighing cylinders are arranged below the feeding pipe and are arranged in a circumferential array, the lower surfaces of the weighing cylinders abut against a weighing table, a display block is fixedly connected to the surface of the weighing table, a display screen is fixedly connected to the inner wall of the display block, a rotating motor is arranged below the weighing table, a rotating machine rotor is rotatably connected to the inner wall of the rotating motor, and a connecting rod is fixedly connected to the surface of the rotating machine rotor. According to different raw material properties, a certain raw material mixture is sufficiently and quantitatively obtained in a temperature rising and heating mode, then a grouting material product is prepared, joint filling of grouting materials is more complete, the water plugging and reinforcing effects are better, the automation degree of the whole process is high, time and labor are saved, and the labor cost is saved.

Description

technical field [0001] The invention relates to the technical field of grouting materials, in particular to a preparation method of cement-based cracking grouting materials for roads and bridges. Background technique [0002] The grouting material is the main substance that fills and consolidates the fractures and pores in the formation. It is the key to achieve water blocking or reinforcement. The grouting material can be divided into granular grout, chemical grout and fine mineral grout. [0003] In the existing grouting material preparation process, the method of directly mixing and stirring by adding various raw materials in sequence is often used. Due to the different properties of each raw material, the method of direct mixing and stirring cannot obtain high-quality and well-integrated grouting materials. For slurry, some raw material ratios are not well thought out, and sufficient and quantitative chemical reactions cannot be obtained, so that the grouting material co...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of preparation method of cement-based crack grouting material for road and bridge, in order to solve the existing grouting material preparation process that proposes in the above-mentioned background technology, can not obtain higher quality with the mode of direct mixing and stirring, The fusion of better grouting materials will make the grouting materials contain large particles of impurities, resulting in incomplete filling of the grouting materials, or poor water blocking and reinforcement effects when filling the joints.
