A preparation device and method for cement-based crack grouting material for road bridges

Abstract

The invention relates to the technical field of grouting materials, in particular to a preparation method of cement-based crack grouting materials for road bridges, comprising a feed pipe, a weighing cylinder is arranged below the feed pipe, and the number of the weighing cylinders is Four and arranged in a circular array, the lower surface of the weighing cylinder is offset by a weighing platform, the surface of the weighing platform is fixedly connected with a display block, and the inner wall of the display block is fixedly connected with a display screen. A rotary motor is arranged below the table, the inner wall of the rotary motor is rotatably connected to a rotary rotor, and the surface of the rotary rotor is fixedly connected to a connecting rod. According to the properties of different raw materials, the present invention is convenient to adopt the method of heating up to obtain a certain raw material mixture in a sufficient and quantitative manner, and then prepare it into a grouting material product, so that the grouting material can fill the joints more completely, and the water blocking and reinforcement effects are better. Good, and the whole process is highly automated, saving time and effort, and saving labor costs.

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...

Problems solved by technology

[0004] The purpose of the present invention is to provide a preparation device and method for cement-based crack grouting material for road bridges, to solve the problem that in the existing grouting material preparation process proposed in the above-mentioned background technology, the quality cannot be obtained by direct mixing and stirring. High and well-integrated grouting material, so that the grouting material contains large particles of impurities, resulting in incomplete joint filling, or poor water blocking and reinforcement effects when the grouting material is filling the joints
