Description

Technical Field

[0001] The utility model relates to the technical field of railway grouting tools, and more specifically, to a portable grouting connection device for railway operations. Background Technique

[0002] The grouting method is to evenly inject the slurry with gelation ability into the voids, cracks and cavities in the soil layer by means of pressure or electrochemistry principle. The slurry fills, penetrates and extrudes to cement the originally loose and broken rock stratum into a whole. By the combined action of the slurry and the soil body, rock, etc., the physical and mechanical properties of the rock stratum are improved, thus forming a structure with new structure, high strength, high waterproof performance and good chemical stability. Grouting construction is also often carried out in the field of railway operations.

[0003] The following problems exist in the prior art:

[0004] In the prior art, the connection device for grouting operation is generally of an integrated structure and cannot be disassembled and assembled. Therefore, it is not convenient for people to carry, and its portability in use is relatively low. Moreover, the grouting pressure cannot be seen during use, and it cannot be quickly stopped when problems occur in the grouting operation. Therefore, its limitations in use are relatively large.
