Description

Technical Field

[0001] The utility model relates to the technical field of grouting construction, in particular to an anti-clogging grouting pipe for grouting of a grouting machine. Background Art

[0002] During construction and road maintenance, soft soil, road subgrade, etc. are often reinforced. Grouting technology has been widely used as a relatively mature engineering technology. The basic principle of grouting is that the slurry is pressed into the cracks, pores or holes of the stratum or structure under pressure to improve its integrity and density.

[0003] During grouting, the PVC grouting pipe needs to be inserted into the foundation. However, since the foundation contains a large amount of sand and gravel, the sand and gravel rub against the outer wall of the PVC grouting pipe. The sand and gravel can easily enter the interior from the grouting hole and then block around the grouting hole, affecting the grouting work. Utility Model Content
