Abstract

The invention discloses a size mixer. The size mixer comprises a tee pipe fitting, a grouting nozzle connected with the outlet of the tee pipe fitting, a first size input pipe connected with the first inlet of the tee pipe fitting, and a second size input pipe connected with the second inlet of the tee pipe fitting, the end of the first size input pipe which runs through the inner cavity of the tee pipe fitting is a size confluence point, and the size confluence point is located at the outlet of the tee pipe fitting or close to the outlet. The size mixer enables the size to combine uniformly, the size setting time can be regulated at any time, the fixed-point free grouting is realized, the leaking stoppage depth is free, the filling is compact, and the leaking stoppage is complete.

Description

technical field [0001] The invention relates to the technical field of chemical grouting equipment, in particular to a grout mixer. Background technique [0002] For the construction of urban tunnels with highly dense buildings, how to overcome the impact of groundwater seepage on construction, domestic and foreign experts have been constantly seeking new breakthroughs and exploring new construction methods and methods. At present, the commonly used grouting construction methods for plugging in China are mostly rotary spraying high-pressure grouting method, deep stirring grouting method, and static pressure grouting method. The actual construction in recent years has proved that the traditional grouting plugging method is difficult to meet the special timeliness requirements of plugging, the construction preparation time is long, and the water outlet point cannot be cured in a short time. [0003] Chemical grouting is a relatively advanced plugging construction method emerg...
