Abstract

The invention discloses a double-liquid-wall post-grouting device which includes a first grout preparation device, a second grout preparation device, a first pump, a second pump, a backfill grouting pipe and a first controller; the first grout preparation device is used for preparing first grout and is in communication with the backfill grouting pipe through the first pump; the second grout preparation device is used for preparing second grout and is in communication with the backfill grouting pipe through the second pump; the backfill grouting pipe is used for mixing the first grout and the second grout; and the first pump, the second pump and a shield tunneling machine are connected to the first controller, and the first controller is used for controlling the working rate of the first pump, the working rate of the second pump and the advancing rate of the shield tunneling machine. The double-liquid-wall post-grouting device provides the grout fluidity and the grouting efficiency.

Description

technical field [0001] The invention relates to the field of automatic grouting, in particular to a double liquid wall back grouting equipment. Background technique [0002] In recent years, there have been more and more subway construction projects, and most of the subway construction needs to be deployed in the lower part of the ground. However, the problem of chassis subsidence will be encountered during the construction process; in the prior art, for the chassis subsidence problem, the construction process uses After single liquid wall grouting, the chassis gap is filled through wall thickness grouting to prevent chassis settlement; however, the grouting efficiency is seriously affected due to the poor fluidity of the generated grout. [0003] Based on the above problems, in order to solve the problem of poor fluidity of the slurry in the prior art, in the prior art, various additives are mixed into the slurry, but at the same time when the additives are mixed, the overa...
