Abstract

The invention relates to the field of slurry detection, and discloses a shield tunnel synchronous grouting slurry performance detection device and a detection method thereof. The detection device is avolumetric flask. The volumetric flask comprises a flask body, a flask opening and a flask plug, and the flask body is divided into an upper flask body and a lower flask body. Volume scale marks andvolume scale values are marked on the surface of the upper bottle body, the length of the upper bottle body is larger than that of the lower bottle body, the cross section area of the lower bottle body is larger than that of the upper bottle body, and the volume of the lower bottle body is larger than that of the upper bottle body. The self-made special volumetric flask for slurry detection can rapidly and effectively detect the density, decantation rate, calculus rate and consolidation shrinkage rate of synchronous grouting slurry, and improves the precision and speed of slurry performance detection.

Description

technical field [0001] The invention relates to the field of grout detection, in particular to a detection device and a detection method for synchronous grouting performance of a shield tunnel. Background technique [0002] The shield method is the main construction method used in the construction of underwater tunnels and underground tunnels. The synchronous grouting technology behind the shield segments is a key technology in shield tunnel construction. During the construction process of tunnel excavation using the shield method, it is necessary to grout the back of the segment to fill the building gap. The grouting method behind the segment can be synchronous grouting or instant grouting. In the unstabilized ground, Synchronous grouting must be adopted in order to ensure the amount of grouting under normal grouting pressure, fill building gaps, prevent the ground from moving towards the tunnel, and reduce or control the surface settlement caused by the release of ground ...
