Abstract

The invention provides a grouting material pressure filter testing device and method. The device comprises a grouting module and a testing module. The grouting module provides grout for the testing module through a grouting pipeline. The testing module comprises a testing cylinder. A testing cylinder base is arranged at the bottom end of the testing cylinder. A sealing cover connected with a pressure gauge is arranged at the top end of the testing cylinder. A grouting pipe for being connected with the grouting pipeline is arranged on the side wall of the testing cylinder. A filling medium is distributed in the portion, below the grouting pipe, of the testing cylinder. The upper end and the lower end of the filling medium are provided with water filter stone. The grout is pressed into the testing module through the grouting module and infiltrates the filling medium in the testing module so that testing can be completed. The testing device is small in size, easy and convenient to operate, recyclable and capable of reducing testing cost.

Description

technical field [0001] The invention relates to a filter press test device for grouting materials, in particular to a filter press test device and a test method for studying the passive water separation of cement single liquid slurry under the action of grouting pressure. Background technique [0002] In recent years, with the rapid development of underground projects such as tunnels and mines in my country, water and mud inrush phenomena have occurred from time to time during the construction process. According to statistics, the frequency of water and mud inrush disasters ranks second among underground engineering accidents. The resulting economic losses and casualties rank first. [0003] Grouting is a very important technical means in the construction of underground projects and the handling of engineering disaster accidents. At present, some researches have been done on the water separation phenomenon of cement single slurry as the grouting material under the action of i...
