Problems solved by technology

[0002] In the mine curtain grouting project, in order to monitor the grouting pressure, a pressure gauge is often used, but in the deep hole grouting, due to the high grouting pressure, the maximum can reach more than 10MPa, which is easy to cause damage to the pressure gauge, how to avoid it Damage to the core components of the pressure gauge is directly related to the quality and efficiency of grouting construction
The grouting part of the curtain grouting part of the mine has a large amount of grout suction per drilling section, and the grouting lasts for a long time. Under the action of high pressure for a long time, the pressure gauge will inevitably be damaged, resulting in inaccurate pressure records, which will affect the construction quality and efficiency.

Abstract

The invention relates to a slip casting pressure gauge pedestal device comprising a pedestal body. The pedestal body is provided with a first side and a second side, which are in an opposite arrangement. The pedestal body is provided with a first chamber transversely penetrating the first side and the second side of the pedestal body. The first chamber is provided with a first opening facing the direction, which is the same as the direction of the pedestal body, and a second opening facing the direction, which is the same as the direction of the pedestal body. The upper end of the pedestal body is provided with a second chamber penetrating the first chamber; an elastic capsule disposed in the first chamber; a pressure-transmitting medium accommodated in the second chamber; pressing covers, which are respectively disposed on the first side and the second side of the pedestal body; a first pipeline disposed on the first side of the pedestal body; and a second pipeline disposed on the second side of the pedestal body. The slip casting pressure gauge pedestal device is advantageous in that the pressure transmission data is accurate, the pressure-bearing capability is strong, and the service lifetime is long.
