Abstract

The invention provides a precise slurry-isolating pressure gauge for eliminating an underground building curtain defect dangerous case based on a grouting method, which comprises a shell, wherein the bottom end of the shell is fixedly connected with a pipeline pressure mechanism, the top of the pipeline pressure mechanism is fixedly connected with a pressure gauge module, the two sides of the upper part of the shell are provided with protective cover mechanisms, and the lower part of the pipeline pressure mechanism is fixedly connected with a sealing cover mechanism. The pressure gauge module is protected against vibration and freezing, and is connected with other pipelines in a flange connection mode, so that the sealing performance is higher, the pressure test is more accurate, the piston type pressure output mechanism ensures that the pressure sensing mechanism can better measure pressure in a state of not contacting slurry, and when the instrument is not used, the protective cover is closed and the sealing cover is closed, so that the stability of the instrument can be protected, and the service life of the instrument is prolonged.

Description

technical field [0001] The invention relates to equipment for civil construction, in particular to a grout-separated precision pressure gauge for eliminating dangerous situations of curtain defects in underground buildings based on the grouting method. Background technique [0002] With the deepening transformation of our country's construction field, more and more people are developing and utilizing underground space. In order to meet the needs of construction, we must first make underground building curtains around the foundation pits that will be excavated. Because these underground building curtains are It is completed underground through relevant mechanical equipment, so it is relatively easy to cause engineering defects. These defects are not easy to find and will only be revealed during the construction and excavation process. After the defects are revealed, they often cause dangerous situations such as water gushing and quicksand. If it cannot be blocked in time, it ...
