Chemical grouting flowmeter, measuring method and pneumatic single cylinder double-liquid type chemical grouting pump

Abstract

The invention relates to a chemical grouting flowmeter for measuring high-viscosity solution, a method for measuring flow by using the flowmeter and a pneumatic single cylinder double-liquid type chemical grouting pump applying the chemical grouting flowmeter. The pneumatic single cylinder double-liquid type chemical grouting pump comprises an adjustable air valve, the chemical grouting flowmeterand a control circuit; an air cylinder is provided with a main electromagnetic air valve and a sub-electromagnetic air valve; a displacement sensor is provided with a left approach switch and a rightapproach switch; the tip of a hydraulic cylinder is provided with an A component grout-feeding electromagnetic liquid valve, a B component grout-feeding electromagnetic liquid valve and a grouting electromagnetic liquid valve; and the hydraulic cylinder is provided with a mixer for mixing grouting liquid. With the adoption of the chemical grouting flowmeter, the method and the pneumatic single cylinder double-liquid type chemical grouting pump, the flow of chemical grouting can be accurately measured, so that the proportion of chemical grouting components can be continuously adjusted, and theuse is convenient.

Description

technical field [0001] The invention relates to a flowmeter for measuring high-viscosity solution for chemical grouting, a method for measuring flow by using the flowmeter and a pneumatic single-cylinder double-liquid chemical grouting pump using the chemical grouting flowmeter. Background technique [0002] Chemical Grouting is to prepare a certain chemical material (inorganic or organic material) into a real solution, and use a chemical grouting pump and other pressure-feeding equipment to pour it into the formation or gap to make it diffuse, gel or solidify, so as to It is a ground treatment and concrete repair technology to increase the strength of the ground, reduce the permeability of the ground, prevent the deformation of the ground, and repair the cracks of concrete buildings. That is to say, chemical grouting is an engineering technology that combines chemistry and engineering, applies chemical science and chemical slurry materials to solve foundation and concrete d...

Problems solved by technology

[0014] The technical problem to be solved by the present invention is that it is inconvenient to measure the flow rate of chemical grouting, and a flow meter for measuring the flow rate of chemical grouting is provided. The flow meter can measure the flow rate of non-conductive liquid, and the measurement accuracy is high; The flow measurement method using the above-mentioned flowmeter; the technical problem that the present invention also solves is that the chemical grouting components cannot be continuously adjusted, the adjustment is inconvenient, the use cost is high, and the data cannot be recorded in real time.
