An automatic grout fluidity tester and its application method

Abstract

The invention discloses an automatic slurry fluidity tester and its use method, comprising an automatic stirring system, an automatic timing system, a position measuring system and an automatic valve control system; the automatic stirring system, the position measuring system and the automatic timing system are respectively connected with the The automatic valve control system is electrically connected, the automatic timing system is electrically connected to the position measurement system; the automatic stirring system: controls the stirring pot to automatically complete the automatic mixing of the press slurry and water; Descending distance; automatic valve control system: control the opening and closing of the first valve installed at the lower end of the stirring pot and the second valve installed at the lower end of the fluidity measuring cylinder; automatic timing system: start timing from the second valve opening until the second valve Stop timing when the second valve is closed. The invention realizes the automatic judgment and automatic timing of the flow end point of the grout material, so that the fluidity test process of the grout material is automated.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to an automatic grout fluidity tester and a method for using the same. Background technique [0002] Pressing grout is a product specially used for post-tensioned prestressed pipe (hole) grouting construction. It is optimized from a variety of high-quality cement-based materials and high-performance admixtures. It has excellent fluidity, stable slurry, and filling degree. Good, adjustable setting time, no shrinkage, micro-expansion, high strength, no harmful substances to steel bars, etc., are widely used in various railways and highways Post-tensioned prestressed bridge channel grouting, various concrete structure joints Leak stop grouting, curtain grouting, anchor grouting, gap filling or repairing, etc. [0003] The fluidity measurement of the grout affects the application effect of the grout. In the post-tensioned prestressed structure, the filling and protection of t...

Problems solved by technology

According to the "Technical Specifications for Highway and Bridge Construction" (JTG / TF50-2011), the existing test equipment is mainly manual operation, the stirring process of the grout is separated from the fluidity test, and the test fluidity of the grout is manually measured, including manual Judging the end of the experiment and manual timing, due to the large error of manual operation, it is easy to cause disputes in the application process
