Description

Technical Field

[0001] The present invention relates to the technical field of monitoring of fluid-solidified soil, and particularly to a real-time flow performance monitoring system and adjustment method for a fluid-solidified soil mixing equipment. Background Art

[0002] Due to its advantages of convenient construction, excellent filling effect, controllable strength development, stable solidification effect, and remarkable ability to consume solid waste, fluid-solidified soil has been widely used to replace lime soil and plain soil for foundation reinforcement, foundation pit backfilling, backfilling of fat grooves, backfilling of pipe galleries, backfilling of bridge backs, etc. However, it is difficult to control the performance of fluid-solidified soil, especially the flow performance related to the forming quality. This is because the main component material of fluid-solidified soil, soil, has a very wide variety and source. The soil used to prepare fluid-solidified soil can be selected from construction waste soil, sludge, shield mud, natural soil, industrial solid waste, etc. These materials vary in physical and chemical properties such as composition, particle size distribution, and moisture content. Even for the same material, due to factors such as production time and formation depth, there are differences in particle size distribution, moisture content, and organic matter composition. This results in unstable performance of fluid-solidified soil, especially during on-site pouring, and the fluctuation of the flow performance closely related to the forming quality is more significant.

[0003] How to solve the above technical problems is the subject faced by the present invention. Summary of the Invention

[0004] In order to solve the deficiencies of the prior art, the present invention provides a real-time flow performance monitoring system and adjustment method for a fluid-solidified soil mixing equipment, which can effectively monitor the flow performance of fluid-solidified soil during pouring, provide reference parameters for performance adjustment, and ensure the construction forming quality of fluid-solidified soil.

The measuring bin is connected to the mixing bin, and the connection channel and the falling channel are controlled by the bin door. The liquid level gauge is located above the measuring bin and is connected to the data acquisition instrument. The collection bin is below the measuring bin, and the downward flow channel is controlled by the bin door. By obtaining the inflow volume of the fluid-solidified soil slurry in the measuring bin within a set time and comparing it with the data in the system database, the flow performance of the fluid-solidified soil is evaluated in real time, so as to realize the construction forming quality control of the fluid-solidified soil affected by factors such as soil type, particle size distribution, and moisture content during the continuous construction process.

[0007] The mixing bin is a mixing bin for fluid-solidified soil; the mixing bin doors are respectively located at the bottom and the side bottom of the mixing bin, namely the side bottom bin door and the bottom bin door of the mixing bin.

The data processing and control system internally stores a comparison database of the flow performance of fluid-solidified soil, and processes and analyzes the data collected by the data collector.

[0015] The electrically controlled bin door is controlled by the data processing and control system, and its control program: when starting the fluid-solidified soil flow performance test program, the side bottom bin door of the mixing bin opens, and the fluid-solidified soil in the mixing bin flows into the measuring bin. At this time, the test bin door is in a closed state. When the outflow time of the fluid-solidified soil reaches the set time, the side bottom bin door of the mixing bin closes. When the flow performance of the fluid-solidified soil is determined to be qualified, the bottom bin door of the measuring bin opens. When the flow performance of the fluid-solidified soil is determined to be unqualified, the side bottom bin door of the measuring bin opens.

[0023] A method for real-time flowability detection and adjustment of fluid-solidified soil production equipment includes the following steps:

[0024] S11: When the fluid-solidified soil in the mixing chamber is stirred and completed, start the fluidity test of the fluid-solidified soil; first, open the bottom side door of the mixing chamber, and the fluid-solidified soil in the mixing chamber flows into the measuring chamber; after a set time, close the bottom side door of the mixing chamber, and the liquid level gauge will measure the data of the position of the fluid-solidified soil slurry surface in the measuring chamber and transmit the obtained data to the data processor. After the data processor processes the slurry surface position information into volume data, it is transmitted to the data processing and control system through the data transmission line;

[0025] S12: After the data processing and control system receives the volume data of the flowing and solidified soil in the measurement bin, it evaluates the flowing performance of the flowing and solidified soil in the mixing bin through the established comparison database of the flowing performance of the flowing and solidified soil. When the volume of the measurement bin is within the normal range of the fluidity of the flowing and solidified soil, and when the flowing performance of the flowing and solidified soil in the mixing bin is determined to be qualified, the bottom bin door of the measurement bin is opened. When the volume of the measurement bin is within the range of too low or too high fluidity of the flowing and solidified soil and the flowing performance of the flowing and solidified soil in the mixing bin is determined to be unqualified, the side bottom bin door of the measurement bin is opened.

[0026] S13: When the flowing performance of the flowing and solidified soil in the mixing bin is determined to be unqualified, the result can be given according to the comparison database of the flowing performance of the flowing and solidified soil built in the industrial computer, and the flowing performance can be adjusted.
