Abstract
The utility model provides a measuring system for a grouting reinforcement process. The system comprises a grouting pump, an anti-knock pressure gage and an electromagnetic flowmeter. According to the grouting pump, an air compressor is adopted to serve as a grouting power source. A grouting pipe of the grouting pump is connected with the anti-knock pressure gage and the electromagnetic flowmeter through tee joints. The anti-knock pressure gage, the electromagnetic flowmeter and an inlet valve of the air compressor form a detection control loop. Therefore, a grouting process is monitored in real time, grouting efficiency and stability are improved, and grouting reinforcement quality is guaranteed.
Description
Technical field
The utility model relates to a kind of measurement system that disposes in grouting and reinforcing technology.
Background technology
In recent years, ground body slurry injection technique has obtained using widely.Carry out the grouting and reinforcing engineering at different geological conditionss, place, design scheme should satisfy the slip casting situation under the different grouting process, grouting parameter, slurries parameter condition of the sand body of on-the-spot geological conditions.
In the engineering, generally be to adopt large-scale air compressor machine as the slip casting power source, pressure is more stable, and pressure at expulsion is general constant in 0.8MPa.The hydraulic coupling that goes out of grouting pump generally big luffing occurs with the variation on stratum; Indoor grouting simulation test often adopts Manual pressure test pump as the slip casting power source, and grouting pipeline adopts withstand voltage rubber hose, and its rear end is connected with the hydraulic test pump Grouting Pipe.
The utility model content
The utility model provides a kind of measurement system for grouting and reinforcing technology, with real-time monitoring slip casting process, improves slip casting efficient and stability.
Scheme of the present utility model is as follows:
A kind of measurement system for grouting and reinforcing technology comprises grouting pump, anti-shock pressure meter and electromagnetic flowmeter; Grouting pump adopts air compressor machine as the slip casting power source, connects described anti-shock pressure meter and electromagnetic flowmeter by threeway on the Grouting Pipe of grouting pump, and the air intake valve of anti-shock pressure meter and electromagnetic flowmeter and air compressor machine constitutes the detection control loop.
The preferred HT-LDE type of above-mentioned electromagnetic flowmeter electromagnetic flowmeter.
The utlity model has following advantage:
The process of monitoring slip casting in real time improves slip casting efficient and stability, guarantees the grouting and reinforcing quality.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1: measurement system of the present utility model comprises anti-shock pressure meter, range 2.5MPa; HT-LDE type electromagnetic flowmeter, latus rectum 25mm.
Under grouting amount and the changeless situation of grouting pressure, the layer of sand crack is the principal element that influences slip casting effect, and slurries easily extend along the crack trend, cause adding solid and irregular structure bodies such as sheet, bulk occur.Because the uncertainty on stratum, and too much fissure-plane exists, and can cause adverse effect to underground surrounding rock of chamber stability, therefore, under the monitoring of measurement system, should be noted that following some:
(1) stablizes grouting pressure.In the engineering, generally be to adopt large-scale air compressor machine as the slip casting power source, pressure is more stable, and pressure at expulsion is general constant in 0.8MPa.The hydraulic coupling that goes out of grouting pump generally big luffing occurs with the variation on stratum.Highly pressurised liquid acts on the pressure meter can real-time monitored grouting serous fluid pressure size, according to manometric variation and slip casting face condition, at any time regulate the grouting pump air intake valve, regulate to give and press size, guarantee that antidetonation meter pressure table is stabilized between the 0.2-0.6MPa, guarantees the penetrating power of slurries in layer of sand.
(2) suitably adjust grouting amount.The HT-LDE electromagnetic flowmeter detects the injection rate of slurries in the slip casting process in real time, can measure the slurries amount of injecting layer of sand very accurately, thereby regulate the grouting pump air intake valve and give the pressure size, flow rate of grouting is generally controlled at 5～15L/min in the slip casting process, and maximum should not surpass 20L/min.Got through or stratum itself just exists under the situation in crack when the crack, suitably increase grouting amount filling crack, the existence that can alleviate because of fissure-plane causes the not good phenomenon of grouting consolidation effect.
(3) suitably increase slip casting hole count, minimizing injected hole distance.Increase the overlapping scope that adjacent hole adds solid, guarantee to add the whole slip casting effect of solid.
Claims (2)
1. a measurement system that is used for grouting and reinforcing technology is characterized in that: comprise grouting pump, anti-shock pressure meter and electromagnetic flowmeter; Grouting pump adopts air compressor machine as the slip casting power source, connects described anti-shock pressure meter and electromagnetic flowmeter by threeway on the Grouting Pipe of grouting pump, and the air intake valve of anti-shock pressure meter and electromagnetic flowmeter and air compressor machine constitutes the detection control loop.
2. the measurement system for grouting and reinforcing technology according to claim 1 is characterized in that: described electromagnetic flowmeter employing HT-LDE type electromagnetic flowmeter.
