Fig. 1 is structural representation of the present utility model.
In accompanying drawing: 1, stock inlet 2, support 3, LOAD CELLS 4, inspection instrument back up pad 5, inspection instrument 6, grout outlet 7, electric three-way valve 8, useless slurry bucket 9, slurry storing tank.
Embodiment
As shown in Figure 1, the present invention includes inspection instrument 5, inspection instrument support 2, the LOAD CELLS 3 be arranged on inspection instrument support, electric three-way valve 7 and control center.
Described inspection instrument 5 is for measuring the volume of slurries, and its stock inlet 1 is arranged on inspection instrument bottom, and grout outlet 6 is arranged on inspection instrument top;
Described LOAD CELLS 3 is arranged between inspection instrument back up pad 4 and support 2, and is connected with control center by data line, for carrying out Real-Time Monitoring to the weight of inspection instrument 5, and Monitoring Data is delivered to control center;
Described useless slurry feed pipe for mortar stop valve and storage slurry feed pipe for mortar stop valve adopt electric three-way valve 7, be arranged on the pipeline that is connected with grout outlet 6, and be connected with control center by control line, controlled center controls, for defective slurries being discharged to useless slurry bucket 8, qualified slurries are discharged to slurry storing tank 9.
Described control center is used for the weight of Real-Time Monitoring inspection instrument 5, and compares with the weight standard value of setting, judges that whether slurries water-cement ratio is qualified, controls the action of electric three-way valve 7.
A method for automatic judgement mud jacking slurries water-cement ratio, comprises step:
(1), the real time measure inspection instrument weight step: being supported in LOAD CELLS 3 by having into and out of the inspection instrument 5 of slurries mouth, being detected the weight of inspection instrument 5 by LOAD CELLS 3 in real time;
(2), mud jacking slurries water-cement ratio setting procedure: the maximum water-cement ratio allowed according to standard and minimum water-cement ratio, human configuration slurries are appropriate respectively, and inspection instrument 5 is filled in gradation, LOAD CELLS 3 is utilized to measure the weight W of slurries when maximum water-cement ratio respectively
1with weight W during minimum water-cement ratio
2, by W
