Abstract
The invention discloses a method for automatically judging a water-to-binder ratio of mudjacking slurry. The method comprises the steps that a detection vessel provided with a slurry inlet and a slurry outlet is supported on a weighing sensor; the weight of the detection vessel is detected via the weighing sensor in real time; an appropriate amount of slurry is manually prepared according to a standard allowable maximum water-to-binder ratio and a standard allowable minimum water-to-binder ratio; the detection vessel is filled up for several times; when the detected real-time weight W is qualified, a control center transmits a qualified signal to control a relevant executive component to be communicated with the slurry outlet of the detection vessel and deliver the qualified slurry to a slurry storage barrel for standby; and when the detected real-time weight W is unqualified, the control center transmits an unqualified signal to control a relevant executive component to deliver the slurry delivered by the slurry outlet of the detection vessel to a waste slurry barrel. The method has the advantages that whether the water-to-binder ratio of the slurry is qualified can be dynamically judged in real time, the unqualified slurry is automatically removed, and the qualified slurry is reserved, so that the mudjacking quality is ensured.

Technical field
Content of the present invention belongs to prestress hole path pressure grouting concrete slurry water-cement ratio detection technique field, and particularly a kind of By Measuring The Volume Density judges the automatic judgement mud jacking slurries glue ratio method of water-binder ratio.
Background technology
Prestress hole path pressure grouting is that prestress engineering is constructed one of most important operation, and whether mud jacking is closely knit, and direct relation security and the permanance of structure.And the factor affecting squeezing quality is except the factors such as press mortar, construction technology, mud jacking equipment, construction management, also directly related with the ratio of water and grouting material consumption and water-cement ratio.Water-cement ratio is crossed conference and is caused anti-pressure ability to reduce to works and carbonation rate is fast, carbonation depth is large, the problems such as perviousness increase, impermeability and frost resistance reduction; Unit consumption of water controls bad meeting and causes mix to block up the phenomenons such as pump, bleeding, segregation, and the defect such as honeycomb, pitted skin, sand line that structural member surface is formed.Therefore " highway bridge construction technical manual " (JTG/T F50-2011) clear stipulaties, the water-cement ratio of prestress hole path pressure grouting liquid will control between 0.26 ~ 0.28, to guarantee squeezing quality.
Summary of the invention
Object of the present invention is just to provide a kind of dynamic, automatically judges that whether water-cement ratio is qualified, and is automatically got rid of by underproof slurries, retains qualified slurries, thus ensures the method for the automatic judgement mud jacking slurries water-cement ratio of squeezing quality.
Solution of the present invention is such:
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 by having into and out of the inspection instrument of slurries mouth, being detected the weight of inspection instrument by LOAD CELLS 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 is filled in gradation, utilizes LOAD CELLS to measure the weight W of slurries when maximum water-cement ratio respectively

2compare, work as W
1≤ W≤W
2time, judge that slurries water-cement ratio is qualified, otherwise be defective;
(4), qualified slurries supplying step: when the real-time weight W measured is qualified, control center sends qualifying signal, controls the grout outlet that relevant execution unit connects inspection instrument, qualified slurries is transported to slurry storing tube for subsequent use;
(5), defective slurries treatment step: when the real-time weight W measured is defective, control center sends defective signal, controls relevant execution unit and the slurries that the grout outlet of inspection instrument transfers out is transported to useless slurry cylinder.
Advantage of the present invention can in real time, dynamically judge that whether slurries water-cement ratio is qualified, and automatically got rid of by underproof slurries, retains qualified slurries, thus ensure squeezing quality.
