The beneficial effect lies in: realizing the automatic monitoring of the deep hole grouting waterstop construction process, surface deformation, grout mix ratio, and grouting process parameters, completing real-time data processing and analysis through the information monitoring platform, and guiding the grouting construction operation and process parameters. Adjust in time to realize the effective control of the construction process of deep hole grouting and water stop, strengthen the management of the construction process, and ensure the effect of grouting and water stop.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a real-time monitoring system and method for deep-hole grouting and water-stop construction. Background technique [0002] With the rapid development of urban underground space development and utilization, the buried depth of subway projects is getting larger and larger, and the influence of groundwater is becoming more and more serious. In order to ensure construction safety, effective water-stop measures must be taken for the variable-section sections, communication passages, shafts or cross passages that are constructed using the mining method. Deep hole grouting waterstop has been widely used in mining tunnel construction because of its advantages and characteristics such as simple construction technology, less project investment, short construction period, and less site occupation. [0003] The monitoring and process control of parameters such as grout gel time, groutin...

AI Technical Summary

Problems solved by technology

[0004] 1) The measurement accuracy of raw materials and slurry in the background of mixing is poor

[0005] Existing problems: (1) The amount of cement is measured by 50kg / bag. After bagged cement is changed to filled cement, there are problems in weighing, conveying and feeding

(2) The amount of water is roughly measured by marking on the side of the bucket, and the slurry mix ratio cannot be effectively controlled

(3) The amount of grout is counted in the unit of "tank", and the total grouting amount is not accurately grasped

[0006] 2) The grouting pump cannot read key process parameters such as grouting pressure and slurry flow rate

[0007] Existing problems: (1) The grouting pressure gauge has a large range (to prevent the pressure gauge from being damaged due to sudden pressure changes), and the grouting pressure is not easy to read on site

(2) The grouting speed is only adjusted by the gear lever, and the actual flow rate of the grout cannot be monitored

(3) There is no measuring device for the amount of grouting, which is estimated by the on-site workers

When the grouting pressure is too high, the grouting body will have a large deformation, which will bring great safety hazards to the project itself and the surrounding environment.

[0009] To sum up, the construction process of deep hole grouting and waterproofing is basically out of control, and key technical parameters such as grouting ratio, grouting pressure, grouting volume, grouting speed, and grouting time cannot be effectively monitored and controlled. , not only the quality of grouting and water-stop construction cannot be guaranteed, but also greatly limits the development of grouting technology
