Embodiment Construction

[0040] In the following, the present invention will be further described in conjunction with the drawings and specific embodiments.

[0041] like figure 1 As shown, an automatic grouting system includes: a cement tank, a funnel, a first electric control valve, a cement slurry mixing pool, a cement slurry storage pool, a second electric control valve, a mud pump, an automatic grouting recorder, a first A water injection pipeline, a first flowmeter, a controller, a water glass tank, a water glass stirring tank, a delivery pipeline, a second flowmeter, a water glass storage tank, a second water injection pipeline and a third flowmeter.

[0042] The cement tank communicates with the funnel through the screw machine, and the electronic scale for weighing the weight of cement is arranged in the said funnel. The first electronically controlled valve is installed at the outlet of the funnel. The outlet of the funnel communicates with the cement slurry mixing tank. The cement slurry...

Abstract

The invention relates to an automatic grouting system comprising a cement tank, a funnel, a first electric control valve, a cement slurry stirring pool, a cement slurry storing pool, a second electric control valve, a cement slurry pump, an automatic grouting recorder, a first water injection pipeline, a first flow meter, a controller, a sodium silicate tank, a sodium silicate tank stirring pool, a conveying pipeline, a second flow meter, a sodium silicate storing pool, a second water injection pipeline and a third flow meter. By the adoption of the automatic grouting system, the slurry manufacturing process is controlled and monitored through an electronic scale, the electronic control valve, the flow meter, the automatic grouting recorder and the controller, the requirements existing during manual slurry manufacturing and monitoring are reduced, the work efficiency is improved, and labor cost is reduced.

Description

technical field [0001] The invention relates to cave grouting technology. Background technique [0002] In the construction process of subway shield starting, receiving, excavation, tunnel and mine excavation, water gushing and sand gushing often occur due to complex geological conditions or insufficient construction experience. In order to ensure the stability of the ground, filling due to water gushing and sand gushing The resulting underground voids (such as karst caves) can avoid the risk of water gushing and sand gushing from happening again. Therefore, corresponding treatment measures need to be taken. In order to achieve the effect of rapid plugging and fill the formation voids, inject single and double grout ( Cement - water glass) alternate reinforcement method for sealing. [0003] At present, in the production of slurry, it is completely dependent on manual pulping. Firstly, the demand for personnel is large. Secondly, it is not easy to ensure accurate measuremen...
