Problems solved by technology
However, in actual working conditions, due to the long-term immersion and use of the drainage pump, failures or corrosion and burnouts often occur. Not only maintenance and replacement require shutdown operations, but also the cost of equipment for construction operations is high, and the drainage pump is used for a long time Drainage requires a certain amount of electric energy, which is not conducive to energy saving and emission reduction

Embodiment 3
[0031] as attached figure 1 As shown, the switch button 2 on the electrical control cabinet 1 is in the right position, the drainage device enters the liquid level control self-draining mode, the electrical control cabinet 1 instructs the electric valve 3 to open, the pressure relief valve 5 is normally closed, and the water in the soft foundation enters the main The liquid level controller b is triggered in the tank 7, and the liquid level controller b transmits the trigger signal to the electrical control cabinet 1. The electrical control cabinet 1 instructs the electric valve 3 to close, the pressure relief valve 5 is opened, and the water in the main tank 7 is self-draining. The valve 8 is discharged; when the water level in the main tank 7 drops, the liquid level controller c is triggered, and the liquid level controller c transmits the trigger signal to the electrical control cabinet 1. The electrical control cabinet 1 instructs the electric valve 3 to open, the pressure ...

The invention relates to a soft foundation water-gas separation vacuum pre-pressure drainage device and a control method thereof. The soft foundation water-gas separation vacuum pre-pressure drainagedevice comprises a water-gas separation tank, a vacuum pump set, a drainage plate water collection system, and an electric appliance control system. The water-gas separation tank comprises a main tankand a secondary tank, wherein the main tank and the secondary tank form a closed container; the vacuum pump set is communicated with the top of the main tank; the drainage plate water collection system is communicated with the main tank, a vent hole is formed at the top of the main tank, a pressure relief valve is arranged on the vent hole, a self-draining valve is arranged at the bottom of the vent hole, a liquid level controller is arranged in the main tank, and a water discharge pump is arranged in the secondary tank, so that three modes of the water-gas separation vacuum pre-pressure drainage device are formed, that is, the pump direct discharge mode, the liquid level control pump discharge mode, and the liquid level control self-draining mode. According to the invention, the three modes of timely conversion can be achieved by the electric appliance control system according to different drainage states for the purpose of safe drainage, continuous drainage, energy saving and high efficiency.
Description
technical field [0001] The invention relates to the technical field of soft ground treatment, in particular to a water-gas separation vacuum pre-pressing drainage device for soft ground and a control method thereof. Background technique [0002] The vacuum preloading method uses an airtight sealing membrane to isolate the reinforcement area from the outside atmosphere, uses the sand cushion of the horizontal drainage channel and the plastic drainage board of the vertical drainage channel, and uses the filter tube embedded in the sand cushion as the water absorption pipeline. The vacuuming device performs air extraction to form a vacuum and negative pressure under the membrane, so that an effective pressure difference is formed between the interior of the soil body and the drainage channel and the sand cushion, so that the pore water and the spaced air in the soil body are continuously removed from the vertical and horizontal channels. discharge, so as to achieve the effect o...
