Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a pressure-conducting and diverting device suitable for vacuum preloading foundation reinforcement. Background Art

[0002] Vacuum preloading is a soft soil foundation reinforcement process. This process covers a plastic film on the foundation to seal the foundation, and then installs a jet pump to create a vacuum. The jet pump is connected to the horizontal drainage channel through a film outlet device. The vacuum pressure is transmitted to the vertical drainage channel through the horizontal drainage channel, and finally transmitted to the foundation. The water and air in the foundation are discharged to the outside of the membrane through the drainage channel and the jet pump.

[0003] However, the pressure-conducting and diverting device for vacuum preloading foundation reinforcement in the prior art separates the water-gas mixture through the pressure-conducting and diverting device composed of a water ring vacuum pump and a submersible pump, and transports the accumulated water and the gas respectively, to achieve vacuum preloading foundation reinforcement, which can improve efficiency, save electricity and a large amount of manpower. However, the existing pressure-conducting and diverting device has no self-cleaning function, and the small particles of impurities in the accumulated water will gradually clog the surface of the filter, resulting in the inability of the filter to filter the accumulated water normally, so that the accumulated water in the foundation cannot be discharged normally, affecting the normal progress of the vacuum preloading foundation reinforcement, and is not conducive to people's use.
