Ultrahigh-pressure water jet device for cutting reinforced concrete slab and using method thereof

Abstract

The invention discloses an ultrahigh-pressure water jet device for cutting a reinforced concrete slab. The ultrahigh-pressure water jet device is characterized in that the device comprises a numericalcontrol system, an automatic sand supply system, an ultrahigh-pressure generator and a water cutting main machine; the numerical control system comprises a control computer, a keyboard, an operationplatform and rollers; the automatic sand supply system comprises a cover, a handle, a sand supply controller, a sand cylinder, a sand discharge hole and a roller foot stool; the ultrahigh-pressure generator comprises a monitoring hole, a pressurizing main machine and a foot support, the monitoring hole is located in the side face of the pressurizing main machine, and the foot support is located atthe bottom of the pressurizing main machine; and the water cutting main machine comprises a stable base, an X-direction workbench, an X-direction rail, an X-direction crawler belt disc, an X-direction crawler belt, an emergency brake, an X-direction pedestal, a Y-direction working bridge frame, a Y-direction crawler belt, a Y-direction rail, a water jet cutter arm, a sand tank and a water jet cutter spray head. By means of the ultrahigh-pressure water jet device, the problems of large current concrete cutting raised dust and noise, irregular cutting and the like can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of concrete slab cutting in civil construction, in particular to an ultrahigh-pressure water jet device for cutting reinforced concrete slabs. Background technique [0002] Water cutting technology, also known as water jet, water jet cutting technology. As the name implies, it uses water as a knife to pressurize the water to an ultra-high pressure level. Generally, the high pressure ranges from 200MPA to 400MPA. After passing through the small holes of the nozzle, the kinetic energy of the water is increased to a certain extent, acting on the material, and the water can be used. Energy for material cleaning, delamination, cutting. The water jet is a high-speed water stream of different shapes formed by the nozzle, and the flow rate of the jet depends on the pressure difference before and after the nozzle outlet section. [0003] Contemporary waterjet technology continues to improve, and mixing other substa...
