Geotechnical engineering original position rotation contact-surveying vehicle

Abstract

The utility model relates to an in-situ rotating sounding vehicle for geotechnical engineering, which comprises a car body, a ground anchor, a hydraulic outrigger, a bearing base plate, an oil pump, a hydraulic device, a probing-rod dismounting ferrule, a probing-rod locating ring and a console with various control valves. The utility model is characterized in that the hydraulic device comprises two parallel hydraulic oil cylinders and piston rods; a shaft box and a main shaft are arranged between the two parallel hydraulic oil cylinders; the shaft box and the main shaft rise and fall synchronously with the two hydraulic oil cylinders and transfer penetrating pressure; an axis water channel and a rotating water faucet connected with a vehicle-mounted slurry pump are arranged on the main shaft; the probing-rod dismounting ferrule, a probing-rod close nipple with a joint water channel, the probing-rod hydraulic and pneumatic jigs are arranged on the lower end of the main shaft; the console comprises a control valve for the main shaft and the vehicle-mounted slurry pump motor, a control valve for fast rising, fast falling and floating falling of the two parallel hydraulic oil cylinders and a control valve for various jigs. The utility model has the advantages of reasonable structure, convenient operation, reliable movement and enabling the rotating penetration probe to penetrate up to eighty meters into hard stratum.

Description

technical field [0001] The invention belongs to penetrating equipment, in particular to an in-situ rotary penetrating vehicle for geotechnical engineering. Background technique [0002] The existing static penetration vehicle is an operation platform that provides penetration pressure and control for the static penetration test device according to the static penetration test method. Its basic components include the automobile engine, the oil pump driven by the automobile engine, the automobile chassis and its fixed The load-bearing bottom plate of the chassis, the hydraulic device installed on the load-bearing bottom plate, the probe rod dismounting ferrule connected to the hydraulic device for lifting the probe rod, the hydraulic device console equipped with multiple control valves, corresponding to the probe rod removal The guide and positioning ring of the probe rod supported on the load-bearing floor with the ferrule installed, the ground anchor and its oil motor, and fo...

AI Technical Summary

Problems solved by technology

[0003] Although the existing static penetrating vehicle can provide sufficient penetration pressure for the penetrating probe rod, it is difficult for the probe to penetrate into harder formations such as dense sandy soil layers. The main reason is that the strength of the probe rod is not enough In the case of hard formations, the penetration pressure can be reliably transmitted, causing the probe rod to bend or even break, and the ground anchor may also fail at the same time, causing the penetrating vehicle to lose its horizontal state, resulting in serious consequences of test failure
