Technical field
The utility model relates to a kind of laser image data technology, specifically a kind of device of drill bit pressurized parameter when obtaining rig and advancing.
Background technology
A large amount of construction of tunnel are arranged in China's water conservancy and hydropower, the field of traffic, the construction of tunnel geological disaster is the key factor of restriction constructing tunnel, because the tunnel front geological condition is not clear, unforeseen geological disaster often appears often, as gushing water, prominent mud, cave in, rock burst and pernicious gas etc.In a single day disaster takes place, and the facility that gently then destroy by rush of water flood the tunnel, and normal construction is forced to interrupt; Heavy then cause great casualties, produce enormous economic loss, even therefore some underground construction can be forced to suspend or relocate.
As everyone knows, the spatial distribution model and the numeral expression of ground geologic body (mechanics) set up in a most important job of any engineering relevant with ground or problem in science exactly.The formation of geology geotechnical body and evolution history are general very long and changeable, and this has just caused geotechnical body spatial distribution complexity and the diversity with various different physics and mechanical property.An engineering duty the most common, most important when therefore, using auger or rig in the earth, to hole in the construction works such as engineering investigation, Foundation Design, slope reinforcing.The borehole log of engineering investigation probing generally is to be edited and recorded according to core that collects and soil sample by geology and geotechnical engineering teacher.Firsthand information according to these acquisitions, people can rationally extrapolate in the basic unit that experience and understanding are arranged, thereby set up field dynamics space, ground peace section model, and model is applied to design, produces and construction with numeral, yet, the record of construction drill is is generally edited and recorded by the drilling operation personnel, about adopting the live data of probing of digital monitoring instrument record and monitoring boring actually rare.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, detection accuracy is high, anti-interference, the device of measuring drill bit pressurized parameter when obtaining rig easily and advancing.
For achieving the above object, the utility model adopts following technical proposals:
A kind of device of drill bit pressurized parameter when obtaining rig and advancing, comprise drilling cramp, drilling cramp one end is provided with the center with frame, the other end is provided with drilling cramp top forehead, drilling cramp is provided with unit head servicing unit and drill holder, the unit head servicing unit links to each other with unit head, and unit head is corresponding with drill holder; Unit head servicing unit afterbody is connected with hydraulic tube one end by the head that is tightly connected; The other end of hydraulic tube connects the hydraulic pump of rig; Be connected with hydrostatic sensor by joint on the hydraulic tube; Hydrostatic sensor links to each other with data processing equipment by data wire.
