Tunnel radio laser laying out apparatus
Technical field
The utility model relates to a kind of Underground Engineering Excavation laser laying out apparatus, more specifically relates to a kind of tunnel radio laser laying out apparatus, especially the laser laying out apparatus of excavated section outline line and big gun hole location setting-out in the drilling and blasting method constructing tunnel.
Background technology
At present in the drill bursting construction of underground cavern tunneled network, the location setting-out of excavated surface generally is in the state in artificial instrument center line survey, big gun hole, steel ruler location, waste time and energy, inefficiency, can not satisfy the urgent requirement in time of huge engineering duty, and location setting-out low precision, cause out break easily, influence construction quality, progress and cost.
Utilizing laser projection carrying out setting-out construction is a kind of good settling mode.In the present laser projection setting-out technique, laser orientation instrument is simple and practical a kind of, utilizes the laser instrument that is placed on tunnel top and the abutment wall, emission and coincidence of tunnel center line or parallel laser beam, thereby the midline position of localized tunnel.This technology has cheap, simple in structure, visible emitting, do not take characteristics such as tunnel traffic spacial influence construction, can indicate the direction of tunnel piercing and the gradient, demarcation tunnel midline position, but this instrument only can be indicated center line, can not locating wheel profile and big gun hole, be difficult to handle crooked tunnel, still need in the use and manually determine to measure each big gun hole, workload is very big, and accurate inadequately.
A kind of technology that can carry out the tunnel cross-section laser lofting has neatly appearred recently---and laser lens scanning projection setting-out technique, for example Chinese invention patent publication number CN1262378A is in disclosed laser lofting instrument for tunnel cross-section on August 9th, 2000.This technology is to drive the object lens translation by stepper motor, and the laser beam exit direction that changes fixed laser in the instrument scans, and realizes that the laser point projection indicates the function of locating wheel profile and a plurality of borehole points on profiled outline and the excavated section.This class technology and the corresponding instrument part that comes with some shortcomings in actual applications: self poisoning is difficulty comparatively, needs measuring apparatus to cooperate, and is difficult to freely establish the station, such as being placed on the king-pile point, has taken the tunnel traffic space, influences constructing tunnel; Processing curved tunnel inconvenience; Because the relative aperture of object lens is limited, sweep limits and distance are subject to certain restrictions, and the tunnel cross-section that for example needs setting-out is if bigger, and then lofting instrument must be away from excavated surface.
Summary of the invention
The purpose of this utility model is to be to provide a kind of tunnel radio tunnel laser laying out apparatus, and this instrument can be implemented in laser positioning setting-out apace in tunnel and other underground engineering construction; In use can allow instrument self locate easily, and laser scanning setting-out scope is not subjected to setting-out position and distance limit, do not influence the constructing tunnel traffic, location setting-out precision height can easyly automatically be handled curved tunnel, arbitrary cross-section form and drilling and blasting schema arbitrarily.
For achieving the above object, the utility model adopts following technical measures: this laying out apparatus is made up of computer, servo type electronic total station, semiconductor laser, serial ports wireless communicator.Control software is housed in the computer, and the serial port of the serial port of computer and servo type electronic total station is connected the serial ports wireless communicator respectively, carries out the transmission that is connected of data and control signal between two serial ports wireless communicators; Semiconductor laser installing is in the inside of total station survey rotatable parts, and laser beam perforate from the total station survey rotatable parts casts out.Under computer software control, laying out apparatus carries out self poisoning by the measurement of radio communication control total powerstation, rotates by the control total powerstation to make laser project on the tunnel excavation work plane, reaches the setting-out purpose.Computer software has carried out the software copyright registration, and dbase is " a tunnel piercing automatic station-keeping system ", software copyright registration number 2007SR01366.Its workflow is as follows:
(1) system initialization is promptly opened computer, wireless communicator, laser instrument and total powerstation, makes them in running order, and definite wireless communicator and total powerstation operate as normal;
(2) backsight point of observing oneself know with total powerstation, system calculates self-position (north, east and elevation) and orientation (north to) automatically;
(3) the axis geometric data in the whole tunnel of input under graphic interface, the morphological data of section and drilling and blasting schema (section big gun hole design scheme) comprise any multistage tunnel of straight line and circular curve type, the excavated section of arbitrary shape and big gun hole site;
(4) rotation of control total powerstation, the distance of measuring current excavation work section and the angle of survey mark, the tunnel axis three-dimensional data that contrast has been imported, calculate the characteristic point (springing, summit and abutment wall positive and negative zero point etc.) of excavated section profile and the three-dimensional coordinate in big gun hole;
(5), calculate the characteristic point of excavated section profile and the total powerstation of big gun hole correspondence and rotate horizontal H angle and vertical V angle according to the data of laying out apparatus self poisoning; The rotation of control total powerstation makes outline line point and big gun hole site that laser beam projects needs the location, guiding operation personnel's mark, boring.
(6) after setting-out is all finished, the figure as a result and the record of output setting-out.
The utlity model has following advantage and effect: 1. setting-out system self poisoning is easy; Owing to adopted computer software analysis, utilize total powerstation high-acruracy survey known point, can determine the three-dimensional coordinate of system itself apace, easy and simple to handle, very favourable to the tunnel setting-out of curve complexity; Therefore system can freely establish the station, the setting-out system can be installed in abutment wall eminence or top in construction, does not influence the Construction traffic traffic in the tunnel, saves the engineering time.2. the radio communication system of Cai Yonging makes the setting-out system can be installed in the optional position, has reduced the influence to traffic in the tunnel; Make the staff to operate simultaneously away from the deathtrap, safer.3. setting-out precision height because adopted the mechanical body of total powerstation as systematic survey and rotational positioning, angle measurement accuracy can reach 1 second and more than, calculate thus, at 400 meters transect layout precision Yue Keda 1mm.4. built-in laser instrument does not influence the function of electronic total station, makes the original equipment of this construction of total powerstation and surveying and mapping unit to use as usual, says that from this angle the cost of laser lofting system is very low; Can rotate on a large scale by 360 degree simultaneously, setting-out compliance is strong.5. system is adapted to complicated drilling and blasting schema, and setting-out speed is fast.On indoor computer software, handle in advance, the drilling and blasting schema of storage tunneling section, operate with graphical interfaces during site operation, simple and clear, quick, saved the engineering time.
