Abstract
The invention discloses a kind of intelligent rapid setting-out methods suitable for drillhole blasting.For the feature that Practical Project setting-out efficiency is slow, precision is low, extend line coordinates according to the blasthole at blasthole inclination angle, blasthole aperture coordinate and any elevation and there is fixed mathematical relationship, it is compiled into customized coordinate transformation program, and be embedded in high precision total station, it realizes in irregular contoured surface Automatic-searching, the actual aperture coordinate of locking.The present invention can be used in the excavation project of the industries such as water conservancy and hydropower, traffic, mine, to improve blast working setting-out quality.
Description
Technical field
The invention belongs to construction technology in geotechnical engineering field, in particular to a kind of intelligent setting-out side suitable for drillhole blasting
Method.
Background technique
Construction lofting is the necessary links in Current Engineering Construction.Work not only can be improved in the efficient, accurate of construction lofting
Cheng Zhiliang, while can accelerate construction progress, bring huge economic benefit.Compared to Other Engineering, drillhole blasting is to construction lofting
Required precision it is stringenter, if deviation occurs in setting-out, undesirable demolition effect will be directly contributed, may be deposited under serious conditions
In security risk, therefore lifting construction setting-out technique is significant.Traditional construction lofting technology is first to carry out initial designs, root
It looks for a setting-out at the scene according to design point, but due to live out break, tends not to smoothly look for a little, can only re-measure
Afterwards, Secondary Design and setting-out are carried out.Whole process elapsed time, and program is tediously long.If a kind of setting-out technique can be invented,
Can be by the situation at perception scene when first time setting-out, and can be handled rapidly, it will be blasting engineering that setting-out is completed at scene
Construction provides huge convenience, and brings apparent economic benefit.
Summary of the invention
The object of the invention is to the situations according to the above-mentioned prior art to propose one for existing construction lofting technology
Kind is suitable for the simple process, strong operability, the intelligent setting-out technique for enhancing construction efficiency of drillhole blasting.
Technical solution of the present invention is successively made of following step:
1, initial aperture coordinate is transmitted and is stored into high precision total station.
2, the exchange program of initial coordinate and actual openings coordinate is embedded in high precision total station.
3, one group of contoured surface is formed by explosion, the smooth no requirement (NR) to contoured surface.
4, contoured surface is formed to explosion using high precision total station to measure, and pass through the initial coordinate and conversion of insertion
Program determines practical setting-out coordinate.
5, setting-out is completed.
In order to further enhance the efficiency of the practice and precision of setting-out:
1, the total station that the present invention uses is high precision total station, embeddable self defining programm.
2, initial coordinate of the invention can be by working out corresponding data format, and transmission storage is into total station.
3, initial coordinate of the invention and the mathematical procedure of the exchange program of actual openings coordinate are as follows:
Exchange program determines corresponding in the drilling of any elevation according to the initial aperture coordinate of design and blasthole inclination angle
Actual coordinate.If initial aperture coordinate is (x1,y1,h1), blasthole inclination angle is set as α, and target elevation is h2, it is thus necessary to determine that it is practical to sit
Mark (x2,y2,h2)。
x2=x1+(h2-h1)cotα
y2=y1+(h2-h1)tanα
When total station positions earth's surface any point, its elevation coordinate is perceived immediately, and by this exchange program, exports this
Blasthole actual coordinate (the x of elevation1+(h2-h1)cotα,y1+(h2-h1)tanα,h2)。
4, pass through the design level coordinate of upload, vertical coordinate (x1, y1) and rock mass exposure at present actual height h3Really
Determine the setting-out transition point A point in attached drawing 1.
5, according to current displaing coordinate, the plug-in for comparing insertion calculates A point height h in real time3Corresponding level
With vertical coordinate, and to the point move.
6, observation elevation variation in movement, and the meter that displaing coordinate and plug-in are determined based on actual height is compared rapidly
Coordinate is calculated, the error of the two meets precision when within 5%, that is, determines that it is practical layout point, completes setting-out.
Setting-out process in present invention combination drillhole blasting work progress passes through insertion initial coordinate and actual openings coordinate
Conversion journey, complete construction lofting when contoured surface has out break.Existing high precision total station insertion can be used in the present invention
The function of self defining programm, method is simple and easy, setting-out process automation and intelligence, and setting-out is reliable with positioning result.

Specific embodiment
The invention will be described further With reference to embodiment, in embodiment by taking contoured surface is owed to dig as an example.If
Implement explosion, slope excavating height 10m in a certain side slope, blasthole tilt angle is 60 °, array pitch 3*3m between blasthole.Certain bench
The working face of out-of-flatness is formed after explosion, current bench excavation design altitude is EL.1000m.
1, by the coordinate of initial designs layout point B (6 in attached drawing 1 are signified) by working out corresponding data format, transmission
Storage is into total station.
2, the mathematical routine to convert automatically is embedded in total station.
According to the coordinate of initial designs layout point B and blasthole inclination angle, practical seat corresponding in the drilling of any elevation is determined
Mark.If the coordinate of layout point B is (x1,y1, 1000), 60 ° of blasthole inclination angle, target elevation is h2, it is thus necessary to determine that actual coordinate (x2,
y2,h2)。
x2=x1+(h2-1000)cot600
y2=y1+(h2-1000)tan600
When total station positions earth's surface any point, immediately by its elevation coordinate, and by this exchange program, this is exported
Blasthole actual coordinate (the x of elevation1+(h2-1000)cot600,y1+(h2-1000)tan600,h2)。
3, according to the horizontal coordinate of B point, vertical coordinate (x1, y1), the determining identical horizontal vertical coordinate in earth's surface exposure
Setting-out transition point A point (5 in attached drawing 1 are signified), and determine its elevation coordinate.
4, A point height h is calculated by the exchange program program of insertion according to the elevation of setting-out transition point A in real time3It is right
Level and vertical coordinate on the blasthole extended line answered.
5, the level on calculated blasthole extended line and vertical coordinate movement value, compare the coordinate and plug-in of display
Coordinates computed, the error of the two meets precision when within 5%, that is, determines that it is practical layout point C (7 institutes in attached drawing 1
Refer to).
