Abstract
The invention discloses a distributing method and structure of GPS control points of a water delivery line in a mountain area outside a tunnel hole. The distributing method is characterized in that six GPS control points (2, 3, 4, 5, 6 and 7) are distributed on a tunnel inlet and a tunnel outlet of a water delivery tunnel (1), wherein three control points are located at the tunnel inlet, the other three control points are located at the tunnel outlet, and the height difference of the control points is within 30m; the three control points at the tunnel inlet are distributed in an equilateral triangle manner, and the three control points at the tunnel outlet are also distributed in an equilateral triangle manner. The method can overcome the limitation that traditional measurement control cannot meet a tunnel control requirement, can well ensure the measurement precision and the accurate penetration of the tunnel, is mainly suitable for distribution of the control points outside the water delivery tunnel, can meet the distributing requirement of the control points outside the tunnel by virtue of the points only, and can greatly reduce the expense.
Description
Technical field
The present invention relates to distribution method and the structure at the outer GPS reference mark of a kind of Tunnel based on mountain area water delivery line, belong to earth observation and field of navigation technology.
Background technology
In recent years, southwest such as the investment of water project in the provinces such as Guizhou strengthened, and big-and-middle-sized mountain area hydraulic engineering quantity is greatly improved, and the technology of relevant hydraulic engineering construction is also maked rapid progress.Wherein, mapping is the basis of engineering construction, only has acquisition basic data, and design effort just can be carried out.And along with the enforcement of a large amount of water project, project is many, it is urgent that time is pressing, the difficulties such as task amount is huge are also following, if the mapping operations in early stage conventionally completing these engineerings is impossible substantially, therefore risen now and adopted GPS means to carry out the technology of mapping operations, large for long distance water transfer Control networks for lines coverage, trees are many at reference mark, net type is complicated, and rationally solve the joining relation of construction control network and state control net and mapping Controling network, gradually with regard to the laying of GPS Controling network, observation time, period, data processing, the realization of high precise control net in engineering, this wherein, a lot of difficulty is also existed to the GPS mapping of the province alpine terrains such as Guizhou, because there is singularity in the landform in these areas, as high mountain and steep gorge area, satellite-signal blocks very serious, high precision to be reached in such place, speed is very difficult soon, place (topographic condition is just more serious) particularly residing for water conservancy and hydropower project.Therefore, prior art is still perfect not.
Summary of the invention
The outer ground of a kind of Tunnel is the object of the present invention is to provide to control to carry out the location survey benchmark (space orientation) of planimetric position and elevation, the namely distribution method at the outer GPS reference mark of the Tunnel of mountain area water delivery line and structure, to overcome the deficiencies in the prior art.
For realizing object of the present invention, the distribution method at the outer GPS reference mark of Tunnel of a kind of water delivery line of the present invention, tunnel entrance wherein in water tunnel and tunnel exit lay six GPS reference mark, wherein three reference mark are positioned at tunnel entrance, other three reference mark are positioned at tunnel exit, and the discrepancy in elevation between each reference mark is within 30m; Three reference mark of tunnel entrance are pressed equilateral triangle and are arranged, three reference mark of tunnel exit are also pressed equilateral triangle and arranged.
Based on the GPS control points layout structure for water tunnel of said method, comprise water tunnel, wherein be provided with reference mark A, reference mark B and reference mark C in the inflow point of water tunnel, be provided with reference mark D, reference mark E and reference mark F in the exit of water tunnel, the discrepancy in elevation between each reference mark is within 30m; Reference mark A, reference mark B and reference mark C are each other in equilateral triangle, and reference mark D, reference mark E and reference mark F are each other in equilateral triangle.
Further, aforesaid reference mark B is laid near the extended line of import and export line of water tunnel, and be not less than 300m apart from tunnel entrance, the left and right that aforesaid reference mark A and reference mark C is laid in tunnel entrance is respectively not less than 150m place far from tunnel center line.
Accordingly, aforesaid reference mark F is laid near the extended line of import and export line of water tunnel, and be not less than 300m apart from tunnel exit, the left and right that aforesaid reference mark D and reference mark E is laid in tunnel exit is respectively not less than 150m place far from tunnel center line.
Owing to have employed technical scheme of the present invention, overcome the limitation that traditional Survey control can not meet tunnel control, measuring accuracy can be ensured well simultaneously, ensure the correctly through of tunnel, control points layout outside the hole being mainly applicable to water tunnel, only can meet the laying requirement at the outer reference mark of Tunnel with 6 points, greatly reduce expense.
