[embodiment]
Below in conjunction with accompanying drawing, the invention will be further described, and the structure of this device and principle are very clearly concerning this professional people.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Embodiment 1
As shown in Figure 1, a kind of upper pipe working well plane connection survey, comprise Laser plumb instrument and forced centering device, plane connection survey is as follows: between two wells, set up geodetic quadrangle coordinate system, by forced centering device under active well, lay the glass plate center of the band rice lattice of laying at Laser plumb instrument projecting laser to aboveground travel(l)ing rest place, by near-shaft control point, measure glass plate centre coordinate and determine down-hole position coordinate.
The Kunming tail water of take is arranged pipe-jacking project outward as example, it is one of Kunming Dianchi lake waste water treatment project that Kunming tail water is arranged pipe-jacking project outward, establishing 11 active wells divides 10 sections of jacking circuits completely, wherein the longest section 11# well-12# well top, top section total length is 1.2 kilometers, belong to extra long distance jacking construction, during due to push pipe jacking construction, tube coupling is along with the extension of top section is followed up, and is to belong to kinetic measurement, and necessary unidirectional jacking is to the well of appearing, higher to the accuracy requirement of tunnel survey.Every pipe joint joint is from calling in, and being installed to out top has the vacant time of 2 hours to measure in real time, and classic method can not guarantee to complete connection survey within the limited time, therefore adopt this method to carry out.
Pipe-jacking project requires the relatively independent precision of two wells very high, therefore propose to adopt quadrilateral, control net, not adopting triangle is to check condition for increasing by one, guarantee to control the relative accuracy of net, shaft plumbing adopts triangle to hang steel wire method when adopting the method and compares, thereby further determine the relative merits of this method, precision, time etc.
