1: Wu Dongde power station dome dam dam abutment groove width about 350m of example, high about 300m, excavation supporting is by 10m~15m
One bench is constructed, and three bench is dug under every month, the duration is very nervous, according to conventional forced centering concrete mark pier
Mode is completed since construction riding track does not excavate cleaning, is not only buried point and is difficult to choose, and the embedded period is long, at high cost, Wu Faman
The requirement of sufficient construction speed.By planning, the every lower digging about 50m of dam abutment divides the upstream and downstream of dam abutment slot on established bedrock surface
And left and right banks distinguishes this multiple device of Fast Installation, so that the total station in work surface can at least observe three or more this dress
It sets, realizes and set up the purpose of survey station and setting-out inspection, the basement rock excavation setting-out precision that specifications of surveys determines is ± 5cm, therefore instrument
Device is set up in front of this device within the scope of about 120 degree, can achieve this precision without arranging staff on duty to rotate prism,
So that the position that instrument is set up is very flexible, execute-in-place and cooperation are greatly facilitated, excavation construction pair is preferably met
The requirement of quality and progress.
2: Wu Dongde power station left bank underground power station transformer chamber of example is about 300m, wide 18.8m, height about 35m, main transformer
Room, auxiliary power house are frame layered arrangement, and structure is complicated, and the required precision of mirror surface engineering wall surface is high.According to plan, in transformer chamber left end
Wall, auxiliary power house right end wall upper layer and dike beam vertical wall install four this devices, and illuminator is installed by device, solve
The problem of underground engineering insufficient light.Since transformer chamber is sleeve configuration building, no matter instrument is set up in the where other than 50m,
In front of this device within the scope of about 20 degree, sight and work well, can guarantee to measure every time completely operating accuracy reach ± 5mm with
It is interior, and this device of once mounting is used in the entire construction time, therefore building overall precision is unified, metope is superior in quality,
Solve concrete mark pier nowhere bury and easily view obstruction and using layering on metope turn set general point control point accumulation miss
Poor big, precision deficiency problem.
Above-described embodiment is used to illustrate the utility model, rather than limits the utility model, practical at this
In novel spirit and scope of protection of the claims, to any modifications and changes that the utility model is made, this reality is both fallen within
With novel protection scope.
