In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: a total station prism combination device for opposite direction observation and quick orientation comprises a come card total station installed on a tripod, a small prism is arranged on the come card total station, and the small prism is located on the same axis with the come card total station through a positioning device.

In the preferred scheme, arrows are arranged on the periphery of a lens in the small prism, a level meter is arranged at the top of the lens, a clamping groove is formed in the bottom of the lens, and through holes are formed in the two sides of the clamping groove.

In the preferred scheme, a boss in the positioning device abuts against the clamping groove, and the boss is arranged at the top of the come total station.

In the preferred scheme, the small prism passes through the through hole through a bolt to be connected with the come card total station.

The utility model provides a total station prism composite set for subtend observation quick orientation, for two or more come card total station subtend orientation, install the small prism on come card total station through positioner guarantee higher precision, observe the spirit level and adjust the prism levelness, two come card total station subtend observation can solve and measure the problem that the structure has "dead angle", the efficiency of measuring in the process of the more structure measurement of local area has apparent improvement, directional control point and direction are the same two points, the position error of instrument lofting is greatly reduced, composite set can check the directional precision of measurement each other simultaneously, recheck through the comparison of two instrument directional errors, the error rate of measurement orientation is reduced, after composite set's orientation is accomplished, the sight is measured and will be intact observes the regional position that needs the measurement of positive film measuring instrument, will not need to set up repeatedly, the device has the advantages that the measurement error and efficiency are greatly improved, the procedure that the rearview prism is erected firstly and then the point position to be measured is measured, which is inherent to the staff in the ruler before measurement, is liberated, the staff in the ruler before measurement can directly place the point to be measured for measurement, the measurement efficiency is high, and the device can be used for checking whether the erected state of the instrument is stable in real time in the measurement process and quantitatively analyzing the eccentric error of the instrument erected for a long time.
