Embodiment Construction
[0031] Step 1, the gate 4 is placed flat on the site (the placement site of the gate 4 includes non-horizontal ground).
[0033] Step 3, in the gate 4 inner zone any line of sight position, set up a total station 5.
[0036]
[0042] Taking the No. 3 identification point as an example, the actual radius=SQRT[(193.9882-191.3695)
[0043] Step 7, the theoretical radius and the actual radius of the detection site 6 are different, and the error value obtained is used as the detection result.
[0046]
[0047]
[0051] 3. The problem of positioning detection of the three-dimensional gate in space is effectively solved, and the application is flexible and convenient.

The invention relates to a gate detection auxiliary tool and a gate flat roundness detection method, and belongs to the technical field of nuclear power plant construction. By setting up a total station at any viewing point inside the gate, and using the detection aids to cooperate, the three-dimensional measured coordinates of each detection point of the gate are measured; then the actual position coordinates of the gate center are calculated, the actual radius is converted, and the error value is obtained by comparison as the detection value. result. The invention solves the problem of checking the size and quality of the gate in the horizontal state, not only can obtain accurate detection results, but also provide a basis for the adjustment of the actual position, but also the frame station is flexible, the measurement is convenient, does not occupy the space of other construction processes, and is helpful for To meet the needs of construction progress optimization.
Description
A kind of gate detection auxiliary tool and gate flat roundness detection method technical field The invention belongs to the technical field of nuclear power plant construction, and relates to nuclear reactor plant equipment gates, personnel gates and emergency The detection of a gate specifically relates to an auxiliary tool for gate detection and a method for detecting the flatness roundness of the gate. Background technique [0002] The gate of the nuclear reactor building is a circular steel sleeve with a radius of 8400, 8300, 7400, 4300, 3650, 2650 and other specifications, the facade is an arc with the same radius as the containment of the reactor building, and the roundness is important for the final sealing of the containment. Energy is extremely important, the function of the gate is the passage of large equipment, and during the construction period, it is the passage of equipment in the factory building. during operation In a closed state, it is used about ...
