AI Technical Summary
Existing technologies for surveying the foundation slab of steeply inclined corridors suffer from problems such as low accuracy, low efficiency, high labor input, and poor operability. In particular, conventional surveying methods are difficult to achieve accurate elevation control and rapid surveying during the construction of the foundation slab of steeply inclined corridors.
The plane coordinates and elevation of the top of the elevation pile are measured using a total station. Combined with a programming calculator program, the correction value δ is calculated and marked using the formula (δ=Z0+(X-X0)×tg(α)-Z pile or δ=Z0+(Y-Y0)×tg(α)-Z pile), thus achieving rapid and accurate determination of the top surface point of the base plate.
It improves the accuracy and efficiency of surveying the bottom slab of steep-angle corridors, simplifies the measurement steps, reduces human calculation errors, and makes it convenient to measure on slopes and planes, thus enhancing the practicality and flexibility of the method.
