Embodiment 1
[0032] A multi-point spatial positioning method for super-long rods, including post-anchor beam positioning measurement and anchor rod positioning measurement, such as image 3 , Figure 5 As shown, the rear anchor beam 1 is positioned and installed on the rear bracket 4, and the anchor rod 5 is positioned and installed on the rear anchor beam 1, the middle bracket 6 and the front bracket 7; as figure 1 , figure 2 , Figure 4As shown, the rear anchor beam 1 is provided with several anchor brackets 2 along the axial direction, and the anchor bracket 2 is provided with several high bolt holes 3 arranged in an array, along the axis of the rear anchor beam 1 Select any pair of high-bolt holes 3 on the outermost sides of the anchor bracket 2 at the two ends and the middle in the direction of direction as the high-bolt hole measurement point 31 of the rear anchor beam, and measure the spatial coordinates of the high-bolt hole measurement point 31 after positioning Spatial positi...
Embodiment 2
[0034] Based on the above-mentioned embodiment 1, such as Figure 5 , Figure 6 As shown, the upper surface of the anchor rod 5 along the axial direction is provided with upper, middle and lower three sections, and each section is provided with a measuring point, and the lower section is located on the anchor corbel on the rear anchor beam. 2. At the connection point, the middle section is located in the middle of the anchor rod, and the upper section is located at the end of the unconnected anchor bracket of the anchor rod; the lower section is symmetrically provided with a pair of lower section measurement points 51, and the middle A pair of mid-section measurement points 52 are arranged symmetrically on the section, and a pair of upper section measurement points 53 are symmetrically arranged on the upper section. A pair of upper section measurement points 53 and the upper section middle measurement point 531 arranged symmetrically are on the same straight line and are perp...
Embodiment 3
[0036] Based on the above-mentioned embodiment 1, such as Figure 1-4 As shown, the positioning measurement of the rear anchor beam comprises the following steps:
[0037] 1) Set a space position corresponding to the size of the rear anchor beam on the rear bracket 4
[0038] 2) hoisting the rear anchor beam 1 on the spatial position of the rear bracket 4, and initially fixing the rear anchor beam 1;
[0039] 3) Use a total station to measure the high bolt hole measurement point 31 of each rear anchor beam 1, measure the local space coordinates X, Y and Z of each high bolt hole measurement point 31, and the local space coordinate system is as follows Figure 7 shown;
[0040] 4) Adjust the spatial position and linearity of the rear anchor beam 1 according to the deviation between the measurement data of each high-bolt measurement point 31 and the theoretical data designed for the high-bolt hole measurement point 31 by the total station.
[0041] In this embodiment, the rear...
