Embodiment
Structure of the present utility model is shown in Fig. 1-2: verticality and height datum pick-up unit in the slding form operation of a kind of deep-well buildings, comprise a back up pad 2, back up pad 2 one ends are fixed on the rock face 8, bracing frame 1 one ends are connected with back up pad 2, the other end is fixed on the rock face 8, in back up pad 2 capstan 3 is installed, capstan 3 centers are provided with bearing 9, back up pad 2 bottoms are equipped with prism 4 and guiding red light 11, weight 7 is connected with steel wire 5, the pilot hole 10 that steel wire 5 passes on the back up pad 2 is connected with capstan 3, and weight 7 places oil drum 6.
Described prism 4 is the sphere prism greater than the 8cm diameter.
Described steel wire 5 is the finer wire less than 1mm.
Installation of the present utility model and testing process are as follows:
During installation, the bracing frame 1 usefulness bolt that will adopt the 5cm angle bar to make earlier fixedly secures at the vertical shaft well head to be treated on the rock face 8 of lining cutting, bracing frame 1 should stretch out the enough length of well head, again the thick iron plate of 1cm is welded on the bracing frame 1 as back up pad 2, install and fix capstan 3 in back up pad 2, put to the operation platform of shaft bottom template mouth with capstan 3 after finer wire 5 on the capstan passes the pilot hole that diameter on the back up pad 2 is 3mm being entangled in advance, little iron hoop on the hook on the weight 7, utilize capstan about in the of 3 the scrolling adjustment weight 7 is all immersed in the oil drums 6 but at the bottom of not touching barrel or the bucket wall.Install reflecting prism 4 and guiding red light 11 in the screw of the 1cm diameter that on iron plate, has bored downwards, the installation of this device.
In this device, bracing frame 1 is the 5cm angle bar, guarantees the firm unshift sedimentation of whole device in the long construction time, bearing 9 is installed at capstan 3 centers, and smooth and easy when making scrolling, prism 4 is the sphere prism greater than the 8cm diameter, can reflect the multiaspect laser beam, guarantee distance accuracy.Steel wire is less than the 1mm finer wire, and weight weight guarantees that greater than 8kg there are enough collimation in system.Device is installed and used in the process and will regularly be checked, guarantees not have and damages non-displacement.
When utilizing this device to measure, generally at the borehole wall of roughly crossing the well head center of circle this device of two covers is installed, by the planimetric coordinates of two steel wires of fourth class control survey precision determination and the elevation at prism center.Be the device detection plane figure of place, shaft bottom as Fig. 3, Fig. 4 is for detecting sectional view.The vertical shaft template is for reinforcing the unitary whole template; before the sliding liter of sliding formwork; to install to settle and put in place; directly measure steel wire to the size of each template mouth record and mark as the initial baseline value; then can utilize capstan 3 in the sliding formwork cunning when rising; by crank 12 steel wire 5 and weight 7 are carried at any time, measured steel wire at any time with aforementioned identical way and compare apart from template mouth size and initial baseline value, thereby detect the verticality that vertical shaft is constructed at any time.For preventing template local deformation in construction, can regularly go into the well, relative position to two steel wires checks its phase position with long steel ruler earlier, behind the affirmation system non-displacement, utilize two steel wire coordinates to determine total powerstation 13 coordinates, just can carry out planimetric coordinates to each unique point position of template mouth and detect, and work out regular detection data.Utilize the diagonal eyepiece of instrument under the guide of well head pick-up unit guiding red light, to sight reflecting prism 4 simultaneously, measure the discrepancy in elevation and determine the elevation at total powerstation center, just can detect metal construction embedded part center, down-hole elevation, and can demarcate elevation at support bar, as the height datum use of slding form operation.
This device is owing to adopt thin less than the steel wire of 1mm, weight weight is bigger, and immerse the oil drum transfixion when using, enough verticality (can reach 1/60000) and steady state (SS) have been guaranteed, error when verticality measures is mainly measures steel wire to the steel ruler reading error of template mouth, therefore measure apart from the time note the tight template of steel ruler one end card motionless, an end aim at steel wire slide up and down read minimum number can make reading accuracy reach ± 3mm in.Vertical error is mainly derived from the instrument range error, and what we used is that precision index is the total powerstation of 2mm+2ppm, considers complex environment in the well, and the elevation measurement accuracy can reach ± 5mm.
