[0043] Embodiment 1

[0045] Step 1: Two centering brackets 1 are fixed at positions on the vertical side caps of the bridge pier, a high-precision laser plumb line is set up to project an upward plumb line visible light, and the pier top bracket 2 is adjusted to determine the laser receiving center on the bracket;

[0046] Step 2: Set up an automatic collimator total station to aim at the pier top prism, measure the vertical pier height, calculate the pier top elevation, deduce the position of the slope change template, adjust the slope change template to the appropriate position according to the positioning line, and the vertical prism placed on the pier top bracket 2 can be checked with the total station for plane coordinates and elevation.

[0047] Two long level bubbles are fixed on the centering bracket 1. The lower leveling device can level the top surface of the bracket. When it is adjusted to a fixed position, it can be fixed firmly with expansion bolts.

[0048] The centering bracket 1 can be equipped with a laser plumb line, a total station, a prism rod or an elevation rod to measure the plane coordinates and elevation of the fixed position of the centering plate. The laser plumb line has a vertical measurement standard deviation of ≤1 / 45000 for one round upward, a long level angle of 20" / 20m, an effective laser range of ≥200m during the day and ≥300m at night; the laser spot is ≤3mm / 50m;

[0049] When measuring height with a precision total station, remove the handle, measure the air pressure and temperature at the instrument and the pier top, and take the average value and input it into the instrument.

[0050] The pier top bracket 2 is placed in a fixed position on the slope changing template. The slope changing template is adjusted so that the center position of the laser receiving target coincides with the position of the centering bracket 1 on the pedestal, and the vertical collimator can be rotated at four angles to check the deviation.

[0051] Specific measurement methods and implementation methods:

[0052] 1. Control standards

[0053] There is no clear stipulation on the construction control standard of super-high piers in the existing construction specifications. Refer to the acceptance allowable deviation standard of main towers of cable-stayed bridges and suspension bridges: cross-sectional dimension ±20mm, inclination 1 / 3000 of the pier height and no more than 30mm.

[0054] 2. Use laser plumb line to measure the position of the cross section plane

[0055] (1) Introduction to laser plumb line: DZJ30 laser plumb line produced by Suzhou Yiguang Co., Ltd., main technical parameters: standard deviation of upward plumb line measurement 1 / 45000; effective laser range ≥100m during the day, ≥250m at night; equipped with a wooden tripod, manual leveling, and laser beam downward alignment.

[0056] (2) Setting the center point of the laser plumb line

[0057] The cap of Pier No. 6 of Pengyuangou Bridge is located 50cm outward from the axis along the pier body, and 8 points are set at the four corners of each hollow pier along the longitudinal and transverse directions away from the pier body (the coordinates of the 8 control points are calculated according to the design coordinates of the line center, and the stakeout is conducted after multiple levels of review). The laser plumb line is placed on the axis of the control point, and the downward laser beam button is activated to make the position of the laser plumb line level with the center of the stakeout control point, and fixed with expansion screws.

[0058] (3) Cut a 20×20 square hole (grid laser target size is 20×20 cm) at the corresponding position on the pedestrian walkway on the top surface of the pier, and install the laser target on this hole. Install the angle bracket on the centering bracket 1, install the laser plumb line, turn on the button to launch the laser beam upward, roughly center and roughly level, center and accurately level the laser plumb line again. Turn off the downward launch button, turn on the upward launch button, adjust the focal length of the objective lens, so that the laser beam forms a light spot with a diameter of 1 mm on the target, mark the center of the light spot on the upper surface of the target, and rotate the laser plumb line horizontally at will to see whether the center deviation of the light spot exceeds 1 mm multiple times. If it exceeds, readjust the plumb line until the center deviation of the light spot does not exceed 1 mm multiple times. At this time, the vertical line of the laser beam is the vertical direction line of the control point.

[0059] (4) Use a total station in conjunction with the vertical prism on the pier top bracket 2 to measure the height of the bridge pier. The verticality angle = arctan (height difference / reference distance) is measured based on the height difference of the bridge piers between multiple total stations.

[0060] See also Figures 3 to 13 A measuring mechanism 3 is detachably installed on the outside of the pier top bracket 2 and located on the pier top.

[0062] Specifically: when installing the measuring mechanism 3, the connecting shell 322 is installed according to the position of the pier top, that is, when installing the connecting shell 322, the two side plates 31 can be extended to the outside of the pier top, so as not to affect the wind force and temperature detection of the measuring component 5, and during installation, the relative position between the connecting plate 321 and the connecting shell 322 can be adjusted, and then, by tightening the locking bolt 325, the support length of the connecting plate 321 and the connecting shell 322 can be adjusted, and then the connecting shell 322 can be stably fixed on the pier top by the fixing bolt 324.

[0063] See also Figure 6 to Figure 7The two ends of the support shaft 33 are rotatably connected to the two side plates 31 through bearings, and the winding sleeve 34 is fixedly sleeved on the outside of the support shaft 33. In this embodiment, the winding sleeve 34 is in an I shape, and its two ends can play a role in limiting the connection rope 37 and the measuring member 5. The locking mechanism 35 and the rotating member 36 are respectively located at the two ends of the support shaft 33, and the locking mechanism 35 is located at one of the side plates 31. The locking mechanism 35 is used to lock the winding sleeve 34;

[0064] One end of the connecting rope 37 is fixedly connected to the winding sleeve 34, and the other end of the connecting rope 37 is fixedly connected to the gravity ball 38;

[0065] There are multiple measuring pieces 5 , and the multiple measuring pieces 5 are distributed on the connecting rope 37 at equal distances.

[0066] See also Figure 5 to Figure 6 The telescopic connecting member 32 includes a connecting plate 321, a connecting shell 322, a connecting ear 323, a fixing bolt 324 and a locking bolt 325. The side plate 31 is fixedly mounted on the top of the connecting plate 321. One end of the connecting plate 321 is slidably connected to the inside of the connecting shell 322. The locking bolt 325 is rotatably connected to the connecting shell 322, and the locking bolt 325 is used to lock the connecting plate 321.

[0067] There are two connecting ears 323, which are fixedly installed on both sides of the connecting shell 322. There are multiple fixing bolts 324. The connecting ears 323 are provided with connecting holes at positions corresponding to the fixing bolts 324, and the connecting ears 323 are detachably installed on the pier top through the fixing bolts 324. A reinforcing rod 326 is installed on the outside of the connecting plate 321, and the reinforcing rod 326 is fixedly connected to the side plate 31.

[0068] See also Figure 5 to Figure 6 The locking mechanism 35 includes a locking ring 351, a locking screw 352, a handle 353 and a threaded sleeve 354, wherein a through hole is provided at a position corresponding to the locking screw 352 on one of the side plates 31, and the locking screw 352 passes through the through hole, and a side of the locking screw 352 close to the winding sleeve 34 is rotatably connected to the locking ring 351, and the locking ring 351 is slidably sleeved on the outside of the support shaft 33, and a locking groove 341 is provided on a side of the winding sleeve 34 corresponding to the locking ring 351;

[0069] The threaded sleeve 354 is located outside the through hole and fixedly mounted on the side plate 31 , and the locking screw 352 is threadedly connected to the threaded sleeve 354 .

[0070] Specifically, when the connecting rope 37 is lowered to the outside of the bridge pier by the gravity ball 38, and under the connecting action of the gravity ball 38, the connecting rope 37 is relatively stably distributed on the outside of the bridge pier, then, by rotating the handle 353, the locking screw 352 is rotated relative to the side plate 31, and when the locking screw 352 rotates, the locking ring 351 is limited by the support shaft 33, and then the locking ring 351 moves along the winding sleeve 34 until the locking screw 352 is locked. One side of the ring 351 abuts against the locking groove 341 on one side of the winding sleeve 34, so that the locking ring 351 can lock and fix the winding sleeve 34 to prevent the winding sleeve 34 from rotating relative to each other. At the same time, when the winding sleeve 34 winds up the connecting rope 37 and the measuring piece 5, the locking ring 351 abuts against the locking groove 341, so that the winding sleeve 34 can be fixed relative to the side plate 31, thereby achieving the function of storing the connecting rope 37.

[0071] See also Figure 11 to Figure 12 The measuring member 5 includes a support tube 51, a limiting ring 52, a support block 53, an air guide mechanism 54, a proximity sensor 55, a counter 56 and a temperature sensor 57. The support tube 51 is fixedly sleeved on the outside of the connecting rope 37. Two limiting rings 52 are provided. The two limiting rings 52 are fixedly mounted on both ends of the support tube 51 respectively.

[0072] The support block 53 is rotatably sleeved on the outside of the support tube 51. The support block 53 is provided with a plurality of inclined surfaces 531. In this embodiment, the support block 53 is a conical pile, and three inclined surfaces 531 are provided. The three inclined surfaces 531 are arranged around the support block 53. A plurality of air guide mechanisms 54 are provided. The plurality of air guide mechanisms 54 are respectively installed on the inclined surfaces 531. A groove 532 is provided at the bottom of the support block 53. The groove 532 is located on the outside of the support tube 51.

[0073] The proximity sensor 55 is fixedly mounted on the support tube 51 and is located inside the groove 532 , and a proximity block 58 is mounted on the support block 53 and located at the groove 532 ;

[0074] See also Fig.13 The proximity sensor 55 is electrically connected to the controller 59 , and the controller 59 is electrically connected to the counter 56 , and the controller 59 is electrically connected to the alarm element 4 . The temperature sensor 57 is fixedly mounted on the support tube 51 and is located inside the groove 532 .

[0075] The air guide mechanism 54 includes an arc plate 541 and an arc piece 542. There are multiple arc pieces 542.

In this embodiment, the multiple arc plates 541 form a spherical shape, so that the multiple air guide mechanisms 54 can be stored conveniently through the connecting rope 37, which is convenient for measurement and use.

[0076] Specific implementation process: In order to prevent the bridge pier from swinging due to the influence of temperature and wind force during the verticality detection of the high pier of the bridge, thereby affecting the detection of the laser vertical leveler and the total station, a plurality of measuring pieces 5 are placed on the outside of the pier through the gravity ball 38, and since the air guide mechanism 54 is composed of a plurality of arc pieces 542 and an arc plate 541, when the wind force is detected, the airflow in different directions enters the irregular space formed between the arc plate 541 and the inclined surface 531 along the arc piece 542, and is affected by the wind force. The arc plate 541 causes the conical support block 53 to rotate relative to the support tube 51 through the arc piece 542. At this time, the support block 53 and the plurality of arc pieces 542 outside it rotate relative to the support tube 51. The support block 53 rotates synchronously with respect to the support tube 51. When the support block 53 rotates, the proximity block 58 at the inner groove 532 thereof rotates relative to the proximity sensor 55 on the support tube 51. The proximity sensor 55 sends a value to the controller 59. The controller 59 sends a signal to the counter 56. The controller 59 determines the rotation speed of the support block 53 according to the signal sent by the counter 56 within a certain period of time. When the rotation speed is high, the wind force is high. At this time, the buzzer 41 warns. At this time, the signal errors detected by the laser vertical collimator and the total station are large. Similarly, when the temperature is low or high, the buzzer 41 warns. At this time, the signal errors detected by the laser vertical collimator and the total station are large.

[0077] Only when the rotation speed of the multiple support blocks 53 is slow and the signal value detected by the temperature sensor 57 is within the set range, the laser plumb line and the total station can be used to detect the verticality of the bridge pier.
