[0042] Working principle:

[0043] When the deviation correction measurement of the pushing of the rectangular jacking pipe machine body 1, first, the first laser emission group 2, each transmission laser device 3 and the machine head receiving device 4 are horizontally aligned with the axis of the rectangular jacking pipe machine body 1 and the pipe joint, so when the second laser 22 on the first laser emission group 2 emits a laser beam to the left, it will be received by the photosensitive target assembly 33 adjacent to the first laser emission group 2, and the position of the light spot is analyzed and processed, and the photosensitive target assembly 33 analyzes and processes the obtained photosensitive target pattern and transmits it to the total station 5, which records the two-dimensional coordinate X / Y axis position of the laser beam on the target surface in real time, directly reflecting the horizontal and vertical deviation of the current position of the jacking pipe machine from the design axis.

[0044] It should be noted that when the photosensitive target plate 331 on the photosensitive target assembly 33 receives the laser beam emitted from right to left, the photosensitive target plate 331 is made of high transparent material and has the function of laser beam penetration, so the light source sensing film group 332 can sense the light intensity, and the wall thickness of the right groove wall of the sensing film pasting groove 3312 is designed to be 2mm, so that when the laser beam passes through the right groove wall of the sensing film pasting groove 3312 made of transparent material, the refraction of light can be controlled within a controllable range, but the light energy will be slightly reduced, but the reflective coating on the light guide plate 3322 can effectively reflect the light and transmit it to the photosensitive element plate 3321, so that the photosensitive element plate 3321 can realize light sensing, and the photosensitive element plate 3321 is composed of high-precision area array CCD / CMOS sensors, which has high sensitivity to light, and through the circuit processing and algorithm known technology design of the photosensitive element plate 3321, the two-dimensional coordinate X / Y axis position of the light spot on the photosensitive target assembly 33 can be obtained.

[0045] In addition, the photosensitive element plate 3321 is of high power type, and in order to ensure that the photosensitive element plate 3321 can work continuously under the condition of high humidity and heat in the underground jacking pipe, the heat accumulation will not affect the photosensitive accuracy and service life, so the left side of the photosensitive element plate 3321 is provided with a cooling fin 3323 and a cooling channel 334 for auxiliary cooling.

[0046] In order to ensure that the right side of the photosensitive target plate 331 is free of stains, and the cooling fin 3323 will fall dust and affect the cooling effect during long-term use, the present application also designs a photosensitive target cleaning assembly 34 to assist in processing, during cleaning, the mop block 343 is lifted on the vertical guide rail 341 by the slider 342, so that the brush strip 345 can lift and clean the dust on the left side of the cooling fin 3323, and the dust falls through the dust outlet 3313, and the scraping strip 344 lifts and scrapes the stains on the right side of the photosensitive target plate 331, in order to prevent the scraping strip 344 from being dry and causing scratches, a water spraying pipe 346 and a pressurized water storage tank 347 are also designed to assist in spraying.

[0047] The first laser emitting group 2, each transmission laser device 3, and the tilt meter 36 built-in on the head receiving device 4 synchronously collect the posture parameters of the rectangular pipe jacking machine main body 1, and the distance between the laser and the photosensitive target assembly 33 collected by the adjacent two distance measuring sensors is also transmitted to the total station 5, so that the total station 5 can assist in periodic review. The review operation of the total station 5 is prior art, and will not be described in detail here.

[0048] When detecting the levelness of the pipe joint, the corresponding first laser 35 and photosensitive target assembly 33 on the adjacent two transmission laser devices 3 need to be adjusted to a horizontal state for measurement. The horizontal deviation of the pipe joint is determined by the position of the light spot received by the photosensitive target assembly 33.

7. A measuring method using the rectangular top pipe automatic measuring device according to claim 6, characterized in that: The measurement method is as follows: When the propulsion deviation measurement of the rectangular pipe jacking machine body, first, the first laser emission group, each laser transmission device and the machine head receiving device are horizontally aligned with the axis of the rectangular pipe jacking machine body and the pipe joint, so when the second laser on the first laser emission group emits a laser beam to the left, it will be received by the adjacent light sensing target assembly to the first laser emission group to the light spot position and analyzed and processed, and the adjacent first laser of each laser transmission device and the machine head receiving device correspond to the light sensing target assembly in turn to the left, then the light sensing target assembly analyzes and processes the obtained light target pattern and transmits it to the total station, which records the two-dimensional coordinate X / Y axis position of the laser beam on the target surface in real time, directly reflecting the horizontal and vertical deviation of the current position of the pipe jacking machine and the design axis. The built-in inclinometer of the first laser emission group, each laser transmission device and the machine head receiving device synchronously collects the attitude parameters of the rectangular pipe jacking machine body, and the two adjacent distance sensors collect the distance between the laser and the light sensing target assembly, which are also transmitted to the total station, so that the total station can assist in periodic review. When detecting the levelness of the pipe joint, the corresponding first laser and light sensing target assembly on the adjacent two laser transmission devices need to be adjusted to the horizontal state for measurement, and the position of the light spot received on the light sensing target assembly is used to judge the level deviation of the pipe joint.
