Description
Technical Field
[0001] The present invention relates to the technical field of municipal engineering, and in particular to a laser deformation monitoring device and a deformation monitoring method. Background Art
[0002] With the development of infrastructure construction, a large number of engineering construction projects are located around important infrastructure, such as highways, high-speed railways and ordinary railways. During the construction process, the construction of surrounding projects may cause deformation of the ground where important infrastructure such as highways are located, which may lead to the suspension and closure of these important infrastructures, causing a great impact on normal transportation. Therefore, it is necessary to strictly protect and monitor the deformation of the ground where these important facilities are located during the construction process.
[0003] Since expressways, high-speed railways and ordinary railways need to be in operation all the time, it is difficult for operators to set up measurement points on the surface of these facilities, and conventional monitoring methods are difficult to monitor the deformation of the ground where these important facilities are located. Existing high-tech measurement methods such as intelligent and digital are expensive, and the feasibility and accuracy of the measurement data are difficult to verify. Summary of the invention
[0004] The technical problem to be solved by the present invention is to overcome the defect in the prior art that the ground deformation of infrastructure such as highways, high-speed railways and ordinary railways is difficult to measure, and to provide a laser deformation monitoring device and a deformation monitoring method.
[0005] The present invention solves the above technical problems through the following technical solutions:
[0006] The present invention provides a laser deformation monitoring device, which includes a measuring tube, a laser transmitter, a measuring plate and a recording device. The measuring tube is used to be arranged below a measured object, and the laser transmitter is used to transmit light from a laser transmitting point to a laser receiving point. The laser transmitting point is arranged near one end of the measuring tube, and the laser receiving point is arranged near the other end of the measuring tube. The spatial coordinates of the laser transmitting point and the laser receiving point are fixed and unchanged.
[0007] A plurality of measuring plates are arranged inside the measuring tube, the light emitted by the laser emitter can be irradiated on the measuring plates, the measuring plates are made of light-transmitting materials, and the recording device can record the position of the light emitted by the laser emitter on the measuring plates.
[0008] In this solution, the measuring tube is arranged below the measured object, the laser transmitter is used to transmit light from the laser transmitting point to the laser receiving point, and the measuring plate is arranged inside the measuring tube and is a light-transmitting material, so that the light emitted by the laser transmitter can pass through the measuring plate and irradiate the laser receiving point. Since the spatial coordinates of the laser transmitting point and the laser receiving point are fixed, the position of the light emitted by the laser transmitter remains unchanged. When the measuring tube is deformed, the position of the measuring plate fixed inside the measuring tube will also change accordingly, and the position of the light emitted by the laser transmitter on the measuring plate will change. Therefore, the deformation of the measuring tube can be obtained by recording the position of the light emitted by the laser transmitter on the measuring plate through a recording device. The deformation of the measuring tube can be used to know the deformation of the measured object, and there is no need to monitor the surface of the measured object, which solves the problem that the measured object itself is difficult to monitor.
[0009] Preferably, an extending direction of the measuring tube is consistent with an extending direction of the measuring object.
[0010] In this solution, by setting the extension direction of the measuring tube to be consistent with the extension direction of the measured object, it is more conducive to reflecting the deformation of the measured object on the deformation of the measuring tube, making the measurement of the laser deformation monitoring device more accurate.
[0011] Preferably, the measuring tube extends in a horizontal direction.
[0012] In this solution, since the measured object usually extends in the horizontal direction, by extending the measuring tube in the horizontal direction, the measuring tube can better respond to the deformation of the measured object in the vertical direction, making the laser deformation monitoring device more accurate in measurement.
[0013] Preferably, an extending direction of the light emitted by the laser emitter is consistent with an extending direction of the measuring tube.
[0014] In the present solution, by aligning the extension direction of the light emitted by the laser emitter with the extension direction of the measuring tube, it is easier to locate the position of the light on the measuring plate, which is convenient for operators to record and calculate. It is also easier for the light emitted by the laser emitter to reach the laser receiving point from the laser emitting point, thereby avoiding the situation in which the measuring tube blocks the irradiation path of the light after the measuring tube is deformed, resulting in the light not being able to reach the laser receiving point.
[0015] Preferably, the upper end of the measuring plate is suspended on the inner surface of the measuring tube.
[0016] In this solution, the upper end of the measuring board is suspended on the inner surface of the measuring tube so that the measuring board can always remain in a vertical state, making it easier for the light emitted by the laser transmitter to irradiate the measuring board and for the operator to record the laser point position.
[0017] Preferably, the measuring plate has a graduated scale.
[0018] In this solution, by setting a scale ruler on the measuring plate, the position of the laser point on the scale plate can be better located, making it easier for operators to record the laser point.
[0019] Preferably, the recording device is a camera device, which can move along the extension direction of the measuring tube, and is used to record the position of the light emitted by the laser emitter on the measuring plate.
[0020] In this solution, the recording device is a camera, which can move along the extension direction of the measuring tube, so that the camera can record the measuring plate at different positions in the extension direction of the measuring tube. According to the laser point position on the measuring plate, the deformation conditions at different positions in the extension direction of the measuring tube can be known, and the deformation monitoring of the measured object is more comprehensive.
[0021] Preferably, a slide rail is provided inside the measuring tube, the extension direction of the slide rail is consistent with the extension direction of the measuring tube, and the camera device can slide along the slide rail.
[0022] In this solution, a slide rail is provided inside the measuring tube, and the camera device can slide along the slide rail. The extension direction of the slide rail is set to be consistent with the extension direction of the measuring tube, so that the camera device can move in the extension direction of the measuring tube. The movement of the camera device is more convenient by setting the slide rail.
[0023] Preferably, the laser deformation monitoring device further comprises a traction member, and the traction member is connected to the camera device.
[0024] In this solution, by providing a traction member connected to the camera device, the operator can move the camera device on the slide rail by pulling the traction member, thereby making it easier for the operator to change the position of the camera device.
[0025] The present invention also provides a deformation monitoring method, which is implemented by using the laser deformation monitoring device and includes the following construction steps:
[0026] constructing a hole under the surface of the measurement object using a drill bit;
[0027] inserting the measuring tube into the borehole;
[0028] injecting a fixing material between the borehole and the measuring tube to fill a gap between the borehole and the measuring tube;
[0029] At different time points, light is emitted from the laser transmitter and received by the laser receiving point;
[0030] Recording the position of the light emitted by the laser emitter on the measuring plate at different time points by the recording device;
[0031] The positions of the light emitted by the laser emitter on the measuring plate at different time points are compared to obtain the deformation of the surface of the measuring object.
[0032] In this scheme, a borehole is first constructed under the surface of the measured object, and a measuring tube is inserted into the borehole, so that the measuring tube is set below the measured object, and then a fixing material is injected between the borehole and the measuring tube to fill the gap between the borehole and the measuring tube, so that the measuring tube can be more stably fixed in the borehole. At different time points, the laser transmitter emits light from the laser emission point to the laser receiving point, and the recording device records the position of the light emitted by the laser transmitter on the measuring board at different time points. By comparing the position of the light emitted by the laser transmitter on the measuring board at different time points, the deformation of the measuring tube can be known, and then the deformation of the surface of the measured object can be obtained through the deformation of the measuring tube, without the need to monitor the surface of the measured object, which solves the problem that the measured object itself is difficult to monitor.
[0033] The positive and progressive effects of the present invention are:
[0034] The present invention provides a laser deformation monitoring device, which includes a measuring tube, a laser transmitter, a measuring plate and a recording device. The measuring tube is arranged below the measured object, and the laser transmitter is used to transmit light from the laser transmitting point to the laser receiving point. Since the spatial coordinates of the laser transmitting point and the laser receiving point are fixed, the position of the light emitted by the laser transmitter remains unchanged. When the measuring tube is deformed, the position of the measuring plate fixed inside the measuring tube will also change accordingly, and the position of the light emitted by the laser transmitter on the measuring plate will change. Therefore, the deformation of the measuring tube can be obtained by recording the position of the light emitted by the laser transmitter on the measuring plate through the recording device. The deformation of the measuring tube can be used to know the deformation of the measured object, and there is no need to monitor the surface of the measured object, which solves the problem that the measured object itself is difficult to monitor.

[0059] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the following examples.
[0060] like Figure 1-Figure 5As shown, this embodiment provides a laser deformation monitoring device 200, which includes a measuring tube 210, a laser emitter 220, a measuring plate 230 and a recording device 240. The measuring tube 210 is used to be arranged below the measured object 100, and the laser emitter 220 is used to emit light 340 from a laser emitting point 310 to a laser receiving point 320. The laser emitting point 310 is arranged near one end of the measuring tube 210, and the laser receiving point 320 is arranged near the other end of the measuring tube 210. The spatial coordinates of the laser emitting point 310 and the laser receiving point 320 are fixed. The spatial coordinates here refer to coordinates that are fixed in geographic space, and the spatial coordinates can be determined by standard measurement mark points. A plurality of measuring plates 230 are arranged inside the measuring tube 210. The light 340 emitted by the laser emitter 220 can be irradiated on the measuring plates 230. The measuring plates 230 are made of light-transmitting materials, so that the light emitted by the laser emitter 220 can pass through the measuring plates 230 and irradiate on the laser receiving point 320. The recording device 240 can record the position of the light 340 emitted by the laser emitter 220 on the measuring plates 230.
[0061] Since the spatial coordinates of the laser emission point 310 and the laser receiving point 320 are fixed, the position of the light 340 emitted by the laser emitter 220 remains unchanged. When the measuring tube 210 is deformed, the position of the measuring plate 230 fixed inside the measuring tube 210 will also change accordingly, and the position of the light 340 emitted by the laser emitter 220 on the measuring plate 230 will change. Therefore, the deformation of the measuring tube 210 can be obtained by recording the position of the light 340 emitted by the laser emitter 220 on the measuring plate 230 through the recording device 240. The deformation of the measuring tube 210 can be further known by the deformation of the measuring object 100, without the need to monitor the surface of the measuring object 100, which solves the problem that the measuring object 100 itself is difficult to monitor.
[0062] During the construction of infrastructure such as highways, high-speed railways and ordinary railways, the measurement object 100 is usually the ground. Usually, only deformation of the underground can cause deformation of the ground. By setting the measuring tube 210 underground, the deformation of the underground can be reflected, and then the deformation of the ground can be known.
[0063] In this embodiment, the measuring plates 230 are evenly spaced and arranged along the extending direction of the measuring tube 210. In other embodiments, other arrangements of the measuring plates 230 that are considered appropriate by those skilled in the art may also be selected.
[0064] The extension direction of the measuring tube 210 is consistent with the extension direction of the measuring object 100, which is more conducive to reflecting the deformation of the measuring object 100 on the deformation of the measuring tube 210, making the measurement of the laser deformation monitoring device 200 more accurate.
[0065] Since the measured object 100 usually extends in the horizontal direction, in this embodiment, the measuring tube 210 extends in the horizontal direction, so that the measuring tube 210 can better reflect the deformation of the measured object 100 in the vertical direction, making the laser deformation monitoring device 200 measure more accurately. In other embodiments, other extending directions of the measuring tube 210 that are considered appropriate by those skilled in the art may also be selected.
[0066] The extension direction of the light 340 emitted by the laser emitter 220 is consistent with the extension direction of the measuring tube 210, which makes it easier to locate the position of the light 340 on the measuring plate 230, facilitates the operator to record and calculate, and also makes it easier for the light 340 emitted by the laser emitter 220 to reach the laser receiving point 320 from the laser emitting point 310, thereby avoiding the situation in which the measuring tube 210 blocks the irradiation path of the light 340 after the measuring tube 210 is deformed, resulting in the light 340 failing to reach the laser receiving point 320.
[0067] The upper end of the measuring plate 230 is suspended on the inner surface of the measuring tube 210 , so that the measuring plate 230 can always remain in a vertical state, making it easier for the light 340 emitted by the laser emitter 220 to irradiate the measuring plate 230 , and also easier for the operator to record the laser point 330 .
[0068] In this embodiment, the measuring plate 230 is suspended on the inner surface of the measuring tube 210 through a movable light ring. In other embodiments, other suspension structures considered appropriate by those skilled in the art may also be selected.
[0069] The measuring plate 230 is provided with a scale ruler 231 , so that the position of the laser point 330 on the scale plate can be better located, making it more convenient for the operator to record the laser point 330 .
[0070] In this embodiment, the recording device 240 is a camera device, which can move along the extension direction of the measuring tube 210. The camera device is used to record the position of the light 340 emitted by the laser emitter 220 on the measuring plate 230, so that the camera device can record the measuring plate 230 at different positions in the extension direction of the measuring tube 210. According to the laser point position 330 on the measuring plate 230, the deformation conditions at different positions in the extension direction of the measuring tube 210 can be known, and the deformation monitoring of the measuring object 100 is more comprehensive. In other embodiments, other specific structures of the recording device 240 that are considered appropriate by those skilled in the art can also be selected.
[0071] In this embodiment, a slide rail 250 is provided inside the measuring tube 210, and the extension direction of the slide rail 250 is consistent with the extension direction of the measuring tube 210. The camera device can slide along the slide rail 250, so that the camera device can move in the extension direction of the measuring tube 210. The movement of the camera device is more convenient by providing the slide rail 250. In other embodiments, other sliding structures that are considered appropriate by those skilled in the art may also be selected.
[0072] The laser deformation monitoring device 200 further includes a traction member connected to the camera device. By providing the traction member connected to the camera device, the operator can move the camera device on the slide rail 250 by pulling the traction member, thereby making it easier for the operator to change the position of the camera device.
[0073] In this embodiment, the traction member is a traction rope. In other embodiments, other specific structures of the traction member that are considered suitable by those skilled in the art may also be selected.
[0074] This embodiment also provides a deformation monitoring method, which is implemented using a laser deformation monitoring device 200 and includes the following construction steps:
[0075] Step 1: Use a drill bit 400 to construct a hole 410 under the surface of the measurement object 100, so as to obtain a space for installing the measurement tube 210;
[0076] Step 2, inserting the measuring tube 210 into the borehole 410, so as to place the measuring tube 210 below the measuring object 100;
[0077] Step 3: injecting a fixing material 500 between the borehole 410 and the measuring tube 210 to fill the gap between the borehole 410 and the measuring tube 210 so that the measuring tube 210 can be more stably fixed in the borehole 410;
[0078] Step 4: At different time points, the laser transmitter 220 transmits light 340 from the laser emission point 310 to the laser receiving point 320;
[0079] Step 5, recording the position of the light 340 emitted by the laser emitter 220 on the measuring plate 230 at different time points by the recording device 240;
[0080] Step 6: Compare the positions of the light 340 emitted by the laser emitter 220 on the measuring plate 230 at different time points to obtain the deformation of the surface of the measuring object 100.
