Detailed Description
The application is described in further detail below with reference to fig. 1-2.
The embodiment of the application discloses a visual control method in an anchoring process of an anchoring piece. The method is applied to the visual management system of the anchoring process, and the program codes corresponding to the method are prestored in a control center of the visual management system of the anchoring process. In the application, the anchoring part mainly refers to an anchor of an anchor cable type, and the anchoring construction process flow mainly comprises the following six steps, namely, the frame is in place, and in certain engineering projects, the anchoring point of the anchor cable is positioned at a higher position and is not accessible by manpower, so that a constructor needs to be positioned at the higher position by virtue of the frame; secondly, an anchor hole is drilled, wherein the main requirements of the anchor hole are to ensure the hole depth, the aperture and the inclination angle of the hole, the hole depth is required to be more than 50cm so as to avoid the influence of sediment on the effective hole depth, and after the anchor hole depth meets the standard, the hole wall is cleaned by adopting slurry, and the sediment is carried out. If the underground obstacle is encountered in the process of drilling the anchor hole, the down-the-hole drill is adopted to remove the obstacle, and if the underground obstacle is encountered on a pile foundation of a nearby building, the horizontal distance and the angle of the anchor hole can be properly adjusted; thirdly, manufacturing and installing the anchor cable, wherein the manufacturing and installing of the anchor cable body mainly refers to manufacturing and installing of the anchor cable body according to the requirements of engineering projects; fourthly, grouting, wherein the construction worker can adopt twice grouting according to the geological conditions of the field engineering, and grouting can stop continuously drilling the anchor hole after the anchor hole is drilled to the depth exceeding 50cm for the first time, the grouting occurs when the anchor hole is prepared to be cleaned, and grouting is started when the slurry flowing out of the orifice becomes thin and no slurry abrasive belt exists. Adopting hole bottom grouting, stopping the first grouting when thick cement slurry flows out of the hole opening, performing high-pressure splitting grouting when the second grouting is performed, and immediately performing splitting grouting on the anchoring section by adopting cement slurry after the first grouting is performed for 3-5 hours.
The fourth step is to stretch the cable, and in general, the stretching process adopts a plurality of multi-stage stretching processes, each bundle of steel strands is straightened by pre-stretching, and each stage of stretching is stabilized for a period of time so as to facilitate the transmission and adjustment of the pre-stress in the cable. The time interval between the two stretching is longer, and the second stretching is performed after the prestress of the first stretching is basically stable so as to compensate the prestress loss. The total tonnage of the tensioning is not less than the design tonnage (including overstretching), the anchor cable drawing test can be carried out first for checking the design of the anchoring section, and the design is modified if the design requirement is not met. It is worth mentioning that the pre-tensioning can be performed after grouting by maintaining for more than 25-30 days; and the fifth step is to lock the anchor cable, after overstretching, the constructor locks the anchor cable on the anchorage device, emphasizes the locking process, reduces the inward shrinkage of the clamping piece so as to prevent prestress loss, cuts off the surplus length of the steel strand after the anchor cable is locked, and reserves a certain length of the steel strand for re-tensioning when the prestress attenuation after the anchor cable is predicted to be too large.
As shown in fig. 1, the method comprises the steps of:
s10, acquiring field image information in the anchoring process of the anchor.
Specifically, construction workers can put image acquisition devices on construction sites, in order to ensure that various information is not missed in the anchoring process, the number of the image acquisition devices can be not unique and put to various proper angles, so that lenses of the image acquisition devices can not be shielded. And the image acquisition device and the anchoring process visual management system have a data transmission function, so that the image acquisition device can send the latest on-site image data to the anchoring process visual management system in real time.
In this embodiment, the image capturing device may be a camera, and thus, the captured live image data may be a photograph of the recorded anchoring process. In an embodiment, the image acquisition device may also be a camera, whereby the acquired live image data may be video of the recorded anchoring process. When the image acquisition device is a camera, the anchoring process visualization management system can call the camera to take a picture of the anchoring site at intervals of a preset time, for example, every 1 minute or 2 minutes, so as to take a picture of the anchoring site and obtain image data of the anchoring site; when the image acquisition equipment is a camera, the anchoring process visual management system can always acquire images of the anchoring site after the anchoring process of the anchoring part begins, so that videos of the anchoring site are obtained.
In the application, the image acquisition equipment acquires site image information, wherein the site image information comprises an anchoring drilling image, an actual anchoring image and an anchoring position surface image, the anchoring drilling image refers to image information shot for fixing an anchoring hole formed by an anchoring piece, the actual anchoring image refers to scene information shot when a constructor inserts the anchoring piece into the anchoring space at a certain inclination angle, and the anchoring position surface image refers to image data after grouting the plane of an anchoring point by the constructor.
S20, detecting the field image information.
Specifically, the anchoring process visual management system performs element recognition and detection on the field image information after receiving the phenomenon image information sent by the image acquisition device, for example, when the acquired field image information is an anchoring borehole image, the anchoring borehole image further includes background pixels besides the anchoring borehole, which are pixel data not required by the anchoring process visual management system, so that when the anchoring process visual management system recognizes a target element in the field image information, the subsequent detection operation is performed based on the recognized target element.
S30, judging whether the anchoring process is abnormal according to the detection result of the field image information.
Specifically, after identifying a target pixel in the field image information, the visual management system of the anchoring process monitors the structure and operation in the anchoring process of the target pixel anchor, judges whether the structure and operation meet the anchoring standard, and if the structure and operation are detected to meet the anchoring requirement, judges that the anchoring process of the anchor is not abnormal; if the detected structure and operation have the phenomenon that the anchoring requirement is not met, the anchoring process visual management system can judge that the anchoring process of the anchoring piece is abnormal.
S40, if the anchoring process is abnormal, generating an alarm signal.
Specifically, when the visual management system cabinet of the anchoring process judges that an abnormality occurs in the anchoring process of the anchoring element, the mechanical structure in the anchoring process is described, and the operation of constructors is in a situation that does not meet the anchoring standard and may cause failure of anchoring of the anchoring element, so that the visual management system of the anchoring process can remind the constructors in a mode of generating an alarm signal, the alarm signal can be expressed in a mode of emitting an alarm sound or an alarm lamp tube, and of course, the expression mode is of various other types, and the two common modes are listed. The monitoring function of the visual management system in the anchoring process enables constructors to find out once the posture of the anchoring element deviates from a preset track in the anchoring process, and accuracy and rapidness in the anchoring process of the anchoring element are improved.
In one embodiment, to reduce the likelihood of anchor failure, the field image information is detected, specifically, the following steps may be performed:
if the obtained on-site image information is an anchoring borehole image, the visual management system in the anchoring process firstly identifies the anchoring borehole pixels in the image, namely the target pixels in the image, extracts the pixel information related to the anchoring borehole, and calculates the aperture length of the anchoring borehole.
In one embodiment, to ensure that the anchor pose is correct during the anchoring process, the detection of the field image information may be further performed as steps of:
the method comprises the steps of obtaining an anchor drilling image and an actual anchor image, constructing a simulated anchor image on the anchor drilling image according to a preset inclination angle, specifically, storing an anchor image used in actual construction operation in advance in an anchor process visual management system, combining the anchor image and the anchor drilling image by the anchor process visual management system to obtain a simulated anchor image, wherein one end of an anchor is connected with the anchor drilling in the simulated anchor image, an included angle between the anchor and a plane of the anchor drilling is consistent with the preset inclination angle, and the fact that a shooting angle corresponding to the generated simulated anchor image is consistent with a shooting angle corresponding to the actual anchor image is needed to facilitate subsequent comparison operation. In order to facilitate the description hereinafter, the anchors in the simulated anchor image are distinguished from the anchors in the actual anchor image, and therefore, the anchors in the simulated anchor image are referred to herein as virtual anchor pixels, and the anchors in the actual anchor image are referred to as actual anchor pixels. And then, the visual management system in the anchoring process compares the actual anchoring image with the anchoring drilling image, judges whether the virtual anchoring pixels in the two images are consistent with the actual anchoring pixels, if not, generates an anchoring posture adjustment instruction to remind constructors that the inclination angle of the anchoring part deviates from a preset inclination angle, and further helps to ensure that the posture of the anchoring part in the anchoring process is correct.
In one embodiment, to improve accuracy of the anchor pose detection result, determining whether the virtual anchor pixel is consistent with the actual anchor pixel may be specifically performed as the following steps:
the anchoring process visualization management system sets one end of a virtual anchoring pixel close to an anchoring drilling hole as a first end point, segments the virtual anchoring pixel according to a preset sampling distance by taking the first end point as a starting point to obtain a plurality of first sampling points, wherein the sampling points are segmentation points in the simulation anchoring pixel, the serial number value of the first sampling points is set according to the distance between the first sampling points and the first end point, and the serial number value of the first sampling points which are closer to the first end point is smaller; then, the same processing mode is adopted for the actual anchor pixels, and one end of the actual anchor pixels, which is close to the anchor drilling hole, is set as a second endpoint; and dividing the actual anchor pixels by taking the second endpoint as a starting point according to a preset sampling distance to obtain a plurality of second sampling points, setting the sequence number value of the second sampling points according to the distance between the second sampling points and the second endpoint, and sequentially acquiring the first sampling points and the second sampling points with the same sequence number value as the sequence number value of the second sampling points which are closer to the second endpoint is smaller, for example, the anchoring process visualization management system acquires the first sampling points and the second sampling points with the sequence number value of 2 at the same time.
The method comprises the steps of determining coordinate data of acquired first sampling points and second sampling points in image information, calculating point distance values between the first sampling points and the second sampling points by utilizing a point distance formula, wherein the number of the first sampling points and the second sampling points is not unique, so that the point distance values obtained by an anchoring process visual management system are not unique, searching for the maximum value among a plurality of point distance values, recording the maximum value as the maximum point distance value, comparing the maximum point distance value with a preset reasonable deviation threshold value, judging that the included angle between a virtual anchor pixel and an actual anchor pixel is not consistent when the maximum point distance value is larger than the reasonable deviation threshold value, and determining that the included angle between the virtual anchor pixel and the actual anchor pixel is overlarge.
In one embodiment, to improve the applicability of the anchoring process visualization management system, the detection of the field image information may be further performed as the following steps:
if the obtained field image information is an anchoring position surface image, in general, in order to improve stability of the anchoring point, a constructor will perform grouting treatment on a plane where the anchoring point is located and perform grouting operation to uniformly spray, so that the plane where the anchoring point is located after grouting should be a relatively flat plane. The visual management system in the anchoring process identifies the highest pixel point and the lowest pixel point in the surface image of the anchoring position, calculates the height difference between the highest pixel point and the lowest pixel point, compares the height difference with a preset standard height threshold value, if the calculated height difference exceeds the standard height threshold value, the flatness of the plane where the current anchoring point is located is poor, the visual management system in the anchoring process can generate prompt information to inform constructors of the phenomenon, and the constructors judge whether re-guniting is needed or not, so that the applicability of the visual management system in the anchoring process is improved.
