Description

Technical Field

[0001] This invention relates to the field of urban rail transit exploration technology, specifically to an auxiliary device and method for geophysical straight survey line setting out in an indoor environment. Background Technology

[0002] With the continuous development of urban construction in my country, China's subway system has entered the world's leading ranks. Since subway projects are generally built in urban centers, shield tunnels often pass under or alongside existing structures, making these areas key areas for exploration. Because drilling cannot be densely deployed, geophysical exploration work needs to be conducted inside buildings to determine the distribution of unfavorable geological bodies beneath them. During the implementation of geophysical exploration in buildings, the accurate placement of straight survey lines is a core element in ensuring the validity of the exploration data. Especially when the survey lines are obstructed by structural walls, the straightness and spacing consistency of the survey lines may differ significantly from the pre-planned layout, directly affecting the accuracy of the geophysical exploration results.

[0003] Currently, the layout of geophysical straight survey lines inside buildings mainly relies on manual rope positioning, marking with a simple ruler, or using a total station for point-shifting. However, the interior environment of buildings is complex, with issues such as protruding walls, obstructions from doors and windows, and accumulated debris on the ground. The manual rope method is easily affected by environmental interference, making it difficult to guarantee the straightness of the survey line. Similarly, the total station point-shifting method is also inefficient or even impossible due to obstructions from walls and doors and windows. Existing layout methods lack effective fixing and calibration mechanisms, and the marked survey lines are easily blurred or shifted due to personnel collisions or environmental factors (such as damp walls), requiring subsequent detection work to be repositioned, increasing detection costs and time consumption.

[0004] Therefore, developing an auxiliary device that can adapt to the complex environment inside a building, achieve accurate positioning and stable indication of the direct measurement line, and facilitate the offset arrangement of the side measurement line has become a key issue that urgently needs to be solved in the field of building geophysical exploration. Summary of the Invention

[0005] The purpose of this invention is to provide an auxiliary geophysical survey line layout device and method for addressing the aforementioned technical problems, thereby solving the problems of poor straightness, weak adaptability to complex environments, low efficiency and large deviation in existing geophysical survey line layout methods, and improving the accuracy and efficiency of geophysical exploration in buildings.

[0006] The technical solution of the present invention: A geophysical survey line setting-out device for indoor environments includes a reference positioning module, a base support module, and an adsorption fixing module. The base support module is mounted on the adsorption fixing module, and the reference positioning module is mounted on the base support module.

The control panel is equipped with an adjustment column, a bubble level, and a start button. The compass is located at the top of the adjustment column. The vertical laser indicator, the horizontal laser indicator, and the battery are located on the side of the adjustment column. The control panel is located on the fine-tuning unit.

[0008] The fine-tuning unit includes at least three sets of level adjusters evenly arranged at the bottom of the worktable.

[0009] The leveling device includes an adjusting screw sleeve, a lifting column, and a fixing stud. The bottom of the adjusting screw sleeve is threadedly connected to the fixing stud, and the top of the adjusting screw sleeve is rotatably connected to the lifting column. The fixing stud is mounted on the base support module, and the operating platform is fixedly mounted on the top of the lifting column.

[0010] The bottom of the lifting column is provided with a frustum, and the top of the inner side of the adjusting screw sleeve is provided with a sliding groove that matches the frustum.

[0011] The base support module includes a fixing bolt, a bracket hinge, three telescopic legs, and an installation platform. The installation platform is connected to the telescopic legs via the bracket hinge. The fixing bolt is installed on the installation platform, and the top of the fixing bolt is matched and connected to the fixing stud.

[0013] The adsorption and fixation module includes an air pump, a vacuum suction cup, a charging port, a hose, a start button, and a cavity. The vacuum suction cup is connected to the air pump through the hose. The vacuum suction cup is connected to the bottom end of the cavity. The top end of the cavity is welded to the bottom end of the inner support rod. The charging port and the start button are provided on the outside of the cavity.

[0014] A method for setting out geophysical straight lines in an indoor environment includes the following steps: S1: Set the extension of the object detection line and record the length. Set the object detection line on the CAD drawing in advance and extend it. Record the extension length L to obtain the survey line layout diagram. S2: Drawing storage and transmission: Save the survey line layout drawing as a .dxf format file and transmit it to the RTK device; S3: Measure the orientation of the extension line. Use RTK equipment to lay out the pre-set extension section of the survey line outside the house. At the same time, use an orientation compass to measure and record the orientation α of the corresponding extension line.

[0015] S4: Clearly define the setting scenario and determine the usage method. Clearly define the setting scenario as an open space like a factory or a residential building with multiple walls covering the space, and determine the usage method.

[0016] Step S4, regarding the usage method for open space factory scenarios, includes the following steps: a1: Set up and adjust the benchmark positioning module, adjust the height of the layout device of this application according to the height of the light-transmitting doors and windows and level it, turn on the start button, so that the vertical laser line of the vertical laser indicator is along the extension line; a2: Deploy corresponding geophysical exploration equipment. If the vertical laser line of the vertical laser indicator can be guided to the factory building through doors and windows, then a measuring tape or measuring rope can be pulled along the vertical laser line inside the factory building according to the vertical laser line. The starting point of the preset straight measuring line can be found according to the measuring tape or measuring rope, and the corresponding geophysical exploration equipment can be deployed for detection. a3: If the vertical laser line cannot be guided to the factory building through doors and windows, place another stakeout device of this application on its left and right sides to ensure that the vertical laser line can be guided to the factory building through doors and windows. Based on the translation of the external laser line and the actual measurement line, set up another stakeout device of this application inside the factory building and adjust the horizontal laser line to be parallel to the horizontal laser line outside the building according to the azimuth compass α and the horizontal laser indicator. Project the vertical laser line to be consistent with the set geophysical straight measurement line, and proceed to the next step according to step a2. a4: Based on step a3, if the vertical laser line of the vertical laser pointer is blocked by a structural column or wall, select a reference point on the structural column or wall, measure the horizontal and vertical distance between the laser point on the column and the reference point, and use the reference point as the restored laser point on the back side of the structural column or wall. At this point, project a vertical laser line according to the orientation α, and proceed to the next step according to step a2. The usage method for residential-style scenarios with multiple walls obscuring the space includes the following steps: b1: Deploy and adjust the benchmark positioning module, and deploy the layout device of this application in the extended section of the survey line. If the vertical laser line of the vertical laser indicator can penetrate the door and window and enter the building, then operate according to step a2 in the usage method of open space factory scene. b2: If the vertical laser line of the vertical laser pointer cannot penetrate the door or window to enter the building, if another set of the layout device of this application can be set up by moving along the side to introduce the vertical laser line into the building, then the operation shall be carried out in step a3 of the usage method for open space factory scene. b3: If the vertical laser line of the vertical laser pointer cannot be introduced into the building through step a3 in the usage method for open space factory scenarios, drill a hole at the location where the vertical laser line of the vertical laser pointer is projected onto the building to allow the vertical laser line to enter the building. Then, you can operate according to step a3 in the usage method for open space factory scenarios.

[0017] The beneficial effects of this invention are: The reference positioning module of this application uses laser lines and a compass to quickly determine the orientation and path of the straight line. With the help of a bubble level, it can be calibrated in sloping or uneven building environments. The horizontal and vertical states of the layout device of this application provide a precise reference for the layout of the straight line, solving the problem of large errors in manual positioning.

[0018] The vacuum suction cup of the adsorption and fixing module of this application can adapt to complex surfaces such as uneven ground, curved surface, and slippery ground. With the telescopic support legs, it can stably fix the layout device of this application in scenarios such as inclined ground and narrow space, which solves the problem of difficulty in fixing existing devices in complex environments, and at the same time avoids the failure of the marked survey line due to the deviation of the layout device of this application.

[0038] A method for setting out geophysical straight lines in an indoor environment includes the following steps: S1: Set the extension of the object detection line and record the length.

At the same time, use the orientation compass 11 to measure the orientation α of the corresponding extension line and record it.

[0039] In practical applications, since GPS cannot be located inside buildings, the layout device of this application cannot be placed on the preset survey line.

[0040] S4: Clearly define the setting scenario and determine the usage method. Clearly define the setting scenario as an open space like a factory or a residential building with multiple walls covering the space, and determine the usage method.

[0041] Step S4, regarding the usage method for open space factory scenarios, includes the following steps: a1: Set up and adjust the reference positioning module, adjust the height of the layout device of this application according to the height of the light-transmitting doors and windows and level it, turn on the start button 111, so that the vertical laser line of the vertical laser indicator 12 is along the extension line; Specifically, for open space factory scenarios, which are characterized by their spacious interiors and the presence of a few obstructing walls, the layout of the direct measurement line is relatively simple. The present application's layout device is installed on the extended section of the measurement line. After adjusting the height of the layout device appropriately according to the height of the light-transmitting doors and windows and leveling it, the start button 111 is turned on, so that the vertical laser line of the vertical laser indicator 12 follows the extended line. a2: Deploy corresponding geophysical exploration equipment. If the vertical laser line of the vertical laser indicator 12 can be guided to the factory building through the door or window, then a measuring tape or measuring rope can be pulled along the vertical laser line inside the factory building according to the vertical laser line guidance. The starting point of the preset straight measuring line can be found according to the measuring tape or measuring rope, and corresponding geophysical exploration equipment can be deployed for detection. a3: If the vertical laser line cannot be guided to the factory building through doors and windows, place another stakeout device of this application on its left and right sides to ensure that the vertical laser line can be guided to the factory building through doors and windows. Based on the translation of the external laser line and the actual measurement line, set up another stakeout device of this application inside the factory building and adjust the horizontal laser line to be parallel to the horizontal laser line outside the building according to the azimuth indicator compass 11 azimuth α and the horizontal laser indicator 13. Project the vertical laser line to be consistent with the set geophysical straight measurement line, and proceed to the next step according to step a2. a4: Based on step a3, if the vertical laser line of the vertical laser pointer 12 is blocked by a structural column or wall, a reference point is selected on the structural column or wall, the horizontal and vertical distances between the laser point on the column and the reference point are measured, and the reference point is used as the restored laser point on the back side of the structural column or wall. At this point, a vertical laser line is projected according to the orientation α, and the next operation is carried out according to step a2. The usage method for residential-style scenarios with multiple walls obscuring the space includes the following steps: b1: Deploy and adjust the benchmark positioning module, and deploy the layout device of this application in the extended section of the survey line. If the vertical laser line of the vertical laser indicator 12 can penetrate the door and window and enter the building, then operate according to step a2 in the usage method of open space factory scene. Specifically, in actual use, the characteristics of residential-style scenarios with multiple walls obscuring the space are that the internal walls and structural columns are complicated, and there may be multiple light source obstructions on the pre-set object detection line. Therefore, the layout device of this application is set up in the extended section of the measurement line. b2: If the vertical laser line of the vertical laser pointer 12 cannot penetrate the door and window to enter the house, if another set of the layout device of this application can be set up by moving the side line to introduce the vertical laser line into the house, then the operation shall be carried out in step a3 of the usage method of open space factory scene. b3: If the vertical laser line of the vertical laser pointer 12 cannot be introduced into the building through step a3 in the method of using an open space factory scene, drill a hole at the location where the vertical laser line of the vertical laser pointer 12 is projected onto the building, so that the vertical laser line enters the building, and then you can operate according to step a3 in the method of using an open space factory scene.

The usage method for residential-style scenarios with multiple walls obscuring the space includes the following steps: b1: Set up the adjustment benchmark positioning module and set up the layout device of this application in the extended section of the survey line. If the vertical laser line of the vertical laser indicator (12) can penetrate the door and window and enter the house, then operate according to step a2 in the usage method of open space factory scene. b2: If the vertical laser line of the vertical laser pointer (12) cannot penetrate the door and window to enter the house, if another set of the layout device of this application can be set up by moving the side line to introduce the vertical laser line into the house, then the operation shall be carried out in step a3 of the method of use in open space factory scene. b3: If the vertical laser line of the vertical laser pointer (12) cannot be introduced into the house through step a3 in the method of using an open space factory scene, drill a hole at the location where the vertical laser line of the vertical laser pointer (12) is projected onto the house so that the vertical laser line enters the house. Then, you can operate according to step a3 in the method of using an open space factory scene.
