Description

Technical Field

[0001] The invention relates to a surveying device for making engineering survey control points, in particular to a portable device and method for ultra-long distance engineering survey control points. Background Art

[0002] In urban construction, control networks need to be laid out at the beginning of building construction, tunnels, bridges, and pipeline projects. When measuring control network points, it is usually necessary to set up measurement control points on the roof of a building or on a bridge. There are many high-rise buildings in the city. Placing control points on the top of a building has a wide field of view and is not easily blocked or damaged. The receiver signal is stable during GNSS measurement, and the points can be preserved for a long time. The entire line of the subway design route and the viaduct can be measured. Total station backsight orientation is a method to ensure measurement accuracy. It requires that the distance between the station and the backsight point be greater than the distance between the station and the layout point. The accuracy of the oriented side will directly affect the accuracy of the side to be measured, ensuring that the long side controls the short side, that is, the backsight point should be farther than the measurement target point to reduce error accumulation.

[0003] Making control points is the basis for measuring control networks in engineering construction. In general, in order to lay out and maintain these control points, it may be necessary to carry out construction activities such as burying expansion screws on the roof of the building, which may involve damaging the waterproof layer; in rear-sight orientation, the longer the distance, the lower the resolution of the telescope, the lower the clarity, and it is difficult for the aiming part to capture the target point. How to solve this problem in the measurement process, and how to control the long distance of the rear-sight point in engineering construction.

[0004] This is an issue that needs to be handled with caution. The waterproof layer is an important part of the building. It prevents moisture from penetrating into the structure of the building and causing corrosion, mildew, leakage or other potential structural problems. Therefore, if the waterproof layer needs to be destroyed to set or maintain the roof control point, appropriate measures must be taken to protect the structural integrity of the building; the shorter the distance of the backsight orientation edge, the worse the orientation accuracy will be. The measurement error of the short side leading the long side will double. How to complete high-precision orientation when encountering a long-distance backsight orientation edge? In order to meet the design requirements of engineering measurement control points, it is also imperative to study and do a good job of measuring points that can meet the needs of the project.

[0005] At present, there are two methods for laying out measurement control points in urban construction. One is to bury iron nails on the ground or make forced centering points. The points laid out on the ground are not conducive to long-term protection, and the visibility is poor. They are easily blocked by vehicles and pedestrians. Long-term rolling by vehicles will cause point changes and settlement displacement. The second is to lay out points on the roof of high-rise buildings. In the past, the points laid out required the tripod to be buried on the top floor of the building with expansion screws. The use of expansion screws will destroy the roof waterproof layer, which is not conducive to the later waterproofing of the building.

[0006] Therefore, the layout of engineering control points is the key to urban construction and a long-term activity. Long-distance rear-view marker targets play an important role in engineering measurement and can be used to determine and control key points in the control network, thereby ensuring the accuracy and quality of the entire project. How to provide a non-destructive device to solve this technology has become an urgent technical problem in this field. Summary of the invention

[0007] The purpose of the present invention is to solve the problem of not damaging the roof structure and waterproof layer and long-distance rear-sight orientation when the above-mentioned engineering survey control points are arranged on the roof, and to provide a portable device and method for ultra-long-distance engineering survey control points.

[0008] In order to solve the above technical problems, the present invention adopts the following technical solutions: a portable device used for ultra-long distance engineering measurement control points, comprising: a welding frame, a top support rod, a forced centering disk, a prism, a light strip power cord, a customized target board, and an LED light strip. The top support rod is welded at the top position of the welding frame, and the center of the top support rod is fixedly installed with a forced centering disk, which serves as a forced centering point for setting up a total station and a prism; the LED light strip is pasted at the center position of the customized target board, and is connected to a power bank by connecting the light strip power cord to light up the LED light strip, and the total station is aimed at the LED light strip to complete the orientation.

[0009] Furthermore, the welded frame is made of angle iron, and its size is determined by parameter size data obtained through field survey.

[0010] Furthermore, a reserved hole for installing a forced centering disk is provided at the center of the top support rod, which is used to install and fix the forced centering disk.

[0011] Furthermore, an intermediate support rod is installed in the middle of the welding frame to bear pressure and tension of the welding frame, making the welding frame structure more stable when subjected to stress.

[0012] Furthermore, fixing nuts are welded at the four corner points at the bottom of the welding frame, screw rods are screwed into the nuts, and gaskets are welded on the top of the screw rods; the screw rods are perpendicular to the outside of the wall and are used to fix the welding frame.

[0013] Further, the centering plate is fixed at the top support rod position by nuts and washers.

[0014] Furthermore, the customized target plate is used when the original target cannot meet the measurement work requirements. It is replaced with a customized target plate so that it can be easily found and effectively identified during long-distance observation and orientation.

[0016] Step 1: Survey and select the site, obtain the parameter size data of the welding frame, the width and height of the parapet wall at the top of the building, and the size of the welding frame required, determine the site location, and start making the frame;

[0017] Step 2: After the welding of the welding frame is completed, select and make the top support rod, which is used to support the forced centering plate and the measuring instrument. The center position of the top support rod is reserved with a hole for installing the forced centering plate, and the top support rod is welded to the middle position of the top of the manufactured frame;

[0018] Step 3: Weld four nuts to the four corner points at the bottom of the frame, screw the screw rods into the four nut positions, and then weld the washers to the screw ends of the four screw rods. The direction of the nuts is facing the wall. The screw rods pass through the nuts. The washers are welded to the top of the screw rods to increase the force-bearing area between the screw rods and the wall and protect the wall surface. The screw rods are perpendicular to the outside of the wall. Tighten the screw rods with a wrench so that the top of the screw rods is against the wall to tighten the force to fix the welded frame.

[0019] Step 4: After the welding frame is fixed, install the forced centering plate and fix it to the top support rod position with nuts and washers as the forced centering point for setting up the total station and prism;

[0020] Step 5: When the original target cannot meet the measurement requirements, replace it with a customized target according to the bottom of the original target and the matching size of the prism, so that it is easier to find the target during long-distance rear-view orientation. The LED light strip is pasted on the center of the customized target, and the customized target is lit through the power cord of the light strip.

[0032] Welding frame 1 is made of angle iron. When surveying and selecting the site, field survey is conducted to obtain parameter size data, such as the parapet wall width and height at the top of the building, as well as the size of the welding frame required. After the on-site location is determined, the frame is made. The production and use of roof control points must comply with relevant laws, regulations and safety regulations.

[0034] The middle support rod 3 is installed in the middle position of the welding frame 1. The middle support rod 3 is used for the pressure-bearing and tension-resisting effects of the welding frame, and makes the welding frame structure more stable when subjected to force.

[0035] The nuts 8 are welded and fixed at the four corner points at the bottom of the frame. After the screw rods 9 are screwed into the four nut 8 positions with a wrench 10, the washers 9 are welded and fixed at the screw ends of the four screw rods 7. The direction of the nuts 8 faces the wall position, the screw rods 7 pass through the nuts 8, and the washers 9 are welded to the top of the screw rods 7 to increase the force-bearing area between the screw rods 7 and the wall and protect the wall surface. The screw rods 7 are perpendicular to the outside of the wall and are used to fix the welded frame 1.

[0036] Forced centering plate 4 is fixed to the top support rod 2 with nuts 8, washers 9 and wrenches 10, serving as the forced centering point for setting up the total station and prism 11.

[0037] The size of the customized target plate 14 should be large enough.

All structures are prefabricated structures, which can be installed quickly and without damage. When used, the structure is subjected to forces in four directions, and the structure is stable, ensuring the accuracy and quality of the project. The device is used at the point, which can be installed quickly and without damage, greatly saving time and cost.

[0040] like Figure 6 As shown, a method for manufacturing a portable device for ultra-long distance engineering measurement control points of the present invention specifically comprises the following steps:

[0041] Step 1: Obtain the parameter size data required to make the welding frame 1, measure the parapet wall width and height at the top of the building, and the size of the welding frame 1 required, determine the on-site location, and start making the frame.

[0042] Step 2: After the welding frame 1 is welded, select and manufacture the top support rod 2, pre-install the hole position of the forced centering plate 4 at the center position of the top support rod 2, and weld the top support rod 2 to the middle position of the top of the manufactured frame.

The screw rod 7 passes through the nut 8 and the gasket 9 is welded to the top of the screw rod 7. The screw rod 7 is perpendicular to the outside of the wall. Use a wrench 10 to tighten the screw rod 7 so that its top is against the wall and tightened to bear the force. At this time, the welded frame 1 is fixed.

[0047] Step 5: Figure 5 If the original target 13 shown cannot meet the measurement requirements, the bottom of the original target 13 of the rear-view prism is replaced with a customized target plate 14 according to the matching size of the prism, so that the target can be found more easily during long-distance rear-view orientation. The LED light strip 12 is pasted on the center of the customized target plate 14, and the customized target plate 14 is lit by the light strip power cord 12. The total station only needs to aim at the LED light strip 15 to complete the orientation.

[0048] Step 6: After all steps are completed, the points are connected to the ground wire for lightning protection, and the layout and installation of the points are completed.
