Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit support measurement, in particular to a foundation pit support inclination measurement device. Background Art

[0002] Foundation pit support is a series of technical measures taken in construction projects to ensure the stability of the surrounding soil and the safety of adjacent structures during foundation pit excavation. These measures involve the use of various methods and materials, such as steel supports, concrete spraying, anchors, soil nail walls, and prefabricated or cast-in-place concrete walls, to form effective support for the soil. The purpose of foundation pit support is to prevent foundation pit collapse, control groundwater levels, reduce the impact of foundation pit excavation on the surrounding environment, ensure the safety of construction workers, and protect the integrity of surrounding buildings and facilities. When designing foundation pit support, it is necessary to comprehensively consider factors such as geological conditions, foundation pit depth, surrounding environment, and construction methods to ensure that the support measures taken are both economical and effective.

[0003] For foundation pit support, the slope of foundation pit support is usually 1:1 to 1:1.5, which means that when the horizontal distance is 1 meter, the vertical distance is usually 1 to 1.5 meters. Such a slope can effectively reduce the slope of the soil slope and reduce the risk of soil collapse. However, there is no systematic measurement method for the inclination of foundation pit support, that is, the slope detection in the prior art.

[0004] Therefore, a foundation pit support inclination measuring device is proposed to solve or alleviate the above problems. Utility Model Content

[0007] A foundation pit support inclination measuring device comprises a telescopic rod, a vertical laser sensor 1, a vertical laser sensor 2, a transverse laser sensor, and a touch screen, wherein the vertical laser sensor 1 and the vertical laser sensor 2 are respectively fixedly connected to the bottoms of both ends of the telescopic rod, the transverse laser sensor is fixedly connected to the end of the telescopic rod and is located above the vertical laser sensor 1, and the processor in the touch screen is coupled with the vertical laser sensor 1, the vertical laser sensor 2, and the transverse laser sensor to display feedback data.

[0008] Preferably, a baffle facing the transverse laser sensor is provided at one end of the telescopic rod away from the transverse laser sensor.

[0009] Preferably, a fixing ring is sleeved on one end of the telescopic rod away from the transverse laser sensor, and the baffle is fixedly connected to the fixing ring.

[0012] Preferably, a level is embedded on the handle and located between the first fixing ring and the second fixing ring.

[0013] The utility model has the following beneficial effects:

[0014] During the operation of the utility model, personnel need to stand on the foundation pit support and manually adjust the telescopic rod to match the distance between the upper and lower ends of the foundation pit. After adjustment, the actual length of the telescopic rod is measured using a horizontal laser sensor, and the vertical laser sensor 1 and the vertical laser sensor 2 are used to determine the slope.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] A foundation pit support inclination measuring device, such as Figure 1 As shown, it includes a telescopic rod 2, a vertical laser sensor 1 4, a vertical laser sensor 2 5, a horizontal laser sensor 6, and a touch screen 11.

[0021] First, Figure 2As shown, the small end of the telescopic rod 2 is fixedly connected to a connector 3 mounted on its outside, and mounting planes are provided on the top and bottom surfaces of the connector 3. A vertical laser sensor 4 is fixedly connected to the mounting plane on the bottom surface of the connector 3, so that it is located at one end of the telescopic rod 2, and a transverse laser sensor 6 is fixedly connected to the mounting plane on the top surface of the connector 3, so that it is located above the vertical laser sensor 4.

[0022] like Figure 3 As shown, the vertical laser sensor 2 5 is fixedly connected to one end of the large end of the telescopic rod 2, and is arranged on the same side as the vertical laser sensor 1 4. A fixing ring 7 is sleeved on the end of the telescopic rod 2 away from the transverse laser sensor 6, and a baffle 8 facing it is arranged on the end of the telescopic rod 2 away from the transverse laser sensor 6. The baffle 8 is fixedly connected to the fixing ring 7, and is used to reflect the laser emitted by the transverse laser sensor 6.

[0023] like Figure 3 As shown, one end of the telescopic rod 2 away from the transverse laser sensor 6 is coaxially fixedly connected with a handle 1, and a spirit level 12 located between a fixing ring 1 7 and a fixing ring 2 9 is embedded on the handle 1. A fixing ring 2 9 is sleeved on the handle 1, and the fixing ring 2 9 is fixedly connected to the back of a touch screen 11 through a connecting frame 10. The processor in the touch screen 11 is coupled with the vertical laser sensor 1 4, the vertical laser sensor 2 5, and the transverse laser sensor 6 to display feedback data. The touch screen 11 can adopt the AMZ070W1RAG model of the Jinxi brand, and the coupling of the vertical laser sensor 1 4, the vertical laser sensor 2 5, and the transverse laser sensor 6 to it does not involve any modification, and it is a basic wiring method understood by those skilled in the art, so it will not be repeated here.

[0024] The above-mentioned fixing ring 1 7 and fixing ring 2 9 both include two Ω-shaped ring pieces. After the two ring pieces are fitted together, they are connected by bolts and nuts, so as to be clamped on the telescopic rod 2 and the handle 1.

[0025] When the utility model is in use, the operator only needs to stand on the top of the foundation pit support (since most foundation pit supports are soil nail walls, there will be no problem of the operator being unable to stand on the top), and manually extend the telescopic rod 2 according to the distance between the upper end and the lower end of the foundation pit support. After the telescopic rod 2 is extended, the distance between the vertical laser sensor 1 4 and the horizontal laser sensor 6 changes compared to the vertical laser sensor 2 5. At this time, the distance between the horizontal laser sensor 6 and the baffle 8 changes, so that the current length of the telescopic rod 2 can be measured, and the distance between the upper end and the lower end of the foundation pit support can be obtained, while the vertical laser sensor 1 4 and the vertical laser sensor 2 5 can measure the distance between the two on the slope of the foundation pit support. Calculations are performed and the data are fed back to the touch screen 11. At the same time, in order to ensure the accuracy of the data, the vertical laser sensor 4 and the vertical laser sensor 25 are required to remain horizontal and vertically located above the foundation pit support. The level 12 can better serve as a reference for the adjustment of the entire device. Finally, the operator can calculate the inclination through the distance between the upper and lower ends of the foundation pit support, the vertical laser sensor 4 and the vertical laser sensor 25 to the data on the slope of the foundation pit support. Of course, the calculation method can also be directly set in the processor of the touch screen 11. Specifically, the length of the inclined plane is calculated through the Pythagorean theorem, and then the inclination is calculated through trigonometric functions. The above content does not involve improvements to the computer program.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
