Description

Technical Field

[0001] The utility model relates to the technical field of surveying, in particular to a marking auxiliary device for rock and soil surveying. Background Art

[0002] The purpose of geotechnical engineering investigation is to use testing means and methods to investigate, study and analyze the construction site, study the geological conditions for building various engineering buildings, and the impact of construction on the natural geological environment. When conducting the investigation, the survey area needs to be marked, generally by marking flags. When the marking flags are inserted into the ground for marking, the connection strength between the marking flags and the ground is poor. In windy weather, the marking flags inserted in the ground are easily blown up, causing the marking flags to separate from the ground. Therefore, auxiliary devices are needed to fix the marking flags, but the auxiliary devices have poor fixing effects on the marking flags. Utility Model Content

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A marking auxiliary device for geotechnical survey is designed, including a fixed frame, a plurality of plug rods are fixedly connected to the bottom end of the fixed frame, a mounting frame is fixedly connected to the fixed frame, a groove is formed at the upper end of the mounting frame, a threaded hole is formed on the mounting frame, the threaded hole is connected to the groove, a threaded rod is connected to the threaded hole, one end of the threaded rod is rotatably connected to a pressure plate, and the pressure plate is located in the groove.

[0006] Preferably, the pressure plate is an arc-shaped plate.

[0007] Preferably, a plurality of raised blocks are fixedly connected to the bottom end of the fixing frame.

[0008] Preferably, a prompt mechanism is fixedly connected to the upper end of the fixed frame, and the prompt mechanism comprises a fixing frame, the fixing frame is fixedly connected to the upper end of the fixed frame, and an indicator sign is fixedly connected to the outer side of the fixing frame.

[0009] Preferably, a fluorescent sign is fixedly connected to the outer side of the fixing frame.

[0010] The utility model provides a marking auxiliary device for geotechnical exploration, which has the following beneficial effects:

[0011] When fixing the marking flag, the fixing frame is plugged into the ground through a plurality of plug rods, the fixing frame is stably fixed on the ground, the bottom end of the marking flag is inserted into the groove, and the threaded rod is rotated. After the threaded rod is rotated, the pressure plate is driven to move toward the marking flag. After moving a certain distance, the pressure plate contacts and squeezes the bottom of the marking flag, and the marking flag is fixed on the groove. The marking flag has a good fixing effect. In windy weather, the marking flag will not fall over, thereby improving the fixing effect of the marking flag. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] 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.

[0018] Example 1: Reference Figure 1-4 A marking auxiliary device for geotechnical exploration includes a fixed frame 1, a plurality of plug rods 2 are fixedly connected to the bottom end of the fixed frame 1, a mounting frame 3 is fixedly connected to the fixed frame 1, a groove 4 is opened at the upper end of the mounting frame 3, a threaded hole is opened on the mounting frame 3, the threaded hole is connected to the groove 4, a threaded rod 5 is connected to the threaded hole, one end of the threaded rod 5 is rotatably connected to a pressure plate 6, the pressure plate 6 is an arc-shaped plate, the pressure plate 6 is located in the groove 4, and a plurality of protrusions 7 are fixedly connected to the bottom end of the fixed frame 1.

[0019] Working process:

[0020] When fixing the marking flag, the fixing frame 1 is plugged into the ground through a plurality of insertion rods 2. The plurality of insertion rods 2 are distributed in a quadrilateral shape to stably fix the fixing frame 1 on the ground. The protruding block 7 is located between the fixing frame 1 and the ground, so that there is a gap between the fixing frame 1 and the ground, which facilitates the drainage of water inside the fixing frame 1 from the gap on rainy days. The bottom end of the marking flag is inserted into the groove 4, and the threaded rod 5 is rotated. After the threaded rod 5 rotates, it drives the pressure plate 6 to move toward the marking flag. After moving a certain distance, the pressure plate 6 contacts the bottom of the marking flag and squeezes it, fixing the marking flag on the groove 4. The marking flag has a good fixing effect. In windy weather, the marking flag will not fall over, thereby improving the fixing effect of the marking flag.

[0021] Example 2: In Example 1, after the fixing frame 1 is plugged into the ground through a plurality of plug rods 2, due to the lack of markings, personnel are prone to damage the device and it is difficult to find it at night. Figure 1 As another preferred embodiment of the utility model, the difference from embodiment 1 is that a prompt mechanism 8 is fixedly connected to the upper end of the fixed frame 1, and the prompt mechanism 8 includes a fixed frame 81, and the fixed frame 81 is fixedly connected to the upper end of the fixed frame 1. An indicator board 82 is fixedly connected to the outer side of the fixed frame 81, and a fluorescent board 83 is fixedly connected to the outer side of the fixed frame 81. The fixed frame 81 fixes the indicator board 82, and the indicator board 82 displays the device to play a prompt effect to prevent people from damaging the device. At the same time, the fluorescent board 83 emits fluorescence at night to facilitate finding the device.

[0022] 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.
