Description

A ground marking device for engineering surveying Technical Field

[0001] This utility model relates to the field of engineering surveying technology, specifically to a ground marking device for engineering surveying. Background Technology

[0002] In the field of engineering surveying, ground markers, as the core carrier of spatial benchmarks, require high-precision installation to ensure the long-term stability of their coordinates and elevation. Traditional ground markers (such as concrete markers and metal boundary stakes) typically employ rigid fixed installation. Although this method can meet the initial positioning accuracy requirements, its inability to fine-tune is a significant technical shortcoming throughout the entire engineering cycle. Construction areas may experience foundation deformation due to fill compaction, groundwater level fluctuations, or frost heave, leading to deviations between the marker points and the design positions. Alternatively, the fixed positions of the initial markers may not be suitable for the local adjustments required in subsequent processes. The inability to fine-tune ground markers results in insufficient adaptability in dynamic engineering environments, leading to problems such as high repair costs, accuracy loss, and low collaborative efficiency. Therefore, this application proposes a ground marker device for engineering surveying to address the aforementioned issues. Summary of the Invention

[0022] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] As shown in Figures 1-6, this utility model provides a technical solution: a ground marking device for engineering surveying, including a fixed cylinder 1, a marker 2 disposed inside the fixed cylinder 1, an adjustment space formed between the marker 2 and the inner wall of the fixed cylinder 1, and a sealing cover 3 disposed at the top of the fixed cylinder 1. The top side of the sealing cover 3 has a groove, which can be used to rotate the sealing cover 3 by inserting a tool into the groove. The sealing cover 3 is connected to the top of the fixed cylinder 1 by a thread, and the outer wall of the sealing cover 3 is threadedly fitted to the inner wall of the fixed cylinder 1. After the sealing cover 3 is installed, it can seal the top of the fixed cylinder 1 and the marker 2. To provide protection, the fixing cylinder 1 is installed in the excavated foundation trench. The marker 2 corresponds to the coordinates of the marked point. Concrete is poured into the foundation trench for fixation. Several reinforcing rods 10 are inserted into the poured concrete to make the connection between the fixing cylinder and the concrete more secure. When the ground marker is needed for engineering surveying, the sealing cover 3 is rotated off, exposing the top of the marker 2 for use in engineering surveying of ground coordinates. Four sliding rail rods 4 are installed on the upper and lower sides of the inner wall of the fixing cylinder 1, and sliding sleeves 5 are slidably installed on the sliding rail rods 4. Each of the four upper sliding sleeves 5 is connected to a threaded rod 6 between each pair of opposite sliding sleeves. The two ends of the threaded rod 6 are connected to the sliding sleeves 5 on both sides. The threaded rod 6 is connected via a bearing. One end of the threaded rod 6 is also equipped with a locking sleeve. Rotating the locking sleeve allows it to contact and press against the sliding sleeve 5, locking the threaded rod 6 and the sliding sleeve 5 to prevent rotation. A rotating lever 11 is provided on the threaded rod 6. Threaded sleeves 7 are connected to the outside of both threaded rods 6, and the two threaded sleeves 7 are arranged in a cross shape, vertically, inside the marker rod 2. Each of the four sliding sleeves 5 on the lower side is connected to a sliding rod 8 in pairs. Positioning sleeves 9 are slidably mounted on each of the two sliding rods 8, and the two positioning sleeves 9 are arranged in a cross shape, vertically, inside the marker rod 2. The sliding connection between the sliding rods 8 and the positioning sleeves 9 assists in the rotation of the threaded rod 6. When rotating, the marker 2 has a stable lateral or longitudinal displacement. When the coordinate position of the marker 2 needs to be fine-tuned, the two threaded rods 6 can be rotated by rotating the lever 11. The threaded rods 6, through the connection with the inner threaded sleeve 7 of the marker 2, can drive the marker 2 to move laterally or longitudinally within the fixed cylinder 1, thereby achieving fine-tuning of the position of the marker 2 within the fixed cylinder 1. Multiple reinforcing rods 10 are installed outside the fixed cylinder 1, and the multiple reinforcing rods 10 are evenly distributed on the outer wall of the fixed cylinder 1. After the concrete is poured into the foundation trench, several reinforcing rods 10 outside the fixed cylinder 1 will be inserted into the poured concrete, making the direct connection between the fixed cylinder 1 and the concrete more secure.

[0024] The operational steps for this application are as follows:

[0025] The fixing cylinder 1 is installed in the excavated foundation trench, the marker 2 corresponds to the coordinates of the marked point, and concrete is poured into the foundation trench for fixing. Several reinforcing rods 10 will be inserted into the poured concrete to make the fixing cylinder 1 and the concrete more firmly connected. When the ground mark is needed for engineering surveying, the sealing cover 3 is rotated off and the top of the marker 2 is exposed for use in engineering surveying of ground coordinates.

[0026] When the coordinate position of the marker 2 needs to be fine-tuned, the two threaded rods 6 can be rotated by rotating the dial 11. The threaded rods 6, through their connection with the inner threaded sleeve 7 of the marker 2, can drive the marker 2 to move laterally or longitudinally within the fixed cylinder 1, thereby achieving fine-tuning of the position of the marker 2 within the fixed cylinder 1.
