Description

Technical Field

[0001] This utility model relates to the field of landmark fixing device technology, and more specifically, to a fixing device for embedding anti-settlement engineering survey control point marker stones. Background Technology

[0002] Land boundary markers are permanent markers that define the scope of land ownership and clarify the location of boundaries. Their core function is to fix land boundaries and avoid ownership disputes. They must be resistant to settlement, damage, and easy to identify. The core reasons for the settlement of land boundary markers are changes in the soil environment, defects in the design and construction of the markers themselves, as well as external loads or environmental influences, which cause the relative position of the markers and the soil to shift downwards.

[0003] As a fixed structure for the installation of benchmarks, engineering surveying control points need to have good anti-settlement performance. Existing anti-settlement control points are generally planar and apply force vertically. Therefore, the weight of the benchmark itself acts directly vertically downwards into the soil below. This makes the benchmark more prone to settlement when located above soft soil, affecting its usability. In view of this, we propose a settlement-resistant fixing device for the installation of engineering surveying control point benchmarks. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a fixing device for the installation of anti-settlement engineering measurement control point marker stones, so as to solve the technical problem that the vertical force of the current marker stone fixing device is prone to cause settlement.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a fixing device for burying anti-settlement engineering survey control point marker stones, including a marker stone, a side shell, and a bottom frame. An assembly box is inserted into the middle of the bottom frame, and an arch-shaped pressure plate is provided in the lower opening of the assembly box. The bottom of the marker stone is provided with an insertion end that can be inserted into the assembly box. The side shell is slidably inserted into the openings on both sides of the bottom frame. The side shell is composed of a vertical plate and an inclined plate, and a clamping opening is formed at the included angle. A transverse side flow port is opened on the inclined plate of the side shell, and pressure blocks are symmetrically distributed on the inner side of the vertical plate of the side shell.

[0006] Preferably, the assembly box is divided into an upper fixing cavity and a lower filling cavity by an arc pressing plate, and the insertion end of the marker stone is inserted into the fixing cavity after passing through the insertion port.

[0007] Preferably, the insertion end at the bottom of the marker stone is toothed and the insertion end is adapted to the insertion port, and the side wall of the marker stone fits into the insertion port to complete the limiting.

[0008] Preferably, an assembly opening is provided in the middle of the bottom frame, the assembly box is trapezoidal, and the inclined surfaces on both sides of the assembly box are limited to fit the assembly opening.

[0009] Preferably, the bottom frame is C-shaped, and the bottom frame and the side shell form a casting cavity. The assembly box is located inside the casting cavity. The bottom frame has a mating interface on both sides, and an anchor rod is inserted into the mating interface. The top of the anchor rod is located inside the mating interface, and the lower end of the anchor rod is inserted into the pre-embedded foundation pit.

[0010] Preferably, the upper end of the pressure block is attached to the bottom of the base frame, and the outer side of the pressure block is provided with a downwardly inclined pressure surface.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses the side shell and assembly box to support the bottom surface. The soil sinks into the opening of the assembly box and fits against the lower arc surface of the arc pressure plate. The arc pressure plate cooperates in bearing the weight. The weight of the marker stone is vertically downward. The arc surface of the arc pressure plate disperses the weight outward. The arch bridge-shaped surface can transfer the weight of the marker stone itself and the load above to the soil on both sides, avoiding soil compression deformation caused by concentrated force on a single flat plate. It is especially suitable for soft soil and loose soil. With the inclined pressure surface of the pressure block, the vertical gravity is converted to the outside, further improving the anti-settlement effect.

[0012] 2. The modular design of this utility model facilitates assembly. The assembly box is inserted from the bottom of the assembly opening and is limited by the inclined surface. The clamps formed at the bends of the two side shells slide onto the two sides of the bottom frame, forming a casting cavity inside the device. The anchor rod is inserted into the pre-embedded pit, and the top of the anchor rod is inserted into the mating interface. The bottom insertion port of the marker stone is placed into the upper side of the mating arc pressure plate. The device is placed into the pre-embedded pit, and cement is filled into the casting cavity. After filling, the device forms a whole. The casting method reduces the weight of the fixed components and accessories, making it easy to transport and assemble, while ensuring connection strength and service life.
