[0044] like Figures 1 to 4 As shown in the figure, this application provides a sunken weighbridge, including: a pit, a base layer 1, a concrete foundation, load cells, and a weighing platform (not shown). The base layer 1 is laid in the pit, and the concrete foundation is set on the base layer 1. The concrete foundation includes a main body 21 and a platform 22 located at the edge of the main body 21. Anti-deviation components 3 are provided on the side wall of the platform 22. The load cells are set in the main body 21 and located within the enclosed area of ​​the platform 22. The weighing platform is supported on each of the load cells and located inside the platform 22. There is a gap between the anti-deviation component 3 and the weighing platform.

[0045] The sunken weighbridge provided in this application effectively avoids the problem of road space occupation by surface weighbridges, especially in narrow construction roads or factory roads, maximizing vehicle driving space. The sunken weighbridge of this application is equipped with multiple anti-deviation components 3, which limit the weighing platform and prevent serious deviation.

[0046] In some possible implementations, the anti-deviation component 3 includes a crash barrier 31 and a first fixing part 32. The first fixing part 32 is embedded in the baffle 22, and the crash barrier 31 protrudes from the side wall of the baffle 22. The crash barrier 31 and the first fixing part 32 are fixedly connected. The small distance between the crash barrier 31 and the weighing platform can limit the movement of the weighing platform, prevent collisions, and prevent deviation.

[0047] In some possible implementations, the sunken weighbridge includes corner protectors 5. The platform 22 has sharp edges, and the corner protectors 5 are connected to and cover the sharp edges of the platform 22. The corner protectors 5 protect the edges of the platform 22, preventing them from being easily crushed by vehicles and thus improving the quality of the weighbridge.

[0048] In some possible implementations, the corner protector 5 includes an angle steel 51 and a second fixing part 52 connecting the angle steel 51. The second fixing part 52 is embedded in the baffle 22. The angle steel 51 covers the corner of the baffle 22. The angle steel 51 and the second fixing part 52 are fixedly connected.

[0049] The angle steel 51 comprises two vertically connected steel plates, with the second fixing part 52 located between the two steel plates and connected at the included angle. The two steel plates respectively cover the surfaces on both sides of the edge of the platform 22.

[0050] In some possible implementations, foundation reinforcement is provided in the concrete foundation, and the first fixing part 32 and the second fixing part 52 are both welded to the foundation reinforcement, thereby enhancing the connection stability of the embedded parts and making the concrete foundation more integrated.

[0051] In some possible implementations, a plurality of positioning embedded parts 6 are provided on the main body 21, and the weighing sensor is fixed on the positioning embedded parts 6.

[0052] The main body 21 is provided with multiple bosses 211. The positioning embedded part 6 has a positioning plate 61 and a third fixing part 62 connecting the positioning plate 61. The positioning plate 61 covers the top end face of the bosses 211, and the third fixing part 62 is located inside the bosses 211. The load cell can be fixed on the positioning plate 61.

[0053] In some possible implementations, the sunken weighbridge includes a water collection tank 7 located on one side of the concrete foundation, the upper surface of which forms a slope extending towards the water collection tank 7.

[0054] In some possible implementations, the sunken weighbridge includes a buried waterproof sleeve 8, through which cables connecting each weighing sensor are run, and the waterproof sleeve extends from the concrete foundation to the power supply equipment.

[0055] In this embodiment, the concrete foundation can be poured with concrete of strength not less than C30 and reinforced with double-layer bidirectional reinforcement. The standard weighbridge is configured according to the weighing requirements. The anti-deviation component 3, corner guard 5 and positioning embedded component 6 can be made of steel components with strength not less than Q335. The water collection tank 7 can be in a standard or prefabricated form. The buried waterproof sleeve 8 should be a rigid plastic pipe with a certain strength and should not be a flexible hose.

[0056] The construction process for this sunken weighbridge system is as follows: Embedding of pre-embedded parts (anti-deviation parts 3, corner protectors 5, and positioning pre-embedded parts 6) → Weighbridge foundation pouring → Foundation slope finding → Installation of the water collection tank 7 → Weighing platform installation → Cable burial. The requirements for each construction step are as follows:

[0057] (1) Embedded parts: When binding the foundation steel bars of the weighbridge, each embedded part is embedded. Among them, the positioning embedded part 6 serves as the support surface of the weighbridge load cell. Its flatness must be controlled within ±3mm, otherwise the weighing data deviation is likely to occur. The anti-collision steel plate 31 of the anti-deviation part 3 can be made of anti-collision steel plate 31 with a thickness of not less than 3mm. The corner guard 5 can be made of angle steel 51, which plays the role of limiting, anti-collision and anti-deviation. During the embedding, the embedded parts are fixed according to the layout points of the weighbridge foundation. All the positioning ribs on the inner side of the embedded parts (first fixing part 32, second fixing part 52 and third fixing part 62) are spot welded to the foundation steel bars.

[0058] (2) Weighbridge foundation pouring: Before pouring the weighbridge foundation, the position of the embedded parts needs to be checked, especially the elevation, to avoid deviations in the data transmission of the weighing sensor due to elevation deviations. During the foundation pouring process, the position and frequency of concrete vibration need to be controlled to reduce disturbance to the embedded parts.

[0059] (3) Foundation slope: After the concrete is vibrated, the foundation of the weighbridge is finished. The structure is sloped at 1%-1.5% towards the side where the water collection tank 7 is installed, and the slope is directed towards the drainage pipe. After the slope is finished, the foundation is cured as required.

[0060] (4) Installation of water collection tank 7: Leave a pit at the installation location of water collection tank 7, build a brick formwork with concrete bricks, and ensure that the inner dimension of the brick formwork is slightly larger than the body of water collection tank 7, and then install the matching drainage device.

[0061] (5) Weighing Platform Installation: When installing the weighing platform, first fix the load cells. The load cells are bolted to the positioning embedded parts 6, and leveled using a level to control the flatness within ±2mm. To improve the waterproof effect of the load cell base, apply waterproof sealant around each base after leveling. The standardized weighing platform is hoisted into the slot above the load cell using a truck crane or other mechanical equipment via a four-point lifting method, and then leveled a second time using a level.

[0062] (6) Cable laying: All weighbridge power lines are laid underground using waterproof conduits. The waterproof conduits are buried slightly deeper than the weighbridge foundation and pass through the weighbridge room foundation to connect to the power supply equipment. When inspecting or replacing cables, it is only necessary to pull the cables out of the conduits, which is convenient for maintenance.

[0063] The concrete foundation drainage method can adopt two-sided drainage as needed, and two collection pools should be set up accordingly. The thickness of the concrete foundation should be controlled not less than 150mm to improve the rigidity of the foundation. Welding of embedded parts should be reduced, and the welding strength of steel plates, angle steel and positioning bars should be ensured.

[0064] The preferred embodiments disclosed above are merely illustrative of this application. The preferred embodiments do not exhaustively describe modifications and variations. These embodiments are selected and specifically described in this specification to better explain the principles and practical applications of this application, thereby enabling those skilled in the art to better understand and utilize this application. This application is limited only by the claims and their full scope and equivalents.
