Description

Technical Field

[0001] The utility model belongs to the technical field of foundation detection equipment, and in particular relates to a foundation pressure detection device. Background Art

[0002] Foundation testing is an indispensable part of the infrastructure construction process. The bearing capacity of the foundation is directly related to the overall construction quality and safety of the building. Whether the bearing capacity of the foundation can be fully and effectively utilized, the foundation refers to the soil or rock supporting the foundation under the building. The soil layer serving as the foundation of the building is divided into rock, gravel soil, sand, silt, clay and artificial fill. The natural foundation is a natural soil layer that does not require human reinforcement.

[0003] After searching, the Chinese utility model patent application document with Chinese patent authorization announcement number CN220035374U discloses a foundation pressure detection device, including a fixed plate. When working, the fixed rod on the telescopic rod at different positions is moved to adjust it to a horizontal position, and the adjustment is made by observing the spirit level. After the adjustment is completed, the rotating rod and the fixed rod are fixed with a fixing bolt, and then the power rod is lifted to drive the heavy hammer to move upward, and then the power rod is loosened, so that the heavy hammer falls downward under the action of gravity and hits the pressure block, and the pressure block pushes the probe rod to hit the foundation. After the detection is completed, the fixing bolt is loosened, the fixed rod is put into the rotating rod, and then the rotating rod is rotated to close to the sleeve, so that the card block is engaged with the card slot, thereby reducing the volume of the device.

[0004] In response to the above-mentioned related technologies, the device lifts the power rod to drive the weight to move upward, and then releases the power rod, so that the weight falls downward under the action of gravity and hits the pressure block, and the pressure block pushes the probe rod to hit the foundation. During the detection, the pressure block pushes the probe rod to hit the foundation, and effective pressure detection cannot be performed. Therefore, it is urgent to design a foundation pressure detection equipment to deal with these problems. Utility Model Content
