Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering foundation detection, in particular to a fixing device for construction engineering foundation detection. Background Art

[0002] The foundation refers to the soil or rock supporting the base of a building. The soil layers serving as the foundation of a building are divided into rock, crushed stone soil, sand, silt, clay and artificial fill. There are two types of foundations: natural foundations and artificial foundations (composite foundations). Natural foundations are natural soil layers that do not require human reinforcement, while artificial foundations require human reinforcement. Common ones include stone chip cushion layers, sand cushion layers, mixed ash soil backfill and compaction, etc.

[0003] The existing patent CN214219762U proposes a foundation detection device for quality inspection of housing construction projects. The utility model includes a base plate and a foundation hardness detection component. The front part of the base plate is provided with a cavity running through the upper and lower parts. The outside of the cavity is provided with a protective frame fixed to the upper surface of the base plate. The foundation hardness detection component is fixed in the protective frame and the bottom extends to the inside of the cavity. The foundation hardness detection component includes a pressure electronic scale, a hydraulic telescopic rod and a hardness detection rod. The pressure electronic scale and the hardness detection rod are correspondingly installed at the top and bottom of the hydraulic telescopic rod.

[0004] However, although the existing patent CN214219762U can detect the ground hardness by the size of the pressure by setting up a pressure-sensing ground hardness detection mechanism, and sets up a ground flatness detection mechanism in the device, which solves the problem that the current device cannot quickly complete the ground hardness detection and flatness detection, the user may need to adjust the height of the device according to the environmental differences of the road surface.
