Description

A foundation detection device for construction projects

Technical field

The utility model relates to the technical field of construction engineering, specifically a foundation detection device for construction engineering.

Background technique

The foundation bearing capacity is the bearing potential exerted by the unit area of the foundation soil as the load increases. The commonly used unit is KPa, which is a comprehensive term for evaluating the stability of the foundation. It should be pointed out that foundation bearing capacity is a practical professional term proposed for foundation design to facilitate the evaluation of foundation strength and stability, and is not an indicator of the basic properties of soil.

The patent document that has been published with the announcement number CN213897064U discloses a foundation load strength detection device for construction projects, which includes a frame. One end of the frame is equipped with a reduction motor, and the rotor shaft of the reduction motor is equipped with a threaded rod. There is a nut threaded on the threaded rod, and a clamping pipe is installed on the lower surface of the nut. A clamping groove is provided on the clamping pipe. One end of the threaded rod unscrews the nut and is inserted into the clamping groove. A weight is installed on the lower surface of the clamping pipe. The frame A support plate is installed on the inner sliding surface. A load sensor is installed on the support plate. A detection rod is installed on the lower surface of the support plate. The reduction motor is started through the control panel to drive the threaded rod to rotate, causing the nut to move downward along the threaded rod, and the nut drives the clamp. The tube moves downward, causing the weight to squeeze the load sensor downward, pushing the probe at the bottom of the detection rod to drill into the foundation. The load sensor will sense the load and transmit it back to the control panel, and calculate it based on the observation of the scale on the detection rod. The operation steps are simple and safer.

The above devices can well detect the bearing capacity of the foundation, but do not use inspectors to record the bearing capacity data of the foundation, which results in inaccurate recorded data and affects the judgment of the bearing capacity of the foundation.
