A composite foundation bearing capacity detection device and detection method

Abstract

The invention relates to the technical field of composite foundation bearing capacity, and discloses a composite foundation bearing capacity detection device, which includes a base plate, and pressure gauges and automatic telescopic parts are fixedly installed on the left and right sides of the upper surface of the base plate. The bottom of the front of the load cell is fixedly connected with a support column, and the middle part of the upper surface of the base plate is provided with a fixing seat, and the two load cells are respectively clamped with one side of the adjacent fixing seat through a limit rod, so that The middle part of the front of the fixed seat is fixedly equipped with a device leveling calibrator, and the top of the fixed seat is provided with a pressure transmission block. The device for testing the bearing capacity of the composite foundation is convenient to check and correct whether the device is located in the horizontal plane through the device leveling calibration device, so as to prevent the detection device from being one of the horizontal planes to measure the conforming foundation, and prevent human factors from testing the bearing capacity of the composite foundation. The impact caused by the measurement results of the device improves the measurement accuracy of the composite foundation bearing capacity detection device.

Description

technical field [0001] The invention relates to the technical field of composite foundation bearing capacity, in particular to a composite foundation bearing capacity detection device and detection method. Background technique [0002] Composite foundation means that part of the soil of the natural foundation is strengthened or replaced during the foundation treatment process, or reinforcement materials are set in the natural foundation, and the reinforcement area is composed of the matrix (natural foundation soil or improved natural foundation soil) The artificial foundation composed of two parts, the base body and the reinforcement body, under the action of load, the base body and the reinforcement body jointly bear the load. The bearing capacity of the foundation is the bearing potential of the unit area of ​​the foundation soil as the load increases. The common unit is KPa, which is the basis for evaluating the foundation. The comprehensive terms of stability, it should ...

Problems solved by technology

[0003] The shear strength theory of soil is the theoretical basis for studying and determining the bearing capacity of the foundation. Before the detection of the existing foundation bearing capacity detection device, it is not checked and corrected whether the position of the measurement device is parallel to the bottom surface, and then it is easy to make the detection The pressure measured by the device is decomposed by other forces, which makes the measured structure inaccurate, and when the existing detection device detects a foundation with a large bearing capacity, the operator is likely to have an impact on human health due to excessive force. Therefore, we propose a composite foundation bearing capacity detection device and detection method
