Device and method for testing toughness of airport runway foundation bearing capacity

Abstract

The invention relates to the technical field of foundation bearing capacity detection, especially a toughness detection device and method for airport runway foundation bearing capacity, including a main body device, a first fixed point device, a second fixed point device, a detection device and an antirust device. The main body device The inner side of the left end of the main body is fixedly connected with a first pointing device, and the inner side of the top end of the main body device is fixedly connected with a second pointing device. In the present invention, through the set second pointer, etc., when it is necessary to detect the bearing capacity of the foundation through the probe rod , through the function of the second connecting plate, the main body of the detector can be driven to move down automatically, which saves physical strength, and ensures that the main body of the detector will not be skewed during detection. When not in use, wipe off the soil on the surface of the probe rod, and then put it inside the corresponding oil-absorbing cotton, and use the butter on the oil-absorbing cotton to realize the anti-rust of the probe rod, so as to ensure that the probe rod will not rust when not in use .

Description

technical field [0001] The invention relates to the technical field of foundation bearing capacity detection, in particular to a toughness detection device and method for airport runway foundation bearing capacity. Background technique [0002] The bearing capacity of the foundation refers to the ability of the foundation to bear the load. Under the action of the load, the foundation will deform, and as the load increases, the deformation of the foundation will gradually increase. , when the load increases to a point in the foundation or the shear stress of each point in a small area on a plane in a certain direction reaches the shear strength of the soil, the point or each point in a small area will be sheared and damaged. In the limit equilibrium state, the stress in the soil will be redistributed. Most of the limit equilibrium state of the foundation in a small range can be restored to the elastic equilibrium state. The foundation can still tend to be stable and still hav...

Problems solved by technology

[0003] When testing the bearing capacity of the foundation, according to the different detection methods, the foundation will be treated in different ways, and the detection points need to be confirmed in different ways. The general foundation detector does not have the function of confirming the detection points, and the general The foundation detector needs to be manually pressed down on the foundation detector, which is time-consuming and laborious, and it is not easy to use, and it is easy to make the foundation detector skew during the pressing process, and the general probe rod is prone to rust when not in use, which affects The post-use of the probe rod, therefore, a toughness detection device and method for the bearing capacity of the airport runway foundation are proposed to address the above problems
