Toughness detection device and method for airport runway foundation bearing capability

Abstract

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 capability. The device comprises a main body device, a first point determining device, a second point determining device, a detection device and a rust prevention device, wherein the first point determining device is fixedly connected to the inner side of the left end of the main body device, and the second point determining device is fixedly connected to the inner side of the top end of the main body device. According to the toughness detection device, through the arrangement of a second pointer and the like, when the foundation bearing capacity needs to be detected through probe rods, a detector main body canbe driven to automatically move downwards through the action of a second connecting plate, the physical strength is saved, it is ensured that the askew phenomenon of the detector main body cannot occur during detection, through the arrangement of a storage shell, oil absorbent cottons, and the like, soil on the surfaces of the probe rods are wiped clean when the probe rods are not in use, and then the probe rods are placed in the inner sides of the corresponding oil absorbent cottons, so that the rust prevention of the probe rods is realized through butter on the oil absorbent cottons, and itis ensured that the probe rods cannot 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
