Ground Strength Measuring Device Setting Height Test Pole

Abstract

The invention provides a ground intensity measurement device with a height test bar. The ground intensity measurement device is characterized in that the height test bar used together for integral measurement is arranged on one side of a hydraulic cylinder under which a measurement probe is arranged, the other side of the hydraulic cylinder is connected with a pressure sensor, and the hydraulic cylinder is equipped with a hydraulic packet for providing hydraulic power. Owing to the arrangement, when the ground intensity measurement device is in use, error data caused by overall uplifting due to an excessively intensive ground can be collected by the height test bar to supplement and correct overall measurement data.

Description

technical field [0001] The invention relates to a ground strength measuring device, in particular to a ground strength measuring device provided with a height test rod. Background technique [0002] Before the reconstruction of roads and railways, first measure the strength of the ground to determine and design the bearing strength of the ground. Due to the lack of special measuring devices, in general, jacks are used to load the penetration rod to measure the penetration As well as the load weight to calculate the bearing value of the ground strength, and this traditional method will inevitably lead to inaccurate calculation of the jack pressure due to the difference in the tip of the penetrating rod end, the difference in the thickness of the rod body, and other factors. Obtain ground strength data. In 2006, the company proposed a technical solution for ground strength measuring devices. For the first time, hydraulic cylinders were used to conduct scientific calculations t...

[0002] Before the reconstruction of roads and railways, the strength of the ground is first measured to determine and design the bearing strength of the ground. Due to the lack of special measuring devices, in general, a jack is used to load the penetration rod to measure the penetration And the load weight, in order to calculate the bearing value of the ground strength, and this traditional method will inevitably lead to inaccurate calculation of the jack pressure due to the difference in the tip of the penetrating rod end, the difference in the thickness of the rod body, and the inaccurate calculation of the jack pressure. Obtain ground strength data. In 2006, the company proposed a technical solution for ground strength measurement devices. For the first time, hydraulic cylinders were used to conduct scientific calculations through pressure, which can obtain more scientific and accurate data. Since it is installed on the girder of the vehicle chassis, it is mainly used for load For heavier models, and for small vehicles, such as off-road vehicles, during the test process, the measuring device may be lifted up and cannot be measured accurately, so that there is a defect that the accurate integer data cannot be obtained and the test data is inaccurate
