Problems solved by technology

Although the existing test equipment can complete the test work, it is necessary to replace the entire assembly of the measuring head for each test item. Moreover, the device for clamping the geotextile is realized by tightening the bolts, which is laborious and laborious. And the force of the geotextile is not uniform, which affects the test results
In addition, for the test items of rigid foam and soft foam boards, that is, the test of pressure strength and fracture test, when changing the test items, it is necessary to replace a whole set of components, which is time-consuming, laborious and costly.

Abstract

The present invention relates to material test machine technology and is one geotextile strength test machine and its application. The test machine includes crossbeam, driving mechanism, test head, sensor module, microcomputerized controller, display, portal and pedestal. The upper holder for testing tensile strength and tear strength is set on the portal, and the lower holder is set on the crossbeam. The crossbeam with ends connected to the driving mechanism may be shifted inside the portal, and the test head and the sensor module are set on the crossbeam and connected together. There is elevated clamping unit set on the pedestal. The test head may be one of the CBR bursting test head, spherical bursting test head, piercing test head, plate material pressing test head and plate material breaking test head. The present invention may be used in complete various test jobs.

Description

(1) Technical field [0001] The invention relates to a geotextile strength machine and its application, and belongs to the technical field of material testing machines. (2) Background technology [0002] The shortage of water resources has become a major problem restricting economic development. People have adopted various measures to save water resources. Among them, the application of geosynthetics is an ideal method. In flood relief projects, the use of geosynthetics is very large. In order to make full use of the geosynthetic fabric, it is required to test the performance of the geosynthetic fabric, which gives people a new subject. Although the existing test equipment can complete the test work, each time a project is tested, the entire assembly of the probe must be replaced. Moreover, the device for clamping the geotextile is realized by tightening the bolts, which is laborious and laborious. In addition, the uneven force of the geotextile affects the test results. In additi...
