AI Technical Summary

Technical Problem

Existing concrete testing equipment for road and bridge construction cannot simultaneously simulate structural loads and water pressure, resulting in discrepancies between test data and actual service conditions. Furthermore, multiple devices are required to complete mechanical and impermeability tests in stages.

Method used

A concrete testing device for road and bridge construction was designed. It simulates concrete being subjected to structural loads and water pressure simultaneously through a liquid storage tank and a pressure application component. Combined with a transmission component, it achieves synchronous testing. The device includes a liquid storage tank, a pressure application component, a transmission component, and a pressure sensor, enabling simultaneous testing of the compressive strength and impermeability of concrete.

Benefits of technology

This has improved the comprehensiveness and reliability of concrete testing, shortened the testing cycle, reduced liquid waste, and enhanced the convenience of testing operations and the accuracy of data.
