In the engineering construction, a large number of metal corrugated pipes are used, particularly for precast beams, in the prestressed part of the precast beams, prestressed steel strands need to pass through the corrugated pipes, when the strength of concrete reaches a certain strength, the prestressed steel strands are tensioned, grouting is needed after tensioning is finished, and finally, the precast beams are closed, so that each precast beam needs the corrugated pipe. Therefore, the quality of the metal corrugated pipe directly influences the building safety of the bridge, and the standard can not well adapt to the requirement of new technology development due to the lack of systematic test basis and mature engineering experience summary.
The impervious test method of the metal corrugated pipe allows the irrigation method to be adopted for the impervious test of the impervious performance test piece after bearing concentrated load, and the grouting test can be continuously adopted when the irrigation test has water seepage, thereby facilitating the test.
