Abstract
ABSTRACT The revised abstract is as follows:As a new waterproof system with plastic in underground silos, three kinds of polypropylene plastic welds were designed and subjected to a water-pressure resistance test in pump-pressure mode. The failure modes, stress processes, failure mechanisms, and influencing factors of different weld forms with different thicknesses were studied. The water-pressure resistance on the groove-weld specimens with welded cover plates was increased by approximately 40%–85% compared with that of the groove-weld specimens. The water-pressure resistance for groove-weld specimens with pasted and welded cover plates was increased by approximately 10% compared with that of the groove-weld specimens with welded cover plates. The depth of the designed underground silos is generally lower than 35 m, and the 8-mm plate thickness and groove-weld specimens with welded cover plate combination can resist 58.16 m of water pressure with a recommended safety factor of 1.66.
期刊介绍：
Plastics, Rubber and Composites: Macromolecular Engineering provides an international forum for the publication of original, peer-reviewed research on the macromolecular engineering of polymeric and related materials and polymer matrix composites. Modern polymer processing is increasingly focused on macromolecular engineering: the manipulation of structure at the molecular scale to control properties and fitness for purpose of the final component. Intimately linked to this are the objectives of predicting properties in the context of an optimised design and of establishing robust processing routes and process control systems allowing the desired properties to be achieved reliably.
