在地质条件特别恶劣的某些山区(如石漠化地区),当不能找到适宜的管沟换填土的情况下,需要开发一种抗冲击性能强且便于施工的材料,包裹在管道外层,以代替细土回填。该材料能抵抗碎石块坠落对管线及防腐层的冲击,从而保护管道和PE防腐层。新材料各原料性质直接影响新材料的保护性能,因此对这种山区石油管道新型保护材料的一些配方原料对其抗冲击性能影响展开研究十分必要。在对各原料调研基础上,采用单因素试验方法,确定各原料在试验中的用量范围,并按该方案逐个制造新型复合材料试验模型,再对新材料模型做冲击试验。根据试验结果,分析各原料对新材料冲击性能的影响,以期获得抗冲击性能优良的新型复合保护材料。
In some mountainous areas where the geological conditions are extremely poor (such as in rocky desertification areas), where it is not possible to find suitable pipe-drencher for earth fill, there is a need to develop a strong impact-resistant and easy-to-construct material that is wrapped around the outer layer of the pipe , Instead of fine soil backfill. The material is able to withstand the impact of gravel falling on the pipeline and the coating, thereby protecting the pipe and PE coating. The material properties of new materials directly affect the protective properties of new materials. Therefore, it is necessary to study the impact of some formulated raw materials of new protective materials in such mountainous oil pipelines on its impact resistance. Based on the investigation of each raw material, the single-factor test method was used to determine the range of the amount of each raw material used in the experiment. According to the scheme, a new composite material test model was made one by one, and then a new material model was tested. According to the test results, the impact of each raw material on the impact properties of new materials was analyzed in order to obtain a new composite protective material with excellent impact resistance.
