HDPE双壁波纹管怎么回填压实​

2025-08-19

HDPE双壁波纹管以其优异的环刚度、抗冲击性和耐腐蚀性能,在市政排水、排污、通信等领域得到广泛应用。公元管道作为优质HDPE双壁波纹管的提供者,深知科学合理的回填压实是确保管道系统长期稳定运行的关键环节。正确的回填不仅能保护管道免受外部荷载损伤,还能充分发挥其结构性能,延长使用寿命。

在进行公元管道HDPE双壁波纹管回填压实前,首先要确保沟槽内无积水、无杂物,管道安装稳固,接口严密无渗漏。对沟槽底部进行检查,确保其平整度和承载力符合设计要求,必要时进行地基处理。

回填材料的选择至关重要。应优先选用颗粒级配良好的中粗砂、砾石、碎石屑或开挖出的合格原土(需去除大于50mm的石块、砖块及其他有害物质)。回填土的含水量应控制在最佳压实含水量范围内,以保证压实效果。对于公元管道HDPE双壁波纹管,尤其要避免使用含有尖锐棱角、大块硬物或冻土块的回填材料,以防损伤管道外壁。

回填应分层进行,每层虚铺厚度不宜超过300mm(具体厚度需根据压实机械类型进行调整)。从管道两侧对称同时回填,确保管道不产生位移或变形。对于管底至管顶以上500mm范围内的回填土,必须采用人工或小型压实机械进行夯实,严禁使用大型机械直接碾压管道。这一区域被称为“核心回填区”,对管道的保护至关重要,其压实度应达到设计及规范要求(通常不低于95%)。

压实过程中,应注意控制压实机械的行驶速度和碾压方向,避免对管道造成冲击。对于不同的回填层,应选择合适的压实工具,如轻型压路机、平板振动夯、蛙式打夯机等。每一层回填土都必须经检验合格后方可进行下一层回填。

管顶500mm以上的回填,可以采用机械碾压,但碾压速度不宜过快,且应从沟槽两侧向中心进行。回填至设计高程后,其表面应略呈拱形,以利于排水。

整个回填压实过程中,应严格按照施工规范和设计要求进行质量控制,加强现场巡查和检测。通过科学的回填压实,能够有效保护公元管道HDPE双壁波纹管,确保其在长期使用中保持良好的结构稳定性和过水能力,为工程质量提供坚实保障。
