塑料排水检查井施工技术

Construction technology of plastic drainage inspection well

近几年,随着塑料排水管在市政道路雨污排水、小区室外雨污排水系统中的推广运用,塑料排水管已成为市政道路、小区排水管网中的主流管道,对市政道路、室外排水工程质量的提升起到了很大作用。也由于传统的砖砌检查井存在内渗外漏的问题，对地下水资源造成污染，多地政府已限期禁止砖砌检查井，取而代之的塑料成品检查井防渗性能好、绿色、环保、节能、节地等诸多优势。塑料成品检查井其施工进度快，节省人工，减少施工安全隐患。

In recent years, with the promotion and application of plastic drainage pipe in municipal road and sewage drainage and outdoor sewage drainage system, plastic drainage pipe has become the mainstream pipe in municipal road and district drainage pipe network, which has played a great role in improving the quality of municipal roads and outdoor drainage projects. Because of the problem of leakage of internal seepage in the traditional brick inspection well and the pollution of groundwater resources, many governments have banned brick inspection wells for limited time, and they have many advantages, such as good anti-seepage performance, green, environmental protection, energy saving and land saving. The plastic product inspection well has a fast construction speed, saves labor and reduces construction safety risks.

塑料排水检查井施工技术通过优化塑料井盖及其基础，使塑料排水检查井得以应用到工程中，使得塑料排水检查井的零渗漏、减少安全隐患、施工进度快、适用性广、使用年限久的作用达到预期的效果。

The plastic drainage inspection well construction technology can be applied to the project by optimizing the plastic shaft cover and its foundation, making the plastic drainage check well to be applied to the project. It makes the plastic drainage check the well's zero leakage, reduces the hidden danger of safety, the construction progress is fast, the application is wide and the service life is long.
