一、选择优质的产品及配套管材。塑料检查井是按照国标尺寸生产的，可是市场上管材的品质参差不齐，井座胶圈的厚薄要适中。
1. Choose high-quality products and matching pipes. Plastic inspection wells are manufactured in guangdaon.37ix.com.cnchoushag.37ix.com.cn jiaoni.07858.netbuxiugang.37ix.com.cntuoliutayq.37ix.com.cn zujuji.37ix.com.cnaccordance with the national standard size, but the quality of pipes on the market is uneven, and the thickness of the well seat apron should be moderate.
二、按照规范施工
2. Construction in accordance with specifications
塑料检查井井座与管道连接安装顺序：先从接户管上游段开始安装，以井-管-井-管顺序安装，并逐渐向下游支管，干管延伸。
Installation sequence of connection between wellbore and pipeline in plastic inspection wells: first, from upstream section of nozzle, install in sequence of well-pipe-well-pipe, and gradually extend to downstream branch pipe and trunk pipe.
三、建议选择塑料井和管道是统一厂家的，配套问题可以更好地解决。
3. It is suggested that the selection of plastic wells and pipes should be made by a unified manufacturer. Matching problems can be better solved.
