摘要
为了保证排水系统的正常运行,避免漂浮物通过溢水井进入排水管(或隧洞)而发生堵塞,提出在溢水井外围设置护栏的方法。对于护栏防护装置,以实例给出具体材料的规格和尺寸大小,以及装置的基本原理和装置对排洪量的影响。论证排水系统设置护栏的必要性,并从护栏装置的角度提出溢水井设计的基本要求。
A method of setting barrier device is presented to ensure normal operation of drainage system and avoid blocking,which is caused by floating objects passing into drain pipes or tunnels through drain wells.The specification and material size of barrier device are given in the practical examples,meanwhile,essential theory of the equipment and influence on drainage volume are analyzed.What is demonstrated in the final is not only the necessity of setting barrier device but also the basic requirements of drain wells design.
