雨水口的施工
Construction of rainwater inlet
1、改移雨水口位臵
1. Relocation of rainwater inlet
(1)将现况位于道路中央的雨水口改移至路缘石处
(1) The gutter inlet in the middle of the road is moved to the curb
先将现况位于道路中央的雨水箅和井圈拆除并将雨水口内的杂物清理干净,再用C15快硬砼填实至现况路面,在砼顶面拉毛,最后随同道路施工铺设面层沥青砼;与废弃的雨水口位臵对应,在路缘石处新建偏沟式雨水口,其雨水管下游接入位臵同原雨水口,新建雨水箅数量不少于废弃雨水口的篦子数量。雨水管须进行C20快硬砼满包加固处理。
Firstly, the rainwater grates and well rings in the center of the road are removed, and the debris in the inlet is cleaned up. Then, C15 rapid hardening concrete is used to fill the existing road surface, roughen the top surface of the concrete, and finally pave the asphalt concrete along with the road construction. Corresponding to the abandoned rainwater inlet, a new side ditch type rainwater inlet is built at the curb, and the downstream connecting position of the rainwater pipe is the same as the original one The number of grates shall not be less than that of abandoned inlets. The rainwater pipe must be reinforced with C20 fast hardening concrete.
(2)将现况位于道路中央的雨水口改造为检查井
(2) The existing rainwater inlet in the middle of the road is transformed into an inspection well
先将现况位于道路中央的雨水口拆除,再在原位臵新建Φ1000mm圆形砼雨水检查井,最后将附近新建雨水口接入新建的检查井。
Firstly, the rainwater inlet located in the center of the road is removed, and then a Φ 1000mm circular concrete rainwater inspection well is built in situ. Finally, the new rainwater inlet nearby is connected to the new inspection well.
