runnel

Ancient girders girders creak and groan , ropes tighten and then a trickle of oil oozes oozes down a stone runnel into a used petrol can.

古木大梁压得嘎吱作响，缆索开始绷紧，接着便见一滴滴的油沿着一条石槽流入一只废旧汽油桶里。

They used waterproof cement to prevent water from seeping through the roof of the runnel .

他们用防水水泥来防止水从屋顶的排水通道里渗透。
