防波堤

Back of the breakwater the dredger was working.

在防波堤后面挖泥船正在作。

They riprapped the breakwater with stone.

他们以乱石基巩固防波堤。

The project department monitors and controls the whole process of breakwater enrockment costruction by field observing instruments buried in sand soft nappe.

通埋设在软体排上的原形观测器,对防波堤抛石施进行了全监测。
