Construction device for submarine cable protection trench
The invention discloses a construction device for a submarine cable protection trench, and belongs to the technical field of underwater structures, the construction device comprises a water inlet pipe and a pump connected with a top flange of the water inlet pipe, the inner side of the bottom of the water inlet pipe is coaxially and fixedly connected with a suction pipe, and the front end and the tail end of the suction pipe extend out of the water inlet pipe; the tail end of the suction pipe is sequentially, coaxially and fixedly connected with a suction chamber, a throat pipe and a diffusion pipe, a nozzle is arranged on the outer side of the suction pipe in a surrounding mode, the front end of the nozzle is fixedly connected to the side face of the bottom of the water inlet pipe, and the tail end of the nozzle is fixedly connected to the front end of the suction chamber. And when the design flow and lift of the pump meet the actual engineering requirements, the sizes of the suction pipe and the throat pipe are increased to the maximum extent, the mudstone accumulation problem of the construction device in the construction process is prevented, and the construction progress of the protection ditch is ensured.
本发明公开了用于海底电缆保护沟的施工装置，属于水下结构技术领域，包括进水管以及与进水管顶部法兰连接的泵，进水管底部内侧同轴固定连接有吸入管，吸入管前端与末端均延伸出进水管，吸入管末端依次同轴固定连接有吸入室、喉管与扩散管，吸入管外侧环绕设置有喷嘴，喷嘴前端固定连接在进水管底部侧面，喷嘴末端固定连接在吸入室前端，本装置其优点在于，通过对施工装置的结构参数取值，并进行CFD数值模拟，在保证泵设计流量与扬程满足实际工程需求时，最大化增加吸入管和喉管的尺寸，防止施工装置在施工过程中出现泥石堆积问题，确保保护沟施工进度。
