Underwater excavating dredging device and construction method thereof
The invention discloses an underwater excavating dredging device and a construction method thereof. The underwater excavating dredging device comprises a mud suction mechanism and a high-pressure flushing mechanism. The mud suction mechanism comprises a mud suction pipe, an expansion cavity, a mud suction pipe head and a drill bit, wherein the upper end of the mud suction pipe is connected with an impact type driving device, the lower end of the mud suction pipe is connected with the expansion cavity, an adjusting valve is arranged on the expansion cavity, the mud suction pipe head is connected to the bottom of the expansion cavity, and the drill bit is conical and connected to the bottom of the mud suction pipe head. The high-pressure flushing mechanism and the mud suction mechanism are arranged side by side. The high-pressure flushing mechanism comprises a flushing pipe and a flushing pipe head, wherein the flushing pipe and the mud suction pipe are arranged in parallel in a spaced manner, the top of the flushing pipe is connected with a high-pressure water pump, a connecting piece is connected between the flushing pipe and the mud suction pipe, the connecting piece comprises hoops and a connecting block, the flushing pipe head is in a short pipe shape, the diameter of the flushing pipe head is smaller than that of the flushing pipe, and a jet head is arranged at the bottom of the flushing pipe head. The technical problems that according to a traditional method, the steps of processing hardened soil and sucking mud are tedious, the soil breaking capacity is low, and the dredging rate cannot be adjusted are solved.
一种水下开挖清淤装置及其施工方法，包括吸泥机构和高压冲水机构；吸泥机构包括吸泥管、扩大腔体、吸泥管管头和钻头；吸泥管上端与冲击式驱动设备相连接，吸泥管下端连有扩大腔体；扩大腔体上设有调节阀；吸泥管管头连接在扩大腔体底部；钻头呈锥形，连接在吸泥管管头底部；高压冲水机构与吸泥机构并排设置，包括冲水管和冲水管管头；冲水管与吸泥管平行间隔设置，冲水管顶部连接有高压水泵，冲水管与吸泥管之间连接有连接件；连接件包括环箍和连接块；冲水管管头呈短管状，且冲水管管头的直径小于冲水管的直径，在冲水管管头的底部设有喷射头。本发明解决了传统的方法处理板结状土壤和吸泥的步骤繁琐、土壤破除能力较低以及无法调节清淤速率的技术问题。
