Power pipe network for clearing deposits under dock

Abstract

The invention discloses a power pipe network for clearing deposits under a dock. The dock comprises a dock platform and foundation piles arranged to form a plurality of bent frames; the power pipe network comprises a support extending from a rear edge of the dock platform, and a header pipe arranged on the support; a plurality of paralleled branch pipes are connected onto the header pipe, and arranged along the foundation piles on rear parts of the bent frames; horizontal pipes are connected to tail ends of the branch pipes, are paved on a mud surface along the bent frames, and are connected through longitudinal pipes; the power pipe network also comprises a power control system and an injection system; the power control system is connected with the header pipe; and the injection system is arranged on the horizontal pipes or the longitudinal pipes. The power pipe network starts an air (water) pump at set intervals according to bank slope deposit degree, and deposited slits are washed away through air (water) flow and are taken away through a water flow function, so that the function of clearing the deposits is realized.

Description

technical field [0001] The invention belongs to port engineering, and in particular relates to a power pipe network for removing silt under a wharf. Background technique [0002] The removal of sediment deposits under the high-piled wharf is an important part of the daily maintenance of the high-piled wharf in waters with high sediment content. The survey data show that the ports in the lower reaches of the Yangtze River and the coastal areas of the Yangtze River Estuary and the ports in the Yongjiang Estuary area have silted up behind and below the full hall and short trestle piers, and some of the piers were not dredged in time, causing the silt to push the wharf and cause a large displacement Even the phenomenon of broken piles brings hidden dangers to the safe use of wharf structures. [0003] Generally, there are two types of desilting work under the wharf: 1) allowing the silt accumulated under the wharf to accumulate in the waters at the front of the wharf, and clear...

AI Technical Summary

Problems solved by technology

[0010] 2) Incomplete dredging

Usually, it is easy to meet the design requirements between the bent frames, and the pile body and its surroundings are caused by the phenomenon that the mud surface is too high due to the silt bonding to the pile body.

[0011] 3) Heavy workload on water

The dredging work needs to be equipped with water equipment and ship equipment, the work process is interlocking, and the shifting operation frequently mobilizes construction machinery and tools

[0012] 4) Low efficiency

After the compacted silt is stirred, it becomes mud, and the volume increases by more than 3 times, resulting in doubled construction workload and reduced efficiency

[0013] 5) No energy saving

This method is suitable for water areas where water can flow naturally, so the jet pipe network is laid according to the state of the waterway but cannot be used for port terminals
