U-shaped plate combined assembled diversion pier structure

Abstract

The invention discloses a U-shaped plate combination assembling type flow guide pier structure which comprises a prefabricated bottom plate fixed to a river bed. The upstream end and the downstream end of the prefabricated bottom plate are each fixedly provided with a prefabricated load bearing wall. A plurality of evenly-distributed prefabricated flow guide walls are arranged between the two prefabricated load bearing walls. Flow passing holes are formed between the prefabricated load bearing walls and the corresponding adjacent prefabricated flow guide walls and between every two adjacent prefabricated flow guide walls respectively. The flow cross section of the river bed end of each flow passing hole is smaller than the flow cross section of the approach channel end of the flow passing hole. Each middle main wall is provided with an inverse prefabricated U-shaped plate in a buckled mode. A connecting gap is formed between every two adjacent prefabricated U-shaped plates. A water stop asphalt bonding layer is formed in each connecting gap. Grooves are formed in the inverse tops of the prefabricated U-shaped plates. Ecological layers are arranged in the grooves. The U-shaped plate combination assembling type flow guide pier structure can improve navigation flow conditions of an entrance area of an approach channel; construction is convenient, and the engineering cost is low; maintenance and repair are convenient.

Description

technical field [0001] The invention belongs to the technical field of water conservancy and water transportation, and in particular relates to a U-shaped plate combined assembly type diversion pier structure. Background technique [0002] When building a water conservancy project on a natural river, in order to meet the needs of navigation, navigable structures such as ship locks are often set up. Diagonal water flow and return flow are two parts. It is the throat of ships (teams) entering and exiting the approach channel. It is located at the junction of the moving water of the river and the still water of the approach channel. Due to the effect of oblique water flow, backflow and separate small vortex are generated. The cross flow and backflow will cause the sailing ship (team) to drift and twist. In severe cases, it will lose control, resulting in accidents and affecting navigation. [0003] In order to ensure the safe and smooth navigation of the ship (team), the water...

AI Technical Summary

Problems solved by technology

The existing diversion pier structure mainly adopts solid walls and cast-in-place concrete structures, resulting in a long construction period and difficult construction. At the same time, it is not easy to repair when the diversion pier is damaged by accidental collision with the hull, thus affecting its use function
