Laminated assembled diversion pier structure

Abstract

The invention discloses a stacked assembly type guide pier structure. The stacked assembly type guide pier structure comprises a box type foundation, a supporting structure and a box type water retaining structure, wherein the box type foundation, the supporting structure and the box type water retaining structure are sequentially arranged from bottom to top. The box type foundation is formed by stacking a plurality of single basic foundation precast blocks in a longitudinal mode, and foundation cast-in-place holes are formed in the box type foundation. The supporting structure is formed by a plurality of box type vertical columns, and vertical column cast-in-place holes are formed in the box type vertical columns. The box type water retaining structure is formed by stacking a plurality of single basic water-retaining precast blocks in a longitudinal mode, and water retaining structure cast-in-place holes are formed in the box type water retaining structure. The water retaining structure cast-in-place holes, the vertical column cast-in-place holes and the foundation cast-in-place holes are aligned in a one-to-one corresponding mode in the vertical direction and form structure cast-in-place holes, and reinforcement cages and cast-in-place concrete structures are arranged in the structure cast-in-place holes. The stacked assembly type guide pier structure can improve the navigational flow condition of an entrance area of an approach channel, adapt to various soft foundations, lower the construction difficulty, shorten the construction period, save the materials and lower the cost.

Description

technical field [0001] The invention belongs to the technical field of water conservancy and water transportation, and in particular relates to a laminated assembled diversion pier structure. Background technique [0002] When constructing a water conservancy project on a natural river, in order to meet the needs of navigation, navigation structures such as ship locks are often installed. In the gate area where the entrance and exit of the navigable building (ie, the approach channel upstream and downstream of the ship lock) is connected with the river (or canal), the water flow is generally composed of two parts: oblique flow and return flow, and is the approach channel for ships (teams) passing through the lock. The throat of the river is at the junction of the flowing water of the river and the still water of the approach channel. The bending and deformation of the water flow produces a flow velocity gradient and forms an oblique flow. Due to the effect of oblique water ...

AI Technical Summary

Problems solved by technology

At present, the existing diversion pier structure mainly adopts solid walls and cast-in-place concrete structures, resulting in a long construction period, difficult construction and high project cost

At the same time, due to the high quality of the diversion pier structure itself, it has high requirements for the foundation, which affects its scope of use
