Water level fluctuation area slope mooring bollard protection structure and construction method thereof

Abstract

The invention provides water level variation area slope surface mooring bollard protection structure and a construction method thereof. A mooring bollard comprises a reinforced concrete cast-in-placepile, a pile cap and a mooring dolphin; and the protection structure is arranged around the mooring bollard and comprises a wedge-shaped groove, a lattice beam and a surface protection structure. Theconstruction method of the structure mainly comprises the following steps of excavating the slope earth and rockfill; positioning and pouring a pile foundation; excavating a reinforced concrete lattice beam soil body; constructing an anchor rod; laying a geotextile inverted filter layer; steel bar binding of the reinforced concrete lattice beam and constructing a drainage structure; pouring a reinforced concrete protective surface structure; constructing wedge-shaped grooves and steps; and installing the steel dolphins and the like.

Description

technical field [0001] The invention belongs to the field of water transport engineering, and more specifically relates to a bollard protective structure type and construction method for ships to berthing on slopes arranged on slopes in water level fluctuation areas. Background technique [0002] After the water conservancy project is completed to store water and form a reservoir, the combined effects of waves, water flow and groundwater in the upstream hydrodynamic fluctuation area of ​​the reservoir area will lead to serious erosion of the soil on the bank slope surface and intense reconstruction of the reservoir bank. For the mooring facilities for mooring ships on the surface of the bank slope, the soil around the structure will be washed away due to the impact of bank reconstruction. The main problems are: First, after the soil around the mooring structure is lost, the mooring structure is All or part of the soil becomes exposed outside the soil, and the stress conditio...

AI Technical Summary

Problems solved by technology

For the mooring facilities for mooring ships on the surface of the bank slope, the soil around the structure will be washed away due to the impact of bank reconstruction. The main problems are: First, after the soil around the mooring structure is lost, the mooring structure is All or part of the soil becomes exposed outside the soil, and the stress conditions of the structural design deteriorate seriously; second, when the water level rises and submerges the mooring structure, the mooring structure is higher than the surrounding terrain, and the mooring structure is a high-strength concrete structure and The steel structure can easily cause damage to the bottom of the ship and endanger the safety of the ship; third, when the soil around the mooring structure is completely eroded and exposed, it is easy to roll and fall into the river, causing a safety hazard

In the known technology at present, there is no effective solution for the above three problems
