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

Embodiment 1

[0042] After the water storage of a certain water conservancy project was completed, the upstream water level fluctuated up to 30 meters. A ship in the area near the dam leaned against the slope anchorage and adopted the bollard and protective structure of the present invention. The cable pile and protective structure have been used safely for 3 years, and there has been no problem that the erosion of the foundation at the bottom of the protective structure affects the safety of the structure.

[0043] like Figure 1 to Figure 7 As shown, a mooring bollard protective structure on a slope surface in a water level fluctuation zone includes a bollard 1, a wedge-shaped groove mooring system 2, a reinforced concrete protective structure 3, a step 4 and an anchor foundation 5; the bollard 1 is made of reinforced concrete The pouring pile 1-1, the reinforced concrete pile cap 1-2 and the bollard 1-3; the reinforced concrete protective structure 3 is set around the bollard 1, and cons...

Embodiment 2

[0061] After a water conservancy project was completed and impounded, the upstream water level fluctuated by 30 meters. There was an anchorage for ships near the dam, and three levels of bollards were installed at different elevations on the same slope. The mooring bollard and the protective structure type described in the present invention have been used safely for 3 years, and the problem that the erosion of the bottom foundation of the protective structure affects the structural safety has not occurred.

[0062] like Figure 1 to Figure 7 As shown, a bollard protective structure on a slope surface in a water level fluctuation area includes a bollard 1, a wedge-shaped groove mooring system 2, a reinforced concrete protective structure 3, a step 4 and an anchor foundation 5. The bollard 1 is composed of a reinforced concrete pouring pile 1-1, a reinforced concrete pile cap 1-2 and a bollard 1-3; The reinforced concrete lattice beam 3-2 and the reinforced concrete secondary b...

Abstract

The invention provides a protection structure and a construction method for mooring piles on slopes in water level fluctuation areas. The mooring piles include reinforced concrete pouring piles, pile caps and mooring piles. Beam and deck structure. The construction of the structure mainly includes: excavation of earth and stone on the slope surface; positioning and pouring of pile foundation; excavation of reinforced concrete lattice beam soil; anchor construction; laying of geotextile inverted filter layer; Construction; pouring of reinforced concrete face protection structure; construction of wedge-shaped groove and steps; installation of steel bollards and a series of processes.

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...
