Embodiment Construction

[0040] The invention adopts flexible green vegetation protection surface and high polymer anti-seepage wall, so that the slope of the wharf has sufficient flexibility, and no irreparable rigid damage will occur under the action of earthquake load, and the slope adaptability is increased. The ability of soil deformation also prevents the reinforced soil from being invaded by water. At the same time, the polygonal turn-up technology of the geogrid is used to greatly reduce the slope deformation.

[0041] The present invention uses such figure 1 , 2 The shown ecological flexible geogrid reinforced wharf includes a geogrid device 5, a foundation 6, and a filling foundation 10. The geogrid device 5 is flush with the top surface of the filling foundation 10 and is constructed and installed on the foundation 6. The geogrid device 5 is formed by connecting several layers of horizontally arranged grid monomers 51. The grid monomers 51 are parallel to each other, and the upper and lower la...

Abstract

The invention belongs to the field of pier protection and earthquake resisting and provides a construction method for an ecological flexible geogrid reinforcement pier to solve the problems that most pier soil retaining facilities are of a rigid structure, and under the combined effect of seismic waves, ship loads and water pressure, breakdown phenomena that tie bars are pulled out, slip surfaces are caused inside and outside or slope faces are deformed and uplifted seriously occur easily. According to the pier, a soil body is reinforced by geogrid devices which are manufactured through the reverse wrapping technology and plant root systems, the geogrids and the plant root systems are jointly used for being occluded with soil particle padding, the stability of slopes can be greatly enhanced, and the capacity of bearing the ship loads and the water pressure of the slope faces is enhanced. The geogrid devices are distributed in an upper-lower layer graded step shape, stress is more reasonable, the structure is more stable, and deformation fatigue life is long.

Description

Technical field [0001] The invention belongs to the field of wharf protection and earthquake resistance, and specifically relates to a construction method of an ecological flexible geogrid reinforced wharf, which is a medium and small geosynthetic material ecologically reinforced wharf for hydraulic engineering. Background technique [0002] Since the major strategic concept of the Belt and Road Initiative was put forward in 2013, accelerating the construction of a number of port projects in countries along the route has become an important measure to promote the rapid development of this strategy. The construction and safety of ports and wharves are the key to the construction of the Belt and Road Initiative and are of great strategic significance. However, my country's five major port clusters along the coast are all located in the Pacific Rim seismic belt. In recent years, as seismic activity has entered a new active period, it is particularly important to enhance the seismic...
