Description

Technical Field

[0001] The invention relates to the technical field of bank protection engineering, and in particular to a landscape platform type seawall bank protection structure and a construction method thereof. Background Art

[0002] As an important part of the connection between water and land, seawall revetments are widely used in water conservancy and water transport projects. In recent years, with the development of coastal cities, more and more projects need to build new or reinforce seawall revetments in urban coastal areas. The construction of seawall revetments in coastal cities is often restricted by the use of sea, land, front water depth, geological conditions, construction site, surrounding environment, etc.

[0003] The existing city defense seawalls facing the sea are mostly upright concrete retaining walls. Considering the treatment, wave blocking effect, embankment combination type and the impact on the marine environment, the seawall revetment structure generally adopts solid concrete retaining walls. The solid concrete retaining wall structure has good overall stability and is relatively convenient to construct, but it has a greater impact on the marine environment and involves the issue of seawall reclamation, which is not conducive to the protection of the seawall mudflat ecosystem and requires relatively high investment.

[0004] Chinese patent CN214194363U (publication date: September 14, 2021) discloses a seawall reinforcement landscape platform structure with garage function, including an old embankment top and an old concrete cantilever retaining wall facing the water surface. A raised concrete wave-breaking wall is arranged on the side of the old concrete cantilever retaining wall facing the water surface. A reinforced concrete pedestal and a plurality of first concrete columns are arranged on the raised concrete wave-breaking wall. A plurality of second concrete columns are arranged on the side of the old embankment top away from the old concrete cantilever retaining wall. A viewing platform is arranged on the first concrete column, the second concrete column and the raised concrete wave-breaking wall. The space between the viewing platform and the old embankment top forms a garage. While making reasonable use of the old revetment, the wave resistance and height of the old concrete cantilever retaining wall are increased by modifying the added raised concrete wave-breaking wall, the reinforced concrete pedestal and the plurality of first concrete columns. At the same time, the added plurality of second concrete columns, together with the plurality of first concrete columns and the raised concrete wave-breaking wall, support the viewing platform. The gap between the raised viewing platform and the old embankment top is used to form a parking garage, which greatly solves the parking problem for visitors.

[0005] Chinese patent CN107142893A (publication date: September 8, 2017) discloses a river bank protection structure, including a river channel, a slope protection is provided on one side of the river channel, a landscape platform is provided on the slope protection, and a first mortar masonry retaining wall is provided on the other side of the river channel; stone ballast is backfilled between the first mortar masonry retaining wall and the land, a concrete bottom plate is laid on the stone ballast, and the concrete bottom plate is inclined toward the side close to the land; the higher side of the concrete bottom plate is connected to the top of the first mortar masonry retaining wall, and the lower side is provided with a second mortar masonry retaining wall to form a water diversion channel. The invention provides a river bank protection structure, taking nature and harmony into consideration, embodying ecological nature in the concept of water management, avoiding channelization of the river channel and excessive management of the river channel, and realizing multiple functions.

[0006] Chinese patent CN206189340U (publication date: May 24, 2017) discloses an ecological revetment reconstruction structure of a mortar-laid block stone retaining wall, comprising: an existing revetment lower structure, the existing revetment lower structure comprising a front row of piles, a rear row of piles, a retaining wall bottom plate arranged on the top of the front row of piles and the rear row of piles and fixedly connected to the front row of piles and the rear row of piles, and a retaining wall body arranged on the retaining wall bottom plate and demolished to the design elevation; a wall body pressure top arranged on the front side edge of the top surface of the retaining wall body; a hydrophilic platform arranged on the top surface of the retaining wall body and located at the rear side of the wall body pressure top; a flood control channel arranged on the top of the river bank slope; a sloped green belt arranged on the river bank slope and located between the hydrophilic platform and the flood control channel; and a biofilm laid on the ground in front of the hydrophilic platform. The utility model has the advantages of safety and durability, beautiful ecological landscape, environmental protection and energy saving, low transformation cost, low implementation difficulty, and convenient maintenance.

[0007] Based on the above situation, it can be seen that although the existing technology has proposed the transformation of the revetment structure, its research focus is on how to carry out ecological revetment for river projects; how to carry out ecological transformation plans based on the existing revetment structure. It cannot effectively solve how to reduce the occupation of the marine environment and reduce the impact on the seawall mudflat ecosystem while ensuring the safety and reliability of the seawall revetment structure. For this reason, there is an urgent need for a new revetment structure that is easy to construct, reliable in structure, expands the water space, and has the functions of both a water landscape platform and seawall revetment.
