A landscape platform type seawall revetment structure and its construction method

Abstract

This invention discloses a landscape platform-type seawall revetment structure and its construction method. The seawall revetment structure includes a slope-supporting structure, pile foundations, and a permeable floating platform. The permeable floating platform is located on the front side of the slope-supporting structure and abuts against it. By utilizing the slope-supporting structure as the seawall revetment structure and combining the floating platform and the seawall revetment, the revetment functions as both a water-based landscape platform and a seawall revetment while ensuring structural safety, thus improving the single-function nature of the seawall revetment. The construction method of the seawall revetment structure involves steps such as preliminary calculations, pile foundation construction, permeable floating platform construction, and backfilling. The slope-supporting structure and the permeable floating platform structure jointly bear the horizontal force of the seawall behind, effectively reducing land acquisition. This invention, through the landscape platform-type seawall revetment structure and its construction method, expands the water space while ensuring structural safety and reliability.

Description

Technical Field

[0001] This invention relates to the field of revetment engineering technology, specifically to a landscape platform type seawall revetment structure and its construction method. Background Technology

[0002] As an important component of the connection between land and water, seawalls and 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 or reinforce seawalls and revetments in urban coastal areas. However, the construction of seawalls and revetments in coastal cities is often limited by factors such as sea area use, land use, water depth at the front, geological conditions, construction site, and surrounding environment.

[0003] The existing coastal side of the city's seawall is mostly made of vertical concrete retaining walls. Considering the treatment, wave-blocking effect, road-embankment combination type and impact on the marine environment, the seawall revetment structure generally adopts solid concrete retaining walls. Solid concrete retaining wall structures have better overall stability and are easier to construct, but they have a greater impact on the marine environment and involve the issue of seawall reclamation, which is not conducive to the protection of the seawall tidal flat ecosystem, and the investment is relatively high.

[0004] Chinese Patent CN214194363U (publication date: September 14, 2021) discloses a seawall reinforcement and landscape platform structure that also functions as a garage. It includes an existing seawall top and an existing concrete cantilever retaining wall facing the water. A raised concrete wave-breaking wall is installed on the water-facing side of the existing concrete cantilever retaining wall. This raised concrete wave-breaking wall has a reinforced concrete foundation and several first concrete columns. Several second concrete columns are installed on the side of the existing seawall top away from the existing concrete cantilever retaining wall. A viewing platform is provided on the first concrete columns, second concrete columns, and raised concrete wave-breaking wall. The space between the viewing platform and the existing seawall top forms a garage. By making reasonable use of the existing revetment, the wave-resistance strength and height of the existing concrete cantilever retaining wall are increased through the modification and addition of the raised concrete wave-breaking wall, reinforced concrete foundation, and several first concrete columns. Simultaneously, the added several second concrete columns, together with the several 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 was used to create a parking garage, which greatly alleviated the parking difficulties for visitors.

[0005] Chinese Patent CN107142893A (publication date: September 8, 2017) discloses a riverbank protection structure, including a river channel, a slope protection on one side of the river channel, a landscape platform on the slope protection, and a first masonry retaining wall on the other side of the river channel. Stone ballast is backfilled between the first masonry retaining wall and the land, and a concrete base slab is laid on the stone ballast, with the concrete base slab inclined towards the side closer to the land. The higher side of the concrete base slab connects to the top of the first masonry retaining wall, and a second masonry retaining wall is located on the lower side, forming a water diversion channel. This invention provides a riverbank protection structure that considers nature and harmony, embodies ecological nature in water management, avoids channelization and over-treatment of the river channel, and achieves multiple functions.

[0006] Chinese Patent CN206189340U (publication date: May 24, 2017) discloses an ecological revetment renovation structure for a masonry retaining wall, comprising: an existing revetment substructure including a front row of piles, a rear row of piles, a retaining wall base plate fixed to the top of the front and rear piles, and a retaining wall body demolished to the design elevation on the retaining wall base plate; a wall capping on the front edge of the top surface of the retaining wall body; a waterfront platform on the top surface of the retaining wall body and located behind the wall capping; a flood control channel on the top of the riverbank slope; a sloping green belt on the riverbank slope between the waterfront platform and the flood control channel; and a biofilm laid on the ground in front of the waterfront platform. This utility model has advantages such as safety and durability, beautiful ecological landscape, environmental protection and energy saving, low renovation cost, low implementation difficulty, and convenient maintenance.

[0007] Based on the above, it is clear that while existing technologies have proposed modifications to revetment structures, their research focuses primarily on how to implement ecological revetment in river engineering and how to develop ecological modification schemes based on existing revetment structures. They do not effectively address how to reduce the encroachment on the marine environment and mitigate the impact on the seawall and tidal flat ecosystem while ensuring the safety and reliability of the seawall revetment structure. Therefore, there is an urgent need for a new type of revetment structure that is easy to construct, structurally reliable, expands the water space, and combines the functions of a waterscape platform and seawall revetment.

[0051] The pile foundation 1 includes a slope-adhesive structure pile foundation and a floating platform pile foundation; the slope-adhesive structure pile foundation is located below the slope-adhesive structure 7; the floating platform pile foundation is located below the crossbeam 6.

[0052] Furthermore, landscape paving 4 is laid on the permeable water platform.

[0053] Furthermore, the pile foundation 1 is a cast-in-place pile with a diameter of 75-85cm and a spacing of 2-4m between adjacent pile foundations.

[0056] Furthermore, there is an existing mud surface 2 in front of the existing retaining wall 9, and the pile foundation 1 is buried below the plane of the existing mud surface 2.

[0057] Furthermore, the longitudinal beam 3, the transverse beam 6, and the panel 5 are all made of cast-in-place reinforced concrete. The longitudinal beam 3 is 110 mm high, the transverse beam 6 is 120 mm high, and the panel 5 is 35 mm thick.

[0058] Furthermore, the distance between the slope-adhering structure 7 and the existing mud surface 2 is not less than 0.5m. The slope-adhering structure 7 adopts a cast-in-place reinforced concrete structure, including a main structure and a supporting structure. The cross-section of the main structure is "L" shaped, and the main structure is fitted into the supporting structure.

[0059] Furthermore, the main structure includes a long column and a short beam; the side of the long column is in close contact with the existing retaining wall 9, the cross-section of the long column is trapezoidal, the upper end supports the longitudinal beam 3, and the lower end is connected to the short beam; the lower end of the short beam is provided with a slope-adhesive structure pile foundation.

[0061] The technical advantages of this embodiment are as follows: A slope-supporting structure is set at the rear edge of the open-air platform on the water.

[0062] Example 3

[0063] Based on Examples 1-2, this example introduces a construction method for a landscape platform type seawall revetment structure.

[0064] Please refer to Figure 2 A construction method for a landscape platform type seawall revetment structure includes the following steps:

[0065] Step S1: Preliminary calculations. Based on current specifications, structural stability and strength calculations are performed to determine the dimensions of each component of the open-type floating platform and the dimensions of pile foundation 1.

[0066] Step S2, Pile Foundation 1 Construction: Based on the location of Pile Foundation 1, the layout area of ​​the slope-supported structure pile foundation and the water platform pile foundation is determined. The foundation pit is excavated. The site is leveled according to the current mud surface 2 elevation. The cast-in-place piles are then constructed.

[0067] Step S3: Construction of the permeable water platform and slope-adhesive structure. After the pile foundation 1 is constructed, the permeable water platform and slope-adhesive structure are cast in place on top of the pile foundation 1 according to the dimensions determined in step S1, so that the permeable water platform and slope-adhesive structure are firmly connected to the pile foundation 1.

[0068] Step S4: Backfill the excavated foundation pit with soil to complete the construction of the viewing platform type seawall revetment structure.

[0069] Furthermore, step S1 includes the following steps:

[0070] Step S1.1: Perform structural stability and strength calculations according to the current specifications for revetment, and determine the dimensions of the slope-attached structure and the pile type, pile diameter, pile spacing, and pile length of the slope-attached structure pile foundation;

[0071] Step S1.2: Perform structural stability and strength calculations according to the current specifications for open-type floating platforms, determine the dimensions of the longitudinal beams 3, transverse beams 6 and panel 5 of the floating platform, determine the spacing between the longitudinal beams 3 and transverse beams 6, and determine the pile type, pile diameter, pile spacing and pile length of the floating platform pile foundation.

[0072] The technical effect of this embodiment is that a slope-supporting structure is set at the rear edge of the open-air platform. The dimensions of the pile foundation of the slope-supporting structure and the pile foundation of the platform are calculated separately. This allows the slope-supporting structure to be better integrated with the open-air platform structure as a seawall revetment structure, so that they can jointly bear the horizontal force of the seawall behind and fully ensure the structural safety.

[0073] In summary, by setting up a slope-supporting structure along the rear edge of the open-air platform, and using the slope-supporting structure as a seawall revetment structure, while simultaneously utilizing the open-air platform structure to jointly bear the horizontal force of the seawall behind, the land acquisition is greatly reduced, the problem of using the sea area at sea is avoided, construction is convenient, the structure is reliable, and the water space is expanded. This invention is original and innovative.

[0074] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
