Description

Technical Field

[0001] This invention relates to a prefabricated ecological guide embankment structure and its construction method. Background Technology

[0002] Guide dikes can guide and change the direction of water flow, reduce siltation, and maintain channel depth. Guide dikes are often constructed using riprap sloping dikes or geotextile-filled bag-core sloping dikes. Sloping dikes are simple in structure, easy to construct, and have high overall stability, suitable for various foundations, and can utilize locally sourced materials. However, they consume a large amount of material (almost proportional to the square of the water depth), and are generally suitable for shallower waters with abundant stone resources. When the surface soil is poor, foundation reinforcement measures such as plastic drainage boards are often required. In estuaries with large waves and open water surfaces, other structures are also used, such as the reinforced concrete semi-circular structure and hollow tetrahedral structure of the Yangtze River estuary guide dikes. Due to environmental factors such as wave impact and water erosion, guide dike structures are prone to damage to their facing or bottom protection structures, requiring frequent maintenance. Many damaged guide dikes cannot be repaired promptly, and some structures present difficulties in maintenance.

[0003] In recent years, the requirements for ecological and environmental protection have become increasingly stringent. In addition to their functions of diversion, silt reduction and sand blocking, the impact of existing dike structures on environmental protection and ecology also needs to be considered. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects of the prior art and provide a prefabricated ecological guide embankment structure and its construction method, which can reduce on-site construction, facilitate later maintenance and replacement, and increase ecological functions.

[0005] One technical solution to achieve the purpose of this invention is: a prefabricated ecological guide dike structure, which is assembled from multiple guide dike units, each guide dike unit including an upper structure and a foundation structure; The upper structure includes a curved panel and two curtain panels; wherein the curved panel is a precast reinforced concrete structure in the shape of a round arch, and each end of the curved panel extends horizontally inward with a support foot; the top surfaces of the two curtain panels are connected one-to-one to the bottom surface of the outer edge of the two support feet of the curved panel. The basic structure includes a mud-insertion structure and two vertical slabs. The mud-insertion structure is a precast reinforced concrete structure inserted into the underwater mud surface. The two vertical slabs are precast reinforced concrete structures and are longitudinally fixed at a horizontal interval in the middle of the top surface of the mud-insertion structure. The distance between the outer sides of the two vertical slabs matches the distance between the inner sides of the support feet of the upper structure. Each of the outer sides of the middle height of the two vertical slabs extends outward with a corbel. The distance between the outer sides of the two corbels matches the distance between the inner sides of the two curtain panels of the upper structure, so that the top surfaces of the corbels of the two vertical slabs are supported one-to-one on the bottom surface of the two support feet of the curved panel of the upper structure, and an ecological channel is formed between the lower outer sides of the two vertical slabs and the inner sides of the corresponding curtain panels.

[0006] The aforementioned prefabricated ecological guide dike structure comprises several reinforced concrete grating panels or a single piece of flexible fabric for each side curtain panel. When the curtain panel is made of reinforced concrete grating panels, the opening size of the reinforced concrete grating panels is sufficient for the passage of aquatic organisms, and the height of the reinforced concrete grating panels is adapted to the distance between the bottom surface of the upright plate and the top surface of the corbel. Several reinforced concrete grating panels are connected longitudinally by reinforced concrete connecting rods. When the curtain panel is made of flexible fabric, the height of the flexible fabric is greater than the distance between the bottom surface of the upright plate and the top surface of the corbel, and the flexible fabric... The fabric includes an upper suspended section and a lower flat section. The height of the suspended section is adapted to the distance between the bottom surface of the upright plate and the top surface of the corbel. The suspended section has intermittent perforations, the size of which allows aquatic organisms to swim through. Flexible material connecting rods are longitudinally installed in the perforations. An ecological channel is formed between the inner side of the suspended section and the lower outer side of the corresponding upright plate. The non-perforated area of ​​the suspended section and the flat section are both provided with a sandwich layer, in which aquatic plants are cultivated or sand is filled. Embedded parts are set on the bottom surface of the outer edge of the support foot of the curved panel, so that the top of the flexible curtain is connected to the embedded parts through a pressure plate.

[0007] In the aforementioned prefabricated ecological guide embankment structure, the mud-entry structure is a negative pressure tank with a rounded waist shape in plan.

[0008] The aforementioned prefabricated ecological guide embankment structure includes, in its upper structure, multiple upper ribs that are longitudinally spaced and fixed to the inner surface of the curved panel and are made of precast reinforced concrete; and in its foundation structure, multiple lower ribs that are longitudinally spaced and correspond one-to-one with the upper ribs, and are located between the inner sides of the two vertical panels and are made of precast reinforced concrete.

[0009] In the aforementioned prefabricated ecological guide embankment structure, the support feet and inner surfaces of the curved panel are corrugated; the foundation structure also includes a pad between the top surface of the corrugated leg and the outer surface of the upright plate above the corrugated leg, the outer surface of which has a corrugated structure.

[0010] In the aforementioned prefabricated ecological guide embankment structure, the pads are arranged continuously or spaced apart longitudinally, and the pads are made of a micro-elastic material.

[0011] Another technical solution to achieve the purpose of the present invention is: a construction method for a prefabricated ecological guide embankment, based on the prefabricated ecological guide embankment structure of the present invention, the construction method includes the following process: construction preparation, transportation and installation of the foundation structure and transportation and installation of the superstructure; The construction preparation process includes the following steps: S1. Determine the prefabrication site and prepare materials, construction equipment and personnel; S2. Precast superstructure and foundation structure; the superstructure and foundation structure are both reinforced concrete structures, and the precasting sequence is: reinforcement binding → formwork installation → concrete pouring → formwork removal → curing. When carrying out the basic structure transportation and installation process, the basic structure is transported to the construction site by transport ships, and then a crane ship is used in conjunction with measurement and positioning equipment to sink and install the basic structure until the mud-entry structure under the basic structure sinks into the soil layer. When carrying out the superstructure transportation and installation process, the superstructure is first transported to the construction site by a transport ship, and then a crane ship is used in conjunction with measurement and positioning equipment to install the superstructure until the superstructure is fastened to the top surface of the corbels of the two vertical plates of the foundation structure. The transport barge is equipped with a support frame on its deck. This support frame is a steel structure and includes a row of left-side vertical members, a row of right-side vertical members, a row of lower horizontal members, a row of upper horizontal members, lower left and right longitudinal members, upper left and right longitudinal members, a row of left-side support members, and a row of right-side support members. The row of left-side vertical members and the row of right-side vertical members are arranged opposite each other, and the distance between the outer surface of the row of left-side vertical members and the outer surface of the row of right-side vertical members matches the distance between the inner surfaces of the two end support feet on the curved panel of the superstructure. A row of lower horizontal members connects the lower inner surface of the row of left-side vertical members and the lower inner surface of the row of right-side vertical members. A row of upper horizontal members connects the upper inner surface of the row of left-side vertical members. Between the side and the upper inner side of a row of right vertical bars; the lower left vertical bar connects to the lower part of a row of left vertical bars; the lower right vertical bar connects to the lower part of a row of right vertical bars; the upper left vertical bar connects to the upper part of a row of left vertical bars; the upper right vertical bar connects to the upper part of a row of right vertical bars; a row of left support bars are vertically connected to the upper outer surface of a row of left vertical bars, and the vertical distance between the top surface of the row of left support bars and the bottom surface of the row of left vertical bars is greater than the height of the curtain panel of the upper structure; a row of right support bars are vertically connected to the upper outer surface of a row of right vertical bars at the same height as the row of left support bars. The two ends of the curved panel of the upper structure are placed on the top surfaces of the left and right support rods of the support frame, respectively. If the curtain panel is made of reinforced concrete grating, the two curtain panels are suspended on the outside of the left and right support rods, respectively. If the curtain panel is made of flexible fabric, during the transportation of the upper structure, the two curtain panels are flipped up to the top of the upper structure and temporarily fixed thereon. After the two ends of the curved panel of the upper structure are placed on the top surfaces of the corbels of the two vertical panels of the foundation structure, the two curtain panels are flipped down and the flat sections of the two curtain panels are spread outwards to the outside of the corresponding suspended sections on the top surface of the mud-embedded structure of the foundation structure.

[0012] In the above-mentioned construction method of prefabricated ecological guide embankment, stiffening plates are respectively installed between the bottom surface of a row of left-side support rods and the upper outer side of a row of left-side vertical rods, and between the bottom surface of a row of right-side support rods and the upper outer side of a row of right-side vertical rods.

[0013] The prefabricated ecological guide embankment structure and its construction method of the present invention have the following characteristics: 1) The structure adopts two main modules: the superstructure and the foundation structure, which reduces on-site construction, facilitates later maintenance and replacement, and improves the convenience of structural repair. 2) By setting up an ecological passage between the two vertical slabs of the foundation structure and the two curtain slabs of the superstructure, the ecological function of the guide embankment is increased.
