Description

Technical Field

[0001] The invention relates to the technical field of plastic-steel sheet piles, and in particular to an ecological plastic-steel sheet pile that can "breathe". Background Art

[0002] Plastic steel sheet piles are a new type of water conservancy material that can be used for river bank protection, waterway bank protection, hydraulic construction anti-seepage and other projects. Plastic steel sheet piles are high molecular resin polymers, and have good performance in corrosion resistance, UV resistance, corrosion resistance, weather resistance, oxidation resistance, ant resistance, frost resistance and high temperature resistance. Plastic steel sheet piles have strong tensile strength, compressive strength, bending strength, and strong impact resistance. The material composition of plastic steel sheet piles is stable, does not contain heavy metals and various plasticizers, is not affected by climate and water quality, has anti-pollution properties, and does not contain toxic and harmful substances. The construction is convenient and fast, takes up little space, and has no maintenance costs in the later stage. It provides an economical and environmentally more optimized option for river and water environment management.

[0003] Traditional plastic steel sheet piles do not have water-permeable and air-permeable holes, and have good anti-seepage properties, but at the same time they also block the connectivity between groundwater and surface water, and block the replenishment and drainage relationship between groundwater and surface water. Existing plastic steel sheet piles with circular permeable holes can open up the connection between groundwater and surface water, but the existing circular permeable hole structure is set with 50-80mm diameter drainage holes in accordance with the "Technical Specifications for Plastic Steel Sheet Pile Retaining Walls for Water Conservancy Projects" (T / CWEA 18-2023). First, it will reduce the tensile, compressive, and bending strengths of plastic steel sheet piles, and second, it will increase the cost and construction difficulty of reverse osmosis filtration facilities; third, when the reverse osmosis filtration facilities fail, it will lead to pipe bursts, causing soil erosion and seriously affecting the safety of the river.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Combine the following Figures 1 to 6 , describing an embodiment of the present invention.

[0032] The present invention provides an ecological plastic-steel sheet pile that "can breathe", comprising: a main body 1, a plurality of holes 2 are opened on the main body 1, the front side of the main body 1 is used to face the surface water body, a plurality of raised structures 3 are fixedly arranged on the front side of the main body 1, the number of the raised structures 3 and the number of the holes 2 are the same, the raised structures 3 are in a concave shell shape, one raised structure 3 buckles one hole 2, the bottom edge and two side edges of the raised structure 3 are fixedly connected to the main body 1, that is, the part where the raised structure 3 is fixedly connected to the main body 1 is a continuous connecting surface, which is roughly "U"-shaped, and each raised structure 3 is surrounded by a cavity with a top opening or a bottom opening on the front side of the main body 1.

[0033] In the solution provided by the present invention, the structural strength of the opening of the main body 1 is enhanced by the protruding structure 3, and the direction of groundwater seepage is changed by forming a cavity with a top opening or a bottom opening, thereby preventing soil erosion. Therefore, the ecological plastic steel sheet pile structure provided by the present invention can not only connect groundwater with surface water, but also improve the tensile, compressive and bending strength of the plastic steel sheet pile.

[0034] Therefore, the embodiments of the present invention have the following four technical effects:

[0035] 1. The present invention enhances the tensile, compressive and bending strengths of the plastic-steel sheet piles, while ensuring the water-permeability and air-permeability of the plastic-steel sheet piles.

[0036] 2. The "breathing" ecological plastic steel sheet pile provided by the present invention can use no reverse osmosis filtration material or use less reverse osmosis filtration material according to the situation, thereby reducing costs and construction difficulty.

[0037] 3. The raised structure 3 can hinder the movement of sediment on both sides, thereby effectively preventing or reducing the phenomenon of soil erosion caused by pipe bursts.

[0038] 4. Due to the setting of the raised structure 3, under the premise of ensuring the strength of the plastic-steel sheet pile, a larger hole 2 can be opened to increase the groundwater permeability area, so that the groundwater can penetrate the plastic-steel sheet pile more quickly.

[0039] In some embodiments, the main body 1 and the protruding structure 3 are integrally formed by a stamping process.

[0040] In the embodiment of the present invention, the one-piece "breathing" ecological plastic steel sheet pile structure has better strength.

[0041] In some embodiments, the cavity is flat, that is, the thickness of the cavity (the dimension along the direction perpendicular to the surface of the main body 1) is smaller than the width of the cavity, the length direction of the cavity is parallel to the width direction of the main body 1, and the width direction of the cavity is parallel to the height direction of the main body 1 in use.

[0042] The flat cavity provided in this embodiment has a better effect of hindering the migration of sediment, and therefore has a good effect of preventing pipe bursts.

[0043] In some embodiments, the plurality of holes 2 are arranged in a rectangular array, that is, the plurality of holes 2 form a plurality of rows of holes 2 and a plurality of columns of holes 2 in a rectangular array.

[0044] In some embodiments, the top of each protruding structure 3 extends to no lower than the top edge of the hole 2 , or in other words, the projection of the protruding structure 3 completely covers the hole 2 .

[0045] In some embodiments, a plurality of reinforcing ribs 8 extending along the height direction are disposed on the main body 1 , and the plurality of reinforcing ribs 8 are disposed in parallel and at intervals.

[0046] The reinforcing ribs 8 in this embodiment can enhance the structural strength of the main body 1 . In addition, the hole 2 is disposed between the two reinforcing ribs 8 , and the opening position of the hole 2 avoids the reinforcing ribs 8 , thereby reducing the influence of the opening on the structure of the main body 1 .

[0047] In some embodiments, the main body 1 is an M-shaped plastic-steel sheet pile component, an F-shaped plastic-steel sheet pile component, or a Z-shaped plastic-steel sheet pile component.

[0048] This embodiment provides a variety of configurations of the main body 1 , and it is understandable that they are not limited to the above configurations.

Of course, the M-type plastic steel sheet pile component can also be a component more similar to "M", which is not shown in this embodiment. The F-type plastic steel sheet pile component or the Z-type plastic steel sheet pile component is respectively Figure 4 and Figure 5 The components shown in .

[0050] When the main body 1 is an M-shaped plastic steel sheet pile component, in some embodiments, a groove-shaped recess is constructed on the main body 1, and the groove-shaped recess extends from the top of the main body 1 to the bottom of the main body 1. The groove-shaped recess includes a bottom plate and two side plates, and one end of the two side plates is respectively connected to both sides of the bottom plate in the width direction. The hole 2 is opened on the bottom plate, and the protruding structure 3 is fixedly arranged on the front side of the bottom plate.

[0051] In some embodiments, the two side edges of the main body 1 in the length direction are respectively constructed with matching C-shaped lock buckles 6 and T-shaped lock buckles 5.

[0052] In this embodiment, the T-shaped lock buckle 5 on one main body 1 is used to be inserted into the C-shaped lock buckle 6 on another main body 1 to achieve the connection between two adjacent main bodies 1.

[0053] In some embodiments, the hole 2 is a rectangular hole, and the long side of the hole 2 is parallel to the width direction of the main body 1 .

[0054] In some embodiments, the raised structure 3 includes a flat plate portion and three curved plate portions. The flat plate portion is rectangular. The flat plate portion is parallel to the main body 1 and has a gap. One side of the three curved plate portions is respectively connected to the three edges of the flat plate portion, and the other sides of the three curved plate portions are fixedly connected to the front side of the main body 1. The three curved plate portions are connected in sequence.

[0055] In some embodiments, the length of the hole 2 and the length of the cavity, the height of the hole 2 and the height of the cavity can be adjusted according to the actual situation of soil particle gradation.

[0056] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
