[0022] In order for those skilled in the art to better understand the technical scheme of the utility model, the utility model will be further described in detail below with reference to the drawings.

[0023] As shown in Figures 1-4 A kind of ecological combined board pile for river permanent revetment, including the board pile 1 being provided with column frame 2 and inclined bracing plate 3, column frame 2 is fixed in the table-shaped gap between adjacent board pile 1, and fixed mounting has the shutter 21 of blocking table-shaped gap on column frame 2;

[0024] Positioning strip 22 is equidistantly arranged on shutter 21, and the end of inclined bracing plate 3 is fixedly installed with fastening end 32 abutting positioning strip 22;

[0025] The lower end of column frame 2 is provided with sharp head 20, and the lower end of inclined bracing plate 3 is fixedly installed with fixed head 31 matched with sharp head 20.

[0026] Specifically, the board pile 1 is U-shaped columnar, which is itself a prior art and will not be described here, and the protruding parts installed on the board pile 1 are the improvement points, and the protruding parts are all formed of cement material.

[0027] Further, column frame 2 and inclined bracing plate 3 are both cement column and cement plate with reinforcing steel bars poured, which can make this part of combined board pile 1 more stable and corrosion-resistant in use, and shutter 21 is located at the larger edge line position of the table shape of column frame 2, so that the shutter 21 abutting the side edge of board pile 1 has a wear and tear function, and the edge of the worn shutter 21 can make column frame 2 more fit the table-shaped gap between adjacent board piles 1, guarantee the blocking effect on water flow, and at the same time, increase the service life of column frame 2.

[0028] Further, the length of column frame 2 is greater than the length of board pile 1, so that the column frame 2 inserted into the soil of river bottom has a larger supporting area, and the upper end of column frame 2 in default state is higher than board pile 1, so that column frame 2 can cover the entire board pile 1 in the process of continuing to be inserted downward.

[0029] Further, the sharp head 20 of column frame 2 inserted into the soil of river bottom is used to increase the installation convenience effect, and the sharp head 20 is buried in the soil together with the lower end part of column frame 2, so that column frame 2 has a longer pile foundation function, increases the supporting force of column frame 2 to board pile 1, and at the same time, the multiple conical fixed heads 31 of the lower end of inclined bracing plate 3 are inserted into the soil of river bottom, so that the inclined bracing plate 3 used as inclined support is more stable.

[0030] The column frame 2 is inserted into the table-shaped gap between the adjacent sheet piles 1, and the column frame 2 plays a role of reinforcing the skeleton of the arrayed sheet piles 1, and the baffle 21 blocks the water flow at the curved river position from entering the gap, thereby effectively preventing the water flow from eroding the riverbank soil through the gap between the adjacent sheet piles 1, reducing the impact of the impact force on the vertical installation stability of the sheet piles 1, preventing the sheet piles 1 from being inclined due to the water flow, increasing the safety of the river embankment, and the inclined bracing plate 3 first contacts the water flow and guides the water flow obliquely, so that the water flow is damped by the bracing plate 3, reducing the interference of the impact force on the column frame 2, and the fastening end 32 is obliquely fixed to the positioning strip 22, so that the bracing plate 3 forms a triangular support for the column frame 2, further strengthening the reinforcing effect of the column frame 2 on the sheet piles 1, and making the vertical direction of the sheet piles 1 more stable.

[0031] As a further embodiment of the utility model, the side of the column frame 2 is fixedly provided with symmetrically arranged auxiliary inclined convexities 24, and the side of the sheet pile 1 is fixedly provided with auxiliary contact convexities 12 which slide against the auxiliary inclined convexities 24.

[0032] Specifically, the auxiliary inclined convexities 24 are located on the tapered side of the table, and the cross section of the auxiliary inclined convexity 24 is an obtuse triangle, and the arc top of the auxiliary contact convexity 12 with a semicircular cross section is used to abut against the tapered side, so that the column frame 2 cannot be inclined during the abutting process and continues to move downward.

[0033] When the side of the sheet pile 1 is inclined, the auxiliary contact convexity 12 in the inclined state extrudes the auxiliary inclined convexity 24, and the column frame 2 continues to be inserted into the river bottom soil, and the column frame 2 has resistance during the insertion process, so that the auxiliary inclined convexity 24 offsets the inclination force of the auxiliary contact convexity 12, and thus the sheet pile 1 is not easy to be inclined, and if the inclination force causes the column frame 2 to continue to be inserted downward, the column frame 2 can still play a role of skeleton support for the sheet pile 1, and the support effect is increased with the increase of the depth.

[0034] As a further embodiment of the utility model, the end surface of the column frame 2 is fixedly provided with a main inclined convexity 23, the end of the sheet pile 1 is fixedly provided with a main contact convexity 11 which is in contact with the main inclined convexity 23, and the auxiliary inclined convexity 24 in sliding cooperation increases the distance between the main inclined convexity 23 and the main contact convexity 11.

[0035] Specifically, the length of the main inclined convexity 23 is greater than the length of the auxiliary inclined convexity 24, and the sliding length of the main contact convexity 11 abutting against the main inclined convexity 23 in the default state is equal to the sliding length of the auxiliary inclined convexity 24 and the auxiliary contact convexity 12.

[0036] The main inclined convex 23 plays the same role of offsetting the deflection force as the auxiliary inclined convex 24, so that the sheet pile 1 can be offset when subjected to multiple deflection forces in three different directions (one of the faces of the sheet pile 1 transmits the force to the riverbank soil to offset), and the column frame 2 driven by the auxiliary inclined convex 24 moves to pull away the contact distance between the main inclined convex 23 and the main contact convex 11, that is, the main contact convex 11 moves upward relative to the main inclined convex 23 and keeps in contact (the inclined support plate 3 applies a support force to the column frame 2), so that the main inclined convex 23 and the main contact convex 11 have a larger working distance, and the support capacity and the deflection force offsetting capacity of the column frame 2 to the sheet pile 1 are improved.

[0037] As another embodiment further provided by the utility model, a clamping groove 13 is arranged at the end of the adjacent sheet pile 1 and is embedded with the main inclined convex 23.

[0038] Specifically, the clamping groove 13 is located below the main contact convex 11.

[0039] After the auxiliary inclined convex 24 and the main inclined convex 23 consume the existing offsetting capacity, the main inclined convex 23 used for finishing moves downward until it is embedded in the clamping groove 13 to be fixed, at this time, the column frame 2 is permanently fixed with the sheet pile 1 under the oblique support of the inclined support plate 3, and the column frame 2 is already in the deepest insertion position, so that the protection effect of the sheet pile 1 is maximized, and the sheet pile 1 has the highest stability at the insertion depth.

[0040] As still another embodiment further provided by the utility model, the main inclined convex 23 in sliding cooperation adjusts the included angle between the inclined support plate 3 and the column frame 2.

[0041] Specifically, the plurality of positioning strips 22 can change the fixed position between the inclined support plate 3 in advance, so that the actual assembly application range of the inclined support plate 3 is wider.

[0042] The column frame 2 deeply inserted downward is provided with a support force obliquely upward by the inclined support plate 3, so that the column frame 2 is difficult to move downward, that is, the deflection force is subjected to stronger offsetting processing, but when the column frame 2 moves downward, the inclined support plate 3 is driven obliquely downward in the process of offsetting the deflection force, so that the fixed end 32 kept in fixed position forms a rotation point between the positioning strip 22, the included angle between the inclined support plate 3 and the column frame 2 is increased, and the gravity center of the triangular support is lowered, so that the support position after the gravity center is lowered is more stable, and the obtained support effect is better.

[0043] Working principle: by inserting the column frame 2 into the platform-shaped gap installed between adjacent sheet piles 1, the column frame 2 plays a role of reinforcing the skeleton of the arrayed sheet piles 1, and the blocking of the platform-shaped gap by the baffle 21 prevents the water flow at the curved river position from entering the gap, effectively avoiding the water flow from eroding the riverbank soil through the gap between adjacent sheet piles 1, so that the sheet piles 1 are not easily deflected by water impact during work, and the obliquely arranged inclined support plate 3 first contacts the water impact and performs oblique drainage, so the water flow can be broken by the inclined support plate 3, reducing the interference of the impact force on the column frame 2, and the fastening end 32 is obliquely upwardly fixed to the positioning strip 22, so that the inclined support plate 3 forms a triangular support to the column frame 2, further strengthening the reinforcing effect of the column frame 2 on the sheet piles 1, and when the side of the sheet piles 1 is deflected, the auxiliary inclined convex 24 is pressed by the auxiliary convex 12 in the deflected state, and the column frame 2 continues to be inserted into the river bottom soil, and the column frame 2 has resistance during the insertion process, so that the auxiliary inclined convex 24 offsets the deflection force of the auxiliary convex 12, so that the sheet piles 1 are not easily deflected, and if the deflection force causes the column frame 2 to continue to insert downward, the column frame 2 can still play a role of skeleton support to the sheet piles 1, and the support effect is increased with the increase of the depth.

[0044] The above only describes some exemplary embodiments of the present application by way of illustration, without doubt, for ordinary skilled in the art, without departing from the spirit and scope of the present application, the described embodiments can be modified in various ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the present application.
