[0025] In the present invention, for the sake of clear description, the following explanation is made: the observer faces the attached Figure 1 The above description is only for the convenience of describing the utility model clearly, and does not indicate or imply that the structure or parts referred to must have a specific orientation or be constructed in a specific orientation, so it cannot be understood as a limitation of the utility model.

[0026] Please combine Figure 1 and Figure 2, A retaining pile 1 with a weighing plate is applied in the fields of water conservancy and slope engineering for anti-sliding, soil retaining, and support. The retaining pile 1 includes a pile body 11, a web 12, and a weighing plate 13. The upper half of the pile body 11 is a retaining part for resisting the slope to prevent landslides, and the lower half of the pile body 11 is an anchoring part for embedding into the soil for anchoring. The cross-section of the pile body 11 can be rectangular, D-shaped, trapezoidal, or other geometric shapes, and the ratio of the horizontal net distance to the vertical net distance of the cross-section of the pile body 11 is greater than 2; the web 12 is fixed at the center position on the back of the pile body 11 and is integrally formed with the pile body 11. The top of the web 12 is lower than the top of the pile body 11. The web 12 covers the junction of the retaining part and the anchoring part of the pile body 11, and the web 12 is used to enhance the bending and shear resistance of the pile body 11 under the action of soil pressure. The cross-section of the web 12 is rectangular, trapezoidal, or other polygons; the weighing plate 13 is connected to the web 12, the weighing plate 13 is perpendicular to the web 12, and at least one layer of the weighing plate 13 is provided longitudinally along the web 12. The cross-section of the weighing plate 13 is rectangular or trapezoidal. The weighing plate 13 is inserted into the soil, and the weighing plate 13 is used to bear the weight of the soil. The weighing plate 13 moves the center of gravity of the pile body 11 backward to resist the force generated by the soil on the pile body 11, thereby improving the stability and anti-overturning ability of the retaining pile 1.

[0027] Specifically, the distance from the top of the web 12 to the top of the pile body 11 is H, where 0 < H < 100 cm, which is convenient for installing a hoop at the top of the pile body 11; the lower end of the web 12 follows the anchoring part of the pile body into the soil. The web 12 can be set in multiple sections according to actual needs, and the total length of the web 12 is greater than the length of the retaining part of the pile body 11 and less than the total length of the pile body 11.

[0028] Furthermore, when the retaining pile 1 is in use, the connection part between the retaining part and the anchoring part is subjected to the greatest pressure and is prone to breakage. The web 12 covers the connection part, which can enhance the bending and shear resistance of the pile body 11 under the action of soil pressure.

[0029] Specifically, the weighing plate 13 can be arranged on both sides of the web 12 or at the end of the web 12. The weighing plate 13 can be integrally formed with the web 12 or formed separately, and then the weighing plate 13 is fixed to the web 12 according to actual construction requirements.

[0030] Furthermore, according to specific construction requirements, holes can be drilled at the top of the web 12 and the end of the counterweight plate 13, and the two ends of the cable can pass through the top of the web 12 and the end of the counterweight plate 13 respectively. The supporting pile 1 can be self-anchored through the cable to improve the stability and anti-overturning ability of the supporting pile 1; holes can also be opened on the counterweight plate 13 to facilitate water permeability.

[0031] Specifically, a steel bar skeleton formed by roll welding is arranged inside the pile body 11, and the support pile 1 is connected in a T-shape to reduce the power consumption of manual binding of special-shaped cross-sections.

[0032] Please combine Figure 3 and Figure 4 In order to facilitate the connection of adjacent support piles 1, the two sides of the support pile 1 can be respectively provided with a first connection end 14 and a second connection end 15, the first connection end 14 and the second connection end 15 fit together, the first connection end 14 is a convex tenon, the second connection end 15 is a concave tenon, the first connection end 14 can be an arcuate convex tenon, the second connection end 15 can be an arcuate concave tenon, and the connection edge can be a beveled edge, so as to facilitate the connection by rotating a certain angle according to actual construction requirements. The shapes of the first connection end 14 and the second connection end 15 can also be trapezoidal or overlapped.

[0033] Specifically, the top ends of the first connection end 14 and the second connection end 15 are flush with or lower than the top end of the pile body 11. The top of the pile body 11 may not be provided with the first connection end 14 and the second connection end 15, so as to facilitate the installation of a clamp at the top end of the pile body 11. If the first connection end 14 and the second connection end 14 extend to the top end of the pile body 11, the shape of the clamp is relatively complicated and difficult to install and tighten.

[0034] Furthermore, the distance between the top of the first connection end 14 and the top of the second connection end 15 and the top of the pile body 11 is less than 5 cm.

[0035] Furthermore, there is a gap between the top ends of the adjacent pile bodies 11 , and a cap beam may be installed at the top ends of the pile bodies 11 .

[0036] Please combine Figure 2 and Figure 3 The support pile 1 may also be provided with a boss 16, which is transversely arranged on the front of the pile body 11, and a plurality of bosses 16 are evenly arranged on the front of the pile body 11. No boss 16 is arranged on the top of the pile body 11, and a plurality of bosses 16 form a ladder. When the support pile 1 is installed on the river bank, the boss 16 can be used as a step for people who fall into the water to climb. The cross section of the boss 16 can be a right-angled trapezoid, or other shapes that are convenient for climbing.

[0037] Furthermore, the angle between the boss 16 and the pile body 11 can be set to be greater than 0° and less than 100°, so as to facilitate climbing by people who fall into the water.

[0038] The supporting pile 1 may also be provided with a plurality of water-permeable holes 17, which are provided on the pile body 1 and located on both sides of the web 12. The water-permeable holes 17 are inclined through holes for draining the accumulated water in the soil and reducing the adverse effect of the water pressure on one side of the soil on the supporting pile 1.

[0039] like Figure 5 As shown, the support pile 1 can be used alone or as a component. The utility model also provides a support pile component, which includes a support pile 1 and a retaining wall block 2. The adjacent support piles 1 are connected by the first connecting end 14 and the second connecting end 15. The counterweight plate 13 can be installed at the end of the web 12 or on both sides of the web 12. The counterweight plate 13 can be used in conjunction with each support pile 1, or it can be larger in size and shared by multiple support piles 1. The retaining wall block 2 is installed on the counterweight plate 13 at the top. The retaining wall block 2 can be a rectangular retaining wall block or a "J"-shaped retaining wall block. Usually, a temporary cofferdam needs to be built when the retaining wall block 2 is installed, and the temporary cofferdam needs to be removed after the installation is completed. The counterweight plate 13 can be used as the base of the retaining wall block 2, and there is no need to build a temporary cofferdam, saving material, manpower and time. When the pressure to be withstood in actual construction is relatively small, the retaining wall block 2 may also be directly installed on the top of the web 12 without the need to provide the counterweight plate 13 .

[0040] In summary, the utility model improves the bending and shearing resistance of the supporting piles under the action of soil pressure; improves the stability and anti-overturning ability of the supporting piles; combines the advantages of the supporting piles and retaining wall blocks, and the retaining wall blocks do not need to build temporary cofferdams during construction, saving manpower and material resources and improving work efficiency.

[0041] Therefore, the utility model effectively overcomes various shortcomings in the prior art and has a high industrial utilization value. The above embodiments are only illustrative of the principles and effects of the utility model, and are not used to limit the utility model. Anyone familiar with this technology can modify or change the above embodiments without violating the spirit and scope of the utility model. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed by the utility model should still be covered by the claims of the utility model.
