It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0025] Reference Figures 1 to 3 A slope support structure shown includes a double-row pile unit 10, a retaining wall 30, a buttress retaining wall 40 and a supporting rib 50. The double-row pile unit 10 is inserted on the bottom of the slope protection 20; the retaining wall 30 is arranged on the outward side of the upper part of the double-row pile unit 10; the buttress retaining wall 40 is arranged on the inner side of the top of the double-row pile unit 10 and the top is flush with the backfill ground; the supporting rib 50 is arranged on the top of the double-row pile unit 10 and is used to support the outward side of the buttress retaining wall 40.
[0026] The double-row pile units 10 are conventional bored concrete piles. The portion of the double-row pile units 10 exposed above the ground is at least greater than half the height of the slope protection 20. In this application, the portion of the double-row pile units 10 exposed above the ground must reach at least 60% of the height of the slope protection 20. This design can ensure the support capacity of the slope protection 20. The bottom of the retaining wall 30 is inserted below the ground at the bottom of the slope protection 20, and the length of the retaining wall 30 below the ground is cast according to the actual support requirements. It should be noted that a plurality of double-row pile units 10 are provided, which are sequentially arranged on the sides of the slope protection 20 for support. Connecting structures, such as connecting beams, are provided between them to connect all double-row pile units 10 into a whole, thereby improving the overall strength and support capacity.
[0027] This slope support structure incorporates a buttress retaining wall 40, designed on the basis of the double-row pile units 10. As an upper extension of the double-row pile units 10, the buttress retaining wall 40 can replace the double-row pile units 10, effectively shortening the construction period, reducing the scale and difficulty of construction, and thus lowering overall construction costs. The bottom of the buttress retaining wall 40 is inserted into the top of the double-row pile units 10, enhancing the connection between the two. Furthermore, the buttress ribs 50 provide support, increasing overall strength.
[0028] See also Figure 1 and Figure 2In one embodiment of the present application, the double-row pile unit 10 comprises a front row of piles 11 and a rear row of piles 12, which are arranged in parallel along the length direction of the slope protection 20, and the top of the front row of piles 11 and the rear row of piles 12 are connected by at least one connecting beam 13, and the retaining wall 30 is arranged between two adjacent front row of piles 11; the front row of piles 11 and the rear row of piles 12 of two adjacent double-row pile units 10 are connected by a connecting beam 14 respectively, and the buttress retaining wall 40 is arranged on the rear row of piles 12 and the corresponding connecting beam 14.
[0029] It should be noted that, in order to increase the connection strength, the bottom of the buttress retaining wall 40 is provided with a connection structure, such as an increased step, a cast column, etc. In one improved embodiment of the present application, the bottom of the buttress retaining wall 40 is provided with a plurality of insert bars 41, which are inserted into the rear row of piles 12 and the corresponding connecting beam 14. In addition, the length-to-diameter ratio of the insert bar 41 is not less than 35:1. In this embodiment, the insert bar 41 can be reserved when the rear row of piles 12 and the corresponding connecting beam 14 are cast, and then the insert bar 41 is constructed in the buttress retaining wall 40 during construction.
[0030] In addition, in some embodiments, the insert bar 41 can also be arranged at the connection between the buttress 50 and the top of the double-row pile unit 10, which can increase the overall strength. It should be noted that the outer end of the buttress 50 is flush with the outermost side of the front row of piles 11, which maintains the appearance.
[0031] Further, in the above-mentioned embodiments, the part of the double-row pile unit 10 exposed to the ground reaches more than 60% of the height of the slope protection 20. In order to facilitate the stability between the front row of piles 11 and the rear row of piles 12, the connecting beam 13 is provided with at least two, at least one of which is connected to the top of the front row of piles 11 and the rear row of piles 12, and at least one of which is arranged on the area of the front row of piles 11 and the rear row of piles 12 exposed to the ground. In fact, according to the actual construction requirements and construction conditions, the height difference between the two adjacent connecting beams 13 is controlled to be between 1m-3m, which can ensure the stability of the connection and reduce the construction cost.

In fact, in an improved embodiment of the present application, the buttress retaining wall 40 is provided with an anchoring structure 70 that is inserted into the slope protection 20, which is similar to the anchoring rod 31 described above, so as to improve the overall strength.
[0033] Referring to Figure 1 and Figure 3 In an embodiment of the present application, in order to facilitate drainage, the retaining wall 30 and the buttress retaining wall 40 are both provided with a plurality of drainage holes 50. In addition, in order to avoid soil erosion, the inner side of the retaining wall 30 and the buttress retaining wall 40 is paved with a graded gravel layer 60, and the thickness of the graded gravel layer 60 is paved according to the requirement.
