[0034] See also Figure 1 and Figure 2 As shown, this embodiment provides a buttress-type high retaining wall structure with steel bar bundle reinforcement, including:

[0035] A first retaining wall 100 and a second retaining wall 200, wherein a plurality of the first retaining walls 100 and the second retaining walls 200 are alternately connected in sequence to form an integral retaining wall structure;

[0036] Concrete backfill layers 300, wherein a plurality of the concrete backfill layers 300 are respectively arranged directly below the first retaining wall 100 and the second retaining wall 200, and a water stop strip 310 is arranged at the deformation joint between two adjacent concrete backfill layers 300;

[0037] Wherein, the contact surface between the first retaining wall 100 or the second retaining wall 200 and the overflow weir 400 is provided with a double water-stopping structure.

[0038] The above embodiment provides the first retaining wall 100 and the second retaining wall 200. Since the first retaining wall 100 and the second retaining wall 200 are split structures, the construction difficulty and construction period can be greatly reduced, the fault tolerance rate can be increased, and the construction efficiency can be improved.

[0039] Specifically, when setting up, the first retaining wall 100 and the second retaining wall 200 can be prefabricated in the factory and then assembled on site, or they can be constructed by pouring on site. Since the first retaining wall 100 and the second retaining wall 200 are split-type combination designs, the difficulty of on-site construction can be effectively reduced, the construction speed can be increased, and the construction efficiency can be greatly improved.

[0040] Specifically, the first retaining wall 100 and the second retaining wall 200 both include: a bottom plate 120, which is arranged in the horizontal direction; a back plate 110, which is arranged on the upper side of the bottom plate 120 in the vertical direction, and the back plate 110 intersects the bottom plate 120 vertically; wherein the lower end of the back plate 110 is connected to the upper side of the bottom plate 120 near the right edge, and the length of the bottom plate 120 on the left side of the back plate 110 is greater than the length of the bottom plate 120 on the right side of the back plate 110.

[0041] Specifically, the first retaining wall 100 also includes: a side panel 130, which is a right-angled triangle structure, and the two right-angled sides of the side panel 130 are respectively connected to the upper side surface of the bottom panel 120 and the right side surface of the back panel 110, and the side panel 130 intersects the bottom panel 120 and the back panel 110 perpendicularly in pairs.

[0042] Specifically, the bottom plate 120, the back plate 110 and the side plate 130 are plate-shaped structures cast with reinforced concrete 420, and the bottom plate 120, the back plate 110 and the side plate 130 are cast in one piece, and the steel bars in the bottom plate 120, the back plate 110 and the side plate 130 are arranged in a plum blossom shape when connected. When the bottom plate 120, the back plate 110 and the side plate 130 are arranged, they are arranged in a steel bar bundle reinforcement manner, which can effectively improve the structural safety and reliability of the first retaining wall 100 and the second retaining wall 200.

[0043] Specifically, a plurality of drainage pipes 111 are provided on the back plate 110, and the plurality of drainage pipes 111 are arranged in a plum blossom shape on the back plate 110. When the drainage pipes 111 are arranged, they can be arranged in a plum blossom shape according to a specification of 3m×3m. The drainage pipes 111 are preferably PVC pipes, and their length can be set according to actual conditions.

[0044] It can be seen that the above embodiment can effectively reduce the back water pressure of the first retaining wall 100 and the second retaining wall 200 by providing plum blossom-shaped drainage holes on the back plate 110, thereby improving the structural safety and reliability of the first retaining wall 100 and the second retaining wall 200.

[0045] Specifically, the drain pipe 111 is obliquely installed on the back plate 110, and the height of the right end of the drain pipe 111 is greater than the height of the left end of the drain pipe 111. The obliquely installed drain pipe 111 can effectively improve the drainage efficiency of the drain pipe 111.

[0046] Specifically, the right end of the drain pipe 111 is exposed from the right side of the back plate 110 , and the right end of the drain pipe 111 is sheathed with a non-woven fabric 112 .

[0047] Specifically, the right end of the drain pipe 111 is also covered with a sand and gravel layer 113. The sand and gravel layer 113 can be adhered to the right end of the drain pipe 111 by bonding to effectively form a filtration and reverse osmosis layer.

[0048] It can be seen that the non-woven fabric 112 and the sand and gravel layer 113 can effectively prevent the drain pipe 111 from reverse osmosis. At the same time, it can also filter when the drain pipe 111 drains water, prevent the drain pipe 111 from being blocked, and improve the reliability of the drain pipe 111 when it is working.

[0049] Specifically, a first rubber water stop 401 is provided at the deformation joint between the first retaining wall 100 or the second retaining wall 200 and the concrete foundation 410 of the overflow weir 400 .

[0050] Specifically, reinforced concrete 420 is arranged above the concrete foundation 410 of the overflow weir 400, and a copper waterstop 403 and a second rubber waterstop 402 are arranged in parallel between the first retaining wall 100 or the second retaining wall 200 and the reinforced concrete 420 of the overflow weir 400, and the second rubber waterstop 402 is located directly below the copper waterstop 403.

[0051] It can be understood that in the above embodiments, by setting the first retaining wall 100 and the second retaining wall 200, a plurality of the first retaining walls 100 and the second retaining walls 200 are alternately connected in sequence to form an integral retaining wall structure, a plurality of the concrete backfill layers 300 are respectively arranged directly below the first retaining wall 100 and the second retaining wall 200, and a water stop is arranged at the deformation joint between two adjacent concrete backfill layers 300. The first retaining wall 100 and the second retaining wall 200 can be prefabricated in a factory or cast on site. Since the first retaining wall 100 and the second retaining wall 200 are split structures, the construction difficulty and construction period can be greatly reduced, the fault tolerance rate can be increased, and the construction efficiency can be improved.
