DETAILED DESCRIPTION

[0020] The first embodiment of the present application is:

[0021] See also Figure 1~Figure 2 , Figure 1 is a schematic diagram of the overall structure of the first embodiment of the present invention, Figure 2 It is an overall cross-sectional view of the first embodiment of the present invention. The present invention provides an overhead pile-plate structure and a transition section structure of an embankment, including a foundation 101, a fill layer 102, an embankment transition section 103, a closing layer 104, a bearing plate 105 and a stabilizing assembly 106. The foundation 101 has a groove 115. The stabilizing assembly 106 includes a fixed plate 107, a supporting pile 108, a pressure body 109 and a slope 110. The fixed plate 107 has a slot 116. The fixed plate 107 includes a protrusion 111 and a plate body 112. The pressure body 109 includes a crushed stone layer 113 and a concrete layer 114.

[0022] According to this specific embodiment, the fill layer 102 is fixedly connected to the foundation 101 and is located on the side of the foundation 101. The embankment transition section 103 is arranged on the side of the foundation 101. The closed layer 104 is fixedly connected to the embankment transition section 103 and is located on the side of the embankment transition section 103. The bearing plate 105 is arranged on the side of the embankment transition section 103. The embankment transition section 103 is placed on one side of the foundation 101. The bearing plate 105 is placed on the embankment transition section 103 to improve the safety of the transition section structure. The transition section is closed by the closed layer 104 to prevent debris from entering and affecting the transition section structure.

[0023] Among them, the fixed plate 107 is fixedly connected to the bearing plate 105 and is located on the side of the bearing plate 105. The fixed plate 107 has a slot 116. The supporting pile 108 is fixedly connected to the fixed plate 107 and to the foundation 101, and is located in the groove 115 and the slot 116. The pressing body 109 is fixedly connected to the supporting pile 108 and to the fixed plate 107, and is located on the side of the supporting pile 108. The supporting pile 108 is placed between the groove 115 and the slot 116 to support the fixed plate 107, so that the fixed plate 107 is more stable when the bearing plate 105 is placed. The pressing body 109 is placed between the supporting pile 108 and the foundation 101, so that the supporting pile 108 is more firm to avoid displacement after long-term use.

[0024] Secondly, the slope 110 is fixedly connected to the foundation 101 and is located on the side of the foundation 101. The slope 110 can reinforce the transition section structure and improve the stability of the transition section structure.

[0025] Furthermore, the protrusion 111 is slidably connected to the closed layer 104 and is located on one side of the closed layer 104, and the plate body 112 is fixedly connected to the supporting plate 105 and is located on the side of the supporting plate 105. By sliding the protrusion 111 into the closed layer 104, the plate body 112 is more stable when the supporting plate 105 is placed, thereby improving the stability of the transition section structure.

[0026] At the same time, the gravel layer 113 is fixedly connected to the foundation 101 and is located on one side of the foundation 101, and the concrete layer 114 is fixedly connected to the gravel layer 113 and is located on the side of the gravel layer 113. The support piles 108 are reinforced by the gravel layer 113 and then reinforced by the concrete layer 114, which can compact the support piles 108 to prevent the support piles 108 from displacement and reduce the stability of the transition section structure.

[0027] The present embodiment describes a transition section structure between an overhead pile-plate structure and an embankment, wherein the support pile 108 is placed in the groove 115 of the foundation 101, the gravel layer 113 is placed between the support pile 108 and the foundation 101, the support pile 108 is stabilized, and the support pile 108 is sealed and reinforced by the concrete layer 114 to prevent the support pile 108 from being displaced after long-term use, the slot 116 of the plate body 112 is aligned with the support pile 108, and the protrusion 111 is slid into the sealing layer 104, so that the plate body 112 can remain stable after the bearing plate 105 is placed, thereby preventing displacement after long-term wear and reducing the stability of the transition section.

[0028] The second embodiment of the present application is:

[0029] See also Figure 3 , Figure 3 The present invention provides an overhead pile-sheet structure and a transition section structure of an embankment, which further includes a waterproof component 201 , which includes a waterproof membrane 202 , an impermeable layer 203 , a permeable layer 204 and a drainage pipe 205 .

[0030] For this specific embodiment, the waterproof component 201 is arranged on the side of the stabilizing component 106. The waterproof component 201 can prevent water from penetrating upward through the foundation 101 and soaking into the stabilizing component 106 or seeping in from the outside after a long period of time, thereby reducing the stability of the transition section structure.

[0031] The waterproof membrane 202 is fixedly connected to the slope 110 and is located on the side of the slope 110. The anti-seepage layer 203 is fixedly connected to the gravel layer 113 and is located on the side of the gravel layer 113. The waterproof membrane 202 can prevent rainwater from penetrating into the embankment transition section 103 through the slope on rainy days. The anti-seepage layer 203 can prevent groundwater from penetrating upward into the stabilizing component 106 through the foundation 101 after long-term use, thereby reducing the stability of the transition section structure.

[0032] Secondly, the water-permeable layer 204 is fixedly connected to the anti-seepage layer 203 and is located on one side of the anti-seepage layer 203. The drainage pipe 205 is connected to the water-permeable layer 204 and is located on one side of the water-permeable layer 204. Some water passing through the anti-seepage layer 203 is absorbed by the water-permeable layer 204 and discharged through the drainage pipe 205, thereby preventing the water passing through the anti-seepage layer 203 from penetrating deeper.

[0033] The transition section structure of an overhead pile-board structure and an embankment described in this embodiment can prevent rainwater from seeping into the fill layer 102 on rainy days through the waterproof membrane 202, and the anti-seepage layer 203 can prevent groundwater from seeping upward, affecting the stability of the stabilizing component 106 through the foundation 101. Part of the water that passes through the anti-seepage layer 203 is absorbed by the permeable layer 204 and discharged through the drain pipe 205, thereby preventing the water that passes through the anti-seepage layer 203 from continuing to seep upward.

[0034] What is disclosed above is only one or more preferred embodiments of the present application, and cannot be used to limit the scope of rights of the present application. Ordinary technicians in this field can understand that all or part of the processes of implementing the above embodiments and equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
