Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so as to provide a better understanding of the concept of the present utility model, the technical problem solved, the technical features constituting the technical solution and the technical effects brought about.

[0021] like Figures 1-4 As shown, a roadbed treatment structure for soft geological conditions includes a reinforcement structure, a waterproof layer 2, a geogrid 3, a sand and gravel layer 4, a pavement structure layer 5, and a drainage structure.

[0022] The reinforcement structure includes a reinforcement plate 11, a crushed stone layer 12, a lightweight concrete slab 13, and bored piles 14; the reinforcement plate 11 is placed above the soft base layer 7, and the bored piles 14 are vertically placed below the reinforcement plate 11 and inserted into the soft base layer 7; the crushed stone layer 12 is placed above the reinforcement plate 11; and the lightweight concrete slab 13 is placed above the crushed stone layer 12.

[0023] The waterproof layer 2, geogrid 3, sand and gravel layer 4, and pavement structure layer 5 are arranged in sequence from bottom to top; the waterproof layer 2 is placed on top of the lightweight concrete slab 13;

[0024] The drainage structure includes a drainage pipe 61, a left drainage seat 63, and a right drainage seat 64. The left drainage seat 63 is located on the left side of the reinforcement structure. The upper right part of the left drainage seat 63 is connected to the top of the road structure layer 5, and the lower right part is connected to the bottom of the reinforcement plate 11. The front end of the left drainage seat 63 is provided with a water outlet 65. The right drainage seat 64 is the same as the left drainage seat 63 and is symmetrically located on the right side of the reinforcement structure. The drainage pipe 61 is buried in the crushed stone layer 12, and both the left and right ends are provided with drainage outlets 66, which are connected to the left drainage seat 63 and the right drainage seat 64 respectively.

[0025] In this invention, a reinforcing plate 11 is first installed above the soft base layer 7, and a bored pile 14 below the reinforcing plate 11 is inserted into the soft base layer 7 for fixation. A crushed stone layer 12 is laid above the reinforcing plate 11, and a lightweight concrete slab 13 is installed above the crushed stone layer 12. Simultaneously with laying the crushed stone layer 12, a drainage pipe 61 is installed inside the crushed stone layer 12, which stabilizes the soft base layer 7 and improves its load-bearing capacity. A waterproof layer 2 is laid above the lightweight concrete slab 13 to prevent water seepage into the soft base layer 7, protecting the subgrade and pavement structure from water damage. A geogrid 3 is laid on the crushed stone layer 12, and a sand and gravel layer 4 is laid on top of the geogrid 3, which effectively ensures the completion of the pavement, improves the stability and safety of the subgrade, and effectively strengthens the overall strength of the soft base layer 7. A pavement structure layer 5 is then installed on top of the sand and gravel layer 4 to allow vehicle passage. After the drainage pipe 61 is laid within the crushed stone layer 12, the drainage pipe 61 drains the water in the crushed stone layer 12 into the drainage seat 61 through the drainage outlet 66. The water can be drained into either the left drainage seat 63 or the right drainage seat 64. The water accumulated in the drainage seat 61 is discharged through the outlet 65 to the municipal drainage system, thus achieving the reinforcement of the entire roadbed. The lightweight concrete slab 13 and the reinforcing plate 11 can also protect the drainage pipe 61.

[0026] like Figure 3 As shown, in a preferred embodiment, a one-way valve 67 is provided at the drain outlet 66 of the drain pipe 61. In this embodiment, after the drain pipe 61 is equipped with the one-way valve 67, the one-way valve 67 can prevent water from the drain seat 61 from flowing back into the sand and gravel layer 4 and causing damage.

[0027] like Figure 2 As shown, in a preferred embodiment, multiple bored piles 14 are provided. In this embodiment, to increase the stability of the structure, multiple bored piles 14 are provided, which work together to improve the stability of the device.

[0028] like Figure 1 As shown in the preferred embodiment, the left drainage seat 63 is inclined, with the left side lower than the right side. Multiple drainage covers are hinged to the top of the left drainage seat 63, and each drainage cover has multiple drainage slots. In this embodiment, with the left drainage seat 63 inclined, the left side is lower than the road surface structure layer 5. Water on the road surface structure layer 5 will also enter the left drainage seat 63 through the drainage covers and drainage slots, thereby achieving drainage and preventing damage to the road surface due to excessive rainfall. The right drainage seat 64 is configured similarly, increasing drainage efficiency.

[0029] like Figure 3 As shown, in a preferred embodiment, a filter screen 62 is provided below the drain cover. In this embodiment, after the filter screen 62 is provided, it can filter out debris and prevent blockage in the left drain seat 63 and the right drain seat 64.

In this embodiment, the reinforcement columns 8, when inserted into the soft base layer 7, enhance the stability of the left drainage seat 63 and the right drainage seat 64.
