DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Usually, the components of the embodiments of the present utility model described and illustrated in the drawings here can be arranged and designed in various different configurations.

[0022] Accordingly, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0023] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0024] The following is further described in conjunction with specific embodiments. Referring to Figures 1 - 4 As shown, this embodiment is a road protection structure, including a roadbed main body 1, which includes a plurality of steel pipe piles 2. The steel pipe piles 2 are vertically driven into the side of the roadbed main body 1. A plurality of anchor rods 4 are installed on the side of the roadbed main body 1; a retaining wall 3, which is poured against the side of the roadbed main body 1 and forms an integral structure with the anchor rods 4; a foundation pit 5, which is dug beside the roadbed main body 1, and a bearing platform 6 connected to the retaining wall 3 is poured in the foundation pit 5. Specifically, first, a plurality of steel pipe piles 2 are evenly inserted into the roadbed main body 1 on the side close to the slope to play a certain role in blocking the lateral displacement of the soil mass. After cleaning the slope, the anchor rods 4 are horizontally and laterally driven into the slope evenly, and a vertical retaining wall 3 is formed by pouring with a formwork. The foundation pit 5 is excavated and poured to form a bearing platform 6 that supports the bottom end of the retaining wall 3, so as to form an effective lateral support on the side of the slope, effectively avoiding the collapse and landslide of the road and improving the driving safety.

[0025] It should be noted that the foundation pit 5 can be filled after completion.

[0026] As Figure 1 and Figure 2 shown, a water collecting trough 61 is provided on the surface of the bearing platform 6 in this embodiment; at least one water guide pipe 7, one end of which passes through the retaining wall 3 and is placed in the roadbed main body 1, and the other end of which is placed in the water collecting trough 61; and the water guide pipe 7 is inclined. As Figure 4 shown, and a water outlet 72 is provided at the lower end of the water guide pipe 7, and the water outlet 72 is arranged above the water collecting trough 61; the water collecting trough 61 is connected to a drain pipe 9 extending into the soil. Specifically, the water guide pipe 7 is set to be inclined, one end of which is stuck against the water collecting trough 61, and the other end has a certain supporting effect on the retaining wall 3. In addition, the water guide pipe 7 diverts and inputs a part of the rainwater entering the roadbed main body 1 into the water collecting trough 61, reducing the water content in the roadbed main body 1, and the weight is relatively lower, and it is less likely to slide along the side of the slope. The water collecting trough 61 discharges the collected water through the drain pipe 9 in the middle of it out of the bearing platform 6 and infiltrates into the ground to form groundwater.

[0027] Referring to Figure 4As shown, in order to prevent the gravel particles infiltrating into the roadbed main body 1 from blocking the water guide pipe 7, a filter screen cover 71 is installed at one end of the water guide pipe 7 located in the roadbed main body 1. The holes above the filter screen cover 71 are smaller, and the holes below are larger, so as to have good water passing efficiency in rainy days.

[0028] Referring to Figure 1 As shown, in order to prevent the water guide pipe 7 from slipping at the corners of the water collecting tank 61, the water collecting tank 61 is designed as a square groove, the cross-section of the water guide pipe 7 is a square pipe, and one end of the water guide pipe 7 is an inclined opening that fits with the bottom of the water collecting tank 61.

[0029] Referring to Figure 1 and Figure 2 As shown, in order to wrap the slope and make its surface form an integrated effect, a wire mesh 10 is provided between the retaining wall 3 and the roadbed main body 1. The anchor rod 4 passes through the holes of the wire mesh 10. Before pouring the retaining wall 3, after driving in the anchor rod 4 and the wire mesh 10, the slope surface is first preliminarily sprayed to form a concrete layer.

[0030] In order to improve the lateral pressure resistance strength of the retaining wall 3, at least two reinforcing square tubes 8 are provided at the bottom of the retaining wall 3, and the reinforcing square tubes 8 are arranged horizontally.

[0031] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
