DETAILED DESCRIPTION

[0021] The utility model is further described below with reference to the drawings.

[0022] In order to make the utility model's purpose, technical scheme and advantage more clearly, the following combines the drawing and example, and this utility model carries out further detailed explanation. It should be understood that the specific example described here is only used to explain the utility model, and is not used to limit the utility model.

[0023] As Figures 1-2 The utility model provides a highway crash barrier.

[0024] The highway crash barrier is used for safety protection on the outside of the highway. The crash barrier 5 is arranged at the edge of the shoulder retaining wall cap 7. An extending wall is arranged outside the crash barrier 5. The extending wall and the side wall of the crash barrier 5 form a planting groove 1 with an opening upward. A through hole is formed in the extending wall at the middle and lower part of the planting groove 1 as a drain hole. The extending wall inner steel bars N7, N8 and N9 and the crash barrier inner steel bars N3, N4 and N5 are fixedly connected.

[0025] In the application, the extending wall is arranged outside the crash barrier 5, and the extending wall and the crash barrier 5 form the planting groove 1. The planting groove 1 is used for greening and planting on the outside of the highway. Compared with the hanging flower basket mode, the maintenance is convenient, and the safety performance is higher. The extending wall inner steel bars and the crash barrier inner steel bars are fixedly connected, so that the integrated connection strength is improved, and synchronous construction is facilitated. The drain hole is arranged at the middle and lower part of the planting groove 1, so that the drainage in the planting groove 1 is smooth.

[0026] Generally, the shoulder retaining wall cap 7 is arranged above the shoulder retaining wall body 8.

[0027] As Figure 1 and Figure 2 As shown in the drawings, N1, N2 and N6 are foundation bars, N3, N4 and N5 are crash barrier inner steel bars, and N7, N8 and N9 are extending wall inner steel bars. The crash barrier inner steel bars N3, N4 and N5 and the extending wall inner steel bars N7, N8 and N9 are fixedly connected to form an integral whole, and are firmly connected with the foundation bars N1, N2 and N6. In practice, after the steel bars are arranged, the formwork is installed according to the size requirements, and the concrete is poured. The crash barrier 5 and the extending wall are formed synchronously.

[0028] In the embodiment, the extending wall comprises an outward extending section 0 and an upward extending section 9, the outward extending section 0 starts from the outer wall of the crash barrier 5, and the upward extending section 9 starts from the end of the outward extending section 0 away from the crash barrier 5.

[0029] As shown in the figure, in the embodiment, the outward extending section 0 is horizontally arranged, and the upward extending section 9 is vertically arranged. It is obvious that the upward extending section 9 can be arranged obliquely upward. Figure 1

[0030] In some embodiments, the extending wall does not comprise a horizontally arranged section, can be configured as an entire section arranged obliquely upward, or a section in the shape of a circular arc. It is appropriate to form suitable planting grooves 1, which is not specifically limited here.

[0031] In the embodiment, the drainage hole is arranged at the middle-lower part of the upward extending section 9. In this way, the drainage hole can be implemented to make the drainage of the planting groove 1 unobstructed, and the lower part of the drainage hole remains moist, forming an environment in which the upper part of the soil in the planting groove 1 is dry and the lower part is moist, thereby improving the survival rate of plants in the planting groove 1, reducing maintenance, and reducing project investment. In the embodiment, the distance between the drainage hole and the bottom of the planting groove 1 is 20 cm.

[0032] In the embodiment, a waterproof layer 3 is further arranged on the inner wall below the drainage hole in the planting groove 1. In order to further avoid the loss of water below the drainage hole.

[0033] In the embodiment, a filter bag 4 is arranged at the end of the drainage hole communicating with the inside of the planting groove 1. Through the arrangement of the filter bag 4, the loss of nutrient soil is prevented, and the blockage of the drainage hole is avoided. In the embodiment, after the extending wall and the crash barrier 5 are poured with concrete to reach the strength, the planting groove 1 is backfilled with light nutrient soil, and the filter bag 4 is placed at the end of the planting groove 1 on one side of the drainage hole.

[0034] Further, plants are planted in the planting groove 1. In the selection of plants, plants with good stress resistance, strong adaptability, low maintenance, and high ornamental value should be selected. It is ensured that better landscape effects can be presented in harsh natural environments. Suitable plant species can be selected according to the specific implementation of the project, mainly perennial plants, first selected liana or plants with climbing properties, for example, leaf flowers (trigonella), many-flowered roses, Chinese roses, etc. Herbaceous plants with creeping properties can also be used, for example, overpass yellow and bishop weed, etc. The landscape along the highway is improved, and the hardening crash barrier 5 is also beautified.

[0035] In the embodiment, the extending wall is arranged as multiple sections arranged at intervals in the length direction of the road surface 6. In this way, multiple planting grooves 1 arranged at intervals in the length direction of the road surface 6 are obtained, which is convenient for construction and maintenance.

[0036] ​In the embodiment, the drainage hole is internally fixed with a drainage pipe 2, which is communicated with the planting groove 1 and the external space, so as to further facilitate the maintenance and cleaning of the drainage hole.

[0037] In the embodiment, the height of the top surface of the anti-collision wall 5 relative to the road surface 6 is 80-100 cm, and the top surface of the extension wall is flush with the top surface of the anti-collision wall 5. In this way, the height is adapted to the height of the line of sight of the driver, good visual effects are achieved, and visual fatigue is avoided during long-time driving of the vehicle.

[0038] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
