Description
Technical Field
The utility model relates to a technique of side slope grass planting and prevention of seepage water of road bed.
Background
The subgrade side slope is used as an important component of railways and highways, and plays an important role in ensuring the stability of the railways and the highways. The protection of the roadbed slope is an indispensable engineering technical measure for road engineering. The protection of the side slope can protect the surface of the side slope from being washed away by rainwater, slow down the influence of temperature difference and humidity change and protect the overall stability of the roadbed side slope. The slope protection adopted at present mainly comprises two forms of plant protection and engineering protection, and the slope grass planting mode in the plant protection is an optimal mode and is the most mode adopted at present by combining the comprehensive analysis of factors such as engineering cost, protection effect, beautifying and coordinating natural environment and the like.
The slope grass is adopted to protect the roadbed slope, and the biggest defect is that rain, snow, water and the like cannot be prevented from permeating into the roadbed along the slope. This water content, after penetrating into the subgrade, increases the water content of the subgrade filler. Especially, the side slope surface is covered by grass, and the moisture is not easy to volatilize. If the area rainwater is more, then the water content and the infiltration degree of road bed filler then can increase gradually, and this can not influence the stability of road bed under the general condition. However, if the area belongs to a seasonal frozen soil area, the roadbed filling material is frozen and swelled in winter, and is melted in spring. The freeze-thaw cycle causes diseases of roads, and has great influence on the safety and comfort of driving. Therefore, a device capable of effectively planting grass on the roadbed slope and simultaneously preventing the slope from being waterproofed is urgently needed at present.
Disclosure of Invention
The utility model aims at providing a can effectively carry out the device that the side slope infiltration is prevented again simultaneously to the side slope grass planting.
The utility model relates to a device for planting grass on a side slope of a roadbed and preventing water seepage, which consists of a grass planting box 1 and a clamping groove 2; the grass planting box 1 is composed of a front wall 3, a rear wall 4, side walls 5 and a bottom plate 6, the front wall 3, the rear wall 4 and the side walls 5 are composed of flat plates with equal thickness, and the bottom plate 6 is thinner at the end of the front wall 3 than the end of the rear wall 4 to form a structure consisting of a rear partForward slope is 1:i 1the slope of (a); the length of the grass planting box 1 isl 1Width ofd 1Height ofh 1Wall thickness ofc 1The thickness of the bottom plate 6 at the front wall 3 isc 1At the rear wall 4, a thickness ofc 2Then there isc 2=c 1+(d 1-2c 1)/i 1。
The utility model has the advantages that: by arranging the grass planting and waterproof devices on the roadbed side slope, the purposes of beautifying the environment and preventing the roadbed side slope from being flushed can be achieved, and the influence on the performance of the roadbed due to the overlarge water content of the filler in the roadbed can be prevented when the water on the side slope permeates into the roadbed. Particularly, when railways and highways are in seasonally frozen soil areas, the device can prevent roadbed diseases caused by excessive moisture content in the roadbed. The utility model discloses a structural style is fairly simple, and the practicality is strong, has higher environmental protection and using value.
