Description

Technical Field

[0001] The invention relates to the technology of planting grass on the roadbed slope and preventing water seepage. Background Art

[0002] As an important part of railways and highways, roadbed slopes play an important role in ensuring the stability of railways and highways. The protection of roadbed slopes is an indispensable engineering and technical measure for road engineering. Slope protection can protect the slope surface from rain erosion, mitigate the impact of temperature differences and humidity changes, and protect the overall stability of roadbed slopes. At present, the commonly used slope protection mainly includes two forms: plant protection and engineering protection. Combined with the comprehensive analysis of factors such as project cost, protection effect, and beautification and coordination of the natural environment, the slope grass planting method in plant protection is the best method and the most commonly used method at this stage.

[0003] The biggest disadvantage of using slope grassing for roadbed slope protection is that it cannot prevent rain, snow, etc. from infiltrating into the roadbed along the slope. When these water penetrates into the roadbed, the water content of the roadbed filler will increase. In particular, the surface of the slope is covered with grass, and the water is not easy to evaporate. If there is a lot of rain in the area, the water content and seepage depth of the roadbed filler will gradually increase. Generally, this will not affect the stability of the roadbed. However, if the area belongs to a seasonal frozen soil area, the roadbed filler will frost heave in winter and melt in spring. The freeze-thaw cycle will cause road diseases and have a great impact on driving safety and comfort. Therefore, a device that can effectively plant grass on the roadbed slope and waterproof the slope is urgently needed at this stage. Summary of the invention

[0004] The purpose of the present invention is to provide a device which can effectively carry out grass planting on the roadbed slope and prevent water seepage on the slope.

[0005] The present invention is a grass planting and water seepage prevention device for roadbed slope and an application method. The grass planting and water seepage prevention device for roadbed slope consists of a grass planting box 1 and a card slot 2. The grass planting box 1 consists of a front wall 3, a rear wall 4, a side wall 5 and a bottom plate 6. The front wall 3, the rear wall 4 and the side wall 5 are composed of flat plates of equal thickness, and the bottom plate 6 is thinner at the end of the front wall 3 than at the end of the rear wall 4, forming a slope of 1:1 from the back to the front. i The slope of 1; the length of the grass box 1 is l 1, width is d 1, height is h 1. Wall thickness c 1. The thickness of the bottom plate 6 at the front wall 3 is c 1, the thickness at the rear wall 4 is c 2, then c 2= c 1+( d 1-2c 1) / i 1.

[0006] The application method for roadbed slope grass planting and anti-seepage device comprises the following steps:

[0007] Step (1) According to the slope of the roadbed slope 1: i 3. Determine the height of the grass box 1 h 1 and width d 1. Make h 1: d 1=1: i 3. Length of grass box 1 l 1Determined according to the specific conditions during on-site construction;

[0008] Step (2) making the roadbed slope into steps 18, wherein the height and width of each step 18 are the same as the height and width of the grass planting box 1;

[0009] Step (3) first place the bottom row of grass planting boxes 1; when placing a single grass planting box 1, place the grass planting box 1 from top to bottom after the position is determined and cannot be dragged;

[0010] Step (4) After a row of grass planting boxes 1 is placed, the side walls 5 of two adjacent grass planting boxes 1 are clamped in sequence using the clamping slots 2, and soil 7 is placed in the grass planting boxes;

[0011] Step (5) Repeat the operations of step (4) and step (5) to place a row of grass planting boxes 1 until all the grass planting boxes on the entire slope are placed, and then grass planting can be carried out.

[0012] The beneficial effects of the present invention are: by arranging grass planting and waterproofing devices on the roadbed slope, not only can the purpose of beautifying the environment and preventing the roadbed slope from being washed away be achieved, but also the water on the slope can be prevented from penetrating into the roadbed, causing excessive moisture in the filler in the roadbed and affecting the performance of the roadbed. In particular, when railways and highways are in seasonal frozen soil areas, the device can prevent roadbed diseases caused by excessive moisture content in the roadbed. The present invention has a relatively simple structure, strong practicality, and high environmental protection and application value. BRIEF DESCRIPTION OF THE DRAWINGS
