Detailed Description
In order to make the present invention better understood by those skilled in the art, the present invention will be further clearly and completely described below with reference to the accompanying drawings and embodiments. In addition, the features of the embodiments and examples in the present application may be combined with each other without conflict.
The utility model relates to a typical embodiment provides a geogrid side slope protective structure, as shown in fig. 1, include the three-dimensional vegetation net 2 of laying from the top of slope 101 of road engineering side slope 1 to toe cap 102, the top of slope is provided with the coping 3 that is used for fixed three-dimensional vegetation net 2 top edge, and toe cap portion is provided with the banket 4 that is used for fixed three-dimensional vegetation net 2 bottom edge, banket 4 sets up in the toe cap inboard, and three-dimensional vegetation net 2 bottom edge links to each other through U type anchor nail 5 with banket 4.
The three-dimensional vegetation net is a commercial geosynthetic material. The press top 3 and the foot guard 4 are both formed of concrete.
The utility model discloses an utilize active plant and combine three-dimensional vegetation net, construct a protection system who has self growth ability in domatic, consolidate the side slope through the growth of plant. According to the characteristics of the landform, the soil quality and the regional climate of the side slope, covering a layer of geosynthetic material on the surface of the side slope, and planting various plants according to a certain combination and spacing. The purpose of root system reinforcement and stem leaf erosion prevention is achieved through the growth activity of plants, dense vegetation cover can be formed on a slope surface through the treatment of an ecological slope protection technology, root systems with root-coiling staggered joints are formed on a surface soil layer, the erosion of storm runoff on a side slope is effectively inhibited, the shear strength of a soil body is increased, the pore water pressure and the soil body self-gravity are reduced, and therefore the stability and the erosion resistance of the side slope are greatly improved.
In this embodiment, the three-dimensional vegetation net is fixed by the roof 2 and the foot guards 4 to prevent the displacement of the three-dimensional vegetation net 2. Particularly, the toe cap 102 is connected and fixed with the protection foot 4 and the three-dimensional vegetation net 2 through the U-shaped anchor 5, the front end of the U-shaped anchor 5 is inserted into the protection foot 4, connection is firm, the operation mode is simple, and construction efficiency is improved.
As shown in fig. 2, the three-dimensional vegetation net 2 is connected with the road engineering side slope 1 through U-shaped anchors 5. Specifically, the U-shaped anchors are arranged and fixed in a quincunx shape during laying, the distance between the U-shaped anchors 5 for connecting the three-dimensional vegetation net 2 and the road engineering side slope 1 is 1.5 m, the attaching tightness of the slope and the three-dimensional vegetation net is further improved, and the effect of solidifying the soil body is achieved.
After the three-dimensional vegetation net 2 is constructed, a covering soil layer is laid on the upper part of the three-dimensional vegetation net 2. Covering 15cm-25cm of planting soil relatively, and paying attention to the fact that the vegetation net and the slope surface are flat when in construction.
As shown in fig. 1, the protection feet 4 are arranged at the inner side of the intersection of the slope toe 102 and the horizontal ground 6, so that the displacement of the three-dimensional vegetation net caused by the erosion of the slope toe by rainwater can be avoided, and the fixing effect of the three-dimensional vegetation net is further improved.
During construction, firstly, the slope is processed according to data given by a drawing through machinery, after the mechanical processing is finished, the positions which are not processed in place by the machinery are processed in a manual blind mode, and after the early-stage work is finished, the construction of the three-dimensional vegetation net 2 is started. And during laying, the three-dimensional vegetation net 2 on the slope top is laid and stretched from the slope top 101 to the slope toe 102, and is temporarily fixed. After the fully unfolded state, the size is cut to be proper according to the size of the slope. And constructing slope top coping concrete, after the coping concrete reaches initial setting, starting to prick the U-shaped anchors 5, arranging the U-shaped anchors 5 in a quincunx shape at an interval of 1.5 meters, and paying attention to the anchor setting effect during construction. And finally, constructing a concrete toe guard of the slope toe, and paying attention to the fact that the vegetation net is flat with the slope surface during construction.
The scope of the invention is not limited to the above embodiments, and various modifications and changes may be made by those skilled in the art, and any modifications, improvements and equivalents made within the spirit and principle of the invention are intended to be included within the scope of the invention.
