Medium-strong expansion rock-soil slope protection structure

Technical Field

The utility model relates to the technical field of slope protection device equipment, in particular to a medium-strong expansion rock-soil slope protection structure.

Background

The expansive rock soil is also called expansive soil, and is a special soil, and is a geologic body which is formed under the geological action, mainly comprises clay minerals with strong hydrophilicity, has multiple cracks and has obvious expansibility. Because of the characteristic of strength attenuation caused by irregularly distributed cracks and repeated expansion and contraction deformation in soil, serious damage is often brought to human engineering construction, and a plurality of geological disasters are caused.

The united states engineering community calls expansive soil a "hidden disaster". The japanese engineering community calls that expansive soil is "hard to cope with soil" and "soil with many problems". Disaster caused by expansive soil in China is more striking and frightening, and the building area of China, which is harmful to the expansive soil foundation, reaches 1000 ten thousand m ² The economic loss caused by road diseases such as slope instability, roadbed deformation, pavement damage, structure cracking and collapse caused by expansive soil in the road engineering is also huge.

Due to the water absorption expansion, water loss shrinkage and repeated deformation of the expansion soil, the soil layer can shrink when the slope is not contacted with rainwater for a long time, and the soil naturally runs off, so that the slope is hollow and collapses, and the soil layer can be very inconvenient for constructors in later period. Therefore, the adoption of convenient and effective slope protection measures for protecting the stability of the slope becomes a problem to be solved urgently by the person skilled in the art.

Example 1

As shown in the figure, the medium-strong expansion rock-soil slope protection structure comprises a slope body 1, wherein a plurality of mounting bars 2 are arranged on the slope surface of the slope body 1, and fixing rods 7 are arranged at the bottoms of the mounting bars 2. The fixing rod 7 is inserted into the side slope body 1 to fix the mounting strip 2 on the slope surface of the side slope body 1, and the fixing rod 7 is of a T-shaped structure, so that the inner contact area between the fixing rod and the side slope body 1 is larger, and the mounting strip 2 is more stable on the slope surface of the side slope body 1.

The two sides of each mounting strip 2 are respectively provided with a slot 9, a plurality of mounting strips 2 are mounted into a plurality of quadrilateral frames, and two adjacent mounting strips 2 are fixedly connected through a zigzag connector. The diamond-shaped reinforcing steel bar nets 3 are arranged in the quadrangular frames, and inserting blocks 10 matched with the inserting grooves 9 on the mounting bars 2 are arranged around the diamond-shaped reinforcing steel bar nets 3. The installation strip 2 is connected with the diamond-shaped reinforcing steel bar net 3 through the slot 9 and the insert block 10, so that the diamond-shaped reinforcing steel bar net 3 can be conveniently detached and installed when needed. The diamond-shaped reinforcing mesh 3 not only can effectively play a role in reinforcing and protecting the slope surface of the slope body 1, but also can play a role in greening without affecting the normal growth of vegetation in the diamond.

The fixing groove 4 is arranged on the upper surface of the diamond-shaped reinforcing steel bar net 3, the fixing screw 5 is arranged at the top of the fixing groove 4, and when the fixing groove 4 is arranged on the upper surface of the diamond-shaped reinforcing steel bar net 3, the fixing screw 5 penetrates through the diamond-shaped reinforcing steel bar net 3 and is inserted into the side slope body 1 through the fixing screw 5, so that the diamond-shaped reinforcing steel bar net 3 is fixed. When the soil layer is contracted, later constructors only need to take down the fixing screws 5 at the top of the fixing groove 4 to detach the fixing groove 4 and then take down the diamond-shaped reinforcing steel bar net 3.

The fixed slot 4 both sides are equipped with drainage network 8, when there is too much rainwater, drainage network 8 can effectually drain to the rainwater in the diamond reinforcing bar net 3 to avoid the rainwater in the diamond reinforcing bar net 3 too much, not only can effectually prevent too much rainwater to permeate side slope 1, also do benefit to vegetation normal growth on the side slope 1 simultaneously.

The bottom of the side slope body 1 is provided with a water drainage groove 6, one side of the water drainage groove 6 close to the side slope body is provided with a fixing rod 7, and the fixing rod 7 is inserted into the side slope body 1. The fixing rod 7 with the T-shaped structure ensures that the drainage groove 6 is more stable on the slope surface of the side slope body 1. When rainwater on the diamond-shaped reinforcing mesh 3 flows into the drainage groove 6 through the drainage mesh 8, rainwater can be prevented from flowing onto a road surface, and water accumulation phenomenon is caused, so that driving safety is ensured.

The diamond-shaped reinforcing mesh 3 is fixedly connected through the mounting strip 2 and the fixing groove 4, the side slope body 1 can be protected and reinforced, excessive rainwater can be discharged through the drainage mesh 8 and the drainage groove 6, and the side slope body 1 is prevented from being permeated by excessive rainwater. When the side slope body 1 is required to be filled in the later period, the fixing groove 4 is only required to be disassembled, and the diamond-shaped reinforcing mesh 3 is required to be taken down.
