Technical Field
The utility model relates to a slope protection technical field, especially a flexible three-dimensional protection network of constituteing by flexible muscle honeycomb check room.
Background
The ecological restoration and the ecological greening of the side slope at the present stage are mainly realized by using soil dressing spray seeding and a series of improvement technologies (including adding various materials which reduce the weight and improve the viscosity, such as fibers, rice hulls, adhesives, concrete and the like, into a matrix, or reducing the slope gradient in a local range by using materials such as ecological bars, wood boards, geocells and the like and then carrying out a soil dressing spray seeding process).
However, the technology is mainly applied to self-stabilizing soil slopes or low and steep rock slopes, is difficult to implement on high and steep rock slopes, and even if the technology is implemented reluctantly, the soil layer is extremely thin and cannot meet the growth requirements of plants, or the soil layer is easy to peel off under the action of rain erosion, wind erosion and gravity and cannot be used for a long time.
The traditional geocell can be filled with soil after being tiled for slope greening. However, this type of geocell has low strength and insufficient thickness, and is generally used only for 1: a side slope below 1. Meanwhile, because the cells are produced in a sheet mode, when the natural side slope is subjected to uneven side slope conditions, the cells cannot be tiled and fixed, and cannot be applied to high and steep rock side slopes. Similar other technologies have extremely limited adaptability to natural slopes, and the slope cutting machine is generally used after being subjected to standard slope cutting according to requirements.
At present, the side slope protective net is common mainly in the following situations:
firstly, the protective net is made into an integral rigid net shape, and the protective net is suitable for low slope with higher flatness; but be used for unevenness's domatic, then empty concave can not effectively be protected, even if cut the slope and handled when the high slope, because the easy landing of earth when the high slope, again produce empty sunken department.
Secondly, a single grid chamber in the protective net is designed to be rigid and fixed through an anchor rod, when soil at a certain position slides off, force is only concentrated at the grid chamber, and cannot be effectively dispersed, so that the grid chamber is easily broken and damaged.
And thirdly, the anchor rod is used as a stress point of a single cell, the anchor rod is wound by the winding to form the cell, which is more ideal than the second stress condition, but the single cell is stressed, the force is not dispersed, and the installation efficiency is low.

Detailed Description
The invention will be further described with reference to the accompanying drawings, but the scope of the invention is not limited to the following description.
As shown in fig. 1 to 3, a flexible three-dimensional protection net is composed of flexible reinforced honeycomb cells, and the flexible reinforced honeycomb cells are connected to form the flexible three-dimensional protection net. The flexible reinforced honeycomb cell comprises a frame 1 and a net layer 2 arranged in the frame; the frame 1 is formed by splicing a plurality of frame units 3; and the frame unit 3 is woven by a single steel wire.
In this scheme, frame element 3 is two frame limits 301 that are the contained angle and is three horn shapes through the steel wire tensioning, and it still overlaps to be equipped with the cloth of just hindering the nothing to paste its frame limit on frame limit 301, and the non-woven fabrics is fixed through sutural mode. The two frame units 3 are spliced into a frame 1 through connecting rings, and the frame 1 is in a diamond shape.
The connecting ring is shown in fig. 3 and comprises a long waist-shaped piece and a connecting sleeve, wherein the long waist-shaped piece is provided with a notch, and the connecting sleeve is matched with the notch through threads. During installation, the connecting sleeve is screwed to enable the gap to be leaked, the frame unit 3 is clamped in from the gap, then the connecting sleeve is screwed to seal the gap, and connection is convenient.
The flexible reinforced honeycomb cells are connected with a flexible three-dimensional protective net through quick connecting rings. When the flexible three-dimensional protective net is placed on a slope, the steel wire edge which plays a role of tensioning between the two frame edges 301 is in bearing arrangement along the height direction.
When partial soil on the slope tends to slide down, the soil is isolated and held by the flexible reinforced honeycomb cells, and the soil plays a role of pulling the steel wire edge which plays a role of tensioning between the two frame edges 301 due to gravity. Since the frame unit 3 is formed by weaving a single steel wire, it is in a contracted state under the action of a tensile force, and thus a tightening force is generated in the circumferential direction thereof, and then it is dispersedly absorbed by the surrounding frame units 3. Because the single steel wire is woven, the tension force generated on the peripheral side of the steel wire is relatively uniform, and the situation that a certain part is torn due to overlarge stress can not occur; and even if the tightening force of the peripheral side is larger, the single steel wire weaving mode does not cause the fraying. Therefore, the service life of the flexible three-dimensional protective net is prolonged.
In order to further guarantee the service life of the flexible three-dimensional protective net, the following requirements are required: the steel wire used for weaving the frame unit 3 has the tensile strength of more than or equal to 1000Mpa and adopts the tensile strength of more than or equal to 160g/m2The zinc-aluminum alloy coating is subjected to surface corrosion resistance treatment.
In the atress of earth landing trend, the steel wire plays the effect of muscle and bone, but just does not have the cloth of harm simultaneously also can the atress, because the non-woven fabrics receives the solarization for a long time or water erosion, consequently requires: the non-woven fabric is polypropylene fabric with breaking strength not less than 8KN/m, breaking elongation not more than 35% and unit mass of 200/m2Plus or minus 5 percent; the retention rate of ultraviolet resistance strength is more than or equal to 90% in 500h, and the retention rate of acid and alkali resistance strength is more than or equal to 90% in 500 h.
In this embodiment, the mesh layer 2 is one or more of a polygonal iron wire grid, a three-dimensional mesh, a plastic mesh, a geonet, and a microphone pad, and is used for reinforcing foreign soil inside the frame.
When the flexible three-dimensional protective net is placed on a side slope, the flexible three-dimensional protective net is hung on the anchor rods and fixed through the flexible reinforced honeycomb cells in the first row.
Because the frame 1 of the flexible reinforced honeycomb cell is composed of steel wires and non-woven fabrics, the flexibility of the whole cell is very high; in the flexible three-dimensional protective net, when a certain flexible reinforced honeycomb cell is stressed, the force can be transmitted in a large range, so that the force is well dispersed, and the force borne by a single flexible reinforced honeycomb cell is small; compare in traditional rigidity check room, the flexible life who adds muscle honeycomb check room of this scheme obtains improving widely.
The above examples only represent preferred embodiments, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
