Number of patent application 201520543700.5, discloses a kind of geotechnical grid being made up of profiled cross-section cell compartment, Including at least provided with one layer of cell compartment being formed by connecting by polylith cell compartment, the cell compartment includes cell compartment lamellar body and located at cell compartment Junction on body, the cross section of each cell compartment lamellar body between each junction is concavees lens shape cross section, tooth form cross section or ripple Shape wave cross section, the junction of each form lamellar body is provided with reinforcement, each reinforcement vertical region where running through.
Number of patent application 201520959354.9, discloses a kind of geotechnical grid with convex body structure work lattice sheet material, piece The side of material body is provided with salient point, the top of bodies and/or is provided with heel teeth below, is separated by staggeredly between adjacent bodies Be formed by connecting geotechnical grid.
Two patent applications of the above are all increasing filler and geotechnological lattice by way of the setting of sheet material body side surface is raised Stiction between room, and then interlocking, the snap-in force of geotechnical grid and filler are improved to a certain extent, but be due to geotechnique Cell compartment is to filler and in the absence of other active forces, so geotechnical grid is to the interlocking of filler, snap-in force using effect and fails to understand It is aobvious.
Utility model content
There is provided a kind of geotechnical grid with spring steel plate in view of the shortcomings of the prior art the utility model, it is to avoid soil The not good defect of interlocking, snap-in force effect between work cell compartment and filler.
The utility model is achieved by the following technical solution there is provided a kind of geotechnical grid with spring steel plate, its It is characterised by：A kind of geotechnical grid with spring steel plate, including polylith rib tape, the adjacent rib tape be separated by be cross-linked and Into geotechnical grid, it is characterised in that：The rib tape junction is provided with arc elastic steel plate, the arc elastic steel plate recess direction Rib tape junction；The arc elastic steel plate is across junction and the two rib tape connection of two ends respectively with intersecting；The rib tape Interior to be provided with reinforcement, the spring steel plate two ends are affixed with the reinforcement that is provided with rib tape respectively；The arc elastic steel plate table Face is connected with limiting tooth.
Preferably, connected mode is bolt connection between the rib tape.
Preferably, the thickness of the arc elastic steel plate is 2-5mm.
Preferably, the length of the limiting tooth differs.
Preferably, the rib tape upper end is provided with sawtooth, the sawtooth is discontinuous sawtooth, and sawtooth spacing is more than sawtooth Width.
Preferably, the angle of the sawtooth pointed projections is 60 °~120 °.
Preferably, the rib tape is provided with hole.
The beneficial effects of the utility model are：
1st, the arc elastic steel plate in compressive state has the trend of a recovery diastole state, that is to say, that arc bullet Property steel plate can overcome the pressure that rib tape is produced to it, rib tape is done work, expands angle between two intersecting rib tape, is intersected Rib tape angle expand, can make geotechnical grid parking space reduce, then in geotechnical grid material produce squeezing action, increase Plus interlocking, snap-in force between geotechnical grid and filler.
2nd, limiting tooth can play position-limiting action, increase and the interlocking effect of filler to filler.
3rd, when stressor layer is excessive on the soil body, sawtooth meeting Bending And Toppling plays a part of compensator or trimmer pressure, due to sawtooth and saw It is at regular intervals between tooth, so pressure will not mutually be covered.

Embodiment
For the technical characterstic for illustrating this programme can be understood, below by embodiment, this programme is illustrated.
As shown in figure 1, the utility model includes polylith rib tape 1, the adjacent rib tape 1, which is separated by, to be cross-linked into geotechnique Cell compartment, described 1 connected mode of rib tape is that bolt 2 is connected.The junction of rib tape 1 is provided with arc elastic steel plate 3, the arc The recess of spring steel plate 3 is towards the junction of rib tape 1.The arc elastic steel plate 3 across junction and two ends respectively with intersect two Individual rib tape 1 is connected.It is provided with reinforcement in the rib tape 1, the spring steel plate two ends are consolidated with the reinforcement that is provided with rib tape 1 respectively Connect.When geotechnical grid is in contracting overlapping state, the status of arc elastic steel plate 3 is as shown in Fig. 2 arc elastic steel plate now 3 are in diastole state, and rib tape 1 does not act power to it, when geotechnical grid is pulled into netted, intersecting two rib tape 1 it Between angle diminish, rib tape 1 is done work while angle diminishes to arc elastic steel plate 3, makes the recess of arc elastic steel plate 3 to remote From the expansion of the junction direction of rib tape 1, arc elastic steel plate 3 is in compressive state, and its particular state is as shown in Figure 3.It will need to fill out The material filled is inserted in geotechnical grid, and the arc elastic steel plate 3 in compressive state has the trend of a recovery diastole state, That is arc elastic steel plate 3 can overcome the pressure that rib tape 1 is produced to it, and rib tape 1 is done work, and make two intersecting rib tape 1 Between angle expand, the intersecting angle of rib tape 1 expands, and can reduce geotechnical grid parking space, then in geotechnical grid Material produces squeezing action, interlocking, snap-in force between increase geotechnical grid and filler.
The thickness of the arc elastic steel plate 3 is 2-5mm.
The surface of arc elastic steel plate 3 is connected with limiting tooth 4, and the length of the limiting tooth 4 differs.Filler inserts geotechnique After cell compartment, limiting tooth 4 can play position-limiting action, increase and the interlocking effect of filler to filler.
As prioritization scheme, as shown in figure 4, the upper end of the rib tape 1 is provided with sawtooth 5, the sawtooth 5 is discontinuous sawtooth 5, the spacing of sawtooth 5 is more than the width of sawtooth 5, when stressor layer is excessive on the soil body, the meeting Bending And Toppling of sawtooth 5, plays compensator or trimmer pressure Effect, due at regular intervals between sawtooth 5 and sawtooth 5, so pressure will not mutually be covered.The folder of the pointed projections of sawtooth 5 Angle is 60 °~120 °, and the angle can ensure sawtooth 5 by after soil pressure Bending And Toppling, and the larger area of sawtooth 5 can be wrapped preferably Wrap the soil body in cell compartment.
In order to ensure soil body density, humidity, temperature in each cell compartment etc., the rib tape 1 is provided with hole 6.
