Abstract
The invention discloses a high-strength geocell which comprises steel bars and plug-in elements, wherein an open slot is correspondingly formed in the junction of adjacent steel bars, the free ends of the plug-in elements respectively pass through the open slots on the two steel bars in sequence in a staggered manner to connect and weave the two steel bars together, and seal locking elements for preventing plug-in elements from coming out are connected with the free ends of the plug-in elements. The seal locking elements arranged on the plug-in elements can effectively prevent the plug-in elements from coming out during the fabrication, transportation and use processes of the geocell, so as to ensure the normal use of the geocell.
Description
Technical field
The present invention relates to a kind of geotechnical grid.
Background technology
Geotechnical grid is to process sheet material by macromolecular material, through process means, forms the space, netted lattice chamber of stereochemical structure; It is capable of expansion and contraction; Can contract during transportation gathers into folds, and opens during use and filling soil stone or concrete material again, constitutes the structure with powerful lateral limitation power and big rigidity.Common in order to reinforce the roadbed of Rail Highway, airport, harbour side slope protection are built engineering fields such as retaining wall.
At present, geotechnical grid has following several kinds:
1, the plastic sheet band is through the extrusion calendaring moulding, and is not stretched, forms with ultrasonic heat fusion welding node, and node strength has only 200N/cm, and very easily cracking causes the engineering failure.
2, the plastic sheet band stretched after, node has adopted the rivet mode, though the sheet material hot strength has improved, node strength does not still reach the hot strength of sheet material, so node remains weak link.
3, the plastic sheet band is through the extrusion calendaring moulding, and not stretched, the mode that adopts hole knockout to peg graft with single plug-in unit is formed by connecting, and this kind mode is unstretched because of sheet material, and molecules align does not have orientation, can damage band if stamp the hole, place's embrittlement along the hole.
4, publication number is that the Chinese utility model patent of CN201598629U discloses a kind of monolithic geotechnical grid; The characteristics of this geotechnical grid are that adopting double end plug-in unit grafting establishment to connect at the node place forms; Effectively solve the more weak problem of node intensity of three kinds of lattice chambers, front; Node and muscle band strength are mated preferably, brought into play the three-dimensional reinforcement effect of geotechnical grid to greatest extent, have result of use preferably.But production and use in reality have also exposed the following defective of above-mentioned geotechnical grid: 1, in goods manufacturing process, because inter process frequent changes operation position causes mounted plug-in unit dislocation, loosening, generation obscission.2, in goods carrying, entrucking, unload, in the transportation, plug-in unit also slides easily, obscission.3, in the goods work progress, after the expansion, at first select the insert aperture direction down, otherwise plug-in unit drops easily.
The caducous defective of above-mentioned plug-in unit has caused bigger puzzlement for the production and the use of product, causes very big hidden danger to workmanship.
Summary of the invention
The powerful geotechnical grid that the object of the invention provides a kind of plug-in unit can not come off with regard to the defective that is to above-mentioned prior art.
Its technical solution is following: powerful geotechnical grid; Comprise muscle band and plug-in unit; The node place correspondence of adjacent muscle band offers joint-cutting; The free end of plug-in unit is staggered successively respectively to be passed two joint-cuttings on the muscle band and pegs graft two muscle bands to connect and be woven to one, and the free end of said plug-in unit is connected with the sealing latch fitting that prevents that plug-in unit from deviating from.
Above-mentioned plug-in unit can be a kind of in J-shaped, U-shaped, the M shape.
Above-mentioned sealing latch fitting can be elasticity or flexible flake; Offer diameter on the said thin slice and be slightly less than the through hole of plug-in unit free end diameter; The plug-in unit free end radially offers annular slot, and above-mentioned thin slice is connected in the annular slot on the plug-in unit free end through the through hole on it.
Above-mentioned plug-in unit free end can be done camber, is beneficial to thin slice and snaps in.
Above-mentioned sealing latch fitting can be a rigid sheet, offers the through hole of somewhat larger in diameter in plug-in unit free end diameter on the rigid sheet, after rigid sheet is sleeved on the plug-in unit free end, through riveting or be bolted to the plug-in unit free end.
Above-mentioned thin slice can be various suitable materials such as plastics, metal.
When plug-in unit has a plurality of parallel free ends, when adopting U-shaped or M shape, above-mentioned thin slice can adopt a monolithic thin slice, and promptly each free end of corresponding plug-in unit is offered through hole on a bigger thin slice.Can further strengthen the globality of product like this, obtain better slip-off preventing effect.
Because plug-in unit of the present invention is provided with the sealing latch fitting of preventing deviating from, and can effectively prevent plug-in unit deviating from geotechnical grid making, transportation, use, guarantee the normal use of geotechnical grid.
Below in conjunction with accompanying drawing the present invention is further specified.
