Abstract
The invention provides an injection molding ring connection grid, relating to a geotechnical grid. The grid is formed by arranging longitudinal belts and latitudinal belts in a mesh state; cross junctions of the longitudinal belts and the latitudinal belts are positioned by locking notches; the locking notches are connected with the longitudinal belts and the latitudinal belts of the grid into an integral structure; every locking notch is of a one-step injection-molded circular ring shape; the periphery of each locking notch circular ring fixes the cross junctions of the longitudinal belts and the latitudinal belts of the grid; and the longitudinal belts and the latitudinal belts in the middle of each locking notch circular ring are exposed. The structure improves the fixing force and peeling force of the grid; the longitudinal and latitudinal belts all play a role in that: the slip resistance of soil plates is increased under external force or during settlement, and the force of resisting slip is not concentrated on injection molding ring connection. Therefore, the functions of the grid on resisting settlement and soil plate slip are reinforced.
Description
Technical field
The present invention relates in the engineering constructions such as a kind of highway, municipal administration the soft base base be carried out the geo-grid of strength enhancing, refer in particular to a kind of injection molding circle adapting grille.
Background technology
Chinese patent 200620074598.X discloses " the integrated geo-grid of treatment of soft foundation ", form by vertical, latticed the arranging of cross rib band, vertically, the crossbar contact of cross rib band is located by fore shaft, described fore shaft and grid are vertical, the injection moulding of cross rib band connects to overall structure, the fore shaft of one owing property injection molded, the handing-over fixed point of locking warp-wise band and broadwise band is at trough of belt place all around, and fixation is not played on two planes up and down, connection when being injection moulding and appearance looks elegant effect; Snap close contact grid is in the engineering construction process, the longitude and latitude interface point is higher than grid, be empty in the middle of the snap close wherein, landfill layer and grid connect and melt on snap close, when the landfill layer is laid in the construction of compacting, make snap close distortion, displacement and destruction easily, just be trapped in (the landfill layer mostly adopts soil, rubble and lime-ash) under the landfill layer, be difficult to observe directly; Snap close contact grid especially in soft base, is subjected to the factor of sedimentation in engineering, snap close and packing course to connect the frictional force of melting face little, anti-skid force concentrates on the snap close, is difficult to guarantee crack phenomenon to occur because of local sedimentation causes the slippage of soil plate.
Summary of the invention
The present invention is just in order to overcome above-mentioned deficiency, a kind of have very strong bed knife, the grid of peeling force are provided, be when mainly changing that fore shaft is the disposable circle shape that is injection molded into, by stationary grizzly longitude and latitude band interface point around the circle, longitude and latitude band in the middle of the circle is exposed up and down, and the direct embedding of landfill layer is pressed on the middle longitude and latitude band, and the resistance of soil plate slippage increases when being subjected to external force or sedimentation, the power that antiskid moves does not concentrate on the injection molding circle adapting, and the longitude and latitude band has all played effect.Really making geo-grid play the effect of anti-sedimentation, the slippage of anti-soil plate in engineering, is the reinforced structure in the immobilizing foundation.Specifically implement like this: injection molding circle adapting grille, by forming through band, latticed the arranging of latitude band, crossbar contact through band, latitude band is located by fore shaft, described fore shaft and grid connect to overall structure through band, the injection moulding of latitude band, it is characterized in that fore shaft is the disposable circle shape that is injection molded into, be the fore shaft circle around stationary grizzly longitude and latitude band crossbar contact, the longitude and latitude band in the middle of the fore shaft circle is exposed shape.
Grid longitude and latitude band of the present invention is a plastic tape, snap close also be adopt polyethylene or polypropylene through the plasticizing back of heating at the disposable fixedly longitude and latitude contact of circle that is injected into of the longitude and latitude junction of grid, make its composition mesh grille.
The present invention changes the planform of snap close, improved bed knife, the peeling force of grid, the resistance of soil plate slippage increases when being subjected to external force or sedimentation, and the power that antiskid moves does not concentrate on the injection molding circle adapting, the longitude and latitude band has all played effect, and the effect of its anti-sedimentation, the slippage of anti-soil plate is strengthened.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
The specific embodiment
Injection molding circle adapting grille, by plastics through be with 1, latitude band 2 latticed arranging form, through with 1, the crossbar contact of latitude band 2 is by fore shaft 3 location, this fore shaft 3 and grid through be with 1,2 injection mouldings of latitude band connect to overall structure, fore shaft 3 is the disposable circle shape that is injection molded into after the plasticizing of heating for polyethylene or polypropylene, be fore shaft 3 circles around stationary grizzly longitude and latitude band crossbar contact, the longitude and latitude band in the middle of the fore shaft circle is exposed shape.
Claims (3)
1. injection molding circle adapting grille, by forming through band, latticed the arranging of latitude band, crossbar contact through band, latitude band is located by fore shaft, described fore shaft and grid connect to overall structure through band, the injection moulding of latitude band, it is characterized in that fore shaft is the disposable circle shape that is injection molded into, be the fore shaft circle around stationary grizzly longitude and latitude band crossbar contact, the longitude and latitude band in the middle of the fore shaft circle is exposed shape.
2. injection molding circle adapting grille according to claim 1, the longitude and latitude band that it is characterized in that grid is a plastic tape.
3. injection molding circle adapting grille according to claim 1 is characterized in that circle shape snap close is at the disposable circle shape fore shaft that is injected into of the longitude and latitude junction of grid after polyethylene or polypropylene plastify through heating.
