Abstract

The utility model relates to a reinforced geocell which comprises grid belts produced by polymer material or grid belts wrapped with reinforced material, the grid belts are laid out with upright surface, nodes are formed by spacing and dislocation connection between the grid belts, and net shaped cells with three-dimension stereo structure are formed through mechanical connection or adhesion and welding. The grid belts can be broadband or narrowband groups with water discharging holes, and techniques such as buckling, locking, riveting, blocking, sticking and welding are used on the nodes to bond the grid belts into the geocell with stereo three dimensional structure, and to furl into bundles to make the storage and transportation convenient, the geocell is extended to make the construction convenient, the tensile strength is high, the elongation ratio is low, and the weight is light, clay can pass the lock and occlude in an embedded manner in three directions of the longitudinal, the lateral and the vertical, and the mutual function with the clay is very good. The technique and the device are simple, the production cost is low, storage, transportation and use are all convenient, and the life is long, thus can be widely used in foundation reinforcement and reinforced retaining wall, and used in projects such as the reinforced bridge abutment to reduce sediment, the reinforced side slope to preserve soil and plant grass, and the desert to accumulate sand to build road, and has better technical and economic benefits compared with plane grid.

Description

The reinforcement geotechnical grid

Technical field

The utility model relates to the reinforcement material in the modern earthwork engineering, is to be combined into ribbon with muscle material (comprising wire and nonmetal wire) and macromolecular material, again through mechanical connection or glue, be welded to form the stereoscopic three-dimensional grid.In order to strengthen the bearing capacity of ground, reduce bulk settling, overcome differential settlement, strengthen soil body globality, be specially adapted to the desert and build the road, it is firm integral body that layering gathers loose sand.Be widely used in the engineerings such as reinforced retaining wall, embankment, abutment, embankment, airport, harbour, railway.

Technical background

The geotechnical grid that uses is that the broadband is sticking again through being extruded into, weldering forms for plastics now, stressed relatively poor, elongation per unit length big (10-15%), creep are big, the general Slope Treatment that only is used for road, the slope is slow then can, when the slope was steep, node (welding) had the breakage that comes off in various degree, and difficulty reaches the effect of bank protection and ecological afforestation.And handling soft base, abutments etc. often pulling force greatly but are out of shape big inadequately.Have only to increase the needs that the number of plies satisfies structure are set, must increase worker, material, promptly increase cost.

The content of invention

The purpose of this utility model is to provide a kind of reinforcement geotechnical grid, its range of application is wider, satisfy engineering and be subjected to the force intensity height, the geotechnical grid formed of grid band particularly, has effect vertical and wear the lock build-in in length and breadth to filler, be subjected to Z-TEK good, modification is little, saving of labor, material-saving, save time, and improves its security reliability.

The purpose of this utility model is to realize by such technical scheme: promptly a kind of reinforcement geotechnical grid, the grid band of making by macromolecular material or wrap up in the grid band that the muscle material that tensile strength is big, elongation per unit length is little is arranged again, grid band facade is arranged, spacing dislocation connects into node between the grid band, and by mechanical connection or glue, be welded to form the netted lattice chamber of three-dimensional, stereochemical structure.

Description of drawings

Said structure of the present utility model is further specified by the embodiment that accompanying drawing provides.

The utility model has following accompanying drawing:

Accompanying drawing 1 is that the structure of the utility model embodiment 1 is launched schematic diagram;

Accompanying drawing 2 is the enlarged diagram at embodiment 1 node place;

Accompanying drawing 3 is the structural representation of the anchorage clip of embodiment 1 node;

Accompanying drawing 5 is that the structure of the utility model embodiment 2 is launched schematic diagram;

Accompanying drawing 6 is embodiment 2 node place structural representations;

Accompanying drawing 7 is the structural representation of embodiment 2 arrowband groups.

Referring to accompanying drawing, 1-broadband, 2-clip, 3-clasp, 4-latch closure hole, 5-spilled water hole, 6-arrowband, 7-latch among the figure.

The specific embodiment

Embodiment 1 is referring to accompanying drawing 1-4, and the geotechnical grid among Fig. 1 is to be arranged by reinforcement broadband (1) (5-30cm is wide) facade, and the spacing dislocation connects into node between the two grid bands, and by the fixing netted lattice chamber of forming three-dimensional, stereochemical structure of anchorage clip.Wherein: grid band (1) is gone up has clasp hole (4) by spacing, and anchorage clip is made of clip (2) and clasp (3), the clasp hole of the two grid bands alignment at the node place, and clasp is positioned at it, and clip is clipped in outside the two grid bands, and is fixed by clasp.The net of forming stereochemical structure is received Gansu Province and bundledly is convenient to accumulating, is launched into the lattice chamber and is beneficial to construction.The firm degree specific viscosity of node, welding height.Be used for the stressed big position of engineering, sticking, welding lattice chamber then is used for the not high position of force request.Can have spilled water hole (5) (the not sluicing water hole that is used for arid tracts such as desert) on the grid band.

Embodiment 2 is referring to accompanying drawing 5-7, and the facade of the geotechnical grid grid band among the figure is arranged in parallel into grid band group by reinforcement arrowband, at least two arrowbands (6) spacing, and is fixed by the grid band in the facade spacing; Spacing dislocation connects into node between the arrowband group, the node place by latch fix the netted lattice chamber of stereoscopic three-dimensional structure.Respectively there is the opposite anti-retreating hook of a direction at the two ends of latch, and two groups of arrowbands at node place intert mutually, and latch vertically is inserted in the inserting hole of arrowband group, and the anti-retreating hook at its two ends prevents that the arrowband from coming off.Latch is replaced in also available arrowband at the node place, fixes after bonding.

Also available PP, the PE band that stretches through extrusion molding replaces the reinforcement arrowband, forms the netted lattice of stereoscopic three-dimensional chamber with aforesaid way, and tensile strength is suitable, and just modification is big slightly, can choose for the engineering of different purposes.

The utility model is owing to described structure has the characteristics such as tensile strength height, percentage elongation be low, in light weight, Because being that the grid band is formed, earth can longitudinal and transverse, perpendicular three-dimensional be worn the interlock of lock build-in, with the interaction spy of earth Good. And Processes and apparatus is simple, and storage, transportation, use all make things convenient for, and the life-span is long, is widely used in ground Base is reinforced, reinforced retaining wall; The reinforcement abutment reduces sedimentation, prevents from jumping car; Reinforced slope soil conservation grass planting; With The poly-sand engineering such as build the road is compared with the plane grid in the desert, and three-dimensional lattice chamber has more good Technological Economy effect Benefit.
