Abstract
The utility model discloses a combined earthwork grid which comprises grid rib belts laid out vertically and horizontally, wherein the rib belts are connected with each other by a cross-shaped fixed locking catch; one of two sections corresponding to the locking catch is provided with locking teeth, and the other section is provided with a locking hole which is matched with the locking teeth; rib belt nodes which are crossed vertically and horizontally are arranged at the middle part of the locking catch directly, and the rib belts are fixedly connected with each other by the method that the locking teeth and the corresponding locking hole are interlocked; the locking teeth are pawls for the firm of locking; insection for increasing friction force is arranged on a center plane of the locking catch, wherein the center plane is in a rectangle, a circle or a rhombus. The utility model without the restriction of the roll length and the breadth can carry out combination optionally in the field without special equipment; the utility model has the advantages of definite toughness, high strength, convenient production and transportation, etc. The utility model solves the overlength problem of broad earthwork grid in the processes of production and transportation.
Description
Technical field
The utility model relates to a kind of combined type geotechnique grid, belongs to civil engineering component technology field.
Background technology
In the process of construction of engineerings such as roadbed, dykes and dams, bank protection reinforced retaining wall, soft foundation, accident such as collapse owing to geological structure and soil layer reason, may appear caving in, ftractures, comes down, stride.For guaranteeing workmanship, take usually soil body reinforcement, promptly adopt geo-grid etc. to the soil body reinforce, reinforcement, make it remain an integral body and prevent soil body lateral displacement.In the prior art, geo-grid adopts one-shot forming or Combination Welding to reticulate cell structure by rib band (polyethylene wraps that steel wire is made or makes for polypropylene).The problem that one-time formed geo-grid exists is: can not fully stretch, volume length and fabric width all are restricted, because the overlength transportation is limited; Easy fracture when backfill rolls; Overlapping the slot is many during laying, and consumption worker consumptive material has increased construction cost; And the problem that the Combination Welding structure exists is, welding needs special equipment, can not realize field Welding; And there are problems such as solder joint is not firm, easy sealing-off.
The utility model content
At the above deficiency that above-mentioned two class geo-grid exist, the purpose of this utility model is to provide a kind of combination arbitrarily at the construction field (site) as required, not only combined and instant, rapid, and tensile strength height, the combined type geotechnique grid that node is firm.
The technical solution of the utility model is achieved in that combined type geotechnique grid, comprises the grid rib band of arranging in length and breadth, and grid rib band is linked by criss-cross pin and connects; One section is provided with the locking tooth in relative two sections of snap close, and another section is provided with and locks the lockhole that tooth cooperates; The rib band node of Jiao Chaing directly places the snap close middle part in length and breadth, and is by the lockhole interlocking of locking tooth and correspondence that the rib band is affixed.
It is firm in order to lock further improving, and described locking tooth is a pawl; For the median plane of the intensity snap close that increases snap close can be designed to rectangle, circle or rhombus, which is provided with to increase the groove of friction.
Compared to existing technology, the utlity model has following advantage:
1, geo-grid of the present utility model, its volume is long and fabric width is unrestricted, can make up arbitrarily at the scene, does not need special equipment;
2, during stationary grizzly, with the rib band in length and breadth the node of crisscross insert criss-cross fixedly snap close, by locking tooth and corresponding lockhole interlocking that the rib band is affixed, have combined and instant, characteristics rapidly;
3, because snap close adopts polypropylene or poly barb interlocking structure, connected node is firm, also has certain toughness, the tensile strength height;
4, produce, transportation is convenient, solved the wide cut geo-grid produce and transportation in the overlength problem.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a pin buckle structure schematic diagram.
The specific embodiment
As shown in Figure 1, combined type of the present utility model geotechnique grid, by rib band 1 be connected snap close 2 and combine.Its middle rib band 1 is a prior art, can be that polyethylene wraps that steel wire is made or makes for polypropylene.Rib band 1 intersects in length and breadth and constitutes the geo-grid body, and its crossover node place is fixing by connecting snap close 2.
Embodiment 1: connect snap close referring to Fig. 2, it is cross, one section is provided with locking tooth 3 in relative two sections, the termination of another section is provided with and locks the lockhole 4 that tooth cooperates, the rib band of Jiao Chaing directly places the middle part that connects snap close in length and breadth, because lockhole 4 interlockings of locking tooth 3 and correspondence are affixed with the rib band that intersects.
Embodiment 2: referring to Fig. 1 and Fig. 2, the locking tooth 3 that connects snap close 2 as different from Example 1 is pawl, and such locking effect is better.
Embodiment 3: on the basis of embodiment 1 and embodiment 2, for strengthen to connect snap close 2 the center intensity face can send out meter diamondwise, square, circle, rectangle etc. (shown in each row among Fig. 1, in fact adopt any to get final product), which is provided with groove to increase friction, skid on preventing.
The utility model is easy to use, only needs the crossover node of rib band is put on the connection snap close, relative locking tooth is inserted the lockhole tension get final product.The utility model can be as required combination arbitrarily at the construction field (site), not only combined and instant, rapidly, and tensile strength height, node are firm.
The utility model is not limited to described embodiment, and every employing cross connects the combined type geotechnique grid of snap close or equivalent structure formation, all falls into the scope of the utility model protection.
Claims (3)
