The technical problem that the utility model will solve provide a kind of simple in structure, assembling is easy, reliability is higher and the spliced chinampa of environmental protection.

In order to solve the problems of the technologies described above; The utility model provides a kind of spliced chinampa; It comprises the lawn layer of setting up and down and the base plate of single injection-molded, is distributed with a plurality of installing holes on the base plate, and the lawn layer is fixed on the base plate through the bail that a plurality of and said installing hole cooperates; Said bail comprises: the head of a nail and nail bar; Be characterized in: the central portion of said nail bar has and is suitable for and the friction tight elasticity flared of said installing hole; This elasticity flared is provided with the rhombus groove, and the angle a pair of far away of this rhombus groove is along the axial distribution of nail bar; Or this elasticity flared is provided with elliptical slot, and the major axis of this elliptical slot is along the axial distribution of nail bar.

Rhombus groove or elliptical slot are suitable for making said elasticity flared to have elasticity, are beneficial to the installing hole that makes on elasticity flared and the said base plate and assemble repeatedly, dismantle, and have its long application life.

When in a single day bail broke away from said installing hole and be hidden in the layer of lawn, for eliminating the potential safety hazard to human body (especially football player), the top of said bail was arc surface.

The degree of depth of said rhombus groove or elliptical slot is for 0.3-0.7 times of the nail shank diameter, so that said elasticity flared has more suitable elasticity.Rhombus groove or elliptical slot have bigger elasticity with respect to through hole, are beneficial to the installing hole that makes on said elasticity flared and the said base plate and keep tight fit for a long time; After bail was extracted, the shape of said elasticity flared realized resetting easily.

Said bail single injection-molded has characteristics convenient for production, with low cost.

The a pair of neighboring edge of base plate is provided with a plurality of contiguous blocks, and each contiguous block is provided with spliced eye; Another of base plate to neighboring edge be distributed be used for another base plate on the plug-in unit post that cooperates of each spliced eye plug-in unit.

Further, be to reduce weight and cost, be beneficial to permeablely simultaneously, be distributed with hollow-out parts on the said base plate.

As the embodiment of optimizing; Said contiguous block stretches out from the edge bottom of said base plate, said plug-in unit post from the edge bottom of said base plate to extending below, with when two base plates splicings; The upper surface of these two base plates flushes, and then has guaranteed the whole planeness of lawn layer.

The technique scheme of the utility model is compared prior art and had the following advantages: the elasticity flared of the nail bar central authorities that (1) the utility model adopts is provided with rhombus or elliptical slot; It is suitable for making said elasticity flared to have elasticity, and this elasticity is suitable for the long period maintenance; After bail was extracted, the shape of said elasticity flared realized resetting easily, was suitable for repeated disassembled and assembled, had guaranteed its long application life; Adopt the design of elasticity flared on the bail,, and have the characteristics of installation, convenient disassembly with respect to the design scheme that adopts lancination.In addition, bail integral body is less, and the area that the head of a nail of bail takies on the layer of lawn is also less, can guarantee the fidelity of lawn layer; (2) the spliced chinampa of the utility model is fixed on the lawn layer on the base plate through bail, and adjacent base plate is suitable for realizing snapping through said spliced eye and plug-in unit post each other, lays to realize large tracts of land, and is easy and simple to handle, made things convenient for use.Whole process need not glue, safety and environmental protection.
