interlocking moulds, an introduction to it and its layer of structure



Cement concrete interlocking concrete blocks mould is actually a new kind of space form, which was introduced to our nation in the mid - 1980 - s, and because of its unique superiority, so far in our country, its application has been in the numerous terminal yard project, and has produced fantastic social and economic effect.
Interlocking tiles mold structure mostly has four levels: interlocking block layer, sand layer, base and subgrade.
Interlocking block layer is diverse from other layers of pavement structure, which not merely plays a function of wearing layer, and plays a function of structure layer (overall diffusion load), and its block could be created into distinct shapes to create all sorts of design beautify the environment.
1. The part of sand mat layer is leveling at the grass-roots level, and supplying necessary conditions for surface formed closely interlocking.
2. The base and subgrade with ordinary asphalt pavement is nearly no difference.
3. Edge constraint is actually a have to, whose part is usually to limit lateral displacement of block on the road under the action of automobile loading, in an effort to ensure the interlock between the blocks. Germany, Britain, Australia, South Africa, the Netherlands, Japan as well as other nations have produced various kinds of researches on Interlocking plastic paver mold, in an effort to discover the attributes of interlocking block pavement. The common conclusions are as follows:
1. The interlocking block plastic mold are not independently bearing the carrying capacity.
2. Most researchers think that the shapes of block have an effect on pavement functionality that special-shaped pieces of interlocking performance are often much better than rectangular block, and functionality of four edges of interlocking block is much better than that on the interlocking blocks on each sides in the body.
3. The interlocking block paving can withstand the large deformation with no harm.
4. Compared with asphalt pavement chain block pavement rebound deflection is larger.
5. The harm in the interlocking block paving is normally not because of the fault block, but because of the block is washed for the cut into the base, as well as the way is accumulated to become permanent deformation (rutting)
6. interlocking moulds have the extremely very good skid resistance overall performance. A large variety of trials have promoted the effective application of interlocking block pavement and alter. Concrete block shape has been developed by means of imitating the brick to refined sort tooth side on the rectangular block, and now it has accomplished the improvement from the complete reform from the special-shaped block today. Continuously trials boost and best the interlocking paving performance of technique.
