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

Cement concrete interlocking concrete blocks mould can be a new type of space form, which was introduced to our nation within the mid - 1980 - s, and due to its exclusive superiority, so far in our nation, its application has been within the numerous terminal yard project, and has made excellent social and economic impact.

Interlocking tiles mold structure mostly has 4 levels: interlocking block layer, sand layer, base and subgrade.

Interlocking block layer is different from other layers of pavement structure, which not just plays a role of wearing layer, and plays a part of structure layer (overall diffusion load), and its block may be produced into distinct shapes to make all sorts of design and style beautify the atmosphere.

1. The part of sand mat layer is leveling in the grass-roots level, and delivering necessary conditions for surface formed closely interlocking.

2. The base and subgrade with ordinary asphalt pavement is practically no distinction.

3. Edge constraint is actually a have to, whose role would be to limit lateral displacement of block on the road under the action of vehicle loading, in order to guarantee the interlock among the blocks. Germany, Britain, Australia, South Africa, the Netherlands, Japan and also other countries have made different kinds of researches on Interlocking plastic paver mold, in an effort to learn the attributes of interlocking block pavement. The basic conclusions are as follows:

1. The interlocking block plastic mold usually are not independently bearing the carrying capacity.

2. Most researchers think that the shapes of block have an effect on pavement performance that special-shaped pieces of interlocking overall performance are often much better than rectangular block, and overall performance of 4 edges of interlocking block is far better than that on the interlocking blocks on both sides of the body.

3. The interlocking block paving can withstand the big deformation with no damage.

4. Compared with asphalt pavement chain block pavement rebound deflection is bigger.

5. The damage on the interlocking block paving is usually not due to the fault block, but because of the block is washed towards the reduce into the base, as well as the way is accumulated to become permanent deformation (rutting)

6. interlocking moulds have the quite good skid resistance functionality. A big number of trials have promoted the profitable application of interlocking block pavement and adjust. Concrete block shape has been developed by means of imitating the brick to refined type tooth side from the rectangular block, and now it has accomplished the improvement of the extensive reform on the special-shaped block today. Continually trials boost and perfect the interlocking paving overall performance of technique.
