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

Cement concrete interlocking concrete blocks mould is a new type of space kind, which was introduced to our nation in the mid - 1980 - s, and on account of its special superiority, so far in our nation, its application has been within the several terminal yard project, and has produced fantastic social and financial effect.

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

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

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

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

3. Edge constraint is actually a must, whose role would be to limit lateral displacement of block around the road below the action of automobile loading, to be able to make sure the interlock among the blocks. Germany, Britain, Australia, South Africa, the Netherlands, Japan and other countries have made diverse varieties of researches on Interlocking plastic paver mold, as a way to find out the attributes of interlocking block pavement. The general conclusions are as follows:

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

2. Most researchers believe that the shapes of block have an effect on pavement performance that special-shaped pieces of interlocking efficiency are often much better than rectangular block, and functionality of four 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 huge deformation with no damage.

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

5. The damage from the interlocking block paving is generally not due to the fault block, but because of the block is washed for the reduce into the base, along with the way is accumulated to be permanent deformation (rutting)

6. interlocking moulds have the really great skid resistance overall performance. A big number of trials have promoted the effective application of interlocking block pavement and alter. Concrete block shape has been developed through imitating the brick to refined kind tooth side from the rectangular block, and now it has accomplished the improvement on the comprehensive reform in the special-shaped block right now. Continuously trials boost and best the interlocking paving performance of method.
