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

Cement concrete interlocking concrete blocks mould can be a new type of space kind, which was introduced to our country in the mid - 1980 - s, and as a result of its unique superiority, so far in our nation, its application has been inside the a number of terminal yard project, and has created great social and financial effect.

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 simply plays a role of wearing layer, and plays a role of structure layer (all round diffusion load), and its block might be made into diverse shapes to create all sorts of design beautify the atmosphere.

1. The function of sand mat layer is leveling in the grass-roots level, and supplying essential situations for surface formed closely interlocking.

2. The base and subgrade with ordinary asphalt pavement is nearly no difference.

3. Edge constraint can be a need to, whose function is usually to limit lateral displacement of block on the road beneath the action of car loading, in an effort to make sure the interlock among the blocks. Germany, Britain, Australia, South Africa, the Netherlands, Japan as well as other countries have produced various kinds of researches on Interlocking plastic paver mold, to be able to learn the attributes of interlocking block pavement. The basic conclusions are as follows:

1. The interlocking block plastic mold will not be independently bearing the carrying capacity.

2. Most researchers think that the shapes of block have an impact on pavement functionality that special-shaped pieces of interlocking functionality are usually greater than rectangular block, and functionality of four edges of interlocking block is far better than that from the interlocking blocks on each sides from the physique.

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 damage in the interlocking block paving is usually not due to the fault block, but on account of the block is washed towards the cut into the base, as well as the way is accumulated to be permanent deformation (rutting)

6. interlocking moulds have the extremely good skid resistance overall performance. A large number of trials have promoted the effective application of interlocking block pavement and modify. Concrete block shape has been created by way of imitating the brick to refined variety tooth side from the rectangular block, and now it has achieved the development on the complete reform in the special-shaped block today. Continuously trials enhance and ideal the interlocking paving performance of system.
