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

Cement concrete interlocking concrete blocks mould is really a new kind of space kind, which was introduced to our country inside the mid - 1980 - s, and because of its distinctive superiority, so far in our nation, its application has been in the several 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 different from other layers of pavement structure, which not merely plays a role of wearing layer, and plays a role of structure layer (all round diffusion load), and its block may be made into different shapes to create all sorts of design beautify the atmosphere.

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

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

3. Edge constraint can be a should, whose part is always to limit lateral displacement of block on the road beneath the action of car loading, in an effort to ensure the interlock between the blocks. Germany, Britain, Australia, South Africa, the Netherlands, Japan and other countries have made various kinds of researches on Interlocking plastic paver mold, to be able to learn the attributes of interlocking block pavement. The common conclusions are as follows:

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

2. Most researchers believe that the shapes of block have an impact on pavement functionality that special-shaped pieces of interlocking overall performance are often much better than rectangular block, and overall performance of four edges of interlocking block is greater than that of the interlocking blocks on both sides on the physique.

3. The interlocking block paving can withstand the massive deformation with no harm.

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

5. The damage on the interlocking block paving is generally not on account of the fault block, but on account of the block is washed towards the cut into the base, and also the way is accumulated to be permanent deformation (rutting)

6. interlocking moulds possess the quite good skid resistance performance. A large number of trials have promoted the profitable application of interlocking block pavement and modify. Concrete block shape has been created by means of imitating the brick to refined kind tooth side from the rectangular block, and now it has achieved the improvement in the comprehensive reform on the special-shaped block right now. Continuously trials boost and perfect the interlocking paving efficiency of method.
