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

Cement concrete interlocking concrete blocks mould can be a new kind of space form, which was introduced to our nation in the mid - 1980 - s, and on account of its special superiority, so far in our country, its application has been in the several terminal yard project, and has created wonderful 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 only plays a part 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 beautify the environment.

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

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

3. Edge constraint is really a should, whose role is usually to limit lateral displacement of block on the road under the action of automobile loading, in an effort to ensure the interlock amongst the blocks. Germany, Britain, Australia, South Africa, the Netherlands, Japan as well as other countries have produced diverse types of researches on Interlocking plastic paver mold, in an effort to learn the characteristics of interlocking block pavement. The general conclusions are as follows:

1. The interlocking block plastic mold aren't independently bearing the carrying capacity.

2. Most researchers think that the shapes of block have an effect on pavement efficiency that special-shaped pieces of interlocking performance are usually far better than rectangular block, and efficiency of four edges of interlocking block is better than that of the interlocking blocks on each sides in the body.

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

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

5. The damage from the interlocking block paving is generally not because of the fault block, but because of the block is washed to the cut into the base, as well as the way is accumulated to be permanent deformation (rutting)

6. interlocking moulds have the quite great skid resistance overall performance. A big quantity of trials have promoted the profitable application of interlocking block pavement and alter. Concrete block shape has been created by way of imitating the brick to refined kind tooth side from the rectangular block, and now it has accomplished the improvement on the extensive reform in the special-shaped block nowadays. Continuously trials improve and ideal the interlocking paving efficiency of program.
