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

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

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

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

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

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

3. Edge constraint can be a should, whose part would be to limit lateral displacement of block around the road below the action of automobile loading, in an effort to make certain the interlock in between the blocks. Germany, Britain, Australia, South Africa, the Netherlands, Japan as well as other countries have produced different forms of researches on Interlocking plastic paver mold, as a way to discover the functions 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 think that the shapes of block have an impact on pavement performance that special-shaped pieces of interlocking efficiency are often better than rectangular block, and overall performance of 4 edges of interlocking block is greater than that of the interlocking blocks on both sides of the physique.

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

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

5. The harm from the interlocking block paving is generally not on account of the fault block, but due to the block is washed for the reduce into the base, as well as the way is accumulated to become permanent deformation (rutting)

6. interlocking moulds possess the extremely good skid resistance overall performance. A sizable variety of trials have promoted the successful application of interlocking block pavement and modify. Concrete block shape has been created via imitating the brick to refined kind tooth side on the rectangular block, and now it has achieved the development of the comprehensive reform in the special-shaped block right now. Continually trials boost and excellent the interlocking paving performance of program.
