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

Cement concrete interlocking concrete blocks mould can be a new form of space form, which was introduced to our country inside the mid - 1980 - s, and because of its unique superiority, so far in our country, its application has been within the numerous terminal yard project, and has produced fantastic social and economic effect.

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

Interlocking block layer is distinct from other layers of pavement structure, which not just plays a role of wearing layer, and plays a role of structure layer (general diffusion load), and its block could be made into different shapes to make all sorts of design beautify the atmosphere.

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

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

3. Edge constraint can be a should, whose role would be to limit lateral displacement of block around the road beneath the action of auto loading, in an effort to ensure the interlock between the blocks. Germany, Britain, Australia, South Africa, the Netherlands, Japan along with other countries have produced various forms of researches on Interlocking plastic paver mold, in order to find out 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 overall performance that special-shaped pieces of interlocking functionality are often far better than rectangular block, and performance of four edges of interlocking block is better than that in the interlocking blocks on both 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 bigger.

5. The harm from the interlocking block paving is usually not on account of the fault block, but due to the block is washed towards the reduce into the base, and also the way is accumulated to become permanent deformation (rutting)

6. interlocking moulds possess the quite excellent skid resistance overall performance. A sizable number of trials have promoted the successful application of interlocking block pavement and alter. Concrete block shape has been created by way of imitating the brick to refined type tooth side on the rectangular block, and now it has accomplished the development of the extensive reform in the special-shaped block these days. Constantly trials boost and excellent the interlocking paving overall performance of method.
