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

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

Interlocking tiles mold structure primarily 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 function of structure layer (overall diffusion load), and its block can be created into diverse shapes to create all sorts of design and style beautify the atmosphere.

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

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

3. Edge constraint is a must, whose role is always to limit lateral displacement of block around the road under the action of car loading, to be able to make sure the interlock in between the blocks. Germany, Britain, Australia, South Africa, the Netherlands, Japan along with other nations have created distinct types of researches on Interlocking plastic paver mold, in an effort to discover 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 think that the shapes of block have an effect on pavement efficiency that special-shaped pieces of interlocking functionality are usually far better than rectangular block, and overall performance of 4 edges of interlocking block is much better than that in the interlocking blocks on each sides on the body.

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 in the interlocking block paving is generally not on account of the fault block, but as a result of the block is washed for the reduce in to the base, along with the way is accumulated to become permanent deformation (rutting)

6. interlocking moulds have the quite very good skid resistance functionality. A large quantity of trials have promoted the productive application of interlocking block pavement and adjust. Concrete block shape has been created by means of imitating the brick to refined sort tooth side on the rectangular block, and now it has achieved the development of the comprehensive reform in the special-shaped block right now. Constantly trials boost and best the interlocking paving overall performance of technique.
