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

Cement concrete interlocking concrete blocks mould is actually a new type of space type, which was introduced to our nation in the mid - 1980 - s, and as a result of its unique superiority, so far in our nation, its application has been inside the a number of terminal yard project, and has made excellent social and financial impact.

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

Interlocking block layer is various from other layers of pavement structure, which not just plays a role of wearing layer, and plays a role of structure layer (all round diffusion load), and its block may be made into distinct shapes to create all sorts of design and style beautify the environment.

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

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

3. Edge constraint is really a should, whose role is usually to limit lateral displacement of block around the road under the action of car loading, to be able to guarantee the interlock in between the blocks. Germany, Britain, Australia, South Africa, the Netherlands, Japan along with other nations have made various kinds of researches on Interlocking plastic paver mold, in order 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 think that the shapes of block have an effect on pavement performance that special-shaped pieces of interlocking efficiency are often greater than rectangular block, and overall performance of 4 edges of interlocking block is greater than that from the interlocking blocks on each sides on 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 in the interlocking block paving is normally not due to the fault block, but as a result of the block is washed for the cut into the base, and also the way is accumulated to become permanent deformation (rutting)

6. interlocking moulds possess the very good skid resistance overall performance. A sizable variety of trials have promoted the productive application of interlocking block pavement and alter. Concrete block shape has been created via imitating the brick to refined sort tooth side in the rectangular block, and now it has achieved the development of the extensive reform from the special-shaped block these days. Continuously trials enhance and ideal the interlocking paving functionality of method.
