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

Cement concrete interlocking concrete blocks mould is really a new sort of space kind, which was introduced to our country in the mid - 1980 - s, and on account of its exclusive superiority, so far in our nation, its application has been in the a number of terminal yard project, and has created fantastic social and financial impact.

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

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

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

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

3. Edge constraint can be a have to, whose role would be to limit lateral displacement of block around the road under the action of automobile loading, in an effort to ensure the interlock between the blocks. Germany, Britain, Australia, South Africa, the Netherlands, Japan and also other nations have made distinct varieties of researches on Interlocking plastic paver mold, as a way to discover the functions of interlocking block pavement. The basic conclusions are as follows:

1. The interlocking block plastic mold will not be independently bearing the carrying capacity.

2. Most researchers believe that the shapes of block have an impact on pavement efficiency that special-shaped pieces of interlocking performance are often greater than rectangular block, and performance of 4 edges of interlocking block is greater than that from the interlocking blocks on each sides on 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 larger.

5. The harm on the interlocking block paving is generally not on account of the fault block, but due to the block is washed towards the cut in to the base, and the way is accumulated to be permanent deformation (rutting)

6. interlocking moulds possess the very very good skid resistance efficiency. A big number of trials have promoted the successful application of interlocking block pavement and alter. Concrete block shape has been developed via imitating the brick to refined type tooth side from the rectangular block, and now it has achieved the development on the extensive reform on the special-shaped block today. Consistently trials improve and ideal the interlocking paving efficiency of program.
