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

Cement concrete interlocking concrete blocks mould is a new kind of space type, which was introduced to our nation in the mid - 1980 - s, and on account of its distinctive superiority, so far in our nation, its application has been in the multiple terminal yard project, and has made great social and economic effect.

Interlocking tiles mold structure mainly has 4 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 part of wearing layer, and plays a function of structure layer (overall diffusion load), and its block might be made into diverse shapes to create all sorts of design beautify the atmosphere.

1. The function of sand mat layer is leveling at the grass-roots level, and providing needed conditions for surface formed closely interlocking.

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

3. Edge constraint is actually a need to, whose function is to limit lateral displacement of block around the road beneath the action of vehicle loading, to be able to ensure the interlock among the blocks. Germany, Britain, Australia, South Africa, the Netherlands, Japan and other nations have made diverse kinds of researches on Interlocking plastic paver mold, as a way to find out the features of interlocking block pavement. The general conclusions are as follows:

1. The interlocking block plastic mold usually are not independently bearing the carrying capacity.

2. Most researchers believe that the shapes of block have an effect on pavement overall performance that special-shaped pieces of interlocking efficiency are usually much better than rectangular block, and efficiency of four edges of interlocking block is better than that from the interlocking blocks on each sides in the physique.

3. The interlocking block paving can withstand the massive deformation with no damage.

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

5. The damage in the interlocking block paving is normally not on account of the fault block, but on account of the block is washed for the cut in to the base, as well as the way is accumulated to become permanent deformation (rutting)

6. interlocking moulds possess the quite excellent skid resistance efficiency. A big quantity of trials have promoted the successful application of interlocking block pavement and modify. Concrete block shape has been developed through imitating the brick to refined kind tooth side of the rectangular block, and now it has accomplished the improvement of the complete reform of the special-shaped block today. Continuously trials boost and perfect the interlocking paving functionality of technique.
