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

Cement concrete interlocking concrete blocks mould can be a new type of space kind, which was introduced to our country within the mid - 1980 - s, and because of its unique superiority, so far in our nation, its application has been inside the multiple terminal yard project, and has produced excellent social and financial impact.

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

Interlocking block layer is different from other layers of pavement structure, which not simply plays a part of wearing layer, and plays a role of structure layer (overall diffusion load), and its block can be made into different shapes to create all sorts of design and style beautify the environment.

1. The function of sand mat layer is leveling in the grass-roots level, and supplying essential situations for surface formed closely interlocking.

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

3. Edge constraint can be a need to, whose part is to limit lateral displacement of block on the road below the action of car loading, in order to make sure the interlock between the blocks. Germany, Britain, Australia, South Africa, the Netherlands, Japan as well as other nations have made various kinds of researches on Interlocking plastic paver mold, in order to find out the features of interlocking block pavement. The basic conclusions are as follows:

1. The interlocking block plastic mold are not 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 functionality are often better than rectangular block, and overall performance of four edges of interlocking block is far better than that on the interlocking blocks on each sides of the body.

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

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

5. The harm from the interlocking block paving is normally not due to the fault block, but due to the block is washed for the cut in to the base, as well as the way is accumulated to be permanent deformation (rutting)

6. interlocking moulds possess the very excellent skid resistance performance. A sizable variety of trials have promoted the successful application of interlocking block pavement and modify. Concrete block shape has been created through imitating the brick to refined variety tooth side from the rectangular block, and now it has accomplished the improvement on the extensive reform from the special-shaped block nowadays. Continuously trials increase and best the interlocking paving overall performance of method.
