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



Cement concrete interlocking concrete blocks mould can be a new form of space type, which was introduced to our nation in the mid - 1980 - s, and because of its distinctive superiority, so far in our country, its application has been in the numerous terminal yard project, and has produced fantastic social and economic impact.
Interlocking tiles mold structure mainly has four levels: interlocking block layer, sand layer, base and subgrade.
Interlocking block layer is different from other layers of pavement structure, which not merely plays a function of wearing layer, and plays a function of structure layer (general diffusion load), and its block could be produced into distinct shapes to create all sorts of design beautify the atmosphere.
1. The role of sand mat layer is leveling at the grass-roots level, and offering necessary circumstances for surface formed closely interlocking.
2. The base and subgrade with ordinary asphalt pavement is almost no distinction.
3. Edge constraint is a need to, whose function would be to limit lateral displacement of block around the road under the action of vehicle loading, as a way to guarantee the interlock among the blocks. Germany, Britain, Australia, South Africa, the Netherlands, Japan and also other countries have produced various forms of researches on Interlocking plastic paver mold, to be able to discover the features of interlocking block pavement. The general 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 overall performance that special-shaped pieces of interlocking performance are often much better than rectangular block, and efficiency of four edges of interlocking block is greater than that in the interlocking blocks on each sides in the body.
3. The interlocking block paving can withstand the huge deformation with no damage.
4. Compared with asphalt pavement chain block pavement rebound deflection is bigger.
5. The damage from the interlocking block paving is usually not because of the fault block, but due to the block is washed to the reduce in to the base, and also the way is accumulated to be permanent deformation (rutting)
6. interlocking moulds have the extremely excellent skid resistance efficiency. A sizable variety of trials have promoted the productive application of interlocking block pavement and change. Concrete block shape has been created via imitating the brick to refined kind tooth side from the rectangular block, and now it has accomplished the development of the complete reform from the special-shaped block these days. Consistently trials improve and perfect the interlocking paving functionality of system.
