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



Cement concrete interlocking concrete blocks mould is a new type of space type, which was introduced to our nation within the mid - 1980 - s, and due to its distinctive superiority, so far in our country, its application has been inside the multiple terminal yard project, and has created excellent social and financial impact.
Interlocking tiles mold structure mostly 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 role of structure layer (all round diffusion load), and its block might be produced into distinct shapes to make all sorts of design beautify the environment.
1. The role of sand mat layer is leveling at the grass-roots level, and supplying required circumstances for surface formed closely interlocking.
2. The base and subgrade with ordinary asphalt pavement is almost no distinction.
3. Edge constraint is a must, whose part is usually to limit lateral displacement of block around the road under the action of auto loading, in an effort to make sure the interlock between the blocks. Germany, Britain, Australia, South Africa, the Netherlands, Japan as well as other nations have produced diverse varieties of researches on Interlocking plastic paver mold, as a way to learn the functions of interlocking block pavement. The general conclusions are as follows:
1. The interlocking block plastic mold aren't independently bearing the carrying capacity.
2. Most researchers think that the shapes of block have an impact on pavement overall performance that special-shaped pieces of interlocking efficiency are often much better than rectangular block, and overall performance of 4 edges of interlocking block is far better than that from the interlocking blocks on both sides in the body.
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 from the interlocking block paving is generally not due to the fault block, but because of the block is washed to the cut in to the base, as well as the way is accumulated to be permanent deformation (rutting)
6. interlocking moulds have the extremely excellent skid resistance performance. A large variety of trials have promoted the successful application of interlocking block pavement and change. Concrete block shape has been created via imitating the brick to refined variety tooth side from the rectangular block, and now it has accomplished the improvement on the extensive reform of the special-shaped block right now. Constantly trials boost and best the interlocking paving overall performance of technique.
