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



Cement concrete interlocking concrete blocks mould can be a new type of space type, which was introduced to our country in the mid - 1980 - s, and because of its distinctive superiority, so far in our nation, its application has been in the several terminal yard project, and has produced 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 part of wearing layer, and plays a role of structure layer (general diffusion load), and its block might be made into various shapes to make all sorts of design beautify the atmosphere.
1. The part of sand mat layer is leveling at the grass-roots level, and offering required situations for surface formed closely interlocking.
2. The base and subgrade with ordinary asphalt pavement is practically no difference.
3. Edge constraint is actually a have to, whose function is always to limit lateral displacement of block on the road beneath the action of auto loading, as a way to ensure the interlock between the blocks. Germany, Britain, Australia, South Africa, the Netherlands, Japan and other countries have produced various 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 aren't independently bearing the carrying capacity.
2. Most researchers believe that the shapes of block have an effect on pavement functionality that special-shaped pieces of interlocking efficiency are often much better than rectangular block, and efficiency of 4 edges of interlocking block is better than that of the interlocking blocks on both sides on the body.
3. The interlocking block paving can withstand the huge deformation with no harm.
4. Compared with asphalt pavement chain block pavement rebound deflection is bigger.
5. The harm on the interlocking block paving is usually not due to the fault block, but due to the block is washed to the cut into the base, and also the way is accumulated to become permanent deformation (rutting)
6. interlocking moulds possess the extremely great skid resistance overall performance. A sizable quantity of trials have promoted the profitable application of interlocking block pavement and adjust. Concrete block shape has been developed via imitating the brick to refined sort tooth side of the rectangular block, and now it has achieved the development on the extensive reform on the special-shaped block nowadays. Constantly trials boost and best the interlocking paving efficiency of program.
