Interlocking blocks are a new form of paving introduced in the mid-1980s. Due to its unique advantages, the interlocking block has been applied to yard engineering in many ports and has gained great social and economic benefits.
Block interlocking paving is made by arranging blocks of high strength and precision of precast cement with a special method and filling the seams between them with sand. Under the action of an external load, the loads under the block are distributed in conjunction with each other, rather than occurring separately. The thickness of interlocking blocks is usually 8cm, 10cm and 12cm.
Interlocked block layers, cushioned sand layers, base layers and ground.
Interlock block layer is different from other paving structures. It works not only as an abrasive layer, but also as a structural layer (overall load balancing). Blocks can take different shapes and draw different patterns to make the environment beautiful.
2. The role of the cushion sand layer is to level the base and provide the necessary conditions for the surface layer to form a tight embedded lock.
Base layer and ground are almost indistinguishable from normal asphalt paving.
4. To ensure interlocking between blocks, an edge constraint is required to limit the lateral displacement of the blocks under the drive load.
The interlocking block layer consists of pre-cast concrete blocks and joints. Interlocking block gap filling material is usually mixed with fine sand, or small amounts of lime or cement. sun The authors found that, compared to cement concrete paving, damage to interlocking block paving is generally limited to breaking of interlocking blocks, because the interlocking blocks are smaller, the slab properties are less noticeable, and the joints are unable to transmit tensile stress. Not pointing out that most are damage to the base or ground.
The mechanical properties between the filler and the interlocking block are continuous during compression and detachment during tension.
In interlock block paving, interlock block herringbone paving is commonly used in engineering because it is superior to cis paving.
The pros and cons
Germany, the United Kingdom, Australia, South Africa, the Netherlands, Japan and other countries have carried out various tests to clarify the characteristics of the block connection pavement. Their general conclusion is as follows.
Blocks cannot withstand the load independently.
Most researchers believe that the shape of the block affects the paving performance. The interlocking performance of the shape block is usually better than that of the rectangular block, and the interlocking performance of the four-sided block is better than that of the two-sided block.
Interlocking block the pavement can withstand large deformation without damage.
Compared to asphalt paving, block-linked paving has a greater springback bend.
Interlocking block damage to the pavement is usually not due to block destruction, but to block shear punch on the base and accumulation of excessive road surface permanent deformation.
6. Interlocked block paving has excellent sliding resistance.
Many experiments have succeeded in applying and improving closed walkways. The shape of concrete block developed from imitation brick to refined rectangular tooth edge block, and today it has developed into a comprehensive reform of special shape block. The degree of perfection that links continuous improvement with the performance of the pavement system.
Features of high-strength concrete interlocking block structure
High-strength concrete interlocking blocks used in modern ports have the following characteristics.
1. Mechanical strength is excellent in
The interlocking block is a block structure formed by strong extrusion and strong vibration of high-strength concrete. The main raw materials are cement and very dense aggregate. Therefore, the interlocking block has the characteristics of high density and high strength, and the surface is not easy to rise or break.
2. Simple quality control and quick construction
Linkage block factory facilities through prefabricated factory can be processed by the rapid characteristics processing speed, small, easy to transport, not infected environment against the actual construction after completion is, as long as in infrastructure very fast the construction can be implemented and muraji The block has been simplified to some extent.
3. Maintain convenience
The structure of the interlocking block is a surface layer structure. Because it carries a relatively large load during the process of use for a long time, it breaks if used for a long time. In this case, the damaged interlocking block can be removed from the storage yard and w replaced.以上翻译结果来自有道神经网络翻译（YNMT）· 通用场景
