Description

TECHNICAL FIELD [0001] The present invention relates to a permeable block capable of sustaining a water permeable function and a permeable block composition and a permeable block for forming the permeable block,

Field of the Invention [0002] The present invention relates to civil engineering and construction technology, and more particularly, to a permeable block, a permeable block composition for forming the permeable block, and a method for manufacturing a permeable block.

Modern cities are experiencing a dramatic decline in their natural drainage area due to rapid urbanization.

This is caused by the steady outflow of surface water due to rainfall.

Especially, in areas where population is close, 95% of stormwater has been converted to surface water, and the drainage system has reached its limit.

 In addition, the shape of precipitation has also changed considerably due to the influence of abnormal weather including global warming, and the direction is also increasing in the form of concentrated rainfall, and the precipitation is characterized by a concentration in a certain period of time. And the long-term economic and social costs due to water shortages are expected to increase.

Due to this situation, in developed countries, the infrastructure of roads has been continuously improved from the early 1990s to save the stormwater discharged into surface waters into the temporary storage space and to allow natural drainage to the ground, thereby reducing the drainage load. The construction method that can be used is introduced and put into practical use.

However, in spite of the above social necessity and domestic reality, Korea has not developed a construction method suitable for domestic situation.

In addition, due to the risk of flooding damage due to the increase in the incidence of sudden heavy rainfall, advanced countries are continuously expanding the installation of excellent storages.

In Korea, it is time to expand the development of pitcher packaging to increase the ecological area rate of roads, and research and various construction methods have been devised and applied accordingly.

However, the conventional water permeation method is a method using a porous concrete block. In the case of not performing continuous post-management after public use in a domestic urban environment, permeation efficiency is continuously reduced after 2 months of public use, There is a problem that it returns to the level.

In order to solve this problem, in Europe and USA, joint pitcher is mainly used, but in Korea, due to joint regulations (2 ~ 3㎜) at the time of press release, There is a need for a sustainable pitch structure that is appropriate to the situation.

In addition, in the case of the permeable core block developed by complementing the above, the block and the water permeable core are formed as a separate type rather than being integrally formed, so that the waterproof core is difficult to be constructed and the block and the water permeable core are combined, And the block sand and the water permeable core are respectively rotated and settled, thereby causing a problem of a large amount of breakage of the sidewalk.

As such, there is a lack of technology development related to the pitching of roads in Korea at present, and there is a considerable problem in maintenance.

If the problem is not solved fundamentally and only the surface block of the press block is replaced with a pitcher, defects such as unbalance and settlement of the press block due to loss of the lower permeable layer after the common will occur, The reduction will result in loss of functionality.

Most of the pavement packaging currently in operation in Korea does not have a standard for the maintenance and evaluation of the post-public function, and it can be considered that it is practically impossible to install the pavement that can be evaluated.

In addition, since the method of recovering the permeability index to the existing level after the decrease of the permeability index is not established, practically it is difficult to maintain the function continuously except for the initial construction.

Although it is possible to recover the permeability coefficient at the initial stage of installation through management using professional equipment, since it is not possible to use large equipment due to the present conditions in Korea, in order to manufacture a permeable block capable of sustaining permeability in Korea, It should be converted to a permeable block of the type.
