Description

BLOCK TYPE RAIN RETAINING FACILITY}

The present invention relates to a block type storm reservoir, and more particularly, to a block type storm reservoir formed by a plurality of precast concrete blocks connected in fluid communication.

Recently, with the development of the city, various structures such as buildings, asphalt, concrete pavement, and parking lot facilities are rapidly increased, and rainwater (excellent) flows directly into rivers through rainwater pipes, flooding rivers, deteriorating soil moisture, and groundwater Changes in the natural water cycle, such as depletion, have increased the likelihood of heavy rainfall or drought caused by climate change.

The disasters such as urban flooding, heat island phenomenon, water exhaustion and ground subsidence are caused by development-oriented policies that ignore the natural environment in order to pursue a comfortable and pleasant life.

As a result, there is a demand for continuous development for the coexistence between the natural world and human beings, and consequently, rainwater is penetrated or stored underground to use as a new source of water before it flows into the stream. Rainwater reservoirs are being applied as part of efforts to restore the circulation.

Conventional rainwater storage tank is a method of building a concrete site in the ground and the prefabricated by precast concrete panels.

The former method of casting in the field takes a long time for curing, which results in a long air and a high construction cost.

The prefabricated by the latter precast concrete panel has the advantage of shortening the air compared to the site casting, Republic of Korea Patent No. 10-1052857, Republic of Korea Patent No. 10-0576508, Republic of Korea Patent No. 10-0702860 Etc.

In the prefabricated rainwater storage tank of the conventional precast concrete panel, a column is erected on a bottom plate and a ceiling plate is installed on the column, and since the internal storage part of the rainwater storage tank is not partitioned and is made of a single space, in terms of use of rainwater, There is a problem that the efficiency is lowered, the air is long because the number of pillars for supporting the ceiling plate increases.

In addition, precast concrete products are manufactured according to the design of storm water storage tanks, and because they cannot be shared with storm water storage tanks of different sizes, many sizes of products suitable for various storm water storage tanks must be produced, thus handling (production, storage, transportation, etc.). ) Is difficult.

And, because the prefabricated rainwater storage tank is made only by the combination of the block and the pillar, there is a problem in that damage and settlement of the rainwater storage tank are generated because the force against the load transferred from the upper facility is weak.
