Description

[0001] The present invention relates to a prefabricated manhole for improving water quality,

The present invention relates to a manhole that collects and discharges a predetermined amount of rainwater flowing down around a road in a rainy season. More particularly, the present invention relates to a manhole for flowing rainwater on roads without flowing sludge on various roads, So that the occurrence of bad odor is remarkably reduced due to the fundamental inflow of the sediments, and there is no fear of theft of the lid due to the fact that the steel structure such as the lid is not required at the upper part, The present invention also relates to a prefabricated manhole for improving the quality of the water, which can provide a more pleasant and pleasant urban environment by closing the upper exposed surface with a wooden cover or the like.

Recently flood damage has been frequently caused by unexpected local showers due to abnormal weather.

The root causes are various, but one of them has a house collecting rainwater to collect rainwater in many places in order to deal with the rainwater flowing on the road in the rainy season.

However, various pollutants left on the road such as fallen leaves, soil, and various household garbage are allowed to enter into the house, so that they can be left for a long time and deposited. And flood damage has occurred.

In order to prevent such damages, it is necessary to manage the dredging periodically using separate manpower and equipment, but it can only be managed by limited budget due to lack of budget. In addition, odor is generated due to the corruption of various sludge deposited inside the house, and another complaint may occur.

Conventionally, in order to solve all of these problems, a ring-shaped manhole cover 2 is seated on an entrance 10 of a manhole 1 in a domestic registration application No. 20-0414415, and an upper opening end of a manhole cover 2 The manhole cover 3 has a manhole cover 3 for opening and closing the manhole entrance 10. The manhole cover 3 has a center fender 30 on which a plurality of drain holes 32 are formed, The protective frame 34 protrudes upward along the outer periphery of the fender 30 to form a vegetation space 35 therein and at least a small diameter smaller than the outer diameter of the protective frame 34 And the vegetation soil 4 is filled in the vegetation space 35 by the protection frame 34 and the herbaceous plant 5 is planted in the vegetation soil 4 It can be applied to sewage, road, river and environmental facilities construction However, the manhole cover as described above may cause problems in cost increase due to the manufacture of the manhole cover and the manhole cover, which are iron structures, and frequent theft of the manhole cover and the manhole cover, which are expensive structures. will be.

In order to solve the above-mentioned problems, a manhole cover, which is a steel structure, is not required on an upper part of a manhole having an integrated circular or quadrangular outer shape, and various sludge and rainwater, , Gravel, vegetation soil, etc., and collecting and discharging the rainwater while filtering the rainwater. The object of the present invention is to provide a prefabricated manhole for improving water quality.

In addition, the rainwater flowing into the upper part of the manhole is firstly filtered through crushed stone, gravel, vegetation soil, etc., and the primary filtered rainwater is secondly filtered through the filtration filter to collect the rainwater into the rainwater inflow chamber, And to provide a prefabricated manhole for improving the quality of water, which is capable of discharging rainwater that is further improved in water quality by thirdly filtering the second filtered rainwater collected by the filter screen screen.

It is also an object of the present invention to provide a prefabricated manhole for improving the quality of water, which is capable of planting vegetation plants as well as filtration of rainwater by sequentially laminating a fiber mat, sand, crushed stone or gravel, and a soil layer on top of a manhole.

The present invention relates to a manhole (10) made of a concrete material having an inner hollow shape and a circular or rectangular shape and having a primary filtration function of rainwater flowing into the upper rim (11) And a plurality of filtration holes 120 formed in the intermediate partition wall 110 so that the inflow rainwater is discharged to the lower portion of the intermediate partition wall 110. The intermediate partition wall 110 is formed of a concrete material, A rainwater inflow section 100 of a lowered shape;

And a rainwater inflow chamber 200 formed below the middle partition wall 110 of the rainwater inflow section 100 and discharging rainwater collected through the filtration hole 120 to a sewage pipe connection port 210 formed at a lower part thereof The present invention relates to a prefabricated manhole for improving water quality.

The present invention has a great effect on the ecological river composition by allowing rainwater to pass through the crushed stone or gravel layer and filtering the rainwater stepwise through the filtration filter and the filter screen net to flow into the river with excellent water quality in terms of water quality turbidity evaluation, There is an effect that cost for water treatment can be reduced because no separate water treatment cost is generated.

In addition, the rainwater filtration function installed on the top and inside of the manhole reduces sediments inside the manhole, which makes it possible to collect and discharge the rainwater smoothly during the rainy season. Therefore, it has an excellent effect in preventing flood damage in the city center, It is possible to provide a more comfortable urban environment by basically blocking the odor generated by the corruption of various kinds of garbage accumulated inside the manhole.

In addition, the use of cheap materials such as wood, gravel or crushed stones can reduce unnecessary budget waste, can dramatically reduce the cost of facility construction, and can be used to periodically clean the manhole The maintenance for dredging has the effect of significantly reducing the economic burden used in manpower and equipment.
