Description

TECHNICAL FIELD [0001] The present invention relates to a manhole having a detachable filter screen and a rainwater storage facility using GMT material. [0002] JOINTED FACILITIES KEEPING RAINWATER USING GMT MATERIAL AND DETACHABLE FILTER ELEMENT [

The present invention relates to a prefabricated rainwater storage facility using a manhole and a GMT material having a detachable drawing screen, and more particularly, to a rainwater storage facility capable of easily removing foreign matter contained in rainwater and leaching rainwater into the ground The present invention relates to a prefabricated rainwater storage facility using a GMT material and a construction method thereof.

As city development progresses in earnest, the rainwater that permeated into the ground before development is leaked to the river through the surface and drainage facilities at the same time, causing urban environmental problems such as flood damage, downtown heat island phenomenon and water shortage phenomenon.

These urban environmental problems can cause floods due to the increase of buildings or the increase of the packing rate of the land, as stormwater does not flood underground at the time of storm, and flows into urban sewer or river at a time.

In addition, in urban areas, when the amount of inflow to the river is small, the water quality deteriorates and the groundwater becomes depleted. For this reason, research and development of a technique for storing rainwater in a rainwater storage facility composed of concrete or synthetic resin once installed in the field and controlling the flow rate to the stream are being studied and developed.

In other words, the development and commercialization of rainwater storage facilities is being actively conducted both domestically and abroad, and the size of the market is expected to grow significantly.

In particular, the rainwater storage facility is mainly made of concrete, but in recent years, an underground storage facility that can be used for a long period of time due to environmental friendliness or space saving is required and an economical installation is required. In addition, Plastics (especially poly-propylene) are attracting attention as a material for rainwater storage facilities in terms of gender.

In the underwater penetration apparatus of the rainwater storage and utilization apparatus using the prefabricated pore block which surrounds the whole with the pavement brick material of Patent Document 1, which is the background of the invention, several permeable permeable blocks are embedded in the permeable fabric, A rainwater storage frame is formed. The rainwater flowing into the structure of Patent Document 1 slowly permeates into the ground through the permeable fabric while the external earth particles can be prevented from entering and accumulating in the structure, So as to prevent flooding.

On the other hand, in the case of Patent Document 1, the porosity infiltration block does not have sufficient rigidity to sufficiently bear the load, and plastic clips and plastic rods are used as fasteners for assembling the respective porosity infiltration blocks. In the case of a storm water retention frame, it is not possible to give sufficient rigidity to the timber structure, especially the joints. In the case of a rainwater retention frame, the foreign matter contained in the rainwater stored in the storm water retention frame is deposited over time. there is a problem.

On the other hand, Patent Document 2, which is the background of the invention, uses a block that forms an inclined surface that can facilitate construction and shorten the construction period.

However, the rainwater storage facility of Patent Document 2 is provided with a block made of a material of glass-fiber mat reinforced thermoplastic (GMT), which increases the inflow efficiency of the rainwater or directly inflows rainwater into the rainwater storage frame , Or there is no means for directly removing the foreign matter.

In addition, the rainwater storage facility of Patent Document 2 does not have a plurality of means for filtering out foreign matter instead of introducing rainwater into the rainwater storage frame itself, and thus the foreign matter removal efficiency and the rainwater storage efficiency are very low.

These disadvantages are also encountered in Patent Document 3 of the period after the technical development.

Therefore, it is difficult to obtain the strength equivalent to that of conventional concrete products because of the strength limit of the material itself, and the rainwater storage tank made of PP is pointed out as a problem of stability.

In addition, in the case where the foreign matter contained in the rainwater stored in the rainwater storage facility is immersed over time, there is a problem in the treatment thereof, and development of technology for drastically improving the stability and maintenance of the strength of the plastic material It is a matter of urgency.

The GMT material is an abbreviation of Glass-fiber Mat reinforced Thermoplastic. PP (Poly-Propylene) which is a kind of thermoplastic resin (thermoplastic resin that can be melted by heat) is used as a base material, and glass fiber -fiber) is added.

The GMT material is a high strength composite resin produced by weaving glass fiber into a nonwoven fabric and impregnating it into a polypropylene resin. It is a composite material that satisfies both tensile strength and weight reduction of a plastic in accordance with a cold rolled steel sheet.

The GMT material is mainly used for bumper, front end carrier, and undercover and body materials as automobile parts, and is used as an industrial material for container inner wall and air conditioner base. The material to which the glass fiber is added to the PP is Filler which is added to the PP itself or LFT (long-fiber reinforced thermoplastic, GMT may be included in a broad sense), but the biggest differentiating feature of GMT is glass After the fibers are woven in a similar manner to a nonwoven fabric (commonly referred to as Mat), the mat is impregnated with PP. Due to this Mat structure, it is possible to have a higher strength than PP added with other glass fibers.

In addition, there is a case where the rainwater is present excessively such that it can not be stored inside the rainwater storage case 1. In this case, the rainwater flows out from the foreign matter removing hole 600 (see FIG. 11) installed around the rainwater storage frame 1, and then flows into the outflow pipe 4, the one manhole 800, the connecting pipe 870, (See FIG. 11) around the rainwater storage frame 1 via the manhole 800a and the overflow drainage pipe 5 and thereafter flows into the drainage pipe 700 connected to the inspection hole 700 ). ≪ / RTI >

As described above, the manholes 850 of the manholes 800 and 800a pass through a separate water-permeable or car-shape sheet (not shown) surrounding the rainwater storage frame 1, And can be installed on the upper part of the rainwater storage frame 1 by using the manhole mounting hole 90.

Therefore, the rainwater passing through the manhole cover 860 and the sieve 810 of each of the manholes 800, 800a can be introduced into the inside of the rainwater storage frame 1 through the vertical pipe 850.

For example, referring to FIG. 11, in the case of the penetration type, the rainwater storage frame 1 formed by assembling the block is embedded in the ground or the ground 2. In this process, a plurality of manholes 800 and 800a as described above are also installed on the upper part of the rainwater storage frame 1.

In the normal case, the path of the rainwater can be introduced into the rainwater storage frame 1 via the outflow pipe 4, the manholes 800, 800a and the vertical pipe 850 of the foreign matter removal hole 600 have. When rainwater overflows, such as a typhoon, heavy rain or the like, the movement path of the rainwater passes through the outflow pipe 4, the manholes 800 and 800a, the connection pipe 870, and the overflow outflow pipe 5 (Not shown) via the inspection hole 700 through the check hole 700.
