APPARATUS FOR PREVENTING POLUTION OF SUBTERRANEAN WATER}

The present invention relates to an upper pollution prevention device of an underground water hole, and more particularly, by connecting a pumping pipe and a water supply pipe with a discharge head of a "∩" type, and pressing and supporting the discharge head so that the pumping head and the water supply pipe are watertight. In addition to preventing the contamination of the upper surface of the groundwater hole to prevent the separation of the water supply pipe and the water supply pipe relates to a pollution prevention device.

As is well known, groundwater refers to water that fills or flows through gaps between underground strata and rocks, and in recent years, various pollutants are mixed with groundwater to deteriorate the quality of groundwater.

In order to solve the above problems, conventionally, by installing an upper protection facility in which the periphery of the groundwater is higher than the ground, it blocks the inflow of contaminated surface water or installs a cover device to prevent the contaminated material from entering the groundwater core.

However, the groundwater core cover device remains open, so in the case of normal habitats such as insects or floods, contaminated surface water flows into the groundwater core without any resistance, which inevitably results in serious groundwater contamination. It was in condition.

Therefore, in order to improve the problems of the conventional open groundwater well cover device, techniques have been proposed in which the groundwater true cover device is hermetically sealed so that the pollutant does not flow from the top of the groundwater well well.

However, the conventional hermetic groundwater core cover device has the effect of completely sealing the inside and outside of the heart well, the following problems occurred.

In order to completely seal the inside and outside of the heart well with the groundwater well cover device, it is also important to closely shield the groundwater well closed cover and the outcasing inserted into the ground and drawn out to the top of the ground, but depending on how the water supply pipe is combined from the pump pipe Since the size and structure of the upper protective manhole can be determined, this is also an important factor. In more detail, in the related art, a problem arises in that a check valve, a water meter, and a shut-off valve that are sequentially connected by a pump pipe on an upper part of a hermetic heart cover cannot be configured together with a body such as a hermetic heart cover.

In the process of installing the sealed heart well cover, various measures to reduce the installation cost of the upper protector installed to protect the sealed cover from external influences have been studied together. In order to meet, it is necessary to input heavy equipment such as a fork-lane and a lot of manpower is required, resulting in a high cost of installing the upper protection. This was the reason for the requirement to freely specify the size of the upper guard when the groundwater law was amended to install the sealed heart well cover.

In addition, conventionally, when the groundwater deep well pump is lifted, the pumping pipe installed on the ground is also separated, and a high cost is required due to the reason that a professional plumbing technician is required in the separation and recombination process. It became.

In addition, in the case of some devices to reduce the inner diameter of the out casing in the process of manufacturing the structure to the closed type, this causes a problem that the workability in lifting and re-installation of the groundwater well pump and pumping pipes.

In addition, in the case of a small-sized diameter groundwater well, a pumping pump is usually installed in the ground and a jet device is installed in the core to form a pumping pipe. The conventional airtight cover device maintains the same level as the surface of the ground and discharges and feeds the groundwater core. There were problems such as the inability to connect spheres.

In order to solve this problem, the utility model No. 351888 has been proposed an upper pollution prevention device for groundwater work.

The prior art can balance both sides of the motor pump to improve watertightness, but the connector and the fixing means are simply inserted into a wedge, so buoyancy caused by the groundwater introduced into the intake pipe is generated. There is a problem with this deviation.

The present invention is to solve the above problems, by sealing the upper inlet of the groundwater to prevent the contaminants of the ground flow into the groundwater, and also to tightly connect the pump and water pipes for pumping and supplying groundwater In addition, the object of the present invention is to provide an upper pollution prevention device of the groundwater hole so that the groundwater is not separated during the pumping.

That is, a gap exists between the first and second cylindrical portions 21 and 22 due to the difference in diameter, and the discharge end 32 of the discharge head 30 is connected to the gap. At this time, since the discharge head 30 is connected to only one place of the upper casing 20, it is preferable that the second cylindrical portion 22 is eccentric to one side of the first cylindrical portion 21 so as to make the most of the limited space. That is, the flat plate-like discharge part 23 is formed between the first and second cylinder parts 21 and 22.
