Description

{Multi-Functional Well Using Hydraulic Packer}

The present invention relates to a multifunctional pipe to which a hydraulic packer is applied. More particularly, the present invention relates to a multifunctional pipe that is used for complex purification of contaminated soil and groundwater by means of Soil Vapor Extraction (SVE), air- By applying various functions such as air-stripping, oxidation (Oxidation) and groundwater circulation, the inner packer can flow and efficiently purify contaminated soil and groundwater, The present invention relates to a multifunctional apparatus using a hydraulic packer capable of responding quickly.

In recent years, pollution of soil and groundwater by heavy metals, oil and other harmful substances has become a serious environmental problem in facilities such as oil production and storage facilities, organic solvent storage facilities of industrial complexes, military unit oil and detergent storage facilities. As the pollutants released from the facility area pass through the non-paved areas of the soil and contaminate the ground water, various techniques are used to recover the contaminated soil layer containing the contaminated groundwater together with the contaminated groundwater.

Soil Vapor Extraction (SVE), Air-Sparging, Air-stripping, Oxidation, Groundwater (Groundwater) circulation) are known.

However, soil contamination is difficult to identify information related to the identification and scope of pollutants. Even if the contamination concentration is checked through soil pollution survey at the time of application of the restoration treatment technology, And so on. In addition, most of the polluted areas in the soil are contaminated with groundwater as well as the soil. However, there is no technology to purify the soil and groundwater at the same time, There is a limitation in that it can not be flexibly coped with.

That is, pollutants exist as gaseous pollutants in the soil pores, pollutants adsorbed on the soil, light pollutants floating on the underground water because they are lighter than water, and pollutants dissolved in the groundwater. Since there are various pollutants such as this, it is almost impossible to purify the existing ground treatment technology to the restoration target with only a single technology. Therefore, various ground treatment techniques should be applied. Accordingly, the restoration treatment facility is installed separately The operation period is long, the installation cost is increased, and compatibility with various processing technologies is not high, so that a separate system must be installed.

In order to solve the above-mentioned problems, there has been proposed an in-situ composite restoration technique capable of simultaneously purifying soil and ground water contaminated with organic substances, heavy metals, and the like, as disclosed in Korean Patent Publication No. 462118 (2004.12.07.) Is a dual definition method for independently injecting / extracting air into and out of the unoccupied zone of the soil and the aquifers, respectively. Separately preparing an aeration tank for injecting air; Forming a screen for injecting and extracting air into the lower portion of the non-paved zone injection / extraction definition and the lower portion of the aquifer injection definition zone, respectively; Inserting an air supply pipe having a length longer than the non-pouring zone injection / extraction information into the non-pouring zone injection / extraction channel; Installing a blocking block for sealing the inner peripheral surface of the non-pouring base injection / extraction definition and the outer peripheral surface of the air supply pipe at the upper and lower positions of the non-pouring base injection / extraction definition; And coupling the lower end of the non-canister infusion / extraction definition and the upper end of the aquifer infusion definition so that the air supply pipe is in communication with the aquifer inlets. Accordingly, Can be performed at the same time.

In addition, Korean Registered Patent No. 1127223 (Mar. 03, 2012) discloses a connection pipe for an aeration tank, a connection pipe for an unsaturated layer, and a low density water-insoluble material (LNAPL), each of which is independently installed and fixed with a packer, A tubular casing including an extraction tube therein; And a horizontal pipe for injecting the surfactant extending in the waterline direction with respect to the tubular casing, wherein the horizontal tube for injecting the surfactant is constituted by a structure located in an unsaturated layer of the soil or a sand layer filled in the upper part of the unsaturated layer It is known that a multifunctional structure capable of greatly reducing the number of gutters and the injection / extraction device and simultaneously treating the aquifer, the unsaturated layer, and the low density water-insoluble material (LNAPL) is also known.

However, in the case of the above-mentioned JP-A-462118 and JP-A-1127223, since both of them are applied to various devices for purifying respective pollutants, it takes a great deal of time to manufacture and install the facility, It is structurally weak so that it is practically impossible to apply it.

Particularly, in the above-mentioned prior art, since the blocking block of No. 462118 and the packer of No. 1127223 are all fixedly installed in the tubular structure, it is difficult to cope with the situation where the contaminants are floating, Thereby significantly lowering the functionality and operating efficiency of the battery.
