Description

Groundwater withdrawal control device in depth section of groundwater deep well {.}

Generally, in order to collect groundwater, excavate the rock of the surface to the surface layer using a pit of a certain thickness, and then put out the large diameter outcasing to prevent the collapse of the surface layer, and then excavate the rock layer to penetrate the vein. Insert the casing and strainer pipe to prevent the inflow of surface water and inject the concrete liquid into the space between the casing and the inner wall of the groundwater core and install the groundwater core pump and pumping pipe inside the casing. Groundwater was pumped to an external destination. The groundwater well pump has a ground level well pump which starts and stops according to the groundwater level by the upper level switch and the lower level switch installed in the pipe.

When the surface layer and rock layer are excavated in sequence using a plowing machine, several large and small water veins are met. These veins flow through the topsoil in the surface layer, but in the rock layer, veins are generally formed between the rocky and rocky connections. Will be introduced. In general, the surface water flowing from the veins formed in the topsoil layer is often contaminated, and the groundwater taken from the rock layers is clean enough to drink.

Conventionally, in order to check the amount of groundwater collected, the amount of water pushed up by the power of the compressed air supplied through the landing bit and the rod was measured during the excavation process. It is inevitable to measure a lot by taking water which is present and it is preferable to measure it through a continuous pumping period of about one month for accurate amount of measurement.

In order to do this, however, a normal pumping pipe, a well pump and a flow meter must be installed and grouting to block surface water inflow and a strainer to protect the well pump and the well caused by excessive soil inflow into the well. .

The biggest problem in this process has always been a matter of how much groundwater from which depth is coming from.

In order to solve this problem, the present inventors have invented a groundwater depth section water collecting device and are applying for a patent, and are actually getting many achievements in the field. However, even if the groundwater level and the quality of the groundwater have been grasped in the groundwater wells, when the groundwater finally pumped out does not meet the water quality standards, it is inevitably forced to be disposed of. In the case of drinking spring water or groundwater for food and beverage, the extent is extreme. As a result of carrying out environmental impact assessment and groundwater well drilling at enormous cost, some components exceeded the water quality standard due to the geological characteristics, and thus, the wastewater treatment of groundwater wells developed previously is a waste of national assets and resources. It would be a non-realistic treatment situation that could be a factor causing and spreading pollution.

The present invention has been invented to solve all the problems described above as the groundwater through the excavation of the groundwater core well depth of the groundwater core well and the analysis of the samples collected by the pump and pumping groundwater inflow section Even if the water quality can be analyzed in each depth section, if some water quality items exceed the standard due to geological characteristics, the groundwater withdrawal control device in the depth section of the groundwater deep well is controlled and pumped. The purpose of the pumped groundwater to meet the water quality standards is to reduce the incidence of closed air in the groundwater well and to enable economic and efficient groundwater well management.

In general, the configuration of the device for collecting groundwater is connected to the groundwater heart pump and the pumping pipe for pumping the groundwater collected by the heart pump to the outside to draw it to the outside, and the power to start the heart pump It consists of a cable, a high level switch, a switch wire connecting a low level switch, and a water level measuring tube.

The depth of groundwater withdrawal control device of the groundwater core well according to the present invention is equipped with an expansion tube on the outer circumferential surface of the shield barrel held by the wire rope at the bottom of the groundwater well pump and the amount of groundwater flowing into the groundwater well pump side from the bottom of the shield vessel. Characterized in that by configuring a control valve that can adjust.

The shielding cylinder is a cylindrical tubular body, and the expansion tube is mounted on the outer circumferential surface thereof, but the inlet of the pressurized fluid to be injected into the expansion tube is connected to the injection hose by a connection nipple by processing a hole in the body between the inner and outer circumferential surfaces of the cylindrical tube. It features.

The expansion tube is made of a thick rubber material and has a built-in iron core or fibrous braided mesh therein to allow uniform expansion when the expansion tube is expanded.

In addition, the expansion tube is fixed by pressing the upper end and the lower end by the fixed adapter, the fixed adapter of the upper end is fixed to the cylindrical body, and the lower end of the fixed adapter by processing the inner peripheral surface o The ring is installed by sliding the slide along the outer peripheral surface of the cylinder When the expansion tube is expanded by inserting a spring that can be inserted into the outer peripheral surface of the cylinder, the lower fixed adapter moves to the upper side and the expansion tube swells and pressurizes to the expansion tube. When the pressure of the fluid is released, the expansion tube can be easily returned to its original form by the force of the spring.

The expansion fluid pressurized fluid inlet tube is drawn out to the outside, but the pressure fluid inlet tube is attached to the pressure adjusting supply so that the pressurized fluid is continuously maintained at a constant pressure even when minute leakage from the expansion tube occurs. It is done.

Inside the cylinder, the valve seat is machined on the inner circumferential surface and the ring is inserted so that no leakage occurs when the valve stem is positioned on the valve seat.The valve stem is returned by the spring, but the opening is pulled from the top. It is characterized in that the pull can be adjusted.

Hereinafter, the configuration and operation of the present invention will be described in detail.

Depth section of the groundwater depth control device of the groundwater core well according to the present invention is equipped with an expansion tube on the outer circumferential surface of the shielding cylinder that is held by the wire rope at the bottom of the groundwater core pump and the amount of groundwater flowing into the groundwater core pump side from the bottom of the shielding tank It is configured a control valve that can adjust.

The shielding cylinder is in the form of a cylindrical tube, and the expansion tube is mounted on the outer circumferential surface thereof, but the inlet of the pressurized fluid to be injected into the expansion tube is machined into a hole between the inner circumferential surface and the outer circumferential surface of the cylindrical tube so that the injection hose is connected by the connecting nipple. The expansion tube was made to be as long as possible to increase the grounding rate with the inner wall of the groundwater core.

The expansion tube is made of thick rubber material, and if it is made of rubber material only, there is a problem such as excessive expansion in the thin part in the process of injecting pressurized fluid to make a gap. It was built so that a uniform expansion can be made when the expansion tube is expanded.

In addition, the expansion tube is fixed to the upper end and the lower end by a fixed adapter, but the fixed adapter of the upper end is fixed by screwing the tubular body of the cylinder, and the lower end is installed by processing the sleeve on the inner peripheral surface of the fixed adapter, and The inner ring is machined to slide along the outer circumferential surface of the cylinder. The lower part of the fixed adapter has a spring that can be inserted into the outer circumferential surface of the cylinder. As the adapter moves upwards, the expansion tube swells without a great change such as thinning in the expansion tube, and the spring is compressed. In addition, when the pressure of the pressurized fluid is removed from the expansion tube, the expansion tube can be easily returned to its original form by the return force of the spring.

In addition, in order to secure only the expansion force of the expansion tube, it is possible to fill the high-pressure tube band on the upper and lower ends of the expansion tube to have the function of the expansion tube.

Expansion tube Expansion pressurized fluid inlet tube is drawn out, but the pressurized fluid inlet tube is equipped with a high-pressure gas cylinder and a pressure regulating feeder so that the pressurized fluid can be continuously maintained at a constant pressure even when minute leakage from the expansion tube occurs. By doing so, it is possible to maintain the function of the expansion tube for a long time.

Inside the cylinder, the valve seat is processed on the inner circumferential surface, but the valve seat is made in the form of a funnel type, and the o-ring is inserted into the valve seat to prevent leakage when the valve stem is positioned on the valve seat.

The valve stem has a conical body that can be seated on the valve seat, and its end is extended in the form of an annular rod. The end of the annular rod can slide in the center of the fluid passage opening processed in the valve seat. In addition, the upper end of the valve stem is formed, and the return spring is mounted on the unit, and the spring holding ring is maintained by the spring fixing ring, which is fixed on the inner circumferential surface of the cylindrical body by the return spring. To make it possible. At the top of the valve stem, there was a hook to fix the wire rope, which was pulled out to control the opening of the valve.

The valve stem can be installed in different types depending on the high and low pressure of the aquifer aquifer of the groundwater core and the ease of installation and maintenance, and the position of the return spring can also be changed from the top to the bottom.

The present invention thus made,

Through the groundwater depth collection device, groundwater that meets the water quality standard is collected in a certain depth section, while below a certain depth depth, a certain amount of groundwater exceeding the water quality standard is collected and the amount of groundwater is checked. Firstly, it is installed with the cardiac pump and the pumping pipe in the section where the shielding tube is designated. In this case, the shielding box can be connected to the wire rope down by the length measured from the lower part of the heart pump in advance so as to be located at the determined depth, and the shielding box is installed first by connecting a separate wire rope from the outside so that each can be installed in an independent form. The heart pump and pumping pipe may then be installed.

After confirming that the shielding container is located at the intended depth, when the pressurized fluid is injected into the expansion tube, the expansion tube swells and the shielding section is installed. The pressurized fluid injection hose was connected to the high pressure gas cylinder through a pressure regulating feeder to maintain the internal pressure of the expansion tube so that the expansion state could be maintained unchanged.

Chapetons equipped with return springs and expansion tubes, which do not have valves in them and penetrate the pipes, have excellent returning force, so that the effective grouting can be shielded for general ground grouting. It can also be used for teas, and its use can be widely used.

At this time, the ground water below the installation area of the shield box is pressed into the valve seat by the force of the strong spring, so even if the ground water core pump is operated because the shield is blocked, the pump is not pumped. Only groundwater can be collected. In the process of pumping groundwater, if the groundwater and some components of the proper water quality standard are mixed with the groundwater of the sub-shielding section having the water quality higher than the proper standard due to some geological components, Diluted in the groundwater above the installation area of the shield can be maintained below the appropriate water quality standards, the operation of the valve stem was to pull the wire rope to control the opening degree of the valve stem. The valve seat and the valve stem are in the form of a cone, so that even the minute groundwater inflow can be regulated so that a device that can always produce the groundwater of proper water quality can be constructed while operating the groundwater core well. The opening of the valve may be automated even by allowing the wire rope to be wound by a motor operated by a DC power source on the ground water core cover and executing the power and the degree of rotation in the control room.

As the present invention is made, some components are excessively measured due to the geological characteristics below a predetermined depth, so that it is possible to improve the groundwater heart well, which was forced to be disposed of because it does not meet the appropriate water quality standards, and thus can collect high quality groundwater. In addition, the development of indiscriminate groundwater to collect proper water quality can be suppressed, and as a result, it can be an opportunity to prevent groundwater contamination.
