Description

Groundwater core dropout lifting device {.}

The present invention is the excavation bit frequently generated in the process of excavating the ground and rock to collect the groundwater, the lifting at the time of the breakage of the excavation rod extending by connecting the excavation bit and the drop of the groundwater heart pump or pump pump in operation Groundwater core dropout for forcibly lifting the inserted casing pipe to maintain a certain gap with the groundwater core wall and groundwater core to prevent the sinking of the inner wall of the groundwater and to maintain the filler such as gravel and sand in the excavated core. It relates to a lifting device.

As industrialization progresses in recent years, environmental pollution is intensifying and interest in clean drinking water is increasing. Therefore, in recent years, researches on devices for purifying tap water or surface water and devices for developing uncontaminated groundwater have been intensified.

In general, the groundwater harvesting device, which is preferable for groundwater wells, is excavated to the rock bed using a rocker formed by an excavation rod extending to reach a certain depth by connecting an excavation bit of a predetermined thickness with a drilling bit of a predetermined thickness. Out diameter of large diameter installed to prevent collapse, and excavation of the rock casing after drilling the outcasing again to penetrate the groundwater vein, preventing the sinking of the inner wall of the groundwater, and the constant flow velocity of the groundwater in the rock vein Encasing pipe is installed to secure the space for filling the filling material such as gravel and sand to maintain, and to prevent the inflow of soil water or foreign matter in the ground where the groundwater is moved to the lower portion of the casing and to maintain the proper flow rate Pipes for strainers and the casing pie Concrete and cured concrete that is injected to prevent inflow of foreign substances such as surface water into the space of the inner wall of the groundwater core well and installed in the encasing, and is connected to the heart pump and is pumped up by the heart pump The ground consists of pumping pipes through which groundwater flows. The heart pump is heat-set by the upper level sensor and the lower level sensor installed in the pumping pipe.

In addition, the encasing is provided with a water level measuring tube that can monitor the level of the groundwater to a certain depth.

Conventionally, in order to meet the contracted amount by collecting ground water, excavation is carried out deep into the rock bed, and in this process, the drilling bit or the excavation rod is broken in the underground core of several tens of meters or hundreds of meters. Although there was a considerable amount of cost due to the lack of equipment or equipment, waste air treatment was inevitable, and pumping pumps and pumps installed to collect groundwater were either in operation or during the maintenance or installation process. In case of dropping out and falling into the heart, the salvation is difficult, and in many cases, waste republicing is inevitable, and groundwater contamination is also inevitable due to corrosion of buried droppings and heavy metal leakage.

In addition, in order to meet the contracted quantity, in order to prevent the inflow of contaminated surface water, the insertion depth of the out casing, which is to be pushed up to a part of the rock line, was often pushed only to the middle of the weathered rock layer. In the case of inducing pipe, grouting pipes have not been grounded in many groundwater wells, and the cores embedded with some synthetic resin encasing pipes are also used to prevent the inflow of surface water. In many cases, even if it is not properly installed, even if it is properly constructed, the contaminated surface water flows into the groundwater well without any disturbance due to the cracking of the grouting section, and is mixed with clean rock groundwater as a result. The case has caused a lot of diffuse pollution.

In the case of groundwater cores where such casing pipes are constructed, when the grouting section is to be reconstructed to obtain only clean rock water without contaminant index water, the incasing pipes inserted inside the groundwater core wells are lifted as a whole and then reinserted. I had to do it, but it was difficult because there was no proper method,

The grouting liquid is filled only inside the casing pipe and the space between the outer circumferential surface of the casing pipe and the inner wall of the groundwater core is not filled with grouting liquid. It was difficult to restore the original closed hole completely, so that the groundwater contamination could not be blocked without lifting the encasing pipe. However, there was a problem that a proper method for lifting was not developed.

The present invention has been invented to solve the above-mentioned conventional problems,

Providing technologies and devices that can easily lift when excavating bits or excavating rods generated during the excavation process or dropping of pumping pumps or pumping pipes, it prevents the occurrence of groundwater waste holes and groundwater contamination. By making the pipe easier to lift, the inner wall of the groundwater well is improved to form a space without encasing, so that it is possible to accurately grasp the state inside the groundwater well at the time of construction, and to obtain the information to establish an appropriate construction plan. It is. In addition, it is easy to install and insert a new grouting encasing pipe and retry grouting construction to prevent and improve the contamination of groundwater in the rock aquifer due to the inflow of contaminant surface water, It is an object of the present invention to provide an apparatus and method for lifting groundwater core debris that enables a countermeasure to fundamentally shield the inflow of contaminated surface water.

The present invention is the lifting of the excavation of the excavation rod extending by connecting the excavation bit or excavation bit that occurs frequently in the process of excavating the ground and rock to collect the groundwater, and the dropping of the groundwater heart pump or pump in operation Lifting groundwater core dropout to forcibly lift the inserted casing pipe to maintain a certain gap with the groundwater core wall and groundwater core to prevent the sinking of the inner wall of the groundwater and to maintain the filler such as gravel and sand in the excavated core.

Hereinafter, the present invention will be described in detail.

[First Embodiment]

In order to lift the encasing pipe for the restoration of the closed hole or reconstruction of grouting, the facilities installed inside the groundwater core well, such as the core well pump and power cable, and the water level measuring pipe, the pumping pipe, and the level sensor It is to be lifted to the outside and to form the groundwater core inside in the hollow state.

Then, using the cardiac camera, grasp the shape of the inner wall of the cardiac well by the depth and the installation form of the casing pipe, connect the lifting wire rope to the lock connection bolt attached to the upper lifting device, and connect the fluid injection hose to the fluid inlet. The emergency lifting rope is connected to the emergency lifting eye bolt to lower the lifting device into the groundwater well.

The lifting device is largely integrated with the expansion tube at the lower end of the expansion tube and the expansion pipe at the bottom of the expansion tube and the locking connection bolt for connecting the expansion tube and the lifting wire rope, and the emergency lifting eye bolt. The ring consists of an interpolated sliding part.

The expansion tube is cylindrical in shape and press-fixed and fixed to the water pipe by using a pressing ring at the top of the water pipe of a certain length, and the water pipe and the expansion tube more firmly by tightening the fixing nut of the expansion tube formed at the top. To be unified. The expansion tube was braided with an iron core on a double rubber plate reinforced to prevent it from bursting under the pressure of a high pressure pressurized fluid, and its outer surface was roughly finished to increase friction.

In addition, the outer circumferential surface of the expansion tube was to be able to selectively cover the expansion tube for the protective cover.

In addition, the lower end of the expansion tube is fixed to the sliding portion After inserting the expansion tube to the (yo) part, it was fixed to crimp

Inner side of the sliding part in contact with the water pipe The ring was inserted so that the pressurized fluid flowing into the expansion tube did not leak to the outside when the expansion tube was moved upward in the expansion process.

In addition, the lower portion of the sliding portion to form a round thug so that when the lifting device is lowered into the heart well, the insertion of the lifting device is not prevented due to the protrusion inside the heart.

The fixed nut was machined with an emergency lifting eye bolt to connect the emergency lifting rope to it, and the fluid inlet was connected to the expansion tube through the water pipe.

The end of the tubular pipe was machined with a male thread so that the buffer rubber nut was combined so that the lifting device was installed in the groundwater core or the end was not damaged during the transport operation.

In addition, in order to lift the pump or cardiac pump dropped during operation or during operation, the camera lens and lighting lamp were connected at the end and the camera cable was connected to draw out.

The upper part of the pipe can be used to form a reinforcing grate on the outer surface of the pipe, and to machine the hole so that the locking bolt can be inserted into a thick, flat protrusion plate to withstand sufficient lifting force. The female thread part was processed. The lifting hook is detachable to the water pipe by the lock connection bolt.

The water pipe is made of a material that is not cut or damaged even with high lifting force. Fine trimming is done to prevent damage to the ring.

The present invention configured in this way,

After grasping the installation of the groundwater core well wall and the incasing pipe by the specially designed endoscope camera specially designed to identify the primary groundwater well, the lifting device of the present invention is placed in the lifting wire rope and emergency lifting rope) and the fluid inlet. The connected fluid injection hose is lowered together. At this time, the round extremity of the sliding part helps the lifting device to be caught by the surrounding protrusions.

After the lifting device is lowered, the expansion tube is expanded by supplying compressed fluid to the expansion tube, which expands between the inner casing pipe and the outer circumferential surface of the water pipe, thereby obtaining a strong compressive force.

In this case, the compressed fluid generally uses clean water which does not affect the groundwater quality when the expansion tube is damaged. When the expansion tube is expanded, the expansion force of the expansion tube itself is limited due to the iron core yarn inserted into the expansion tube, and the sliding tube moves upwards along the outer circumferential surface of the water pipe. At this time, the pressing force with the casing pipe is made more powerful.

At this time The ring serves to block high pressure fluid from leaking to the outside.

When expansion of expansion tube is completed and fixed to the casing pipe, it is possible to connect the lifting device or crane to the lifting wire rope to execute the lifting from the outside, and the strong lifting force is connected through the lifting wire rope. And the lock connection bolt, the water pipe, and the expansion tube are delivered to the casing pipe. As a result, the casing pipe is gradually lifted to the outside.

At this time, the groundwater contained in the inside of the casing pipe is discharged to the lower portion through the inside of the water pipe, so that the groundwater does not fall out, thereby avoiding the increase of load, and as the lifting device rises, air is lifted through the water pipe. By allowing the inflow to the lower part of the device, it is possible to prevent an increase in lifting force due to the vacuum phenomenon that may come from the lower part of the lifting device.

If the lifting part fails due to a strong lifting force such as a lifting machine or a crane, the lifting device fails to be lifted by the fluid injection hose due to its own load, and remains inside the groundwater well. As a result, groundwater core wells may not be used. To prevent this, emergency lifting ropes are installed.

If the lifting fails, the fluid discharge valve installed on the outside is opened to discharge the fluid pressurized into the expansion tube to the outside. At this time, the lifting device is returned to the initial free state inside the in casing pipe. As a result, salvage recovery is easily achieved.

In addition, by making and installing the meter reading on the emergency lifting rope, it is possible to check the installation depth of the lifting device and the depth at the time of lifting.

In addition, the present invention can be applied to the lifting of the groundwater pumping pipe or the heart pump which is sometimes dropped inside the groundwater well using the present invention. In this case, the power is first supplied to the lighting lamp installed in the lower portion of the water pipe and the groundwater heart pump through the camera. While observing the inside, a small and thin lifting device was inserted into the pumping pipe or into the discharge pump pipe, and then the fluid was supplied to the expansion tube to expand the expansion tube to fix the inner circumferential surface of the pump or cardiac pump to the expansion tube. After carrying out the lifting procedure, it can be easily lifted to the outside.

Second Embodiment

Excavation bits or excavation rods dropped during the excavation of groundwater wells, and pump pipes or pumps dropped during the operation of groundwater wells are all circular in shape with a slightly smaller diameter than the inner diameter of groundwater wells.

The present invention is to provide an expansion tube that can be inflated in the inner periphery of the cylindrical tube in a state in which the inner diameter of the cylindrical tube is larger than the diameter of the dropping material.

The expansion tube is fixed by attaching a circular plate ring to the inner and outer circumferences of the expansion tube and the inner and outer circumferences of the lifting tube after attaching the upper and lower ends of the inner circumference of the cylindrical tube to the inner tube. It was made.

In addition, the expansion tube was turned over to the outer periphery of the water pipe body to be fixed with a plate-shaped tightening ring or tube band.

Circular plate rings were machined with female threads or holes for bolting or riveting.

The cylindrical tubular body was formed with an incision in the up and down direction to reach the upper end. The fluid injection tube was internally installed at the incision and welded to draw out the upper part of the lifting device.

In addition, the upper outer periphery was provided with a socket to allow the extension pipe to be connected to hold the lifting device, and on the other side to connect the hook for hanging the lifting wire rope.

In addition, the expansion tube can be covered with a protective tube to prevent accidental damage to the surface while approaching the dropping material, and to facilitate the entry of the dropping material lying on the groundwater at an angle to the inside of the cylindrical tube. The ends were finished with a slightly conical funnel.

The present invention thus achieved,

When the fallout accident occurred in the groundwater well, the groundwater heart well inner wall 35 and the shape of the fallen water, and the depth of the dropout are located by the endoscope camera specially designed to identify the primary groundwater heart well. The lifting device is lowered into the groundwater well.

Intermittently rotating while applying force to the extension pipe while reaching the depth where the dropping material is located, the lifting device is set to be covered with the dropping material deeply to the desired position.

In this case, when the lifting device is enlarged, it may be replaced by a lifting wire rope without connecting the extension pipe. In this case, the lifting device may be set at a desired position by repeating the lifting and lowering several times.

Check whether the lifting device is set on the dropout through the endoscope camera for the groundwater core point, and inflate the expansion tube by injecting compressed air or compressed fluid through the fluid injection tube. As the expansion tube is expanded, the expansion tube is pushed forward with a strong pressure on the outer circumferential surface. In this case, when the expansion tube is lengthened or formed in a multi-layer, the compression fixing effect of the expansion tube on the dropping material may be further increased. In this case, when the dropping material is a heavy object, the expansion tube can be cured in the compressed and compressed state by using a fastening cement or a fluid capable of obtaining the same effect. As a result, the lifting device is held in the solidified state according to the protruding portion of the dropping material so that a stable lifting can be achieved.

Third Embodiment

Excavation bits or excavation rods dropped during the excavation of groundwater wells, and pump pipes or pumps dropped during the operation of groundwater wells are all circular in shape with a slightly smaller diameter than the inner diameter of groundwater wells.

Therefore, the present invention is to form a cylindrical body smaller than the inner diameter of the groundwater core diameter, but larger diameter than these dropouts, but when pulled from the outside to the inner periphery of the cylindrical body to expand the knot noose to be tightened in the form of a knot unfolded in the ring It was installed. In addition, by making the length between the upper and lower ends of the cylindrical tube extremely short, it is possible to form a knot noose in this place by making a ring type.

In addition, the knot noose was configured to be a double or triple knot noose in the form before pulling.

On the inner circumferential surface of the cylindrical tube, a single-layered ring cylindrical tube is inserted.The inner circumferential surface of the cylindrical tube has a ∪-shaped cut line lying on both sides to form a loop. Each required point of the can be fixed.

The wire rope for the knot noose was configured to be drawn out through a fixed link at the top of the cylindrical tube.

In addition, the single-ply ring cylindrical tube can be firmly joined to the cylindrical tube by welding, such that the separation is not made.

In addition, after processing a small hole in the cylindrical tube, the spring of Ω type was inserted here and the wire rope knotted noose of the Ω spring was inserted to fix it.

In addition, the upper outer periphery was provided with a socket to allow the extension pipe to be connected to hold the lifting device, and on the other side to connect the hook for hanging the lifting wire rope.

In addition, the cylindrical tube was to be finished in the form of a slightly conical funnel in order to easily enter the dropping material lying on the groundwater obliquely into the cylindrical tube.

In the present invention as described above, the groundwater core well inner wall 35 and the form of the dropping material, and the depth of the dropout is located by a specially designed endoscope camera to identify the primary groundwater well when a dropout accident occurs in the groundwater well. After grasping, the lifting device according to the present invention is lowered into the groundwater core well.

Intermittently rotating while applying force to the extension pipe while reaching the depth where the dropping material is located, the lifting device is set to be covered with the dropping material deeply to the desired position.

In this case, when the lifting device is enlarged, it may be replaced by a lifting wire rope without connecting the extension pipe. In this case, the lifting device may be set at a desired position by repeating the lifting and lowering several times.

After checking whether the lifting device is set on the dropping material through the groundwater endoscope camera, and pulling the lifting wire rope connected to the knot noose while fixing the extension pipe, the knot noose is tightened on the dropping material. If the protrusions are present in the water, the tightening effect becomes higher. In particular, when the spring of the Ω type is inserted, the spring of the Ω type comes out of the cylindrical tube in the tightening process, it is possible to tighten the droppings.

If the lifting wire rope is pulled up after the knot noose is tightened, the knot noose is further tightened due to the load of the dropping material, and the lifting can be easily performed.

Therefore, as in the first embodiment, the second embodiment, and the third embodiment, the first step of photographing the groundwater cardiac endoscope camera for confirming the shape, location, and depth of the dropped object;

A second step of fixing the cylindrical tubular body to the dropping material by compression tightening;

Using the lifting rope for lifting the groundwater core dropping material lifting device made of a third step of lifting the removal to the outside it is possible to achieve a groundwater core dropping material lifting method.

As described above, the groundwater core dropping material lifting device according to the present invention causes problems such as cracking of the grouting section to facilitate the lifting of the existing incasing pipe when the groundwater core well in which the pollution index water is introduced is improved during healing. In addition to simplifying the grouting process, it also facilitates the lifting of the incasing pipe to solve the complexity of the work process and poor filling of the grouting liquid, which is caused by the presence of the incasing pipe in the original restoration of the closed holes.

Groundwater contamination due to these dropouts can be easily lifted in the event of dropping of drilling bit or excavating rod generated during groundwater excavation, or in case of dropping of groundwater pumping pipe or pumping pump generated during operation of groundwater core In addition, it is possible to prevent them from proactively abandoning the excavation work due to these dropouts or preventing the reconstruction of the groundwater core that was in use.
