The present invention relates to a ground surface protection wall grouting packer device and a grouting method for preventing the inflow of groundwater contaminated groundwater, and more specifically, to prevent the leakage of grouting materials in the grouting process for the formation of the ground surface protection wall. The present invention relates to a grouting packer configured to be coupled to a ground surface and a method for grouting the subsurface protective wall using the same. In other words, by securing the same inner diameter as the grouting casing, the external shrinkage tube and the inner shrinkage tube are configured so that they can slide or contract with each other while preventing the installation of underground water core internal facilities such as internal well materials and deep water submersible pumps. Cylindrical rubber tube made of rubber material freely flexed on the outer circumferential surface of the outer tube is connected to the top of the outer tube and the lower tube of the inner tube using a tube band. Sliding is generated to create a contraction in the vertical height direction. As a result, the rubber tubes installed in the grouting packer on the narrow groundwater core wall are overlapped and pressed together so that the shielding between the core wall and the packer is shielded. will be. Through this invention, in the case of the device using the expansion tube by the conventional compressed air injection, grouting can solve the difficulties such as the rupture accident caused by the frictional impact with the groundwater core wall or the adjustment of the compressed air injection pressure. In the process, the development of a device and a method for blocking the outflow of the grouting liquid into the groundwater well was completed, thereby greatly improving the quality and reliability of the product.

Groundwater refers to water that fills or fills the gaps between underground layers and rocks, and is contaminated with soil as the industrialization progresses in modern times and the pollution of the soil becomes serious. Groundwater formed by passing through is also a trend that the pollution rate is increasing day by day. The strata are generally composed of soil layers composed of general soil and sand, weathered rock layers with a high permeability of groundwater, and soft rocks, ordinary rocks, and hard rocks. The rock aquifer groundwater formed in the sub-layer of soft rock is not affected by the contaminated groundwater from the soil layer or weathered rock layer in the upper strata, thus maintaining a clear and clean water quality. However, the soil layer and weathered rock layer may be able to perform some filtration function from various contaminants coming from the surface of the earth. The situation arises. Naturally, in the groundwater development process, the soil layer and the weathered rock layer are perforated, and the perforated sections are formed through the soft rock layer, the common rock, and the hard rock layer. As a result, groundwater that is vulnerable or contaminated is contaminated with rock water that is naturally uncontaminated without any resistance or filtration, and has been a major factor in rock aquifer groundwater contamination. Therefore, how to protect the groundwater in the rock aquifer from the contaminated upper groundwater and block the inflow during the groundwater development process is the main purpose and research project so far.

Moreover, in recent years, interest in clean drinking water has increased due to rising income levels and increased outdoor leisure and travel, and the absolute amount of the requirement is supplied through rock groundwater.

On the other hand, the groundwater pollution problem is becoming an important social problem due to various accidents caused by groundwater pollution. Therefore, the seriousness of social repercussions and the rise of groundwater pollution rate have a stronger need for the development of groundwater pollution prevention technology. In addition to the increasing research on the devices and methods for developing uncontaminated groundwater, the groundwater development process must be planned or enforced through legislation. It is expected that it is approaching to this point.

Accordingly, the necessity of the emergence of universal technology that anyone can easily and easily install and construct can be said to be inevitable.

In order to solve the grouting problem of the groundwater core, the inventors have already applied for and registered a number of patents and utility models other than Patent No. 0334451 (Patent name: grouting pipe apparatus and grouting method of groundwater core) and successful technical integration in the field. It has been contributing to the national groundwater development and pollution prevention related fields by accomplishing commercialization. The grouting packer using the expansion tube developed by the inventor can secure high shielding at various intervals between the groundwater core wall and the outer circumferential surface of the grouting casing. In addition to being listed in the guidelines, in the case of Jeju Island, the enforcement of special laws is enforced. However, as described above, in order to inflate the expansion tube, compressed air is required to be inflated, and the grouting thickness prescribed by the groundwater method is required in the process of inserting the grouting casing up to a depth of 30 meters or less from the surface. There was a problem that there was always a possibility that the gap, which is less than 50 mm (mm), could be ruptured by friction and impact with the narrow groundwater core wall. In addition, due to the vertical installation, the expansion tube is injected with water to expand the hydrostatic pressure (approximately 1.033 kg / square centimeter pressure per 10 meters of water). There is a problem that it is difficult to adjust or secure the pressure, so compressed air is used to solve this inconvenience.The pressure of the compressed air is that the expansion tube starts to expand even at 0.1 kg / cm or more due to its high expandability. Since the proper supply air pressure must be determined considering the head pressure in the depth minus the groundwater level, beginners who are new to the device have difficulty in supplying it, and supply it directly to the groundwater developer who focuses more on the task than the theory. In the process of construction, It confirmed that the solution was difficult to adapt to the field, and for this reason, it had to be limited to broader technical applications.

In addition, Patent No. 10-0715746 (Patent name; grouting device for preventing groundwater well contamination and its construction method) has invented a device and a construction method for constructing a surface underpass protection wall to prevent the surface water contaminated into the groundwater well. However, this apparatus and method are mounted on the annular fixing plate and the fixing plate upper surface to shield the lower surface of the gap between the in- casing and the out-casing, and the separated structures are separated from each other on the outer and outer casing surfaces of the casing. It is composed of a device consisting of the inner packing and the outer packing, and the control means for controlling the separation distance between the inner packing and the outer packing so as to be in close contact. However, the problem of the present invention is that the incasing and groundwater excavation walls used for grouting have a limit that the inner packing and the outer packing may not function in a space where the poles are narrow, and the gap between the incasing and groundwater excavation walls is insufficient. According to the size of the inner packing and the outer packing, the thickness value of the outer packing is often inconvenient to follow the inconvenience, as well as to insert the wedge member, the height of the inner packing and the outer packing has to be limited. As a result, the shielding length is shortened and the shielding area is reduced, which is insufficient to secure effective shielding performance. More importantly, there is no consideration on how to operate the wedge member, which is a control means for controlling the separation distance between the inner packing and the outer packing, in the gap between the in casing and the groundwater drilling pit which are usually narrowed to about 50 millimeters. Have Therefore, there is a problem that is difficult to use the present invention in the industrial site for preventing groundwater contamination.

The present invention to solve the above problems of the prior art,

By securing the same inner diameter as the grouting casing, the external shrinkage tube and the inner shrinkage tube are configured so that they can slide or contract with each other while preventing the installation of underground water well internal facilities such as internal well materials and deep water pumps. The packer device installed with the cylindrical rubber tube 30 made of synthetic resin or rubber material freely flexed on the outer circumferential surface of the pipe is connected to the grouting casing and then installed on the outer circumference of the packer device through strong pressing and indentation from the ground. The inner shrinkage tube slides or contracts to generate contraction in the vertical height direction, and as a result, a rubber tube provided between the packer device between the groundwater deep hole wall and the grouting packer having a narrow gap of about 50 millimeters (mm) (30) ) Are overlapped and pressed together, so the gap between the heart wall and the packer is completely It is to provide a grouting paekka device and the lower surface protection wall grouting method to occur The purpose of the present invention.

Hereinafter, described in detail with reference to the accompanying drawings a preferred embodiment of the present invention for achieving this purpose are as follows.

Ground surface protection wall packer device for preventing groundwater inflow of the upper groundwater wells applied to the present invention is configured as shown in Figures 1 to 10.

In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

The following terms are terms set in consideration of functions in the present invention, which may vary depending on the intention or custom of the producer, and their definitions should be made based on the contents throughout the specification.

First, a feature of the technical configuration of the present invention is to invent a ground surface protective wall grouting packer device for preventing groundwater inflow of the upper layer of the groundwater core well excavated to collect groundwater,

Ground-level protective wall grouting packer for preventing groundwater inflow of the upper layer of groundwater core connected to grouting casing,

A contraction component configured to allow the outer contraction tube and the inner contraction tube to contract vertical height by compression;

A rubber tube which is installed on the outer periphery of the contraction component and overlaps or is pressed in accordance with the contraction of the contraction component to shield the gap between the groundwater core wall and the packer device;

It is characterized in that it consists of a safety support device that supports the contraction component until it is completely inserted into the groundwater core and prevents the contraction from contracting.

Hereinafter, described in detail with reference to the accompanying drawings,

Packer device 17 according to the present invention comprises a shrinkage configuration 11 and the rubber tube (30). The packer device 17 having such a configuration is installed at the periphery of the grouting casing to shield the periphery of the grouting casing or to be connected to a holding rope or the like to be used for closing the groundwater core.
For example, the grouting casing is inserted into the groundwater core well and the upper grouting casing 2 (part of which is filled with grouting material after shielding by the packer 17) is fixed by the lower surface protective wall after shielding by the rubber tube 30. , Ie consisting of a length up to the grouting depth) and a lower inner casing 10 connected to the lower portion of the upper grouting casing 2, the packer device 17 comprising an upper grouting casing 2 and a lower inner casing 10. ) Are coupled between.
The inner contraction tube 12 and the outer contraction tube 14 constituting the contraction configuration 11 may be manufactured by cutting the general pipe by an appropriate length or bending it roundly. In addition, the upper end of the inner shrinkage tube 12 constituting the contraction configuration 11 is bonded to the engaging jaw ring 16 toward the outer circumference and the engaging jaw ring 16 also bonded to the inner circumferential side of the outer contraction tube 14. When the packer device 17 is inserted into the groundwater core well 1 so that the inner shrinkage pipe 12 and the outer shrinkage pipe 14 can be formed to mutually interlock, the packer device 17 itself Lower inner casing 10 connected to the lower portion of the weight or packer device 17 (hole hole casing with a plurality of holes and holeless casing without holes may be combined or hole casing and holeless casing may be configured alone). Packer device 17 is separated by the weight of the was configured to prevent breakage. Here, the perforated casing and the non-perforated casing are casings inserted into the excavated groundwater wells, which are generally composed of synthetic resin or stainless steel pipes 50-50 mm smaller than the diameter of the excavated groundwater wells, and in the case of perforated casings, rock aquifer underground veins The casing is installed by processing holes in the horizontal or vertical direction to facilitate the inflow of groundwater from the groundwater pump to the space where the groundwater pump is installed. The airless casing is a casing in which no holes are processed, such as grouting casing (2). Say. The inner contraction tube 12 of the contraction component 11 is fixed to the upper grouting casing 2 and the outer contraction tube 14 is fixed to the upper end of the lower inner casing 10. This is according to the case where the inner shrinkage tube 12 is disposed above, and the coupling structure is naturally changed when the upper and lower positions of the inner and outer shrinkage tubes 12 and 14 are changed.

Of course, in order to obtain the same effect of shrinkage, the bellows may be used in place of the outer contraction tube 14 or the inner contraction tube 12 or the inner contraction tube 12 and the outer contraction tube 14 together.

In addition, the outer constriction tube 14 is usually located at the bottom of the constriction component 11, but it is also natural that the installation position of the inner constriction tube 12 and the outer constriction tube 14 may be interchanged as necessary. Will do.

At the lower end of the outer shrinkage tube 14, a compression ring 15a processed by a PE rod made of stainless or synthetic resin was formed. In order to fix the outer ring of the outer constriction tube 14, the crimping ring 15a is processed through the outer and inner circumferential surfaces of the bolt hole 67, and fixed to a nut that is welded and fixed to the outer circumferential surface of the outer constriction tube 14 in advance. . The upper inner surface of the pressing ring 15a takes the funnel portion 45 like the inner surface of the circular cup so that the rubber tube 30 overlaps the rubber tube 30 when the contracting portion 11 contracts. By preventing the phenomenon that the pressing ring (15a) is pulled down to be able to guide the upward direction of the overlapping direction of the rubber tube 30 as well as zoom. Of course, the funnel portion 45 may be formed by attaching a separate synthetic resin (PE) plate to form a wide.

The upper end of the inner constriction tube 12 of the contraction configuration 11 was processed by a PE or PE rod made of stainless or synthetic resin to form a pressing ring 15b inserted and fixed along the outer circumferential surface of the inner contraction tube 12. . The compression ring 15b is the compression ring 15b of the rubber tube 30 in the process of overlapping the rubber tube 30 during the contraction of the contraction portion 11, such as the compression ring 15a of the external shrinkage tube 14. It prevents the phenomenon of being pulled upward, and serves to set the limit of the upward direction of the overlap as well as the rubber tube 30. In other words, the outer diameter of the compression ring 15b of the inner shrinkage tube 12 and the compression ring 15a of the outer shrinkage tube 14 is slightly smaller than the inner diameter of the excavated hollow wall 60 of the groundwater core 1 so that the insertion is easy. Make it easy but make the gap as small as possible. When the material of the pressing ring 15b and the pressing ring 15a is made of PE, which is a synthetic resin, in particular, the hardness of the material is relatively weaker than that of the rock of the groundwater core well (1). There will be no difficulty in making it happen.

Two or more guide holes 19 are drilled in the crimping ring 15b to be symmetrical in the same direction as the circumferential direction so that the contracting portion 11 can be integrated with the external shrink tube 14 through the guide holes 19. Guide plate 22 configured to be connected to be guided to operate.

In addition, in order to operate the shrinkage member 11 of the packer device 17 in the absence of a bottom or a latching jaw for the bottom of the packer device 17, the inner shrinkage tube constituting the shrinkage member 11 (12) and the outer shrinkage tube (14) should be made by sliding contraction mutually withdraw the fixed holding rope (40) holding the contraction component 11 to the ground and fixed to insert the upper grouting casing (2) by pressing Or while holding the upper grouting casing 2 fixed, the holding rope 40 is tensioned using a winch or the like so that the contraction component 11 is contracted so that the rubber tube 30 is overlapped and pressed at the same time. The gap between the excavation hole wall 50 and the packer device 17 may be shielded. That is, the holding rope 40 holding the outer shrink tube 14 is pulled out and fixed to the ground, and the upper grouting casing 2 is pressed and inserted or the holding rope 40 is fixed while the upper grouting casing 2 is fixed. When 40 is tensioned using the rotation of the motor, the inner contraction tube 12 is in a fixed state while the outer contraction tube 14 is pulled up while overlapping the rubber tube 30 and simultaneously pressurizes the groundwater. The gap between the excavation hole wall 60 and the packer device 17 of the core well is shielded. At this time, the holding rope 40 is configured to penetrate the rubber tube 30. Due to the characteristics of the soft rubber tube 30, a phenomenon in which a gap is formed due to the holding rope 40 is not generated. This function results in the same effect as fixing the lower part of the packer device 17 to the floor and actuating the contracting portion 11.

In addition, the height of the outer contraction tube 14 connected to the pressing ring 15a of the outer contraction tube 14 does not significantly affect the function of the packer device 17, but does not interfere with the independence of the guide plate 22. If it is a form, it will not interfere.

In addition, the contraction of the contraction component 11 is generated by a strong compression on the ground or by using a compression force using a self-compression spring, so that the rubber tube 30 is contracted in the vertical height direction to compress the stress on the ground. When it is removed or the compression force of the compression spring is reduced by the self-resilience of the rubber tube 30, the stopper 100 is configured to prevent the rise in the direction in which the contraction structure 11 is restored. The stopper 100 may be installed in various forms. For example, when the contraction is made by forming a triangular engaging jaw 29 having a right triangle shape having an inclined portion and a jaw on a vertical surface of the guide plate 22. In this case, the contraction is made without a jamming phenomenon, but after the contraction is completed, even if the pressing force for the contraction is removed, it may be configured not to be restored again by being caught by the triangular catching jaw 29 (see FIGS. 2 and 3). Of course, the triangular catching jaw 29 is installed on the guide plate 22, as shown in FIGS. 15 to 18, and the deployment part 42 and the protrusion 41 which partially cut the lower end of the inner shrinkage tube 12 to a narrow width. ) And a perforated portion 43 in a vertical direction in a line so that the protrusion 41 can be inserted in the inner circumferential surface of the outer shrinkage tube 14. When the contraction portion 41 is inserted into the perforation portion 43 may implement the same effect to make it difficult to restore and various other methods may be used.

In addition, the outer contraction tube 14 and the inner contraction tube 12 may not necessarily be a hard material, and may be a folding type, not a separate structure.

The rubber tube 30 is installed in the form of a cylindrical body, the rubber tube 30 is installed in the form of a cylindrical body, and the rubber tube 30 is installed in the form of a cylindrical body. When the contraction component 11 is contracted, it is formed to be long enough to obtain the effect of overlapping, so that the contraction component 11 is contracted so that a conventional grouting thickness of 50 mm can be shielded through the effect of multilayer overlap. Sufficient thickness was ensured. In addition, the material is to be manufactured using silicon rubber so that even after a long time does not adversely affect the groundwater quality even in the final component decomposition process.

The upper portion of the rubber tube 30 is covered with a separate water-expanded rubber band 50 (see FIGS. 4 and 6), and the shield is further further shielded by the expansion of the water-expanded rubber band 50 even when the shielding is made. You can make your performance double. Of course, the entire material of the rubber tube 30 can be used as a water-expandable rubber material. The rubber tube 30 is fixed to the tube band 51 is usually made of a stainless band, the bottom of the rubber tube 30 is fixed to the bottom of the outer contraction tube 14 of the shrinkage configuration (11) The upper end of the rubber tube 30 is fixed to the upper end of the inner shrinkage tube (12).

The rubber tube 30 may be wrinkled in order to maximize the overlapping effect of the multilayer according to the shrinkage of the contraction component 11, or the thick portion 53 (shown in FIG. 10) may be a rubber tube 30. Formed on the outer periphery, the shielding effect is maximized by overlapping, and as a result, the shielding of the excavation hole wall 60 and the packer device 17 of the groundwater core well is completely achieved. In addition, by installing a fixing band 55 (shown in FIG. 11), such as a plastic 0 ring, in the middle of the rubber tube 30, it is possible to obtain a boundary effect of the overlapping surface. By forming and configuring the hemispherical thick portion 53, the effect can be enhanced.

The thick portion 53 of the rubber tube 30 may be composed of one or a plurality. In particular, when the gap between the excavation hole wall 60 of the groundwater core well and the upper grouting casing 2 is wide, in order to shield it, the overlapping length of the rubber tube 30 is increased and the number of overlapping is increased so that it is a multi-layered structure. The overall length of the tube 30 should be long and at this time, the number of installation of the thick portion 53 will have to be increased. In addition, the thick portion 53 may use a soft rubber material, but by using a hard rubber material, the thick portion 53 may act as a boundary of the overlapping limit of the rubber tube 30 as a function of the fixing band 55. .

Of course, the same shielding effect may be obtained by inserting a plurality of donut-shaped rubber 0 rings through the outer periphery of the outer shrink tube 14 and shrinking the contracting portion 11. Also, the rubber tube 30 may be obtained. It can be regarded as a kind of. As shown in Fig. 12, the donut-shaped rubber 0 ring is composed of an inner rubber 0 ring 70 having a small outer diameter and an outer rubber 0 ring 71 having an inner diameter slightly smaller than the outer diameter of the inner rubber 0 ring 70 and having a shrinkage component. When the installation is inserted into the outer shrink tube 14 of the (11) by inserting the alternating order, the inner rubber 0 ring 70 is the outer rubber 0 ring (71) when the contraction component 11 is contracted As it is inserted into the outer rubber 0 ring 71, the outer diameter of the outer rubber 0 ring 71 is further increased. Shielding of the core drilling hole wall 60 and the packer device 17 can be made completely.

The rubber tube 30 is manufactured by using soft silicone rubber or soft non-toxic synthetic rubber so that it does not adversely affect the groundwater quality even in the final component decomposition process.

In addition, when the rubber tube 30 is made of a water-expandable rubber material having a property of expanding when absorbing water, the rubber tube 30 is compressed and contracted and fixed, and the rubber tube 30 is absorbed and expanded to absorb water more strongly. The groundwater core drilling hole wall 60 and the packer device 17 may be shielded by pressing the gap, which may further double the effect of shielding.

In addition, when the rubber tube 30 is ruptured in the process of overlapping the rubber tube 30 in accordance with the contraction of the contraction component 11 or in the process of inserting the packer device 17 into the groundwater core 1. Although the contraction component 11 is in a state in which the contraction is completed, there may be a concern that the grouting liquid injected may be introduced into the groundwater core 1 through the ruptured point of the overlapped rubber tube 30. In order to solve such a problem, the rubber tube 30 was installed inside the leakage protection tube 80 (see FIG. 5) having a strong function against friction or impact. Leakage protection tube 80 is made of fiber or synthetic resin material (PE) film that does not affect the water quality. Of course, the grouting material is introduced into the groundwater core 1 during sliding by inserting a rubber 0 ring 101 (shown in FIG. 19) between the inner and outer shrinkage pipes 12 and 14. It can also be prevented.

In addition, as shown in FIG. 19, the rubber tube 30 should be completely shielded the groundwater core drilling hole wall 60 and the packer device 17. Groundwater core drilling hole wall 60 is made of rock and is equipped with a hammer bit The groundwater core excavation pit wall 60 formed by the hammer bit in the process of excavating the groundwater core well (1) using an excavation equipment is not finished with a smooth surface, but is generally finished with a rough surface like a millstone surface. The rock joint layer 82 having a large gap is formed so that the shape of the excavated vacant wall of the exact round shape is not formed, and the recessed gap space portion 83 is formed. In order to shield such irregular and rough surfaces, the effect of the overlapping of the rubber tube 30 due to the compression of the contracting member 11 and the entry of the gap space 83 due to the softness of the rubber tube 30 can be easily achieved. It should be possible to secure full and even pressure. Through this application it is possible to prevent the inflow of leakage into the groundwater core (1) inside the routing material such as cement liquid through the fine gap space portion 83.

In addition, the outer side of the rubber tube 30 was installed to cover the protective cover 84 (see Fig. 13, 19) made of a separate fiber material. The protective cover 84 is made of a cylindrical shape having a sufficient outer diameter because there is no expandability in the nature of the material, but the portion to cover and fix the packer device 17 to form a corrugation (85) to be fixed by a band. The protective cover 84 suppresses the phenomenon that the soft rubber tube 30 is pushed out only in a certain direction due to the soft rubber characteristics by being compressed during the shrinking of the contracting portion 11, thereby making it evenly overlapped and compressed. This is because the protective cover 84 is not expandable, as described above, because no external protrusion than the diameter of the original diameter is made.

Through such a configuration, the gap between the groundwater deep drilling hole wall 60 and the packer device 17 has a thickness and length of the rubber tube 30 ranging from about 10 millimeters to about 100 millimeters, and a boundary forming an overlapping boundary. According to the quantity of the band 55 or the thick portion 53, it is possible to express the effect of ensuring a complete shielding by the rubber tube (30).

In the upper part of the pressing ring 15b, the packer device 17 connected to the upper grouting casing 2 connected to the upper grouting casing 2 is rubbed or caught by the excavation hole wall 60 of the groundwater core 1 in the installation process of the packer device 17. There is a high possibility that the contraction component 11 can be contracted regardless of the operator's intention by its own weight or pressing force. At this time, the contraction component 11 is supported to prevent the contraction component 11 from contracting. The safety support device is configured to function to allow shrinkage by the operation of a.

The safety support device is composed of a locking plate 26, a safety pin 24, and a pull line 25, as shown in Figs. Here, the locking plate 26 and the safety pin 24 is a locking portion for restraining the contraction of the contraction component 11, the pull line 25 is an operation unit for operating the safety pin 24.

The locking plate 26 is made of a thick stainless steel plate of about 5mm and the safety pin hole 33 for the safety pin 24 is processed.

The safety pin 24 may be understood to be similar to the structure or principle of the safety pin installed in a conventional fire extinguisher or grenades, and the pull line 25 is a safety pin installed in the packer device 17 which is usually installed at a depth of 20 to 30 meters from the ground surface. To connect 24) from the safety pin 24 so that it can be operated on the ground, stainless wire is usually used as a string installed to extend to the ground. Further, in the process of inserting the packer device 17 and the upper grouting casing 2 into the groundwater core 1, a pull line 25 is sandwiched between the groundwater core drilling hole wall 60 and the upper grouting casing 2. In order to prevent the situation of the wrong pull pull string 25 was installed to be inserted into a separate protective hose (35).

The safety pin 24 is configured to have a function of fixing the pressing plate 15b of the locking plate 26 and the inner shrinkage tube 12. That is, when the safety pin hole 33, which is processed in the locking plate 26, is inserted into the crimp ring 15b and the safety pin hole 36, the open leg portion 27 of the safety pin 24 is connected to the crimp ring 15b. If the safety pin hole (36) is caught and is not pulled strongly the safety pin (24) will be securely positioned. At this time, the guide plate 22 of the outer contraction tube 14 is in a state in which the triangular inclined portion 23 extends to the guide hole 19 formed in the crimping ring 15b and is inserted into the guide hole 19. If the locking plate 26 is rotated so that the center of the guide hole 19 and the guide plate 22 is in a straight line, the guide plate 22 is inserted through the guide hole 19 without any resistance. It comes up. Due to this configuration, when the pull wire 25 connected to the safety pin 24 is pulled from the ground, the safety pin 24 is detached from the safety pin hole 33 of the locking plate 26 and the pressing ring 15b and the guide plate ( The locking plate 26 spanning the triangular inclined portion 23 of the 22 is naturally rotated on the one hand while the guide plate 22 is raised through the guide hole 19 while the contracting portion 11 is contracted. As the holding force suppressing the disappearance disappears, the contraction of the contraction component 11 is made. That is, the inner contraction tube 12 is lowered by the guide of the guide plate 22 fixed to the outer contraction tube 14 while the rubber tube 30 is pressed strongly and takes the form of overlapping sequentially. As a result, the gap between the groundwater deep drilling hole wall 60 and the packer device 17 is completely shielded. The support jaw 28 formed at the upper end of the crimping ring 15b serves to support the lock plate 26 so as not to escape to the outside, and the tension spring (not shown) is connected to the lock plate 26 and the support jaw ( By connecting to one end of 28) even if the locking plate 28 is slightly moved by the triangular jaw (29) to be able to return to the original position again.

Of course, the safety support device by processing the safety pin hole between the inner contraction tube 12 and the outer contraction tube 14 of the contraction configuration 11 while connecting the pull line 25 through the upper grouting casing (2) It is also possible to install and to change the design to a variety of structures to ensure the same functionality of course.

In addition, the safety pin 24 is detached in a state where the locking plate 26 is fixed to the upper grouting casing 2 and the guide plate 22 of the outer shrink tube 14 is in the flat portion of the locking plate 26. While pressing the upper grouting casing 2 while rotating slightly in a constant direction (usually clockwise), the guide plate 22 protrudes through the guide hole 19 and consequently contracts the contraction component 11. Tube 30 is overlapped to obtain a shielding effect. At this time, the inner shrinkage tube 12 constituting the contraction portion 11 is fixed to the bottom, the bottom is fixed, even if the upper grouting casing (2) is rotated simultaneously with the upper grouting casing (2) occurs Will not be. Of course, if there is a promise part for the function in advance, only the rotation direction of the upper grouting casing (2) without the safety pin 24 is installed to release the support of the safety support device and the contracting portion 11 The same effect can be obtained for shrinkage.

In addition, it can be configured to operate the safety support device by operating the electric operation switch on the ground by using the normal electric power, that is, the electromagnet or the electric motor, etc. This principle is the principle of the operation of the locking and unlocking of the general automatic door If you configure it by application it will be possible.

In addition, a limit switch (not shown) having a conventional sensor function or the like is attached to an upper circumferential surface of the upper grouting casing 2 applied by the upper end of the contracting portion 11 or the guide plate 22, thereby completing contraction to a predetermined height or less. It may be possible to check the contraction state of the contraction component 11 as a light signal from the ground step by step. Of course, by installing a separate identification sensor (not shown) such as a proximity sensor at the bottom of the inner shrinkage tube (12) and the bottom of the outer shrinkage tube (14) to receive a signal or by the introduction of the underwater camera of the packer device 17 It may be possible to check the normal operation.

In addition, a spring 31 is provided between the pressing ring 15b and the pressing ring 15a of the contracting portion 11 or between the pressing ring 15b and the guide plate 22 of the outer shrinkage tube 14. It is also possible to support a certain form in the transport, storage, insertion process of the packer device 17. Of course, the cylindrical tubular rubber tube 30 may function to maintain a certain shape, but due to the nature of the soft silicone rubber, the external contraction of the shrinkage member 11 in the state that the packer device 17 cannot bear its own weight Since the pipe 14 and the inner shrinkage pipe 12 are not held in a fixed position, there is a high possibility of causing a breakdown of the safety support device due to the occurrence of noise and frequent shocks and separations that occur during transportation. Prevention was possible.

Of course, while constructing the contraction component 11, the strong tension spring (90) (see Fig. 21) is tensioned by using a mechanical force and secured using a safety support device and then inserted into the groundwater core well (1) and then installed safety By removing the safety pin 24 of the supporting device, the rubber tube 30 overlaps and compresses automatically by the compression force of the tension spring 90, thereby reducing the gap between the groundwater core drilling hole wall 60 and the packer device 17. It may be configured to be shielded. As an example of such a configuration, the outer contraction tube 14 of the contraction component 11 exists only in the form of a short cylindrical body for fixing the pressing ring 15a and the rubber tube 30, and is tensioned at the top thereof. Spring 90 is installed. On the inner circumferential side of the tension spring 90, the inner shrinkage tube 12 of the contraction component 11 is formed with a sliding gap, and a compression ring 15b is installed at an upper end thereof. The outer circumference of the tension spring 90 is provided with a rubber tube 30 is covered. In the manufacturing process, the tension spring 90 is tensioned by the jig tool, and the safety pin 24 is inserted between the guide plate 22 of the outer shrink tube 14 and the compression ring 15b of the inner shrink tube 12. Supported its form. When the present invention is applied to the closed hole packer for the restoration of the groundwater core well (1), the closed hole packer (92) inserted into the dighole groundwater core well (1) in the support hole 91 is a closed hole packer (92). When the pull wire 25 of the safety pin 24 is strongly and momentarily pulled from the ground due to its own load, the safety pin 24 is removed from the safety support device, and the tension spring 90 pulls the rubber tube 30 with a strong compression force. While pressing, the rubber tube 30 is overlapped and simultaneously pressed to shield the gap between the groundwater deep drilling hole wall 60 and the packer 17.

In general, in such a case, an effective work can be achieved when applied to the packer device 17 for the recovery of the closed park, which does not require the connection configuration of the upper grouting casing 2 to the upper part of the packer device 17.

On the other hand, the present invention may be variously modified and may take various forms in applying the above configuration.

And, it is to be understood that the invention is not limited to the specific forms referred to in the above description, but rather includes all modifications, equivalents, and substitutions within the spirit and scope of the invention as defined by the appended claims. It should be understood as
