Description

Waterproofing structure for repairing of underwater construction

The present invention relates to a clam structure for the repair of underwater construction, and has a prefabricated structure that can be extended to the upper and lower plural layers to facilitate length adjustment according to the repair position, in particular the seams that appear inevitably by adopting such a prefabricated structure Of course, the present invention relates to a clam structure for repairing aquatic structures that defines a safer and more comfortable working space by sufficiently preventing a gap that may occur more than 5 cm between the clam structure and the bottom and side walls of the underwater structure.

Breakwater is a structure to keep the harbor quiet by preventing the waves from the sea. Dams are used to store water in mountain valleys or streams. It is a structure made to prevent the outflow of soil, water intake, rise of water level or collapse. The levee restricts the water of rivers, coasts, lakes and swamps to a certain flow path. It is a civil engineering structure built with earth and sand to prevent flooding and protect coasts and harbors from storms, tidal waves and waves.

All of these underwater structures are installed upright from the bottom of the water, and are generally constructed of special concretes that are resistant to water and flame, and at least one hydrology for controlling flow is divided in the water. However, since these underwater structures are always in contact with water, phenomena such as corrosion and dropping frequently appear, and in particular, they appear intensified in the water part where water is discharged at a high flow rate.

Therefore, for the repair of underwater structures, the working environment of the atmospheric environment where people and equipment can be accommodated should be created in the water. The simplest is to open the gate to expose all the stored water and then repair and repair it. Proceed. However, this is a waste of precious water, considering the reality of Korea, one of the nations lacking water.

Therefore, a water barrier structure is installed upright from the bottom of the water and is tightly fixed so as to surround a part of the inner wall of the breakwater. It will make up.

However, since the inner walls and bottom surfaces of underwater constructions, such as breakwaters, have bad flatness, a large amount of water can flow through the gap with the clam structure. Therefore, in order to prevent this, the existing waterproofing method takes divers to take risks. Entering into the soil, or a piece of wood or using a separate sealing material to prevent the gaps one by one bar, a lot of work time is required, costs are large and dangerous disadvantages.

In addition, the waterproofing method of the existing cladding structure which is dependent on manual operation is low in reliability, so that water is frequently introduced into the working environment during repair work, and this always carries a risk.

In order to solve this problem, there was introduced a clam structure such as the Republic of Korea Registered Utility Model Publication No. 20-0323105, a perspective view thereof is shown in FIG.

As shown, the existing clamper structure is composed of an arcuate body 10 having one side open to the top surface and the breakwater and a bottom surface 11 formed thereon, and a ring 12 for lifting is formed at its upper end, respectively. have. And water blocking index rubber 13 is installed up and down along the ends of both sides facing the breakwater, the bracket 14 is provided with a plurality of brackets 14 each provided with a bolt insertion hole (14a) inside the bar, bracket (14) As the bolt is fastened to the sidewall of the breakwater, the water-resistant rubber 13 is tightly fixed to the breakwater.

Although the cladding structure of the structure as described above is somewhat advanced compared to the existing, if the depth is different from each other depending on the repair position, it is difficult to install simply and easily in the field, because it is necessary to separate the different cladding structures of different lengths, in particular, Considering that a gap of 5 cm or more may be formed between the inner walls of the concrete, there is a problem in that the waterproof structure that depends entirely on the index rubber 13 is very weak.

In addition, the bottom surface 11 is formed, so that it is impossible to repair the floor, such as a breakwater, there was a problem that is difficult to be widely used according to various restrictions.

The present invention is to solve the problems as described above, has a prefabricated structure that can be extended to the upper and lower plural layers to facilitate the length adjustment according to the repair position, in particular the seam portion of the seam that appears inevitably by adopting such a prefabricated structure It is an object of the present invention to provide a water barrier structure for repairing an underwater construction, which sufficiently defines a working space by preventing a gap more than 5 cm between the structure and the bottom and the sidewall of the construction.

In order to achieve the above object, the present invention provides a top surface exposed to the atmosphere in a water barrier structure for repairing underwater structures fixedly installed on the sidewalls of a breakwater, a dam, or an embankment to define a working space of the atmospheric environment therein.

Referring to the state of use of the present invention in detail as follows.

First, the arc-shaped main frame 102 is obtained underwater and seated in the corresponding position, and then interposed between the first buffer bar 110a of the synthetic resin to cover the seam between the bottom 2 and the side wall 4 of the underwater construction. Then, the first sheet 120a of synthetic resin is covered and covered along the first buffer bar 110a, and one edge thereof is tightly fixed along the bottom and side edges of the main frame 102, and the other edge is underwater. It is fixed tightly along the bottom 2 and the side wall 4 of the.

In this case, the first flange 130a may protrude outwardly along the bottom and side edges of the main frame 102 for easier operation. Therefore, the first buffer bar 110a is underwater with the first flange 130a. It is interposed between the bottom 2 and the side wall 4 of the construction.

And one edge of the first sheet (120a) is seated on the first flange (130a) a plurality of first bolts (150a) and overlaps the first guide frame (140a) through all of them A plurality of first nuts 152a may be fastened to each other, and the other edge of the first sheet 120b may be seated on the bottom 2 and the side walls 4 of the underwater construction, and then the second guide frame may be disposed thereon. 140b) is superimposed and fixed using a plurality of screws 160.

Via 110b.

In this case, the second flange 130b may protrude outward along at least the upper edge of the lower main frame 102b for preventing the flow of the second buffer bar 110b and for fixing the second sheet 120b to be described later. As a result, the second buffer bar 110b is interposed between the first flange 130a at the lower end of the upper mainframe 102a and the second flange 130b at the upper end of the lower mainframe 102b.

After covering the second buffer bar 110b with the second sheet 120b of synthetic resin, one edge of the second sheet 120b is tightly fixed along the lower end of the upper mainframe 102a and the other edge of the lower main Along the top of the frame 120b is to be fixed closely.

At this time, the third guide frame (140c) and all of them are superimposed along the first flange (130a) at the bottom of the upper mainframe (102a) with one edge thereof in between for fixing the second sheet (120b) A plurality of second bolts 150b penetrating therethrough and a plurality of second nuts 152b fastened thereto may be used, and likewise, an upper end of the lower main frame 102b with the other edge of the second sheet 120b interposed therebetween. A fourth guide frame (140d) that is nested below it along the second flange (130b) and a plurality of third bolts (150c) penetrating all of them and a plurality of third nuts (152c) fastened thereto. have.

The height can be adjusted, and after constructing a watertight structure 100 that can be completely waterproof, the internal water is discharged to form a working environment of the atmospheric environment.

And it is possible to repair and repair the side wall and the bottom of the underwater construction by introducing equipment and labor into the interior.

Such, the clasp structure 100 is upright from the bottom (2) to define the working space (S) of the atmospheric environment therein, the main frame 102 is installed fixed along the side wall (4) of the underwater construction of the breakwater, dam or embankment It includes a lower surface to be seated on the bottom (2) and the upper surface exposed to the air is open respectively, and one side toward the underwater construction side wall (4) is also open so that the ends of both sides along the underwater construction side wall (4) It has an arc shape in close contact. The inner working environment (S) is isolated from the underwater environment because it forms a shape surrounding the bottom (2) and the side wall (4), its longitudinal section may have a rectangular shape as shown, but depending on the purpose, semicircle, triangular or More polygons can be formed, and in particular, it can have various forms as long as it can stand up from the bottom 2 along the side wall 4 of the underwater construction to define the workspace S of the atmosphere environment therein.

The mainframe 102 has a waterproof structure which is a feature of the present invention so that water does not flow into the mainframe 102, which covers a seam portion between the mainframe 102 and the bottom 2 and the side wall 4 of the underwater construction. The first buffer bar 110a of the synthetic resin, and the first sheet 120a of the synthetic resin covering the outside of the main frame 102, the bottom (2) and the side wall (4), respectively.

First, the first buffer bar 110a covers all the seam portions through which external water can flow, such as between the bottom and side ends of the main frame 102 and the bottom 2 and the side walls 4 of the underwater construction. As the first sheet 120a is covered, in particular, one edge of the first sheet 120a is tightly fixed along the bottom and side edges of the mainframe 102 and the other edge is the bottom 2 of the underwater construction. It is closely fixed along the side wall 4.

Therefore, the water pressure applied from the outside is dispersed by the first buffer bar (110a) and at the same time is covered by the first seat 120a to cover the interior work space (S) of the main frame 102 is separated from the water in the water outside, To this end, the first buffer bar 110a may be made of wood or iron, but preferably synthetic resins such as foamed urethane, foamed polystyrene, foamed polypropylene, and synthetic rubber having a predetermined elasticity may be used. 120a may be a synthetic resin sheet of a waterproof material such as PVC, polyvinyl chloride, polypropylene, and the like.

That is, the first buffer bar (110a) and the first sheet (120a), which is a sealing member that plays a key role in the waterproof structure according to the present invention, regardless of the material that can function as a buffer and waterproof, respectively, but the price In view of the ease of operation and the like, a synthetic resin that is light and easy to process is preferable, and the water that flows into the gap between them while dispersing the water pressure by covering the seam where the water can be introduced by the first buffer bar 110a. It has a structure covered by the first sheet 120a. Therefore, it effectively blocks external water pressure and enables reliable waterproofing.

In this case, a predetermined fixing member may be used to easily fix the first sheet 120a. As an example, the first flange 130a protrudes outwardly along the bottom and side edges of the main frame 102. , The first guide frame 140a overlapped along the first flange 130a with one edge of the first sheet 120a interposed therebetween, and the other side of the first sheet 120a with the underwater guided body therebetween. And a second guide frame 140b nested along the bottom 2 and the side wall 4.

And fixing means for tightly binding the first flange (130a) and the first guide frame (140a), for example, one edge of the first sheet (120a) and the first guide frame (140a) from the first flange (130a) A plurality of first bolts 150a and a plurality of first nuts 152a fastened to each other, and the other edges of the first sheet 120a and the second guide frame 140b are formed at the bottom 2 of the underwater construction. ) And a number of screws 160 may be used for tight coupling to the side wall 4. In this case, the plurality of screws 160 may be replaced with anchor bolts protruding from the bottom 2 and the side wall 4 of the underwater construction. Therefore, by using these fixing members, the first sheet 120a can be closely bound to the respective portions.

At this time, the interval between each of the first bolt 150a and the screw 160 may be properly adjusted for reliable waterproofing, and a separate packing (not shown) made of a material such as rubber may be interposed for a more tight coupling. It may be.

On the other hand, the other clasp structure according to the present invention is characterized in that it can have a prefabricated structure connected to the upper and lower plural layers to be variously applied to the repair position of the different depths, with respect to this in Figure 4 C This will be described with reference to FIG. 5B, which is an enlarged view of the inside drawing. In this case, the main frame 102 may be provided in an upper layer and a lower layer, respectively, and may be connected to a plurality of layers.

In particular, in addition to the first flange 130a protruding outward along the bottom edges of the upper and lower mainframes 102a and 102b, the second flange 130b may protrude outward along at least the upper edge of the lower mainframe 102b. Can be.

In addition, the third and fourth flanges 130c and 130d may protrude inwards along upper and lower ends of the upper and lower mainframes 102a and 102b to tightly fix the upper and lower mainframes 102a and 102b.

Therefore, when connecting the upper and lower mainframes (102a, 102b) up and down, the third and fourth flanges (130c, 130d) overlapping each other can be properly fastened by a bolt and a nut, etc., and can be connected in a solid structure up and down.

However, since water may flow into the seam portion between the upper and lower mainframes 102a and 102b, a waterproof structure is needed to prevent this, which may adopt a structure similar to that described above.

That is, a seam appears between the first flange 130a at the bottom of the upper mainframe 102a and the second flange 130b at the top of the lower mainframe 102b, respectively, between the upper and lower mainframes 102a and 102b. After the second buffer bar 110b of the synthetic resin is interposed between the first flange 130a and the second flange 130b of the upper and lower mainframes 102a and 102b, the outer surface thereof is formed by the second sheet 120b of the synthetic resin. By covering and fixing both edges of the second sheet (120b) along the lower edge of the upper main frame (102a) and the upper edge of the lower main frame (102b), it can be waterproof.

At this time, one edge of the second sheet 120b is positioned above the first flange 130a protruding outward to the lower end of the upper mainframe 102a in order to close and fix the second sheet 120b more conveniently. After covering 140c, at least one or more second bolts 150b sequentially passing through the edge of the first flange 130a, the second sheet 120b, and the third guide frame 140c, and the second fastened to the first flange 130a. The nut 152b may be tightly fixed, and the other edge of the second sheet 120b may be positioned at the bottom of the second flange 130b protruding outward to the top of the lower mainframe 102b and then along the bottom thereof. At least one third bolt 150c covering the guide frame 140d and sequentially passing through the other edge of the second flange 130b and the second sheet 120b and the fourth guide frame 140d and coupled thereto. Close contact with the third nut 152c Can.

In each of these cases, the distance between the second bolt 150b and the third bolt 150c may be appropriately selected for waterproofing as before, and a separate packing having elasticity such as rubber is interposed therebetween. Of course it can be.

Therefore, the clamshell structure according to the present invention connects the at least one mainframe 102a or 102b to the upper and lower plural layers according to the repair position of the underwater construction, between the seams between them and the bottom 2 and the sidewall 4 of the underwater construction. The first and second buffer bars 110a and 110b are interposed on the joints of the first and second sheets 120a and 120b, respectively, to cover and fix them. At this time, the second buffer bar 110a and the second sheet 120b may also be made of the same material as the first buffer bar 110a and the first sheet 120a.

The water barrier structure according to the present invention described above is waterproofed firmly through the buffer bars (110a, 110b) and the seats (120a, 120b) covering the sealing member eventually covering the seam.

As such, when the water barrier structure of the present invention is used, the flatness of the bottom and sidewalls of the underwater construction is extremely poor, so that even if a gap of 5 cm or more is generated, it is possible to reliably waterproof. It is effective to secure a safe workspace.

In addition, the clamshell structure according to the present invention can be easily installed by fastening bolts / nuts using a guide frame overlapping the flanges to secure both sides edges of the seats, and thus, divers may take risks. There is no need.

This makes it possible to implement a safe workspace by providing a simple and reliable waterproof.
