Description

Coffering structure with hydraulic pressure or self load}

It relates to a temporary water barrier structure using hydraulic pressure or self-weight. More specifically, in the state of receiving constant water pressure by seawater or fresh water such as a repair structure such as a drainage lock and a bottom surface continuously formed below the repair structure, when a temporary water blocking process is required for the repair and partial new work. For example, the present invention relates to a method of continuously repairing an entire repair structure after installing a box-shaped temporary barrier structure at a part receiving water pressure according to the inner and outer water level of the drainage lock. To solve the inefficient problem caused by installing the temporary barrier structure for the order of the entire repair structure for the repair of the repair structure, and to install more efficient temporary barrier structure by using water pressure or self-weight in the installation It is possible to work and index work, it is structurally safe, it is easy to install and dismantle, it is possible to reuse the temporary barrier structure, and the construction is improved, so that the temporary water barrier using water pressure or self weight can shorten the air and economically work. It is about a structure.

The most important problem in the repair work of the repair structure is that the ordering process by the temporary water barrier work must be performed in order to secure the required dry work environment. That is, in the case of the repair structure 10 including a drainage lock installed in a river estuary in contact with the seawater as shown in FIG. 1, a doorpost 2 supporting the drainage lock 1, a column 3 protruding from the bottom of the door, drainage It includes a retaining wall (4) formed on both sides of the lock and a bottom plate (5) formed to have a predetermined thickness continuously in the lower portion of the repair structure, the rim (3), the retaining wall (4) and the bottom plate (5) In the case of a concrete structure, it is usually submerged in seawater to a predetermined height, and the concrete cover is peeled off under the influence of the scour caused by the waves, and the reinforcing steel is corroded by seawater. . Therefore, in order to repair this, it is inevitable that installation work of ordered means such as temporary barrier structure is required to work without being affected by sea water. One of the means that can be commonly used as a conventional method for the installation of such a means is a temporary water barrier structure such as sheet piles at regular intervals from the repair structure so that the entire repair structure is not affected by sea water. It is possible to think of a method for forming a water repellent means and repairing a damaged repair structure or installing a required structure in a state in which a temporary water barrier is allowed to dry out by pumping seawater inside the structure with a pump.

However, this method is very inefficient. It is very inefficient to install a temporary barrier structure that can be used to fill the entire repair structure economically and in terms of working air. , Large barges, offshore cranes, etc.), and sheet pile members for ordering purposes, which are usually manufactured as steel sheets, are usually installed by anti-taking, which makes them almost impossible to reuse such as damage to the head. Even if the temporary barrier structure is partially installed, the construction is very low, and the problem that it cannot be reused remains as it is, and at present, there is almost no proper method development.

Therefore, it is urgently necessary to develop a temporary water barrier structure and its installation method that can safely and promptly complete work in repairing repair structures in contact with fresh water as well as seawater.

The purpose of the present invention is to provide the overall repair structure without the provision of a temporary cladding structure as a means for covering the entire repair structure. By providing a means to provide a temporary barrier structure using water pressure or self-weight capable of improving the construction properties and shortening the working air of the repair structure temporary barrier installation work.

Another object of the present invention is to support the hydraulic pressure, so that the end of the temporary barrier structure by the hydraulic pressure or self-weight can be installed in contact with the repair structure, by forming an exponent means at the end of the temporary barrier structure in contact with the hydraulic structure It is to provide a temporary water barrier structure using water pressure or self-weight capable of efficient indexing work.

Still another object of the present invention is to provide a temporary water barrier structure using water pressure or self-weight to provide a new index means and a method of installing the same in the temporary water barrier structure.

Still another object of the present invention is to provide a temporary water barrier structure using water pressure or self weight that is reusable and includes an internal reinforcement means for appropriately supporting the water pressure and a separation prevention means for securing safety.

Still another object of the present invention is to provide a temporary water barrier structure using water pressure or self weight, which can support the water pressure of seawater or fresh water, and has a cross section and a shape capable of securing an optimal pressure support structure.

In order to solve the above technical problem, the present invention is in contact with seawater or fresh water, so that the repair structure can be used for repairing the repaired structure, which always has a hydraulic pressure surface. While wrapping in size, the end is installed to be in contact with the hydraulic pressure surface or the support portion formed on the hydraulic structure itself by hydraulic pressure or self-weight, and the watermark can be formed in double at the end to secure the degree perfectly. Reinforcement means to support the water pressure by seawater or fresh water and box-type barrier structure with upper and lower openings installed to prevent the safety of work are installed. When the back is completed, the lifting equipment, such as a small crane mounted on the barge, can be used to The technical feature is that the repair work can be efficiently performed on the entire repair structure by completing the repair work on the entire repair structure by lifting it to a position for repair and the like.

Best Mode for Carrying Out the Invention The best embodiment of the present invention will be described in detail with reference to Figs. 1 to 7, and will be described separately by establishing and repairing a temporary water barrier structure and a repair structure using the same.

<Temporary cladding structure>

The temporary water barrier structure 200 of the present invention has a water pressure surface or a water surface in the structure 100 in which the water pressure surface exists, at a predetermined interval partially around the object structure formed on the water pressure surface. Characterized in close contact with the target structure, it will be described with reference to Figures 2a and 2b.

The hydraulic structure 100 having a water pressure surface is installed at a point where fresh water and sea water meet, and is installed between the door 120 installed at the lower end 110 and the drainage lock 130 which is moved up and down, Regarding the retaining wall 140 constituting both sides of the repair structure in succession with the drainage lock and the bottom plate 150 continuously formed at the lower portion of the drainage lock, the door and the vowel, it will be representative.

The drainage lock 130 is installed between the door 120 as shown in Figure 2a and 2b and moved up and down along the door by a separate lifting device having a seawater opening and closing function of the repair structure, to the seawater The locked part is subjected to water pressure according to the depth, so that the surface of the water pressure always exists. This hydraulic pressure surface corresponds to a portion where the ends of the temporary water barrier structure described later are in close contact with each other.

The retaining wall 140 is constructed at a predetermined height on both sides of the repair structure in succession with the drainage lock 130 to support a ground such as soil on the rear surface of the retaining wall. There is always a hydraulic pressure surface under constant water pressure, and it is also a structure to be covered with water if the concrete covering constituting the surface is damaged.

The door 120 has a function of supporting the drainage lock 130 as a concrete columnar structure. Particularly, the area in contact with seawater is subjected to continuous load (water pressure due to blue) due to waves, etc., so there is a great possibility of damage in concrete coating, and the lower part submerged in seawater also has a lot of room to be scoured by blue, so it has an elliptical cross section. The column 110 is separately installed to distribute the load by the waves so that the door is not in direct contact with the sea water, and it is common to have a scour reinforcement means such as a separate support (121, a kind of haunche) at the lower end. to be. Furthermore, since the nunju formed on the door is almost immersed in seawater, the locked part is always subjected to water pressure, and thus there is always a water pressure surface, and in the case of a damaged jangju, repair work is required to belong to the object structure.

The column 110 is installed in two types, as shown in Figure 2a is formed in the elliptical cross-section at the lower end of the door 120 has a type that is installed with a predetermined height, as shown in Figure 2b the overall shape of Figure 2a. It is similar to the note, but has a form with a separate vertical groove (111, stop log) in the middle. The difference in the shape of the columnar serves as a criterion for determining whether the cross-sectional shape of the temporary water film to be described later to make the cross-sectional shape square or circular.

The bottom plate 150 is a concrete plate having a predetermined thickness in succession with the lower part of the door and the column, and is always locked in the sea water, so that the upper surface is always subjected to hydraulic pressure, so that the surface to be pressurized always exists, and the damaged floor plate In this case, the repair work is required, so the water barrier belongs to the target structure.

In particular, in the case of the column 110, the retaining wall 140 and the bottom plate 150 may be seen as a structure in which the hydraulic surface is present, it can also be seen as a target structure to be repaired or newly established. Because the column, retaining wall and the bottom plate is always in contact with the sea water and the concrete cover is damaged by the waves and belong to the object to be repaired. In the case of the column 110, the retaining wall 140 and the bottom plate 150, if the concrete coating is damaged by the waves caused by sea water, repair it, or in order to form a new structure on the damaged site is called concrete pouring, curing Since it is essential to the process, a dry work environment is required. The means for enabling such dry work is the temporary water barrier structure 200 which functions as the order means.

A schematic installation of the structure of the temporary barrier structure 200 is shown in FIGS. 2A and 2B.

That is, the temporary water barrier structure 200 is installed so that the end is in contact with the drainage lock 130 in which the water pressure surface exists, as shown in Figure 2a, the inner structure of the water blocking object such as the column 110 installed on the door 120 It is installed while wrapping at a predetermined interval from the box-shaped temporary water barrier structure (c) having a c-shaped cross section whose top and bottom sides are opened and closed (Example 1 below),

The retaining wall 140, which has a water pressure surface and is also a target structure, is installed so as to contact the end as shown in FIG. 2A, and is installed while wrapping at a predetermined interval, and has a box shape having a c-shaped cross section in which the upper and lower portions are opened and closed. Temporary barrier structure 200b (hereinafter, specific example 2),

As shown in Figure 2b is also installed so that the end portion is inserted into the vertical groove 111 formed in the column 110, which is a target structure of the water barrier because the surface is a water pressure, and also the water barrier such as the inner column 110 inside It is installed while wrapping a predetermined interval from the target structure, the box-shaped temporary water barrier structure (200c, the specific example 3) having a circular cross-section, the upper and lower opening and closing

2a and 2b are also installed in the seawater because the end surface is in contact with the bottom plate 150, which has a water pressure surface and is also the object structure of the water barrier, and is wrapped around a predetermined interval, the upper and lower The temporary box of a rectangular box shape, which is opened and closed, may be divided into a structure 200d (hereinafter, specific example 4).

The temporary water barrier structure 200 of Embodiments 1 and 2 has a box-shaped temporary water barrier having a c-shaped cross section so that the end shaving of the temporary water barrier structure in contact with the water pressure surface is formed in a vertical plane. The structures 200a and 200b are used,

In the third embodiment, since the temporary barrier structure 200 is a concave portion in which the hydraulic surface is blocked out like a vertical groove 111 formed in the column 110, the end of the temporary barrier structure is inserted into and supported by the vertical groove. When installed so that a box-shaped temporary water barrier structure 200c having a circular cross section which is the most advantageous cross-sectional shape for supporting the hydraulic pressure is used,

Since the temporary water barrier structure 200 of Embodiment 4 has a hydraulic surface formed in a horizontal plane, a rectangular box-shaped temporary water barrier structure 200d is used so that the end shaving of the temporary water barrier structure in contact with the temporary water barrier structure may also be formed in a horizontal plane. There is a difference.

Hereinafter, specific examples 1, 2, 3, and 4 of the temporary water barrier structures 200a, 200b, 200c, and 200d will be described in detail with reference to FIG. 3.

FIG. 3A illustrates a plan view of the box structure, wherein the box structure is a temporary water barrier structure 200 having a c-shaped cross section with upper and lower portions open, and at both ends, a water pressure means 230a is formed. It is installed in close contact with the water pressure of the seawater to the drainage lock 130, which is the repair structure 100 having a surface, and wraps around it with a predetermined distance from the footnote 110 formed on the door 120, which is the target structure of the water barrier. It serves as a sort of order means.

3B is a cross-sectional view of the plate member 210a and the support member 220a forming the outer surface of the box structure. In other words, the plate member constituting the outer surface of the box structure is usually made of a steel plate of a predetermined thickness, and the horizontal support member horizontally installed at predetermined intervals up and down using an I-beam beam inside the plate member 221a and a supporting member 220a including a vertical supporting member 222a vertically installed at a predetermined interval left and right using an I-beam in the horizontal supporting member 221a. have. The material, installation intervals, and whether the support member is installed in the plate member and the support member depend on the design criteria according to the size of the water pressure according to the seawater level, the size of the structure to be covered, and the working environment (wave strength, difference between tides, etc.). It is changed accordingly, while supporting the water pressure by sea water or fresh water, the internal space is a space for dry work.

The water supply means 230a has a function of preventing seawater from flowing into the box structure by using pressure when both ends of the box structure are in close contact with the drainage lock having the hydraulic surface. As shown in FIG. 1, the water supply means 1 231a is formed on the entire end surface of the box structure and the water supply means 2 232a is formed to be inclined to contact the drainage lock from the outside of the end of the box structure.

<New construction and repair method using water barrier structure>

The construction and repairing method of the repair structure using the water barrier structure is a structure in which the hydraulic pressure surface is present by using a lifting device such as a marine crane as a temporary water barrier structure (200a, 200b, 200c, 200d) having a predetermined size and shape or A first step in which the water film formed on the water pressure surface partially wraps around the target structure (arrangement, retaining wall) so that the water pressure surface or water film is in close contact with the object structure by water pressure; And a second step of distilling the water inside the temporary water barrier structure to the outside and newly constructing or repairing the hydraulic pressure surface or the water barrier object structure (speech, retaining wall, and bottom plate).

As the temporary water barrier structure of the present invention, the box structure of Embodiments 1 to 4 described above may be used. That is, in the case of the object structure of the water barrier such as the column 110, where the receiving groove 111 is not formed, a box structure having a cross section of the first embodiment of the first embodiment is manufactured in advance, and in the case of a water structure such as the retaining wall 140, the object structure is formed. The box structure of Embodiment 2 is prepared in advance, and in the case of the target structure of the water barrier such as a column formed with the receiving groove 111, the box structure of Embodiment 3 is prepared in advance, and in the case of the bottom plate 150, Create a rectangular box structure.

At this time, the end face of the box structure of Embodiment 3 is manufactured in a state in which the above-described intermediate member 233c is additionally formed.

Since the box structures of the specific examples 1 to 4 are each formed with lifting means at the upper end, the crane mounted on the barge first to install the manufactured box structure in close contact with the hydraulic pressure surface of the drainage lock, the bottom plate or the retaining wall. Use to move the box structure on the barge, and tow the barge with the tug to move to the final installation position. At this time, it is preferable that the bottom surface of the seawater should be installed at the final position so that the bottom surface is not inclined in either direction when the box structure is installed using a diver.

The loaded box structure is installed by mounting a lifting device such as a crane mounted on a barge at the final installation position by connecting a lifting means formed on the box structure. Once the box structure is installed, the seawater can be pumped out to the outside using a pump to form the interior of the box structure into a dry working environment. At this time, it is checked whether there is seawater penetrating into the box structure by an index means installed at the end of the box structure. In the present invention, since the index means are provided in duplicate, a perfect index is possible.

If the box structure of Embodiments 1, 2 and 4 is installed in close contact with the drainage lock, the bottom plate or the retaining wall, additional reinforcement means and separation prevention means are installed inside the box structure. Furthermore, when the wave is heavy, the heavy material is installed over the box structure to increase the weight of the box structure to prevent the deviation of the position of the box structure.

This allows the worker to repair damaged ferrules and retaining walls using work aids such as circular ladders and work plates installed separately in the box structure, and install new structures as needed.

Furthermore, in the case of installing the cylindrical box structure as in Embodiment 3 in the column formed with the vertical grooves, the box structure is provided after the supporting member 234c such as wood is installed so that the end part is inserted and supported in the vertical groove formed in the column. The end of the primary should be fixed first. Furthermore, the hydraulic jack 235c is installed so that the water discharge means 1 formed at the end portion can be compressed to the side of the vertical groove.

When the repair of repair structure such as an anchor or retaining wall is completed, the reinforcing means or separation prevention means formed in the box structure is dismantled, and the lifting device of the box structure is used to lift the box structure by using the lifting device of the barge. After the connection is lifted up, it is moved to another location or loaded on the barge, and then the barge is moved to a predetermined position, and then installed in a manner of mounting the box structure again. This makes it possible to continuously repair the entire object structure, such as scaffolds, bottom plates and retaining walls.

At this time, if the box structure is made to fit the working air and the number of installations and the number of movements are adjusted, the temporary barrier structure can be installed with minimum production cost. Above all, the box used when the final repair is completed There is an advantage that can be used very economically because the structure can be reused.

The temporary clamshell structure of the present invention is manufactured to the minimum size that can work while supporting the load by hydraulic pressure as much as possible, and it is a box structure with double exponent means installed, which can be safely operated by the worker by additional reinforcement means and prevention of departure. It can be installed in close contact with the water barrier to partially wrap around the target structure by using water pressure, so that the operator can quickly repair or install the repair structure, and can move to the desired position when the work is completed, and reuse is possible. This makes it possible to make temporary barriers faster and more economical.
