The present invention relates to a waste film using a guide frame and a construction method thereof. More specifically, the guide frame is vertically integrated with the guide module and the guide module is installed on the undersurface first. Then, the guide module is stacked along the guide frame, The present invention also relates to a method for constructing a glaze film using the guide frame, which is capable of easily and economically forming a waterproof layer.

FIGS. 1A and 1B are views for explaining a construction method of a conventional film.

Conventionally, as shown in FIG. 1A, a conventional method for constructing a floating film is a method in which a plurality of sheet files are assembled into a circle on the ground, the assembly is transported to a construction site at sea, .

Specifically, an assembly of a plurality of sheet files is formed, and the assembly is transported to an installation position while maintaining the assembled shape

A template 31 in which a plurality of sheet-like supporting members 32 are integrally formed and a plurality of sheet piles 10 are coupled and supported on the outside of the supporting member 32 is manufactured .

As shown in FIG. 1B, the sheet is transported by a sea crane (not shown), is lowered to a construction site, and the sheet file 10 is driven by using an auxiliary crane or the like so that the lower end of the sheet file 10 is fixed to the ground .

In this case, the suspension structure 30 is pulled up by a crane, and another fastening ring is installed inside the head portion of the sheet file again. Thus, the deformation of the sheet file due to the removal of the temporary structure during the in- .

Thus, as shown in FIG. 1B, sand blocks 6 and the like are put into the sheet pile by sand filling input lines 5 or the like to construct a plurality of continuous parchment walls and surround the inner space. It is possible to construct the sea structure.

As a result, this method can be regarded as a method of using the sheet file 10 in the temporary structure 30 for the construction of the gravel film.

1C is a view showing a method of constructing a garbage compartment by connecting the circular pipe members 1 and 3 up and down instead of using the conventional sheet pile 10. Fig.

That is, the lower end of the lower circular pipe member 1 is inserted into the sea floor,

The upper circular pipe member 3 is connected to the upper surface of the lower circular pipe member 1 by water,

The internal seawater is pumped into a dry environment,

It can be seen that the marine structures 11 and 12 are being constructed, and the lower circular pipe member 1 and the upper circular pipe member 3 are finally disassembled.

However, since the connection between the lower circular pipe member 1 and the upper circular pipe member 3 is made in water as shown in FIG. 1D, 1d, the pipe connecting member 20 is separately connected to each other,

The pipe connecting member 20 is welded to the upper peripheral surface of the lower circular pipe member 1,

It can be seen that the lower end of the upper circular pipe member 3 is inserted and connected to the pipe connecting member 20 by the waterproof material P. [

At this time, the pipe connecting member 20 is fixed to the upper circular pipe member 3 with bolts and nuts.

However, when welding, fixing bolts and nuts are all carried out in water, it is very difficult to precisely laminate the circular tube members with waves and algae.

Furthermore, in order to completely waterproof the connection parts of the circular steel pipe modules stacked in the vertical direction, there is always a risk that the waterproofing is performed in a high-level work environment such as underwater work by divers.

[Abrasive film using guide frame (100)]

3 is a view showing the construction of the waterproof layer (A) of the parcel 100 using the guide frame 120 of the present invention, FIG. 4 is a view showing the construction of the waterproof layer FIG. 3 is a perspective view of a parasite 100 using the guide frame 120 of the present invention.

Referring to FIG. 2, the immobilizing membrane 100 using the guide frame includes a lower module 110, a guide frame 120, and an upper module 130.

2, the lower module 110 is manufactured by using a steel material so as to have a predetermined diameter on the ground, and is manufactured to have a constant height, so that a part of the parcel 100 Quot; module "

The lower module 110 is provided with a plurality of vertical reinforcing ribs 111 spaced from each other on the inner surface of the circular pipe member to reinforce the pipe so as to effectively resist water pressure,

The upper horizontal extension flange 112 integrally protrudes horizontally and the upper horizontal extension flange 112 is provided with a cask mount 113 made of a rubber material.

The gland 113 is pressed against the bottom surface of the lower horizontal expansion flange 135 of the upper module 130 by a self weight of the upper module 130, .

3, the upper horizontal extension flange 112 is formed as a circular ring-shaped strip along the upper end of the lower module 110, and the waterproof layer A is compressed by the lower module 110 130).

When the lower module 130 is stacked on the upper surface of the upper module 110, the upper surface of the upper surface of the upper surface of the upper surface of the upper surface of the upper surface of the upper surface This is because it is not necessary to vertically and precisely arrange the lower module when the lower module is dismantled and the waterproof layer is secured.

At this time, the upper horizontal expansion flange 112 is supported by the vertical outer ribs 114 formed between the outer circumferential surfaces of the lower module 110 to prevent deformation due to an operating load.

2, the guide frame 120 is fixed to the inner surface of the lower module 110 so as not to interfere with the vertical reinforcement ribs 111. When the lower module 110 is finally mounted on the sea floor, And a horizontal member 122 integrally formed in the form of a horizontal ring along the inner side surface of the vertical member 121. The vertical member 121 is installed vertically upward from the upper surface of the module to the water surface.

At this time, the outer side surface of the vertical member 121 is connected to and fixed to the vertical reinforcing ribs 111 formed on the inner side surface of the lower module 110 by welding or bolt as shown in FIG. 3, It can be seen that the horizontal member 122 is integrated on the inner surface of the member in the form of a circular ring, thereby being able to easily resist the water pressure.

2, the lower end of the vertical member 121 is formed so that the lower end and the lower end of the lower module 110 coincide with each other, and the lower module 110 ) Extending upwardly from the upper surface of the substrate.

Further, the horizontal member 122 may be formed as a truss member or the like that is vertically spaced apart from one another along the inner surface of the vertical member 121.

As shown in FIGS. 2 and 3, the upper module 130 is formed of a circular tube member which is stacked on the upper surface of the lower module 110.

That is, the upper module 130 is stacked on the upper surface of the lower module 110 to form the final monolayer 100, and the upper module 130 is guided to be stacked on the upper surface of the lower module 110 Can be referred to as a guide frame 120. [

The upper module 130 is stacked on the upper surface of the lower module 110 while descending downward in the water along the guide frame 120 installed in the lower module 110 by its own weight.

That is, conventionally, there is a problem that it is very difficult to set the upper module at a desired position by waves and algae when the upper module is mounted by hanging down on a floating crane in water,

The upper module 130 is stably stacked on the upper surface of the lower module 110 while lowering the upper module 130 along the outer surface of the guide frame 120 by its own weight.

Accordingly, the upper module 130 is manufactured in the same cross-sectional shape as the lower module 110.

In other words, it is made of a circular tube member, and is manufactured in advance on the ground, and is manufactured using a steel plate or the like so as to have a certain diameter,

A plurality of vertical reinforcing ribs 131 may be formed on the inner surface of the upper module 130 so as to be reinforced,

An upper horizontal extension flange 132 is integrally formed at an upper end of the upper horizontal extension flange 132. A cask 133 of a rubber material is also installed on the upper horizontal extension flange 132. [

The upper horizontal expansion flange 132 is formed in the form of a circular strip along the upper end of the upper module 130 so that the upper horizontal expansion flange 132 can easily secure a waterproof layer by press- And the gaps 133 may be required when two or more upper modules 130 are stacked.

3, a vertical outer rib 134 is formed between the circular pipe members on the bottom surface of the upper horizontal expansion flange 132 so that the gland 113 installed on the lower module 110 can be pressed by its own weight, It is noted that a lower horizontal expansion flange 135 is additionally formed on the bottom surface of the vertical outer rib 134.

The bottom surface of the lower horizontal expansion flange 135 of the upper module 130 contacts the upper surface of the gland 113 of the lower module 110 so that the waterproof layer A is formed in a manner .

In addition, even when the lower module 130 is stacked on the upper surface of the upper module 110 according to the upper surface area, the gaps 133 can not be vertically and vertically arranged due to waves, tides, etc., To absorb some degree of the same.

At this time, the upper module 130 may be formed of at least one circular tube member, but it may be divided into two or more according to the depth of water, so that the upper module 130 is formed to have a gland 133 for forming a waterproof layer, Modules can be made without these gaps.

4, for example, one lower module 110, a guide frame 120, and two upper modules 130 are stacked on top of each other to form a parcel 100, and the lower module 100 It can be seen that the waterproof layer A is naturally formed at the connection portion between the upper module 130 and the upper module 130 and the upper module 130 by the adhesive layers 113 and 133.

The upper and lower modules 110 and 130 are formed with vertical reinforcing ribs 111 and 131. The vertical reinforcing ribs 111 and 131 are connected to the vertical member 121 constituting the guide frame 120, The guide frame 120 can be used as an inner reinforcing member of the upper and lower modules 110 and 130. [

In other words, unexpected waves, tides, etc. may occur in the water, so that the upper and lower modules 110 and 130 function as a frame for reinforcing the guide frame 120, thereby enabling construction of the cauldron 100 in the safe water.

[Method for constructing a false film (100) using a guide frame]

FIGS. 5A, 5B, and 5C illustrate a construction flowchart of a fragile film using the guide frame of the present invention.

First, as shown in FIG. 5A, the shredded membrane 100 using the above-described guide frame is produced on land.

The upper and lower modules 130 and 130 include a guide frame 120 integrated with the lower module 110 and an upper module 130 to be stacked on the lower module 110, Or two or more modules.

In the case of FIG. 5A, the upper module 130 is divided into two, but one or more than three modules may be provided, which will be determined in consideration of manufacturing, transportation, mounting, and depth of water.

The lower module 110 is formed as a circular pipe member to be reinforced by the vertical reinforcing ribs 111. The upper horizontal expansion flange 112 is formed in the shape of a circular ring at the upper end, It can be seen that a gland 113 is formed on the upper surface and a vertical outer rib 114 is formed between the circular tube member and the bottom of the upper horizontal expansion flange 112.

At this time, a guide frame 120 is integrally formed on the inner surface of the lower module 110. When the upper end of the guide frame 120 is mounted on the bottom of the sea floor, It can be seen that the steel material 121 and the plurality of horizontal steel materials 122 are integrally formed.

Further, the upper module 130 is formed as a circular pipe member having the same height as each other and is reinforced by the vertical reinforcing ribs 131. At the upper and lower ends, the upper and lower horizontal expansion flanges 132 and 115 are formed in the shape of a circular ring And a vertical outer rib 134 is formed on the circular pipe member between the bottom surface and the upper surface of the upper and lower horizontal expansion flanges 132 and 135. [ As shown in FIG.

5B, a parapet 100 composed of a lower module 110 and an upper module 130 integrally integrated with a guide frame 120 manufactured on the land is hoisted and loaded on a barge, To the position where the construction is to be installed, and then installs the deodorizing membrane 100 using the guide frame.

First, the lower module 110 integrated with the guide frame 120 shipped on the barge is lifted first, and then the lower module 110 is mounted on the sea floor.

At this time, the upper end of the guide frame 120 is exposed above the water surface, and the lower module 110 is located in the water.

It may be installed so as to be penetrated down to the bottom of the sea floor by a method such as a vibration hammer or suction to the bottom surface G of the lower module 110.

In this case, the guide frame 120 is positioned in the water when the exposed upper end is excluded, and is stably installed by the lower module 110.

Further, the upper module 130 is lowered into the water by lifting the upper module 130 from the barge line so that the upper end of the guide frame 120 is located on the inner side of the circular pipe member, And the upper and lower layers are stacked while being lowered along the guide frame 120 on the upper surface.

The gland 113 installed in the lower module 110 is compressed by the lower horizontal expansion flange 135 of the upper module 130 and the waterproof layer A is naturally formed at the connection site.

When the upper module 130 is finally stacked, the upper module 130 is stacked so that the upper module 130 is exposed to the water surface. In FIG. 5B, two upper modules 130 are stacked on the lower module. Is formed.

Next, as shown in FIG. 5C, the upper module 130 and the guide frame 120 are fixedly connected to each other, and the inner water is drained to the outside.

That is, since the upper module 130 is lowered by the guide frame 120 and the waterproof layer is formed, the upper module 130 is mounted on the guide frame 120 using bolts or the like So that the reinforcing operation for sufficiently securing the resistance performance against waves, algae, etc. is achieved.

At this time, if the positions of the vertical members of the guide frame and the vertical reinforcing ribs 111 and 131 of the lower module and upper module are shifted in plan, the upper module may be slightly rotated when the module is mounted on the lower module.

Accordingly, the parabolic membrane 100 is completed, and the seawater and the like in the parabolic membrane 100 are drained to the outside by a pumping operation so that a dry operation can be performed. In the dry state, for example, Etc.).

When the substructure B is completed, the parasitic membrane 100 is disassembled and reusable, and the upper end of the substructure B is exposed above the water surface.

Accordingly, the present invention can precisely control the position of the upper and lower modules at the time of installing the seawater, so that the fragrance film can be completed quickly and accurately,

Since the formation of the waterproof layer at the connection part of the upper and lower modules and the upper modules can be easily performed only by the operation of the upper module, it is possible to form the waterproof layer easily so that it is unnecessary to carry out the high risk of underwater work, And the guide frame is fixed to the upper and lower modules during use after installation at the sea so that the structural safety of the large debris film can be improved by utilizing it as an internal reinforcement.

It will be understood by those skilled in the art that the foregoing description of the present invention is for illustrative purposes only and that those of ordinary skill in the art can readily understand that various changes and modifications may be made without departing from the spirit or essential characteristics of the present invention. will be. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
