The present invention relates to a method for constructing a filter sandstone using a sandstone bag to prevent scouring of the ground during construction of a revetment of a harbor and a seawall. More specifically, in order to prevent ground scour, the dredged soil for laying the ground in the lake is lost by installing a rock stone-sized floor protective stone at the bottom of 2m and installing a filter seat on the inner protective surface of the building. The method of constructing filter seats for floor protection seats using the sandbags when constructing harbor shelter and embankment to prevent the loss of sand due to the flow rate by installing sandstone bags using cranes and poles when installing filter seats Relates to a device.

Conventionally, a bottom mat is formed on the bottom to install a harbor revetment and a seawall, and then a rock-seat size stone is dropped on the upper surface thereof, and then a floor protective stone is installed on the top surface of the sea. Earthenware was used to build a shelter or tidal flat.

Looking at the existing method of construction of the dike construction method, by dumping a large-diameter sandstone, such as rock, on the bottom of the sea, laminating the small-diameter sandstone on top of it, and constructing the dike on the side of the seashore or reservoir on the side of the revetment formed on the inside An order sheet was formed to form an order layer. In this way, when the seawall was built, a water sheet was installed on the water storage side to prevent the loss of sandstone and earth and sand from the water storage side to the sea side.

As described above, there is no problem in installing the order sheet on the part exposed to the sea when constructing the shelter or harbor shore, but the floor protector located at the bottom of the water uses a large diameter stone, such as rock, As the water moves to the sea side, a large hole is formed between the sandstone and the sandstone, so that the flow rate is rapidly progressed by acting like a venturi. In this case, if the flow velocity is not blocked, the dredged soil that is dumped when the revetment is made inside the embankment is lost, and the amount of diesel oil that is dumped through the small-diameter sand to install the filter sand is largely lost. There was a problem in that the construction cost is increased due to the length of the installation period, and the loss of the repellent is produced by scrubbing the built repellent.

That is, in the prior art, in order to form a filter seat at the bottom protective stone end of the bottom surface coinciding with the inner surface of the water repellent on the water storage side, a dump truck of Φ100 mm or less is loaded on a barge and moved to the sea position, and then the excavator is positioned at the designated position by GPS. It has been constructed by dropping the filter seats in the water by design specifications and gradients, etc., but there was a problem that the seats could not be dropped in place due to the flow rate and were lost.

In addition, if you look at the structure of the commonly built dike, in the reclaimed land reclaimed in order to protect the farmland from the sea, it takes 50 ~ 70% of the construction cost before reclaimed land becomes the lifeline of the reclaimed land. Festive ships are selected to minimize the dike extension per unit area in consideration of the elevation of the ground and the level, the tide, the wind direction, and the drainage system of adjacent areas.

The structure of the seawall depends on the condition of the ground, reclaimed scale, wind, algae, festival materials, construction methods, etc., but the types of seawalls that are commonly implemented are as follows.

① The land is the main body, and the front surface is formed with a steep slope, and it is protected by a stone shaft.

② The main body is filled with soil, and the front side is made with a gentle slope and protected with feldspar.

③ It is basic to build steep slopes and cover the back to prevent leakage.

In addition, the height of the levee is 4-5 m higher than the average tide of the group, and the width is at least 1.8 m, usually 3-4 m, and at most 6 m. Since the safety of the dike depends on the size of the bearing capacity of the foundation, the construction method is investigated and the construction method is the existing method of constructing the dike. The foundation is based on the surrounding rock stones and dumped with aggregate such as soil or gravel. There was a problem with the loss of aggregate.

The present invention has been made in view of the above problems, by constructing a filter seat by installing a number of sandbag bags using a crane and a pole on one side of the bottom protection seat on the water storage side when constructing the embankment, when dumping dredged soil for landfill on the water storage side The purpose is to prevent the loss of gravel and soil due to the flow rate, and another purpose is to form a sandstone bag to form a filter sandstone using cranes and poles to simplify the work and shorten the air. It is for the purpose.

The present invention having such a purpose forms a stone bag containing a stone, and formed a pole having a shackle and a steel hook to carry the stone bag to hang a large number of stone bags on the steel hook of the pole to filter the filter seat with a crane It is intended to be installed.

The filter seats installed as above are installed at the location specified in the design without loss of the seats due to the flow rate, and at the same time, the construction period of the filter seats can be shortened. It is to provide a method and apparatus for the construction of filter seats.

Hereinafter, an embodiment of the present invention will be described in detail.

Installing a bottom mat in a conventional manner to form a base at a position to build a harbor shelter and a seawall;

Installing a floor protective stone having a large diameter such as rock stone on the bottom mat of the base plate to a thickness of 2 m;

In the step of building a shelter for laminating the carcass seat on top of the floor protective seat, forming the seating stone on the sea side, and the order sheet is installed on the water storage side,

Installing a primary sandstone bag by using a crane and a pole on one side of the bottom protective stone of the bottom surface of the water reservoir;

Installing the nonwoven sheet to expand by using a diver so as to correspond to the first four stone bags;

Stacking secondary sandbags using cranes and poles on one side of the unwoven sheet and installing filter seats such that the nonwoven sheet installed by using a diver is covered with secondary sandstone bags;

After installing the sea protection stone at a predetermined distance so as to correspond to one side of the filter seat covered with the non-woven sheet is made of a construction step to evenly flatten the top surface of the seawall.

The non-woven sheet is composed of two sheets, one sheet corresponds to the first four stone bags, and the other sheet corresponds to the secondary stone bag outer surface is formed by the step of forming a filter sand stone so that the secondary stone bag is coated.

Referring to the filter seats factory plant for installing the sand bags are as follows.

A steel pipe 11 having a predetermined length and a plurality of reinforcing pieces 12 welded to the outer circumferential surface thereof;

A plurality of shackles 13 installed on the reinforcing pieces 12 on the upper side so as to be connected to the wire rope 21 of the crane 20;

 The shackle 13 is installed on the reinforcing piece 12 on the vertical line of the lower end is provided is composed of a pole (10) formed with a plurality of steel hooks 14 to walk the sand bag (5).

The filter seat construction method and the filter seat factory plant of the present invention configured as described above will be described in detail.

Step 1: Install the Bottom Mat for the Base

A bottom mat is installed on the bottom in a conventional manner in order to form the base 2 at a position to build a harbor shelter and a seawall.

The bottom mat is installed on the bottom of the water at the position where the seawall (1) or the harbor revetment is installed, and the bottom mat is generally selected so that the base can be formed by selecting one of various materials such as a wire mesh, a synthetic resin net, and a concrete structure. How to install

The bottom mat may be installed or not according to the environment and geological structure of the area where the scavenger is installed. In the case of a rock area with a hard bottom structure, it is not necessary to install the bottom mat. Place the pile so that the base (2) is formed.

Step 2: install the protective paving stone

After the base 2 is formed by using the bottom mat, a bottom protective stone 3 having a large diameter, such as rock, is installed on the top of the base at a height of 2 m.

If the floor protection stone 3 is usually formed 2m high and the width is set in accordance with the site conditions of the masonry installation structure, both sides in the longitudinal direction is constructed to be made of a predetermined inclined surface.

In addition, the floor protection stone (3) uses a size that is the same size as the rock stone to use the size that is not lost when dropped in water.

   Third Step: Constructing Embankment

When the bottom protective seat 3 is completed in the second step, stacking the dead body seat on the top.

At this time, the body of the embankment is designed in consideration of the effect of the embankment shape and the body permeability coefficient on the body leakage, and is constructed using the sandstone of the specification specified in the design.

As such, the embankment is constructed by the body of the dead body to form a multi-sloped inclined surface on the sea side, and to form a coated stone with a stone stone having a predetermined size on the outer surface, a straight inclined surface on the water storage side made of order sheets or concrete The order wall is formed, and the outer surface is constructed with sand, etc. to form the order layer.

Forming a layer on the reservoir side when constructing the revetment and the revetment of the harbor prevents the loss and scour of the repellent in the process of moving water to the sea side in the case of the repellent and prevents it and forms the port as a landfill To prevent the loss of sediment when dumping dredged soil.

Fourth Step: Install the Primary Stone Bag

After installing the bottom protective seat 3, the first aiding method is constructed by the construction method of the first step to the third step, and at the same time, the water-repellent side or the bottom side of the bottom protective seat 3 of the harbor shelter in the harbor, Fig. 1 to Fig. As shown in 2b, the filter seat 4 is installed.

The built-up floor protector (3) is in the state of water and the size of the dead stone is a large hole is formed between the stone and the stone because the size of the stone used a large diameter stone, such as a rock stone to form a hole. The hole formed as described above acts like a venturi tube, so that the flow rate is fast, so that the sand of Φ100 mm or less is lost immediately after being dropped, and is not installed at the position where the filter seat 4 is to be installed.

Therefore, in the present invention, the stiffener of Φ100 mm or less is placed in the sack-shaped sandbag bag 5 and installed at the position where the filter seat 4 is installed.

In more detail,

First, to form a lifting pole (10) to be moved by lifting the sandbag bag (5), the pole 10 is made of a circular steel pipe (11) and 8 at equal intervals on the outer peripheral surface to prevent bending of the steel pipe (11) Two reinforcing pieces 12 were welded in the longitudinal direction.

Since the reinforcing pieces 12 are welded so as to be in line with the central axis on the outer circumferential surface of the steel pipe 11, eight pieces are installed at a 45 degree angle on the outer circumferential surface of the steel pipe 11. The reinforcing pieces installed on the outer circumferential surface of the steel pipe are installed so as to prevent warpage from occurring during transfer of the sandstone bag, but may be slightly different depending on the strength of the steel pipe.

 After installing a plurality of steel reinforcing pieces 12 on the outer circumferential surface of the steel pipe 11 as described above, the shackle to be connected to the outer wire rope 21 of the crane 20 to the reinforcing pieces 12 installed on the upper vertical line Install 13, but shackle 13 is formed on the center and both sides for safety to form three (see Figs. 5 and 6).

The number of the shackles 13 is not necessarily limited to three, but when installed only on two sides, there is a problem that the weight of the four stone bags (5) is concentrated in the center. It is preferable that the length of the steel pipe 11 forming 10 is 10 m, and the shackle 13 is provided in three places of the center and both ends of the center.

After the plurality of shackles 13 are installed on the reinforcing pieces 12 welded to the upper part as described above, the reinforcing pieces 12 located on the bottom surface of the steel pipe 11 positioned on the vertical line with the reinforcing pieces 12 provided with the shackles. ) A number of steel hooks (14) to be installed so that you can walk on the sand bag (5).

Since the steel hooks 14 installed on the steel reinforcing pieces positioned on the bottom face are formed with the length of the steel pipe 11 to 10 m, 10 steel rods are installed in a method of installing one per m.

The steel hook 14 may be fixed by welding to the reinforcing piece 12 or may be fixed by riveting or bolts.

In addition, the hook shape of the steel hook is formed so as not to fall off when the seat bag (5) is installed so that it is easy to detach the seat bag strap from the steel hook.

In addition, as another embodiment of the present invention, as shown in Figure 8, the steel pipe 11 is provided with a plurality of shackles 13 to install one reinforcing piece 12 in the upper and lower portions on the vertical line of the upper and lower outer peripheral surface, respectively, and to connect the wire rope to the upper reinforcing piece ), And a plurality of steel hooks 14 can be formed on the reinforcing piece 12 of the bottom surface so that the sandbag bag 5 can be walked.

When installing the shackle and steel hook directly without installing the reinforcing piece in the steel pipe is to assume the condition that the bending does not occur when moving the sand bag back using a strong steel pipe.

When the pole is completed to install the stone bag as described above, after loading the stone bag (5), the pole (10) loaded with the crane (20) and the dead stone on the barge (30), the bottom protective stone (3), filter seat ( 4) Move to the location to install.

Of course, the filter seat (4) position and the position of the barge 30 can be selected by using a GPS, the position can be specified by surveying as necessary to work.

When the device for installing the sandbag bag 5 is prepared as described above, the bottom portion is connected to the wire rope 21 of the crane 20 and the shackle 13 installed at the upper reinforcing piece 12 of the crane 20 as shown in FIG. Hanging the stone bag (5) on the steel hook 14 located in the crane 20 is lifted up to install the 10 stone bags (5) in the filter seat 4 position.

At this time, the diver part 40 is submerged to send a signal to the crane driver so that the filter seat position on the seat bag (5) accurately.

The sandstone bag is made of a size of 67cm in height in an area of 100cm in all directions as shown in FIG. 7, and the upper end of the strap is made of PP rope so as not to be lost in the flow rate.

The shape of the dead stone bag 5 may be formed in various forms such as a circle, a square, an ellipse, a triangle, and a polygon.

Therefore, the seats constituting the filter seats are placed in the bottom 10 using a crane, and then the first seating bag is installed by stacking 10 seats 5 along the inclined surface on the top thereof.

At this time, the primary sandstone bag is installed to extend along the length of the embankment or harbor shore.

Step 5: install the nonwoven sheet

After the first stepping stone bag 5 is installed in the fourth step, the nonwoven sheet 6 is installed so as to be spread on one surface of the stone bag 5, that is, on one surface of the stone bag 5 on the reservoir side. At this time, the non-woven sheet (6) is to be laid on the bottom, and then unfolded to correspond to one side of the first four stone bags installed, and then install the other end with a margin.

The nonwoven sheet 6 is installed by the diver 40 because it is made in the water of the sea. The reason for installing the nonwoven sheet 6 after installing the primary sandbag bag in the present invention is that when the nonwoven sheet 6 is installed to be in direct contact with the bottom protective seat 3, the bottom protective seat 3 by the flow rate. Since the corresponding nonwoven sheet 6 is torn, it is preferable to install the primary sandstone bag so that the nonwoven sheet is spread on one surface thereof.

Step 6: Install the Second Stone Bag

After the 4th and 5th step of the work process, the first bag and the nonwoven sheet are installed, and then the second bag is installed in the same way as the fourth step. Installed on it. Secondary stone bag is also installed on the base to correspond to the primary stone bag, and then install the secondary stone bag to be stacked along the inclined surface on the top as shown in Figures 2a and 2b. As described above, after installing the secondary sack bag (5) to the height of the primary sack bag, the upper spare end of the installed nonwoven sheet (5) is covered so that the secondary sack bag is covered so that the upper part corresponds to the lower part laid on the floor. When the bottom protective seat 3 is made to correspond to the upper surface, the filter seat 4 is completed.

Step 7: finish packing

After the filter seat is installed on the bottom protective seat on the water storage side as described above, the top surface of the embankment or harbor shelter is packed after flattening.

As described above, when the paving work of the seawall is finished, the dredged soil is dumped in order to form a site on the reservoir side.

At this time, as the reservoir side is buried, the water is drained through the floor protection stone, and the soil and the fine aggregate are filtered by the filter stone, thereby preventing the loss of the soil.

In addition, as another embodiment of the present invention, the filter seat may be installed on the floor protection stone when the embankment is constructed, but if necessary, the filter seat is constructed as a sandstone during the construction of the embankment, and the primary sandstone bag is installed on the surface of the embankment on the reservoir side. After the nonwoven sheet is installed, the secondary sandstone bag can be installed again, and a silicide can be constructed by forming a soil layer on the outer surface of the secondary sandstone bag.

The present invention made as described above can be installed in the embankment or harbor revetment without installing a separate order wall when constructing the embankment by installing a filter seat on the body surface during the construction of the embankment.
