[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an embankment construction method and a construction method suitable for constructing a embankment up to a predetermined height to construct a temporary wall body having a temporary wall surface when constructing a retaining wall or the like. A block forming tool used.

[0002]

2. Description of the Related Art Conventionally, in the case of constructing a wall body such as a retaining wall in which a wall surface is formed, a sandbag is installed after the embankment forming portion adjacent to the position where the wall surface is to be formed, in which the embankment is to be formed. By a series of operations such as forming embankment on the side of the sandbag embankment formation, stacking multiple embankments up to the predetermined height of the wall surface to construct a temporary wall body with a temporary wall surface. The temporary wall body is constructed, and concrete is placed on the temporary wall surface of the constructed temporary wall body to construct the wall body in which the wall surface is formed. Further, in order to save labor such as preparation and transportation of sandbags, Japanese Patent Laid-Open No. 5-3
As shown in No. 06523, as a substitute for the sandbag, a tubular bag into which mortar or the like can be injected is prepared, and the bag is laid at a position where a temporary wall surface should be constructed, and the mortar is placed in the laid bag. The embankment method of pouring and forming a mortar block was proposed. Furthermore, when a landslide or the like occurs in the constructed temporary wall body, the landslide is stopped in order to prevent the progress of the landslide so that the landslide does not occur over all of the plurality of embankments stacked above and below that form the temporary wall body. It was necessary to provide a sheet-like reinforcing material such as geotextile.

[0003]

However, in the embankment method of using these sandbags or forming a mortar block as shown in Japanese Patent Laid-Open No. 5-306523, these sandbags and blocks such as mortar blocks are the earth pressure of the embankment. Use a sheet-like reinforcement material that is laid between embankments to prevent the progress of landslides, that is, roll up blocks that are installed or formed on the sheet-like sheet reinforcement material, The planar reinforcement is folded back in the form of a sheet, and the embankment is formed by embedding the portion laid at the tip of the planar reinforcement and the folded-back portion, so that the blocks are wrapped with the planar reinforcement. The block was supported on the embankment via the sheet reinforcement in such a manner that the portion laid in front of the sheet reinforcement and the folded back portion were pressed by the load of the embankment, etc. Work to return Ri had been taken is very troublesome. Moreover, in order to prevent the progress of landslides, it is necessary to lay it between the embankments at appropriate intervals, so that the planar reinforcing material also serves to prevent the sideslip of the block, it is necessary to lay it between all the embankments. In addition, as the size of the sheet-like reinforcing material, an extra width for enclosing the block was required, so not only was it uneconomical because a large amount of sheet-like reinforcing material was consumed, but also the degree of freedom in design was limited. It was Further, when the temporary wall surface of the temporary wall body made of embankment and the concrete to be placed on the temporary wall surface are integrated, the reinforcing bars are inserted into the temporary wall surface of the constructed temporary wall body at a predetermined interval and then the concrete is placed. As a result, they have been integrated through the reinforcing bars, so that it takes time and effort to insert a large number of reinforcing bars into the temporary wall surface of the constructed temporary wall body.

In view of the above circumstances, the present invention provides a embankment method and a construction method which can save labor for constructing a temporary wall body having a temporary wall surface, can be economically constructed, and have a large degree of design freedom. It is an object to provide a block forming tool to be used.

FIG. 8 is a perspective view of an infusion bag, and FIG. 8 is a perspective view of an infusion bag different from the infusion bag shown in FIG. 7.

As shown in FIGS. 4 to 5, the injection bag 10 to which the block forming tool used in the embankment method of the present invention is applied is a tube-shaped foldable and expandable tube made of synthetic resin such as vinyl having a circular cross section. It has a waterproof main body 11, and an injection space 13 into which mortar or the like can be injected is formed in the waterproof main body 11. In addition, as shown in FIG. 4, expansion preventing ribs 12 are provided in the waterproof main body 11 so as to project in a direction (vertical direction in the drawing) orthogonal to the longitudinal direction (horizontal direction in the drawing) of the waterproof main body 11. An injection hole 12a is provided at a substantially central portion of the expansion stop rib 12 so that the expansion stop rib 12 is covered with the waterproof main body 1.

That is, the injection space 13 is provided in the waterproof main body 11 so as to be partitioned by the expansion stop ribs 12 and to communicate the injection spaces 13 with each other through the injection holes 12a. Further, as shown in FIG. 5, the waterproof main body 11 is provided with a laying portion 11a formed in a predetermined laying width D in a band shape along the waterproof main body 11, and the laying portion 11a is laid. The included width D is
The block 5 to be described later is set so that it can be engaged with the embankment 2 to the extent that a resistance force that prevents the block 5 from sliding sideways due to the earth pressure of the embankment 2 can be generated.

Since the injection bag 10 to which the block forming tool used in the embankment method of the present invention is applied is constructed as described above, the wall body 120 having the wall surface 20 is constructed by applying the embankment method of the present invention. If the wall body 120 is
And, as shown in FIG. 2, a plurality of embankments 2 are formed in the embankment formation portion MS.
Is built up to a predetermined building height H, and the temporary wall body 101 in which the temporary wall surface 1 is formed is built up by the following construction procedure. That is, first, as shown in FIG.
The wall surface 20 on which the foundation groove 31 should be built in the ground 40 adjacent to the wall surface building position X1 on which the wall surface 20 of the wall body 120 should be built
Excavated and formed according to the shape of
The foundation 30 is formed by laying 5 in such a manner that the foundation groove 31 is closely packed.

Next, as shown in FIG. 1B, the ground 4 adjacent to the temporary wall surface building position X2 where the temporary wall surface 1 of the temporary wall body 101 adjacent to the formed foundation 30 and the foundation 30 is to be built.
On 0a, a flexible sheet-like reinforcing member 6 made of a sheet of non-woven fabric or the like in which grit-like polypropylene, vinyl or the like such as geotextile, or the like is formed from within the embankment forming portion MS. It is laid along the foundation 30 outside the portion MS (on the left side in the figure) so as to project from the temporary wall surface building position X2. That is, the planar reinforcing material 6 is provided on the foundation 30.
Is laid in such a manner that the engaging portion 6a at the tip of is placed. next,
The injection bag 10 is rolled into a roll or the like and folded to be carried into the temporary wall surface building position X2, and the temporary wall surface 1 is laid on the planar reinforcing material 6 adjacent to the temporary wall surface building position X2 to be built. ,
The infusion bag 10 is laid so as to extend along the foundation 30. At this time, the laying portion 11a of the waterproof main body 11 of the injection bag 10 is laid so as to be arranged in the embankment forming portion MS. Next, a grooved mold 15 having a trapezoidal cross section is installed above the laid infusion bag 10 so as to cover the infusion bag 10. Then, the laying portion 11a of the injection bag 10 is, as shown in FIG.
Laying width D from the installed formwork 15 along the formwork 15
It is in a state of being arranged in the embankment forming portion MS in a form of protruding only. Next, the mortar 9 is poured into the laid laying bag 10 by a pump (not shown) or the like in such a manner that the mortar 9 is densely filled in the respective filling spaces 13 of the filling bag 10. Then, the infusion bag 10 becomes the mold 1
Since it is covered with 5, the mold 15 expands along the shape of the trapezoidal cross section. The injection bag 10 has an injection hole 12a.
Since the expansion stop rib 12 formed with is provided,
The mortar 9 injected into the injection bag 10 is filled into each injection space 13 through the injection hole 12a, but the expansion stopper rib 1
Since 2 restrains the displacement of the injection bag 10 in the radial direction, the injection bag 10 is preferably filled with the mortar 9 without a part of the injection bag 10 expanding and being deformed or damaged. (Of course, if the waterproof main body 11 of the injection bag 10 itself has sufficient strength against expansion due to filling of the mortar 9, it is needless to say that the waterproof main body 11 does not need to be reinforced with the expansion preventing ribs 12 and the like. )

Then, when the mortar 9 filled in each injection space 13 of the injection bag 10 is cured, the mold 15 is removed.
Then, at the temporary wall construction position X2, as shown in FIG. 1C, the form 1 is in close contact with the waterproof main body 11 of the injection bag 10.
A block 5 composed of a mortar 9 molded into a trapezoidal cross section by 5 is installed along the foundation 30. (Note that
The removed formwork 15 is reused. ) Next, at the position adjacent to the block 5, the laying part 11a of the injection bag 10 arranged on the embankment forming part MS side is embedded on the ground 40a on the embankment forming part MS side of the formed block 5. Forms a permeable layer 3 made of a drainage material such as rubble stones. Further, on the right side of the permeable layer 3 in the figure, earth and sand 36 is piled up to the height of the block 5 to form a part of the temporary wall 101. Two embankments 2
To form. Then, the laying portion 11a of the waterproof main body 11 of the injection bag 10 is embedded under the embankment 2, so that the embedded laying portion 11a of the injection bag 10 becomes the earth and sand 3 of the embankment 2.
Since it receives the load of 6 or the like and is mechanically coupled to the earth and sand 36 or the like to engage with the embankment 2, the waterproof main body 11 of the injection bag 10 in which the laying portion 11a is embedded is placed outside the embankment forming portion MS. When it is pulled laterally (leftward in the figure), a resistance force due to engagement with the embankment 2, that is, a predetermined resistance force such as a frictional force due to the load of the embankment 2 or a coupling force due to mechanical coupling is generated. It will be. By the way, the laying portion 11a of the infusion bag 10 is
Since the laying width D of the laying portion 11a is set so as to generate a resistance force that prevents the block 5 from skidding due to the earth pressure of the embankment 2, the block 5 is a waterproof main body of the infusion bag 10. Through the 11, by the resistance force due to the engagement between the laying portion 11a of the waterproof main body 11 of the injection bag 10 and the embankment 2, it is supported so as not to skid toward the outside of the embankment forming portion MS (left side in the figure). To be done. Therefore, even if the embankment 2 is formed in the embankment formation portion MS after the block 5 is formed, the block 5 can reliably hold the earth pressure of the embankment 2 without sliding sideways. In addition, since the block 5 is formed of one infusion bag 10, it is possible to counter the local load of the entire block 5 against the local earth pressure of the embankment 2. It can be formed easily and reliably.

Next, the block 5 thus installed
As shown in FIG. 1 (d), the planar reinforcing material 6 is laid on the (5A) and the embankment 2 (2A) in the above-described manner, and the infusion bag is placed on the laid planar reinforcing material 6. 10 is laid along the block 5 (5A) previously installed. Also, infusion bag 1
The mold 15 removed previously is installed above 0 in a form of supporting the infusion bag 10 as appropriate, and the mortar 9 is injected into the infusion bag 10 in such a manner that the mortar 9 is densely filled in the infusion bag 10. When the mortar 9 filled in the injection bag 10 hardens,
Remove the formwork 15. Then, a new block 5 (5B) having a trapezoidal cross section made of mortar 9 is installed along the top of the block 5 (5A) previously installed, so that it is placed on the embankment 2 (2A) previously formed. The permeable layer 3 is formed at a position adjacent to the block 5 (5B) by burying the laying section 11a of the injection bag 10 arranged on the embankment formation section MS side, and the permeable layer 3 is located on the right side in the figure. New block 5 for earth and sand 36
Fill up to the height of (5B) and fill a new embankment 2 (2B)
To form. At this time, the laying portion 11a of the injection bag 10 is
By being buried under the new embankment 2 (2B),
The new block 5 (5B) also includes the laying portion 11a of the injection bag 10.
And the new embankment 2 (2B) is supported by the resistance force due to the engagement between the embankment 2 and the new embankment 2 (2B).
The new block 5 (5B) can reliably hold the earth pressure of the new embankment 2 (2B) without skidding.

In this way, the block 5 having the laying portion 11a made of the mortar 9 filled in the injection bag 10 while the mold 15 is reused is formed at the position where the temporary wall surface 1 is to be constructed.
After forming the block 5, the embankment work for forming the embankment 2 is repeated to stack the block 5 and the embankment 2 in the vertical direction, and the planar reinforcement is provided between the block 5 and the embankment 2 that are stacked above and below the block 5. 2 (a) by selectively laying the material 6 so as to prevent the progress of landslide between the embankments 2.
As shown in, the temporary wall body 101 in which the temporary wall surface 1 having the building height H is formed is built. In addition, as shown in FIG. 3, the blocks 5 of the temporary wall body 101 are vertically stacked so that the expansion preventing ribs 12 of the injection bag 10 are arranged in a staggered manner.
Further, the surface of the block 5 is formed of the waterproof main body 11 made of vinyl or the like and does not allow the moisture of the embankment 2 to pass through, so that the drain pipe 19 is provided between the stacked blocks 5.
It is provided at a predetermined interval so as to communicate with the water permeable layer 3 for draining water. Furthermore, the planar reinforcing member 6 is used for the constructed temporary wall body 1.
01 when a landslide or the like occurs, the landslide 01
It is provided in order to prevent the progress of landslide so that it does not occur over all of the plurality of stacked embankments 2 that form the ground. Therefore, it is not necessary to provide between all the embankments 2 and 2, and between the embankment 2 where the planar reinforcing material 6 is laid and the embankment 2 where the planar reinforcing material 6 is not laid based on the design condition of the wall body 120 to be constructed. 2 and select, for example, as shown in FIG. 2 (a), the lower embankment 2 which is expected to be subjected to a large earth pressure.
In the upper embankments 2E, 2F, 2G, 2H, 2X, where a planar reinforcing material 6 is laid between all the embankments 2, 2 of A, 2B, 2C, and 2D, the earth pressure is expected to be small. Is
It suffices to selectively lay a required amount of the planar reinforcing material 6 at a desired pitch such as laying the planar reinforcing material 6 only between the embankments 2E, 2F and the embankments 2H, 2X.

Next, when the temporary wall body 101 is constructed, as shown in FIG.
As shown in (b), the engaging portion 6a at the tip of each planar reinforcing member 6 protruding from between the blocks 5 and 5 is laterally provided outside the temporary wall surface 1 of the temporary wall body 101 (on the left side in the drawing). While projecting to the left (in the figure), a drainage hole 21 is provided so as to communicate with the drainage pipe 19 of the temporary wall body 101. To build.
Then, the temporary wall surface 1 of the temporary wall body 101 and the concrete 39 cast on the temporary wall surface 1 are integrated through the engaging portions 6a of the planar reinforcing members 6 protruding from between the blocks 5 and 5. Therefore, unlike the conventional case, the temporary wall surface 1 of the temporary wall body 101 and the temporary wall surface 1 of the temporary wall body 101 are not required to insert many reinforcing bars into the temporary wall surface 1 of the constructed temporary wall body 101.
Since it is possible to integrate the concrete 39 that has been cast into, the integration work can be saved. In addition, when it is not necessary to integrate the temporary wall surface 1 of the temporary wall body 101 and the concrete 39 poured into the temporary wall surface 1, the engaging portion of each planar reinforcing material 6 protruding from between the blocks 5 and 5. Since the engaging portion 6a of each planar reinforcing member 6 is allowed to naturally hang down without positively projecting 6a in the lateral direction (leftward in the drawing), a design change is required for the integration. If it happens, you can deal flexibly.

As described above, the infusion bag 10 is the infusion bag 10
By injecting the mortar 9 into the injecting space 13 of the waterproof main body 11, the block 5 having the laying portion 11a made of the mortar 9 can be formed. In addition, the laying portion 11a formed on the block 5 in this manner is used for the embankment 2.
Since the block 5 can be supported on the embankment 2 via the embedded laying portion 11a so as not to skid, the block 5 can be supported via the planar reinforcing member 6 as in the conventional case. Since it is not necessary to fold the planar reinforcing material 6 one by one to support the embankment 2, the block 5
It is possible to easily prevent the skid of, and it is possible to save labor for constructing the temporary wall body 101 in which the temporary wall surface 1 is formed. Further, the temporary wall surface construction position X at which the temporary wall surface 1 should be constructed
Put the mortar 9 in the pouring bag 10 laid in 2 by a pump or the like.
It is possible to form a continuous block 5 at the temporary wall construction position X2 simply by injecting, so that the temporary wall surface is less labor-intensive than the method of stacking sandbags filled with sand one bag at a time to form an embankment. The labor of constructing the temporary wall body 101 in which No. 1 is formed can be further saved. Further, since the planar reinforcing member 6 may be selectively laid between the embankments 2 so as to prevent the progress of landslide between the embankments 2, all the embankments 2
Since it is not necessary to lay it in between, the degree of freedom in design is widened, and the planar reinforcing material 6 is not wasted, which is economical. Further, since the planar reinforcing material 6 is laid outside the embankment forming portion MS so as to project from the temporary wall surface building position X2, the engaging portion of the planar reinforcing material 6 projecting from the temporary wall surface building position X2. By placing 6a in a suspended state, even if concrete 39 is cast on the temporary wall surface 1 of the constructed temporary wall body 101, the temporary wall surface 1 and the cast concrete 39 are not integrated. The temporary wall body 101 is formed by placing concrete 39 while projecting the engaging portion 6a of the reinforcing member 6 in the lateral direction.
Temporary wall surface 1 and concrete 39 cast on the temporary wall surface 1
Can be integrated via the planar reinforcing members 6. Therefore, since the temporary wall surface 1 of the temporary wall body 101 and the concrete 39 cast on the temporary wall surface 1 can be freely integrated, not only the design change of the integration can be easily dealt with but also the conventional The temporary wall surface 1 of the temporary wall body 101 and the concrete 39 cast on the temporary wall surface 1 are integrated into one body without any trouble such as inserting a large number of reinforcing bars into the temporary wall surface 1 of the temporary wall body 101 thus constructed. Therefore, the integration work can be saved, and the labor for constructing the temporary wall surface 1 of the temporary wall body 101 can be saved. Therefore,
The labor for constructing the temporary wall surface 1 of the temporary wall body 101 can be saved, the construction can be economically performed, and the degree of freedom in design can be further increased.

In the above embodiment, the block 5 was formed by laying the infusion bag 10 at the temporary wall construction position X2 and then filling the laid infusion bag 10 with the mortar 9, but the embankment 2 to be formed. The block 5 may be formed in any manner as long as it can be formed so as to counteract the earth pressure of the sandbag. For example, the sandbag is formed by filling the bag with the laid portion with sand and sand to make the sandbag. The block may be formed by installing the laid portion in the embankment formation portion MS and installing it in the temporary wall surface building position X2. Also, in the above embodiment,
The waterproof main body 11 of the injection bag 10 is formed with the strip-shaped laying portion 11a. However, any material can be used as long as the injection bag 10 can engage with the embankment 2, so that it is not necessary to form a separate laying portion 11a. For example, like the injection bag 10C shown in FIG. 8, it has a waterproof main body 11C in which an injection space 13C is formed, and in the injection space 13C, a laying part can be formed which can form the laying part 11Ca in the waterproof main body 11C. By providing the space 14, when the block 5 is formed, the laying portion forming space 14 which is a part of the injection space 13C of the waterproof main body 11 of the injection bag 10 is moved from the frame 15 to a predetermined laying width D. When the waterproof main body 11C is installed so that it only protrudes, part of the waterproof main body 11C protruding from the mold 15 forms the laying portion 11Ca.
The laid portion 11Ca, which is a part of 1, may be embedded in the earth and sand 36 or the like to engage with the embankment 2. Also, the laying unit 1
1a may not be formed continuously, but may be formed intermittently like the laying portion 11Aa of another infusion bag 10A shown in FIG. 6, or may be further laid on another infusion bag 10B shown in FIG. Part 1
A string-like member such as 1Ba may be provided. Further, in order to enable the laying portions 11a, 11Aa, 11Ba to efficiently and firmly engage the earth and sand 36 of the embankment 2, the laying portions 11a, 11Aa, 11Ba are provided with protrusions, irregularities, holes and the like. Needless to say that it is good. Furthermore, although the mortar 9 is filled in the injection bag 10 in the above-mentioned embodiment, any material may be used as long as it is slow-hardening, has a predetermined strength and is fluid, for example, cement milk, soil cement or the like.
