The present invention has the following effects.

First, since a reinforcing member including a top reinforcing member capable of passing the paste of filler through the net is installed in the aggregate compaction layer, the paste discharged out of the top reinforcing member is integrally united with the aggregate compaction layer in an unevenly- A top pile having a diameter larger than the diameter of the top reinforcing member by about 120 mm can be formed. That is, it is possible to secure a supporting force equal to or larger than that of a top pile having a large diameter, while using a small-sized top reinforcing member.

Second, sufficient space for filling and compaction is secured between neighboring top reinforcements. Therefore, compared to the conventional top pile, it is possible to easily carry out the construction and compacting of the aggregate and secure a much more dense lower support layer.

Third, when a plurality of top reinforcing members are combined with a horizontal connecting member, a plurality of top piles can be united and structurally integrated, and a horizontal connecting member can serve as a reinforcing member.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings and preferred embodiments.

Fig. 2 is a perspective view showing an embodiment of a stator for a field-effected top pile according to the present invention.

As shown in FIG. 2, the stator stiffener of the present invention is disposed at a predetermined distance from the aggregate compaction layer 21 in order to construct a top pile placed on the aggregate compaction layer 21, A portion of the paste of the spot filling filler that is filled in the inside is outflowed to be diffused into the outer aggregate compaction layer 21 and is injected into the outer reinforcing portion 24, And a top reinforcing member 221 in which a plurality of rows of transverse members 221a and a vertical member 221b intersect each other to form a net shape.

The aggregate compaction layer 21 may be formed after a plurality of stiffeners 22 are spaced apart from each other after the ground stationary operation and then aggregates are laid on the ground 1 around the stiffener 22.

In the present invention, a stator for a top-mounted top pile is used for constructing a top pile which is laid on the aggregate compaction layer (21).

The reinforcing member 22 is formed in a cone shape having an upper portion opened to allow a filler to be installed therein and having a narrower width from the upper portion to the lower portion.

The reinforcing member 22 includes a top reinforcing member 221 through which a part of the paste of the spot filling filler to be filled therein can be discharged to the outside.

The top reinforcing member 221 is configured such that the outer aggregate is prevented from entering the inside, and the paste of the filler poured into the inside of the top supporting member 221 flows out to the outside. Accordingly, the inside of the top reinforcing member 221 and the outer thickness of the top reinforcing member 221 form a topped pile integrally. For example, in the case of using an aggregate having a size of 40 mm, when the paste flows 20 mm outside the top reinforcing member 221, the thickness of the outer reinforcing portion 24 is 60 mm, which is the sum of the paste penetration thickness and the size of the aggregate . When the conventional synthetic resin container having no net is used, the outer surface of the container and the layer of the aggregate aggregate are completely separated from each other and the gap becomes larger at the interface. In the present invention, the top reinforcing member 221 is formed as a mesh, Lt; RTI ID = 0.0 > interface. ≪ / RTI >

Therefore, the gap between the adjacent top reinforcing members 221 is sufficiently large, so that it is possible to easily carry out the construction by securing a sufficient work space in the aggregate laying and compaction process, and at the same time, the diameter of the final top pile can be sufficiently increased, It is advantageous. That is, both the workability and the structural performance can be improved.

A portion of the top reinforcing member 221 formed by the spot filling filler is a core portion 23 and a paste is formed on the outside of the top reinforcing member 221 with a certain thickness diffused into the aggregate compaction layer 21 The portion is the outer reinforcing portion 24, which can be seen in Fig. 15 (c).

The top reinforcing member 221 greatly improves the structural performance of the top pile between the inner core 23 and the outer reinforcing portion 24 on the outer side.

The top reinforcing member 221 can be manufactured using various materials such as a fiber material and a metal material.

In order to keep the shape of the top pile constant, a metal material is preferable, and a steel wire mesh or a metal mesh as shown in FIG. 2 can be used.

The paste of the spot filling filler to be filled in the reinforcing material 22 flows out to the outside through the net 222 of the top reinforcing member 221.

The size of the net 222 of the top reinforcing member 221 may be equal to or less than the size of the aggregate of the aggregate compaction layer 21 to prevent the aggregate of the aggregate compaction layer 21 from flowing into the top reinforcing member 221. Or less.

In the case of forming the top reinforcing member 221 using a steel wire netting, the top reinforcing member 221, which is a meshed member, may be formed into a conical shape having a polygonal shape in addition to a circular shape. And is advantageous in terms of transportation.

The steel pipe network having a circular flat cross-sectional shape can be manufactured by arranging a plurality of concentric circles having different diameters as a horizontal member 221a and arranging them in a plurality of rows vertically and combining them with a vertical member 221b. Or by joining the vertical member 221b to one helical horizontal member (not shown).

The total area of the net 222 of the top reinforcing member 221 may be 40% or more of the total area of the top reinforcing member 221.

In order to form the outer reinforcing portion 24 having an appropriate thickness outside the top reinforcing member 221, a net 222 having an area of at least 40% of the total area of the top reinforcing member 221 should be formed, It is advantageous that the net 222 is formed in an amount of 50% or more of the total area of the top reinforcing member 221.

When the aggregate is filled both inside and outside of the top reinforcing member 221, a separate cover member for closing the top of the top reinforcing member 221 is unnecessary, so that the installation is convenient.

3 is a perspective view showing a plurality of top reinforcing members whose center is fixed by a horizontal connecting member.

3, a plurality of the top reinforcing members 221 may be spaced apart from each other by a predetermined distance, and the plurality of top supporting members 221 may be fixed to each other by a horizontal connecting member 223.

The plurality of reinforcing members 22 can be integrally formed by connecting the plurality of top reinforcing members 221 with the horizontal connecting member 223, and moreover, a plurality of top piles can be connected to one structure.

When a reinforcing member 22 having a plurality of top reinforcing members 221 combined with the horizontal connecting member 223 is preliminarily manufactured at a factory and then installed in the field, a plurality of top piles can be easily installed at an accurate position,

In FIG. 3, the horizontal connecting member 223 is positioned at the upper center of the top reinforcing member 221, but the position of the horizontal connecting member 223 is not particularly limited.

The horizontal connecting member 223 can be pre-coupled to the top reinforcing member 221 by binding wires, welding, or the like.

The horizontal connecting member 223 may be coupled to the upper end of the top reinforcing member 221.

In this case, the horizontal connection member 223 is embedded in the filler such as concrete placed on the upper part of the pile to reinforce the reinforced concrete slab.

That is, the horizontal connecting member 223 not only improves workability by integrating a plurality of top reinforcing members 221 but also exhibits a reinforcing effect structurally.

4 is a perspective view showing a plurality of top reinforcing members fixed by a horizontal connecting member and a lateral connecting member;

4, a plurality of top reinforcing members 221 fixed by the horizontal connecting member 223 are installed on the top of the ground 1 in a plurality of rows and then are horizontally arranged in a direction perpendicular to the horizontal connecting member 223 And may be interconnected to the connector 224.

The transverse connector 224 may be coupled to the top reinforcement 221 or the horizontal connector 223 in the field by means of binding wires or the like.

The lateral link members 224 may be provided for each of the top reinforcing members 221, or may be provided separately for all the top reinforcing members 221.

The horizontal joint member 223 and the transverse joint member 224 are preferably made of reinforcing steel for reinforcing effect or the like.

Fig. 5 is a perspective view showing an embodiment of a plurality of top reinforcing members, both ends of which are fixed by horizontal connecting members, and Fig. 6 shows another embodiment of a plurality of top reinforcing members whose both ends are fixed by horizontal connecting members It is a perspective view.

As shown in FIGS. 5 and 6, the horizontal connecting members 223 may be coupled to both side edges of the upper surface of the top reinforcing member 221.

5 shows an embodiment in which the horizontal connecting member 223 is coupled to the top end of the top reinforcing member 221. [ 6 shows an embodiment in which the horizontal connecting member 223 is coupled to the vertical member at the bottom of the top end of the top reinforcing member 221. [

The conventional top pile is arranged so that the upper stiffener passes through the center of the top pile for easy transportation and handling. The reinforcement effect is limited because the upper stiffener passes through the thickest section of the top pile.

Therefore, in the present invention, the horizontal connecting member 223 is arranged at the outer edge of the top reinforcing member 221, which is a thin portion of the top pile, so that the horizontal connecting member 223 can exhibit a reinforcing effect structurally.

It is preferable that the horizontal connecting member 223 passes between a center line of the horizontal connecting member 223 and a point D / 6 away from the outer side of the top reinforcing member 221 and the outer side thereof.

First, the center of the top pile is the thickest, so no additional reinforcement is needed, and if the horizontal connecting member 223 passes over the outer side of the thinner top reinforcing member 221, the reinforcing effect on the topping pile is large .

Secondly, if the horizontally connecting member 223 is disposed so as to pass the center of the top reinforcing member 221, the produced reinforcing member 22 can not be stacked, but if the horizontally connecting member 223 is disposed so as to pass the outside of the top reinforcing member 221, It can be stacked, so it is very easy to carry and handle.

Third, a cover member 225 may be provided to prevent the aggregate from entering the inside of the top reinforcing member 221 in the step of installing and compacting the aggregate after the installation of the reinforcing member 22. [ However, when the horizontal coupling member 223 is positioned at the center of the top reinforcing member 221, it is difficult to install the cover member 225 due to the interference of the horizontal coupling member 223, This is because the cover member 225 can be easily installed between the pair of horizontal connection members 223 by arranging them on both sides.

The plurality of topsuger members 221 may be configured such that the diameter of the top surface is 50 to 90% of the center interval between neighboring topsensers 221.

Conventional top piles are constructed such that a plurality of neighboring top piles are brought into contact with each other. In contrast, in the present invention, since the outer reinforcing portion 24 is naturally enlarged and connected when the core portion 23 is formed in the reinforcing material 22, it is not necessary to provide the adjacent reinforcing materials 22 in contact with each other.

Therefore, since the neighboring stiffeners 22 can be spaced apart from each other, the interval between the top piles is large, which makes it easy to construct and compact the aggregate and secure a dense lower support layer.

If the diameter of the upper surface of the stiffener 22 is less than 50% of the center distance between the stiffeners 22, the volume of the top pile is too small and the contact area with the aggregate compaction layer 21 is small, .

If the diameter of the upper surface of the stiffener 22 exceeds 90% of the center spacing between the stiffeners 22, the interval between the stiffeners 22 is too narrow, which makes it difficult to install and fill the aggregate.

Considering these points, it can be said that the diameter of the upper surface of the stiffener 22 is preferably 60% to 80% of the center spacing between the stiffeners 22.

Fig. 7 is a side view showing another embodiment of the stator for a field-effected top pile of the present invention.

As shown in FIG. 7, the upper portion of the top reinforcing member 221 may be curved outward to be arcuate.

If the top end of the top reinforcing member 221 is curved outwardly, the outer reinforcing portion 24 between the adjacent top reinforcing members 221 can more reliably form the arch structure, thereby increasing the structural performance.

FIG. 8 is a perspective view of a stator for a pile according to an embodiment of the present invention having a cover member according to an embodiment of the present invention, FIG. 9 is a perspective view of a stator for a pile according to another embodiment of the present invention, 10 is an exploded perspective view showing the engagement relationship of the cover member in Fig. And Fig. 11 is a perspective view showing a coupling relationship between the cover member and the top reinforcing member according to still another embodiment.

As shown in FIGS. 8 and 9, a cover member 225 for closing the opened top surface may be detachably coupled to the top of the top reinforcing member 221.

The cover member 225 closes the top of the top reinforcing member 221. Accordingly, it is possible to prevent the aggregate from entering the inside of the top reinforcing member 221 when the aggregate is installed between adjacent reinforcing members 22 after the stiffener 22 is installed on the ground 1.

The cover member 225 is removable after the aggregate is installed and compacted.

The cover member 225 may be configured to be fitted on each of the top reinforcing members 221 as shown in FIG.

9 and 10, the cover member 225 may be configured to cover the upper surface of the top reinforcing member 221. [ At this time, the cover member 225 may be configured such that the latching plate 226 is protruded from both ends of the cover member 225 to cover the upper surface of the top reinforcing member 221.

The cover member 225 may be inserted between the pair of horizontal connection members 223 when the pair of horizontal connection members 223 are coupled to the edge of the top support member 221. [ In this case, a certain space may be formed between the horizontal connecting member 223 and the outer end of the top reinforcing member 221. Since this space is relatively narrow, the aggregate does not penetrate even if it is not closed by the cover member 225 separately.

On the other hand, when the horizontal connecting member 223 and the horizontal connecting member 224 are arranged in a cross shape so as to cross the center of the top reinforcing member 221 as shown in FIG. 11, An insertion groove 227 through which the coupling member 223 and the transverse coupling member 224 pass can be formed.

The position of the insertion groove 227 can be formed in consideration of the position of the horizontal coupling member 223 and / or the lateral coupling member 224. [

12 is a perspective view showing a stiffener provided with a sub-net.

As shown in FIG. 12, an auxiliary net 228 may be provided in the top reinforcing member 221.

When the size of the net 222 of the top reinforcing member 221 is larger than the aggregate size of the aggregate compaction layer 21, the size of the net 222 of the top reinforcing member 221 is smaller than the aggregate size of the aggregate compaction layer 21 The auxiliary net 228 can be inserted into the top reinforcing member 221.

The auxiliary net 228 does not need to be thick because the aggregate must be inflowed only, and a variety of net- works such as a metal net and a fiber net can be used.

The auxiliary net 228 may be coupled with the top reinforcing member 221 to prevent the auxiliary net 228 from being lifted when the filling material is charged and a separate filling material may be filled in the auxiliary net 228.

13 is a cross-sectional view showing the integrated top pile foundation of the present invention.

The present invention relates to an integral type top pile foundation using a stiffener for a top-mounted top pile, which is formed by using a stiffener for a site-topped top pile according to the present invention described above with reference to Figs. 2 to 12.

As shown in FIG. 13, the integral type top pile foundation of the present invention comprises a aggregate compaction layer 21 installed on the ground 1; (22) provided in the aggregate compaction layer (21) so that an upper surface thereof is exposed above the aggregate compaction layer (21); A core portion 23 formed by placing a filler material in the inside of the top reinforcing body 221 of the stator pile for stator 22; An outer reinforcing portion 24 formed by mixing the paste of the filler discharged from the top reinforcing body 221 with the aggregate compaction layer 21 outside the top reinforcing body 221 and curing the same; And an upper connecting layer 26 integrally formed with the core portion 23 and the outer reinforcing portion 24 by pouring a filling material into the upper portion of the core portion 23 and the aggregate compaction layer 21. .

The aggregate compaction layer 21 may be formed by arranging an aggregate on the ground 1 around the reinforcing material 22 after the stiffener 22 is installed after the ground stopping operation.

The stator top pile stiffener 22 is provided in the aggregate compaction layer 21 so that an upper surface thereof is exposed above the aggregate pileup layer 21. [

The upper reinforcing member 22 is a cone shaped upper cone lowering cone having an open upper part and a top reinforcing member 227 formed in a net shape in which a plurality of net eyes 222 are formed so that a part of the paste of the spot filling filler, 221).

The core portion 23 is formed by placing a filler material inside the top reinforcing body 221 of the stator pile for stator 22 and hardening it.

The core 23 is filled in the filler through the open top of the stiffener 22 and is formed in situ.

The core portion 23 may be formed by directly filling the filler material in the reinforcement material 22 or by injecting cement mortar or sticky grout having appropriate slump into the reinforcement material 22 before filling the aggregate material .

The filler is a curable material such as concrete or grout material.

Here, the filling material may be filled only in the interior of each of the reinforcing members 22, or may be integrally filled with a predetermined height to the upper portion of the reinforcing member 22 and the upper portion of the aggregate compaction layer 21.

The outer reinforcing portion 24 is formed by mixing the paste of the filler flowing out from the top reinforcing body 221 with the aggregate compaction layer 21 outside the top reinforcing body 221 and curing.

The outer reinforcing portion 24 is formed on the outer side of the reinforcing member 22. For example, the cement paste, fine aggregate, and the like in the concrete placed in the reinforcing member 22 are discharged to the outside through the net 222, The outer reinforcing portion 24 can be formed while being diffused into the layer 21.

Accordingly, the reinforcing member 22 acts as a reinforcing bar of the reinforced concrete structure between the inner core 23 and the outer reinforcing portion 24, thereby greatly improving the structural performance of the put-up reinforcing steel pile.

The outer reinforcing portion 24 may be formed by adjusting the slump of the filler or adjusting the diffusion range of the filler injected into the aggregate compaction layer 21 using an admixture.

The upper connection layer 26 is integrally formed with the core portion 23 and the outer reinforcement portion 24 by pouring the filler material on the core portion 23 and the aggregate compaction layer 21.

The upper connection layer 26 may be abandoned concrete or foundation.

At this time, the upper connection layer 26 may be integrally formed by being poured at the same time with the filling material poured into the core portion 23 and the outer reinforcing portion 24.

Accordingly, the top pile and the upper connecting layer 26 can be integrated.

In addition, a wire mesh may be provided on the upper portion of the aggregate compaction layer (21) and the stator pile stiffener (22).

The wire mesh (not shown) is positioned above the aggregate compaction layer 21 and the reinforcing member 22 to reinforce the upper connection layer 26.

As described above, the integrated top pile foundation of the present invention can form the top pile directly on the aggregate compaction layer 21 by charging the filling material such as the spotted concrete in the state where the reinforcing material 22 is installed, . In addition, it is convenient and economical because there is no need to manufacture or transport the top pile or top container separately.

The core portion 23 of the top pile is made of a high quality filler material reinforced by the reinforcing material 22, and the aggregate of the top layer pile supporting pillars 21, (23) The filler injected at the time of filling the filler material forms the outer reinforcement portion (24), so that the structure performance is excellent and the construction speed is also very fast.

In addition, the upper portion of the aggregate compaction layer 21 has a relatively small density of aggregate. The area of the outer reinforcing portion 24 on the upper side of the reinforcing member 22 is enlarged so that the outer reinforcing portion 24 between the neighboring reinforcing members 22 may have an arch shape. In this case, the structural performance of the top pile can be greatly improved by the arch behavior of the outer reinforcing portion 24. [

FIG. 14 is a cross-sectional view showing the integrated top pile foundation of the present invention having a tail portion.

As shown in FIG. 14, the integral top type pile foundation of the present invention may be further provided with a tee part 27 which is inserted into the ground 1 and a part of which is projected upward to be located inside the top reinforcing body 221 have.

The frame part 27 can be installed separately from the reinforcing material 22. When the frame part 27 is provided inside the reinforcing material 22, it is easy to secure the position of the reinforcing material 22 constantly. Further, it is possible to further secure the support force, and it is possible to reduce deformation of the top pile when the load acts on the structure.

Since the tread portion 27 is inserted into the ground 1 where the stopping operation is completed, it is possible to expect an additional supporting force to be secured.

The frame portion 27 can be made of a material having high rigidity such as a steel pipe or a concrete material.

The ground 1 may be a soil sand in the field or may be a first aggregate compaction layer 21 when the ground is weak.

That is, after the aggregate material compaction layer 21 is formed in a primary shape, the frame portion 27 is inserted into the aggregate material compaction layer 21, and then the stiffener 22 The aggregate compaction layer 21 may be formed secondarily.

FIG. 15 is a view showing a method of constructing an integral type top pile base according to an embodiment of the present invention.

A method of constructing an integrated top pile base according to the present invention is for constructing an integrated top pile foundation using the above-mentioned stator for a top-mounted top pile pile, wherein (a) a plurality of reinforcing materials (22) are installed on the top of the ground ; (b) laying an aggregate on the ground 1 around the top reinforcing member 221 and compaction to form an aggregate compaction layer 21; (C) filling the filler into the inner space and the upper space of the top reinforcing member 221 to form a core portion 23, an outer reinforcing portion 24, and an upper connecting layer 26; And a control unit.

In the step (a), the stiffener 22 is installed after the stopping operation of the ground 1 (Fig. 15 (a)).

A horizontal connection member 223 may be provided on the upper portion of the reinforcing member 22 to interconnect the plurality of stiffeners 22 and a horizontal connection member 224 may be provided perpendicularly to the horizontal connection member 223.

In order to prevent deformation of the reinforcing member 22 when the aggregate compaction layer 21 is formed in step (b), the inner shape of the top reinforcing member 221 is formed in the top reinforcing member 221 in step (a) It is possible to insert the shape retaining mouth 28 having the same shape as the shape retaining mouth 28.

The shape retaining mouth 28 is provided to prevent the shape of the reinforcement 22 from being deformed when the aggregate is formed and collapsed to form the aggregate compaction layer 21 around the reinforcement 22. [

The shape retaining mouth 28 is inserted into the top reinforcing body 221 to support the reinforcing material 22. [

The shape retaining mouth 28 may be made of wood, steel, sand bag or the like which can be used repeatedly.

In the step (b), an aggregate is laid on the ground 1 around the top reinforcing member 221, and then the aggregate compaction layer 21 is formed (FIG. 15 (b)).

At this time, the aggregate is laid in a space between adjacent reinforcing materials (22) and then chopped.

The compaction of the aggregate is preferably carried out using a compactor or a vibrator.

In particular, since sufficient space can be secured between the reinforcing members 22 when the aggregate is collapsed by the vibrator, it is advantageous to lay and compact the aggregate. In addition, since the vibrator can be operated easily, it is advantageous to secure the compaction of the aggregate compaction layer 21 as compared with the conventional top pile.

In the step (a), when the shape-retaining mouth 28 having the same shape as the inside shape of the top-reinforcing body 221 is inserted into the inside of the top-reinforcing body 221, the shape retaining mouth 28 ) May be removed after the aggregate is compacted in the step (b).

The shape holder 28 may be retained for structural reinforcement of the core portion 23 as the case may be.

In step (c), the filler is filled in the inner space of the top reinforcing body 221 to form the core 23 and the outer reinforcing part 24 (FIG. 15 (c)).

In the step (c), the filling material is concrete, and the upper connecting layer 26 may be formed on the aggregate compaction layer 21, the stiffener 22, and the core portion 23. At this time, the upper connection layer 26 may be poured simultaneously with the concrete for forming the core portion 23 and the outer reinforcing portion 24. [

Simultaneously or immediately after the concrete for forming the core portion 23 and the outer reinforcement portion 24 is laid, concrete for forming the upper connection layer 26 is directly placed on the upper portion of the top pile and the upper connection layer 26 Can be integrated.

The upper connection layer 26 may be integrally formed with the upper structure by protruding a shear connection member on the upper portion of the upper connection layer 26.

FIG. 16 is a view showing a method of constructing an integrated top pile base according to another embodiment of the present invention.

The method for constructing the integrated top pile foundation of the present invention is for constructing the foundation of a piling foundation of the present invention, comprising the steps of: (a) installing a plurality of reinforcing materials (22) on a ground (1) (b) An aggregate is installed on the inner space of the top-reinforcing body 221 and the ground 1 around the top reinforcing body 221, and the aggregate around the top-reinforcing body 221 is ground to form the aggregate- ; And (c) filling the filling material into the top of the top reinforcing member 221 filled with the aggregate to form the core portion 23 and the outer reinforcing portion 24; And a control unit.

In this case, in the step (b), instead of the shape holding tool 28, the top reinforcing member 221 is filled with the compaction aggregate to prevent the deformation of the reinforcing member 22. [

The compaction aggregate inserted into the top reinforcing body 221 may be used as a material of the deep portion 23 without being removed and the filler such as cement grout or mortar to be injected into the top reinforcing body 221, 23 and an outer reinforcing portion 24 are formed.

The rest of the configuration and the role of each constitution are the same as in the method of constructing the integrated top pile foundation of the present invention described above with reference to FIG.

Specifically, a method of constructing the integrated top pile foundation of the present invention shown in FIG. 16 will be described.

16 (a) shows the step (a). In the step (a), the shape retaining mouth 28 is inserted into the top reinforcing body 221.

FIG. 16 (b) shows the step (b), in which the aggregate compaction layer 21 is formed.

Thereafter, as shown in Fig. 16 (c), a step of removing the shape retaining mouth 28 inside the topmost reinforcing body 221 is carried out.

(C) filling the inner space of the stiffener 22 with the filler to form the core 23 and the outer reinforcement 24 (FIG. 16 (d)).

Finally, an upper connection layer 26 can be formed on the aggregate compaction layer 21, the stiffener 22, and the core 23 (FIG. 16 (e)). In this case, The reinforcing member 22 can be installed at the same time as the filler is filled in the space.

The filling material filling the inside of the top reinforcing body 221 in which the aggregate is installed should be filled tightly in the space between the aggregates inside the top reinforcing body 221. Therefore, it is preferable that the filling material is high in fluidity such as grout or mortar, It is preferable that the area of the net 222 is formed to be slightly lower than the entire surface area of the top reinforcing member 221 in order to prevent excessive leakage of the net 222 through the net 222. Further, the filling material placed on the upper part of the top reinforcing body 221 requires a large strength, so that it is preferable that the fluidity is somewhat low like concrete.
