Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a prefabricated side gutter that constitutes a waterway for drainage for various purposes such as rainwater or agricultural use, and a basin placed at an appropriate location in the side gutter. be.

(Prior art) Conventional street gutters were usually constructed by laying a large number of concrete blocks of a predetermined length with a substantially U-shaped cross section in a straight line in the soil, and connecting these concrete blocks to each other. .

There is also a construction method in which two rows of approximately flat concrete plates of a predetermined length are laid in the soil, these concrete plates are connected to each other, and concrete is poured between the two rows of concrete plates to construct the bottom wall. It was hot.

Furthermore, conventional gutter pits used as mud basins, etc., were generally manufactured on-site using cast-in-place concrete.

There was also a construction method that involved burying a pit that was entirely molded as one piece.

(Problem to be solved by the invention) When a concrete block with a predetermined length and approximately U-shaped cross section is used to construct a side gutter, the concrete block has an inner width and a depth of, for example, 400 mm.
If the standard size is 4,000 mm in length, it would weigh approximately 2,200 kg, which is very heavy, so the concrete block must be unloaded from a truck etc. on site.
Large-scale equipment such as a large crane truck was required to insert it into a predetermined position in a trench dug in the ground. Furthermore, since the concrete blocks were already integrated into the shape of the groove, loading efficiency was poor when they were transported by truck or the like.

In addition, when concrete plates of a predetermined length are used to construct gutters, it takes a lot of work to arrange the concrete plates neatly in two rows, and it also takes care to prevent the concrete plates arranged in two rows from falling over. Shoring was required to maintain the structure, which resulted in poor construction efficiency.

In addition, in the method of manufacturing a basin using cast-in-place concrete, after constructing the water channel on both sides of the basin while leaving the work area for constructing the basin, the framing of the basin is carried out, concrete is poured, and after the concrete has hardened. After removing the framework and backfilling the area around the basin, it is necessary to construct a frame between the basin and the water channel, and pour concrete to connect the two, which lengthens the construction period and requires backfilling. If this is insufficient, cracks will occur in the concrete at the joint. In addition, the appearance of the connecting portion is usually poor, and if an attempt is made to improve the appearance, it will take a longer time to construct the connecting portion.

Furthermore, in the case of a basin that is entirely molded as one piece, it is large and heavy, making it difficult to transport and construct.

An inclined surface 6b is formed over a predetermined length from the longitudinal edge of the upper surface 6a, as shown in FIG. 4, the slope gradually becoming lower as it approaches the longitudinal edge. The slope of this inclined surface 6b is, for example, about 5/65. In the joint member 1, for example, the distance between a pair of opposing side plate parts 7 and the height of the side plate parts 7 are each 400 mm,
When the length of the bottom plate portion 6 is 500 mm, the weight is approximately 200 kg.

A recessed portion 13 is formed on the outer surface of the outer side wall portion 11 except for the upper end and both ends in the length direction. For example, when the side wall member 3 has a length of 1750 mm, the weight is approximately 180 kg.

Figure 9 is an external perspective view of the box part, and the box unit 1.
5 and a pair of side wall members 3 thereon constitute a prefabricated gutter receptacle. Masu unit 15
As shown in FIGS. 10 to 12, there is a substantially flat bottom plate part 17 for a basin with a rectangular recess 16 of a wide area formed in the center of the upper surface, and both widthwise ends of the top surface of the bottom plate part 17 for a basin. A pair of substantially flat side plate portions 18 that are parallel to each other and project upward from the side portions are integrally molded from concrete. The side plates 18 for the basin are not provided protrudingly provided at both ends in the length direction of the upper surface of the bottom plate 17 for the basin, and these portions abut against the lower surface of the joint member 1 . The upper surface of the side plate part 18 for the basin is in contact with the lower surface of the side wall member 3, and the end face in the length direction of the side plate part 18 for the basin is in contact with the end face in the width direction of the end face in the length direction of the bottom plate part 6 of the joint member 1. come into contact with

When constructing a side gutter, first, a groove with a treatment width and a predetermined depth is dug at a predetermined position on the ground 2, and the joint members 1 are inserted into the groove at predetermined intervals. Then, a pair of side wall members 3 are arranged between adjacent joint members 1, respectively. At this time, both ends of the outer side wall portion 11 of the side wall member 3 are positioned in the recess 9 of the joint member 1, and the longitudinal end surface of the outer side wall portion 11 is butted against the longitudinal end surface 8a of the protruding plate portion 8. , the lower end surface of the longitudinal end of the outer side wall 11 is butted against the upper surface 6a of the bottom plate 6, and the inner surface of the longitudinal end of the outer side wall 11 is abutted against the outer surface 7a of the side plate 7. Match with. As a result, the side wall member 3 is supported by the joint member 1 in an accurately positioned state, the upper end surface of the outer side wall portion 11 is flush with the upper end surface of the protruding plate portion 8, and the outer surface of the outer side wall portion 11 is flush with the upper end surface of the protruding plate portion 8. is flush with the outer surface of the protruding plate portion 8, and the upper end surface of the inner side wall portion 12 is flush with the upper end surface of the side plate portion 7.
The inner surface of the side plate portion 7 is flush with the inner surface of the side plate portion 7. The side wall member 3 includes an outer side wall portion 11
Since the inner surfaces of both ends of are in contact with the outer surface 7a of the side plate section 7, it does not fall inward, and the outer surface of the outer side wall section 11 is supported by the side wall of the groove on the ground 2. Therefore, it will not fall outward. Therefore, shoring for supporting the side wall member 3 is not required. In the above manner, a predetermined number of joint members 1 are
After assembling the side wall members 3 and 3, concrete is cast in place to construct the bottom wall 4, and the opposing side wall members 7 are assembled.
The side gutter is completed by placing the lid 5 between the upper end surfaces and between the upper end surfaces of the inner side wall portions 12 facing each other. In this state, the top surface of the lid 5 is
and is flush with the upper end surface of the outer side wall portion 11.

In addition, when constructing the trench section, the ground 2 is excavated deeper than other parts, the trench unit 15 is placed at a predetermined height position inside the excavated hole, and the excavated area is backfilled to ensure sufficient depth. Perform compaction. Next, the joint member 1 is placed on the upper surface of both lengthwise ends of the bottom plate part 17 for the basin, and the end face in the length direction of the bottom plate part 6 of the joint member 1 is butted against the end face in the longitudinal direction of the side plate part 18 for the basin. . Then, when a pair of side wall members 3 is installed between both joint members 1 in the same manner as in the construction of the side gutter portion, the lower surface of the side wall members 3 comes into contact with the upper surface of the side plate portion 18 for the basin. In this way, the gutter unit 15 and the pair of side wall members 3 constitute a prefabricated gutter gutter. It is preferable that the cast-in-place concrete constituting the bottom wall 4 of the gutter section be constructed after the gutter section is assembled.

In this way, each of the joint member 1 and the side wall member 3 is extremely lightweight, making it easy to unload it from a truck or the like at the site or insert it into a groove in the ground 2, for example, for a small cargo with a loading weight of 2000 kg. It can be easily carried out using simple tools such as a small vehicle-mounted crane called a unit mounted on a car.
Since large-scale equipment such as large cranes is not required, construction costs can be significantly reduced. Furthermore, since the joint member 1 is very small and the side wall member 3 is substantially flat, the loading efficiency is very good when transporting by truck or the like, so that the transport cost can be reduced significantly. Moreover, simply by arranging the side wall member 3 between adjacent joint members 1, the side wall member 3 can be reliably supported by the joint member 1 in an accurately positioned state, so that the assembly work of the joint member 1 and the side wall member 3 can be easily performed. Since the construction is easy and at the same time does not require shoring of the side wall member 3, the construction can be carried out reliably in a short time, and from this also the construction cost can be significantly reduced. In particular, since the inclined surfaces 6b are formed at the four corners of the upper surface 6a of the joint member 1, the ends of the side wall members 3 are connected to the upper surface 6a of the joint member 1 at the point where the inclination angle of the gutter changes as shown in FIG. It can be supported by the ridgeline formed by the boundary with the inclined surface 6b,
Therefore, it is possible to prevent the corner portion 3a of the side wall member 3 from protruding higher than the upper surface of the joint member 1,
It is possible to avoid unevenness in the height of the side gutter. Moreover, since all four corners of the upper surface 6a of the joint member 1 are not made into sloped surfaces 6b, but leave a horizontal surface portion, no inconvenience occurs even when used on a flat portion of a side gutter.

In addition, since the basin part can be constructed using the joint member 1 of the gutter part and the side wall member 3, the special members required for the basin part are the basin bottom plate part 17 and the basin side plate part 18.
There is only a box unit 15 which is integrally molded. Therefore, compared to manufacturing the entire basin using cast-in-place concrete, this method can be constructed easily and in a short period of time, as it does not require work such as installing and removing frames or connecting the basin section to the waterway section. No cracks occur due to insufficient backfilling. Furthermore, compared to the case where the entire box is manufactured in one piece in advance, transportation and construction are easier, and the efficiency of transportation and construction can be improved.

(Another embodiment) Fig. 14 is an external perspective view of a prefabricated gutter basin in another embodiment, Fig. 15 is a plan view thereof, Fig. 16 is a front view thereof, and Fig. 17 is a side view thereof. The prefabricated gutter basin in the embodiment includes a box-shaped bottom unit 20 with an open top surface, and this bottom unit 2.
0, and a substantially frame-shaped upper unit 22 placed on the uppermost frame-shaped adjustment member 21.
The bottom unit 20, the frame-shaped adjustment member 21, and the top unit 22 are each integrally molded, and a circular recess 20a is formed in one side of the bottom unit 20. Upper unit 22
is a frame-shaped portion 24, horizontal protrusions 25 protruding from the lower ends of both longitudinal end surfaces of the frame-shaped portion 24, and two pairs of mutually parallel vertical protrusions protruding from both longitudinal end surfaces of the frame-shaped portion 24. It has a protruding part 26 and a frame-shaped part 24.
The portion sandwiched between each pair of vertical protrusions 26 is open 24a except for the lower end. The frame portion 24 is
It has a first frame portion 27 and a pair of second frame portions 28 located outside the first frame portion 27 and having a substantially U-shape and having a higher height than the first frame portion 27. are doing.
The horizontal protrusion 25 has an upper surface facing the lower surface of the longitudinal end of the side wall member 3, and the vertical protrusion 26 has a protruding end surface facing the longitudinal end surface of the inner side wall 12 of the side wall member 3. The outer surface faces the inner surface of the outer side wall portion 11 of the side wall member 3. The upper surface of the horizontal protrusion 25 includes a horizontal surface 25a and an inclined surface 25b that slopes diagonally downward from the tip of the horizontal surface 25a. That is, an inclined surface 25b is formed on the upper surface of the horizontal protrusion 25 over a predetermined length from the longitudinal edge, and gradually becomes lower as it approaches the longitudinal edge. Note that in FIGS. 16 and 17, only two frame-shaped adjustment members 21 are shown. Further, the recessed portion 20a of the bottom unit 20 has four parts excluding the bottom surface of the bottom unit 20.
The recesses 20a can be formed on any number of surfaces, and the number of recesses 20a provided on each surface is also arbitrary. Further, it is not necessary to provide the inclined surface 25b on the upper surface of the horizontal protrusion 25, and the entire horizontal surface 25b is
It may be a.

When constructing the box part, first install the bottom unit 2.
0 is installed at a predetermined height position in a hole drilled in the ground 2, and if necessary, the side wall of the bottom unit 20 is destroyed at the recess 20a, and pipes and the like are connected. Next, a predetermined number of frame-shaped adjustment members 2 are placed on the bottom unit 20.
1 is piled up, the hole dug in the ground 2 is backfilled with crushed stone, and compacted sufficiently. Next, the upper unit 22 is placed on the frame-shaped adjustment member 21 on the top floor, and the side wall members 3 are butted against both ends of the upper unit 22 in the length direction.

If you adopt the prefabricated gutter pipe of this example,
In addition to obtaining the same effects as the embodiments shown in FIGS. 9 to 12, the dimension in the width direction of the basin can be set arbitrarily at the time of manufacturing, and the depth of the basin can also be set arbitrarily depending on the number of frame-shaped adjustment members 21 installed. can. In addition, if the depth of the box may be shallow, the upper unit 22 may be placed directly on the bottom unit 20 without providing the frame-shaped adjustment member 21. Further, by breaking the side wall of the bottom unit 20 at the recess 20a and connecting a pipe or the like, the ends of the flow can be easily branched or merged.

In addition, in the prefabricated gutter of the present invention, the bottom wall 4 is constructed with cast-in-place concrete, so when installing the gutter on a steep slope with a slope of 5% or more, the bottom wall 4 can be easily shaped into a step-like shape as shown in Fig. 18. can do. In this way, the flow rate of water in the gutter can be restricted to within a certain speed, so the flow rate of water in the gutter becomes too fast and the water blows out of the gutter at the end of the downhill slope. There is no such thing.

In addition, since the bottom wall 4 is constructed with cast-in-place concrete, when laying gutters on a slope, the 19th
As shown in the figure, the bottom wall 4 can be easily made to have a slope opposite to that of the slope. Therefore, the water in the side gutter can flow in the opposite direction to the slope direction from the top to the bottom of the slope.

In addition, since the bottom wall is constructed with cast-in-place concrete, if the flow rate of water flowing in the gutter is small, it is easy to form an invert 31 by providing a recess in the center of the width direction of the bottom wall 4 as shown in Fig. 20. be able to. In this way, even when the flow rate of water in the side gutter is low, a predetermined flow rate can be ensured, and accumulation of dirt and the like can be prevented.

Furthermore, as shown in FIG. 21, by manufacturing the joint member 1 which is substantially doglegged in plan view, construction of corner cuts etc. is facilitated.

Further, as shown in FIG. 22, by forming the end portion in the length direction of the inner surface of the outer side wall portion 11 of each side wall member 3 into a tapered surface 11a, it is possible to easily accommodate curved portions. According to this embodiment, it is possible to handle curves with a radius of curvature of about 30 m, and the standard joint member 1 can be used.

Further, as shown in FIG. 23, if grooves 32 are provided on the inner surface of the side plate portion 7 along the vertical direction, and the weir plate 33 is fitted into the grooves 32 in a freely insertable and removable manner,
By inserting and removing the weir plate 33, water can be freely adjusted to flow or accumulate.

Further, as shown in FIG. 24, an opening 34 is provided in the side plate portion 7 and the protruding plate portion 8, and a groove 34a extending in the vertical direction is formed on both side walls of this opening 34.
The weir plate 35 is removably fitted to 4a, and
By providing grooves 36 along the vertical direction on the inner surface of the side plate portion 7 and fitting the weir plates 37 into these grooves 36 so as to be freely inserted and removed, water can be divided or merged by inserting and removing the weir plates 35 and 37. You can freely change the channels and water channels.

Further, as shown in FIG. 25, one of the two surfaces in the width direction of the basin portion may be made flush with the water channel portion. In other words, this embodiment basically consists of Figures 14 to 17.
Same as the embodiment shown in the figure, but one frame-shaped part 2
The outer and inner surfaces of 4 are flush with the outer and inner surfaces of side wall member 3, respectively. Of course, the bottom unit 20 and the frame-shaped adjusting member 21 are also connected to the top unit 22.
It matches the shape of.

Also, as shown in FIGS. 26 to 29, the side wall member 3
The lower end surface of the inner side wall portion 12 may be flush with the lower end surface of the bottom plate portion 6 of the joint member 1. In this way, when constructing the bottom wall 4 with cast-in-place concrete, there is no need for a formwork to prevent concrete from flowing out from between the lower sides of the side wall members 3, improving construction efficiency. can be improved. As shown in FIGS. 30 to 33, the same can be done by making the lower end surface of the outer side wall portion 11 of the side wall member 3 flush with the lower end surface of the bottom plate portion 6 of the joint member 1, excluding both ends. You can get the effect of In this embodiment, the recessed portion 13 is not provided in the outer side wall portion 11. Of course, as shown in FIGS. 34 to 37, the side wall member 3
The lower end surfaces of both the outer side wall portion 11 and the inner side wall portion 12 may be flush with the lower end surface of the bottom plate portion 6 of the joint member 1. Also in this embodiment, the outer side wall portion 1
1 is not provided with a recessed portion 13.

Further, as shown in FIG.
One of the side plate parts 7 and the protruding plate part 8 may be higher than the other. Of course, in this case, side wall members 3 are used that correspond to the heights of each side plate portion 7 and protruding plate portion 8. In this way, if the heights of the ground surfaces 39a and 39b on both sides of the gutter are different from each other,
Both earth and sand can be well supported by the joint member 1 and the side wall member 3. In this embodiment, one side plate 7 and one protruding plate 8 have the same height, and the other side plate 7 and the other protruding plate 8 have the same height. As shown in Figure 39,
By making the heights of the protruding plate parts 8 different from each other, the side plate part 7
may have the same height.

Further, as shown in FIGS. 40 and 41, grooves 41 and 42 are formed in advance across the upper end surface of the protruding plate portion 8 of the joint member 1 and the upper end surface of the outer side wall portion 11 of the side wall member 3, Both grooves 41, 4 during construction
For example, a strength member 43a such as a metal pipe material, bar material, or plate material may be inserted across the grooves 41 and 42, and the grooves 41 and 42 may be backfilled with mortar 44 or the like as necessary. In this way, the joint member 1 and the side wall member 3 can be well connected in the width direction of the gutter by the strength member 43a, so that when there is a step or the like on the ground, one side of the gutter is exposed without being buried in the ground. In such a case, it is possible to effectively prevent the occurrence of a situation in which the side wall member 3 is not supported by the earth and sand and falls outward. As shown in FIGS. 42 and 43, the groove 41 is formed over the entire length of the protruding plate part 8 of the joint member 1, and the long strength member 43b is used to connect one joint member 1 and its The side wall members 3, 3 on both sides may be connected by the same strength member 43b. Further, as shown in FIGS. 44 and 45 or 46 and 47, grooves 46, 47 are formed between the upper end surface of the side plate portion 7 of the joint member 1 and the upper end surface of the inner side wall portion 12 of the side wall member 3. are formed in advance, and both grooves 46, 4 are formed during construction.
7, insert the strength member 48a or 48b, and fill the grooves 46, 47 with mortar 49 as necessary.
A similar effect can be obtained by backfilling with a method such as the following. Moreover, these structures can also be applied to the box part.

Further, as shown in FIG. 48, grooves 51 and 52 are formed in advance along the height direction on the opposing surfaces of the protruding plate portion 8 of the joint member 1 and the outer side wall portion 11 of the side wall member 3,
During construction, a strength member 53 such as a metal plate is inserted into the space formed by both grooves 51 and 52, and the space formed by the grooves 51 and 52 is backfilled with mortar or the like as necessary. You can. Note that the grooves 51 and 52 may extend over the entire length of the protruding plate portion 8 or the outer side wall portion 11 in the height direction, or may extend up to a predetermined distance from the upper end surface. In addition, the horizontal cross-sectional shape of the grooves 51 and 52 is
In addition to a triangle, it can be any shape such as a semicircle, rectangle, or polygon. In this way, the joint member 1 and the side wall member 3
can be well connected in the width direction of the gutter by the strength member 53, so when there is a step on the ground and one side of the gutter is exposed without being buried in the ground, the side wall member 3 is not supported by earth and sand. It is possible to effectively prevent the occurrence of situations such as falling outward.
Furthermore, it is possible to easily deal with cases where the protruding plate portion 8 and the outer side wall portion 11 are not in a straight line, such as at a curved point. As shown in FIG. 49, grooves 56 and 57 are formed in advance on the opposing surfaces of the side plate part 7 of the joint member 1 and the inner side wall part 12 of the side wall member 3. Insert the strength member 58 into the space formed, and fill the groove 5 as necessary.
A similar effect can be obtained by backfilling the space formed by 6 and 57 with mortar or the like.
Moreover, these structures can also be applied to the box part.

In each of the above embodiments, an example in which the cover 5 is provided over the entire gutter including the gutter portion has been described.
The present invention is not limited to such a configuration, and the lid 5 may be provided as necessary. Note that the lid 5
If not provided, the upper end surfaces of the side grooves and the basin portions may be made flat, for example, the upper end surfaces of the side plate portion 7 and the upper end surface of the protruding plate portion 8 may be made flush.

Furthermore, in each of the above embodiments, explanations are omitted regarding joints such as mortar or rubber interposed between the opposing surfaces of each member including the box portion, for example, between the opposing surfaces of the joint member 1 and the side wall member 3. However, it goes without saying that joints should be provided where necessary.

Further, in the above embodiment, the recessed portion 13 is provided on the outer surface of the outer side wall portion 11, but this is for the purpose of reducing the weight of the side wall member 3, and the recessed portion 13 does not necessarily need to be provided.

Further, in the above embodiment, the lower end surface of the protruding plate part 8 was brought into contact with the upper surface 6a of the bottom plate part 6, but the present invention is not limited to such a configuration, and the lower end surface of the protruding plate part 8 A gap may be provided between the upper surface 6a of the bottom plate portion 6 and the upper surface 6a of the bottom plate portion 6.

Further, in the above embodiment, the longitudinal end face of the side plate portion 7 and the longitudinal end face of the bottom plate portion 6 are flush with each other, but the present invention is not limited to such a configuration; The longitudinal end surface of the portion 7 is located slightly closer to the center in the longitudinal direction than the longitudinal end surface of the bottom plate portion 6, and the lower end surface of the longitudinal end of the inner side wall portion 12 is aligned with the lower end surface of the longitudinal end of the bottom plate portion 6. It may be brought into contact with the upper surface 6a.

Further, in the above embodiment, the outer surface of the outer side wall portion 11 and the outer surface of the protruding plate portion 8 are flush with each other, but the present invention is not limited to such a configuration; The outer surface of 11 and the protruding plate part 8
A step may be provided between the outer surface and the outer surface.

Further, the material of each constituent unit of the joint member 1, the side wall member 3, or the box portion is not limited to concrete, and it goes without saying that reinforcing members such as reinforcing bars may be embedded inside these members.

(Effects of the invention) As explained above, according to the prefabricated gutter of the invention, each of the joint members and side wall members is extremely lightweight, making it easy to unload from a truck on site or carry it into a ditch on the ground. The insertion work can be easily carried out using a simple tool such as a small vehicle-mounted crane called a unit, which is mounted on a small truck with a loading weight of about 2000 kg, and can be easily inserted using a simple tool such as a small crane called a unit, which is mounted on a small truck with a loading weight of about 2000 kg. Since this is not necessary, construction costs can be significantly reduced. Further, since the joint member is very small and the side wall member is substantially flat, the loading efficiency is very good when transporting by truck, etc., so that the transport cost can be significantly reduced. Moreover,
By simply arranging the side wall members between adjacent joint members, the side wall members can be accurately positioned and reliably supported by the joint members, making it easy to assemble the joint members and the side wall members, and at the same time, the side wall members can be easily assembled. Since no shoring is required, construction can be carried out quickly and reliably, which can also significantly reduce construction costs. Furthermore, since the bottom wall is constructed from cast-in-place concrete, it is very easy to make the bottom wall step-like, make the slope of the bottom wall opposite to the road, and provide an invert on the bottom wall. Further, by slightly deforming the joint member, it is possible to easily accommodate the corner cut portion. In particular, since sloped surfaces are formed at the four corners of the upper surface of the joint member, at points where the slope angle of the gutter changes, the end of the sidewall member can be supported on the ridgeline formed by the boundary between the horizontal surface and the sloped surface. It is possible to prevent the corner portion of the side wall member from protruding higher than the upper surface of the joint member, and it is possible to avoid unevenness in the height of the side gutter. Moreover, since all four corners of the upper surface of the joint member are not made into sloped surfaces, but leave a horizontal surface portion, there is no problem at all when using the joint member on a flat portion of a side gutter.

In addition, according to the prefabricated gutter basin of the present invention, it can be constructed using the joint member of the gutter part and the side wall member, so any special members required for the basin part are integrated with the basin bottom plate part and the basin side plate part. It is only a box unit formed by molding. Therefore, compared to manufacturing the entire basin using cast-in-place concrete, this method can be constructed easily and in a short period of time, as it does not require work such as installing and removing frames or connecting the basin section to the waterway section. No cracks occur due to insufficient backfilling. Furthermore, compared to the case where the entire box is manufactured in one piece in advance, transportation and construction are easier, and the efficiency of transportation and construction can be improved.

According to another prefabricated gutter pipe of the present invention,
Since it is composed of a bottom unit, an upper unit, and one or more frame-shaped adjustment members used as necessary, it is easier to install and remove the frame than when manufacturing the entire trench using cast-in-place concrete. Since there is no need for work such as connecting the pit and waterway, construction can be done easily and in a short period of time, and there are no cracks caused by insufficient backfilling. Furthermore, compared to the case where the entire box is manufactured in one piece in advance, transportation and construction are easier, and the efficiency of transportation and construction can be improved. In particular, the dimension in the width direction of the basin can be arbitrarily set at the time of manufacture, and the depth of the basin can also be arbitrarily set by adjusting the number of frame-shaped adjustment members installed.
