Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of stacking foamable synthetic resin blocks for embankment and a structure for stacking the blocks.

[0002]

In recent years, a civil engineering method utilizing the lightweight, self-supporting and compression-resistant properties of Styrofoam has been developed, and has been developed for roads, railways, runways, development sites, residential lands, landfills, and the like.
Embankment when constructing a park, etc. It is widely considered for use as embankment, which is the foundation of buildings.

[0003] For example, Japanese Patent Application Laid-Open No. 1-66316 discloses a lightweight embankment composed of a block structure layer in which a number of lightweight blocks are stacked, and a covering layer made of a polyurethane foam forming the outside of the block structure layer. A building method, a step of stacking the lightweight blocks and assembling a target block structure layer on the ground, and a step of assembling a formwork along the design slope of the embankment outside the assembled block structure layer. Injecting a raw material for polyurethane foam before foaming and curing into the mold so as to cover the entire block structure layer; and removing the mold after foaming and curing the polyurethane foam raw material. (JP-A-1-66316, page 1, left column, line 14 to right column, line 7) has been proposed.

[0004] In the case of forming a block structure layer by stacking such lightweight blocks, the blocks are light in weight and easy to be processed on site, so that compared with the case where conventional sand, earth and sand, etc. are used, the on-site structure is reduced. In addition to improving the workability of the embankment, consolidation settlement at the lower part of the embankment can be prevented.

[0005] The use of such a lightweight block makes it possible to carry out the work manually, but in actual construction, the blocks are stacked one by one at the site and assembled while aligning the blocks. It takes time to work. For example, at the embankment one step higher than the ground surface,
Stack the blocks further on the arranged block layer,
Since the upper surface of the block structure layer gradually becomes higher and work is performed in a limited range on the block layer, blocks cannot be temporarily placed on the block layer, and the blocks are aligned while being transferred one by one. Since they are assembled, the work time cannot be speeded up.
In addition, in the case of a groove-shaped embankment that is one step lower than the ground surface due to backfilling, etc., work space is restricted at the bottom side of the embankment point, and multiple blocks can not be temporarily placed on the bottom side, Since the blocks are aligned and assembled while lowering the blocks one by one from the ground surface, it is not possible to speed up the working time.

Further, after stacking blocks, in order to fix those blocks, the above-mentioned Japanese Patent Application Laid-Open No. 1-66316 is used.
In the publication, a mold is assembled around the block structure layer, and a raw material for polyurethane foam is injected into the mold. Therefore, a mold framework covering the entire block structure layer and a raw material for foam are injected. Work is required. Therefore, a fixing structure is used in which concrete is poured or a fixing net is provided on the stacked blocks, but such a fixing structure becomes unstable with respect to a lateral force, In this type of embankment, there is a possibility that the block may cause side slip due to a horizontal load such as an earthquake or a load on the embankment. On the other hand, in Japanese Unexamined Patent Publication No. Hei 3-81405, a buckle (see FIG. 2) as a dowel is arranged on the overlapping surface of the blocks.
The lower claws are inserted into the upper and lower blocks, respectively, to prevent the blocks from shifting in the horizontal direction. However, in such a fixing method using a tie, after the lower claw is inserted into the upper surface of the lower block to fix the tie, the upper claw of the tie is perpendicular to the lower surface of the upper block. Since it is necessary to insert and set, the upper block must be lowered almost vertically with respect to the lower block, and the positioning work becomes complicated. That is, it is difficult to move the upper block in the lateral direction and align it after inserting the upper claw portion into the lower surface of the upper block. In addition, in the case of a plurality of stacked blocks, a tie must be provided between the upper and lower blocks, and since they are connected only at the tie, only the tie is applied when a lateral force is applied. The upper and lower blocks may not be pressed against each other only by using the fasteners, so that the fixing in the vertical direction is required.

Therefore, an object of the present invention is to provide a method for stacking foamable synthetic resin blocks of an embankment, which can shorten the construction time and is excellent in workability. It is an object of the present invention to provide a structure for stacking foamable synthetic resin blocks of an embankment capable of suppressing lateral displacement of the blocks.

[0008]

According to a first aspect of the present invention, in the stacking method for stacking foamable synthetic resin blocks, a block unit is formed by stacking the blocks in a plurality of stages. It is a method of installing at the embankment part, because it is possible to form a block unit by stacking multiple blocks at a place suitable for work,
Block assembly work is easy, and the block unit is transported to the embankment as it is and installed, so it can be installed immediately after transportation to the embankment, eliminating the need to temporarily place blocks and restricting the work space. The work of assembling blocks at the receiving embankment site is reduced.

According to a second aspect of the present invention, in the stacking method, a connecting member is inserted in a thickness direction of the block unit, and the blocks of the block unit are integrated by fastening stoppers provided at both ends of the connecting member. This is a method, in which a plurality of blocks are tightened and integrated by the connecting member and the fastening stopper, so that the lateral displacement of the blocks can be suppressed by frictional resistance between the surfaces of the blocks.

Further, in the stacking structure according to a third aspect of the present invention, in the stacking structure formed by stacking foamable synthetic resin blocks, a block unit in which the blocks are stacked in a plurality of stages is formed, and a connecting member is provided in a thickness direction of the block unit. And the block of the block unit is integrated with the fastening stoppers provided at both ends of the connecting member. The connecting member and the fastening stopper are used to tighten and integrate a plurality of blocks. Therefore, the lateral displacement of the blocks can be suppressed by the frictional resistance between the surfaces of the blocks.

[0011]

Embodiments of the present invention will be described below with reference to the accompanying drawings. 1 to 11 show a first embodiment of the present invention, in which FIG. 1 shows a road, railway, runway,
It shows an embankment 1 such as a development site, a residential site, a landfill, a park, and the like.

A backfill structure using a foamable synthetic resin block 11 is provided in the embankment 1. Examples of the foamable synthetic resin include polystyrene foam, polyethylene foam, polypropylene foam, and urethane foam. As shown in FIG. 3, the block 11 has a rectangular flat plate shape, a length L is about twice the width W, and a thickness is about half the width W.
At the center in the width direction, two holes 12, 12 are formed side by side in the length direction.
It is formed at about one-half the position. That is, the hole 12 is located at a position about half the width W, and the hole 12 is formed substantially perpendicular to the upper and lower surfaces of the block 11. Then, for example, the block 11 has a length L of 2 m (meters),
One having a width W of 1 m and a thickness of 0.5 m is used. The hole 12 is formed in a tapered shape that expands from the lower surface of the block 11 toward the upper surface. Therefore, block 11
In the molding of, a nest (not shown) for forming a hole 12 is provided in a mold (not shown) forming the upper surface side of the block, and the hole 12 is formed by moving the mold upward. can do. Alternatively, the hole 12 may be formed after the block 11 is formed.

Further, according to the present invention, in a factory or on-site, two blocks 11, 11 are arranged on the left and right, and two blocks 11, 11 are arranged on these blocks 11, 11 in front and rear, and are superimposed. On top of that, the two blocks arranged on the left and right are arranged side by side and superimposed. In this way, the upper and lower blocks 11, 11 are superposed on a plurality of stages by changing the plane orientation of the upper and lower stages by 90 degrees. Indicates a block unit 13 in which blocks 11 are stacked in six stages. In this case, the hole 12 has a length L from the end at one half of the width W of the block 11.
, The holes 12 of the upper and lower blocks 11 which are different in front, rear, left and right are vertically continuous. Then, the connecting member 14 is inserted into the continuous holes 12, 12,... Of the block unit 13. The connecting member 14 in this example is a round bar made of steel or the like, and female screw portions 15 are formed at both ends of the connecting member 14. At both ends of the connecting member 14, fastening stoppers 16 are provided. The stopper 16 is, as shown in FIG.
Nut screwed into the larger pressure receiving plate 17 and the female screw portion 15
And the connecting member at the center of the pressure receiving plate 17.
A hole 17A is formed through the end of the hole 14 and the hole 17A is formed.
Around the 17A, there is formed a recess 17B recessed toward the block 11, and the nut 18 is formed so as to be housed in the recess 17B. By changing the depth of the recess 17B, the end of the connecting member 14 can be stored. Then, after inserting the connecting member 14 into the hole 12, the pressure receiving plates 17 are arranged vertically,
A plurality of blocks 11 are integrated by tightening a nut 18 with a predetermined force. In this case, the upper and lower surfaces of the block unit 13
If the nut 18 is tightened so that the outer surface of the pressure receiving plate 17 is substantially flush with the outer surface, there is no portion protruding from the upper and lower surfaces of the block 11, which is preferable for stacking and laying. FIG. 6 is a cross-sectional view of the lower portion of the block unit 13. The end of the connecting member 14 is cut off as necessary, and the nut 18 is housed in the recess 17B.

Next, the tension required for the connecting member 14 will be described with reference to FIG. In this description, the block
The description is based on the assumption that the unit weight of 11 is 16 kg / m ³ . In FIG. 7, it is assumed that the block unit 13 is arranged in the lateral direction, and that one side face is a fulcrum S of the moment and the maximum shear force applied to the overlapping surface K of the left block 11 on the assumption that the left block 11 is restrained. Find τmax. The weight Wt of the block 11 on the right side excluding the block 11 on the left side is vertical (2 m) × width (2 m) × height (2.5 m) × unit weight (16 kg /
m ³ ) to 0.16 tf. When a weight of Wt = 0.16 tf acts on the center of the block unit 13 in the direction, the moment M is given by the following equation.

M = Wt × H / 2 (where H is the height of the block unit 13) Therefore, M = 0.16 ×
3/2 = 0.24 tf · m. Since the length h from the fulcrum S to the overlapping surface K is 0.5 m, the shear force τmax applied to the overlapping surface K is determined from the moment balance.
Becomes the following equation.

Τmax = M / h = 0.24 / 0.5 = 0.48 tf The pressure required to oppose the maximum shearing force τmax by the frictional force of the block 11 is applied to the connecting member 14.
To give.

Μ: The coefficient of friction of the block 11 is 0.6 (reference value of styrene foam blocks), a: the contact area of the block is 1 m ² , and Fs: the safety factor is 1.2. Also,
Pmax is the compressive load at the maximum shearing force τmax.

Pmax = (τmax × Fs) / (μ × a) Therefore, Pmax becomes 0.48 tf / m ² , and the movement of the block 11 can be prevented by pushing from above and below 480 kg per m ² . As described above, in the present invention, the plurality of blocks 11 are tightened by the connecting members 14 and the lateral displacement of the blocks 11 is prevented by the frictional resistance between the surfaces of the blocks 11. When a steel rod or wire is used for the connecting member 14, its diameter may be about 3 to 10 mm. After screwing the nuts 18 and 25, the connecting member 14
Unnecessary ends may be cut, and a round bar having a diameter of about 3 to 10 mm can be cut relatively easily even on site.

Next, a construction method using the block unit 13 will be described.
A plurality of blocks 11 are integrated to form the block unit 13
To form Further, a connecting member 14 longer than the height of the block unit 13 is used, and the female screw portion 15 of the connecting member 14 is projected from the upper and lower surfaces of the block unit 13. A cap nut 19 is screwed onto the protruding female screw portion 15, and the cap nut 19 is provided with a suspending portion 19A at an upper portion.
A ring-shaped thing, a hook-shaped thing, etc. are used as 19A. The cap nut 19 is fixed in this manner, and
Using 19A, lift the block unit 13 and fill the embankment 1
Lay it directly at the installation location. FIG. 4 shows a dedicated lifting frame 20, which is substantially H-shaped in plan view and whose end is located above the block unit 13.
At the lower part of the lifting frame 20, hooks 20A are provided corresponding to the holes 12 to be locked to the hanging portions 19A. Further, on the upper surface of the lifting frame 20, the sub-wires 21 are respectively connected to the four positions on the end side and the center of the center of gravity, and these five sub-wires 21 are connected to the wire main body 22 at the upper center. The main body 22 is moved up and down by a heavy machine (not shown) such as a crane. Accordingly, since each connecting member 14 is lifted almost directly upward through the hard hanging frame 20, the block unit is not compressed at the abutting surfaces of the adjacent blocks 11 during lifting, and the block unit is kept in a shape-retaining state. 13 can be lifted. Then, the lifted block unit 13 is hung as it is at the installation location of the embankment 1 and installed, and the block unit 13 is installed according to the shape of the embankment 1. In this case, the block unit 13 is 4
Since the side surface is a flat rectangular parallelepiped, the alignment is easy. FIG. 8 illustrates the on-site processing of the block unit 13. In order to cut the surface of the block unit 13 obliquely according to the shape of the site, a ruler 31 is applied to the block unit 13 to heat a nichrome wire or the like. By moving the line 32 along the ruler 31, a desired shape is cut. Reference numeral 33 denotes a heating means for the heating wire 32. Also heating wire
It can be cut with a saw or the like without using 32. In this case, since the connecting member 14 is inserted through the center of the block unit 13, the cutting work such as diagonal cutting of the four side surfaces can be easily performed without obstructing the cutting operation.

The adjacent block units 13 are connected by a connecting member 23. As the connecting member 23, a plate piece having locking portions 24 at both ends is used, and in FIG. 9A, notched locking portions 24, 24 are provided on both sides in the width direction. FIG. 9 (B) shows an example in which elongated holes 24A, 24A are provided on both sides in the length direction.
(C) shows the case where the locking portions 24, 24A are provided on both sides. Then, the cap nut 19 is removed from the block unit 13 where the installation is completed, the locking portion 24 is locked to the female screw portion 15 of the adjacent block unit 13, and a nut 25 for a connecting tool is screwed on. 23 connects adjacent block units 13. Further, as shown in FIGS. 10 and 11, the block units 13 adjacent to each other in the left-right direction and the front-back direction are connected by the connecting tool 23. Further, as shown in FIG. 11, the block units 13, 13 whose corners are adjacent to each other can be connected by the connecting tool 23A. When connecting a plurality of connecting tools 23, 23A to one female screw portion 15,
The connecting members 23, 23A are overlapped on the locking portion 24 side and a nut is
You only have to screw 25. The connecting member 23A has the same configuration as that of the connecting member 23 except that the length is different. Also nut
After screwing 25, the excess portion of the female screw portion 15 is cut by a cutter (not shown) or the like. After this cutting, a concrete layer 26 is formed by cast-in-place concrete on the upper surface of the lower block layer A formed by arranging the block units 13 for height adjustment. Since the upper surface of the concrete layer 26 formed by the cast-in-place concrete is substantially horizontal, the block units 13 are arranged on the concrete layer 26 to form the upper block layer B. On the upper surface side of the block unit 13, the block unit 13
Connect with each other. After the backfill structure of the embankment 1 is formed by the block 11 in this manner, the slope 27,
27, and a pavement surface 28 is formed on the upper part as necessary. In the connection tools 23, 23A, and 23B, when the notches 24 are notched in the width direction, the female screw 15
In the one having the long hole-shaped locking portion 24A in the longitudinal direction, the dimensional error between the female screw portions 15, 15 can be absorbed.
