BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for civil engineering construction and a frame for civil engineering construction.

[0002]

2. Description of the Related Art Construction methods for resisting earth pressure and preventing the collapse of soil and sand include methods for striking concrete, methods for using concrete secondary product blocks, methods for forming walls by masonry, and combinations of these methods. The construction method is used. Further, as a method of preventing collapse of sloped hillsides and protection of dilapidation, a method of combining vegetation and slag with other walls has been used. By the way, due to the shortage of forest workers and the aging of recent years, due to the lack of civil engineering materials that are collected and produced from mountain forests such as rough trees, shrubs, saplings and logs, construction methods using natural and soft materials have been shunned. The number of hard wall construction methods using secondary products is increasing. In such a hard wall construction method, the functionality, economy, and ease of construction are emphasized, but the moistness such as scenic ease and familiarity is lost.

On the other hand, in small and medium-sized rivers in small cities and rural areas, the embankments are masonry, concrete retaining walls,
It is hardened by the three-sided construction method using concrete secondary product blocks. In addition, in small-scale waterways for agricultural use or water supply and drainage related to life, it is common to construct fence boards made of concrete plates or U-shaped concrete blocks. Although this construction method is rich in ease of construction, economical efficiency or functionality, it also causes flood disasters and has a tendency to neglect the natural environment,
The scenery is not so kind.

In recent years, environmental protection and harmony are being emphasized also in the civil engineering method, and in the river construction method, the multi-natural construction method is being reviewed with the aim of becoming closer to nature. In view of these circumstances, we have developed and disseminated earth retaining walls, revetments for small and medium-sized rivers and waterways using materials that are more natural, and that are friendly to both humans and animals and plants. It is desirable to create an environment of a hometown and a stream where insects and small fish live, as well as green and flowers. In response to this request, conventionally, for example, a plurality of timber piles are driven into the ground to form a fence-shaped earth retaining wall body or a river revetment. At this time, in order to prevent the outflow of earth and sand, it is necessary to bring adjacent piles of timber into contact with each other or to arrange them closely so that the distance between them is not more than a predetermined interval.

[0005]

However, in the method of driving the piles of wood into the ground, it is a work of driving the piles of wood one by one, and if a fence-shaped earth retaining wall body is formed by this, the work efficiency is increased. Was very bad. In addition, depending on the construction site, there were places where piles could not be driven, making it difficult to effectively use wood for soil retention. Therefore, an object of the present invention is to provide a civil engineering construction method and a civil engineering construction frame body for easily constructing an earth retaining wall body or a river revetment, etc. by using wood that can achieve harmony with environmental protection. To do.

[0006]

In order to achieve the above object, the present invention has the following constitution. That is, the present invention is
A unit fence-shaped member is formed by aligning a plurality of timbers in a fence shape, and the unit fence-shaped members are arranged so as to face each other so that the facing unit fence-shaped members are erected at predetermined intervals. A civil engineering construction method is characterized in that a frame body is formed by connecting with a space holding member, and a filling material such as earth and sand is filled inside the frame body to construct an earth retaining material.

Further, according to the present invention, unit fence-shaped members formed by aligning a plurality of timbers in a fence shape are arranged so as to face each other, and the facing unit fence-shaped members are erected at predetermined intervals. It is formed in a frame shape by connecting with a space holding member so that the unit rail members facing each other can be folded in a direction in which they approach each other. There is also a frame for civil engineering construction, which is characterized by being connected.

[0008]

According to the civil engineering method of the present invention, the unit fence-shaped members facing each other are connected by the spacing member to form a frame, and the filling is filled in the frame. Can form a retaining wall or a river bank. Therefore, as compared with the conventional construction method of driving a pile of wood, the construction can be performed easily.

According to the civil construction frame of the present invention,
Since the unit fence-shaped members and the spacing members that are the constituents can be processed in advance in the factory, they need only be arranged or assembled at the construction site. Further, even when assembled in a frame shape, since the unit fence-shaped members and the spacing members are relatively rotatably connected to each other, the unit fence-shaped members can be folded so as to be close to each other. For this reason, even those assembled in a frame shape in advance can be easily transported. Therefore, the civil engineering work frame can be assembled in advance in a factory, transported to the construction site, and installed. As a result, the on-site work can be saved and the overall construction efficiency can be improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 is a perspective view showing an embodiment of a frame for civil engineering work according to the present invention. Further, FIG. 2 is a front view for explaining a connected state of wood, and FIG. 3 is a side view of FIG. 10 is a unit fence-shaped member, and a plurality of pillar materials 1
2, and a stud member 14 disposed between the adjacent pillar members 12,
It is constituted by a bolt 16 and a nut 18 that connect them. The pillar 12 is made of thinned wood, and has a diameter of about 15 cm and a length of 100 to 150 c, for example.
It is about m. The stud member 14 uses the same thinned material as the pillar member 12. For example, the diameter is about 15 cm and the length is 15 cm.
It is about a cm of wood. As shown in FIG. 2, the bolt 16 penetrates and connects the pillar material 12 and the stud material 14 arranged in a fence shape, and is fixed by a nut 18 screwed to the bolt 16.

Reference numeral 20 is a tension transfer material, which constitutes a spacing member. This straining material 20 also uses thinned wood, for example, a diameter of about 15 cm and a length of 80 c.
It is about m. In the stiffening material 20, the unit fence-shaped members 10 are opposed to each other, and the opposed unit fence-shaped members 10 are connected so as to be erected at a predetermined interval.

The unit fence-shaped member 10 and the tension transfer material 20 are
As shown in FIG. 2, the unit fence-shaped member 10 is connected by a connecting means composed of an assembling bolt 22 penetrating the pillar member 12 and the break-through member 20 at the end and an assembling nut 24 screwed to the assembling bolt 22. . In this way, the frame for civil engineering work is formed by the unit fence-shaped member 10 and the tension transfer member 20 which face each other and are divided into a substantially rectangular shape at a predetermined interval.

By the way, as described above, the unit fence-shaped member 10
Since the bridging material 20 and the bridging material 20 are connected by the assembling bolt 22 and the assembling nut 24, the unit fence-shaped member 1
0 and the tension transfer member 20 can relatively rotate about the assembly bolt 22 as an axis. Therefore, as shown in FIG. 3, the unit fence-shaped member 10 is erected (the column member 12 and the tension member 20).
It is possible to change from a state in which and intersect at a right angle) to a state in which the opposing unit fence members 10 are folded in a direction in which they approach each other as shown in FIG.

As described above, the civil construction frame body assembled by the unit fence-shaped member 10 and the tension transfer member 20 can be easily folded, which is convenient for transportation. That is, according to this civil engineering construction frame body, pre-assembled in the factory,
It can be transported to the construction site and installed easily, labor on site can be saved, and overall construction efficiency can be improved.
It is also possible to process the unit fence-shaped member 10 and the tension transfer material 20 to a state before being assembled, transport the processed material, and assemble it on site. In this case, transportation is facilitated, and since the assembling bolt 22 and the assembling nut 24 can be easily assembled, the construction efficiency as a whole can be improved.

The transfer member is not limited to the thinning material as in the present embodiment, but may be a substitute material such as a bolt and a nut. Further, the timber connecting means is not limited to the bolt and the nut, and needless to say, may be any other means as long as it has a function equivalent to that of the present embodiment.

Further specific examples of the frame for civil engineering work will be described. The following are contents of specific examples, and these can be selectively implemented. As a general rule, the diameter of the logs used for the unit fence members 10 and the tension transfer material 20 is 10 to 20 cm, which is a corrosion-prevented product (such as one impregnated with resin). The basic unit of the frame for civil engineering works will be produced by the factory within a transportable size. The number of basic materials (framework for civil engineering) 12 (log) and the standard size of the pillars 12 shall be determined according to the purpose and place of use. The material type and dimensions of the studs 14 for connecting the pillars 12 and the pillars 12 and securing an appropriate interval are the purpose, the place of use,
It shall be determined by the material to be filled inside the space and the standard size. As the material of the sleepers, for example, thinned logs obtained by cutting corrosion-prevented logs, processed products of hard vinyl chloride pipes, stone materials, concrete, pottery products, steel products and the like can be used. When it is necessary to equalize the dimensional diameters of the logs (the pillar materials 12), they are used after being drummed. When the floor log 26 at the bottom is required, instead of the stud member 14, timber equivalent to the tension transfer material 20 is connected and fixed to the pillar member 12 at right angles to the pillar member 12 by bolts and nuts. . By filling the filling log 26 with the filling material, it is possible to prevent the civil engineering work frame from floating and the filling material from leaking to the bottom. This frame body is particularly effective in the case of sinking construction. The number of the pillar materials 12 of the unit fence-shaped member 10 is the diameter of the pillar material 12, the required length and material type of the pillar material, the size and diameter of the earth and stones to be filled in the space, the space volume, the soil quality of the backside sand, the hardness and softness. , With or without suction, purpose of use of the frame (soil retaining wall, waterway wall, flowerbed frame,
Enclosure fence, floor sill ...), etc.

Next, an embodiment of a civil engineering construction method using the civil engineering construction frame of the present invention will be described with reference to the earth retaining frame image diagram of FIG. First, a plurality of timbers (column members 12) are aligned in a fence shape to form a unit fence member 10.
In the embodiment shown in FIG. 6, two unit fence-shaped members 10 are arranged so as to face each other so that the unit fence-shaped members 10 facing each other are set up at a predetermined interval. They are connected by the tension transfer material 20. By connecting in this way, a substantially rectangular unit civil construction frame is formed. Up to this stage, it is manufactured and assembled at the factory. The unit civil engineering construction frame bodies thus formed are connected and extended at a predetermined construction position.
Then, as shown in FIG. 6, a filling material such as earth and sand is filled in the inside of the frame body to construct an earth retaining material.

Further, it goes without saying that the unit fence-shaped member 10 and the transfer member 20 may be connected at the construction site. That is, in the factory, processing is performed before the unit fence-shaped member 10 and the transfer member 20 are assembled. Handing material 2
0 is provided with a through hole for the bolt 16 at a predetermined position in advance. The structural member processed in this way is transported to a predetermined place on the construction site, and the unit fence-shaped member 10 is connected by the bolt 16 and the nut 18 via the tension transfer material 20 to assemble a frame for civil engineering work.

When the construction method of the present invention is applied to a river revetment or canal wall frame, as shown in the image of the canal frame body of FIG. 7, when the rear surface sediment is washed by running water or is sucked out. If this is expected, to prevent this,
(1) The pillar material 12 (log) of the unit fence-shaped member 10 is used as a civil engineering work frame body closely adhering to each other, (2) The suction preventing material on the contact surface between the pillar material 12 of the civil engineering work frame body and the rear surface sand It is possible to take measures such as putting up (soft ground stabilization, suction prevention, scouring prevention material). By the way, the floor sill 28 shown in FIG.
Is formed in the same manner as the above-described civil engineering construction frame, and the frame is filled with rubble and charcoal through a net. Charcoal acts for water purification and is regularly replaced. In addition, the sedimentation frame body 28 is a structure for preventing and stabilizing the scouring of the riverbed as a root work.

Further, as an example of filling the material into the space of the frame for civil engineering work, natural cobblestone, crushed stone, crushed stone, earth and sand are manually or manually stored in the space inside the frame assembled and installed in a predetermined shape at the destination. Fill by machine. The filling depends on the purpose and may be as follows. For stabilizing the hillside and preventing collapse (slope work), it is possible to use earth and sand and gravel that have been generated during floor excavation. In addition, prevent it from leaking out by the suction prevention material. When it is used for earth retaining work or is piled up for revetment of small and medium rivers, the frame of the lower layer and the foundation has a large earth pressure resistance, so the volume of the frame itself is increased. Therefore,
A material having a large size is used as a filling material, and a frame and a filler having a smaller standard than the lower layer frame can be used for the upper layer frame. In addition, when applying a frame for the purpose of living fish in the riverbed,
The space between the stones is increased by using a frame with a wider space between the columns and increasing the size of the cobblestones and the like to be filled inside. A shield plate made of concrete or the like can be used when the soil behind the soil is soft and there is a risk that the soil will leak due to running water or earth pressure. When vegetation such as vegetation, flowering trees, etc. is applied to the frame in consideration of the environment, sandbags with seeds and seedlings are added.

FIG. 8 shows another embodiment of the present invention. 32 is a lath net with ribs. There are a method of hitting ready-mixed concrete by using the lath net 32 with ribs or other equivalent products as an embedded form, and a method of fixing with ready-made concrete panels. On the surface of the cast-in-place or concrete panel 32, the frame for civil engineering construction of the present invention is arranged. In this way, the strength of soil retention etc. can be enhanced by combining with other construction methods. In addition, FIGS. 9 to 12 are explanatory views of the case where the civil engineering construction frame bodies are stacked and used. FIG. 9 shows a case where rectangular frames are stacked along the slope. FIG. 10 shows a state in which trapezoidal frames are stacked. FIG. 11 shows a state in which double rectangular frame bodies are stacked. Further, the parallelogram-shaped frame bodies are stacked in FIG. 12, and the upper stack is smaller in size.

As described above, according to the method of civil engineering and the frame for civil engineering of the present invention, the first feature is that the basic frame of wood (thinned wood processed product) is pre-produced in the factory. , Transporting it to the required place, assembling it to the size standard according to the purpose, filling the space with natural stone, charcoal, earth and sand, etc., and using this as a wall body as an earth pressure resistance element or water purification agent It is possible.

The second characteristic is that if the basic frame is temporarily assembled and manufactured in a factory, the frame can be folded and the package can be made into a compact packing, so that it can be easily and easily transported or loaded and unloaded. .

The third feature is that the filling material for the space inside the frame does not specify its standard, size or material type. That is,
Among the stones generated at the construction site and the materials that can be collected in the vicinity, any material that matches the frame structure and purpose can be used, and the material can be easily procured.

The fourth characteristic is that the frame for civil engineering construction of the present invention is constructed by assembling and constructing log materials with bolts and nuts, so that even if the same frame is combined and constructed, it does not have to be a basic prototype.
It is flexible and easy to apply, and can be improved to a shape that quickly responds to the local topography and slope. 13-
FIG. 17 shows a modification of the frame body of the present invention. FIG. 13 shows that the rectangular frame can be transformed into a parallelogram. Similarly, FIG. 14 shows that the trapezoidal frame body can be deformed into an obliquely crushed state, and FIG. 15 shows that the trapezoidal frame body can be used upside down. 16 shows that the double rectangular frame can be deformed, and FIG. 17 shows that the flat rectangular frame can be deformed into a parallelogram.

The fifth feature is that, according to the civil engineering method of the present invention, it can be used as a general earth retaining wall systematically, and in addition to a sudden sediment disaster, a collapse of the ground and a landslide. It is a construction method that can respond quickly and effectively as an emergency first-aid measure construction method. That is, the following characteristic features of the present invention can be utilized. If the frame material for civil engineering construction of the present invention is assembled locally, a frame body for earth retaining can be easily constructed. The frame is compact and foldable for convenient transportation. No special skill or skill is required for the frame assembly structure and installation work. The installation base of the frame can be installed on a flat or sloping ground. The heavy packing in the inner space of the frame depends on the standard dimensions of the frame structure or the leakage prevention process of the packing to the outside of the frame (for example, currently commercially available nets, perforated ropes, iron plates, sheets, resin, etc. If it is processed with processed goods, etc., the filling material is suddenly or urgently because it can be used regardless of quality or standard as long as it is a material that is easily available locally, regardless of whether it is earth and sand, stone material, or ready-mixed concrete. It is also an effective and economical construction method as a soil retaining measure.

The sixth feature of the present invention is that, in addition to the earth retaining wall, water from concrete or a concrete secondary product, which is mainly constructed by the conventional construction method as a root work for river works or a water control work, is used according to the present invention. It can be applied instead of construction and consolidation methods. Therefore, the advantage is that fish and insects can live better.
It is to be a construction method that is more environmentally friendly and natural. In other words, a wooden frame is installed on the riverbed of rivers and lakes, and the inside of the frame is filled with stones to prevent scouring due to flooding of the riverbed, mitigation of running water in the flood part, and prevention of uneven flow of flowing water. Is effective as a construction method that is friendly to the river environment. By the way, in the conventional method, woodworking sedimentation using wood was used for the purpose of stabilizing the riverbed and solidifying the floor, but it has not been constructed at present. It is considered that the lack of skilled woodworking floor construction and the ease of construction using concrete are the causes. The voids of the stones (cobblestone, cobblestone) that fill the space inside the frame make the fish a habitat for insects, and the water purification effect is naturally performed by the contact between the gravel caused by the distance between the cobblestones. If used together, there is an industrial advantage that purification is promoted more.

The seventh characteristic is that the main material of the frame material for civil engineering construction of the present invention is wood, and unlike other civil engineering materials, it can be incinerated and disposed of, so it is socially friendly even in the problem of treating industrial waste. It is a civil engineering material. In addition, thinned wood can be effectively used, which contributes to the promotion of local forestry and, in turn, helps to develop mountains and forests on the national land. Although various preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and many modifications can be made without departing from the spirit of the invention. That is.
