Description

  The present invention relates to a method for manufacturing gabions, and in particular, makes it easy to lift stone-clad gabions with cranes, etc., prevents deformation, and manufactures and stores them outside construction sites such as revetments and riverbeds. It is related to gabion that can be shipped in accordance with the ordering and progress status.

  In recent years, river rehabilitation with a concrete structure on the three sides of the revetment and river bed has been reviewed, and a natural environment structure that can coexist with living things has been adopted in river rehabilitation.

  These construction structures used for the revetment and riverbed are used for the revetment and riverbed outside the tight river where the river is meandering and the flow of sediment is severe, so that a stable construction structure can be obtained. Most of the water flow is well-structured, and it is filled with cobblestones and chestnuts deposited in the riverbank etc. in the gabion made of a rectangular parallelepiped or cylindrical shape, and laid on the bank of the revetment, or the riverbed It is laid and constructed.

  In river revetments and riverbeds with such gabions, plants and insects are easy to vegetate and deposit to prevent the loss of sediment that absorbs and purifies pollutants in the water. In order to promote natural water quality purification and habitat of animals and plants, aquatic plant vegetation, etc., by constructing a structure that positively introduces and deposits earth and sand, or fills contact members to purify water. In order to restore the environment, soil and sand must be deposited in the gaps between cobblestones and chestnuts packed in gabions in order to facilitate plant and insect vegetation on the laying surface of gabions.

  Conventional laying of gabions requires a lot of manpower for work at the site and is suitable for the vicinity of the site because a net fence is installed on the slope and cobblestones and chestnuts are packed in the mesh fence. If there was no quarry, there was a problem in the procurement of cobblestones and chestnuts at the site.

  In order to deal with such problems, as a method of laying a gabion, a gabion assembled at a place different from the laying place is filled with cobblestones and chestnuts, covered with a lid net, and the gabion is lifted with a crane and trucked. It is transported to the current lift and then lifted again with a crane at the site and lowered to the laying site. However, in this method, there is a problem that the gabion is deformed by the weight of the cobblestones and chestnuts inside when it is lifted by a crane, so it is necessary to make the gabion frame strong, It was necessary to use a strong but expensive turtle shell wire mesh instead of an inexpensive diamond wire mesh.

  A gabion or chestnut stone is packed into a net fence assembled at a place different from the laying place to make a gabion, and when the gabion is moved to the laying place, it is prevented from being deformed even if it is lifted by a crane or carried by a truck. This is the problem that the invention tries to solve.

  As a means for solving the problem, it is necessary to develop a gabion that is easy to move and install without being deformed when it is lifted by a crane or the like even if the framework of the net is not strengthened.

  Conventionally, as a method of laying the gabion 1, the gabion 1 assembled at a place different from the laying place is filled with cobblestones or chestnuts 5, covered with a lid net 3, and the gabion 1 is lifted with a crane and then on a truck. The method of transporting to the site, and then lifting the crane again at the site and lowering it to the laying site has been adopted. However, when the crane is lifted by the crane, the gabion 1 is deformed by the weight of the cobblestone or chestnut 5 inside. In order to prevent this, it is necessary to make the frame of the gabion 1 strong. However, in the present invention, when cobblestone or chestnut stone 5 is put into a predetermined thickness below the gabion 1, the concrete flows into the interior. The cobblestones and chestnuts 5 are integrated, and further, the cobblestones and chestnuts 5 are integrated by freezing, so that the gabion 1 is not deformed even when lifted by a crane during movement. Therefore, it is not necessary to strengthen the framework of the net cage 2, and it is possible to use a normal diamond wire net instead of the turtle shell metal net, and the gabion can be made inexpensive and easy to move. Furthermore, if the gabion 1 is manufactured and stored according to the construction scale, it can be shipped at the time of construction ordering or according to the progress of the work. Furthermore, if sand and sand 7 is put in the gap between the cobblestones and chestnuts 5 packed in the gabion 1, plants and insects can be easily vegetated on the laying surface of the gabion, natural water purification, animal and plant habitat, aquatic plant vegetation, etc. It has various remarkably various effects, such as being effective in reviving a natural environment that promotes.

  In the present invention, as the best mode for solving the problem, in a gabion formed by clogging cobblestones and chestnuts in a net fence at a place different from the laying place, cobblestones and chestnut stones are put in a predetermined thickness below the gabions. It is a gabion made by injecting concrete at the time and integrating the cobblestones and chestnuts inside, and then clogging the tops with cobblestones and chestnuts and closing the top surface. Furthermore, in a container with a draft toward the top It is a gabion that is made by integrating the cobblestone and chestnut inside, by putting the net cage in, putting the cobblestone and chestnut in the net cage and covering the net, further putting water in the container and freezing, Furthermore, by putting earth and sand into the gap between the cobblestones and chestnuts placed in the net cage in the container, adding water and freezing, it presents a gabion made by integrating the internal cobblestones, chestnut stones and earth and sand. To do.

  It is a container 4 having a size capable of storing a predetermined net cage 2 serving as a gabion 1, and the container 3 is provided with an appropriate draft angle upward from the bottom. Cobblestones and chestnut stones 5 are packed into the mesh cage 2 in the container 4 to a predetermined thickness. At this time, vibration may be applied so that cobblestones and chestnuts 5 can be filled evenly. Next, the concrete 8 flows between the cobblestones and chestnuts 5, the cobblestones and chestnuts 5 are integrated with the concrete 8, and the cobblestones and chestnuts 5 are newly filled thereon, and the upper surface of the net cage 2 is covered with the net lid 3. Closed to be gabion 1. In addition, the thickness which integrates the cobblestone or the chestnut stone 5 with the concrete 8 is not particularly limited, and the gabion 1 may not be deformed when the gabion 1 is lifted by a crane.

  It is a container 4 having a size capable of storing a predetermined net cage 2 serving as a gabion 1, and the container 3 is provided with an appropriate draft angle upward from the bottom. Cobblestones and chestnut stones 5 are packed into the net cage 2 in the container 4. At this time, vibration may be applied so that cobblestones and chestnuts 5 can be filled evenly. The upper surface of the net cage 2 filled with cobblestones and chestnuts 5 is covered with a net lid 3 and closed to form a gabion 1. Next, an appropriate amount of water 6 is put in the container 4, the water 6 is frozen and the internal cobblestones and chestnuts 5 are solidified and integrated with ice, and the gabion 1 is deformed even if it is lifted by a crane when the gabion 1 is moved. I'm trying to keep things from happening. The amount of water 6 to be frozen and the freezing method are not limited, and a predetermined amount of cobblestone or chestnut 5 may be integrated by freezing and the gabion 1 does not have to be deformed when lifted by a crane. In this embodiment, a square gabion is described. However, the gabion is not limited to a square shape, and may be a cylindrical shape or a polygon depending on the application, and the shape of the gabion is not limited.

  A cobblestone or chestnut stone 5 is packed in a net cage 2 in a container 4 of a size that can accommodate a predetermined net cage 2 to be a gabion 1 with sand and sand 7 appropriately. The upper surface of the net cage 2 filled with cobblestone, chestnut stone 5 and earth and sand 7 is covered with a mesh lid 3 and closed to form a gabion 1. Next, an appropriate amount of water 6 is put into the container 4 and frozen, and the cobblestone, chestnut stone 5 and earth and sand 7 inside are solidified and integrated with ice, and the gabion 1 is deformed even if it is lifted by a crane when the gabion 1 is moved. So that there is no.

  As described above, according to the present invention, in the gabion 1 in which the net cage 2 is filled with cobblestones and chestnuts 5 in a place different from the laying place, the cobblestones and chestnut stones 5 are added to a predetermined thickness below the gabion 1. The gabion 1 is made by injecting the concrete 8 and integrating the cobblestones and chestnuts 5 inside, and then capping the cobblestones and chestnuts 5 in the upper part and closing the upper surface. Put the net 2 in the container 4, put the cobblestone or chestnut 5 in the net 2, cover the net 3, and put the water 6 in the container 4 to freeze. 5 is integrated with the gabion 1 and, further, by putting earth and sand 7 in the crevice between the cobblestones and chestnuts 5 put in the net cage 2 in the container 4 and further adding water 6 and freezing, Since it is a gabion made by integrating cobblestone, chestnut stone 5 and earth and sand 7 together, traditionally how to lay gabion 1 The gabion 1 assembled at a place different from the laying place is packed with cobblestones and chestnuts 5 and covered with a lid net 3, and the gabion 1 is lifted with a crane and carried to the site by a truck. The method of lifting again with a crane and lowering to the laying place was taken, but in this method, there is a problem that the gabion 1 is deformed by the weight of the cobblestone or chestnut 5 inside when it is lifted with a crane, in order to prevent it Although it was necessary to make the frame of the gabion 1 strong, in the present invention, when the cobblestone or chestnut stone 5 is put into a predetermined thickness below the gabion 1, the concrete 8 is introduced to integrate the cobblestone or chestnut stone 5 inside. In addition, the cobblestone and the chestnut 5 are integrated by freezing, so that the gabion 1 is not deformed even if it is lifted by a crane during movement. Therefore, it is not necessary to strengthen the framework of the net cage 2, and it is possible to use a normal diamond wire net instead of the turtle shell metal net, and the gabion can be made inexpensive and easy to move. Furthermore, if the gabion 1 is manufactured and stored according to the construction scale, it can be shipped according to the progress of the work. Furthermore, if sand and sand 7 is put in the gap between the cobblestones and chestnuts 5 packed in the gabion 1, plants and insects can be easily vegetated on the laying surface of the gabion, natural water purification, animal and plant habitat, aquatic plant vegetation, etc. The industrial applicability is extremely large, such as being effective in reviving the natural environment that promotes the environment.
