Abstract
Description
[Technical field]
[0001] The present invention relates to partial burial in the ground, erecting posts and weeds. [Background technology]
[0002] Prefectural roads, rivers, farmland, farm roads. Slopes are constructed on residential land. As these slopes are formed of soil and sand, weeds grow on them. Managing weeds on the slopes requires unnecessary work hours, lawnmowers, and herbicides. Heavy rains cause landslides on the slopes. Rivers often experience natural disasters, such as overflowing due to rising water levels. There is a demand for structures that can reduce the spread of damage caused by linear rain bands. Wooden buildings are vulnerable to collapse due to earthquakes, fires, tsunamis, mountain tsunamis, and flooding. [Prior art documents] Publicly known
[0003] Not only in agricultural disasters in Japan, but also in other cases, slope reconstruction work designs mainly use block stacking methods and concrete retaining walls within formwork, but due to the high construction costs, construction does not extend to the upper paddy field ridges. Therefore, the above-mentioned methods are used up to the lower part of the foundation that supports the slope, but the upper part is mainly slope construction using soil and sand, and weeds are currently dealt with using grass cutters and herbicides. In the case of rice cultivation, grass is cut at least three times from planting to harvest. The spraying of herbicides causes the slopes to become rough, which is a cause of bullying for farmers. Weeds and the intrusion of wild animals are still left unattended. Summary of the Invention [Problem to be solved by the invention]
[0004] The present invention focuses on slopes along the sides of roads, rivers and farmland, and aims to provide a method for managing weeds on the slopes, and by utilizing the slopes effectively, to financially support the interests of landowners and slope issues, and to bring benefits to users. A method is known in which weeds are prevented from growing above ground by suppressing them with heavy materials such as concrete, steel or raw wood lumber, rather than treating the growth of weeds with herbicides or grass cutters. Electric poles used by power companies, communication companies and utility poles are primarily cylindrical, and advertising agencies use square sign posts, but neither of these can support the stress of the soil above. Therefore, a long flat panel shape is required. Road sign posts also have the same tendency to protrude above ground. [Means for solving the problem]
[0005] As a means for solving the above problems, the present invention buries long flat concrete panels 5m long, 1m wide, and 10cm thick in the ground in a straight line along the boundary line at the bottom of the slope. The burial depth is set to 1 / 5 of the total length (approximately 1m), and the burial depth is dug according to the site conditions to erect the panels, and the buried ground is firmly secured up to the burial line of the long flat panels. When the faces of the long flat panels are erected in a horizontal line after the ground is solidified, a slope space is created between the previous ridge and the slope. If this space is backfilled, the ridge and slope disappear. The backfilled land becomes a paddy field, and the paddy area is expanded. If the slope space is not backfilled, it can be used for a water storage tank, etc. If the long flat panels are arranged in a horizontal line with a length of 30m, and the aboveground part is 4m and the buried part is 1m, a large screen 30m wide and 4m tall is formed on the lower paddy side. By using this screen for advertisements, promotions, educational bulletin boards, etc., if this area becomes a model area for slope utilization, weed management will become unnecessary not only in prefectures in Japan but also in other areas. When backfilling the area for erecting long flat panels, it is important to ensure that stones, soil, and tightening are carried out. If the site is soft, concrete should also be considered. If the contractor is unable to erect long flat panels, how to deal with weeds depends on the material of the long flat panel, concrete, steel, and raw wood, as mentioned above, which has weight. By simply placing long flat panels on land where weeds grow, it is possible to deal with the growth of weeds. The length, width, and thickness of the long flat panel panels to deal with weeds can be increased or decreased depending on the site conditions, allowing for a reduction in the amount of material required. Effect of the Invention
[0006] When erecting long flat panels in a straight line along the boundary line at the bottom of the slope, if the ridge and slope disappear, soil management, i.e. weed management, is not necessary on the ridge and slope, which is helpful for farmers. After erection, the surface that appears on the ground (the paddy field side below the rice terrace) will be formed as a single screen with the length of the boundary line and the length that appears on the aboveground part of the long flat panel, so it can be used as an advertising board, a notice board for public notice, an educational sign, a road sign, etc. Furthermore, the location of the long flat panel to be installed in the river must be discussed thoroughly with the river administrator and the residents regarding the location of the large-scale long flat panel installation, the shape and size of the panel. If it is not possible to install long flat panels to suppress weeds, it is better to adopt a shape that is suitable for the site without being limited by the length, and to use a combination of concrete, wood, steel plates, non-metallic materials, etc. For example, one method is to place lightweight materials and then hold them down with sandbags. BEST MODE FOR CARRYING OUT THEINVENTION
[0007] The construction of long flat panels (concrete material) arranged in a horizontal line on the boundary line at the bottom of the slope of the present invention will be explained below with reference to the drawings. Figure 1 shows a cross-section of a rice paddy terrace, where a slope 1 is formed in a rice paddy 16 by a ridge on the paddy side 4, a ridge slope side 5, and a ridge apex 6.
[0008] ^ Figure 2 shows the construction of the long flat concrete panels 8 in a horizontal line on the boundary line 3 at the bottom of the slope of the rice terrace in Figure 1, and is a cross-sectional view of a portion of the panel. As shown in the figure, after the construction of the long flat concrete panels 8, a slope space 11 is formed on the paddy field side of the aboveground part 9. This slope space 11 is an important element and can be used according to the landowner's purpose. If the slope space 11 is backfilled, the paddy field can be expanded, the yield of the product can be increased, and the ridges and slope 1 will disappear, making weed management unnecessary. When backfilling the slope space 11, it is important to compact the soil from the buried part 10 of the long flat panel 8 to the paddy field upper GL. It is also possible to use the slope space 11 without backfilling it, so the landowner and the user can make effective use of the method.
[0009] Figure 3 is a cross-sectional view of a long flat concrete panel 8 erected in a straight line on the lower boundary line 3 of the slope, and the slope space 11 backfilled 12. In the paddy field 16, a slope is formed at the paddy field side 4, the slope side 5, and the ridge top 6. The paddy field 16 is formed by removing the ridges 4, 5, and 6 and the slope 1, and the area that occupies the slope is expanded, as described in Figures 2 to 6. In Figure 2, the long flat panel 8 is erected vertically in a straight line on the lower boundary line 3 of the slope to receive soil and sand from the paddy field side 4. The buried part that is excavated from the lower boundary line 3 of the slope on the upper paddy field side can be excavated to a depth of 1m or less, but by excavating the ground vertically so as not to extend into the lower paddy field side 4 as much as possible, the amount of excavation work on the lower paddy field side can be reduced. The drainage function utilizes the joint space.
[0010] Figure 5 is a front view of a long flat concrete panel 8 buried about 1m underground in a straight line on the boundary line at the bottom of the slope, as seen from the lower paddy field. If the length of the paddy field boundary line is 30m, for example, and the long flat concrete panel is 5m above ground, a large screen 30m wide and 5m tall will be formed vertically. This long flat panel can be dismantled from the site after construction work is completed and reused in other places.
[0011] Figure 6 is a perspective view of a long flat concrete panel, and the length, width, and thickness are shown in the figure. The standard dimensions are 6m long, 1m wide, and 10cm thick, with an effective height of 5m above ground and 1m buried underground. Without being limited to these standard dimensions, long flat concrete panels are manufactured to meet on-site needs for both small and large-scale construction projects. When used in large-scale construction projects, support wires and anchors must be installed to prevent the long flat concrete panel from tilting. Although not shown in Figure 6, reinforcing bars and metal mesh are naturally installed inside the long flat concrete panel. [Brief description of the drawings]
