Description

  The present invention relates to a slope protection structure, and relates to a law foundation foundation that supports the lower side of a slope wall that covers the slope and a law foundation block used to construct the structure.

  In order to prevent the collapse of slopes and the outflow of earth and sand due to wind and rain, and to prevent the weeds from growing over the slopes and harming the landscape, plate or plate-like concrete blocks (legged blocks) are placed vertically and horizontally on the slopes. A protective structure that lays them side by side and constructs a lawn wall is adopted. In this protection structure, the lower side of the lawn wall is held by a lawn foundation structure constructed along the lower side of the slope. At present, this foundation structure is constructed using concrete blocks (legged foundation blocks).

  The general shape of the lawn foundation block is a square or rectangular frame with an open top and bottom, and the slope is in contact with the lower side of the lawn wall on the outer surface of the rear wall located on the slope side when installed. A surface is formed. This inclined surface is an inclined surface in a direction perpendicular to the angle of the slope. The lawn foundation block is installed so as not to cause a step between the top surface of the lawn wall and the top surface of the lawn foundation block.

  In the hollow part of the installed foundation block, a foundation structure with the weight necessary to support the lower side of the method wall is constructed by pouring in-situ concrete from the opening on the upper surface and solidifying it. The

  A slope foundation block is a simple square or rectangular square tube block, except that a sloped surface is formed on the outer surface of the rear wall on the slope side in accordance with the slope of the slope. The position of the lower side is secured and the lower side of the sloped wall laid on the slope is supported to prevent the sloped wall from moving downward along the slope of the slope. In order to secure the structure, cast-in-place concrete is placed in the internal space of the rectangular tube-shaped block to provide a structure having a large weight.

  However, the conventional foundation structure requires a large amount of cast-in-place concrete for construction, and it is necessary to prepare equipment for placing cast-in-place concrete. For this reason, there are problems such as an increase in the construction period and the need to smooth the top surface of the cast-in-place concrete.

  Therefore, this device can reduce the amount of cast-in-place concrete, reduce the work burden required for placing and solidifying the cast-in-place concrete, and shorten the construction period, so that a slope protection structure can be constructed more quickly. The goal is to obtain technical means that can be used.

  The legal foundation block of this invention is composed of a flat square or rectangular frame block 1 (1a, 1b, 1c) whose upper and lower surfaces are open, and a lid block 5 (which closes the upper surface opening of the frame block 1). 5a, 5b, 5c), and the frame block 1 has an inclination of the slope 11 to be protected by at least the outer surface upper part 21 of the rear wall 2 (2a, 2b, 2c) which becomes the slope side when installed. It is formed on the slope in the orthogonal direction.

  In general, the top surface of the slope foundation structure is a sloped surface on the slope side in accordance with the slope of the slope 11, and the anti-slope side is a horizontal plane. Accordingly, the upper surface 51 of the lid block 5 has a reverse shape in which the slope side at the time of installation is an inclined face in a direction parallel to the slope of the slope face and the opposite slope side is a horizontal plane, and the side wall 4 (4a, 4a, The upper edge 41 of 4b, 4c) is also shaped like an inverted shape in which the rear wall 2 side is inclined in a direction substantially parallel to the inclination of the slope.

  The lid blocks 5a and 5b can be structured such that both sides 52 thereof are supported by the side wall upper edges 41 of the frame blocks 1a and 1b to close the upper surface openings of the frame blocks 1a and 1b. In this structure, the heights of the side walls 4a and 4b of the frame blocks 1a and 1b are lower than the heights of the front and rear walls 2 and 3 by the thickness of the lid blocks 5a and 5b. The side 52 has a width dimension supported by the upper edges 41 of both side walls of the frame block.

  For the convenience of construction and transportation, the lid block 5 can be formed by a plurality of divided partial lid blocks 5b. In this case, protrusions 25 and 35 that support the corners 54 of the lid block that are not supported by the upper edge 41 of the side wall of the frame block are provided on the inner wall surface of the frame block 1b.

  As another structure, the lid block 5c can be a drop lid that can pass through the upper surface opening of the frame block 1c.

  In order to allow the lid block 5 to be attached to the frame block 1 without interfering with the front and rear walls 2 and 3 of the frame block, and to minimize the gap between the frame block 1 and the lid block 5, the upper surface 21 of the outer surface is used. The inner surface upper part 22 of the rear wall 2 of the frame block that is inclined in a direction substantially perpendicular to the inclination of the surface is a surface parallel to the inner surface upper part 32 of the front wall 3 on the opposite side of the frame block 1, more preferably. It is preferable to use a surface that forms an inverted letter C with an upwardly draft angle.

  The legal foundation structure constructed by using the legal foundation block of this device is a structure that supports the lower side of the method covering wall 12 formed on the slope, and consists of a pair of the frame block 1 and the lid block 5. Constructed with multiple pairs of Horidome basic blocks. The plurality of frame blocks 1 are arranged in a line along the lower side of the slope with the adjacent blocks in close contact with each other, and the upper surface openings of the frame blocks 1 are closed by the lid block 5. The internal space formed between each frame block 1 and the lid block 5 is filled with an inorganic filler such as earth and sand, stone, concrete block, and cast-in-place concrete.

  The legal foundation structure can be constructed using only the frame blocks 1a and 1b of the legal foundation block of the present invention, that is, without using the lid blocks 5a and 5b. That is, a plurality of frame blocks 1a and 1b are arranged in a line along the lower side of the slope with adjacent blocks in close contact with each other, and the upper surface openings of these frame blocks are replaced with the lid blocks 5a and 5b to make the cast-in-place concrete. The structure is closed by Although the construction method using the lid blocks 5a and 5b is excellent in terms of the construction period, in some cases, it may be possible to reduce the construction cost by closing the upper surface openings of the frame blocks 1a and 1b with cast-in-place concrete. The basic foundation block of this device can be used according to the construction period and cost requirements.

  According to this device, a slope protection structure can be constructed without using cast-in-place concrete. In other words, conventionally, a foundation block was placed along the lower side of the slope, a bottom wall was constructed by supporting the bottom side of the foundation block, and cast-in-place concrete was cast into the hollow portion of the foundation block. In addition, it was necessary to solidify the surface with a trowel.

  On the other hand, according to this device, earth and sand, stones, concrete blocks, etc. collected near the site are placed in the hollow part of the frame block having the same shape as the conventional foundation block placed along the lower side of the slope. After filling, it is possible to construct a protective structure by closing the top opening of the frame block with a lid block and caulking the gap between the frame block and the lid block with mortar.

  Therefore, when constructing a slope protection structure, the equipment and ironing plasterer necessary for placing a large amount of on-site concrete is not required, and it is not necessary to wait for the on-site concrete to solidify. The construction period can be shortened. In addition, the amount of concrete used in the lid block is less than the amount of on-site concrete in the conventional structure, so that the amount of concrete used as a whole can be reduced. And since the upper surface of the constructed foundation structure is formed on the upper surface of the lid block, form a pattern that matches the upper surface pattern of the legally bonded block that forms the method covering wall on the upper surface of the lid block. Therefore, there is an effect that it is possible to obtain a slope protection structure with a more beautiful appearance.

  FIGS. 1 to 5 are views showing a first embodiment of the present invention, and the legal distillation basic block is composed of a pair of a frame block 1a and a lid block 5a. In this specification, the shape of the block will be described with the slope side when the block is installed along the lower side of the slope being the rear side and the opposite side being the front side.

  The frame block 1a is a short square cylindrical concrete block that is almost the same as a conventional square foundation block, and the outer upper surface 21 of the rear wall 2a has an inclined surface in a direction substantially orthogonal to the inclined normal surface. It has become. The side wall 4a of the frame block 1a is lower than the height of the rear wall 2a and the front wall 3a by the thickness of the lid block 5a, and the lid block 5a has its both sides placed on the upper edges 41 of the side walls 4a of the frame block. In this state, the opening on the upper surface of the frame block 1a is closed.

  The rear portions of the frame block 1a and the lid block 5a have a shape that is smoothly continuous with the upper surface of the method covering wall 12. That is, the outer surface upper portion 21 of the rear wall of the frame block is an inclined surface in a direction substantially orthogonal to the inclination of the normal surface, and the rear portion of the upper surface 51 of the lid block 5a is an inclined surface in the same direction as the inclination of the normal surface, The front part is a horizontal plane.

  The lid block 5a shown in the figure is a block having a substantially constant thickness as a whole, and the rear portion of the lower surface is also an inclined surface substantially parallel to the slope, and is generally U-shaped in a side view. Therefore, in the side wall 4a of the frame block 1a on which the lid block 5a is placed, the rear part of the upper edge 41 following the rear wall 2a is an inclined edge in the same direction as the slope of the slope, and the front part is horizontal.

  A through hole 42 with a counterbore in the vertical direction is provided in the side portion of the lid block 5a, and an insert nut 43 is embedded in a corresponding portion of the side wall upper edge 41 of the frame block. In the example shown in the drawing, no opening is provided in the side wall 4a of the frame block, but an opening having an appropriate shape as provided in the conventional method foundation block can be provided.

  Next, with reference to FIG. 5, a description will be given of a lawn foundation structure constructed using the lawn foundation block of the first embodiment. A groove is dug along the lower side of the slope 11 to be protected, and a foundation is appropriately constructed with crushed stone or the like, and then the side walls of adjacent blocks are brought into close contact with each other and the frame blocks 1a are arranged in a row in the groove. Next, the earth and sand are backfilled in the groove so that the frame block 1a is in a half-sunk state, the slope 11 is shaped, the law-attached block 13 is laid vertically and horizontally on the slope, and the lower side is the upper surface of the rear wall of the frame block 1a. A lawn wall 12 in contact with 21 is constructed.

  In parallel with or before and after the laying of the method pasting block 13, a filler such as earth and sand or a concrete lump is put into the inner space of the frame block 1a to be solidified, and mortar is applied to the upper edge 41 of the side wall of the frame block. Both sides of the lid block 5a are placed on the upper edges 41 of both side walls of the frame block, and the upper surface opening of the frame block 1a is closed by the lid block 5a. Then, the bolt 44 is inserted into the through hole 42 and screwed into the insert nut 43 to fix the lid block 5a to the frame block 1a.

  In the structure of the first embodiment (also in the third embodiment described later), the inner surface upper portion 22 of the rear wall 2a of the frame block is also inclined, so that the inner surface and the rear edge 53 of the lid block 5a placed thereon Since a gap is formed between them, mortar 55 is poured into this gap, and further, mortar is applied between the lid block 5a and the inner surface of the front wall of the frame block 1a and caulked to complete the slope protection structure.

  6 to 11 are views showing a second embodiment of the present invention. In this second embodiment, the lid block has a two-part structure for the convenience of block transportation work and installation work. In order to support the two-part partial lid block 5b, The support walls 26 and 36 are formed at the inner center of the front wall 3b, and the rear wall of the frame block so that no gap is generated between the upper surface 22 of the rear wall 2b of the frame block and the rear edge 53 of the lid block 5b. The inner surface upper portion 22 of the front wall 3 is substantially parallel to the inner surface upper portion 32 of the front wall 3 (strictly speaking, the upper portion is a slightly open inclined surface), and a half-moon-shaped opening 45 is provided on the lower side of the side wall 4b. That is, the difference from the first embodiment is that no bolt for fixing the lid block to the frame block is provided.

  Like the frame block 1a of the first embodiment, the frame block 1b is a short rectangular tube-shaped concrete block, and the outer surface upper part 21 of the rear wall 2b is an inclined surface in a direction substantially orthogonal to the inclined normal surface, The side wall 4b is lower than the height of the rear wall 2b and the front wall 3b by the thickness of the lid block 5b.

  The inner surface upper part 22 of the rear wall of the frame block 1b is a surface substantially parallel to the inner surface upper part 32 of the front wall, and its lower part is a downward inclined surface 23 substantially parallel to the outer surface upper part 21 of the outer wall. It is continuous with the lower inner surface 24. At the center in the width direction of the downward inclined surface 23 of the outer wall and the inner surface 33 of the front wall, vertical ridges 25 and 35 projecting toward each other are formed, and the upper surface of the ridge is the upper edge 41 of the side wall. It becomes the same height as the front and rear ends, and is a support surface 26 and 36 that supports the corners inside the lid block divided into two.

  The lid that closes the upper surface opening of the frame block 1b is a partial lid block 5b that is divided into two pieces, and has a generally U-shape in a side view with a substantially constant thickness. The upper edge 41 of the reverse character shape lower than the walls 2b and 3b is provided. Each partial lid block 5b is mounted on the upper edge 41 of the side wall of the frame block, and both corners 54 and 54 of the other side are supported by the support surfaces 26 and 36. It has a shape that closes the opening on the top surface.

  The legal basis structure is constructed in the same manner as the block of the first embodiment. That is, the frame covering wall 12 in which the frame blocks 1b are placed in a half-sunk state along the lower side of the slope 11 to be protected and arranged in a row, and the lower side is brought into contact with the outer surface upper portion 21 of the rear wall of the frame block 1b. Build up. The inner space of the frame block 1b is filled with a filler such as earth and sand or a concrete block, and mortar is applied to the upper edge 41 of the side wall of the frame block, the inner surface upper portion 22 of the rear wall, and the inner surface upper portion 32 of the front wall. The lid block 5b is placed on the frame block 1b. The joint between the frame block 1b and the lid block 5b is caulked with the applied mortar.

  The frame blocks 1a and 1b of the first embodiment and the second embodiment described above are independently constructed in the same manner as a conventional foundation block by closing the upper surface opening with cast-in-place concrete instead of the lid block. It is possible to build a legal foundation structure. Therefore, the legal foundation block of this device has the advantage that a legal foundation structure can be constructed by a method that matches the situation at the site.

  FIGS. 11 to 16 are views showing a third embodiment of the present invention, in which the lid block 5c is a drop lid that can pass through the upper surface opening of the frame block 1c, and the upper edge 41 of the side wall 4c of the frame block 1c. Is different from the first embodiment in that the height is such that there is no step between the front and rear walls 2c and 3c. That is, the upper edge 41 of the side wall 4c of the frame block has an inclined edge substantially parallel to the slope of the slope on the rear wall 2c side, and its rear end is connected to the upper edge of the rear wall 2c without a step, and the front wall 3c side is a horizontal edge. Thus, the front end is an inverted character shape connected to the upper edge of the front wall 3c without a step. This reverse character shape is the same shape as the reverse character shape in the side view of the upper surface of the lid block 5c.

  The structure and operation of the frame block 1c and the lid block 5c of the third embodiment, and the legal foundation structure constructed by the blocks of the third embodiment are other than the differences associated with using the lid block 5c as a drop lid. Since there is no difference, the same reference numerals as those in the first embodiment are attached to FIGS. 11 to 16 similar to FIGS. 1 to 5 in the first embodiment, and the description thereof is omitted.
