Description

  The present invention relates to a method for constructing a honeycomb structure in which a honeycomb solid reinforcing material having a honeycomb structure made of a strip material made of a plate-like or net-like polymer material is filled with a filler such as earth and sand or crushed stone.

  A honeycomb-shaped three-dimensional reinforcing material having a honeycomb structure made of a strip material made of a plate-like or net-like polymer material has been known, and a honeycomb structure in which this honeycomb-shaped three-dimensional reinforcing material is filled with a filler (hereinafter referred to as a honeycomb structure). Structures filled with fillers in the shape of three-dimensional reinforcing materials are referred to as “honeycomb structures”). They have been used for ground reinforcing materials, road base materials, sidewalk foundation materials, temporary roads, and retaining wall materials (patents) Reference 1).

  In general, a ground reinforcing structure using a honeycomb structure is used as a lower support for concrete structures, roads, railways, and the like. Patent Document 2 presents an example in which a ground reinforcing structure using a honeycomb structure is used as a road bed of a railway or the like.

  By the way, for the construction of the honeycomb structure, in order to fix the honeycomb-shaped three-dimensional reinforcing material, which is a flexible material, at the construction position, it has been necessary to install a form using wood or the like so as to surround the construction range. This installation work for the formwork was much more laborious than the subsequent installation work for the honeycomb structure.

  In addition, after the honeycomb structure was installed, the formwork had to be removed while refilling the periphery of the honeycomb structure. If the removal was neglected, in the future, the wood forming the formwork in the soil would cause problems such as decay and sinkage, causing poor construction. Furthermore, this series of mold installation and removal work is very time-consuming work, and it has become a bottleneck for the honeycomb structure installation work that should be advantageous to be able to easily construct a support such as a structure.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view of a honeycomb three-dimensional reinforcing material 1 used for the present invention before expansion. The honeycomb three-dimensional reinforcing material 1 is obtained by bonding a plurality of high-density polyethylene strip materials 2 at bonding sites 4 at regular intervals. The honeycomb-shaped three-dimensional reinforcing material 1 is stretched in the stretching direction 5 to form a honeycomb-shaped cell structure.

  The strip material of the honeycomb-shaped three-dimensional reinforcing material 1 is preferably provided with holes 3 in order to improve drainage. The hole may have any size or shape, but a circular shape having a size of about 1 cm is particularly preferable. Furthermore, it is better that the number of holes is large, but if the number is too large, the strength of the strip material is lowered, so that the number should not exceed 40% of the area of the strip material. Further, the holes may be arranged in series or in a staggered manner.

  FIG. 2 is a perspective view when the honeycomb three-dimensional reinforcing material having holes in the strip material shown in FIG. 1 is stretched. When the honeycomb-shaped three-dimensional reinforcing material 1 is stretched, honeycomb-shaped cells 6 are formed. By filling the cells 6 with the filler 7 and compacting, a rigid honeycomb structure is formed. If there is a hole in the strip material, the water in the cell can move not only in the vertical direction but also in the horizontal direction, improving drainage.

  FIG. 3 is a perspective view of a support (L-type) used for constructing a honeycomb structure using the honeycomb-shaped three-dimensional reinforcing material of the present invention. The support 8 has an L-shaped cross-section structure in which each side of two rectangular plates is joined. There is also a hole 9 for draining water inside the plate. A reinforcing member 10 is held at the center of the support 8. The reinforcing member 10 is inserted into the reinforcing member connecting slit 11 attached to the support member to increase the strength of the L-shaped support member.

  The two rectangular plates constituting the support may not be rectangular, and may be square, trapezoidal or triangular. In FIG. 3, the holes 9 for draining water are depicted as two large square holes. However, the holes 9 need not be large holes as long as they have drainage properties. Good. Further, the shape of the hole is not limited to a square shape, and may be a circle, an ellipse, a triangle, or a polygon.

  The reinforcing member 10 is not limited to a triangle as shown in FIG. 3, but may be a rectangle or a rod as long as the L-shape of the support can be maintained. In addition, a large number may be provided in only one place. Further, the reinforcing member may be of a type that is connected to the support when in use as in this example, or may be in a state of being connected to the support in advance.

  FIG. 4 is a perspective view of a support (inverted T type) used for constructing a honeycomb structure using the honeycomb-shaped three-dimensional reinforcing material of the present invention. The support 8 may have an inverted T-shaped cross section in which one side of a rectangular plate in contact with the honeycomb structure end side surface and a surface of the rectangular plate in contact with the ground are combined. FIG. 4 shows an example in which a rectangular plate has a large number of small holes.

  The support of the present invention may be made of any material as long as it does not rot in the soil. Desirable are corrosion-resistant metals such as plastic and stainless steel. More desirable are plastics such as polyethylene and polypropylene.

  FIG. 5 is a construction example of the support (L-type) of the present invention. Supports are lined up so as to border the construction range of the honeycomb structure. It is desirable to fix the arranged support tools with anchor pins or piles to the extent of temporary fixing. The reverse T type is also arranged in the same way.

  FIG. 7 is a construction example of a conventional wooden frame to be constructed on site. The wooden pile 13 is driven at a constant interval, and the wooden board 12 is fixed there with a nail or the like to construct a formwork. It is a construction method that takes more time than the case of using the support of the present invention.

  FIG. 6 shows an example in which the honeycomb-shaped three-dimensional reinforcing material 1 is laid on the inner side of the support 8 of the present invention, and the honeycomb-shaped three-dimensional reinforcing material 1 is filled with a filler 7 such as earth and sand or crushed stone. Thereafter, the support 8 is embedded together with the honeycomb-shaped three-dimensional reinforcing material 1.

  FIG. 7 shows an example in which after installing a wooden frame of a conventional construction method, a honeycomb-shaped three-dimensional reinforcing material 1 is laid inside, and the honeycomb-shaped three-dimensional reinforcing material 1 is filled with a filler 7 such as earth and sand or crushed stone. After installation of the honeycomb structure, the wooden board 12 and the wooden pile 13 are removed. If it is not removed, the wooden frame will rot in the soil, and there is a risk of causing problems such as subsidence in the future.

  When building a honeycomb structure filled with fillers such as earth and sand and crushed stone in a honeycomb-shaped three-dimensional reinforcing material, it eliminates the hassle of wooden formwork installation work and formwork removal work that were performed each time on site. Thus, the installation work of the honeycomb structure can be performed more easily.
