Abstract

<P>PROBLEM TO BE SOLVED: To provide a structure for promoting vegetation of a slope face for a bag for a sandbag itself for forming the slope face. <P>SOLUTION: This bag for a sandbag for constructing a slope face, is formed in a hollow cubic shape, by serially continuing four peripheral surfaces of a front part 2, a back face part 3 and both left-right side surface parts 4 on the peripheral edge of a bottom surface part 1. The bag for the sandbag is characterized by using a texture of a mesh of the size of a degree of not falling the soil in the bagg off the bag, in construction or in the middle of carrying, being woven into a square of 2 to 3 mm by textile fiber on the texture for forming the front part 2. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

The present invention relates to a sandbag bag used when building a slope, and is characterized in that a mesh fabric is used for the front portion of the sandbag forming the slope.

As the sandbag bag forming the slope, a bag is used which is formed in a cubic shape by continuously connecting the four peripheral surface portions of the front surface portion, the back surface portion, and the left and right side surface portions on the periphery of the bottom surface portion ( For example, see Patent Document 1).
It is also well known in the art to use a planting bag that facilitates plant growth on the slope to be constructed (see, for example, Patent Document 2).

JP 2003-105734 A JP-A-7-173836

The sandbag bag of the above-mentioned Patent Document 1 uses a normal cloth that is durable and clogged on the bottom surface, the front surface, the back surface, and the four circumferential surfaces formed by the left and right side surfaces. There was no structure to promote slope vegetation.
Further, the planting bag of Patent Document 2 is such that plant seedlings are planted in soil stuffed in a bag sewed with synthetic resin fibers. No measures were taken to promote vegetation.

From the above, the problem to be solved by the present invention is to provide a sandbag bag itself that forms a slope with a structure that promotes vegetation on the slope.

Therefore, in order to solve the above-mentioned problem, the present invention is a method in which the front surface, the back surface, and the four side surfaces of the left and right side surfaces are continuously formed on the periphery of the bottom surface to form a hollow cube shape. In the sandbag bag for surface construction, the sandbag bag is characterized in that a mesh fabric woven with approximately 2 to 3 mm square of woven fiber is used as the fabric forming the front portion.

The sandbag bag of the present invention formed as described above has, for example, a seed, a fertilizer, and preferably some cultivated soil sandwiched between two thin substrates such as a non-woven fabric, and this substrate is placed on the back surface of the front portion. After storing the appropriate soil in the bag, the front part formed of the mesh fabric is directed to the front side and stacked in the horizontal and vertical directions of the slope and used.
Since the front part formed of the mesh fabric is superior in water permeability and air permeability compared to the other side part, it forms a slope suitable for plant growth.

Since the sandbag for the sandbag according to the present invention is formed of a mesh fabric woven with a woven fiber in a square of about 2 to 3 mm, the soil contained in the bag is transferred from the front to the middle during transportation or construction. It can prevent spilling out.
Since the upper surface is open, when the sandbag according to the present invention is obliquely stacked up and down along the slope N as shown in FIG. The top surface of the bag is forward, and the germination and growth of the plant will be promoted from the top surface of the bag that is slightly exposed, but the formation of the part is an example of using the sandbag according to the present invention. It is not included in the constituent elements of the invention. Moreover, it is arbitrary whether it is set as the structure which closes the opening | mouth of a bag like the said prior art example.

A sandbag bag for slope construction, which is formed into a hollow cube shape by continuously forming four circumferential surface parts consisting of a front surface part, a back surface part, and left and right side surface parts on the periphery of the bottom surface part. A sandbag bag characterized in that a mesh fabric woven with a woven fiber into a square of about 2 to 3 mm is used for the fabric forming the part.

The drawings show an embodiment of the present invention. FIG. 1 is a perspective view of the sandbag bag according to the first embodiment of the present invention. FIG. 2 shows the number of reinforcing belts provided around the bottom, the side, and the bottom. 3 is a front view of the second embodiment, FIG. 4 is a plan view of the second embodiment, FIG. 5 is a side view of the second embodiment, and FIG. FIG. 7 is a schematic view showing an example of construction using the sandbag bag according to the present invention.

In Example 1 and Example 2, 1 is a bottom part cut into a square, 2 is a front part, 3 is a back part opposite to the front part 2, 4 is a left and right both sides connecting the front part 2 and the back part 3. It is a face part.
The sandbag 5 is formed in a hollow cubic shape by continuously connecting the four peripheral surfaces 2, 3, and 4 on the periphery of the bottom surface portion 1.

For the fabric forming the front portion 2, a mesh fabric woven with approximately 2 to 3 mm squares of woven fibers is used, and for the other portions, a strong and clogged normal fabric is used.
The size of the mesh that forms the front portion 2 may be slightly larger or smaller than 2 to 3 mm square, but is small enough to prevent the soil contained in the bag from spilling and having water permeability and air permeability. Is preferred.

In the figure, 5 is a reinforcing belt which is sewn to the bottom surface portion 1 and the four circumferential surface portions 2, 3 and 4 with appropriate intervals, and 6 is sewn to the bottom surface portion 1 and the left and right side surface portions 3 and 4. The two hanging belts 5, which form a ring at the upper part, 5 ′ are reinforcing cloths of the hanging belt 6, and 7 is a suture line for sewing the four sides of the bottom surface portion 1 and the four circumferential surface portions 2, 3, 4 respectively. It is. In this embodiment, worship sewing, which is commonly called, is employed for stitching to the edge of each part.

In the illustrated embodiment, the outer portion of the bottom portion is 840 mm square and the depth is 1200 mm. However, when the present invention is implemented, the dimensions of each portion may be changed depending on the application. Also, the fibers that weave the mesh can be changed to, for example, sufficiently strong synthetic fibers or natural fibers that are easily corroded.

It is a perspective view of Example 1 of a sandbag bag according to the present invention. It is a front view of Example 2 which increased / decreased the number of the reinforcement belts with which a bottom part periphery, a side surface, and a bottom face are equipped. 6 is a rear view of Example 2. FIG. 6 is a plan view of Example 2. FIG. 6 is a side view of Example 2. FIG. 6 is a bottom view of Example 2. FIG. It is a schematic diagram which shows an example of the construction of an Example.
