本発明は簡便に護岸、法面保護等を為し得る地
表侵食防止用マツトの製造方法に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing pine for preventing ground surface erosion, which can easily be used for bank protection, slope protection, etc.

する等の欠点があつた。 Traditionally, bank revetment or slope protection work involves, for example, leveling and compacting the soil surface to be protected, laying filter material, piling up chestnut stones, and then applying cement mortar to the joints on the top surface while building concrete blocks. was attached. However, this construction method has drawbacks such as being labor-intensive, prolonging the construction period, and requiring skilled professionals to attach the concrete blocks.

ある為多額の経費を要する欠点があつた。 Therefore, in order to eliminate these drawbacks, the idea was to produce mats for preventing surface erosion in a factory by bonding concrete blocks to a sheet material such as woven fabric in advance, and to lay these mats after leveling the slope to be protected. was announced (publication number 51-9135). However, since this invention uses adhesive to bond the concrete blocks and the sheet material, it requires large-scale special equipment to place the concrete blocks at precise intervals and ensure bonding. The drawback was that it was difficult to produce large quantities of pine at the installation site. For this reason, mats manufactured in large quantities at a factory are transported to the site, which has the disadvantage of requiring a large amount of expense as it involves transporting heavy objects over long distances.

作業を必要とする欠点があつた。 Therefore, in order to eliminate these drawbacks, pre-mixed concrete is poured into each concrete block mold of a formwork in which the required number of concrete block molds are connected vertically and horizontally, and then concrete is poured onto the top surface of the uncured concrete. A technology was announced in which a plastic fiber sheet is pressed against the fibers of the sheet, allowing some of the concrete to penetrate between the fibers of the sheet, and solidifying the concrete in this state.
Publication No. 93018). However, this technique has the disadvantage of requiring special equipment and work when pressing the plastic fiber sheet onto the top surface of uncured concrete, as it requires gluing a large number of individual concrete blocks at the same time. Ta. Furthermore, in the process of removing the concrete block from the mold after the concrete block has hardened, it is necessary to turn the formwork upside down, which has the disadvantage of requiring a large-scale inversion demolding machine and work.

のみならずモルタルブロツクを意味することある
ものとする。 The present invention was made in order to solve the various drawbacks of the prior art, and its purpose is to easily create a ground erosion block with strong adhesive strength between concrete blocks and sheets without requiring large-scale special equipment or work. The purpose is to enable efficient mass production, and to reduce costs for manufacturing equipment and transportation. In the present invention, the term "concrete block" refers not only to concrete blocks but also to mortar blocks.

を同時に一体成形する。 The method for manufacturing a block mat for preventing ground erosion of the present invention involves placing a formwork for simultaneous molding of a large number of concrete blocks on a plastic fiber sheet that is water permeable, flexible, and impermeable to earth and sand particles. After that, a concrete or mortar slurry is injected to form a block, and the formed block is cured to integrally form the sheet and concrete block at the same time.

う為である。 As the fiber sheet, it is preferable to use a woven, knitted or non-woven fabric of synthetic fibers or natural fibers having an uneven structure such as a loop or pile shape, or a non-woven fabric of synthetic fibers or natural fibers raised by needle punching treatment. This is to ensure strong and easy bonding between the sheet and concrete or mortar.

したものが好ましい。 Furthermore, if a sheet coated with a water-based adhesive is used as the fiber sheet, only the cement milk in the concrete or mortar slurry to be cast will penetrate into the fiber sheet and disappear (selective water loss). It is particularly suitable because it makes it easier to bond the concrete or mortar and the sheet even more strongly. Preferably, the aqueous adhesive is selected from aqueous emulsion, aqueous paste and cement milk.

Finish with a trowel, etc. to make it smooth. Alternatively, after forming, spread a film sheet, rubber plate, fabric, etc. on the upper end surface, press it lightly with a roller, etc., harden the concrete in this state, and after hardening, remove the spread film sheet, etc. and smooth it. Obtain a smooth block surface. Alternatively, when the molding is in the late hardening state, the surface of the block is cut with a rotating brush, etc.
It is also possible to give it a design quality.

止用ブロツクマツトを簡易に且つ能率良く大量
に製造することができた。Block compressive strength: 300 Kg/cm 2 Adhesive strength : 10 Kg/cm Thus, according to the method of the present invention, highly safe block mats for preventing surface erosion, which have a large adhesive force between blocks and sheets, can be easily and efficiently produced in large quantities. I was able to do that.
本発明方法によれば次のような利点が得られ
る。 According to the method of the present invention, the following advantages can be obtained.
本発明技術は、製造設備の主なものが型枠のみ
であり、また型枠も鉄又はFRP、木材等任意の
材料を格子状に構成するだけで良く極めて簡単で
あり、設備コスト及び保守コストが極めて低廉で
ある。また、製造方法も簡単な流し込みによるも
ので極めて容易でコストが低減され、脱型は型枠
を上方に引き上げるだけであるので、上下反転脱
型を必要としない上に接着面に殆んど力が加わら
ない為、不良品が少くなり、養生、脱型時間も短
縮され生産性及び強度が向上するばかりではな
く、型枠の持込により施工現場で製造することも
可能となり、輪送コストも極めて低廉となる。ま
た、表面に意匠を自由に施し得る為、景観を必要
とする場所にも好適に用いることができる。 In the technology of the present invention, the main manufacturing equipment is only the formwork, and the formwork can be made of any material such as iron, FRP, wood, etc. in a lattice shape, which is extremely simple, and the equipment cost and maintenance cost are reduced. is extremely inexpensive. In addition, the manufacturing method is extremely easy and cost-reduced, as it is a simple pouring process, and demolding is done by simply pulling the mold upwards, so there is no need to flip the mold upside down and there is almost no force applied to the bonding surface. This not only reduces the number of defective products and shortens curing and demolding time, improving productivity and strength, but also enables manufacturing at the construction site by bringing in formwork, which reduces transport costs. Extremely cheap. In addition, since designs can be freely applied to the surface, it can be suitably used in places where landscape is required.
本発明の広汎な精神と視野を逸脱することな
く、本発明の種々の変更な修整と変更が可能なこ
と勿論である。 It will be understood that various modifications and changes may be made to the invention without departing from its broad spirit and scope.
