Asphalt pine is a mixture of asphalt, stone powder (filler), sand, and crushed stone that is precast on land to form a pine shape. As shown in Figure 2, asphalt pine 1 is used for the foundation slope of a hydraulic structure. This method is used to prevent soil leakage, outflow, and scouring of the embankment by laying it on the tip of the pine and using the watertightness and flexibility of the pine, and it can be applied to the bottom of gravity-type structures to improve the sliding resistance of the embankment. An increasing number of construction methods are being used. Figure 2 shows the case of leakage prevention of buried soil, in which 3 shows the embankment body, 4 shows the embankment as its foundation, and 5 shows the concrete block that protects the slope of the embankment 4.

あるが、施工の容易性から見れば(a)が一番であ
る。 By the way, the joints when the asphalt mats 1 are laid out will differ depending on the conditions of the construction site, but as shown in Fig. When mastic is poured into the joint, (c) when a joint board is placed on top or under the butted joint, etc., each has its advantages and disadvantages, but from the viewpoint of ease of construction, (a) is the best. It is.

目部の密着性を高めるようにしている。 However, the overlapping seam (a) also has the disadvantage of being weaker in strength than other joints. Therefore, in Japanese Patent Publication No. 50-21778, an asphalt-based soft material is sandwiched between the ends of asphalt mats, and the joints are then crimped to improve the adhesion of the overlapping joints.

The method disclosed in the above-mentioned Japanese Patent Publication No. 50-21778 is to press asphalt and an asphalt-based soft material as the joint medium, and this pressing requires a step of rolling with a roller or the like.
It was extremely troublesome and time-consuming.
本発明の目的は前記従来例の不都合を解消し、
転圧などの圧着作業や接着剤を用いることなしに

の接合工法を提供することにある。 The purpose of the present invention is to eliminate the disadvantages of the conventional example,
To provide an asphalt pine joining method that can be easily and effectively constructed without using pressure bonding work such as rolling pressure or adhesive.

In order to achieve the above object, the present invention provides a method for disposing a band of a water-swellable composition along the edge of the asphalt mat between the ends of the asphalt mat when the ends of the asphalt mat are overlapped to form a seam. However, the gist of this method is to sandwich this band directly between the ends of the asphalt mats.
本発明によれば、アスフアルトマツト端部間に
挟設される帯体は地中若しくは水中の水分を吸収
して膨潤する。これにより、外部から圧着しなく
てもアスフアルトマツトとの接合は密となり、完
全な水密構造が得られる。
According to the present invention, the band sandwiched between the ends of the asphalt pine absorbs moisture in the ground or water and swells. As a result, the bond with the asphalt mat is tight even without external pressure bonding, and a completely watertight structure can be obtained.
以下、図面について本発明の実施例を詳細に説
明する。
Embodiments of the present invention will be described in detail below with reference to the drawings.
第１図は本発明の接合工法の実施例を示す斜視
図で、図中１，１は前記のごときアスフアルトマ
ツトを示す。 FIG. 1 is a perspective view showing an embodiment of the joining method of the present invention, and in the figure, numerals 1 and 1 indicate asphalt mats as described above.

同士を上下に重ね合わせて継目を形成するが、そ
の際マツト１の縁部に沿つて水膨潤性組成物の帯
体２を配設し、この帯体２をマツト１，１間に挟
設するようにした。 In order to join the asphalt pine 1, the ends are overlapped vertically to form a seam. At this time, a band 2 of a water-swellable composition is placed along the edge of the pine 1, and the band 2 is made of water-swellable composition. The body 2 is sandwiched between the mats 1 and 1.
該帯体２を構成する水膨潤性組成物としては、

を用いて作成したものなどが考えられる。 The water-swellable composition constituting the band 2 includes:
Compositions based on water-swellable polymeric substances such as swellable polyurethane resins or swellable polyvinyl, modified products of polyethylene oxide, styrene-maleic anhydride copolymers, cross-linked polyvinylpyrrolidone products, acrylic acid-acrylic Possible examples include cross-linked amide copolymers, hydrolysates of starch-acrylonitrile copolymers, and polymers made from cellulose derivatives.
そして、かかる膨潤性物質を主材としてこれに
液状ゴムその他のゴム材をコンパウンドしたも
の、若しくは熱可塑性エラストマー等比較的ゴム

する。 Suitable materials include compounds made of such a swellable substance as a main material and compounded with liquid rubber or other rubber materials, or compounds made of a synthetic resin relatively similar to rubber such as thermoplastic elastomer.
なお、施工手順としては、下方になるアスフア
ルトマツト１を先に敷設し、次いでその縁に沿つ
て少し奥に帯体２を並べていき、最後に上方にな
るアスフアルトマツト１の端を重ね合わせる。 As for the construction procedure, the lower asphalt pine 1 is laid first, then the strips 2 are arranged a little deeper along its edge, and finally the ends of the upper asphalt pine 1 are overlapped.
このようにしてマツト１の接合部を形成した場

後も安定した物性を維持できる。 When the joint of the mat 1 is formed in this way, the band 2 is made of swellable polyurethane. Water is incorporated into the urethane molecular structure as hydrogen bonds, and the entire body swells. Since the vertical direction of the band 1 is held down by the mat 1, it spreads laterally as shown by the dotted line a, and a wide seal is obtained.Also, as water is taken in as described above, a stable water stop is achieved. It is effective and maintains stable physical properties even after swelling.

As described above, the asphalt pine joining method of the present invention uses a joint medium when overlapping the ends of the asphalt pine to form a joint, but this medium and the pine are joined by rolling pressure using rollers. It is easy to install as it does not require any work or adhesive application, and provides an effective water-stopping structure with a large adhesion margin.
