この種の継手部構造としては出願人が提案した実開平3−13349号公報がある 。該公報はマンホールの横穴と、該横穴に嵌挿する管渠端間の間隙閉塞用のゴム 輪であって、該ゴム輪は中心部に内、外方向に向けて無端輪状の切目を入れ、且 つ一定の間隔を置いた内外方向に前記の切目を通る締めボルトを挿通し、各締め ボルトの締め度合いにより前記ゴム輪を非締付け方向に大小において膨出するよ うにしたことを特徴とするマンホールと管渠間の継手部構造を記載している。 This type of joint structure is proposed by the applicant in Japanese Utility Model Application Publication No. 3-13349. . The publication describes a rubber for closing the gap between the side hole of a manhole and the end of a pipe that is inserted into the side hole. A ring, the rubber ring has an endless ring-shaped cut inward and outward in the center, and Insert the tightening bolts passing through the cuts in the inner and outer directions at regular intervals, and tighten each bolt. Depending on the degree of tightening of the bolt, the rubber ring may bulge in the non-tightening direction. This article describes the structure of the joint between a manhole and a pipe, which is characterized by the fact that

【考案が解決しようとする課題】[Problem that the idea aims to solve]

しかしながら提案した公報のゴム輪はマンホールの横穴に対する管渠の偏芯が 大きいと対応し得ないという課題があり、また施工後、地震、地盤沈下などにて 継手部分が不規則に高低したりする場合も対応しきれないという課題がある。 However, the proposed rubber ring in the publication does not have the eccentricity of the pipe with respect to the side hole of the manhole. If the size is large, there is a problem that it cannot be dealt with, and there is also the problem of earthquakes, ground subsidence, etc. after construction. There is also a problem in that it cannot cope with cases where the joint part is irregularly elevated or lowered.

【課題を解決するための手段】[Means to solve the problem]

本考案は継手用のゴム輪をマンホールの横穴の壁厚より幅広に形成して、その 内外両端部をやや部厚にして水膨脹性ゴムを組込んで、この両端部をそれぞれの 背面に嵌合する押圧用リングにて水膨脹性ゴムとともに横穴と挿入管渠の外面に 圧接するようにして、かかる課題を解決しようとするものである。 In this invention, the rubber ring for the joint is made wider than the wall thickness of the side hole of the manhole. By making the inner and outer ends slightly thicker and incorporating water-expandable rubber, these ends are A pressure ring that fits on the back side is used with water-expandable rubber to apply pressure to the outer surface of the side hole and insertion pipe. The present invention attempts to solve this problem by making pressure contact.

Form. One end 3a of the rubber ring 3 protrudes outward to provide an uneven wave surface 4, and a ring is provided in the middle. A water-expandable rubber 5 formed as a rubber ring is integrally fitted and brought into contact with the circumferential surface of the horizontal hole 2, A steel ring 6 as a pressing ring is fitted into a groove 7 provided on the inner surface of one end of the rubber ring 3. , due to the spreading action of the ring 6, the water-expandable rubber 5 and the unevenness are formed on the circumferential surface of the horizontal hole 2. Pressure is applied with the wave front 4 side crushed by about 30%.

【0007】 鋼材リング6は図3(b)に示すように有端リング形をして両端部は重なり合 っており、これを治具などにて引離してV形凹凸等に形成する端面6a,6bを噛合 わせて押し広げ作用をさせるのである。6c,6dは治具の掛孔である。[0007] The steel ring 6 has an end ring shape with both ends overlapping each other as shown in Fig. 3(b). These are separated using a jig, etc., and the end surfaces 6a and 6b are engaged to form a V-shaped unevenness, etc. It also works by pushing and spreading it. 6c and 6d are the hanging holes for the jig.

【0008】 管渠8はゴム輪3の他端3bに挿通して横穴2に挿入する。ゴム輪3の他端3bの 内面は厚板リング形状の水膨脹性ゴム9を一体に接続して且つ外面凹部10に嵌付 ける締付バンド11にて水膨脹性ゴム9を管渠8の外面に圧接させる。12は水膨脹 性ゴム9の内面に設けた小波面で締付バンド11の締付けにて3割方押潰された状 態で管渠8に圧接する。[0008] The pipe conduit 8 is inserted through the other end 3b of the rubber ring 3 and into the side hole 2. The other end 3b of the rubber ring 3 The inner surface is integrally connected with a thick ring-shaped water-expandable rubber 9 and fitted into the outer recess 10. The water-expandable rubber 9 is brought into pressure contact with the outer surface of the pipe 8 using a tightening band 11. 12 is water expansion The small wave surface provided on the inner surface of the elastic rubber 9 is crushed by 30% when the tightening band 11 is tightened. It is pressed against the pipe culvert 8 in this state.

【0009】 この水膨脹性ゴム9はゴム輪3に接続せずに、管渠8の外面に嵌着し、その外 面にゴム輪3の他端3bを重ねて締付けることもある。[0009] This water-expandable rubber 9 is not connected to the rubber ring 3, but is fitted onto the outer surface of the pipe conduit 8. The other end 3b of the rubber ring 3 may be placed on the surface and tightened.

【0010】 管渠8の横穴2内挿入と、水膨脹性ゴム9による締付けの完了後に、横穴2と 管渠8間の間隙13,14内をラテックス入りモルタル等にて内外方向から埋めて補 強し且つ液体の流通を円滑にするのである。0010 After inserting the pipe 8 into the side hole 2 and tightening it with the water-expandable rubber 9, the side hole 2 and Fill gaps 13 and 14 between pipes 8 from the inside and outside with latex-containing mortar, etc. It is strong and allows smooth flow of liquid.

【0011】 本考案ゴム輪はマンホールの横穴2に内端を取付けた状態で出荷して、管理お よび作業を簡便能率化する。[0011] The rubber ring of this invention is shipped with the inner end attached to the side hole 2 of the manhole for management and maintenance purposes. and make work easier and more efficient.

【考案の効果】[Effect of the idea]

本考案は以上のようにして、ゴム輪をマンホールの横穴の壁厚より幅広に形成 して、内,外の両端部にて横穴と管渠に圧接するようにしたから、横穴に対して 管渠の偏芯挿入を大幅に許容し、継手部分の地盤が地震等により高低してもゴム 輪の中間が弾力的に曲って対応して破損等を生じないという効果を生ずる。横穴 および管渠には水膨脹性ゴムを圧接するようにしたので、着水による膨脹によっ て水封止をさらに確実にするという効果を生ずる。 As described above, this invention forms a rubber ring wider than the wall thickness of the side hole of the manhole. Since the inner and outer ends are in pressure contact with the side hole and the pipe culvert, the inner and outer ends are pressed against the side hole. It allows eccentric insertion of pipes to a large extent, and even if the ground at the joint part is elevated or lowered due to earthquakes, etc., the rubber will remain stable. The middle part of the ring bends elastically, resulting in a corresponding effect that no breakage or the like occurs. side hole Water-expandable rubber is pressure-welded to the pipes and conduits, so that they do not expand due to water landing. This has the effect of further ensuring water sealing.
