HAND HOLE JOINT STRUCTURE AND CONSTRUCTION METHOD THEREOF
PROBLEM TO BE SOLVED: To provide a hand hole joint structure and a construction method thereof which is easy to construct, makes it possible to reduce a construction period, and excels in finish after construction.SOLUTION: The hand hole joint structure includes a connection tube 2 and a protective tube 3. The connection tube 2 is inserted from the inner circumference side of the peripheral wall 1 of the hand hole into an insertion hole H provided in the peripheral wall 1 of the hand hole, with an engagement part 6 stretching out to the outer circumference side included at the end on the inner circumference side of the peripheral wall 1 of the hand hole of the connection tube 2 and a buffer member 4 fitted on the outer circumference of the tube held between it and the peripheral wall 1 of the hand hole of the connection tube 2, the buffer member 4 blocking a gap between the insertion hole H into which the connection tube 2 is inserted and the peripheral wall 1 of the hand hole. The protective tube 3 is inserted inside the connection tube 2 and in contact with a reception part 7 provided in the inner circumference of the connection tube 2, the outer circumferences of the protective tube 3 and connection tube 2 being covered with a cover material 5 that blocks a clearance in a place where the protective tube 3 and the connection tube 2 are connected.SELECTED DRAWING: Figure 1
【課題】 本発明は、施工が簡単で工期を短縮できるとともに、施工後の仕上がりも良好なハンドホールの継手構造と、その施工方法を提供することにある。【解決手段】 ハンドホールの継手構造であって、接続管２と、防護管３とを備えており、接続管２は、ハンドホールの周壁１に設けてある挿通孔Ｈに、ハンドホールの周壁１内周側から挿通するものであり、接続管２のハンドホールの周壁１内周側の端縁には、外周側に張り出した係止部６を有しており、接続管２の管外周部には、ハンドホールの周壁１との間に挟まる緩衝部材４が嵌合してあり、緩衝部材４は、接続管２が挿通孔Ｈに挿通したときのハンドホールの周壁１との間を閉塞し、防護管３は、接続管２の管内に通すとともに、接続管２の管内周部に設けてある受け部７に当接しており、防護管３と接続管２の管外周部には、防護管３と接続管２の接続箇所の隙間を閉塞するカバー材５を被覆していることを特徴とする。【選択図】 図１
