MANHOLE
PROBLEM TO BE SOLVED: To provide a manhole capable of executing cleaning and repair work in the manhole having a spiral part.SOLUTION: A spiral flow system manhole having an outer cylinder part 5 and a spiral part 6 provided on the inside of this outer cylinder part 5, is provided with a ladder device 8 having a plurality of column members 24 in the center of the spiral part 6. The ladder device 8 is provided with an openable-closable landing place 31. Thus, an operator ascends-descends in the manhole 1 by using the ladder device 8 and can vertically move by opening the landing space 31, the landing place 31 is closed and used as a scaffold, and cleaning and repair work can be executed. A landing-water part 3 is also provided in an upper part of the manhole 1, and a plurality of inflow pipes 41 and 42 are connected to the landing-water part 3, and inflow water flowed in from the plurality of inflow pipes 41 and 42 is sent to the spiral part 6.SELECTED DRAWING: Figure 1
【課題】螺旋部を備えたマンホールにおいて清掃や補修作業を行うことができるマンホールを提供する。【解決手段】外筒部５と、この外筒部５の内部に設けた螺旋部６とを備えた螺旋流方式のマンホールにおいて、螺旋部６の中央に複数の柱部材２４を備えた梯子装置８を設ける。梯子装置８に、開閉式の踊り場３１を設ける。これにより梯子装置８を用いてマンホール１内を昇降し、踊り場３１を開いて上下に移動することができ、踊り場３１を閉めて足場として使用し、清掃や補修作業を行うことができる。また、マンホール１の上部に着水部３を設け、もの着水部３に複数の流入管４１，４２を接続し、複数の流入管４１，４２から流入した流入水が、螺旋部６に送られる。【選択図】図１
