CONCRETE PLACING APPARATUS OF TUNNEL CENTRE
To provide a concrete placing apparatus of tunnel centre for reducing a cost while eliminating a need for concrete supply branch piping.SOLUTION: A concrete placing apparatus of a tunnel centre includes concrete distribution mechanisms 3A to 3C that are disposed at a plurality of locations in the vertical direction along the inner peripheral surface of an arcuate frame body 11 of a tunnel centre 1 and distributes concretes supplied form a pump into a placing space S outside of the frame body 11 from the outer periphery surface of the frame body 11. The concrete distribution mechanisms 3A to 3C include a swivel tube 31, which is rotatably connected lower supply tube portions 41, 42, 43 of a concrete supply tube 4 and whose upper end opening can swivel around a lower end opening, and drive means 33 for moving the swivel tube 31 in a swivel motion. An upper end opening of the swivel tube 31 is connected to concrete placing tubes 2B, 2C, 2D connected to the placing space S at one position in a swivel direction, and the upper end opening of the swivel tube 31 is connected to upper supply tubes 42, 43, 44 of the concrete supply tube 4 at another position in the swivel direction.SELECTED DRAWING: Figure 1
【課題】コンクリート供給支管の配管を不要としつつコストの低減を図ったトンネルセントルのコンクリート打設装置を提供する。【解決手段】トンネルセントル１の円弧状枠体１１の内周面に沿って上下方向の複数カ所に配設されて、ポンプから供給されたコンクリートを枠体１１の外周面から枠体１１外の打設空間Ｓ内へ分配するコンクリート分配機構３Ａ～３Ｃを備え、コンクリート分配機構３Ａ～３Ｃは、コンクリート供給管４の下位の供給管部４１，４２，４３に回動可能に連結されて下端開口を中心に上端開口が旋回可能な旋回管３１と、当該旋回管３１を旋回移動させる駆動手段３３を備え、旋回方向の一位置で前記旋回管３１の上端開口が、打設空間Ｓへ連通するコンクリート打設管２Ｂ，２Ｃ，２Ｄに連通するとともに、旋回方向の他位置で旋回管３１の上端開口が、コンクリート供給管４の上位の供給管部４２，４３，４４に連通する。【選択図】 図１
