Mud water balance shield tunnelling machine and pipe jacking tunnelling construction method by applying mud water balance shield tunnelling machine
The invention discloses a mud water balance shield tunnelling machine. The mud water balance shield tunnelling machine comprises a rotatable cutter disc and a cutting mechanism, wherein the cutter disc is provided with a conical surface with the cross section decreasing gradually and a propulsion surface, and the propulsion surface is provided with a material inlet; and the cutting mechanism comprises a first cutting component and a second cutting component, the first cutting component comprises cutters arranged on the cutter disc, the cutters comprise hobbing cutters and scraping cutters, thehobbing cutters comprise the first hobbing cutters distributed on the propulsion surface and the second hobbing cutters circularly distributed on the conical surface, the scraping cutters comprise the first scraping cutters distributed to the material inlet, the second scraping cutters distributed on the propulsion surface and the third scraping cutters circularly distributed on the conical surface, and the second cutting component comprises twist legs which support the cutter disc and rotate and a disc body which forms a crushing gap with the twist legs. According to the mud water balance shield tunnelling machine and a pipe jacking tunnelling construction method by applying the mud water balance shield tunnelling machine, crushed stone obtained by cutter crushing (primary crushing) canenter a crushing bin from the material inlet and further enter the crushing gap to be subjected to secondary crushing under mutual rotational shearing between the twist legs and the disc body.
本发明公开了泥水平衡盾构机，包括可转动的刀盘以及切削机构，所述刀盘具有横截面逐渐减小的锥面以及推进面，推进面上设有进料口；所述切削机构包括第一切削组件和第二切削组件；所述第一切削组件包括设于所述刀盘上的刀具，所述刀具包括滚刀和刮刀；所述滚刀包括分布于推进面上的第一滚刀和环形分布于锥面上的第二滚刀；所述刮刀包括分布于进料口的第一刮刀、分布于推进面上的第二刮刀以及环形分布于锥面上的第三刮刀；所述第二切削组件包括支撑所述刀盘并转动的扭腿以及与所述扭腿形成破碎间隙的盘体。经所述刀具破碎(一次破碎)得到的碎石可以从所述进料口进入破碎仓并进一步进入破碎间隙从而在扭腿和盘体的相互旋转剪切下被二次破碎。
