[0037] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.
[0038] The invention relates to the improvement of the concrete pouring of the starting base of the shield machine, so as to solve many problems existing in the arc surface pouring of the current starting base of the shield machine. The present invention innovatively proposes a concrete pouring device for the starting base of the shield machine. The formwork body, arc-shaped top beam and multiple top plates arranged on the basis of the side plates can form a circular-arc surface at the top for pouring. When pouring, it is only necessary to install the formwork body and the arc-shaped top beam, and then pour concrete while installing the top plate, which can effectively ensure the quality of concrete pouring on the arc surface.
[0039] see Figure 1-3 As shown, a concrete pouring device for the starting base of the shield machine is shown, wh...
