Specific embodiment
As shown in Figure 1, to be a kind of for improving the overall structure for pouring compactness device at the top of double-arched tunnel mid-board
Schematic diagram, including mid-board vault end head formwork 1, exhaust pipe 2, Grouting Pipe 3, tube bottom protective device 6 and PE ventilated membrane 7, it is described
Mid-board vault end head formwork 1 is arranged in mid-board vault both side ends, and the nozzle position of Grouting Pipe 3 is connected with slip casting machine 5, and
Link position carries out sealing treatment, and the nozzle position lower part of Grouting Pipe 3 is equipped with valve switch 4, guarantees inside entire Grouting Pipe 3
Leakproofness, the distal end of PE ventilated membrane 7 is fixed at the distal tip of mid-board vault, and mid-board vault end mould is stretched out in proximal end
Plate 1.
As shown in Fig. 2, being 1 schematic diagram of mid-board end head formwork of device described in the utility model, slip casting is offered above
