[0001] The invention relates to the field of single-cabin pipe gallery production, and in particular to prefabricated single-cabin pipe gallery production equipment. Background Art

[0002] During the production process of the prefabricated single-cabin pipe gallery, the steel cage is hoisted into the mold equipment, concrete is poured, and then demoulding is performed to form the pipe sections of the pipe gallery.

[0003] Since the tunnel is a pipe structure, its mold equipment has inner and outer templates, which form a U-shape. During demolding, both the outer and inner templates need to be separated from the formed concrete components. The outer template is demolded by moving toward the outside of the mold. There is a wide space outside the mold, and its mold opening is not restricted. However, the inner membrane plate needs to be moved toward the middle of the mold for demolding, and its space is limited. The traditional mold opening structure cannot be used to achieve mold opening operations. Summary of the invention

[0052] After the mold is closed, the steel cage is placed into the cavity by lifting equipment.

[0053] Then pour the concrete in the cavity. After the concrete pouring and the upper surface of the pipe section is smoothed, it should be covered with plastic film in time and then steam cured.

[0054] After curing and cooling, the mold is opened and the pipe section is taken out; the mold opening operation is specifically as follows: by loosening the clamping nut 10064, the limit with the fixed seat 10063 is cancelled, and the flip screw 10061 is rotated to make the flip screw 10061 leave the notch on the fixed seat 10063, and the tension of the outer template 1001 is cancelled, and then the outer template 1001 is moved, and the slide seat 1005 slides on the slide rail 1003 to make the four outer templates 1001 away from the pipe section, so as to realize the opening of the outer mold, and then the second positive and negative wire pull rod 1008 is contracted to fold and flip the second movable plate 10022 to separate from the pipe section, and then the first positive and negative wire pull rod 1007 is contracted to separate the first movable plate 10021 from the pipe section, and the opening of the inner mold is completed.

[0055] After the mold is opened, the pipe section is hoisted and transported away.
