Embodiment Construction
[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0023] like Figure 1-2 As shown, a prefabricated component of a large-scale pipe and box includes the internal structural steel bars of the pipe and the box and the external pouring concrete. The inner diameter side walls of the pipe and the box are symmetrically distributed with two pin pipes 3 relative to the axis, and The plug tube 3 is set at the midpoint of the length of the tube and box, and the end of the plug tube 3 connected to the inner wall of the tube and box is fixed with a square plate 31, which is welded with the internal structural steel bars of the tube and box and buried in the p...

The invention belongs to the technical field of butting of prefabricated parts of large pipes and boxes, and particularly relates to the prefabricated parts of the large pipes and boxes and a planar precise butting method thereof. Traction mechanisms are symmetrically distributed on opposite axes on the inner diameter side walls of the prefabricated parts, the traction mechanisms comprise inserting and connecting seats which are fixedly connected with the inner walls of the pipes and the inner walls of the boxes, inserting pieces connected with the inserting and connecting seats in an inserted mode and pulling cables arranged in the end portions of the inserting pieces in a penetrating mode, and at least one inserting and connecting seat is arranged at the middle point of the length of the pipes and the boxes. According to the prefabricated parts, the operation of two chain blocks in the pipes and the boxes is carried out through one person so that errors and interference generated by multi-person control can be avoided, the operation is simple and safe, and the accurate butting of the plane positions of the pipes and the boxes can be achieved efficiently.
Description
technical field [0001] The invention belongs to the technical field of butt jointing of prefabricated components of large pipes and boxes, and in particular relates to a prefabricated component of large pipes and boxes and a plane precise butt joint method thereof. Background technique [0002] In recent years, with the rapid growth of my country's national economy, domestic infrastructure construction has developed rapidly, especially the construction of underground pipe corridors and sponge cities. The hoisting and docking of box prefabricated parts is a relatively common construction content. The operation method in the prior art is exactly to keep the pipes and boxes in place still, and lift another section of pipes and boxes with a truck crane. Under the operation of several people, the lifted pipes and boxes are Pull and adjust repeatedly to achieve precise docking with the tubes and boxes already in place. However, the docking method in the prior art not only require...
