Embodiment Construction

[0031] Such as figure 1 Among them, an annular prestressed steel strand threading trolley includes a platform 1, at least one set of first reversing pulleys 3 and second reversing pulleys 3' are arranged on both sides of the upper part of the platform 1, and the lower part of the platform 1 At least one winch 5 is provided on one side, and a pressure roller device 7 is correspondingly provided on the other side of the lower part of the stand 1 . Wherein, the pressure roller device 7 is used for initially utilizing the frictional force between the roller and the single steel strand 8 and the hardness and flexibility of the single steel strand 8 itself to penetrate the single steel strand 8 into the corrugated Inside the tube 11.

[0032] In an optimized solution, a space for passage is provided in the middle of the platform 1 . The platform 1 adopts a "gate"-shaped structure through the middle, so that the middle of the tunnel can pass through during the cable threading proce...

Abstract

An annular prestressed stranded wire reeving trolley comprises a rack, wherein at least one group of a first reversing pulley and a second reversing pulley are arranged at two sides of the upper part of the rack, at least one winch is arranged at one side of the lower part of the rack, and a pressure rotary drum device is correspondingly arranged at the other side of the lower part of the rack. According to the invention, the pressure rotary drum device is matched with the winch to carry out reeving, and the annular prestressed stranded wire reeving trolley and the reeving method have the following beneficial effects: 1, steps are simple, the convenience is brought for the operation, and the construction speed is high; 2, mechanical operation is mainly adopted in the invention, so that the efficiency is improved, and the labor intensity of workers is relieved; 3, the convenience is brought for the machining and maintenance of the trolley; 4, in the reeving process, the traffic inside a tunnel is smooth, other construction steps are not affected, and the construction period is saved; and 5, steel strands can be stored in the trolley, so the capability and efficiency of in-tunnel horizontal transportation are improved. The invention also discloses the reeving method.

Description

technical field [0001] The invention relates to the construction field of prestressed tunnels, in particular to an annular prestressed steel strand threading trolley and a cable threading method. Background technique [0002] With the continuous development of prestressed tunnel construction technology, large-scale long-distance water conveyance tunnels have gradually started construction. The existing technology lacks the construction experience of the prestressed inner lining of large-scale water diversion tunnels. The construction process of the cable is mostly carried out manually, which has low work efficiency and cannot meet the requirements of modern ring prestressed construction. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an annular prestressed steel strand threading trolley and a cable threading method, which can realize fast cable threading in the construction of an annular prestressed tunnel, and ...
