Embodiment Construction

[0017] Such as Figure 1-3 As shown, the lifting slope track connection device of the present invention comprises wedge-shaped flat steel track 3, channel steel and 5 door-shaped steel plates 6, and the door-shaped steel plate is placed on the TBM supporting standard rail 1 on both sides, and two wedge-shaped flat steel tracks 3 are symmetrically arranged on On the door-shaped steel plate 6, two channel steels 5 are arranged on the outer side of the TBM single-line standard rail to be welded with the door-shaped steel plate, and four limit bolts 4 are fixed at the front and rear of the channel steel.

[0018] The wedge-shaped flat steel track is 70*50mm flat steel (16Mn), the door-shaped connecting steel plate is 10mmQ235 steel plate, the channel steel is [10, and the limit bolt is M22*60 high-strength bolt.

[0019] The processing of this track connection device: process steel materials such as wedge-shaped Mn16 flat steel, door-shaped connecting steel plate and [10 channel s...

Abstract

The invention discloses a lifting slope rail connecting device which comprises wedge-shaped flat steel rails, channel steel and n-shaped steel plates.The n-shaped steel plates are arranged on TBM matched standard rails on the two sides.The two wedge-shaped flat steel rails are symmetrically arranged on the n-shaped steel plates, the two pieces of channel steel are arranged on the outer sides of two TBM single-line standard rails and welded to the n-shaped steel plates, and four limiting bolts are arranged in front of and behind the channel steel for limiting and fixing.An internal combustion marshalling locomotive can safely provide vertical transition lap joint for two single-line rails through an inverted arch trolley so that the situation that rail jumping accidents frequently happen to the internal combustion marshalling locomotive within the lifting slope section rail joint range can be avoided.

Description

technical field [0001] The invention belongs to the technical field of water conservancy and hydropower civil engineering, and in particular relates to an ascending and descending slope track connection device during synchronous construction of full-face hard rock boring machine tunnel excavation and inverted arch concrete. Background technique [0002] In the bottom invert of the open TBM tunnel, the inverted arch double-channel synchronous lining formwork trolley is used to replace the prefabricated solution with cast-in-place concrete, which solves the space and traffic interference between TBM tunnel construction excavation and inverted arch concrete pouring, and makes the inverted arch concrete pour Simultaneous construction with TBM excavation produces better social and economic benefits. The scheme of invert trolley cast-in-place has been widely used in the tunnel construction of Liaoning East-West Water Diversion Project, and it is expected to continue to be populari...
