Problems solved by technology

[0005] Provide a new type of concrete pier system to replace the steel pier system commonly used in suspended monorail transportation systems to solve the problem that the vehicle load carried is small, which is not conducive to earthquake resistance, and the track girder is prone to large deformation, which is not conducive to the linear control of the track girder and other issues; in addition, metal structures are also prone to corrosion, and durability is difficult to guarantee

Embodiment Construction

[0019] The present invention will be further explained in conjunction with the drawings:

[0020] Example A suspended monorail transportation concrete structure simply supported system adopts concrete piers, using concrete cap beam 1, pier column 2, pier foundation 3, supporting cushion 4, upper pendulum shear tenon on the support, and reserved concrete cap beam Channel 6-1a, concrete cover beam reserved channel 6-1b, base reserved channel 6-2, fixed support 7, cable 8, movable support 9, track beam 10, base 11 and support hem shear tenon 12.

[0021] Step 1 Prefabricated the track beam 10 with the pre-embedded base 11 in the workshop, and transported to the site to prepare the beam.

[0022] Step 2 In the on-site construction stage, pouring the main part of the concrete bridge pier system for suspended monorail transportation, including concrete cap beam 1, pier column 2, pier foundation 3, concrete cap beam reserved channel 6-1a, concrete cap beam reserved Channel 6-1b, and bury ...

Abstract

The invention relates to a concrete pier system for suspension type monorail traffic and a construction process applied to the suspension type monorail traffic. A suspension cable (8) penetrates into a concrete cover beam reserved duct (6-1a), a base reserved duct (6-2) and a concrete cover beam reserved duct (6-1b), so that a track beam (10) is suspended below a concrete cover beam (1), and the suspension cable (8), a bearing pad stone (4), support upper pendulum anti-shearing tenons (5) and a base (11) jointly form the concrete pier system for suspension type monorail traffic. According to the concrete pier system for suspension type monorail traffic and the construction process, the track beam is suspended below the concrete cover beam through a stay cable, so that suspension of the track beam is achieved, and the problems that a borne vehicle is small in load, vibration resistance is not facilitated, a track beam is prone to great deformation, linear control of the track beam is not facilitated, a metallic structure is prone to corrosion, and durance is difficult to guarantee are solved.

Description

Technical field [0001] The invention relates to a concrete bridge pier system and construction technology for suspended monorail transportation, which is applied to suspended monorail transportation. Background technique [0002] Worldwide, only a few places such as Dortmund and Dusseldorf in Germany, Chiba City and Kanagawa Prefecture in Japan have built suspended monorail lines with a certain mileage. The pier system in their civil engineering mainly uses steel pier systems. The steel track girder is simply supported on it by two metal supports on the steel bridge pier cover girder to form a steel bridge pier force system. This kind of steel bridge pier system carries a small vehicle load and is disadvantageous in anti-seismic. The track beam is prone to large deformation, which is not conducive to the linear control of the track beam. The metal structure is also prone to corrosion, which affects its durability. [0003] At present, the commonly used concrete piers at home and a...
