Description
Technical field
The utility model is used for technical field of bridge construction, particularly relates to a kind of arch bridge needle beam, stringer and bridge deck cast-in-place construction travelling bridge.
Background technology
Along with development, the growth in the living standard of China's economic strength, arch bridge is applied in town road more and more as a kind of bridge type attractive in appearance.For half-through steel box tied arch bridge, " Y type " triangle frame structure and upper steel case is often had to encircle above main pier even in aggregates.This structure construction order is generally: 2 " Y type " triangle frame concrete on main pier bearing platform of first constructing, then 2 edge-beams above constructing, " Y type " structure is made to become triangular structure, the large-scale transverse beam (before, during and after point) of constructing again between two triangular structures, finally construction 2 edge-beams and 3 large-scale transverse beams surround needle beam, stringer and the bridge deck in the middle of profile, form complete spanning load-carrying members.Be positioned at edge-beam and three large-scale before, during and after monolithic reinforced concrete structure between crossbeam be called needle beam, stringer and bridge deck.For needle beam, stringer and bridge deck cast-in-place construction in half-through steel box tied arch bridge triangle frame structure, according to design feature and on-site actual situations, the construction method of economical rationality can be selected.
Under normal circumstances, needle beam, stringer and bridge deck cast-in-place construction conventional method are: beam-column holder method is cast-in-place, raft support method is cast-in-place.
1. beam-column holder method: inserted to play steel pipe pile or prefabricated tubular pile basis below cast-in-place concrete structure, to construct little cushion cap, steel pipe post and connection structure are installed, pile cover and capital distribution beam, arrange that Bailey beam and bracing frame are formed as leap beam type braced structures and build support, Bailey beam end face arranges little distribution beam and steel pipe scaffold, its end face is adjusted to various pouring structure shape as required, last formwork erection, assembling reinforcement concreting, is beam-column holder method cast-in-place.
2. raft support method: the ground below cast-in-place concrete structure is carried out changing fill out, cure process, set up bowl fastening type or fastener type steel pipe scaffold, its end face is adjusted to various pouring structure shape as required, jacking and Tuo Nei distribution beam are installed, then formwork erection, assembling reinforcement concreting, is raft support method cast-in-place.
The shortcoming of prior art:
1. cast-in-place for beam-column holder method, can in land or use waterborne, need at each across inserted to play steel pipe pile below concrete structure or prefabricated tubular pile basis, make little cushion cap, need the steel pipe pile or prefabricated tubular pile, reinforcing bar and the concrete that consume some, this portion of material reclaims difficult or value is low, and particularly in-water foundation recovery difficult is very large.Need more heavy mechanical equipment: land piling needs pile driver, and marine piling needs pile driving barge, the peaces processed such as the steel pipe post in beam-column holder method and support need loop wheel machine, and waterborne needs hangs ship.Steel pipe support is heavier, and dismounting falls to use not easily.
2. cast-in-place for raft support method, use on land only, dismounting is fallen with more convenient than steel pipe support method, and main equipment uses less, but requires that bearing capacity of foundation soil is higher.Often need to change ground and fill out, build place hardened concrete, if at weak fault place or use raft support method waterborne, basement process cost is very high.
3. beam-column holder method and raft support method all need repeatedly to fall to use, the mounting or dismounting such as steel pipe and support need to use loop wheel machine, hang the crane gears such as ship, and full framing mounting or dismounting need more artificial unloading, also need loop wheel machine with the use of, two kinds of method convenience for construction are limited.
4. beam-column holder and full framing all need hole-specifically to install, and hole-specifically carry out load precompressed, and workload is large, and labour cost is large, dangerous, uneconomical.
5. the mounting or dismounting of beam-column holder and full framing all belong to work high above the ground, and security risk is large, and because support needs repeatedly to pacify to tear open, security risk is long, terminate from support installing construction to support removing construction always.
