Description
Technical field
The utility model is related to bridge construction field more particularly to a kind of connection structures of the stake of bridge support and underwater binder
Technical background
Currently, in bridge construction and maintenance project work progress, the construction operation for bridge formation of paddling can be usually encountered, at this moment
In order to ensure the stability of bridge pier column, generally requires between two pier studs setting together or multiple tracks binder increases pier stud
Lateral stiffness, improve pier stud overall stability, binder section is mostly rectangular or rectangle.Traditional construction technique has installation underwater
The construction methods such as steel jacket box, steel cofferdam.Underwater steel jacket box is installed, steel cofferdam method is to install the good casing of pre-production, cofferdam
In place, draw water back cover, in the case assembling reinforcement, casting concrete, then removes steel jacket box, cofferdam.The method is in casting process
In, it is easy to be corroded by river water, the pouring quality of concrete is not easy to ensure；Working procedure is more, cumbersome；Casing, cofferdam week
Turn often, the duration of occupancy is long；The steel form and other equipment of input are more, and economy is relatively poor.
Invention content
In order to solve a series of problems caused by underwater steel jacket box, steel cofferdam method, the utility model provides a kind of bridge
The connection structure of corbel stake and underwater binder carries out pouring for bridge binder more than the water surface, overcomes of the existing technology
It is easy to be corroded by river water in casting process, the problem of pouring quality of concrete is not easy to ensure, construction method is simple, energy
The duration is saved, better economy.
The utility model solves technical solution used by its technical problem：A kind of company of the stake of bridge support and underwater binder
Binding structure includes：Left underwater binder, a left side block water box, outer casing, interior casing, pile foundation face, binder embedded bar, and the right side blocks water box, right
Underwater binder；There are one circular outer casings for the connection structure of a kind of bridge support stake and underwater binder；A left side for the outer casing,
Right both sides are connected separately with the left and right box that blocks water；Configured with casing in a circle inside the outer casing；The interior casing bottom to
It is upper to be configured with the bridge pile foundation embedded bar bound in advance；The bridge pile foundation embedded bar is higher by pile foundation face；Described
Interior casing and the left and right lifting of outer the casing underwater binder in a left side, right underwater binder configured with advance coagulation forming；The left underwater system
Beam, right underwater the mutual corresponding endface of binder is exposed respectively binder embedded bar；The underwater binder in the left side, right underwater system
Binder embedded bar on beam is interconnected and fixed with bridge pile foundation embedded bar.
The outer casing and the left box that blocks water, the right box that blocks water play the role of water proof, block water.
In use, the underwater binder in a left side of advance coagulation forming, right underwater binder are lifted into interior casing, outer casing respectively
Open-ended place keeps left underwater binder, the binder embedded bar on the right underwater mutual corresponding end face of binder and bridge pile foundation pre-
It buries reinforcing bar to intersect connection, be fixed；Then the formwork erection in interior casing pours left underwater binder, right underwater binder and bridge
The junction (variable cross-section) of beam pile foundation, then proceedes to the construction of top bridge.
The utility model has the beneficial effects that the connection structure of a kind of bridge support stake and underwater binder in the water surface with enterprising
Row bridge binder pours, and overcomes and is easy to be corroded by river water in casting process of the existing technology, concrete pours
Quality is not easy the problem of ensureing, construction method is simple, can save the duration, better economy.
Description of the drawings
The utility model is further illustrated with case study on implementation below in conjunction with the accompanying drawings.
Fig. 1 is the principle schematic diagram of the utility model.
In figure, 1. left underwater binders, 2. left sides block water box, 3. outer casings, casing in 4., 5. pile foundation faces, 6. binder pre-buried steels
Muscle, 7. right sides block water box, 8. right underwater binders.
Specific implementation mode
A kind of bridge support stake and the connection structure of underwater binder include：Left underwater binder 1, a left side block water box 2, outer casing
3, interior casing 4, pile foundation face 5, binder embedded bar 6, the right side blocks water box 7, right underwater binder 8；A kind of bridge support stake and underwater system
There are one circular outer casings 3 for the connection structure of beam；The arranged on left and right sides of the outer casing 3 is connected separately with block water box 2 and the right side
Block water box 7；3 inside of outer casing is configured with casing 4 in a circle；4 bottom of interior casing is upwards configured with binding in advance
Good bridge pile foundation embedded bar；The bridge pile foundation embedded bar is higher by pile foundation face 5；The interior casing 4 and outer casing 3
The underwater binder 1 in a left side of the left and right lifting configured with advance coagulation forming, right underwater binder 8；The left underwater binder 1, right underwater system
8 mutual corresponding endface of beam is exposed respectively binder embedded bar 6；On the underwater binder 1 in the left side, right underwater binder 8
Binder embedded bar 6 is interconnected and fixed with bridge pile foundation embedded bar.
The outer casing 3 and the left box 2 that blocks water, the right box 7 that blocks water play the role of water proof, block water.
Constructing tie beam technological process is：Outer casing 3 divides into → and left side box 2, the right side 7 installations of the box → cast-in-situ bored pile that blocks water that blocks water applies
Work → placement pile foundation embedded bar and interior 4 → underwater concreting of casing → pile crown cut and detect → interior casing 4, outer casing
Block water box 2, the right side of 3 progress U-shaped opening cuttings → left side blocks water the underwater binder 1 in 7 dismounting of box → left side, the right underwater transport of binder 8, placement
(binder prefabricated construction process is seen in synchronous construction part) → sealing drains interior casing 4, water → binder embedded bar 6 in outer casing 3
Installation binding → variable cross-section pours → and interior casing 4, outer casing 3 remove.
