Description
Technical field
This utility model belongs to cable expansion technical field, especially relates to a kind of one-way expansion cable testing bridge.
Background technology
With economic fast development, the contact between offshore island and continent and between bay is more and more tightr, because
The birth of this bridge spanning the sea had not only solved the problems, such as that island powered, communicates, supplies water but also solves people-to-people contacts and cargo transport
Problem, is to achieve many things at one stroke.For laying the submarine cable of costliness, what bridge laid is all conventional cable, and
Cable laying in bridge, not only easy access but also be easy to safeguard, not only increase the operational reliability of cable, and have very high
Economy.But bridge is due to being affected by dynamic loadings such as temperature change, vehicle pass-through, wind, earthquakes, in the two ends meeting of bridge
Produce flexible and displacement.Because the cable in bridge case is all fixing, therefore such flexible and displacement can make cable excessively draw
Stretch, or even break cable, or excess compression, damage cable by pressure, so safe operation to cable just creates bad impact, because
This is necessary to take measures to eliminate this hidden danger.
Have multiple currently for the mode being used for adjusting cable length between bridge case, topmost mode has two kinds, a kind of
It is cable retractor device, another kind is chain type crane span structure, also have some other frame mode.But these mode generally existings some not
The place of foot.
1st, because the bridge packing list section length of present bridge is long, so requiring flexible amount between bridge case, also ratio is larger, such as
Although laid the requirement that can reach stroke using cable retractor device, cost costly, can not be extensive
Using.
2nd, the purpose being adjusted using the cable expansion that chain type crane span structure can also realize certain length, but the regulation of chain type crane span structure
Scope is very limited, and general regulated quantity is in 300mm, and regulated quantity between the bridge case of present bridge is all in 800mm,
The regulated quantity even having can reach 1700mm, thus chain type crane span structure cannot apply require in this range of accommodation very big over strait
On bridge.
3rd, it is directed to the specific position of some bridge casees of bridge spanning the sea, do not have special cable retractor device available.For example
In two neighboring bridge case, in one of bridge case, cable expansion crane span structure can be accommodated（I.e. bridge case I）, and another bridge case is subject to space
Limited and can not be accommodated cable expansion crane span structure（I.e. bridge case II）, just bring difficulty in this case the laying of cable expansion crane span structure
How topic, improve the difficult problem that cable expansion amount is even more in a difficult problem in this case.
Content of the invention
The purpose of this utility model is a kind of one-way expansion cable testing bridge, prevents cable easy quilt in bridge spanning the sea operation
Excessive compression and the problem broken, make cable running safety, reach the purpose of sustainable power supply.
The purpose of this utility model is realized by following technical proposals：
