Abstract
Prevent device of the bridge pier by current erosion the present invention relates to a kind of, including whirlpool plate and the retainer ring of disappearing, the Fixing shrink ring is located at bridge pier root, the retainer ring is fixed on by the connector of bridge pier lee side on bridge pier, said vortex reducing plate is fixedly connected in retainer ring, said vortex reducing plate is towards upper river, and the whirlpool plate that disappears is parallel with water (flow) direction, said vortex reducing plate and retainer ring bottom are located on the silt in riverbed, the prevention bridge pier is eliminated vortex system non-stationarity by the device of current erosion using the whirlpool plate that disappears, weaken vortex system intensity, fundamentally prevent bridge pier erosion attack, it is and simple in structure, it is easy for installation, it is at low cost.
Description
Technical field
The present invention relates to bridge safeguard more particularly to it is a kind of prevent bridge pier by current erosion device.
Background technology
Bridge pier is by current erosion attack, and all very prominent in the whole world, according to statistics, the U.S. 383 is risen in bridge collapse case, and 75%
It is related to bridge pier destruction；Department of scientific and Industrial Research of New Zealand repairs for bridge and accounts for its total funds 50% with the expense safeguarded,
Wherein bridge pier erosion repair expenses accounts for 70%；And the root that bridge pier erosion attack generates is unsteady for bridge pier root shape of a hoof vortex system
It washes away, takes away silt and bridge pier structure object；At present, China has become global first bridge construction with using big country, bridge pier erosion
Destruction problem is more acute, and maintaining demand is more urgent, and existing bridge pier is safeguarded mainly through bridge pier reinforcing etc. both at home and abroad
Measure carries out preventive maintenance, fails fundamentally to solve the problems, such as that bridge pier destroys, and it is of high cost, protection period is short.
The content of the invention
The applicant is directed to disadvantage mentioned above, has carried out Improvement, provides a kind of device of prevention bridge pier by current erosion.
The technical solution adopted in the present invention is as follows：
A kind of prevention bridge pier is by the device of current erosion, and including whirlpool plate and the retainer ring of disappearing, the Fixing shrink ring is located at bridge pier
Root, the retainer ring are fixed on by the connector of bridge pier lee side on bridge pier, and said vortex reducing plate is fixedly connected on retainer ring
On, said vortex reducing plate is towards upper river, and the whirlpool plate that disappears is parallel with water (flow) direction, and said vortex reducing plate and retainer ring bottom are located at river
On the silt of bed.
As being further improved for above-mentioned technical proposal：
The connector is setscrew, is fixed between the retainer ring and bridge pier at least through two setscrews.
Free end of the said vortex reducing plate away from retainer ring sets the tip for breaking current.
Beneficial effects of the present invention are as follows：It is described to prevent device of the bridge pier by current erosion, by retainer ring in bridge pier root
The whirlpool plate that disappears is fixed in portion, is eliminated vortex system non-stationarity using the whirlpool plate that disappears, is weakened vortex system intensity, fundamentally prevents bridge pier erosion and break
It is bad and simple in structure, it is easy for installation, it is at low cost.
Description of the drawings
Fig. 1 is top view of the prevention bridge pier provided by the invention by the device of current erosion.
Fig. 2 is side view of the prevention bridge pier provided by the invention by the device of current erosion.
In figure：1st, disappear whirlpool plate；11st, tip；2nd, retainer ring；3rd, bridge pier；4th, setscrew.
Specific embodiment
Below in conjunction with the accompanying drawings, the specific embodiment of the present invention is illustrated.
As shown in Figure 1 and Figure 2, the present embodiment prevention bridge pier by current erosion device, including whirlpool plate 1 and the retainer ring of disappearing
2, retainer ring 2 is set in 3 root of bridge pier, and retainer ring 2 is fixed on by two setscrews 4 of 3 lee side of bridge pier on bridge pier 3,
1 one end of whirlpool plate that disappears is fixedly connected in retainer ring 2, and towards upper river, free end sets and breaks current for 1 free end of whirlpool plate that disappears
Tip 11, and the whirlpool plate 1 that disappears is parallel with water (flow) direction, disappears whirlpool plate 1 and 2 bottom of retainer ring is located on the silt in riverbed.
When the prevention bridge pier is installed by the device of current erosion, 3 root of bridge pier is sleeved on by retainer ring 2, makes retainer ring 2
Bottom is located on the silt in riverbed, adjusts the direction of retainer ring 2, and the whirlpool plate 1 that disappears for making to connect in retainer ring 2 is directed toward on river
Trip, and it is parallel with water (flow) direction, behind the orientation for determining the whirlpool plate 1 that disappears, retainer ring 2 is tensed and is passed through in 3 lee side of bridge pier
Retainer ring 2 is fixed on bridge pier 3 by setscrew 4, you can and vortex system non-stationarity is eliminated by the whirlpool plate 1 that disappears, weakens vortex system intensity,
Fundamentally prevent bridge pier 3 by erosion attack.
Above description is explanation of the invention, is not the restriction to invention, limited range of the present invention is referring to right
It is required that in the case of the basic structure without prejudice to the present invention, the present invention can make any type of modification.
