Description
Technical field
The present invention relates to a kind of bridge pier protective devices.
Background technique
Local scour near pier (local scour near pier) refers to the obstruction due to bridge pier, and water flow is in bridge pier week
It encloses and is washed away caused by the strong vortex of generation.For ease of calculation, it is assumed that local scour near pier is after the completion of general scour
On the basis of carry out.Local scour is by factors such as streamflow regime, bridge pier pier shape, bed material composition, bed configurations.
It is directed to pier subsidence problem at present, those skilled in the relevant art's half takes following scheme: (1) increasing bridge pier bottom
Portion's width or diameter promote intensity, but so, bottom for a long time by current scour, can cause part by
It corrodes, bridge pier entirety unbalance stress is easy to produce crack, there is security risk.(2) stone or sandbag are accumulated in bridge pier surrounding,
Such case is feasible for the slow river of flow velocity, but river flow is faster, and water impact dynamics is bigger, it is easy to by four
The stone and sandbag in week wash away, and service efficiency is not high.
Summary of the invention
In view of the above-mentioned problems, the invention proposes a kind of bridge pier protective devices.
Specific technical solution is as follows:
A kind of bridge pier protective device, including bridge pier ontology；It is characterized in that, the bridge pier bodies top is provided with
Protection against erosion mechanism, bottom are provided with lower protection against erosion mechanism；
The upper protection against erosion mechanism includes screw type diversion trench and dismountable erosion control ring, the screw type water conservancy diversion
Slot is square groove, and in bridge pier bodies top surrounding, helically type is distributed from top to bottom；
The erosion control ring includes ring body, bottom abaculus, top flap and connecting plate, and the ring body is screw type knot
Structure, the ring body, bottom abaculus and top flap are an integral structure, and the bottom abaculus is strip, the bottom
Size, the shape of abaculus are corresponding with the screw type diversion trench, in use, the bottom abaculus is embedded in the screw type
Inside diversion trench；The top flap is obliquely installed in the ring body top outer；The ring body both ends are gone to upper and lower point
Cloth, the side at the ring body both ends are provided with screw-threaded counterbore, and the connection board ends are each provided with a tapped through hole, described
Tapped through hole is corresponding with the position of the screw-threaded counterbore；In use, connecting plate is located at the side at the ring body both ends, pass through
Bolt-through tapped through hole is fixed with screw-threaded counterbore, realizes that ring body both ends are fixed；
The lower protection against erosion mechanism includes bottom bracket, protective net, finger stone, ratchel and sandbag；The bottom branch
Frame quantity is 6, and the bottom bracket is uniformly distributed in the bridge pier body bottom portion surrounding, the bottom bracket and the bridge pier
Ontology is fixedly connected；Top and surrounding of the protection net in the bottom bracket, the protective net is by two adjacent bottoms
Between portion's bracket formed a protection against erosion cavity, the protection against erosion inside cavity be sequentially filled from top to bottom finger stone, sandbag with
And ratchel.
Further, the bottom bracket is right angled triangle plate body, rectangular plate body, square plate body and right angle ladder
One of shape plate body.
Further, the bottom bracket is right-angled trapezium plate body.
Further, the bottom bracket is structure wide at the top and narrow at the bottom, right-angle side side and the fixed company of the bridge pier ontology
It connects.
Further, the volume and quality of the ratchel are greater than the volume and quality of finger stone.
Further, the bottom bracket is high strength steel plate.
Further, anticorrosive water-proof coating is coated with outside the bottom bracket.
Further, the protective net is steel wire, and surface is coated with anticorrosive water-proof coating.
Further, the protective net is fixedly connected by welding with the bottom bracket junction.
Further, the connecting plate is square plate structure.
Compared with prior art, the invention has the benefit that
(1) protection against erosion mechanism uses the erosion control ring with top flap on, can carry out to river surface wave effectively anti-
It washes away, river surface wave is avoided to carry out beating impact to bridge pier ontology upper end；After top flap guides downwards wave, spiral
Type diversion trench also has guiding function to water flow, and water flow avoids directly impacting bridge pier ontology along diversion trench movement.Screw type is prevented
Ring design is rushed, can accomplish that vertical direction positions on bridge pier very well, water impact is avoided to cause erosion control ring to move up greatly very much, use
Reliably.
(2) protection against erosion mechanism uses protective net and bottom bracket under, forms multiple protection against erosion cavitys, avoids protection against erosion chamber
Intracorporal, stone and sandbag are lost, and the river degradation water that top moves downward water flow and bottom along diversion trench flows into
Enter protection against erosion cavity, by the setting layer by layer of protective net, ratchel, finger stone and sandbag, impulsive force is greatly reduced, to bridge
Pier ontology does not constitute injury, achievees the purpose that slow down and wash away.
