The utility model discloses an anti-collision and anti-scouring variable-diameter combined pier column structure. Both the collision section and the pier section are columnar structures, the cross-sectional area of the anti-scouring section is larger than that of the anti-collision section, and the cross-sectional area of the anti-collision section is larger than the cross-sectional area of the pier section; The pier column structure can prevent the local erosion of the water flow on the surrounding of the bridge pier column and the impact of floating objects on the bridge pier column; There are three kinds of sections, and the positions of the variable sections are at the low water level and the flood level, which can effectively reduce the local erosion of the pier bottom and effectively protect against floating objects or ships at normal water levels.
Description
Technical field
The utility model belongs to bridge pier column structure field, is specifically related to a kind of crashproof protection against erosion reducing combined type pillarwork.
Background technology
As shown in Figure 1, the river crossing bridge pier stud of striding of the prior art mostly is the solid column structure of integral type that steel concrete consists of, the river crossing bridge pier stud of striding of this structure is the structure that block water, its existence not only makes current produce strong eddy current around pier column and causes local scour, and can make floating thing or boats and ships that bridge pier column is produced bump.The effect of impact of washing away with floating thing of current can cause the bearing capacity of pier stud to reduce or unstability, so that pier stud destroys or whole bridge collapses.
The utility model content
In view of this, the purpose of this utility model provides a kind of crashproof protection against erosion reducing combined type pillarwork, can not only effectively protect the local scour of current to producing around the bridge pier column, and can effectively reduce floating thing or boats and ships to the destructive power of bridge pier column collision, improve the safety and stability of bridge pier column.
The purpose of this utility model is achieved through the following technical solutions:
A kind of crashproof protection against erosion reducing combined type pillarwork, it is characterized in that: described pillarwork is from being followed successively by protection against erosion section, anti-collision section and bridge pier section to Dun Ding at the bottom of the pier, described protection against erosion section, anti-collision section and bridge pier section are column structure, described protection against erosion section section area is greater than the anti-collision section section area, and described anti-collision section section area is greater than bridge pier section section area;
Further, the length of described anti-collision section equals the flood level mark in river course and the difference between the low water line;
Further, the protection against erosion section of described pillarwork is provided with the spiral floor.
The beneficial effects of the utility model are: the utility model is made pier stud has reducing combined type pillarwork, can prevent that current are to the local scour around the bridge pier column and the floating thing bump to bridge pier column; This pillarwork is pushing up the descending three kinds of cross sections of making to pier at the bottom of with pier under the condition that satisfies bearing capacity and stability, the variable cross-section position is respectively at low water stage and flood level place, can effectively protect the bump of floating thing under the ordinary water level or boats and ships when can effectively reduce like this local scour at the bottom of the pier; Pillarwork surface below low water stage is made the spiral floor or is increased the roughness on surface, can change fluid in the position of pile surface burble point, weakens the intensity of eddy current and then prevents that effectively the current local scour from causing the pier stud unstability.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being apparent to those skilled in the art to investigating hereinafter, perhaps can from practice of the present utility model, be instructed.Target of the present utility model and other advantages can realize and obtain by following manual.
Description of drawings
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing the utility model is described in further detail, wherein:
Fig. 1 is pillarwork schematic diagram in the prior art;
Fig. 2 is structural representation of the present invention.
The specific embodiment
Hereinafter with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail.Should be appreciated that preferred embodiment only for the utility model is described, rather than in order to limit protection domain of the present utility model.
As shown in the figure, a kind of crashproof protection against erosion reducing combined type pillarwork, it is characterized in that: described pillarwork is from being followed successively by protection against erosion section 3, anti-collision section 2 and bridge pier section 1 to Dun Ding at the bottom of the pier, described protection against erosion section 3, anti-collision section 2 and bridge pier section 1 are column structure, described protection against erosion section 3 section area are greater than anti-collision section 2 section area, and described anti-collision section 2 section area are greater than bridge pier section 1 section area.
In the present embodiment, pier stud made have reducing combined type pillarwork, can prevent that current are to the local scour around the bridge pier column and the floating thing bump to bridge pier column; This pillarwork is pushing up the descending three kinds of cross sections of making to pier at the bottom of with pier under the condition that satisfies bearing capacity and stability, the variable cross-section position is respectively at low water stage and flood level place, can effectively protect the bump of floating thing under the ordinary water level or boats and ships when can effectively reduce like this local scour at the bottom of the pier.
In the present embodiment, the length of described anti-collision section equals 7 difference of flood level mark 5 and the low water line in river course; Just can make the anti-collision section of pillarwork low water line 5 and flood level mark 7 between when pier stud is installed this moment, namely be positioned on the segment of navigable water stage 6, can effectively protect the bump of floating thing under the ordinary water level or boats and ships when can effectively reduce like this local scour at the bottom of the pier.
In the present embodiment, the protection against erosion section of described pillarwork is provided with the spiral floor; Roughness being positioned at the pier stud protection against erosion section surface of low water line below 7 and making the spiral floor or increase the surface can change fluid in the position of pile surface burble point, weakens the intensity of eddy current and then prevents that effectively the current local scour from causing the pier stud unstability.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from aim and the scope of the technical program, it all should be encompassed in the middle of the claim scope of the present utility model.
