Description

Safe bridge pier

Technical field

The utility model relates to building field, especially relates to a kind of safe bridge pier.

Background technology

Bridge pier comprises pier shaft and abutment body, pier shaft and abutment body be supporting bridge across agent structure, not only bear the whole load that bridge span structure transmits, but also directly bear the multiple loads such as soil pressure, water flow impact pressure, ice pressure, ship impact force, so pier shaft and abutment body all have enough intensity, rigidity and stability.

At present many for strengthening the stability of bridge pier and the device of rigidity, but its impact resistance and impact resistance can not take into account, ship knocks bridge pier conventionally, ship and bridge pier all can have very large damage, have increased maintenance cost; In the time of Flooding, the protective device of bridge is easily broken by hard thing, has reduced result of use; The water impact of the side of bridge pier is large, impacts for a long time bridge pier side, easily bridge pier stability is impacted; and the protective device of bridge adopts welding manner to install conventionally, and installing/dismounting difficulty, when maintenance; need to destroy whole protective device, maintenance cost is high.

Utility model content

The utility model, in order to overcome the deficiencies in the prior art, provides the shock resistance of a kind of side and collision performance good, maintenance safe bridge pier easily.

To achieve these goals, the utility model is by the following technical solutions: a kind of safe bridge pier, comprise bridge pier, bridge pier is along circumferentially comprising successively the semicircular wall that meets water, the first planar wall, semicircular backwater wall and the second planar wall, the outer cover of described bridge pier is provided with protective, forms protection gap between this protective and bridge pier; Protective comprises the front protection portion that meets water outside wall of being sheathed on, be located at the first planar wall and the second planar wall outside in the middle of protection section and be sheathed on the rear protection portion outside backwater wall, described front protection portion and rear protection portion and a middle protection section contact position are equipped with chimb, this chimb is fixedly connected with middle protection section by bolt, and middle protection section cross section is vertically waveform; Also comprise diversion body, diversion body comprises and is sheathed on the outer sleeve body outside front protection portion and is located at the fixed leg between front protection portion and outer sleeve body, and outer sleeve body is arranged with the protuberance of arc outward.

As preferably, described fixed leg is one, and fixed leg comprises the rear wall contacting with antetheca contact in the middle of outer sleeve body inwall with described front protection portion's outer wall centre.

In sum, the utlity model has following advantage: this setting, in the time having ship or other hard things to knock bridge pier, has reduced the damage of ship and bridge pier, has reduced maintenance cost, has increased safety; The in the situation that of Flooding; can avoid the hard thing coming with flood to destroy bridge pier; bridge pier side arranges corrugated middle protection section; this arranges the flow direction that has changed water; reduce the impact force of current to bridge pier side; can not impact the stability of bridge pier; and the protective device of bridge is installed by bolt; easy installation and removal, is conducive to maintenance, in the time that damaging appears in protective device; can change for the parts that damage; thereby reinforcement result of use, without whole protective device is changed, has saved cost.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

In order to make those skilled in the art person better understand the utility model scheme, below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out to clear, complete description.

As shown in Figure 1, a kind of safe bridge pier, comprises bridge pier 1, and bridge pier 1 is along circumferentially comprising successively semicircular wall 11, the first planar wall 13, semicircular backwater wall 12 and the second planar wall 14 of meeting water, the outer cover of described bridge pier 1 is provided with protective 2, forms protection gap between this protective 2 and bridge pier 1; This setting is in the time having ship or other hard things to knock bridge pier, can reduce the damage of ship and bridge pier, reduce maintenance cost, the in the situation that of Flooding, reduce to a great extent the damage of current to bridge pier, can avoid the hard thing coming with flood to destroy bridge pier, extend the application life of bridge pier, improved safety simultaneously.

Protective 2 comprises the front protection portion 21 that meets water outside wall 11 of being sheathed on, be located at the first planar wall 13 and the second planar wall 14 outsides in the middle of protection section 22 and be sheathed on the rear protection portion 23 outside backwater wall 12, described front protection portion 21 and rear protection portion 23 and middle protection section 22 contact positions are equipped with chimb, described chimb is fixedly connected with middle protection section 22 by bolt, and middle protection section 22 cross section is vertically waveform; Bridge pier side arranges corrugated middle protection section; this arranges the flow direction that has changed water, has reduced the impact force of current to bridge pier side, can not impact the stability of bridge pier; and the protective device of bridge is installed by bolt; easy installation and removal, is conducive to maintenance, in the time that damaging appears in protective device; can change for the parts that damage; thereby reinforcement result of use, without whole protective device is changed, has saved cost.
