Detailed description of the invention
In order to there be understanding clearly to technical characteristic of the present utility model, object and effect, now contrast accompanying drawing and describe detailed description of the invention of the present utility model in detail.
Fig. 2 to Fig. 5 shows a kind of pier cap structure of the present utility model, and this pier cap structure structure is simple, saving material, when using in crossing river channel bridge, reduces depth rise, from the adverse effect to a certain degree reduced flood control.
Fig. 1 is schematic diagram when current walk around the lower edge of existing pier cap on facade.Fig. 2 is schematic diagram when current walk around the lower edge of the pier cap in the utility model on facade.Fig. 3 be pier cap structure in an embodiment of the present utility model face structural representation.Fig. 4 is the side-looking structural representation of the pier cap structure in an embodiment of the present utility model.Fig. 5 is the plan structure schematic diagram of the pier cap structure in an embodiment of the present utility model.
Consult Fig. 2 to Fig. 5, this pier cap structure comprises girder bent cap, bridge pier 2, pier cap 3 and pile foundation 4, and girder bent cap is arranged on bridge pier 2, and bridge pier 2 is arranged on pier cap 3, and pier cap 3 is arranged in pile foundation 4.
The long axis water (flow) direction of pier cap 3 is arranged, and on the facade of current, the lower edge of pier cap 3 is streamlined.The Main Function of this pier cap 3 is to reduce depth rise, generally, when current are through pier cap 3, current form three recirculating zones at cushion cap upstream face, bottom and back side when walking around pier cap lower edge, the local head loss of current through pier cap is numerically equal to because upper pond level heap soil or fertilizer over and around the roots is high, the extra head of the formation loss of three recirculating zones, thus increase upper pond level and stop up high.When pier cap 3 width and inlet flow conditions one timing, the shape of pier cap 3 lower edge determines the size of recirculating zone width.
Further, consult Fig. 5, this cross section along the length direction of bridge is that the structure of the pier cap 3 of ship type is specially: the side that meets water of pier cap 3 is provided with first and blocks water body 31, and the first laterally position placed in the middle evagination that to block water outside body 31 forms the first longitudinal ridge 32.The land side of pier cap 3 is provided with second and blocks water body 33, and the second laterally position placed in the middle evagination that to block water outside body 33 forms the second longitudinal ridge 34.And this first body 31 that blocks water effectively can also reduce floating thing on the water surface impact to pier cap 3 and bridge pier.This second body 33 that blocks water can also produce certain guide effect by the opposing connection current of crossing bridge pier, reduces the flow-disturbing that weak current produce around bridge pier.
