Abstract
The utility model discloses a large-scale gate pier for water gate projects. The large-scale gate pier comprises a pier body, a gate pier head is arranged at one end of the pier body, a gate pier tail is arranged at the other end of the pier body, side walls on two sides of the gate pier tail adducted inwardly gradually and smoothly from the head end of the gate pier tail to the tail end thereof, and an arc-shaped side wall smoothly connecting the side walls on two sides of the gate pier tail is further arranged at the tail end of the same. Since the side walls adducted inwardly gradually and smoothly from the head end of the gate pier tail to the tail end thereof are arranged on two sides of the gate pier tail, when water flow passes, the water flow is diffused to enable the water flow passing a gate to have good water flow flowing state; and the side walls on two sides are connected by the arc-shaped side wall, strength of concrete at the position is guaranteed, and the large-scale gate pier is more stable in structure. The large-scale gate pier is applicable to various water gate projects.
Description
Technical field
The utility model relates to a kind of large gate Pier Project.
Background technology
Water gate engineering be build in the river course, channel or lake, Haikou, utilize gate control flow and regulate the hydraulic structure of water level, the application in hydraulic engineering is very extensive.During the sluice closed shutter, can flood retention, gear tide, retaining raise upper pond level, to satisfy the needs of upstream water intaking or navigation; During starting gate, can flood discharge, water drainage, sand surfing, water intaking or according to the needs adjust flux of downstream water.
Sluice is comprised of lock chamber, upstream linkage section and downstream linkage section.Lock chamber is the main body of sluice, is provided with base plate, gate, headstock gear, gate pier, breastwork, service bridge, access bridge etc.Gate is used for dash and control lock flow, and gate pier is in order to separate lock hole and supporting gate, breastwork, service bridge, access bridge etc.Base plate is the basis of lock chamber, to the ground transmission, has the weight of lock chamber superstructure and load concurrently the anti-effect that blends erosion control.Because the lockage flow shape is complicated, flow velocity is larger, and the configuration design of gate pier usually affects for the lockage flow-shape.At present for the design of gate pier, pier nose is generally taked semi-circular design owing to be the position that meets water, and for gate pier pier tail, generally adopts semi-circular, square and airflow design.
In the actual moving process of sluice gate, we usually find because its gate pier pier tail is designed to square or semi-circular, can not obtain good diffusion after causing current through the sluice gate lock chamber, current produce vortex in a big way behind pier, under the extruding of whirlpool, it is unstable to go out water seal stream, it is larger to fluctuate, flow-shape is comparatively unfavorable in the absorption basin, the increase of the local open degree of the intensity of whirlpool and strengthening, the bad fluidised form of this absorption basin is very big to the security implication of sluice self, because current are unstable, cause absorption basin base plate pressure fluctuation meter larger, cause the unstability of base plate.
In order to improve the flow-shape behind the gate pier pier tail, a kind of improved fairshaped pier tail pattern is suggested, through the model testing check, the pier tail of this pattern can effectively improve the flow-shape of absorption basin really, but through the Practical Project check, there are some shortcomings in this build, larger such as fairshaped tail point difficulty of construction, because the tail point is thinner on concrete structure, can not carry out arrangement of reinforcement again, under the impact of current, can cause damage, affect the normal operation of engineering.
The utility model content
The purpose of this utility model is to provide a kind of large gate Pier Project.
The solution that the utility model solves its technical problem is: a kind of large gate Pier Project, it comprises the pier body, one end of described pier body is provided with the gate pier pier nose, the other end of pier body is provided with gate pier pier tail, the sidewall on described gate pier pier tail both sides is received in the terminal round and smooth gradual change of gate pier pier tail from the head end of gate pier pier tail, and the end of gate pier pier tail also is provided with a curved wall with the round and smooth connection of sidewall on its both sides.
As further improvement in the technical proposal, the cross section of described curved wall is fan-shaped, and its radius is 1 ~ 2 meter.
As further improvement in the technical proposal, the cross section of described gate pier pier nose is semicircle.
As further improvement in the technical proposal, evenly be provided with several gate slots on the two side of described pier body, the gate slot of both sides is corresponding one by one, and gate slot all is arranged between gate pier pier nose and gate pier pier tail.
As further improvement in the technical proposal, the below of described pier body also is provided with the base plate that is fixedly connected with the pier body.
The beneficial effects of the utility model are: the sidewall of the utility model by receiving arrange from the head end of gate pier pier tail to the terminal round and smooth gradual change of gate pier pier tail on the both sides of gate pier pier tail in, so, when current through out-of-date, current obtain diffusion, make the current of lockage have good flow-shape, and by curved wall the both sides sidewall is connected, ensure the concrete intensity at this place, make its structure more stable.
The utility model is applicable to various water gate engineerings.
