Abstract
The utility model discloses a culvert with an energy dissipation function. More than two roughening blocks (2), in concrete structures, used for decreasing the water flow velocity are arranged on a base plate of a culvert body (1) in rows along the water flowing direction, and the roughening blocks (2) and the base plate of the culvert body (1) are connected through steel bars (3) integrally. According to the culvert, the roughening block structures are arranged on the base plate of the drainage culvert body, energy dissipation can be performed on the water flow passing the drainage culvert body effectively, the water flow velocity is decreased, the culvert concrete grade can be lowered, the stilling pool size can be reduced or even the stilling pool can be omitted, the outlet anti-scour facility investment can be reduced, and the culvert is highly adaptive to being one arranged on a steep slope or being one with narrow outlet terrain and has broad application prospect.
Description
Technical field
The utility model relates to a kind of culvert with dissipating functions, belongs to Hydraulic and Hydro-Power Engineering technical field.
Background technology
In Hydraulic and Hydro-Power Engineering, erosion and torrent control works and highway construction, conventionally because the gradient is steep, its flow rate of water flow is larger while arranging discharge culvert, impact-resisting wear-resisting to culvert is had relatively high expectations, due to high-velocity flow washing away culvert, can cause the destruction of culvert structure, the general high grade impact-resisting wear-resisting concrete that adopts, as culvert structure concrete, can make increase of investment like this; For reaching the object of energy dissipation below spillway, at culvert outlet operated by rotary motion absorption basin or erosion control facility, in the area of narrow terrain, owing to arranging that the condition of absorption basin or erosion control facility is poor, for arranging that absorption basin need to excavate in a large number, cause investment too high in addition; In addition, the erosion control facility investment of outlet also can increase greatly because flow rate of water flow becomes.
Utility model content
The purpose of this utility model is to provide a kind of culvert with dissipating functions, can effectively reduce high-velocity flow washing away culvert.
For realizing the purpose of this utility model, the utility model adopts such technical scheme: the culvert with dissipating functions of the present utility model, be on the base plate of culvert along water (flow) direction set in a row more than two for slow down flow rate of water flow concrete structure add rough block, add rough block and culvert baseplate reinforcing bar is connected to form integral body by connecting reinforcement, make culvert itself there is energy dissipating effect, thereby overcome the deficiencies in the prior art.
As a kind of preferred version, add preferably rectangle of rough block section, adding rough block section can be also the shape except rectangle, as triangle, rhombus and other is irregularly shaped etc.
Further, add rough block arranges perpendicular to water (flow) direction projection on the base plate of culvert.Add rough block and also can protrusion direction and water (flow) direction on culvert base plate be more than 60 ° angle, need to guarantee to add the slow down effect of rough block to flow rate of water flow.
Further, add the integral body that rough block is preferably connected with culvert wall, every row adds rough block and is a monoblock and laterally culvert base plate is blocked.But add the gapped independent part that rough block is not also connected with culvert wall, add rough block at the every row of culvert base plate a plurality of independent parts that are horizontally arranged at interval.
The beneficial effects of the utility model are:
Compared with prior art, the utility model is by adding the structure of rough block in the setting of discharge culvert base plate, can effectively to the current through discharge culvert, carry out energy dissipating, reduce flow rate of water flow, can reduce culvert concrete grade, reduce absorption basin size and even cancel absorption basin, lower outlet erosion control facility investment, to being arranged in the culvert of discharge culvert on abrupt slope, outlet narrow terrain, have good compliance, the culvert that this kind has dissipating functions has broad application prospects.
accompanying drawing explanation
Fig. 1 is that the utility model adds rough block at the layout schematic diagram of culvert bottom;
Fig. 2 is the A-A sectional view in Fig. 1;
Fig. 3 be of the present utility model add rough block in culvert with the layout inclination angle schematic diagram of water (flow) direction.
Description of reference numerals: 1-culvert, 2-adds rough block, 3-connecting reinforcement.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, Figure 2, a kind of culvert structure with dissipating functions described in the utility model, comprises the culvert 1 of reinforced concrete structure and is arranged at adding rough block 2 on culvert base plate, adds rough block 2 and is connected by connecting reinforcement 3 with the reinforcing bar of culvert 1 base plate.The section configuration of culvert 1 of the present utility model is for being rectangle or trapezoidal or gateway opening shape etc.During construction, can select other form of fracture according to actual condition, take and reach good effect as object.
Adding rough block 2 arranges and can also can have certain angle with water (flow) direction by Transverse to the flow direction, as shown in Figure 3, α is the angle that adds rough block protrusion direction and water (flow) direction, for guaranteeing to add the energy dissipating effect of rough block, this angle can be 90 °, can be also other angle, as 80 °, 70 °, but this angle should not be less than 60 °.
The section configuration that adds rough block 2 can be other shapes of thinking except rectangle.The actual conditions that can follow up during construction are selected, and take and reach good effect as object.
As shown in Figure 1 and Figure 2, the utility model, when construction, mainly carries out in accordance with the following steps:
The first step, the axial location of first definite culvert 1, after determining the axial location of culvert 1, excavation or backfill form culvert 1 basis;
Second step, determine add rough block 2 cross dimensions and with the arrangement form such as current angle.
The 3rd step, colligation connecting reinforcement 3 and fixed form, culvert 1 baseplate reinforcing bar and colligation together with reinforcing bar in adding rough block 2, to form whole
The 4th step, builds culvert 1 and adds rough block 2, according to general concrete construction method, builds.
Certainly, be more than concrete exemplary applications of the present utility model, the utility model also has other embodiment, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, within all dropping on the desired protection domain of the utility model.
