Abstract
The utility model discloses a drainage ditch with large gradient, which comprises a ditch bottom (1), ditch walls (2), a set of water drop stages (3) and water retaining stages (4). The ditch walls (2) are arranged on two sides of the ditch bottom (1), the water drop stages (3) are disposed along water flow direction and have heights successively reduced, the water retaining stages (4) are mounted at the edges of the water drop stages (3). By arranging the set of the water drop stages with unequal gaps in the ditch, the water drop stages with successively reduced heights can successively slow water flow, and relieve scouring force of water to the ditch bottom. Additionally, the water retaining stages disposed at the edges of water drop stages are capable of preventing silts and sundries from being scoured to the tail end of the drainage ditch by the water flow. Therefore, the drainage ditch is capable of reducing areas of an absorption basin and a sedimentation basin arranged at the tail end of the drainage ditch, saving occupied land and lowering drainage cost.
Description
Technical field
The utility model relates to a kind of gutter, particularly relates to a kind of heavy grade gutter.
Background technology
In the design in heavy grade gutter,, the drop platform is set in the gutter through regular meeting in order to alleviate the scouring force of water to bottom of trench.The end face of existing drop platform (no matter single-stage or multistage) generally all is the plane, if carried under one's arms silt or foreign material in the gutter, current can all be flushed to the gutter end to these silts or foreign material, therefore need build a very big absorption basin and sedimentation basin at the end in gutter, absorption basin and sedimentation basin need take very big land area and draining cost.
The utility model content
The purpose of this utility model is, a kind of heavy grade gutter is provided, it can well alleviate the scouring force of water to bottom of trench, and can prevent that current are flushed to the gutter end with silt or foreign material, therefore can reduce to be located at the absorption basin and the sedimentation basin area of gutter end, save the area, reduce the draining cost.
The technical solution of the utility model: a kind of heavy grade gutter, its formation comprises bottom of trench, the bottom of trench both sides are provided with furrow bank; Bottom of trench is provided with the drop platform that one group of height reduces step by step, and the edge of drop platform is provided with the dash platform.
In the above-mentioned heavy grade gutter, described drop platform is step-like, and drop platform two ends are connected with furrow bank.
In the aforesaid heavy grade gutter, the spacing between described one group of drop platform equates or does not wait.
In the aforesaid heavy grade gutter, the height of described dash platform is concordant with furrow bank, and is higher than drop platform at the corresponding levels plane, and is lower than the higher level platform plane of dropping.
Compared with prior art, the utility model is provided with the drop platform that one group of spacing does not wait in the ditch, and the drop platform of Jiang Diing can slow down water velocity step by step highly step by step, alleviates the scouring force of water to bottom of trench.Be provided with the dash platform on drop edge of table edge in addition, the dash platform can prevent that current are flushed to the gutter end with silt or foreign material, therefore can reduce to be located at the absorption basin and the sedimentation basin area of gutter end, saves the area, and reduces the draining cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the lateral view of Fig. 1.
Being labeled as in the accompanying drawing: 1-bottom of trench, 2-furrow bank, the 3-platform that drops, 4-dash platform.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment.A kind of heavy grade gutter, its structure as shown in Figure 1, the arrow among Fig. 1 is represented water (flow) direction.Fig. 2 is the lateral plan of Fig. 1.During concrete enforcement, first ditching body, ditch body comprise bottom of trench 1 and are located at furrow bank 2 compositions of bottom of trench 1 both sides; At bottom of trench 1 Parallel to the flow direction the drop platform 3 that one group of height reduces step by step is set, drop platform 3 is step-like, and drop platform 3 two ends are connected with furrow bank 2.Drop platform 3 is as stair, the reduction of one-level one-level height or raise height, and Parallel to the flow direction is to reduce height, but the spacing between each grade drop platform 3 equates or does not wait.Edge at drop platform 3 is provided with dash platform 4, the height of dash platform 4 is concordant with furrow bank 2, current can be flushed to the outside, gutter with unprecipitated silt or foreign material like this, can prevent from silt or foreign material all are flushed to the gutter end, to alleviate the treating capacity of terminal silt in gutter or foreign material, can reduce to be located at the absorption basin and the sedimentation basin area of gutter end, save the area, reduce the draining cost.Smooth for current, the dash platform 4 at each grade drop platform 3 edges is higher than drop platform at the corresponding levels 3 planes, and is lower than higher level platform 3 planes of dropping.
Claims (4)
1. heavy grade gutter, its formation comprises bottom of trench (1), bottom of trench (1) both sides are provided with furrow bank (2); It is characterized in that: bottom of trench (1) Parallel to the flow direction is provided with the drop platform (3) that one group of height reduces step by step, and the edge of drop platform (3) is provided with dash platform (4).
2. heavy grade according to claim 1 gutter is characterized in that: described drop platform (3) is for step-like, and drop platform (3) two ends are connected with furrow bank (2).
