The overcurrent of the structure utilizes two stages of later period discharge channel overcurrent including the use of discharge channel overcurrent early period and after reconstructing.
In discharge channel overcurrent early period, discharge channel specific structure are as follows: including discharge channel early period, early period discharge channel medial side
Wall is connected with reconstruction joint section, reconstructs in joint section and is provided with detachable clay early period straw bag cofferdam.
It reconstructs joint section and discharge channel early period is divided into discharge channel Upstream section early period, discharge channel tract early period, the later period lets out
Water channel Upstream section and discharge channel early period Upstream section are common sections, when the later period reconstructs, discharge channel specific structure are as follows: under later period discharge channel
Trip section is connected to the downstream of reconstruction joint section；In early period, the upstream side of discharge channel tract is provided with detachable later period closure
Clay straw bag cofferdam, early period discharge channel tract the later period block clay straw bag cofferdam downstream side be provided with occluding body.
Preferably, there is bend, reconstruction joint section is connected to corner and is connected to bend inner wall in the middle part of discharge channel early period
For the side of spill.
For the construction method of above-mentioned discharge channel structure reconstruction, Specific construction step are as follows:
One, discharge channel early period and reconstruction joint section are built, reconstruction joint section is connected to the middle part of sliding channel of discharge channel early period, preceding
Before phase discharge channel overcurrent, heap has built clay straw bag cofferdam water retaining early period in reconstruction joint section, and water flow is from discharge channel overcurrent early period；
Two, during discharge channel early period overcurrent, later period discharge channel tract is built, and is coupled under reconstruction joint section
You Duan；Remove clay early period straw bag cofferdam, and early period discharge channel tract upstream side heap build the later period block clay straw bag enclose
Weir, water flow is by later period discharge channel overcurrent, in the case where the later period blocks the protection of clay straw bag cofferdam water retaining, blocks clay straw bag in the later period
Occluding body is built in the downstream side in cofferdam；Occluding body is complete build after, remove the later period block clay straw bag cofferdam, formed collection sand basin, build
It completes.
The beneficial effects of the utility model are: later period discharge channel tract is complete build after, i.e., dismountable clay early period straw bag encloses
Weir, in early period, the upstream side heap of discharge channel tract builds later period closure clay straw bag cofferdam water retaining, and water flow is let out by the later period at this time
Water channel overcurrent.Under the protection that the later period blocks clay straw bag cofferdam, the occluding body for later period water blocking is built.
Use early period clay straw bag cofferdam and the later period block clay straw bag cofferdam and have and be easy to heap and build, be suitable for water blocking and anti-
The characteristics of infiltration, while facilitating later period mechanical removal.
Occluding body is complete build after, remove the later period block clay straw bag cofferdam, later period discharge channel reconstruction complete.Joint section is reconstructed to connect
It is connected to corner and is connected to the side that bend inner wall is spill, can use Solution of Flow in Curved Channel feature as later period discharge channel
Collect sand basin, it is big using bend inner wall concave side flow velocity, bed load in water flow is shifted onto collection by transverse direction secondary circulations clockwise on bend
Inside sand basin, reduces bed load and mill is rushed to discharge channel.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and embodiments, and direction shown in arrow is water flow side in figure
To.
The overcurrent of discharge channel structure is let out with after reconstruction using the later period including the use of discharge channel overcurrent early period in the utility model
Two stages of water channel overcurrent.
As shown in Figure 1, in 1 overcurrent of discharge channel early period, discharge channel specific structure are as follows: including discharge channel early period 1, early period is let out
The middle part of sliding channel of water channel 1 is connected with reconstruction joint section 2, reconstructs in joint section 2 and is provided with detachable clay early period straw bag cofferdam
3。
When building the early period of discharge channel 1, while the reconstruction joint section 2 of certain length is built, reconstruction joint section 2
Length with can arrange clay straw bag early period cofferdam 3 for principle, and retain suitable length conveniently build later period discharge channel tract 5 with
Reconstruction joint section 2 connects.
As shown in Figures 2 to 7, discharge channel early period 1 is divided into discharge channel Upstream section early period 11, early period by reconstruction joint section 2
Discharge channel tract 12, later period discharge channel Upstream section 4 and discharge channel early period Upstream section 11 are common sections, after later period reconstruction, the later period
Discharge channel tract 5 is connected to the downstream of reconstruction joint section 2；Early period discharge channel tract 12 upstream side be provided with it is removable
Later period for removing blocks clay straw bag cofferdam 6, and early period, discharge channel tract 12 was set in the downstream side that the later period blocks clay straw bag cofferdam 6
It is equipped with occluding body 7.
Preferably, there is bend, reconstruction joint section 2 is connected to corner and is connected in bend in the middle part of discharge channel early period 1
Wall is the side of spill.It can use collection sand basin 8 of the Solution of Flow in Curved Channel feature as later period discharge channel in this way, it is recessed using bend inner wall
Effluent is fast greatly, transverse direction secondary circulations are shifted bed load in water flow inside collection sand basin 8 onto clockwise on bend, reduction bed load pair
Discharge channel rushes mill.
For the construction method of above-mentioned discharge channel structure reconstruction, Specific construction step are as follows:
One, as shown in Figure 1, building discharge channel early period 1 and reconstruction joint section 2, reconstruction joint section 2 is connected to discharge channel early period
1 middle part of sliding channel, early period discharge channel 1 before overcurrent, heap has built 3 water blocking of clay straw bag early period cofferdam, water flow in reconstruction joint section 2
From 1 overcurrent of discharge channel early period；
Two, as shown in Fig. 2, during 1 overcurrent of discharge channel early period, later period discharge channel tract 5 is built, and be coupled with changing
Build the downstream of joint section 2；As shown in figure 3, remove clay early period straw bag cofferdam 3, and early period discharge channel tract 12 it is upper
Trip side heap builds later period closure clay straw bag cofferdam 6, and water flow blocks clay straw bag cofferdam 6 by later period discharge channel overcurrent, in the later period
Under water blocking protection, occluding body 7 is built in the downstream side that the later period blocks clay straw bag cofferdam 6；It is built as shown in figure 4, occluding body 7 is complete
Afterwards, later period closure clay straw bag cofferdam 6 is removed, collection sand basin 8 is formed, builds completion.
