Abstract
The utility model discloses a kind of absorption basin energy-dissipating structure, owing to being provided with the baffle wall style that bank height is the pond body degree of depth 1 ~ 1.2 times at the leading portion of body inside, pond, during the initial earial drainage in lock hole, lock hole concentrates down the current let out to enter Chi Tihou, stopped by baffle wall style at the front-end position of pond body, by baffle wall style gate local opened to let out at present to be adjusted to the hydraulic jump that far becomes in the body of pond and force hydraulic jump, thus add the energy dissipation rate of absorption basin; Meanwhile, by baffle wall style effect and the bank current crossed crossing baffle wall style form secondary at pond body back segment and fall, its energy dissipation again, thus improve effect of energy dissipation; In addition, by baffle wall style, original concentrating can be adjusted to the even overcurrent of Kan Ding into pond current, increase the area of passage entering pond body back segment, can significantly reduce earial drainage erosion damage.The utility model arranges the high baffle wall style for the pond body degree of depth 1 ~ 1.2 times of bank by the leading portion of body inside, pond can improve effect of energy dissipation, and need not lengthen apron segment length, and the structure of baffle wall style is simple, easy construction.
Description
Technical field
The utility model relates to a kind of energy-dissipating structure, particularly a kind of absorption basin energy-dissipating structure.
Background technology
Riverbed, plains region mostly is alluvium, and impact resistance is poor, and low water head engineering enters the riverbed in downstream again after the form of absorption basin disspation through hydraudic jimp usually can be adopted to carry out energy dissipating to the current let out under upstream.
When the initial earial drainage in lock hole, because water levels of upstream and downstream difference is large, lock hole goes out in adfluxion, enter pond current Fr number (i.e. froude number, it represents that gravity convection moves the accurate number of impact) lower, earial drainage forms repelled downstream hydraulic jump in absorption basin, directly go out absorption basin, secondary down stream is produced in apron section, apron section is caused to destroy, and the design size of absorption basin meets the demands when calculating, for solving this problem, forefathers or to lay quantity in absorption basin more, form of structure is complicated, the baffle pier that difficulty of construction is large, or it is dark to increase pond, pond is long, or increase apron segment length, improve level of protection, so both uneconomical also inconvenient.
Summary of the invention
The purpose of this utility model is to provide a kind of absorption basin energy-dissipating structure, and its effect of energy dissipation is good, structure is simple, easy construction and need not lengthen apron segment length.
A kind of absorption basin energy-dissipating structure described in the utility model, its pond body is positioned between the gate of upstream and the apron in downstream, and the leading portion of body inside, pond arranges horizontal baffle wall style, and the bank height H of this baffle wall style is 1 ~ 1.2 times of pond body degree of depth h.
Absorption basin energy-dissipating structure described in the utility model, owing to being provided with the baffle wall style that bank height is the pond body degree of depth 1 ~ 1.2 times at the leading portion of body inside, pond, during the initial earial drainage in lock hole, the current let out are concentrated down in lock hole, enter Chi Tihou, stopped by baffle wall style at the front-end position of pond body, by baffle wall style gate local opened to let out at present to be adjusted to the hydraulic jump that far becomes in the body of pond and force hydraulic jump, thus add the energy dissipation rate of absorption basin; Meanwhile, by baffle wall style effect and the bank current crossed crossing baffle wall style form secondary at pond body back segment and fall, its energy dissipation again, thus improve effect of energy dissipation; In addition, by baffle wall style, original concentrating can be adjusted to the even overcurrent of Kan Ding into pond current, increase the area of passage entering pond body back segment, can significantly reduce earial drainage erosion damage.Obviously, the utility model arranges the high baffle wall style for the pond body degree of depth 1 ~ 1.2 times of bank by the leading portion of body inside, pond can improve effect of energy dissipation, and need not lengthen apron segment length, and the structure of baffle wall style is simple, easy construction.
Accompanying drawing explanation
Fig. 1 is top view of the present utility model.
Fig. 2 is the sectional view of Fig. 1 along A-A direction.
Detailed description of the invention
As shown in Figure 1 and Figure 2, described absorption basin energy-dissipating structure, comprise pond body 1, pond body 1 is between the gate 2 and the apron 3 in downstream of upstream, the leading portion of pond body 1 inside arranges horizontal baffle wall style 4, the bank height H of this baffle wall style 4 is 1 ~ 1.2 times (degree of depth h of pond body 1 is the degree of depth bottom body tail bank 13 top to pond body 1, pond) of pond body degree of depth h, and its two ends can be connected with the waterwall 11,12 of pond body 1 both sides.During the initial earial drainage in lock hole, the current let out are concentrated down in lock hole, after entering pond body 1, are stopped by baffle wall style 4 at the front-end position of pond body 1, by baffle wall style 4 gate local opened to let out at present to be adjusted to the hydraulic jump that far becomes in pond body 1 and force hydraulic jump, thus add the energy dissipation rate of absorption basin; , to act on by baffle wall style 4 and the bank current crossed crossing baffle wall style 4 form secondary at pond body 1 back segment and fall, its energy dissipation again meanwhile, thus improve effect of energy dissipation; In addition, by baffle wall style 4, original concentrating can be adjusted to the even overcurrent of Kan Ding into pond current, increase the area of passage entering pond body 1 back segment, can significantly reduce earial drainage erosion damage.
Described baffle wall style 4 is 1 of pond body length L with the distance D of body front end, pond
/3 ~ 1
/when 2, such as D can be 0.35L, 0. 4L, 0.45L, 0.5L etc., and as D=0.45L, its effect of energy dissipation is better.
Claims (3)
1. an absorption basin energy-dissipating structure, its pond body is positioned between the gate of upstream and the apron in downstream, it is characterized in that: the leading portion of body inside, pond arranges horizontal baffle wall style, and the bank height H of this baffle wall style is 1 ~ 1.2 times of pond body degree of depth h.
2. absorption basin energy-dissipating structure according to claim 1, is characterized in that: the distance D of described baffle wall style and body front end, pond is 1 of pond body length L
