Description
Technical field
The utility model relates to a kind of large-scale deep type water inlet air vent arrangement, belongs to the hydraulic structure field in Hydraulic and Hydro-Power Engineering.
Background technology
In Hydraulic and Hydro-Power Engineering, along with storehouse large in reservoir, the quickening of dark storehouse pace of construction, large-scale water delivery (diversion), outlet structure escape works get more and more, its water inlet is independently arranged in bank mostly, free-standing large-scale deep type water inlet is caused to occur more and more, conventional air vent arrangement form is lock chamber section intermediate arrangement rectangle air vent after gate, vent size width is large, cause breastwork span before and after air vent large, in addition before and after air vent, suffered by breastwork, water pressure is large, for meeting structural safety needs, usually need the enlarged in thickness of breastwork before and after air vent, and strengthen configuration reinforcement amount, after before and after air vent, breastwork gauge strengthens, and then cause whole intake tower size to lengthen, increase water inlet tower body concrete structure engineering amount and reinforcing bar amount, increase water inlet basis and slope rock mass excavation supporting engineering quantity, and then add construction cost, reduce construction speed.
Summary of the invention
For solving the problem, the utility model provides a kind of large-scale deep type water inlet air vent arrangement.This air vent arrangement reduces the span of the forward and backward barricade of air vent, and reduce its gauge, and then reduce the overall dimensions of whole water inlet, decrease concrete and amount of reinforcement, minimizing water inlet basis and slope ground body excavate and support engineering amount, reduce construction investment and shorten the engineering time.
The utility model is achieved by following technical solution.
A kind of large-scale deep type water inlet air vent arrangement, barricade and barricade after being arranged at the air vent after air vent before air vent before comprising air vent and being arranged at air vent, before described air vent, after barricade and air vent, barricade two ends arrange gate pier respectively, are also provided with support partition wall in described air vent before air vent after barricade and air vent between wall.
Before described air vent, barricade upstream side is provided with gate, and the gate slot of barricade and the interior setting of gate pier before being close to air vent during closing gate.
Described gate is positioned at water inlet lock chamber section.
Cat ladder is provided with in described air vent.
Before described air vent, after barricade and air vent, barricade and gate pier are Integral connection structure.
Described support partition wall is arranged in the middle of air vent.
The beneficial effects of the utility model are:
Compared with prior art, adopt water inlet air vent arrangement described in the utility model, reduce the span of the forward and backward barricade of air vent largely, the thickness of the forward and backward barricade of air vent can be reduced further after the span of the forward and backward barricade of air vent reduces, and then shorten the entire length of the intake towers such as water inlet gate pier, base plate, thus greatly reduce concrete and amount of reinforcement, decrease water inlet basis and slope ground body excavation and support engineering amount, effectively reduce construction investment, shorten the engineering time simultaneously.
Accompanying drawing explanation
Fig. 1 is structure vertical section of the present utility model schematic diagram;
Fig. 2 is the flat generalized section of structure of the present utility model.
In figure: barricade before 1-air vent, 2-air vent, 3-supports partition wall, barricade after 4-air vent, 5-cat ladder, 6-gate pier, 7-pressure water road, 8-gate, 9-water inlet lock chamber section.
Detailed description of the invention
The technical solution of the utility model is further described below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
As shown in Figure 1 and Figure 2, one described in the utility model large-scale deep type water inlet air vent arrangement, barricade 4 after barricade 1 and the air vent after being arranged at air vent 2 before comprising air vent 2 and the air vent before being arranged at air vent 2, before described air vent, after barricade 1 and air vent, barricade 4 two ends arrange gate pier 6 respectively, be also provided with and support partition wall 3 in described air vent 2 before air vent after barricade 1 and air vent between wall 4.In technical scheme, before air vent, after barricade 1 and air vent, barricade 4 forms air vent 2 jointly; Enough clearances are stopped between barricade 4 after barricade 1 and air vent before air vent.
Before described air vent, barricade 1 upstream side is provided with gate 8, and the gate slot of barricade 1 and the interior setting of gate pier 6 before being close to air vent when gate 8 is closed.To reach dash object, current are prevented to be with pressure flume 7; When pressure water road 7 water flowing runs, gate 8 must be opened.
Described gate 8 is positioned at water inlet lock chamber section 9.
For ease of entering maintenance pressure water road 7, in described air vent 2, be provided with cat ladder 5.
Before described air vent, after barricade 1 and air vent, barricade 4 and gate pier 6 are Integral connection structure.
Described support partition wall 3 is arranged in the middle of air vent 2.
As shown in Figure 1 and Figure 2, as long as the utility model is implemented in accordance with the following steps:
(1) according to the area of pressure water road 7 cross dimensions and overcurrent analytical calculation of flow rate determination air vent 2;
(2) tentatively draft the length of air vent 2 Parallel to the flow direction according to the area of water inlet lock chamber section 9 clear span and air vent 2, the length of air vent 2 Parallel to the flow direction drafted generally should not be less than 50cm, to enter people's demand during satisfied maintenance pressure water road 7;
(3) calculate according to being delivered to the load supporting partition wall 3 after water pressure suffered by barricade 4 after barricade before air vent 1 and air vent the thickness determining to support partition wall 3; Support partition wall 3 must need be arranged in the middle of air vent 2, both sides air vent 2 size symmetrical after being separated by it can be guaranteed like this, also reduce the span of barricade 4 after barricade 1 and air vent before air vent simultaneously to greatest extent;
(4) according to the length of cross sectional area correction air vent 2 Parallel to the flow direction of support partition wall 3;
(5) calculate respectively according to water pressure suffered by barricade 4 after barricade 1 before the width of air vent 2 and air vent and air vent and determine its thickness;
(6) before passing to air vent according to gate 8, the load of barricade 1 calculates and determines barricade 1 bottom enlarged size before air vent, should meet relative configurations demand simultaneously;
(7) guarantee that after barricade 1 and air vent, barricade 4 is Integral connection structure with gate pier 6 before air vent.
