Abstract
The utility model provides a tower water inlet of bank, including setting up the water inlet tower body in diversion tunnel import department, bury the steel pipe for water conveyance who lets in in the diversion tunnel in the water inlet tower body underground, steel pipe for water conveyance's floor elevation is less than the stagnant water position and is higher than the sediment accumulation elevation, be equipped with in proper order from inside to outside in the water inlet tower body and overhaul gate slot and trash rack groove, the trash rack groove outside still is equipped with interim shutoff gate slot. The utility model discloses improved the preceding tower water inlet of bank type of construction of diversion tunnel import, the construction investment is saved in the influence of avoiding the operation period water inlet to receive the sediment accumulation, is an improved generation water inlet type of construction, is applicable to middle -size and small -size hydraulic and hydroelectric engineering.
Description
Technical field
This utility model belongs to Hydraulic and Hydro-Power Engineering field, is specifically related to a kind of be arranged in the bank tower intake before inlet of diversion tunnel.
Background technology
Diversion tunnel belongs to temporay building, and water conservancy diversion standard of flood is relatively low, and therefore inlet of diversion tunnel floor elevation is generally significantly less than Sediment Siltation elevation, and in this case, inlet of diversion tunnel place is easily subject to Sediment Siltation impact.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of bank tower intake, it is ensured that permanent runtime water inlet is not by the impact of Sediment Siltation.
This utility model solves technical problem and be the technical scheme is that a kind of bank tower intake, including the water inlet tower body being arranged on inlet of diversion tunnel place, burying the water conveyance steel tube passing in diversion tunnel in described water inlet tower body underground, the floor elevation of described water conveyance steel tube is lower than level of dead water and higher than Sediment Siltation elevation；Described water inlet tower body is sequentially provided with bulkhead gate groove and trash rack groove from inside to outside, outside described trash rack groove, is additionally provided with temporary plugging gate slot.
While adopting technique scheme, this utility model can also adopt or combine and adopt technical scheme further below:
Tamp with diversion tunnel occluding body between described water inlet tower body and described diversion tunnel.
Headstock gear framed bent is installed on the top of described water inlet tower body.
The side of described water inlet tower body is provided with and connects the access bridge of slope body above diversion tunnel.
Described bulkhead gate groove and described trash rack groove are additionally provided with the passage along water inlet tower body elevation direction before being laid in breastwork after described breastwork.
The beneficial effects of the utility model are: this utility model improves inlet of diversion tunnel foreland tower intake structural shape, runtime water inlet is avoided to be subject to the impact of Sediment Siltation, cost saving, is a kind of modified model water inlet structure pattern, it is adaptable to middle-size and small-size Hydraulic and Hydro-Power Engineering.
Accompanying drawing explanation
Fig. 1 is typical structure profile of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Detailed description of the invention
With reference to accompanying drawing.
A kind of bank tower intake of the present utility model, including the water inlet tower body 11 being arranged on diversion tunnel 7 import department, diversion tunnel occluding body 6 it is provided with between diversion tunnel 7 and water inlet tower body 11, diversion tunnel occluding body 6 plays the effect connecting diversion tunnel 7 and water inlet tower body 11, also acts as and tamps the effect that this segment space prevents from leaking.
The water conveyance steel tube 8 passed in diversion tunnel 7 is buried underground in water inlet tower body 11, the floor elevation of water conveyance steel tube 8 is lower than level of dead water and higher than Sediment Siltation elevation, water inlet tower body 11 is sequentially provided with bulkhead gate groove 3 and trash rack groove 1 from inside to outside, the direction near diversion tunnel 7 is referred in wherein, refer to outward the direction of diversion tunnel 7, described bulkhead gate groove 3 and described trash rack groove 1 are laid in breastwork 2 front, described breastwork 2 rear is additionally provided with the passage 5 along water inlet tower body 11 elevation direction, passage 5 is in the position near diversion tunnel 7, temporary plugging gate slot 10 it is additionally provided with outside trash rack groove 1, the width of temporary plugging gate slot 10 is more than the width of breastwork 2, its both sides are arranged in water inlet tower body 11.
Water inlet tower body 11 be arranged over headstock gear framed bent 4.
The side of water inlet tower body 11 upper end is provided with the access bridge 9 being connected to slope body above diversion tunnel 7.
In actual construction, before diversion tunnel 7 puts into operation, water inlet tower body 11 has been built at inlet of diversion tunnel place, water conveyance steel tube 8 is buried underground in water inlet tower body 11, simultaneously complete various gate slot structure, wherein water conveyance steel tube 8 floor elevation lower than level of dead water, higher than Sediment Siltation elevation, and should meet depth of immersion requirement.After water conservancy diversion terminates, temporary plugging gate 10 before closedown intake tower, carry out reconstruction of diversion tunnel, it is ensured that newly-built water-carriage system meets design function.
