Especially today, with more and more intensive construction requirements, such a design has not been able to meet practical needs.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a furthest reduces land levying is provided, and the space between the diversion power generation system building of ingenious and reasonable utilization carries out the flood discharge drainage channel structure that the building of flood discharge arranged.
The utility model provides a technical scheme that its technical problem adopted is: flood discharge drainage channel structure includes at least one flood discharge groove to and along intake, factory building and the tailrace that rivers flow direction set gradually, the intake passes through the flood discharge groove and wears factory building section and tailrace intercommunication down, wherein, it sets up in the factory building below to wear the factory building section down.
Further, including setting up the diversion penstock between intake and the factory building, be parallel arrangement each other between flood discharge groove and the diversion penstock.
Further, the flood discharge groove is communicated with the water intake through the water inlet, and is communicated with the underpass plant section through the water outlet, wherein the position of the water inlet is higher than that of the water outlet.
Further, the bottom surface of the inner wall of the flood discharge groove is of a slope structure.
Furthermore, the water inlet of the water diversion penstock and the water inlet of the flood discharge groove are adjacently arranged.
Furthermore, the flood discharge grooves are all arranged in the same width along the water flow direction.
Further, the slope range of the bottom of the inner wall of the flood discharge groove is 15-25 degrees.
Furthermore, the water inlet of the flood discharge groove is of a closed structure.
Furthermore, the lower-penetrating workshop section is of a closed structure.
Furthermore, in the flood discharge groove, except the water inlet, the rest parts are all of open channel structures.
The utility model has the advantages that: when in actual use, the water flow at the water intake can flow to the tail canal through the flood discharge groove and the underpass plant section very conveniently and smoothly. Wherein, owing to wear the factory building section and set up in the factory building below, this space between this just make full use of diversion power generation system building to also need not again and arrange alone in the region outside diversion power generation system like traditional design, thereby reduced the permanent area of seeking land of engineering by a wide margin, reduced excavation supporting volume, very be favorable to the engineering intensification and reduce the engineering investment. The utility model discloses be particularly useful for among the small-size hydroelectric engineering diversion flood discharge system building layout design.
Drawings
Fig. 1 is a plan view of the present invention.
Fig. 2 is a cross-sectional view of the flood discharge trough mechanism of the present invention.
Labeled as: the water diversion and drainage device comprises a tailrace 1, a plant 2, a downward-penetrating plant section 21, a flood discharge groove 3, a water inlet 31, a water outlet 32, a water diversion pressure steel pipe 4 and a water intake 5.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
The flood discharge drainage channel structure shown in fig. 1 and 2 comprises at least one flood discharge groove 3, and a water intake 5, a plant 2 and a tailrace 1 which are sequentially arranged along the flow direction of water, wherein the water intake 5 is communicated with the tailrace 1 through the flood discharge groove 3 and a lower plant section 21, and the lower plant section 21 is arranged below the plant 2.
The traditional flood discharging hub is usually arranged in a region outside a water diversion power generation system independently, the flood discharging building and the water diversion power generation building are not interfered with each other due to the arrangement mode, and the space arrangement, the structural design and excavation supporting treatment are simple. However, the arrangement mode greatly increases the permanent land acquisition area of the project, increases the excavation supporting amount, is not beneficial to the intensive design of the project and is also not beneficial to reducing the investment. The utility model discloses to foretell defect, ingenious utilization the space between the diversion power generation system building carry out the flood discharge building and arrange, wherein, at first through flood discharge groove 3 and wear factory building section 21 and tailrace 1 intercommunication down, guarantee normal drainage needs. Secondly, underpass building section 21 is disposed below building 2, thereby making full use of the space below building 2. The improvement does not need to be independently arranged in regions outside the water diversion power generation system like the traditional design, thereby greatly reducing the permanent land acquisition area of the project and reducing the excavation supporting amount. In combination with practical experience, it is generally preferred that the flood discharge troughs 3 are all arranged with equal width in the direction of water flow.
For further optimization of the structural arrangement, the following options can be selected: the device comprises a water diversion penstock 4 arranged between a water intake 5 and a plant 2, and the flood discharge grooves 3 and the water diversion penstock 4 are arranged in parallel. As shown in fig. 2, such a structural arrangement makes the space occupied by the flood discharge trough 3 as small as possible, and meanwhile, when the flood discharge trough 3 is actually arranged, the interference with the water diversion penstock 4 is avoided, so that the whole arrangement space is more orderly.
In order to obtain more ideal drainage effect, the following scheme can be selected: the flood discharge groove 3 is communicated with the water intake 5 through a water inlet 31, the flood discharge groove 3 is communicated with the underpass plant section 21 through a water outlet 32, wherein the position of the water inlet 31 is higher than that of the water outlet 32. Preferably, the bottom surface of the inner wall of the flood discharge trough 3 can be selected to be a slope structure. For practical purposes, the slope of the bottom of the inner wall of the flood discharge trough 3 is preferably in the range of 15 ° to 25 °.
To optimize the layout, further exploiting the good space, such a scheme can be chosen: the water inlet of the water diversion penstock 4 is arranged adjacent to the water inlet 31 of the flood discharge trough 3. The scheme can further optimize the drainage effect, so that the drainage efficiency is improved.
In consideration of safety, noise control, and the like in flood discharge, such a scheme is preferable: the water inlet 31 of the flood discharge groove 3 is of a closed structure. At the same time, it is preferred that the underpass building section 21 is of closed construction, based on the same concept.
In addition, because the whole closing of the flood discharge groove 3 can increase the construction cost, besides the section of the sealing structure, the actual construction and use requirements can be met by selecting the rest parts of the flood discharge groove 3 as the open channel structure except the water inlet 31.
