Description
Technical field
The utility model belongs to a kind of nonopiate anti-structure of drainning off floodwaters for next door area solar energy optical-thermal place.
Background technique
As the continuous mature and accumulation of solar energy techniques and national policy are helped, the demonstration item of photo-thermal power generation
Mesh starts to rise.Major part demonstrative project is built on the Gobi desert of the preferably western flood plain of light resources supplIes at present, photo-thermal
Place range is wide and landform is comparatively smooth.But photo-thermal place is more demanding to geological conditions, especially slot type photo-thermal power generation
Thermal-collecting tube in system is especially sensitive to uneven settlement of foundation, if flood enter place easily cause bracket ground wash away or under
Heavy, stress concentration easily occurs for thermal-collecting tube junction, causes security risk.Therefore slot type photo-thermal place do not allow over-the-counter flood into
Enter, flood is generally led to by downstream using Cut-off ditch, flood is avoided to enter photo-thermal place.
Current flood control way and there are the problem of it is as follows.
1, Gobi desert Flood Characteristics: Gobi Desert, Northwest of China beach is rushed to piedmont belt farther out and is formed under flood effect
The flood plain of large area.In the Northwest 7, August part flood season, flood has what is formed to last short, sudden strong, oncoming force act of violence
Suddenly, destructive big feature, and Gobi desert stratum is more single, is vertically distributed relatively stable, is mainly made of circle gravel, in circle
A small amount of Extra-fine sand is accompanied locally with the filling of gravelly sand, thick, middle sand and a small amount of cohesive soil with Asia circle, erosion resistibility is weak,
Flood temporarily easily causes soil erosion.
2, current flood control measure there are the problem of: because photo-thermal place range is larger, every edge lengths reach several kilometers, when photo-thermal field
After area arranges Cut-off ditch, the flood discharge channel of the original coombe of Gobi desert will be changed, because Cut-off ditch is lower than original coombe, if cutting flood
Ditch does not build shield or only simple arrangement Cut-off ditch, and in heavy rain, upstream flood carries silt and gravel channel can be right
Upstream gully erosion is serious, is also easy to produce the phenomenon that advance of ditch head, gully bed downcutting and ditch bank are expanded;It also results in tidal channel and becomes silted up simultaneously
Product is serious, causes anti-flood discharge facility impeded drainage, seriously affects the safety of photo-thermal place.
Utility model content
The technical issues of the utility model is solved is providing a kind of the nonopiate of Gobi Region solar energy optical-thermal place
Anti- structure of drainning off floodwaters.
Technological means used by the utility model is as described below.
A kind of nonopiate anti-structure of drainning off floodwaters of Gobi Region solar energy optical-thermal place, photo-thermal place is with upstream gully direction
It is nonopiate, overfall is set in photo-thermal place periphery upstream, diversion trench is set outside overfall, the gully of photo-thermal place upstream with should
Diversion trench handover is drained off floodwaters.
The overfall and diversion trench with photo-thermal place peripheral parallel.
The diversion trench extends to both ends respectively, joins with the primitive groove gully of photo-thermal place two sides.
The outside setting stone masonry of the overfall and sandy gravel stratum protection.
The overfall end of the every side in photo-thermal place at least extends 10m with respect to photo-thermal place.
The overfall height is higher by 500mm, windbreak of 3 slope foot of overfall apart from photo-thermal place avris than water level
At least 1m.
It is had the beneficial effect that caused by the utility model.
The utility model proposes the anti-structure of drainning off floodwaters of photo-thermal place and gully when nonopiate, i.e., set gear in place peripheral hardware simultaneously
Mill weir and guiding gutter, the more traditional Cut-off ditch stability of the structure is high, and the service life is long, at low cost, while not being contained by flow rate of water flow, channel
Mud amount, channel width, groove channel erosion type etc. influence, and runoff and silt will be let out under effective guide coombe to other coombe, is guaranteed
The purpose of place safe flood.
The overfall of the utility model is mainly used to that upstream gully charge for remittance is prevented to enter place, while preventing place two sides certainly
Right gully migrates, the bases such as impact place windbreak.Guiding gutter is used to that charge for remittance is guided to drain into downstream along overfall outside.
Detailed description of the invention
Fig. 1 is the distribution schematic top plan view in photo-thermal place and periphery gully and anti-structure of drainning off floodwaters in the utility model.
Fig. 2 is the enlarged structure schematic diagram in Fig. 1 circle.
Fig. 3 is the M-M sectional schematic diagram in Fig. 2.
Specific embodiment
The utility model protects a kind of nonopiate anti-structure of drainning off floodwaters of Gobi Region solar energy optical-thermal place.
Embodiment as shown in Figure 1 is photo-thermal place gully distribution schematic diagram, and topography is that the high south in north is low.The east of photo-thermal place 1,
Western two sides are provided with primitive groove gully, and interior water (flow) direction is by north orientation south, i.e. the north of photo-thermal place 1 is updrift side, and the south is
Downstream direction.The direction of photo-thermal place 1 is nonopiate with inflow direction.And the direction of photo-thermal electric field is and due south, north, east, west
There is certain rotation.Diagram is illustrated so that photo-thermal place and gully are in 45 ° as an example.
Guiding gutter 2 is set simultaneously and the combined mode of overfall 3 protects photo-thermal place 1.
Overfall 3 is arranged in parallel along photo-thermal place windbreak upstream outer, diversion trench 2 is arranged in parallel outside overfall 3,
Updrift side in photo-thermal place 1 has several gullies, and gully and diversion trench 2 join.Diversion trench 2 respectively to photo-thermal place both ends
Extend, joins until with the primitive groove gully of 1 two sides of photo-thermal place.Above-mentioned overfall 3 is mainly used to that upstream gully charge for remittance is prevented to enter
Place, guiding gutter 2 are used to that charge for remittance is guided to drain into downstream on the outside of overfall 3.
The step of overfall is arranged in practice of construction is as follows.
1, it determines weir height: design flood level being determined according to the flood control standard of place, overfall height is higher than design flood level
500mm out.
2, basic setting-out: in place, surrounding determines overfall position, and general overfall slope foot is outside windbreak 1m.
3, it excavates foundation trench: excavating overfall foundation trench and guiding gutter, the topsoil of cleaning surface 200mm or so.
4, it fills weir body: using foundation trench spoil compaction in layers to designed elevation, using stone masonry and gravel on the outside of place
Bed course protection.Overfall height is substantially parallel with place natural grade, the weir body end place Xu Kuanchu 10m or so, to prevent charge for remittance
Migration.
