Description
Technical field
The present invention relates to a kind of water-drawing channel structures, more particularly, to a kind of mountain area complex geological condition area flume
Road structure belongs to Design of The Hydraulic Structure building technology field.
Background technology
For precipitation water in be more than specified particle size harmful silt, make the silt content in water meet water quality requirement and with downstream canal
The sediment carrying capacity in road is adapted, and settling pit need to be created on water-drawing channel, plays the effect of sedimentation.But part power station work
Landform in the regional areas Cheng Xiujian is steep, and available place is limited, and by topographic and geologic conditionality, the water conservancy projects such as settling pit are built
Building object need to be built at hypsography low-lying.And the complicated geologic conditions at these hypsography low-lyings, even on slump, subsidence area or wet
Fall into area.If the area of these complex geologic conditions using conventional concrete desilting pool structure, just existence foundation depression it is excessive,
The risk that structure is easily destroyed.Therefore, adaptation to local conditions just becomes this field using reasonable, economic, practical desilting pool structure
Technical staff builds the technical issues of water-drawing channel must take into consideration under above-mentioned complex geological condition.
Invention content
The technical problem to be solved by the present invention is to：There is provided it is a kind of convenient for rapid construction, basement process is simple, low cost
Mountain area complex geological condition area water-drawing channel structure.
Used technical solution is to solve above-mentioned technical problem：A kind of mountain area complex geological condition area flume
Road structure, including it is arranged in the water-drawing channel ontology at low-lying topography, the water-drawing channel structure further includes settling pit, described
Settling pit be arranged in along water (flow) direction on the water-drawing channel ontology, projection and institute of the settling pit in its vertical section
It states projection of the low-lying topography in its vertical section to be adapted, the husky flow of folder into downstream water-drawing channel passes through the settling pit
The folder of precipitation removal ultra-specification is husky.
The beneficial effects of the invention are as follows：The application on the water-drawing channel ontology along water (flow) direction by being arranged one
The settling pit that projection on its vertical section is adapted with projection of the low-lying topography on its longitudinal section, and make to enter downstream diversion
The husky flow of folder of channel is husky by the folder of the settling pit precipitation removal ultra-specification.In this way, since the settling pit uses
Be the structure adaptable with projection of the low-lying topography on its longitudinal section, consequently facilitating rapid construction, and at ground
Reason is also relatively simple, and cost is also less expensive.
Further, the settling pit in the horizontal plane be projected as ellipse, the elliptical long axis draws with described
The longitudinal axis of water channel road ontology.
Further, the pool wall of the settling pit includes the bed course of lower part and the concrete ballast layer on top, described
The junction of bed course and the concrete ballast layer is provided with impervious barrier.
Further, the impervious barrier is anti-seepage geomembrane.
Further, there also is provided wearing layer on the upper surface of the concrete ballast layer.
Further, the wearing layer is high-strength abrasion-proof concrete layer.
Further, being provided with sand discharge outlet in the bottom that the desilting sinks.
Further, the sand discharge outlet is arranged in the bottom outside that the settling pit is located at upstream side.
Description of the drawings
Fig. 1 is the floor plan of mountain area complex geological condition of the present invention area water-drawing channel structure；
Fig. 2 is the A-A sectional views of Fig. 1；
Fig. 3 be this application involves to settling pit pool wall sectional view.
In figure label for：It is water-drawing channel ontology 1, settling pit 2, pool wall 3, bed course 4, concrete ballast layer 5, impervious barrier 6, resistance to
Grind layer 7, sand discharge outlet 8.
Specific implementation mode
Be as shown in Figure 1, Figure 2 and shown in Fig. 3 it is provided by the invention it is a kind of convenient for rapid construction, basement process is simple, cost
Cheap mountain area complex geological condition area water-drawing channel structure.The water-drawing channel structure includes being arranged in low-lying topography
The water-drawing channel ontology 1 at place, the water-drawing channel structure further include settling pit 2, and the settling pit 2 is arranged along water (flow) direction
On the water-drawing channel ontology 1, projection of the settling pit 2 in its vertical section is with the low-lying topography in its vertical section
Interior projection is adapted, and passes through the folder of the precipitation removal ultra-specification of settling pit 2 into the folder sand flow of downstream water-drawing channel
It is husky.The application by be arranged on the water-drawing channel ontology 1 along water (flow) direction a projection on its vertical section with it is low
The adaptable settling pit 2 of projection of the depression gesture on its longitudinal section, and the folder sand flow into downstream water-drawing channel is made to pass through institute
The folder for the precipitation removal ultra-specification of settling pit 2 stated is husky.In this way, due to the settling pit 2 using with the low-lying topography
The structure that projection on its longitudinal section is adapted, consequently facilitating rapid construction, and basement process is also relatively simple, cost
Also less expensive.
In the above embodiment, in order to make settling pit 2 described herein adapt to complicated geological conditions, especially collapse
Sliding, subsidence area or saturated yielding area geological conditions, avoids settling pit 2 described herein from still capable of playing desilting when ground changes
Effect, while it is again unlikely be destroyed in settlement of foundation, settling pit 2 described herein being projected as in the horizontal plane is ellipse
Circle, the longitudinal axis of the elliptical long axis and the water-drawing channel ontology 1；The pool wall 3 of the settling pit 2 includes the pad of lower part
The concrete ballast layer 5 of layer 4 and top is provided with impervious barrier 6 in the junction of the bed course 4 and the concrete ballast layer 5；
The impervious barrier 6 is anti-seepage geomembrane；Wearing layer 7 is there also is provided on the upper surface of the concrete ballast layer 5, at this time institute
The preferred structure for stating wearing layer 7 is high-strength abrasion-proof concrete layer.
Further, in order to enable settling pit Reusability described herein, to adapt to the water-drawing channel of the application,
The bottom of the settling pit 2 is provided with sand discharge outlet 8, at this point, the optimum position of 8 arrangement of sand discharge outlet is described to be arranged in
Settling pit 2 is located at the bottom outside of upstream side, i.e., at the return water sedimentation after flow high speed inflow settling pit.In this way, sedimentation is super
Ticket holder sand can be at any time by 8 discharge of the sand discharge outlet settling pit 2, will not with the settling pit 2 for ensureing described
The folder sand settled at any time fills up.
In conclusion the heavy water provided by the present application for being arranged in the geotechnological membrane structure on water-drawing channel ontology along water (flow) direction
Pond is combined due to geotechnological membrane structure with concrete ballast layer compared with the settling pit for using concrete structure in the prior art
The basis of composite construction settling pit is more adaptable to complex geological condition, and makes full use of the orographic condition of hypsography low-lying, can
To build the larger desilting structure of storage capacity, and basis is not required to using processing modes such as pile foundation, foundation replacements.When encountering flood or mud
When rock glacier, even if geomembrane desilting pool structure is silted stifled, destruction, the later stage also allows for repair and maintenance, and invests relatively province, duration more
It is short.
