The easily destroyed risk of structure.Therefore, treatment in accordance with local conditions, just becomes this area using reasonable, economic, practical desilting pool structure
Technical staff builds the technical problem that water-drawing channel must take under above-mentioned complex geological condition.
Utility model content
Technical problem to be solved in the utility model is: rapid construction, basement process be simple, cost to provide one kind to be easy to
The cheap water-drawing channel structure for complex geological condition area.
Be the technical scheme is that a kind of flume for complex geological condition area by solving above-mentioned technical problem
Road structure, including the water-drawing channel body being arranged at low-lying physical features, described water-drawing channel structure also includes settling pit, described
Settling pit be arranged on described water-drawing channel body along water (flow) direction, projection in its vertical section for the described settling pit and institute
State projection in its vertical section for the low-lying physical features to be adapted, the husky current of folder entering downstream water-drawing channel pass through described settling pit
The folder that precipitation removes ultra-specification is husky.
The beneficial effects of the utility model are: the application passes through to arrange on described water-drawing channel body along water (flow) direction
The settling pit that one projection in the projection in its vertical section and low-lying physical features in its vertical part surface is adapted, and make entrance downstream
The folder that the husky current of folder of water-drawing channel pass through described settling pit precipitation removal ultra-specification is husky.So, due to described settling pit
Use the structure that the projection in its vertical section is adapted with described low-lying physical features, consequently facilitating rapid construction, and ground
Base is processed also relatively simply, and cost is also less expensive.
Be further, described settling pit in the horizontal plane be projected as ellipse, described oval major axis is drawn with described
The longitudinal axis of water channel road body.
It is further that the pool wall of described settling pit includes the bed course of bottom and the concrete ballast layer on top, described
Bed course is provided with impervious barrier with the junction of described concrete ballast layer.
It is further that described impervious barrier is anti-seepage geomembrane.
It is further to there also is provided wearing layer on the upper surface of described concrete ballast layer.
It is further that described wearing layer is high-strength abrasion-proof concrete layer.
It is further that the bottom sinking in described desilting is provided with sand discharge outlet.
It is further that described sand discharge outlet is arranged in the bottom outside that described settling pit is located at upstream side.
Brief description
Fig. 1 is used for the site plan of the water-drawing channel structure in complex geological condition area for this utility model；
Fig. 2 is the a-a sectional view of Fig. 1；
The sectional view of the settling pit pool wall that Fig. 3 is related to for the application.
In figure is labeled as: water-drawing channel body 1, settling pit 2, pool wall 3, bed course 4, concrete ballast layer 5, impervious barrier 6, resistance to
Mill layer 7, sand discharge outlet 8.
Specific embodiment
As shown in Figure 1, Figure 2 and shown in Fig. 3 be one kind that this utility model provides be easy to rapid construction, basement process simple,
The water-drawing channel structure for complex geological condition area of low cost.Described water-drawing channel structure includes being arranged in low-lying
Water-drawing channel body 1 at physical features, described water-drawing channel structure also includes settling pit 2, and described settling pit 2 is along water (flow) direction
It is arranged on described water-drawing channel body 1, projection in its vertical section for the described settling pit 2 is vertical at it with described low-lying physical features
Projection in section is adapted, and the husky current of folder entering downstream water-drawing channel remove ultra-specification by described settling pit 2 precipitation
Folder husky.The application passes through to arrange a projection in its vertical section on described water-drawing channel body 1 along water (flow) direction
The settling pit 2 being adapted with projection in its vertical section for the low-lying physical features, and so that the folder sand current of entrance downstream water-drawing channel is led to
Cross the folder sand that described settling pit 2 precipitation removes ultra-specification.So, due to described settling pit 2 use low-lying with described
The structure that projection on its longitudinal section for the physical features is adapted, consequently facilitating rapid construction, and basement process is also relatively simple,
Cost is also less expensive.
In above-mentioned embodiment, in order that settling pit described herein 2 adapts to the geological conditions of complexity, especially collapse
The geological conditions in cunning, subsidence area or saturated yielding area, it is to avoid settling pit 2 described herein still can play desilting when ground changes
Effect, simultaneously again unlikely destroyed in settlement of foundation, settling pit 2 described herein being projected as in the horizontal plane is ellipse
Circle, the longitudinal axis of described oval major axis and described water-drawing channel body 1；The pool wall 3 of described settling pit 2 includes the pad of bottom
Layer 4 and the concrete ballast layer 5 on top, are provided with impervious barrier 6 in the junction of described bed course 4 and described concrete ballast layer 5；
Described impervious barrier 6 is anti-seepage geomembrane；The upper surface of described concrete ballast layer 5 there also is provided wearing layer 7, now institute
The preferred structure stating wearing layer 7 is high-strength abrasion-proof concrete layer.
Further, in order that desilting described herein sink can Reusability, to adapt to the water-drawing channel of the application,
The bottom of described desilting heavy 2 is provided with sand discharge outlet 8, and now, the optimum positions of described sand discharge outlet 8 arrangement are described in being arranged in
Settling pit 2 is located at the bottom outside of upstream side, at the backwater sedimentation after that is, current flow at a high speed settling pit.So, sedimentation is super
Ticket holder sand just can be reached by described sand discharge outlet 8 and discharge described settling pit 2, will not with the settling pit 2 ensureing described
The folder sand being settled at any time fills up.
In sum, the heavy water of the geotechnological membrane structure being arranged in along water (flow) direction on water-drawing channel body that the application provides
Pond, compared with prior art using the settling pit of xoncrete structure, is combined with concrete ballast layer due to geotechnological membrane structure
The basis of composite construction settling pit is higher to complex geological condition adaptability, and makes full use of the orographic condition of hypsography low-lying, can
The desilting structure larger to build storage capacity, and basis is not required to using processing modes such as pile foundation, foundation replacements.When running into flood or mud
During 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
Short.
