Description
Technical field
The utility model relates to a kind of collecting gutter with anti-filter drain function, belongs to plumbing technical field, is specially adapted to the earth dam in large and medium water power station engineering, Tailings Dam or loose rock dam plumbing.
Background technology
Earth and rockfill dam is a kind of dam type applied in current Dam constructions widely, is common in the engineering field such as Hydraulic and Hydro-Power Engineering, Tailings Dam.Percolating water stream in earth and rockfill dam dam body or the dam foundation is monitored, collects and processed, very important to the safe operation of earth and rockfill dam.How effectively to monitor, collect, the infiltration current carried in dam body, be always earth-rock works need solve a difficult problem.For realizing effective collection of rainwater, being mostly provided with rainwater-collecting on roadbed side at present or crossing consideration measure.Such as, publication number is that the Chinese patent of CN2883464Y discloses a kind of highway structure realizing rainwater-collecting recycling, and comprise road base layer and road surface, wherein road surface is for can ooze road surface, is every infiltration layer between itself and road base layer; Road base layer is positioned at more than stratum soil, it is every infiltration layer, is made up, for can ooze road surface more than infiltration layer of waterproofing materials; In above-mentioned three layer construction both sides, dug zanjon along the bearing of trend of highway, the stratum soil surface in this zanjon and the section of road base layer are equipped with every infiltration layer, every infiltration layer and above-mentioned road base layer and should can ooze being connected as a single entity every infiltration layer between road surface; Bottom zanjon, highway bearing of trend is provided with longitudinal drainage pipe, this longitudinal drainage pipe body is distributed with aperture; Connect one at a certain distance along this longitudinal drainage pipe bearing of trend and intersect with it the transverse drain communicated, this transverse drain stretches out beyond zanjon; Fill with anti-filter fabric around longitudinal drainage pipe, be permeable filler above anti-filter fabric, permeable filler top layer is spill, and this spill is collecting gutter, and the height at collecting gutter top is lower than oozing road crust.The water side of gutter connects filtration, purification, the storage reutilizing device of rainwater.This highway structure effectively can collect rainwater, for control rainwater to the pollution of soil and underground water, realize rain water reuse precondition be provided.But the filtration in this technical scheme adopts anti-filter fabric, and easy breakage causes silting, be only applicable to collect the relative clean current such as rainwater on road surface, be not suitable for and collect infiltration current in rockfill; Do not meet rockfill include compared with coarseparticulate and permeate the higher anti-filter requirement of current.
For another example, publication number is the highway that the Chinese patent of CN201835205U discloses a kind of collecting by filtration rainwater on road surface, it comprises highway bed course, highway bed course is provided with impervious barrier, impervious barrier is provided with highway surface layer, the longitudinal drainage pipe along highway direction is provided with in the side of highway bed course or impervious barrier, on the tube wall of longitudinal drainage pipe, interval is provided with collection hole, and on longitudinal drainage pipe interval be connected with transverse drain, one end of transverse drain is communicated with longitudinal drainage pipe, and its other end extends outside highway; Be provided with anti-filter lamination in the outside of longitudinal drainage pipe, anti-filter lamination is provided with pervious layer, the structure of collecting gutter is formed on the top of pervious layer, and collecting gutter is provided with replaceable primary filter block.This technical scheme adopts and arranges in the side of highway the pipeline can collecting rainwater, collects again, can effectively filter the pollutants such as leaf, rubbish and suspended particulate, can obtain the rainwater of higher water quality after first rainwater being carried out primary filter.But adopt anti-filter lamination in this technical scheme but not geotextiles, can not anti-filter relatively fine particle, easily produce alluvial; The anti-filter problem of relatively fine particle thing can not be solved; Collecting gutter top can not be met and also need to bear the load-bearing requirements that follow-up roller compaction construction and enrockment bring.
Utility model content
For solving the problem, the utility model provides a kind of collecting gutter with anti-filter drain function.Effectively collect and carry the infiltration current in earth and rockfill dam, and then realizing to the Real-Time Monitoring of seepage flow situation in earth and rockfill dam with to collection and the process of permeating current.
The utility model is achieved by following technical solution.
A kind of collecting gutter with anti-filter drain function; comprise the ditch groove be positioned on dam foundation base surface; described ditch groove is arranged in dam body enrockment; groove top, described ditch is provided with ditch cover plate; ditch cover plate is furnished with some drain holes; described ditch cover plate is provided with loaded filter, outside described ditch groove, ditch cover plate and loaded filter, is all enclosed with topping, and topping is near inside dam body enrockment.
Described collecting gutter groove adopts steel concrete to make, and strength grade of concrete is more than or equal to C20.
The structural thickness of described ditch groove is more than or equal to 20cm, and arrangement of reinforcement is double steel bar.Arrangement of reinforcement can calculate according to groove dimensions and determine in actual applications.
Inside the groove of described ditch, flow-passing surface is coated with and is brushed with anti-corrosion material.
Described collecting gutter cover plate adopts prefabricated reinforced concrete to make, and strength grade of concrete is more than or equal to C20.
The structural thickness of described collecting gutter cover plate is more than or equal to 20cm, and arrangement of reinforcement is double steel bar.
The aperture of the drain hole that described collecting gutter cover plate is arranged is more than or equal to 10cm, and pitch of holes is more than or equal to 20cm.
Described loaded filter adopts blind material or makes at blind material outsourcing geomembrane.
Described topping adopts medium coarse sand or graded broken stone to make, and thickness is more than or equal to 30cm.
The beneficial effects of the utility model are:
Compared with prior art, the collecting gutter structure of pattern described in the utility model, its each structure can be cast-in-place or prefabricated, convenient and quick construction; Simultaneously by arranging loaded filter, can effectively collect and carry infiltration current in dam body, and then realize, to the Real-Time Monitoring of seepage flow situation in earth and rockfill dam with to collection and the process of permeating current, forming available protecting by topping to collecting gutter simultaneously.Collecting gutter described in the utility model is placed in rockfill, and percolating water fails to be convened for lack of a quorum a large amount of particle, due to anti-filter fabric (geotextiles) be easily worn destroy and lose anti-filter function; After therefore blind material is set, can comparatively coarseparticulate in filtered water stream, prevent particle from entering collecting gutter and cause silting, and there is shaping and voltage endurance capability preferably.
