Description
Technical field
A kind of coating bank protection discharge structure is the utility model is related to, belongs to Hydraulic and Hydro-Power Engineering field of structural design.
Background technology
Water is an important factor for causing bank protection unstability, to cause following adverse effect：Water in slopes will cause slopes knot
Structure deadweight increase, bank protection sliding force also accordingly increase；Water in slopes can reduce the physics characteristic of slopes structure, reduce bank protection
Stability；Underground water produces hydrostatic pressure in slopes, penetration influences slope stability." controlling slope first to harness the river ", for bank protection work
Cheng Eryan, generally top-priority is processing to water, i.e., how to prevent rainwater and domatic water enters to blend and how reduced in slopes
Portion's level of ground water.
Existing bank protection drainage system is typically employed in the domatic upper end of bank protection slopes and sets intercepting ditch, and the domatic lower end of slopes is set
Gutter is put, the slopes between intercepting ditch and gutter are domatic to be provided with concrete layer, and multiple slope tables are provided with concrete layer
Osculum, and arrange scupper below bank protection deep implication face.Such structure, can be with due to the arrangement of top intercepting ditch
Domatic water more than protective range is blocked into carrying-off, will not being further continued for flowing down, it is stable to influence bank protection；Domatic closed concrete layer
Setting, prevent domatic water from continuing to infiltrate；The arrangement of bank protection osculum can discharge the underground water of slope surface；Slopes lower end
Gutter can drain the domatic water in protective range；Scupper can arrange the deep phreatic water that drainpipe can not discharge
Go out.But when bank protection is coating, and project scale is less than normal, removing coating investment is larger, also without scupper in coating
Cavitation condition, domatic arrangement water drainage is also easily blocked by stream soil, so as to which underground water can not discharge in time inside bank protection, bank protection
Stability will be lost in by underground water and grogs and be influenceed and deteriorated, cause damage.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of coating bank protection discharge structure, coating shield
Slope discharge structure is reached by the arrangement of geosynthetics draining material, anti-filter geotextile and drainpipe in top of the slope intercepting ditch, slope
Discharge the purpose of underground water in coating bank protection surface and slope.
The utility model is achieved by the following technical programs.
A kind of coating bank protection discharge structure provided by the utility model, including bank protection, coating and gutter；The shield
Slope is located at the side of coating, and the opposite side of bank protection is connected with gutter；The bottom of the bank protection is provided with drainpipe and anti-filter soil
Work fabric, is provided with geosynthetics draining wall on the side inwall of bank protection, and the upper inner wall of bank protection is provided with intercepting ditch；The draining
Pipe is embedded in anti-filter geotextile.
The crest level of the geosynthetics draining wall is less than phreatic line.
The drainpipe has two.
Two drainpipes are parallel to each other.
The intercepting ditch burial place is higher than phreatic line.
The anti-filter geotextile is trapezoidal.
The beneficial effects of the utility model are：
(1) anti-filter geotextile can prevent fine grained in coating bank protection from as osculum oozes out, preventing coating in slope
Grogs is lost in；
(2) by draining inside and outside geosynthetics draining material in top of the slope intercepting ditch and slope, drainpipe, surface water can effectively be discharged
With the underground water in slope, so that the inside and outside of bank protection is in drainage state, reduce due to underground water pair inside bank protection
The influence of slopes structure physical property, improve the stability of bank protection；
(3) it is more aesthetically pleasing to reduce draining hole drilling amount, bank protection on bank protection；
(4) domatic water is prevented to infiltrate by bank protection.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is structure partial drawing of the present utility model；
In figure：1- intercepting ditch, 2- bank protections, 3- coatings, 4- drainpipes, 5- geosynthetics draining walls, 6- gutters, 7- are anti-
Filter geotextile.
Embodiment
Be described further below the technical solution of the utility model, but claimed scope be not limited to it is described.
As depicted in figs. 1 and 2, a kind of coating bank protection discharge structure, including bank protection 2, coating 3 and gutter 6；It is described
Bank protection 2 is located at the side of coating 3, and the opposite side of bank protection 2 is connected with gutter 6；The bottom of the bank protection 2 is provided with drainpipe 4
With anti-filter geotextile 7, geosynthetics draining wall 5 is provided with the side inwall of bank protection 2, the upper inner wall of bank protection 2, which is provided with, cuts
Ditch 1；The drainpipe 4 is embedded in anti-filter geotextile 7.
Wherein, the crest level of the geosynthetics draining wall 5 is less than phreatic line, prevents coating grogs from being lost in；Institute
Stating drainpipe 4 has two, can effectively discharge the underground water in surface water and slope, so that bank protection 2 is inside and outside in thin
Dry state, reduces the stability for due to influence of the inside underground water of bank protection 2 to slopes structure physical property, improving bank protection 2；
