Description
Technical field
The utility model relates to a kind of earth and rockfill dam spillway on bank and lets out groove foundation drainage structure, and particularly a kind of earth and rockfill dam spillway on bank being applied to Hydraulic and Hydro-Power Engineering technical field lets out groove foundation drainage structure.
Background technology
Flood spillway is the important component part in Hydraulic and Hydro-Power Engineering, carries out the percolating water current control on flood spillway basis, and the Water drainage system design especially carrying out Spillway chute basis is one of key factor ensureing that flood spillway engineering safety runs.
The infiltration current on Spillway chute basis mainly contain following several source: storehouse water infiltrates through flood spillway weir base and bank slope, bank slope underground water is infiltrated by bedrock fracture, let out groove under sluice and to infiltrate through base plate parting.The discharge structure design on Spillway chute basis must be carried out, generally by letting out vertical transverse drain ditch or the gallery excretion percolating water on groove basis, to reduce the osmotic pressure of letting out groove basis, gutter should take to prevent silting measure simultaneously, discharges in order to infiltration smooth in water flow.
Existing Spillway chute foundation drainage structure is generally: establish vertical and horizontal draining sewer pipe or collector drain at chute bottom slab.For gutter structure, generally first press design section excavation gutter, and adopt filter material or the levelling basal plane of non-fine concrete, prevent the blocking of convex body place, local gutter.In ditch, bury PVC floral tube or plastic blind-ditch underground again, floral tube outsourcing geotextiles anti-filter, or in gutter, directly bury UPVC pipe, prefabricated sand-free concrete tube underground, then fill out rubble anti-filter to chute bottom slab design altitude on gutter upper berth.Before chute bottom slab concreting, when the laying of gutter end face asphaltic felt or building paper etc. prevent chute bottom slab concrete construction, slurries infiltrate blocking gutter.
There are the following problems for prior art: one, design section size is generally tens centimetres to about 2 meters, basement rock excavates small size gutter like this, according to blasting method excavation, guarantee design section build, and blast working is difficult to control; According to hand excavation, then cost higher and duration is difficult to ensure; Two, construction sequence is complicated, and cost is high, and construction quality is difficult to control; Though three, gutter end face is laid asphaltic felt or building paper and can be prevented chute bottom slab concrete slurry from infiltrating gutter, asphaltic felt or building paper itself waterproof, cause the lower infiltration via chute bottom slab parting smooth and easyly not discharge, it is unfavorable to stablize chute bottom slab.Therefore also do not have a kind of simple and reasonable for structure, reliable in prior art, effectively can discharge the infiltration of Spillway chute basis, the earth and rockfill dam spillway on bank reducing chute bottom slab osmotic pressure lets out groove foundation drainage structure.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of simple and reasonable for structure, reliable, and effectively can discharge the infiltration of Spillway chute basis, the earth and rockfill dam spillway on bank reducing chute bottom slab osmotic pressure lets out groove foundation drainage structure.
For solving the problems of the technologies described above, the earth and rockfill dam spillway on bank that the utility model adopts lets out groove foundation drainage structure, and comprise gutter, the both sides in described gutter are provided with and grout stone walling.
Further, the inside paving in described gutter is filled with the cobble draining bed of material.
Further, described gutter end face is provided with geotextiles.
Further, described geotextiles two ends by bolt with grout stone walling and be connected.
The beneficial effects of the utility model are: first build stone masonry parapet by laying bricks or stones, then between stone masonry parapet, spread guanovulite draining material, and stone masonry parapet and cobble drainage are constructed and can be adapted to different gutter basement rock and excavate build.Stone masonry parapet and cobble gutter building stones used can be gathered materials on the spot, and construction technology is simple, can construct on a large scale.Chute bottom slab infiltration directly enters in earth and rockfill dam enrockment by vertical transverse drain ditch, and cobble draining material itself plays draining reverse filter effect, simple and practical.The geotextiles of gutter end face both can prevent chute bottom slab concrete slurry from infiltrating cobble draining material, infiltration current can be made again to enter cobble draining material, play filter sand drainage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Component, position and numbering in figure: gutter 1, grout stone walling 2, the cobble draining bed of material 3, geotextiles 4, bolt 5.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, earth and rockfill dam spillway on bank of the present utility model lets out groove foundation drainage structure, comprises gutter 1, and the both sides in described gutter 1 are provided with and grout stone walling 2.That sets up in both sides, gutter 1 grouts stone walling 2 and can repair gutter 1 section, makes it more press close to design section.During concrete enforcement, arrange vertical transverse drain ditch 1, vertical transverse drain ditch 1 is arranged in Spillway chute basis.
The inside paving in described gutter 1 is filled with the cobble draining bed of material 3.Spread in the inside in gutter 1 the cobble draining bed of material 3 filled out to repair gutter 1 section, make it more press close to design section.
Described gutter 1 end face is provided with geotextiles 4.
The two ends of described geotextiles 4 by bolt 5 with grout stone walling 2 and be connected.
During concrete enforcement, gutter 1 sequence of construction is: gutter 1 excavates → both sides grout stone walling 2 constructs → ditch in the cobble draining bed of material 3 paving fill out → gutter 1 end face geotextiles 4 lays → bolt 5 anchoring.Due to the reason such as Excavation blasting, construction control, gutter 1 section is generally difficult to coincide with design section, the utility model proposes first to build by laying bricks or stones in both sides, gutter 1 and grout stone walling 2, between stone masonry parapet, spread the guanovulite draining bed of material 3 again, stone masonry parapet and cobble draining material can play repairing effect to actual excavation face.The geotextiles 4 of gutter 1 end face both can prevent chute bottom slab concrete slurry from infiltrating cobble draining material, infiltration current can be made again to enter cobble draining material, play filter sand draining " effect.Stone masonry parapet and cobble draining material building stones used of constructing can be gathered materials on the spot, and construction technology is simple, can construct on a large scale.
