Abstract
The utility model discloses the structure of a kind of concrete plug backfill grouting, it is to be hoop to distribute more than two backfill grouting supervisor (2) is set at concrete plug (1) crown position, and every backfill grouting supervisor's (2) both sides are extended two and above are responsible for backfill grouting the grouting arm (3) that (2) intersect; Be provided with a stack (4) that stretches into plug inside in the top of concrete plug (1), be respectively provided with an expansion waterstop (5) for grouting at the top at the two ends of concrete plug (1).The utility model carries out backfill grouting by replacing traditional backfill grouting gallery at the pre-buried backfill grouting pipe in concrete plug top to concrete plug top, and working procedure is simple, quick construction is convenient, technology is reliable.
Description
Technical field
The utility model relates to a kind of structure that solves the backfill grouting of concrete plug, belongs to Hydraulic and Hydro-Power Engineering technical field.
Background technology
At present, at home in hydroelectric project, Ni Po as genial in bridge in lattice power station, after Diversion Tunnel or a construction hole concrete plug have been constructed, concrete plug is carried out to backfill grouting, generally inner reserved irrigation gallery during concrete plug body construction, according to grouting construction requirement, irrigation gallery size is generally 3 × 3.5m(wide × height).When concrete plug possess backfill grouting condition be take grouting equipment by irrigation gallery injection backfill grouting hole to reach backfill grouting object.According to hydroelectric project feature, for reaching as early as possible dash object, the concrete plug engineering construction duration is generally very nervous, in the time that constructing, concrete plug reserves irrigation gallery therein, need installation form, assembling reinforcement etc., working procedure complexity, the construction period is longer, take effective construction period of concrete plug, had a strong impact on the construction speed of concrete plug; In addition, the backfill grouting post-grouting gallery of having constructed need carry out just carrying out concrete backfill after dabbing, has strengthened engineering human and material resources and has dropped into, and has increased construction investment.Therefore, the technical measures of existing concrete plug backfill grouting or not ideal enough, await further perfect.
Utility model content
The purpose of this utility model is as overcoming the deficiencies in the prior art, the structure of a kind of concrete plug backfill grouting is provided, can ensure concrete plug backfill grouting construction quality by pre-buried backfill grouting pipe and expansion waterstop, construction technology is simple simultaneously, quick construction convenient, accelerate the concrete plug construction period, save human and material resources resource and drop into, reduce construction cost.
The purpose of this utility model is achieved by following technical solution:
The structure of concrete plug of the present utility model backfill grouting, comprise concrete plug, be hoop distribution at this concrete plug crown position more than two backfill grouting supervisors is set, every backfill grouting supervisor's both sides are extended two and above be responsible fors with backfill grouting the grouting arm intersecting, and the slurries of grouting can flow in arm by being responsible for; Be provided with a stack that stretches into plug inside in the top of concrete plug, exhaust when stack is used for grouting construction, is respectively provided with an expansion waterstop for grouting at the top at the two ends of concrete plug.
Further, backfill grouting supervisor and stack adopt cleek to be fixed on concrete plug crown position.The quantity of cleek will guarantee to fixedly secure backfill grouting supervisor and stack.
Further, backfill grouting supervisor, grouting arm and stack are pvc pipe or PE pipe.Certainly, also can adopt other operable grouting pipeline in engineering.
The beneficial effects of the utility model are:
Compared with prior art, the utility model carries out backfill grouting by replacing traditional backfill grouting gallery at the pre-buried backfill grouting pipe in concrete plug top to concrete plug top, and working procedure is simple, quick construction is convenient, technology is reliable; By the pre-buried backfill grouting arm of being responsible for and being in the milk, when grouting construction, guarantee better fill concrete plug apex cavity of slurries, guarantee backfill grouting construction quality; When backfill grouting construction, slurries will squeeze the gas at concrete plug crown position, and gas is drained by the stack of top; Plug two ends adopt expansion waterstop grouting, after waterstop is met water, expand, and concrete plug apex cavity is played to good sealing effectiveness, guarantee that slurries can seepage; Backfill grouting pipe Embedment Construction technique is simple, and the later stage does not need to remove, and can not affect the operation of concrete plug engineering safety; Backfill grouting pipe and stack are generally taked PVC or PE pipe, and market plane is easy to buying, invest littlely, and backfill grouting pipe is for higher hardness, can not produce deformation and failure when backfill grouting, can ensure backfill grouting quality; Cleek is easy to construction, can preferably backfill grouting pipe and stack be fixed on to concrete plug top.The utility model construction technology is simple, and constructability is economic and practical, can be in Construction for Hydroelectric Project technical field wide popularization and application.
brief description of the drawings
Fig. 1 is that the utility model plane is shown schematic diagram;
Fig. 2 is the A-A sectional drawing of Fig. 1.
In figure: 1-concrete plug, 2-backfill grouting supervisor, 3-backfill grouting arm, 4-stack, 5-expansion waterstop, 6-cleek.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, this grouting structure of the present utility model, comprise concrete plug 1 and be embedded in advance backfill grouting supervisor 2, grouting arm 3, stack 4 and the expansion waterstop 5 at concrete plug 1 top, backfill grouting supervisor 2 and stack 4 are fixed on concrete plug 1 top by cleek 6, and backfill grouting supervisor 2 is connected with grouting arm 3.Adopt these technical measures, directly backfill grouting supervisor 2 and grouting arm 3 are embedded in to concrete plug 1 top formation backfill grouting construction passage in advance, backfill grouting supervisor 2 and grouting arm 3 installation operations are simple, efficient and convenient, accelerating construction progress greatly, and the later stage does not need to remove, and does not affect 1 safe operation of concrete plug; Backfill grouting supervisor 2 and grouting arm 3 are easy to buying, invest littlely, have reduced construction cost.
As shown in Figure 1, the utility model is in the time implementing, first before 1 construction of concrete plug, backfill grouting supervisor 2, grouting arm 3, stack 4 and expansion waterstop 5 are embedded in to concrete plug 1 top in advance, wherein stack 4 is placed in top, expansion waterstop 5 is placed in concrete plug 1 crown two ends, backfill grouting supervisor 2 is connected with grouting arm 3, backfill grouting supervisor 2 and stack 4 are fixed to (as shown in Figure 2) by some cleeks 6.In the time that 1 concrete construction of concrete plug completes and reaches the pustulation period, to be responsible for 2 by backfill grouting and to be in the milk, slurries enter grouting arm 3 and are finally filled in the space of concrete plug 1 from backfill grouting supervisor 2, reach the object of backfill grouting.In the time of grouting construction, the gas in concrete plug 1 is discharged by stack 4, and grouting is sealed by expansion waterstop 5 in the two ends of concrete plug 1.
Certainly, be more than concrete exemplary applications of the present utility model, the utility model also has other embodiment, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, within all dropping on the desired protection domain of the utility model.
