Abstract
The utility model relates to an inlet plugging device for a temporary buried pipe in a dense dam body. The device comprises a buried pipe, wherein a concrete dam body is arranged at the outer side of the buried pipe, a wedge groove with a large outer opening and a small inner opening is arranged in the concrete dam body of the inlet of the buried pipe, two annular water stopping plates are arranged on the temporary buried pipe buried in the dam body, and the wedge groove is backfilled densely with concrete in the later period. According to the device, the construction is simple and convenient, the burying quality of the temporary buried pipe is guaranteed, the construction need of the dam body is satisfied, the concrete dam body quality is guaranteed at the same time, and external water can be effectively prevented from entering the dam body and leaking along a buried temporary pipeline.
Description
Technical field
The utility model relates to a kind of dam body pipe laying inlet device, relates in particular to the interim pipe laying import plugging device in a kind of closely knit dam body.
Background technology
At water power building concrete dam dam body work progress; For making things convenient for the dam body construction drainage; Be everlasting and bury the interim construction drainage pipe that runs through dam body underground in the dam body, when the dam body construction of corresponding site finishes, the temporary drainage pipe must shutoff; For the gutter shutoff leakiness that prevents to bury underground in the dam body becomes penetrating passage of dam body temporarily, cause the dam body hidden danger of quality.
Summary of the invention
The technical problem that the utility model will solve provides a kind of simple in structure, and construction effect is good, prevents that secondary water from getting into the interim pipe laying import plugging device of dam body along the temporary pipeline seepage of burying underground.
The purpose of the utility model is achieved in that the interim pipe laying import plugging device in a kind of closely knit dam body; It comprises steel pipe; The steel pipe outside is a concrete dam body; On the concrete dam body of steel pipe import, be provided with wedge-shaped slot, the steel pipe outside of wedge-shaped slot rear end is provided with annular seal plate, and backfill has concrete in the wedge-shaped slot.The wedge-shaped slot collar extension is big, in young.Filled closely knit concrete in the described wedge-shaped slot.
Technique effect below the utility model has been obtained:
1, the utility model construction is simple and convenient, has guaranteed that interim pipe laying buries quality underground, satisfies dam body construction needs, has also guaranteed the concrete dam body quality simultaneously, can prevent effectively that secondary water from getting into dam body along the temporary pipeline seepage of burying underground.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the sketch map of the utility model.
Fig. 2 is the left view of Fig. 1.
The specific embodiment
Shown in Fig. 1-2; Interim pipe laying import plugging device in a kind of closely knit dam body; It comprises steel pipe 1, and the steel pipe outside is a concrete dam body, on the concrete dam body of steel pipe import, is provided with wedge-shaped slot 4; The steel pipe outside of wedge-shaped slot 4 rear ends is provided with annular seal plate 2,3, and backfill has concrete 5 in the wedge-shaped slot 4.Wedge-shaped slot 4 collar extensions are big, in young.Filled closely knit concrete in the described wedge-shaped slot 4.
The reservation wedge-shaped slot of the utility model is arranged on the gutter entrance location, and wedge-shaped slot collar extension imperial palace is young, and it is reserved about the general 100cm of degree of depth, the admission section size with make things convenient for preformed groove, pipe laying grouting with and backfill construction conveniently be as the criterion; The concrete of wedge-shaped slot and backfill thereof is after it receives external hydraulic action, and it is tightr that the concrete of backfill is combined with whole dam concrete as stopper, prevention secondary water entering dam body.Twice annular steel sealing is welded on the interim pipe laying of dam body, in pipe laying is embedded in concrete dam body, is used for preventing stoping infiltration to be extended to dam body inside along pipe laying just in case there is secondary water to leak into the pipe laying position, forms penetrating passage.Pipe laying in being embedded in dam body is finished using, and with mortar or cement paste pipe laying is poured into closely knitly, and the pipe laying section that will be exposed at wedge-shaped slot is then cut off, and is to wedge shape groove face hacking, clean out, with concrete that the wedge-shaped slot shutoff is closely knit.
The utility model construction utilizes process to implement according to following four steps:
1, makes the dam body pipe laying
Bury the water pipe plan according to dam body, carry out pipe arrangement, and weld twice steel plate water-stopping ring in dam body pipe laying import appropriate location.
2, the dam body pipe laying is installed
Treat that dam body is poured into design altitude,, the pipe laying layout is put in place, and the young wedge-shaped slot template of the collar extension imperial palace that will design and produce is in place according to dam body pipe laying plan.Treat that each operation delivery receiving acceptance finishes, build this storehouse concrete, will use piping laying in concrete temporarily.
3, the interim pipe laying grouting of dam body
Finish using when the interim pipe laying of dam body, pipe port is shut, and at shutoff plate upper shed welding grouting slurries turnover arm with steel plate, closely knit through the grouting arm then to the pipe laying perfusion of being in the milk.
4, reserve the wedge-shaped slot shutoff
After the interim pipe laying grouting of dam body is closely knit, remove being exposed at the pipe laying of reserving wedge-shaped slot, and will reserve wedge shape groove face hacking and clean out, behind the installation and design reinforcing bar formwork erection, the wedge-shaped slot backfill is closely knit with concrete.
This device is successful Application in Three Gorges Projects, and construction is simple, has guaranteed dam body pipe laying quality; Satisfied the functional requirement of dam body pipe laying; Effectively stoped along the penetrating passage of dam body pipe laying, guaranteed the dam concrete quality, practiced thrift construction cost; Satisfy whole dam body construction requirement, obtained good effect.
