Abstract
A quick processing device for a large-flow water leakage hole in a concrete body comprises a water drainage pipe installed at an opening of the water leakage hole, a ball valve installed at an outlet of the water drainage pipe, a long grouting pipe and a short grouting pipe, wherein the long grouting pipe and the short grouting pipe are welded to the inside of the water drainage pipe, the unwelded end, of a certain length, of the long grouting pipe extends into the water leakage hole, and the unwelded end of the short grouting pipe extends into the water drainage pipe. According to the quick processing device for the large-flow water leakage hole in the concrete body, the ball valve on the water drainage pipe is quickly closed, grouting is carried out through the short grouting pipe, the long grouting pipe is used for draining water, when slurry comes out from the long grouting pipe, the long grouting pipe and the short grouting pipe are simultaneously used for grouting, the two pipes are in parallel connection for grouting, and the anti-leakage aim is achieved. In the early stage of grouting, the long grouting pipe can be used for draining water all the time so that pressure of water in the water leakage hole cannot be excessively high and grouting cannot be influenced; according to the quick processing device, the processing principle that plugging is carried out during drainage and drainage is carried out during plugging is adopted, and the aim of quickly plugging the water leakage hole is achieved; the quick processing device is easy to manufacture and install and convenient to operate; the device is simple, practical and good in effect when the large-flow water leakage hole is processed.
Description
Technical field
The present invention relates to a kind of leakage treatment device, especially a kind of device that large flow leaking hole in concrete bodies is carried out to fast processing.
Background technology
In the engineering construction of water power concrete dam, often in order to meet dam construction phase water conservancy diversion, in dam bottom, interim Diversion Tunnel is set or pod apertures is carried out water conservancy diversion, when dam construction possesses dash condition to certain elevation, interim pod apertures (hole) shutoff is carried out in lower lock retaining.After lower lock retaining, upper pond hydraulic pressure raises, and in pod apertures under high Water Pressure (hole), leaking appears in construction quality weak part, and some positions even occur that large flow leaks, for meeting (hole) shutoff of water conservancy diversion bottom outlet and safety of dam body, must as early as possible leakage area be carried out to leak stopping processing.Because leakage area hydraulic pressure is high, flow velocity is fast, the water yield is large, and leakage area intractability is large, develops a kind of large flow quick treatment device that leaks in this situation.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of to large flow leaking hole quick treatment device in concrete bodies, can solve the water power concrete bodies flow that leaks large, the problem of leaking hole shutoff difficulty, realizes the shutoff to large flow leaking hole fast, simple and practical quick.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: one, to large flow leaking hole quick treatment device in concrete bodies, comprises the gutter that is arranged on leaking hole aperture, and gutter and aperture adopt leak stopping treasured or building viscose glue to seal water-tight; The ball valve that install at drainpipe outlet place; Long grout pipe and the short grout pipe of welding in gutter, long grout pipe not welding ends stretches into certain length in leaking hole, and short grout pipe not welding ends stretches in gutter.
Gutter be mainly used in leaking hole before starting to process to the discharge of leaking and other member installation needs; Ball valve is mainly used in closing gutter, to meet anti-seeping grouting processing requirements; Long grout pipe is mainly used in gutter upper ball valve and cuts out rear to the grouting in the discharge of leaking in leaking hole and Process of Leaking Stoppage; Short grout pipe is mainly used in anti-seeping grouting.
One provided by the invention is to large flow leaking hole quick treatment device in concrete bodies, by the ball valve on quick closedown gutter, first from short grout pipe grouting, long grout pipe draining, in the time of long grout pipe pulp, long grout pipe and short grout pipe are in the milk simultaneously, and two-tube parallel connection is in the milk, and reach leak stopping object.Early filling stage, the draining always of long grout pipe, makes hydraulic pressure in leaking hole be unlikely to too high impact grouting, is treatment principle with " stifled in row, stifled middle row ", reaches the object of fast blockage; Fabrication and installation are simple, easy to operate; This device is in the time processing large flow leaking hole, simple and practical, respond well.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is structural representation of the present invention.
The specific embodiment
As shown in Figure 1, the present invention includes the gutter 1 that is arranged on leaking hole 5 apertures, the ball valve 2 that install in gutter 1 exit, the long grout pipe 3 of gutter 1 interior welding and short grout pipe 4, long grout pipe 3 not welding ends stretches into the interior certain length of leaking hole 5, and short grout pipe 4 not welding ends stretches in gutter 1.
Installation of the present invention and use procedure are as follows:
1) to large flow leakage point on concrete bodies 6, first carry out drill hole reason, under leaking hole 5 aperture free discharge conditions, expand and expand deep hole mouth, fix a drainpipe 1 to facilitate in the aperture of leaking hole 5.
2) in leaking hole 5 apertures, a gutter 1 is installed, is adopted leak stopping treasured or building viscose glue by water-tight to gutter periphery and leaking hole 5 orifice sealings.
3) gutter 1 mouth of pipe mounting ball valve 2; The long grout pipe 3 of welding and short grout pipe 4 on gutter 1; Long grout pipe 3 is not more than welding ends stretches into the interior 2m of leaking hole 5, and short grout pipe 4 not welding ends stretches in gutter 1.During this installs each component assembling construction, the current that leak are drawn from gutter 1.
4) this device installs while starting to be in the milk, and the ball valve 2 on quick closedown gutter 1 is first in the milk from short grout pipe 4, long grout pipe 3 drainings, in the time of long grout pipe 3 pulp, long grout pipe 3 and short grout pipe 4 are in the milk simultaneously, two-tube parallel connection is in the milk, and reaches leak stopping object.Early filling stage, the draining always of long grout pipe 3, makes hydraulic pressure in leaking hole be unlikely to too high impact grouting, and this device is treatment principle with " stifled in row, stifled middle row ", reaches the object of fast blockage.
Claims (1)
1. to a large flow leaking hole quick treatment device in concrete bodies, comprise gutter (1), it is characterized in that: gutter (1) is arranged on leaking hole (5) aperture, and tight with orifice sealing; The exit of gutter (1) is provided with ball valve (2); On gutter (1), be welded with long grout pipe (3) and short grout pipe (4), long grout pipe (3) not welding ends stretches into the interior certain length of leaking hole (5), and short grout pipe (4) not welding ends stretches in gutter (1).
