Abstract
The utility model provides an underwater concrete crack repairing structure, which comprises a protection tube and a non-woven geotextile; the edge of the protection pipe is in a flat plate shape, the middle of the protection pipe is provided with an arc-shaped bulge, the non-woven geotextile is fixed on the inner wall of the arc-shaped bulge in the middle of the protection pipe, the arc-shaped bulge of the protection pipe is provided with an opening, the arc-shaped bulge of the protection pipe is over against the expansion joint of the concrete panel, and filler is filled in a space formed by the arc-shaped bulge of the protection pipe and the concrete panel. The materials used by the utility model are convenient to purchase and manufacture in the market; by utilizing external water pressure, if cracks appear in the protective cover, water penetrating through the quincuncial holes carries the fly ash to flow through the cracks, the cracks at the positions can be automatically filled with the fly ash, and meanwhile, the non-woven geotextile in the protective cover plays a role in reverse filtration for preventing the fly ash from flowing outwards.
Description
Technical field
The utility model relates to a kind of underwater concrete cracks to repair structure, belong to water conservancy and hydropower applied technical field.
Background technique
For the deformation requirements of consideration and concrete slab easy for construction, several expansion joints are artificially set in face dam, it should
Antiseepage at expansion joint uses copper sheet or other materials sealing.When the runtime, since stress changes, concrete face rockfill dam
Expansion joint or its periphery may generate harmful cracks.If the crack location is located under water, dry work is generally understood.This is applied
Work looks require be relatively inaccessible to, if it is necessary to reduce dam reservoir level, then mean greatly to waste waterpower resourses, very without
Ji.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of underwater concrete cracks reparation structure, this is underwater
Distress in concrete, which repairs structure, can effectively solve or repair expansion joint and its peripheral part harmful cracks between panel, improve dam body peace
Quan Xing facilitates the operational management of dam.
The utility model is achieved by the following technical programs.
A kind of underwater concrete cracks provided by the utility model repair structure, including protection pipe, nonweaven geotextile；Institute
Stating protection pipe edge is tabular, and there is arcuation protrusion at middle part, and nonweaven geotextile is fixed in the middle arc protrusion of protection pipe
On wall, there is aperture on the arcuation convex portion of protection pipe, the expansion joint of the arcuation convex portion face concrete slab of protection pipe,
There is filler in the space that the arcuation convex portion and concrete slab of protection pipe are formed.
Arcuation protrusion in the middle part of the protection pipe is semicircle or hemisphere figure shape.
The filler is flyash.
The aperture is in array distribution.
The open-ended of the protection pipe is closed by concrete backfill.
The tabular edge of the protection pipe has bolt that protection pipe is fixed on concrete slab.
The tabular edge width of the protection pipe is 1m.
The protection pipe with a thickness of 1mm.
The aperture of the aperture is Ф 10.
The utility model has the beneficial effects that: material therefor facilitates production in the market convenient for purchase；Utilize outer hydraulic pressure
Power flows through herein, flyash can fill at this automatically if occurring crack in protective cover through the water carrying flyash of plum blossom hole
Crack, while the nonweaven geotextile in protective cover plays the reverse filter effect for preventing flyash from outflowing again；Fine coal in protective cover
Ash plays the role of filling and repairs crack, effectively eliminates the hidden danger of dam, avoids by reducing the dry of reservoir level
Ground construction method mends a split；In the long run, there is significant economic benefit and social benefit.
Detailed description of the invention
Fig. 1 is the schematic diagram of the section structure of the utility model；
Fig. 2 is the planar structure schematic diagram of the utility model.
In figure: 1- protection pipe, 2- nonweaven geotextile, 3- bolt, 4- concrete slab, 5- flyash, the expansion joint 6-, 7-
Aperture.
Specific embodiment
Be described further below the technical solution of the utility model, but claimed range be not limited to it is described.
A kind of underwater concrete cracks as shown in Figure 1 and Figure 2 repair structure, including protection pipe 1, nonweaven geotextile 2；
1 edge of protection pipe is tabular, and middle part has arcuation raised, and the middle arc that nonweaven geotextile 2 is fixed on protection pipe 1 is convex
It rises on inner wall, there is aperture 7, the arcuation convex portion face concrete slab 4 of protection pipe 1 on the arcuation convex portion of protection pipe 1
Expansion joint 6, protection pipe 1 arcuation convex portion and concrete slab 4 formed space in have filler.
The arcuation protrusion at 1 middle part of protection pipe is semicircle or hemisphere figure shape.
The filler is flyash 5.
The aperture 7 is in array distribution.
The open-ended of protection pipe 1 is closed by concrete backfill.
The tabular edge of the protection pipe 1 has bolt 3 that protection pipe 1 is fixed on concrete slab 4.
The tabular edge width of the protection pipe 1 is 1m.
The protection pipe 1 with a thickness of 1mm.
The aperture of the aperture 7 is Ф 10.
