Embodiment Construction

[0018] The technical solution of the present invention is further described below, but the scope of protection is not limited to the description.

[0019] Such as figure 1 , figure 2 A panel dam crack repair structure shown includes a protective tube 1 and a non-woven geotextile 2; the edge of the protective tube 1 is flat and has an arc-shaped protrusion in the middle, and the non-woven geotextile 2 is fixed in the middle of the protective tube 1 On the inner wall of the arc-shaped protrusion, there is an opening 7 on the arc-shaped protrusion of the protection tube 1, the arc-shaped protrusion of the protection tube 1 is facing the expansion joint 6 of the concrete panel 4, and the arc-shaped protrusion of the protection tube 1 and the concrete panel 4 There is a filler in the space formed.

[0020] The arc-shaped protrusion in the middle of the protection tube 1 is in the shape of a semicircle or a hemisphere.

[0021] The filler is fly ash5.

[0022] The openings 7 ar...

Abstract

The invention provides a faceplate dam crack repairing structure. The faceplate dam crack repairing structure comprises a protection pipe and a nonwoven geotextile; the side edge of the protection pipe is in a flat plate shape; an arc-shaped bulge is arranged on the middle part of the protection pipe; the nonwoven geotextile is fixed onto the inner wall of the arc-shaped bulge on the middle part of the protection pipe; open holes are formed in an arc-shaped bulge part of the protection pipe; the arc-shaped bulge part of the protection pipe directly faces an expansion joint of a concrete panel;and a filler is arranged in a space formed by the arc-shaped bulge part of the protection pipe and the concrete panel. According to the faceplate dam crack repairing structure provided by the invention, the used materials are convenient to purchase in the market and convenient to manufacture; by utilizing external water pressure, if a crack occurs in a protection cover, water penetrating throughplum blossom holes carries pulverized fuel ash to flow through the crack, so that the crack can be automatically filled with the pulverized fuel ash; and meanwhile, the nonwoven geotextile in the protection cover can play a filtering role in preventing the pulverized fuel ash from flowing out.

Description

technical field [0001] The invention relates to a crack repair structure of a face dam, which belongs to the technical field of water conservancy and hydropower applications. Background technique [0002] Considering the convenience of construction and the deformation requirements of the concrete face, several expansion joints are artificially set in the face dam, and the anti-seepage at the expansion joints uses copper sheets or other materials to stop water. During the operation period, due to the change of the force, harmful cracks may occur in the expansion joints of the concrete face dam or its surroundings. If the crack location is underwater, it will generally be constructed dry. It is difficult to meet the requirements of this construction appearance. If the water level of the dam reservoir must be lowered, it means a great waste of hydraulic resources, which is very uneconomical. Contents of the invention [0003] In order to solve the above technical problems, ...
