Embodiment 1

[0027] Embodiment 1, a kind of water conveyance aqueduct structural seam leak repair structure, such as figure 1 As shown, it includes a U-shaped rubber waterstop 1-1 with two wings 1-1, the U-shaped part 1-2 of the U-shaped rubber waterstop 1 is filled in the structural joint 2, and the U-shaped rubber waterstop The two wing edges 1-1 of the belt 1 are set on two adjacent groove body sections 3 respectively. The two slot body sections 3 on the left and right sides of the structural joint 2 are provided with relative notches, the bottom surface of the notch is provided with embedded bolts 4, and the two wing edges 1-1 are provided with holes matching the embedded bolts 4. In the fixing hole, the wing edge 1-1 of the U-shaped rubber waterstop 1 is plugged and matched with the embedded bolt 4 .

[0028] A waterstop pressure plate 5 is arranged above the wing edge 1-1, and a bolt hole matching the fixing hole is opened on the waterstop pressure plate 5, and the waterstop pressur...

Embodiment 2

[0030] Embodiment 2, a leakage repair structure of the structural seam of the water conveyance aqueduct, the application range of the epoxy structural glue 7 is 2-3cm away from the U-shaped part 1-2 of the U-shaped rubber waterstop 1 filled in the structural seam 2 A certain area reserved by the epoxy structural adhesive 7 can be used as a protective functional area, which can prolong the service life of the U-shaped rubber waterstop 1.

[0031] Other structures of this embodiment are the same as those of Embodiment 1.

Embodiment 3

[0032] Embodiment 3, a structure for repairing leaks in the structural joints of an aqueduct, wherein the waterstop pressure plate 5 is a plane plate or an angle plate, and the bolt holes are set on the plane plate or the long side flange of the angle plate. The processing and installation of the flat plate is convenient and easy to use. The angle plate can not only achieve the effect of pressing and fixing, but also can avoid horizontal movement after filling with epoxy mortar 10.

[0033] Other structures of this embodiment are the same as Embodiment 1 or 2.

Abstract

The invention discloses a repairing structure for leakage of structural joints of water conveyance aqueducts and a repairing method thereof. The technical problem that the effect of repairing the leakage of the structure joints of the water conveyance aqueducts in the prior art is poor, so that the structure joints of the water conveyance aqueducts are prone to being damaged again is solved. The structure for repairing the leakage of the structural joints of the water conveyance aqueducts comprises a U-shaped rubber water-stop belt, two winged edges of the U-shaped rubber water-stop belt are correspondingly erected on two adjacent aqueduct body sections, and the two aqueduct body sections are provided with pre-embedded bolts; and a water-stop belt pressure plate is arranged above the U-shaped rubber water-stop belt, and the U-shaped part of the U-shaped rubber water-stop belt is filled with bitumastic oakum, and positions located between the winged edges and the bottom face of a notchand the side wall are filled with epoxy structural adhesive, the upper part of the U-shaped part is sequentially filled with a polyethylene foam board and a polysulfide sealant, and positions locatedbetween the polyethylene foam board and the polysulfide sealant and the side wall of the notch is filled with epoxy mortar. According to the structure for repairing the leakage of the structural joints of the water conveyance aqueducts and the repairing method thereof, the water-stop belt is conveniently replaced, a two-sided four-line compression technology is adopted, and the U-shaped rubber water-stop belt is enabled to be closely combined with the concrete structure of the aqueduct body sections.

Description

technical field [0001] The invention relates to the technical field of repairing water aqueducts, in particular to a structure for repairing leaks in structural seams of a water aqueduct and a repair method thereof. Background technique [0002] Aqueducts, also known as viaducts and water delivery bridges, are a group of overhead water tanks composed of bridges, tunnels or ditches that span rivers, valleys, depressions and roads. An aqueduct is a water delivery system, also used for flood discharge, sand discharge, etc. Large aqueducts can also be navigable. Aqueducts are usually erected on valleys, depressions, and rivers for water, passage, and navigation, and are used to lead distant water to towns and villages with insufficient water for drinking and irrigation. [0003] Aqueducts are mainly built with materials such as masonry, concrete and reinforced concrete. The aqueduct consists of an inlet and outlet section, a tank body, a supporting structure and a foundation. ...
