Problems solved by technology

This kind of water-stop structure squeezes the closed cells through the convex-concave compression structure between the upper plate and the lower plate. The foam board and the water-stop are often not compacted or the fit is not good after pressing, which may directly cause water seepage.

Embodiment 1

[0040] refer to figure 1 and figure 2 , is an aqueduct water-stop structure disclosed in the present invention, comprising an aqueduct body 1, a structural joint 2, a water-stop member 3, a water-stop steel plate 4, and a sealing layer 5. The aqueduct body 1 is formed by pouring reinforced concrete, and the adjacent aqueduct body 1 Structural seams 2 are arranged between them. When pouring the aqueduct body 1, a groove 11 is reserved at the top of the aqueduct body 1 at the structural seams 2. The groove 11 is provided with a water-stop steel plate 4 and a water-stop piece 3 that is connected to the water-stop steel plate 4 and covers the structural joint 2. When the aqueduct body 1 is poured, one end of the water-stop steel plate 4 is inserted into the aqueduct body 1 and welded and fixed with steel bars. , the other end protrudes from the aqueduct body 1 and is connected with the water stop member 3 . The sealing layer 5 is arranged on the upper part of the waterstop 3 an...

Embodiment 2

[0048] refer to figure 1 and figure 2 , a kind of aqueduct water-stop structure construction method, comprises the following steps:

[0049] S1. When pouring the aqueduct body 1, use the total station to set out the setting position of the water-stop steel plate 4, and pre-embed the water-stop steel plate 4 in the aqueduct body 1, and weld the water-stop steel plate 4 to the reinforcement inside the aqueduct body 1 Fix, and reserve a groove 11 at the structural joint 2 of the aqueduct body 1, and then pour the aqueduct body 1.

[0050] S2. Adhesively fix the polyethylene caulking board 6 on the depression of the water stop member 3, and then install the water stop member 3.

[0051] S3. Apply a layer of epoxy structural glue 8 on the bottom of the groove 11, install the water stop 3 in the groove 11, and fix the flange plate 32 in the groove 11 with expansion bolts, and install the water stop 3 , apply sealant 7 on the waterproof steel plate 4, and insert it into the slot ...

Abstract

The invention relates to an aqueduct water-stop structure, which includes an aqueduct body and a structural seam arranged on the aqueduct body, a groove is opened at the structural seam on the top of the aqueduct body, and a stopper arranged in the groove to cover the structural seam The water fittings, the water-stop steel plate set in the groove and connected with the water-stop piece, and the sealing layer set on the top of the water-stop piece and filling the groove, one end of the water-stop steel plate is inserted into the aqueduct body, and the other end extends out of the aqueduct body; The waterstop includes an inverted U-shaped waterstop located directly above the structural seam and a flange plate arranged on both wings of the waterstop and fitted and fixed at the bottom of the groove. The flange plate is folded upward to form a card slot. The water-stop steel plate is inserted into the slot. The invention has the advantages of good sealing effect, water seepage prevention and adaptation to the deformation of the aqueduct body.

Description

technical field [0001] The invention relates to the technical field of aqueduct construction, in particular to an aqueduct water-stop structure and a construction method thereof. Background technique [0002] An aqueduct is an overhead water delivery structure that transports channel water across river canals, roads, mountain rushes, valley mouths, etc. It is one of the most widely used intersecting buildings in canal systems. In addition to water, industrial water, and cross-basin water transfer, it can also be used for drainage and diversion. [0003] At present, the water stop structure in the aqueduct is an important detail structure, the design and construction are difficult, and the failure rate is high. The water stop structure determines the success or failure of the aqueduct project. The water-stop structures of aqueduct engineering mainly include mid-buried type, bonded type and pressure plate type, but there are the following problems: [0004] In the buried wat...
