Problems solved by technology

[0002] Concrete face rockfill dams are developing very rapidly in earth-rockfill dams. The traditional construction technology of copper waterstop, one of the anti-seepage systems of face rockfill dams, is to use special equipment (jack calender) to cold-press about 25m to 30m at a time. Then weld in place one by one, time-consuming, labor-intensive and material-intensive
Conventional copper waterstop construction technology has slow construction speed, high cost and many welded joints, making quality control difficult

Embodiment Construction

[0037] Such as Figure 1 to Figure 4 The construction method of the copper waterstop in the anti-seepage system of a concrete face rockfill dam shown includes the following steps:

[0038] Step 1, hoisting the copper waterstop calender 2 on the bracket 5;

[0039] Step 2, integrally hoisting the copper waterstop calender 2 and the bracket 5 at the vertical joint position of the concrete face rockfill dam 1 crest (such as figure 2 shown);

[0040] Step 3, hoisting the reel 4 wrapped with the copper sheet raw material 3 on the reel support 5-1 of the bracket 5;

[0041] Step 4, continuous cold-pressed copper waterstop 6: open the copper waterstop calender 2, send the copper skin raw material 3 on the reel 4 into the copper waterstop calender 2, and pass through the copper waterstop The calender 2 continuously cold-presses the copper skin raw material 3 into a copper waterstop 6, the copper waterstop 6 includes a bottom plate 6-1, and both sides of the bottom plate 6-1 are li...

Abstract

The invention discloses a construction method of a copper water-stop in a seepage-proofing system of a concrete face rockfill dam. The construction method comprises the following steps: step (1) hoisting a copper water-stop calendar on a bracket; step (2) integrally hoisting the copper water-stop calendar and the bracket at the position of a vertical seam of the top of the concrete face rockfill dam; step (3) hoisting a coiling block which is intertwined with a copper sheet raw material on a coiling block bracket of the bracket; step (4) performing continuous cold rolling on the copper water-stop; step (5) filing flexible fillers. The construction method can be used for preparing a long copper water-stop extending from the top of the concrete face rockfill dam to the bottom of the dam by cold rolling, so that the long copper water-stop needs not to be formed by welding a plurality of segments of copper water-stops; therefore, installation weld joints of the copper water-stop are reduced, and the quality of the copper water-stop is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of construction of an anti-seepage system of a concrete face rockfill dam, and in particular relates to a construction method of a copper waterstop in the anti-seepage system of a concrete face rockfill dam. Background technique [0002] Concrete face rockfill dams are developing very rapidly in earth-rockfill dams. The traditional construction technology of copper waterstop, one of the anti-seepage systems of face rockfill dams, is to use special equipment (jack calender) to cold-press about 25m to 30m at a time. Then weld in place one by one, which is time-consuming, labor-intensive and material-consuming. Conventional copper waterstop construction technology has the disadvantages of slow construction speed, high cost and many welded joints, making quality control difficult. How to design a method that can quickly and efficiently complete the construction of copper waterstops in the anti-seepage system of...
