[0002] The hub is mainly composed of asphalt concrete core wall dam, right bank spillway, right bank pressure-free flood discharge and sand diversion tunnel, power generation water diversion tunnel, shore-side powerhouse behind the dam, ecological water discharge pipe and fish-passing buildings. The anti-seepage treatment project of the dam foundation is that the dam sections 0+116-0+120.45 and 0+512.45-0+517.45 are artificially dug hole trough concrete walls, and the section 0+120-0+512 is a mechanically drilled hole trough concrete anti-seepage wall. The anti-seepage structure adopts concrete anti-seepage wall and dam foundation curtain grouting. The axis length is 400.8m. The anti-seepage wall is used for anti-seepage, and the anti-seepage body material is C30W8F100 concrete. The anti-seepage wall is 1m thick, the bottom of the anti-seepage wall is 2m deep into the bedrock, and the maximum depth of the anti-seepage wall is about 58m. The total project volume is about 16,000 m2, including 15,198.4 m2 of concrete underground continuous wall (cover layer), 801.6 m2 of concrete underground continuous wall (rock layer), and the permeability coefficient of the anti-seepage wall after completion is K≤2×10 -7 cm / s.
[0003] The construction of the anti-seepage wall is divided into two phases, first constructing the phase I trough section (hole) and then constructing the phase II trough section (hole). Before pouring the phase I trough, a joint pipe is first laid, and then concrete is poured. During the concrete pouring process and within a certain period of time after the pouring is completed, the joint pipe is gradually pulled out according to the initial setting of the concrete in the trough, and a joint hole is formed at the end of the phase I trough hole. When pouring concrete in the phase II trough hole, the joint hole is close to the side wall of the phase I trough hole to form an arc-shaped joint. In order to form an effective connection between the wall sections, the joint hole needs to be brushed before pouring the phase II trough. The joint hole is brushed with a round steel wire brush with a certain weight. During the brushing process, the brush is easy to rotate in the hole, which can easily cause the hole wall to be not cleaned, which has a certain impact on the wall anti-seepage. Therefore, the present application proposes a joint brush positioning device. Summary of the invention
