Asphalt concrete core wall dam and construction method
The invention discloses an asphalt concrete core wall dam and a construction method. The asphalt concrete core wall dam comprises an upstream side rolling dam body, an upstream side concrete extrusion side wall, two-cloth one-membrane geotechnical cloth, an asphalt concrete core wall, a downstream side concrete extrusion side wall and a downstream side rolling dam body which are sequentially arranged from upstream to downstream. Concrete bases are arranged at the bottoms of the upstream side concrete extrusion side wall, the two-cloth one-membrane geotechnical cloth, the asphalt concrete core wall and the downstream side concrete extrusion side wall, and copper sheet water stops are arranged between the concrete bases and the asphalt concrete core wall. Traditional core wall transition material construction is eliminated, the parts, close to the extrusion side wall, of the upstream and the downstream are compacted through rolling under the supporting effect of the extrusion side wall, the extrusion side wall bears certain water pressure, the stress of asphalt concrete is reduced, the large stress effect between the asphalt concrete core wall and the concrete base is prevented, and the side wall and the two-cloth and one-membrane geotechnical cloth are extruded by using the upstream side concrete, so that the anti-seepage performance of the dam body is improved.
本发明公开了一种沥青混凝土心墙坝及施工方法，包括从上游到下游依次设置的上游侧碾压坝体、上游侧混凝土挤压边墙、二布一膜土工布、沥青混凝土心墙、下游侧混凝土挤压边墙、下游侧碾压坝体，在上游侧混凝土挤压边墙、二布一膜土工布、沥青混凝土心墙和下游侧混凝土挤压边墙的底部设置混凝土基座，在混凝土基座和沥青混凝土心墙中间设置铜片止水。本发明取消传统心墙过渡料施工，利用挤压边墙支撑作用，使上下游靠近挤压边墙部位碾压得密实，并利用挤压边墙承受一定的水压力，减少沥青混凝土受力，防止沥青混凝土心墙与混凝土基座之间受到大的应力作用，并利用上游侧混凝土挤压边墙、二布一膜土工布，增加坝体防渗性能。
