Dam structure with pouring type asphalt concrete core wall and construction method
The invention belongs to the technical field of water conservancy and hydropower engineering construction, and particularly relates to a dam structure with a pouring type asphalt concrete core wall and a construction method. The dam structure is organically composed of an asphalt concrete core wall, an asphalt macadam mixture extrusion side wall, a steel-plastic geogrid, a transition layer and a dam filling material. The construction method comprises the following steps: constructing and paying off, paving a steel-plastic geogrid, preparing an asphalt macadam mixture, constructing an extrusion side wall, erecting an adjustable bracket template, paving a transition layer and a dam filling material, disassembling the adjustable bracket template and pouring an asphalt concrete core wall to finish one-layer pouring, and repeating the steps until the construction of the asphalt concrete core wall structure is finished. The problem of inconsistent settlement of the asphalt core wall and the dam shell material is solved. The extrusion side wall construction technology is mature in face dam and rock-fill dam construction, mechanical construction is facilitated, and compared with a construction method of repeatedly moving a formwork and filling formwork gaps, the construction speed is higher, and efficiency is higher.
本发明属于水利水电工程建设技术领域，具体涉及一种带有浇筑式沥青混凝土心墙的大坝结构及施工方法。本发明的大坝结构由沥青混凝土心墙、沥青碎石混合料挤压边墙、钢塑土工格栅、过渡层和大坝填筑料有机构成。本发明通过施工放线、铺筑钢塑土工格栅、沥青碎石混合料制备及挤压边墙施工、搭设可调式支架模版、铺筑过渡层与大坝填筑料、拆卸可调式支架模版和浇筑沥青混凝土心墙完成一层浇筑，重复上述步骤，直至沥青混凝土心墙结构施工完成。本发明解决了沥青心墙与坝壳料沉降不一致的问题。本发明中设置的挤压边墙施工工艺，在面坝堆石坝施工中较为成熟，便于机械化施工，与反复移动模版并填充模版缝隙的施工方法相比，施工速度更快，效率更高。
