Construction method of cast-in-place ballast bed embedded continuous bearing turnout
The invention relates to the technical field of rail traffic road construction, aims to solve the technical blank problem in the prior art, and provides a cast-in-place ballast bed embedded continuous supporting turnout construction method which comprises the following steps: constructing a base and marking a line center line, a turnout area contour line, a theoretical turnout center, a turnout starting point, a turnout ending point and other key point positions; installing a turnout steel tank and then finely adjusting and fixing; a ballast bed reinforcement cage is bound on the base, a ballast bed formwork is installed at the position of the turnout zone contour line, and concrete is poured; turnout steel rail pieces are laid on the cast-in-place roadbed slab and adjusted in place, and welding is completed; mounting an elastic base plate and a heightening base plate in the turnout steel tank; the turnout steel rail piece falls into the steel tank, and the geometric shape and position are adjusted and temporarily fixed; and a high-molecular elastic material is poured to lock the steel rail piece. Most of the steps of the construction method are implemented on site, the risk of transferring and hoisting long and large steel rail pieces and heavy objects such as track plates is reduced, and on-site operation is more convenient and faster.
本发明涉及轨道交通道路施工技术领域，旨在解决现有技术存在技术上空白的问题，提供一种现浇道床嵌入式连续支承道岔施工方法，包括以下步骤：施工底座并标记线路中线、道岔区轮廓线以及理论岔心、道岔起终点等关键点位置；安装道岔钢槽后精调固定；在底座上绑扎道床钢筋笼，在道岔区轮廓线位置安装道床模板并浇筑混凝土；在现浇道床板上进行道岔钢轨件铺设并调整到位完成焊接；在道岔钢槽内安装弹性垫板、调高垫板；将道岔钢轨件落入钢槽内，调整几何形位并临时固定；浇注高分子弹性材料锁固钢轨件。本发明施工方法的大部分步骤在现场实施，减小了钢轨件等长大件和轨道板等重物转运吊装的风险，现场操作更方便、快速。
