High and steep slope slab staggering soil retaining type bridge abutment and construction method
The invention discloses a high and steep slope slab staggering soil retaining type abutment and a construction method, a traditional abutment arrangement mode is abandoned, a novel high and steep slope slab staggering soil retaining type abutment structure mode is adopted, and the high and steep slope slab staggering soil retaining type abutment comprises a side face retaining wall system, a front face retaining wall system, a side face foundation slab staggering system, a front face foundation slab staggering system, a slab staggering connecting system and an abutment rear bridge road connecting system. Road engineering construction is limited by high and steep slopes in complex and hard mountainous areas, for example, the road engineering construction is arranged according to a conventional bridge abutment mode, the excavation depth of a foundation or a bearing platform foundation pit is large, large-range excavation easily causes ecological damage and water and soil loss, for example, measures are taken to protect excavation, so that adverse factors such as great increase of investment and lengthening of a construction period are caused, and then normal development of a project is influenced. The staggered platform soil retaining type bridge abutment structure is adopted, foundation or bearing platform staggered platform treatment is fully utilized to conform to terrain changes, in this way, the excavation depth of a foundation pit can be effectively reduced, ecological damage and water and soil loss are reduced, the investment cost is saved to the maximum degree, and the construction difficulty and the construction period are reduced.
本发明公开了一种高陡边坡错台挡土式桥台及施工方法，摒弃了传统桥台设置方式，采用高陡边坡新型错台挡土式桥台结构方式，包括侧面挡墙体系、正面挡墙体系、侧面基础错台体系、正面基础错台体系、错台连接体系、台后桥路连接体系。道路工程建设受复杂艰险山区高陡边坡等限制，如按常规桥台方式设置，基础或承台基坑开挖深度较深，大范围开挖易造成生态破环及水土流失，如采取措施防护开挖，将造成投资大幅增加、施工周期加长等不利因素，进而影响项目正常开展，本发明采用错台挡土式桥台结构，充分利用基础或承台错台处理顺应地势变化，这样可有效减小基坑开挖深度，降低生态破环及水土流失，最大程度节约投资成本、减小施工难度及工期。
