Construction method for comprehensive treatment of urban riverway crossing underneath railway
The invention discloses a construction method for comprehensive treatment of an urban riverway crossing underneath a railway. The construction method comprises the following steps: (1) upstream and downstream flow guiding grooves are constructed, specifically, water bodies discharged in a scattered mode in the riverway are collected together at the position at a distance of 40 m from the upstreamof a cast-in-place beam support and then flow into the downstream through the flow guiding grooves according to designated routes; (2) a water dropping step is constructed, specifically, the water dropping step is additionally arranged at the position at a distance of 20 m from the upstream of the cast-in-place beam support, a brick-set wall is adopted as the water dropping step, the thickness ofthe wall is 50 cm, and the water dropping height difference is 1 m; (3) treatment of a cast-in-place beam support base and backfilling construction of a bearing platform are conducted; (4) rectangularquadrate culverts are constructed; (5) cushion layer pouring construction of a cast-in-place beam support system is conducted; and (6) side drainage systems of the downstream of the support are constructed. According to the construction method, not only is the construction safety of the cast-in-place beam support is ensured, but also the construction period is ensured, meanwhile the constructioncost is lowered greatly, and the great effect is achieved.
本发明公开了一种城市河道下穿铁路综合治理施工方法，包括如下步骤：（1）、上下游导流槽施工：在距现浇梁支架上游40m的位置把河道内零散排的水体汇集起来，然后通过导流槽按指定的路劲流入下游；（2）、滴水台阶施工：在距现浇梁支架上游20m处增加滴水台阶，滴水台阶采用砖砌墙体，墙体厚度为50cm，滴水高差为1m；（3）、现浇梁支架基底处理及承台回填施工；（4）、矩形方涵施工；（5）、现浇梁支架体系垫层浇筑施工；（6）、支架下游侧排水系统施工。本发明方法既保证了现浇梁支架施工的安全，也保证了工期，同时大大降低了施工成本，取得了很好的效果。
