充分考虑现行国家规范规定的砖砌排水沟管线的间距
1、砖砌排水沟施工方案第一步：排水沟的定位：根据地下相关的构筑物，弄清管线和设计图纸实际情况，对砖砌排水沟充分研究分析，进行合理布局，充分考虑现行国家规范规定的砖砌排水沟管线的间距要求，现有建筑物、构筑物进出口管线的坐标、标高和确定堆料、堆土、运料的区间和位置。
1. The first step of the construction scheme of the brick drainage ditch: the positioning of the drainage ditch: according to the underground related structures, make clear the actual situation of the pipeline and the design drawings, fully study and analyze the brick drainage ditch, make a reasonable layout, fully consider the spacing requirements of the brick drainage ditch pipeline specified in the current national specifications, the coordinates, elevation and determination of the pile of the existing buildings and structures' inlet and outlet pipelines The range and location of materials, stacking and transportation.
2、砖砌排水沟施工方案之沟槽开挖 2.1槽底开挖宽度等于排水沟结构基础宽度加两侧工作面宽度，每侧工作面宽度应不小于300mm。用机械开槽或开挖沟槽后，当天不能进行下一道工序作业时，沟底应留出200mm左右的一层土不挖，待下道工序前用人工清底。
2. Trench excavation in the construction scheme of brick drainage ditch 2.1 the excavation width of trench bottom is equal to the foundation width of drainage ditch structure plus the width of working faces on both sides, and the width of working faces on each side shall not be less than 300 mm. After mechanical trenching or trench excavation, if the next process cannot be carried out on the same day, a layer of soil around 200mm shall be left at the bottom of the trench without excavation, and the bottom shall be cleared manually before the next process.
3、基底处理 ，地基处理应按设计规定进行，施工中遇到与设计不符的松软地基及杂土层等情况，就要跟设计人员协商沟通。
3. Foundation treatment and foundation treatment shall be carried out in accordance with the design regulations. In case of soft foundation and miscellaneous soil layer inconsistent with the design during construction, it is necessary to consult and communicate with the designer.
