混凝土生态护坡施工要点
Key Points of Concrete Ecological Slope Protection Construction
1.按照测量放好的线,根据设计坡比,进行削坡及整平坡面;
1. According to the measured line and the design slope ratio, the slope is cut and leveled.

2.按设计高程、宽度和深度,开挖压顶、坡脚槽、匡格槽。机械开挖时的应预留 10cm 由人工开挖,多余土方运出指定位置;
2. According to the design elevation, width and depth, excavate
roof pressing, foot groove and rectangular groove. In mechanical
excavation, 10 cm should be reserved for manual excavation, and excess
earthwork should be transported out of the designated location.

3.在开挖过程中,经常测量校核开挖平面位置、标高、控制桩号、边坡坡度等是否符合设计图纸要求;
3. In the process of excavation, it is often measured and checked
whether the excavation plane position, elevation, control pile number
and slope meet the requirements of design drawings.
4.浇筑框格砼时,应注意防止混凝土的分层离析,在斜坡上浇筑混凝土应采用斜槽、溜管等下料;
4. When pouring frame concrete, attention should be paid to
preventing the stratification and segregation of concrete, and the
concrete pouring on slopes should adopt the cutting materials such as
chutes and chutes.

5.土工布剪裁整齐,尺寸应准确,缝合的宽度一般为 0.1m 以上,搭接宽度一般为 0.2m 以上;
5. Geotextile should be trimmed neatly and its size should be
accurate. The width of stitching is generally more than 0.1 m, and the
lap width is generally more than 0.2 M.
6.土工布在斜坡上搭接时,尽量减少横向接缝,将高处的土工布搭接在低处的土工布上,施工中严禁接头错动;
6. When overlapping geotextiles on slopes, minimize transverse
joints and overlap geotextiles at high places with geotextiles at low
places. Joint dislocation is strictly prohibited in construction.
