水泵出水管道应该满足哪些条件

date.png 2020-04-07 10:22:55

水泵出水管道明管设计时应满足那些请求?

答:明管转弯处必需设置镇墩。在明管直线段上设置的镇墩间距不宜超越100m。两镇墩之间的管道应设伸缩节,伸缩节应布置在上端;管道支墩的型式和间距应经技术剖析和经济比拟肯定。除伸缩节左近处,其他各支墩宜采用等间距布置。预应力钢筋混凝土管道应采用连续管座或每节设2个支墩;管间净距不应小于0.8m,钢管底部应高出管道槽空中0.6m,预应力钢筋混凝土管承插口底部应高出管槽空中0.3m;管槽应有排水设备。坡面宜护砌。当管槽纵向坡度较陡时,应设人行阶梯便道,其宽度不宜小于1.0m;当管径大于或等于1.0m且管道较长时,应设检查孔。每条管道设置的检查孔不宜少于2个;在严寒地域冬季运转时,可依据需求对管道采取防冻保温措施。

水泵出水管道埋管设计中应满足那些请求?

答:埋管管顶小埋深应在大冻土深度以下;埋管宜采用连续垫座。圬工垫座的包角可取90o-135o;管间净距不应小于0.8m;埋入公开的钢管应做防锈处置;当公开水对钢管有腐蚀作用时,应采取防腐蚀措施;埋管上回填土顶面应做横向及纵向排水沟;埋管应设检查孔,每条管道不宜少于2个。。

What requirements should be met in the design of pump outlet pipe?


A: anchor blocks must be set at the open pipe turning. The distance between the anchor blocks on the straight section of the exposed pipe should not exceed 100m. Expansion joint shall be set for the pipeline between two anchor blocks, and the expansion joint shall be arranged at the upper end; the type and spacing of pipe buttress shall be confirmed by technical analysis and economic comparison. In addition to the left near the expansion joint, the other buttresses should be arranged with equal spacing. The prestressed reinforced concrete pipe shall be provided with a continuous pipe seat or two buttresses at each section; the clear distance between pipes shall not be less than 0.8m, the bottom of steel pipe shall be 0.6m higher than the air of the pipe slot, the bottom of the prestressed reinforced concrete pipe socket shall be 0.3m higher than the air of the pipe slot; the pipe slot shall be provided with drainage equipment. The slope should be protected. When the longitudinal gradient of the pipe trench is steep, a pedestrian step access road shall be set up, with the width not less than 1.0m; when the pipe diameter is greater than or equal to 1.0m and the pipe is long, an inspection hole shall be set up. The number of inspection holes for each pipeline should not be less than 2; when the pipeline is operated in winter in severe cold area, anti freezing and heat preservation measures can be taken for the pipeline according to the demand.

What requirements should be met in the design of water pump outlet pipe?


Answer: the minimum buried depth of the buried pipe top should be below the maximum frozen soil depth; the continuous cushion should be used for the buried pipe. The angle of masonry cushion seat can be 90o-135o; the clear distance between pipes should not be less than 0.8m; the steel pipes buried in the open should be treated with rust prevention; when the open water has corrosive effect on the steel pipes, anti-corrosion measures should be taken; the top surface of backfill on the buried pipes should be provided with horizontal and vertical drainage ditches; the buried pipes should be provided with inspection holes, and each pipe should not be less than 2..
