排水系统有三种要素必须增强

发布时间:2013/5/17

有三种要素必须增强:认知、情感、行动。
There are three elements: cognitive, affective, must enhance the action.
塑料盲沟厂家介绍,渗管一般用钢管、铸铁管或钢筋混凝土、混凝土等做成孔管,管径、壁厚、开孔数目以及周围填料经计算确定。可防止浸润线由坝坡逸出。渗管或盲沟与坝轴平行布置厂,坡向两侧或中间的集水管,坡度由不淤流速确定,一般为1%左右。山坡、林园等均采用这种型式,塑料盲沟利用原排水系统作后期坝排渗的集水井、管,效果很好。
The plastic blind drain pipe manufacturers, permeability generally used steel pipe, cast iron pipe or reinforced concrete, concrete made of pipe, pipe diameter, wall thickness, number of holes and the surrounding filler was determined. To prevent infiltration line by the dam slope escape. Infiltration tube or blind ditch and dam axis parallel layout of factory, the slope to the water collecting pipe on both sides or in the middle of the slope, determined by the velocity of deposition, generally about 1%. Hill, Lin Yuan used this type, plastic blind ditch drainage system using the original later dam drainage collector well, pipe, the effect is very good.
排渗盲沟一般用块石做成,周围填以砾石,砂做反滤层。此外还可使用无砂混凝土管做渗管,因其强度较低,适于浅层敷设。欲提高其强度可做成有无砂混凝土滤水孔的混凝土管。无砂混凝土配比一般为1:4(水泥:砾石),砾石粒径采用2~10毫米。从而加速了软弱土地基的沉降过程,使地基得到压密加固。
Drainage ditch into general use stone, around filled with gravel, sand filter. Also can use of no-fines concrete pipe seepage tube, due to its low strength, suitable for shallow laying. To improve its strength can be made into a concrete without sand filter water holes in concrete pipe. No sand concrete ratio is generally 1:4 (cement: Gravel), gravel size by 2 to 10 mm. To speed up the process of settlement of soft soil foundation, the foundation is consolidated reinforcement.
