塑料管重量轻,表面光,不生锈,挠性好,能适应起伏不平的复杂地形,施工运输方便。在农田灌溉等方面广为运用,但对接时要求较严,接不好易漏水。现介绍一种安全可靠及经济实用的水煮塑料管对接法: 先找一截坚硬的木头,按塑料管的粗细做一圆锥形撑木,根部直径要稍比塑料管外径大一些,表面刨光。为了便于插入拔出,在撑木尾部钻一圆孔,穿一根φ18—20毫米的钢筋。撑插时,表面还要涂一层黄油,起润滑作用。然后,按照输水方向,先将上节塑料管口的外边齐头削成坡度,再将下节塑料管的一端
The plastic tube is light in weight, surface light, non-rusting, and flexible. It can adapt to undulating and complex terrain and is convenient for construction and transportation. It is widely used in farmland irrigation and other aspects, but the requirements for docking are strict, and water leakage is not good. Now we introduce a safe, reliable, economical and practical method for docking boiled plastic pipes: First, find a piece of hard wood, and make a conical bracing according to the thickness of the plastic pipe. The diameter of the root should be slightly larger than the outer diameter of the plastic pipe. Plane light. In order to facilitate the insertion and extraction, a round hole is drilled in the rear end of the pole, and a φ18-20 mm steel bar is worn. When inserting, the surface is also coated with a layer of butter to provide lubrication. Then, according to the direction of water flow, first trim the outer edges of the plastic nozzles of the upper section into a slope, and then put one end of the lower section plastic pipe.
