随着我国给水工程事业的迅速发展,管材感到供不应求。非金属管材中特别是预应力钢筋混凝土管和石棉水泥管,虽已生产不少,但仍不能满足建筑中的大量需要。因此,在一定范围内考虑采用钢丝网水泥管代替钢铁管道,是有实际意义的。我们曾对钢丝网水泥管进行了比较系统的试制和试验工作。试制的钢丝网水泥管大部分是内径400毫米、长4米的管子,配置3～8层由0.5～1.2毫米的冷拔钢丝(强度60kg/mm~2以上)编成5～15毫米方格的
With the rapid development of water supply projects in our country, the supply of pipes feels in short supply. Non-metallic pipes, especially pre-stressed reinforced concrete pipes and asbestos cement pipes, although they have been produced a lot, still can not meet the large number of needs in the building. Therefore, it is of practical significance to consider the use of wire mesh cement pipes instead of steel pipes within a certain range. We have conducted comparative trial production and testing of steel mesh cement pipes. Most of the prototype steel wire mesh cement pipes are tubes with an inner diameter of 400 mm and a length of 4 meters. They are arranged with 3 to 8 layers of 0.5 to 1.2 mm cold-drawn steel wire (strengths of 60 kg/mm~2) and are woven into 5 to 15 mm squares. of
