目前使用的管道主要有三大類。   類是金屬管,如內搪塑料的熱鍍鑄鐵管、鋼管、不銹鋼管等。   類是塑復金屬管,如塑復鋼管,鋁塑復合管等。第三類是塑料管,如PP—R(交聯聚丙烯高密度網狀工程塑料)。   

  

  管道安裝前,應根據設計圖紙要求,采用垂球或經緯儀及鋼尺,在墻面上測設出,落水管位置并彈上墨線,管線定位應避開門窗洞口。

  落水管的支架采用卡架,安裝時根據設計要求定出支架形式及支架位置,在磚墻安裝支架前應    墻洞內灰塵,澆水濕潤,將支架伸入墻上預留洞內,用水泥砂漿填塞飽滿?;炷涟迕婕盎炷翂?、梁、柱上采用膨脹螺栓固定支架。支架埋入墻內尺寸根據支架形式及管徑而定,一般埋入 150~200mm。支架要求除銹刷防銹漆。

  落水管按設計要求安裝伸縮節,設計無要求時按規范要求將伸縮節置于三通下方。立管在穿樓板處 固定,應復查頂板洞口是否合適。插入端應先畫好插入長度標記,然后用力插至標記處為止,合適后即 用 U 形抱卡緊固于伸縮節上沿。然后找正、找直,并測量頂板與三通口的距離是否符合要求。無誤后 即可堵洞,并將上層頂預留伸縮節封嚴。立管伸縮節在樓板層高不大于 4m 時,排水立管和通氣立管每 層設一伸縮節,層高大于 4m 時,其數量應根據管道設計伸縮量和伸縮節的允許伸縮量計算確定。

  室外雨水管底部根據設計要求采用散排或集中排水。若采用散排,應在下端出口處加彎頭,不得直接沖刷地面。若采用集中排水,在穿過散水時應增加穿墻套管,保證落水管與散水可以自由伸縮

There are three main types of pipes currently in use. Category is metal pipe, such as lined with plastic hot-dip cast iron pipe, steel pipe, stainless steel pipe and so on. Class is plastic-clad metal pipe, such as plastic-clad steel pipe, aluminum-plastic composite pipe and so on. The third category is plastic pipes, such as PP -- R cross-linked polypropylene high-density Mesh engineering plastics. Before the installation of the pipeline, according to the requirements of the design drawings, the vertical ball or theodolite and steel ruler should be used on the wall, the location of the downspout and the spring ink line, the positioning of the pipeline should avoid the door and window holes. The bracket of the falling water pipe adopts the clamp frame, and the bracket form and the bracket position are determined according to the design requirements during installation. Before installing the bracket in the brick wall, the dust in the wall hole should be moistened by water, and the bracket should be extended into the wall to reserve the hole, fill up with cement mortar. Expansion bolts are used to fix the bracket on the concrete slab surface, concrete wall, beam and column. The size of the bracket embedded in the wall depends on the type of bracket and the pipe diameter. Generally, 150 ~ 200mm is embedded in the wall. Brackets require rust remover brush antirust paint. The expansion joint shall be installed in the downspouts according to the design requirements. When the design is not required, the expansion joint shall be placed under the tee joint according to the specifications. Risers in the floor, fixed, should check whether the roof hole is appropriate. Insert end should first draw the length of the insert mark, and then forcibly insert until the mark, after the appropriate u-shaped hold card is fixed in the expansion joint on the top edge. Then find the right, find the straight, and measure the roof and three-way port distance is in line with the requirements. After that, the hole can be plugged, and the top of the expansion joint reserved for sealing. When the floor height of the risers is not more than 4M, there is one expansion joint for each floor of the drainage risers and ventilating risers, and when the floor height is more than 4M, the number of expansion joints shall be calculated and determined according to the design expansion amount and the allowable expansion amount of expansion joints. The bottom of the outdoor rain water pipe can be drained in a loose way or in a concentrated way according to the design requirements. If the use of scattered, should be in the lower end of the outlet elbow, not directly scouring the ground. If the use of centralized drainage, through the water should be increased through the wall casing, to ensure that the water pipe and water can be free expansion and contraction
