        通風管道伸縮節分類及使用要求

        來源:http://www.rps-infinia.com 日期:2022-08-23 發布人:jntfgd

        通風管道伸縮節技術是一種管道非開挖局部套環修理方法。該技術采用的主要材料為環狀橡膠止水密封帶與不銹通風管道伸縮節,在管道接口或局部損壞部位安裝橡膠圈雙脹環,通風管道伸縮節就位后用2~3 道通風管道伸縮節固定,達到止水目的。通風管道伸縮節施工速度快,質量穩定性較好,可承受接口錯位,止水套環的抗內壓效果比抗外壓要好,但對水流形態和過水斷面有影響在排水管道非開挖中,通常與鉆孔注漿法聯合使用。通風管道伸縮節主要用來大口徑管道(管徑不小于800MM)接口處漏水,大致流程:根據管道的內徑,首先在工廠定制不銹鋼壓條和橡膠條,然后進入管道安裝,先手工固定橡膠條,接著通過管道,用密封膠圈壓住通風管道伸縮節,從而完成管道局部防滲,必要時還可以對管道滲漏處進行注漿處理。
        The expansion joint technology of ventilation pipeline is a non excavation local collar repair method. The main materials used in this technology are annular rubber water stop sealing belt and stainless ventilation pipe expansion joint. Rubber ring double expansion ring is installed at the pipe interface or local damaged part. After the ventilation pipe expansion joint is in place, it is fixed with 2-3 ventilation pipe expansion joints to achieve water stop. The expansion joint of the ventilation pipeline has fast construction speed, good quality stability, and can withstand interface dislocation. The anti internal pressure effect of the water stop collar is better than that of the external pressure, but it has an impact on the water flow pattern and the cross-section. In the non excavation of the drainage pipeline, it is usually used in combination with the drilling grouting method. The expansion joint of the ventilation pipe is mainly used for water leakage at the interface of the large-diameter pipe (the pipe diameter is not less than 800mm). The general process is as follows: according to the inner diameter of the pipe, first customize the stainless steel strip and rubber strip in the factory, and then enter the pipe for installation. First fix the rubber strip manually, and then press the expansion joint of the ventilation pipe with the sealing rubber ring through the pipe, so as to complete the local anti-seepage of the pipe. If necessary, grouting can be carried out for the leakage of the pipe.

        安裝流程
        Installation process
        1.確定需要安裝通風管道伸縮節管段,在待管段上下游各一個檢查井內放置通風管道伸縮節保證待管段內臨時斷水;
        1. It is determined that it is necessary to install the expansion joint of the ventilation pipe. The expansion joint of the ventilation pipe shall be placed in the inspection shaft at the upstream and downstream of the pipe section to ensure that the water supply in the pipe section to be temporarily cut off;
        2.將管道內清洗干凈;
        2. Clean the pipeline;
        3.由于管徑DN800由工作人員直接進入管道確定位置;
        3. Since the pipe diameter is DN800, the staff directly enter the pipeline to determine the position;
        4.準備好通風管道伸縮節材料,先將環狀橡膠內襯于管道表面,再將通風管道伸縮節緊貼環狀橡膠使其固定管道表面工序結束后,確認漏水點全部止水;
        4. Prepare the materials of the expansion joint of the ventilation pipe. First, put the annular rubber lining on the pipe surface, and then close the expansion joint of the ventilation pipe to the annular rubber to fix it on the pipe surface. After the process is completed, confirm that all the water leakage points are sealed;
        5.TV內窺檢測(或人工拍照),確定管段后,是否已,作下記錄;
        5. TV endoscope inspection (or manual photo taking) to determine whether the pipe section has been recorded;
        6.路面恢復;
        6. Pavement recovery;

        7.整理竣工資料,備案。
        7. Sort out the completion data and put it on record.
        通風管道伸縮節使用要求:
        Requirements for use of expansion joints of ventilation pipes:
        (1)通風管道伸縮節設,首先要確定原管道的管道直徑,確保通風管道伸縮節外徑被管道的內徑之間的修正關系。
        (1) When designing the expansion joint of the ventilation pipe, the pipe diameter of the original pipe shall be determined first to ensure the correction relationship between the outer diameter of the expansion joint of the ventilation pipe and the inner diameter of the pipe.
        (2)采用通風管道伸縮節局部內襯法施工時,通風管道伸縮節的設計制作寬度滿足管段處的長度。
        (2) When the local lining method of ventilation pipe expansion joint is adopted for construction, the design and fabrication width of ventilation pipe expansion joint shall meet the length of the pipe section.
        (3)通風管道伸縮節與舊管道一起組成復合管道使用,內襯管設計壁厚滿足舊管道損壞地下水的滲漏壓力要求。
        (3) The expansion joint of the ventilation pipe is used together with the old pipe to form a composite pipe. The design wall thickness of the inner liner pipe meets the leakage pressure requirements of the old pipe to damage the groundwater.
