Welding and detection process used for HDPE geomembrane of refuse landfill
The invention discloses a welding and detection process used for an HDPE geomembrane of a refuse landfill. Welding equipment in the welding process comprises a double-seam welding machine, an extrusion welding machine and a hot air blower, double-seam welding is mainly adopted, for pressing sealing and seam lapping or local repairing, the extrusion welding machine is adopted for welding seam extrusion, the hot air blower is used for blowing and melting the lower portion of a lap joint part; and the detection process is mainly based on air pressure detection, vacuum detection is adopted for cooperation, the detection process is suitable for the situation of local width-based propulsion or a welding seam full detection requirement, and air pressure detection and vacuum detection are both based on the CJJ113-2007 standard. The welding and detection process comprises welding construction and detection construction processes, under the condition that full-inspection construction is needed for local welding seams or width-based propulsion is required, the effect of the welding machine can be fully achieved, extrusion welding repairing work is reduced, the welding seam detection process is simplified, the construction efficiency is improved, and the requirements for seepage prevention and long-term operation of the refuse landfill can be met.
本发明公开了一种用于垃圾填埋场HDPE土工膜的焊接及检测工艺，焊接工艺中的焊接设备包括双缝焊接机、挤压焊机和热吹风机，以双缝焊接为主，打压封口、接缝或局部修补采用挤压焊机做挤压焊缝，搭接部位下方用热吹风机吹熔；检测工艺以气压检测为主，配合真空检测，适用于局部按幅推进或要求焊缝全检的情况，气压检测与真空检测均依据CJJ113‑2007标准。本发明包括焊接施工及检测的施工工艺，在局部焊缝需全检施工或要求按幅推进的情况下，能充分发挥焊接机作用，减少挤压焊修补工作，简化焊缝检测流程，提高施工效率，能满足垃圾填埋场防渗和长期运营的需求。
