7月9日，佛山地铁3203-1标荔～伦区间右线隧道顺利贯通。
荔伦区间右线全长1355.795米，隧道穿越淤泥质土、淤泥质粉细砂、淤泥质中粗砂、粉质黏土、粉细砂、中粗砂等，区间地层较软，稍有不慎就会发生隧道整体下沉，施工风险较高。此外，右线盾构两次穿越羊大河、侧穿荔村英联综合楼及二期扩建工程、荔村商业楼及民房、爱莲桥、幼儿园、105国道公路桥等建构筑物。
为了保证盾构机安全穿过，项目部成立党员先锋队和青年突击队，全体党员和青年突击队员身先士卒、稳扎稳打，现场安全员轮班巡检，设立洞内注浆加固班，对下穿建筑基础采用袖阀管注浆加固、设置双排微型钢管桩进行隔离加固等措施，多措并举保证施工质量和安全，确保了盾构顺利接收。
