浅谈城市地下综合管廊伸缩缝中埋式止水带施工技术改进措施

Discussion on the Improvement Measures of the Construction Technology of Medium-Buried Waterproof Belt in the Expansion Joint of Urban Underground Pipe Gallery

城市地下综合管廊伸缩缝一旦漏水,堵漏难度非常大,目前,现有技术不能完全将其永久堵住,同一位置只要漏水一次,每年至少堵漏1~3次,从长远看,会增加管廊运营维护成本,影响管廊使用寿命。因此,管廊伸缩缝中埋式止水带施工技术改进已成为当前管廊建设者重点关注的问题,论文针对管廊伸缩缝中埋式止水带施工技术改进提出了相应措施。

Once there occurs leakage in the expansion joint of urban underground pipe gallery, it will be very difficult to plug the leakage. At present, the existing technology can not completely plug it permanently, as long as the same location leaks once, it needs to be plugged at least 1~3 times a year. In the long run, the operation and maintenance cost will be increased, and the service life of the gallery will be affected. Therefore, the improvement of the construction technology of the medium-buried waterproof belt in the expansion joint of the pipe gallery has become the focus of the current pipe gallery builders. The paper puts forward some corresponding measures to improve the construction technology of the medium-buried waterproof belt in the expansion joint of the pipe gallery.
