摘要
随着城市化加快,电力隧道在电网建设中得到应用,采用顶管法建造的电缆隧道要求达到二级防水,电缆顶管隧道作为地下工程,其渗漏水不仅影响现场施工,还影响以后的隧道运营维护和内部设备的使用,需要对渗漏水情况予以治理。渗漏水属顶管隧道病害,需查清原因,采取合理的治理措施,根据顶管渗漏水情况,针对性地从管节密封、中继间密封和防渗漏惰性浆液等方面采取以堵为主的治理措施,根据地表监测成果,未出现预警情况,保证了工程有序进行。
With the acceleration of urbanization,power tunnels have been applied in power grid construction.The cable tunnel constructed using the top-down method requires a second level waterproofing.As an underground project,the leakage of water in cable jacking tunnels not only affects on-site construction,but also affects future tunnel operation and maintenance,as well as the use of internal equipment.Therefore,it is necessary to control the leakage situation.Leakage water belongs to the disease of top pipe tunnel,and the cause needs to be identified and reasonable treatment measures taken.Based on the leakage situation of the top pipe,this article takes targeted measures to control the leakage mainly through blockage from the aspects of pipe joint sealing,relay sealing,and anti-seepage inert slurry.According to the surface monitoring results,there were no warning situations,ensuring the orderly progress of the project.
