| Abstract (English): |
According to the current situation of urban underground space development, combined with the construction of super deep underground diaphragm wall of Binjiang Station on Metro Line 13 in the Phase II project of Nanjing Jiangbei New Area underground space project, this paper studied the method of lapping joint of new and old underground diaphragm wall, and carried out the scheme design according to T and I type joints respectively. Through the full rotary drilling pilot hole and cutting the protection layer of the existing underground diaphragm wall, the bonding effect of the new and old underground diaphragm wall lap surface was improved. Moreover, the method of plain wall maintenance was adopted for joint sealing, and the key technology for the joint lapping construction of new and old underground diaphragm wall and the anti-leakage treatment technology for the joints were formed. The quality of joint construction met the requirements of design and specification after field application and ultrasonic monitoring, which provided solvable experience for similar projects in the future.
