Abstract
The invention relates to a construction method for full cross-section traversing of a glass fiber-reinforced polymer underground diaphragm wall through a shield. The construction method comprises the following steps that shield equipment capable of achieving full cross-section traversing of stumbling blocks is designed and manufactured; a comprehensive and real-time monitoring network is arranged; anti-collapse pretreatment is conducted; and a traversing section construction method is conducted, specifically, by combining shield equipment performance and implementation of an anti-collapse pretreatment measure, construction parameters of glass fiber-reinforced polymer underground diaphragm wall traversing are set up, the construction parameters are finely adjusted according to station structure deformation conditions in the traversing process, and thus the purpose of quick and weak-perturbation traversing is achieved. According to the construction equipment and the construction method for full cross-section traversing of the glass fiber-reinforced polymer underground diaphragm wall through the shield, under the premise that weak perturbation on surrounding environments is ensured, through full cross-section traversing of the glass fiber-reinforced polymer underground diaphragm wall, the construction problem of full cross-section traversing of the glass fiber-reinforced polymer underground diaphragm wall through the shield under a high environment protection demand is solved.
Description
technical field [0001] The invention relates to a construction method capable of passing through an underground diaphragm wall with glass fiber reinforcement in full section while ensuring micro-disturbance of surrounding buildings (structures). Background technique [0002] With the continuous improvement of the urban subway network, it is becoming more and more important to make reasonable and full use of underground space. Especially with the gradual formation of the subway network, the construction of transfer nodes between various lines will make some subway tunnels built later have to pass through the envelope of existing subway tunnels or other underground structures in full section, which will hinder the smooth implementation of the project. How to ensure the smooth passage of the shield through the enclosure structure and ensure the safe and normal use of the existing underground structures is a very important issue in construction. [0003] In cities with relative...
