Description

Technical Field

[0001] The present application relates to the technical field of shield tail seal monitoring of shield machines, and more specifically, to a device for measuring parameters in an integrally pre-buried shield tail seal grease cavity. Background Art

[0002] In recent years, due to its safety and high efficiency, shield construction has become the main construction method in urban underground tunnel projects such as urban subways, municipal pipe corridors, water conservancy and hydropower. This construction method supports the front and upper soil through the shield shell of the shield machine, and adopts a variety of sealing measures to prevent the water and soil outside the shield shell from invading the shield body, thereby reliably ensuring the safety of construction personnel in the tunnel. Among them, the sealing structure of the shield machine is mainly reflected in three positions, namely the main seal of the front shield, the hinged seal of the front middle shield, and the shield tail seal between the tail shield and the pipe segment, which are all core safety components in shield construction. For the shield tail seal, damage is more common due to the particularity of the installation position of the tail shield. Damage and failure of the shield tail seal may cause water leakage at the shield tail, leakage of back filling, etc., which may seriously affect the progress of shield excavation and even cause safety accidents such as ground sedimentation. Therefore, the effectiveness of the shield tail seal is an important guarantee for the smooth excavation of the shield.

[0003] At present, the monitoring method of the shield tail sealing effect is relatively simple. The injection grease flow in the shield tail grease cavity is only measured by setting a total counter at the pump port, and the injection grease pressure in the cavity is generally monitored in the grease system loop near the shield tail outlet. However, the parameters obtained by this monitoring method can only indirectly judge the situation of the shield tail seal injection circuit, such as blockage, etc., and cannot truly feedback the actual pressure and sealing effect in the shield tail seal cavity grease cavity, and cannot meet the monitoring needs of the parameters in the grease cavity.

[0004] Therefore, how to provide an integrally embedded shield tail sealing grease cavity parameter measurement device that can directly obtain the real grease parameters in the shield tail sealing grease cavity, feedback the real sealing effect, and ensure the smooth progress of shield construction has become a technical problem that needs to be urgently solved by technical personnel in this field.
