Abstract

The invention provides a pLugging device for a shieLd tunneL. After the pLugging device carries out pLugging, a sensor in the pLugging device detects a Leakage point, the Leakage point is repaired intime, and therefore the seaLing effect of the pLugging device on the shieLd tunneL is improved. According to the pLugging device, the Leakage point can be searched for, compensation is carried out intime aiming at the Leakage point, the fit degree of the pLugging device and the tunneL is increased, and the pLugging effect is improved.

Description

technical field [0001] The invention relates to a blocking device, in particular to a blocking device for a shield tunnel. Background technique [0002] In the process of shield tunnel construction, there will be floods, toxic gas or smoke and other critical situations. In order to prevent the spread of floods or gas smoke, etc., inflatable devices are often used to block, but the existing blocking devices are different from those of tunnels. The degree of fit is not high enough, the sealing is not strict, and the sealing effect is poor. Moreover, the existing sealing device is large in size. Ineffective, and the existing blocking device has no targeted measures to strengthen the seal for waterproofing and gasproofing. Contents of the invention [0003] In the present invention, water-swellable rubber seals and inflatable seals are added to the inflatable expandable container body of the blocking device. The sensor in the sensor detects the leakage point, and according t...
