Embodiment Construction
[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0024] refer to figure 1 , the present invention provides a device for preventing the shield machine from bouncing and its use method. By pre-embedding a steel ring at the door at the inner wall corresponding to the bottom position of the shield machine, the support is fixed and installed, and then the inclined surface of the support A water stop is set on the top, so that the part of the shield machine that extends into the door can be erected on the support to prevent the shield machine from falling. In addition, the water stop can prevent the water in the door from flowing out and play a waterproof role. It solves the problem that the shield machine is easy to fall in the initial stage, prevents the shield machine from falling, makes the shield machine always on the design axis, and ensures the construction quality. The device has a simple s...

The invention relates to a device for preventing a shield machine from heading downwards and a using method of the device. The device is applied to an initial tunnel entering stage of the shield machine, and a tunnel door is excavated in a corresponding excavation surface of the shield machine, andan embedded steel ring is installed on the inner wall of thetunnel door. The device comprises a supporting part and awater stopping part, wherein the supporting part is installed at the position,corresponding to the inner wall of the bottom of the shield machine, of the embedded steel ring, the height of thesupporting part is less than or equal to the difference between the radius of the supporting part steel ring and the radius of the shield machine, andan downwards inclining inclined surfaceisformed at the position,close to an opening of the tunnel door, of the supporting part; and the water stopping part is fixed to the opening of thetunnel door, the water stopping part is attached to theinclined surface, and theinitial end of theshield machine is enabled to enter the tunnel door by pushing the shield machine into the opening of thetunnel door, and thesupporting partsupports the bottom of the shield machine, so that the shield machine isprevented from heading downwards. The problem that the shield machine is prone to heading downwards at the initial stage iseffectively solved, the shield machine isprevented from heading downwards, so that the shield machine is always located on a designed axis, the construction quality is ensured, and the device issimple in structure, easy toimplement and low in cost.
Description
technical field [0001] The invention relates to the field of building construction, in particular to a device for preventing head-slipping of a shield machine and a method for using the same. Background technique [0002] During the initial entry process of the shield machine, in order to facilitate the entry of the shield machine, the diameter of the opening door is generally larger than the diameter of the shield machine. The launch frame, by adjusting the height of the launch frame, the shield machine placed on the launch frame can be located on the design axis. However, since the diameter of the opening is larger than the diameter of the shield machine, when the shield machine is on the axis, the shield There is a large gap between the side wall of the tunneling machine and the inner wall of the tunnel door, generally about 150mm. After the shield machine enters the tunnel door, it is easy to cause the shield machine to fall due to the center of gravity shift and other r...
