Abstract

The invention discloses a shield tail sealing brush structure for adding a spring plate to improve resilience force, which comprises a shell plate and a front protective plate and a rear protective plate which are arranged on the shell plate. The shield tail sealing brush structure is characterized in that at least two layers of stainless steel wire groups are fixed in the shell plate by pins; the stainless steel wire groups are arranged between the front protective plate and the rear protective plate; the spring plate is also arranged between the two layers of stainless steel wire groups; and the front protective plate, the rear protective plate and the spring plate are fixed in the shell plate by the pins. In the shield tail sealing brush structure, the spring plate is added between the two stainless steel wire groups, so the resilience force of the stainless steel wire groups is increased, the service life of the stainless steel wire groups is prolonged, shield tail sealing is prevented from losing efficacy in the using process, the construction quality and construction process are ensured, the time of repairing or replacing the shield tail sealing brush is reduced simultaneously, and the cost is reduced.

Description

[0001] technical field

[0002] The invention relates to a shield tail seal brush structure of a shield machine, in particular to a shield tail seal brush structure with spring plates added to improve resilience.

[0003] Background technique

[0004] With the development of urban construction in our country, underground rail transit, cross-river tunnels and other underground projects are increasing day by day, and the shield driving distance of tunnels is also getting longer and longer. The shield tail seal of the shield machine is generally composed of 3 shield tail seal brushes, forming two grease compartments, namely the front compartment and the rear compartment, the first two are short shield tail brushes, and the third is long shield tail brushes. During shield excavation, the segment is stationary and the shield body is moving continuously, so there is relative sliding between the shield tail and the installed segment. In order to prevent external sewage and sedimen...

Embodiment

[0021] see figure 1 , the present embodiment is to provide a shield tail seal brush structure that increases the spring plate to improve the resilience, which includes the shell plate 10; the front protective plate 12, the rear protective plate 14 and the front and rear protection plates 12 are fixed in the shell plate 10 by pins 11. There are at least two layers of stainless steel wire groups 15 between the protective plates. In this embodiment, two layers of stainless steel wire groups 15 are fixed inside the shell plate 10, and a stainless steel wire mesh 16 and a spring plate are added between the two stainless steel wire groups 15. 13. The two layers of stainless steel wire groups 15 are separated by a stainless steel wire mesh 16, and the length of the stainless steel wire mesh 16 protruding from the shell plate 10 is close to the length of the second wire layer of the stainless steel wire group 15.

[0022] It is worth mentioning that the spring plate 13 is a spring ste...
