Embodiment Construction

[0033] According to the foregoing, various diseases will occur in the shield segments in the tunnel due to environmental impacts such as ground stacking, surrounding foundation pit excavation, and changes in groundwater resources. When the disease phenomenon of the shield segment is serious, such as water leakage, grout leakage, deep cracks, etc., the existing repair and reinforcement methods of the shield segment are only grouting reinforcement at the diseased location, and then fixing a piece The steel plate is used to reinforce the defect position of the shield tunnel segment, and it is difficult to achieve a long-term leakage plugging effect.

[0034] After the inventor’s specific analysis, when the shield segment in the tunnel has cracks, water leakage and other diseases, only repairing and strengthening the diseased location cannot prevent the disease from recurring in other positions of the shield segment in the tunnel, and only Reinforcing steel plates at the diseased loc...

Abstract

The invention relates to the technical field of shield tunnel segment construction, in particular to a reinforcement device of shield tunnel segment in a shaped tunnel and an installation method thereof. The reinforcement device comprises two bracket supports, connecting plates and supporting plates. The two bracket supports are oppositely arranged on a track bed at both sides of a track, and theconnecting plate is used to connect two oppositely arranged bracket supports. The supporting plate is in the form of a C with an opening, and is fitted to the surface of the shield tunnel segment in the tunnel. The supporting plates on both sides of the opening are respectively connected with two oppositely arranged bracket supports. The reinforcement device of shield tunnel segment in shaped tunnel provides a reinforcement device with supporting plates, bracket supports and connecting plates, which forms a ring support for shield tunnel segments in a tunnel, so that the shield tunnel segmentsin the circumferential direction of the tunnel can be evenly reinforced. The problems of continuous leakage and easy deformation of tunnel are solved effectively.

Description

Technical field [0001] The invention relates to the technical field of tunnel shield segment construction, in particular to a reinforcement device for a shield segment in a formed tunnel and an installation method thereof. Background technique [0002] Shield segment is the main assembly component of shield construction in urban rail transit. It is the outermost barrier of the tunnel and bears the role of resisting soil pressure and groundwater pressure. The shield segment is the permanent lining structure of the shield tunnel. The quality of the shield segment itself and the installation quality are directly related to the overall quality and safety of the tunnel, and affect the waterproof performance and durability of the tunnel. [0003] Although the quality of shield tunnel segments and installation quality can be strictly controlled and screened during construction, as the operating time of the urban railroad increases and the surrounding environment changes, disease phenomena...
