Description
Technical Field
The invention relates to a thermodynamic tunnel structure and a construction technology, in particular to a connection structure and a method for shield tunnel segments and brackets, which can ensure that the segments and cast-in-situ brackets are formed into a reinforced concrete whole by arranging a reinforcing steel bar connector between the prefabricated segments and the brackets so as to ensure that a connection node has enough strength and rigidity to transfer axial force, bending moment and shearing force, thereby being beneficial to the stress stability of a tunnel compartment structure, reducing segment processing difficulty and improving construction efficiency.
Background
The shield technology is increasingly applied to the construction of highways, railways, urban rail transit and municipal pipeline engineering. Rapid, efficient and safe is a significant advantage of shield technology. But the shield section is single in form, so that the application of the shield in various industries is limited. In order to meet the requirements of different functions, the cross section of the shield tunnel is usually divided, so that the purpose of dividing bins is achieved. However, the inventors have found that there are a number of difficulties in the binning of shield tunnels, for example, the connection between the tube sheets and the internal binning structure such as the baffle. Because the shield segments are prefabricated structures, and the internal structures of the shield tunnels are usually cast in place, the parts are organically integrated for structural safety. It is therefore desirable to be able to withstand sufficient axial forces, bending moments and shear forces at the nodes. If no special connection measures are taken, the bearing capacity at the node is insufficient, which becomes a hidden danger of structural safety. And secondly, the difficult problem of segment design caused by node details. If the nodes and the duct piece are prefabricated together, the manufacturing difficulty of the duct piece is increased, and meanwhile, the difficulty is brought to the processing of the duct piece die. The common adopted dividing mode in the shield tunnel is mainly divided into upper and lower dividing modes, and the adoption of the bracket to separate the middle partition plate for the upper and lower dividing modes is a reasonable and simple method for stress. Therefore, special design is required for the connection node of the bracket structure and the shield segment. For example, the in-situ casting mode usually adopts a reinforcement planting mode, on one hand, the method usually needs to damage the segment structure, and certain damage is caused to the integrity of the structure; on the other hand, in order to protect the safety of the shield tunnel structure segment to the greatest extent, the depth of the reinforcing steel bar implanted into the segment and the type of the reinforcing steel bar are relatively smaller, so that the bearing capacity of the cast-in-situ bracket structure by the connecting method is greatly reduced. The inventor believes that if a rebar connector is provided between the prefabricated segment and the bracket, the segment and the cast-in-place bracket can be made into a reinforced concrete whole to ensure that the connection node has sufficient strength and rigidity to transmit axial force, bending moment and shearing force. In view of this, the inventors have conceived of the present invention.
