Abstract
The invention discloses an assembling type connecting aisle structure and a construction method thereof. The assembling type connecting aisle structure is characterized by comprising a shield tunnel concrete segment, a shield tunnel composite segment, an inter-segment connecting system, a connecting aisle steel segment and a connecting aisle concrete segment. The shield tunnel composite segment comprises a composite segment steel segment section, a composite segment concrete segment section and a reserved reinforcing body box, the outer side of the composite segment steel segment section is connected with the shield tunnel concrete segment through connecting bolts in an assembling mode, the inner side of the composite segment steel segment section is integrally connected with the composite segment concrete segment section, and the inner side of the composite segment concrete segment section is connected with the connecting aisle steel segment through the inter-segment connecting system. According to the construction method, the mode of starting with a pipe jacking method and advancing with a shield method is adopted. The assembling type connecting aisle structure and the construction method thereof have the advantages the quality is controllable, the integrality with a shield tunnel is high, and joint waterproofness is high; and the starting problem of narrow and small spaces is solved, and the construction axis of a connecting aisle can also be easily controlled.
Description
technical field [0001] The invention relates to a communication channel structure and a construction method thereof, in particular to an assembled communication channel structure and a construction method thereof, belonging to the field of underground engineering. Background technique [0002] According to 19.1.22 of the "Code for Metro Design" GB50157-2003: between two single-line interval tunnels, when the continuous length of the tunnel is greater than 600m, a connecting passage should be set up. Therefore, a large number of subway tunnels are provided with communication passages between the uplink and downlink lines. At present, the communication channel is generally horseshoe-shaped, and is reinforced by the freezing method and then constructed by the mining method. However, this method has the following disadvantages: (1) Due to the constraints of the structure, it is difficult to carry out mechanical excavation, and the speed of manual excavation is slow. The quality...
