Background technique
It is provided according to 19.1.22 in " metro design code " GB50157-2003: between two single track line tunnels, working as tunnel
When road links up length greater than 600m, service channel should be set.Therefore it is logical contact to be provided between line above and below a large amount of subway tunnels
Road.Service channel is generally the shape of a hoof at present, and using by the way of mining method construction after freezing consolidation, but this method is deposited
In following deficiency: (1) due to structure type constrain, it is more difficult to mechanically excavated, hand excavation's speed slowly and construction quality not
It is easy to control；(2) construction freezing method preparatory stage, construction time, stationary phase are longer；(3) frozen construction can generate disturbance to the soil body, simultaneously
Also structure stress can be adversely affected；(4) after the completion of constructing, the freeze thawing time in later period is long big on surrounding enviroment influence；(5) it applies
Work higher cost.In view of the above problems, portion of techniques personnel propose push bench process connection channel construction method, it is detailed in patent of invention
" construction method of tunnel contact passage in shield section of underground railway ".Although this method is excavated using mechanical, it is suitable for small space
The advantages of driving, but still need to carry out pre-reinforcement to the soil body, construction cost is higher.In order to reduce cost, explore the soil body not
Freezing Method for Cross-passage Construction is carried out in the case where reinforcing, to be solved first is Segment design problem at service channel.The soil body
In the case of reinforcing, since the soil body has certain intensity, joined after can directly removing tunnel duct piece corresponding to service channel
Network passage construction.In the unguyed situation of the soil body, the especially soft soil layer soil body is softer, and directly removing tunnel-liner necessarily causes
Sediment failure pours in outside tunnel, causes engineering accident.
