Summary of the invention
The object of the present invention is to provide a kind of job practices that adopts the whole dark digging method to perform the subway station transfer node, this job practices can reach the purpose of reserving at a specified future date, can save initial investment effectively again, can also effectively reduce investment risk; Construction period, traffic above-ground, other surrounding enviroment of underground utilities there is not influence substantially.
A kind of job practices that adopts the whole dark digging method to perform the subway station transfer node provided by the invention is characterized in that adopting earlier hidden construction process construction initial stage subway station agent structure, and reserves good metro station construction interface at a specified future date; Finish transfer node in the tunneling mode in the early stage the reservation conditions basis during at a specified future date metro station construction.
Further perfect as job practices of the present invention, apply the necessary retaining structure of structure vertical applied force underpin system and subway station at a specified future date of initial stage subway station when adopting hidden construction process construction initial stage subway station, structure vertical applied force underpin system comprises the wall, post of initial stage subway station etc.
Further perfect as job practices of the present invention, the structure vertical applied force underpin system of initial stage subway station can be constructed together in conjunction with the permanent structure support system of subway station at a specified future date.
Further perfect as job practices of the present invention carries out local stiffening and improvement to position, subway station at a specified future date metro station construction the time when geology is relatively poor in the early stage.
The main thought that employing whole dark digging method provided by the invention performs the job practices of subway station transfer node is: during hidden construction process construction initial stage subway station, the essential retaining structure in subway station at a specified future date in the range of nodes of constructing simultaneously is for metro station construction at a specified future date is carried out early-stage preparations; The vertical applied force underpin system that applies the initial stage subway station should be considered the possibility that underpins long term, purpose is when constructing long term, existing station load vertical applied force underpin system still can keep stable after emptying the soil body of reserving the transfer node place when tunneling, can not influence the safe operation of existing subway line to guarantee construction at a specified future date.When geology is very poor, local stratum consolidation is carried out at position, subway station at a specified future date metro station construction the time in the early stage.
Compare with existing full cut and cover method technology, the present invention has the following advantages:
1. adopt whole dark digging method construction subway station transfer node, traffic above-ground, underground utilities are not had influence substantially.
2. on node was reserved, the initial stage mainly was retaining structure and a vertical applied force underpin system of reserving necessity of planning subway line at a specified future date, and the initial stage drops into seldom, and economy is outstanding.
3. the initial stage only performs necessary retaining structure and vertical applied force underpin system, and the advance works amount is little, and construction in later period is more convenient, flexible; Even planning is adjusted simultaneously, the engineering quantity of loss is also little, has reduced investment risk widely.
