Description
Technical field
The invention belongs to underground engineering construction field, particularly relate to one closely upper and lower overlap or shield of closely intersecting
Method for tunnel construction.
Background technology
Along with the high speed development of national economy, some developed regions of China have come into and have large-scale developed and utilized underground sky
Between epoch, and the construction of subway will be the emphasis of China's 21 century Urban Underground Space Excavation, and urban skyscraper uses stake
Base is more universal, and the situation of subway sectional tunnel cross-over pile base plinth happens occasionally, for reducing the engineering risk of cutting piles as far as possible
And engineering cost, it may be necessary in some cases to when Tunnel Crossing Piles of Building by the most overlapping for running tunnel or arranged in a crossed manner；Carry out
During the exploitation of plot, for avoiding too much affecting the use in plot because reserved subway passes through condition, the most also press running tunnel upper and lower
Overlapping or intersection is its reserved passageway；In the design process of subway station, move because being changed by traffic data process, pipeline, existing build
(structure) builds the impact of thing, for reducing engineering risk, saving construction investment and reduce the impact on traffic above-ground, car sometimes as far as possible
Stand and use side platform scheme that is left and right line platform is overlapping up and down or that intersect；For realizing the transfer on the same stage of 2 lines, change to two cars
Stand and the most all use the scheme of the left and right line platform side platform of overlap or intersection up and down.When station uses the most overlapping or intersects
Side platform scheme time, the running tunnel at two ends, station also needs local up and down overlapping or intersects.Existing subway construction has been enter into height
Speed developmental stage, is partially or fully used the most overlapping or cross tunnel because limiting by above-mentioned various conditions at Subway Tunnel
Situation will be more and more.
Summary of the invention
In order to solve above-mentioned technical problem, the invention provides one closely overlap or closely intersection shield tunnel up and down
Pipeline construction method, this method can effectively utilize space, reduces engineering risk and the engineering cost of cutting piles as far as possible.
The technical solution adopted in the present invention is:
One closely upper and lower overlap or shield tunnel construction method of closely intersecting, it is characterised in that comprise the following steps:
(1) require according to design and construction organization plan carries out the shield driving of tunnel, bottom or a wherein cross tunnel；
(2) by injected hole grouting and reinforcing bottom tunnel parallel-segment or transposition section stratum, within 270 ° of scopes of tunnel cross-section, length
Both sides, direction respectively beyond parallel-segment or each 5-8m of transposition section, strictly to control pressure and injection rate, it is ensured that shield tunnel during slip casting
Do not deform；
(3) after tunnel grouting solidifies and reaches requirement of strength, tunnel, bottom or transposition section support system are installed, and guarantee support
Install and be in close contact；
(4) require according to design and construction organization plan carries out tunneling tunnel, top parallel-segment or transposition section；Shield duct piece is spelled
Packing quality strictly controls, synchronous grouting harmonious, grouting amount full weight；
(5) parallel-segment or transposition section Full-face pouring to tunnel, top are reinforced；
(6) after grouting and reinforcing section solidifies and reaches requirement of strength, support means is dismantled.
In described step (2), it is 5m that length direction both sides respectively exceed the more excellent distance of parallel-segment or transposition section.
The invention have the benefit that
1, solving the underground space crowded, can make full use of the underground space, subway line is overlapping up and down or intersects, and can enter simultaneously
Row platform is arranged；
2, avoid and relocate, cut some engineering measures such as stake, reduce risk, save construction investment；
3, grouting and propping works all complete in tunnel, reduce traffic above-ground, the interference of building.
