Abstract
Airport taxi runway subsidence control method in being run the present invention relates to a kind of shield crossing, comprises the concrete steps that：（1）The adjustment of shield driving parameter is instructed by comprehensive monitoring measure, wearing installation opportunity field plane track under control shield can normal operation；(2) by carrying out grouting and reinforcing to tunnel upper half ring soil layer, airport plane track posterior settlement is effectively controlled；The present invention uses simple and practicable construction method, effectively controls the influence generated during shield crossing and later stage operation to airport taxi runway, reaches safety, reduction surrounding enviroment influence purpose.
Description
Technical field
The present invention relates to the construction method that a kind of shield wears important structure building under, especially a kind of shield crossing airport
Plane track (in operation) subsidence control method.
Background technology
With the development of metro construction, the situation of the important structure building of shield crossing is more and more, complicated and changeable
The characteristics of cause extreme influence to shield construction, handle duration and cost often well beyond expection.Therefore, it studies and complete
The construction method of the important structure building of kind shield crossing, becomes a problem urgently to be resolved hurrily.
Therefore, it is necessary to be directed to the construction characteristic of shield crossing airport taxi runway (in operation), worn under shield by studying
Airport taxi runway construction technology captures under shield and wears the technical barrier of airport taxi runway in operation, it was demonstrated that shield construction
Airport infrastructure construction in applicability and reliability, for domestic and international airport infrastructure construction provide more thinkings and
Selection, strengthens the popularity and sustainability of the application of shield construction technique, while promotes socio-economic development, meets social need
It asks.
Invention content
The present invention is to provide for airport taxi runway subsidence control method in a kind of shield crossing operation, to improve shield
Pass through the purpose of important structure building construction method.
To achieve the above object, the technical scheme is that：Airport taxi runway settles in a kind of shield crossing operation
Control method, the specific steps are：
(1) adjustment of shield driving parameter is instructed by comprehensive monitoring measure, installation opportunity field is worn under control shield and slides
Runway can normal operation；
(2) by carrying out grouting and reinforcing to tunnel upper half ring soil layer, the posterior settlement of airport plane track is effectively controlled.
The specific method of the comprehensive monitoring measure：Deep layer monitoring holes are set, bury automatic monitoring device, are formed with certainly
Based on dynamic monitoring, the monitoring system supplemented by personal monitoring, the comprehensive monitoring measure being combined using automatic monitoring and personal monitoring.
The specific method of the tunnel upper half ring grouting and reinforcing：Injected hole is reserved by section of jurisdiction, Grouting Pipe is inserted into corresponding soil
Cement grout by multiple, a small amount of, uniform slip casting principle, is relatively evenly injected soil by layer, combined ground settlement monitoring data
Layer, to control airport plane track posterior settlement.
The beneficial effects of the invention are as follows：
The present invention is directed to the construction characteristic of shield crossing airport taxi runway (in operation), can by this construction technology
Crossing construction is carried out while the safe handling of airport taxi runway is ensured, has given full play to shield-tunneling construction technique on homogeneous stratum
The advantages that middle disturbance is small, speed of application is fast, sedimentation is easily controllable, further reduces the influence to surrounding enviroment, is domestic and international machine
Field infrastructure construction provides wider thinking and selection, makes full use of the underground space, increases economic efficiency.
Description of the drawings
Fig. 1 is slip casting flow chart in method of the invention；
Grouting Pipe schematic diagram when Fig. 2 is non-slip casting state；
Grouting Pipe diagram when Fig. 3 is slip casting state is intended to.
Specific embodiment
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
A kind of shield crossing airport taxi runway (in operation) subsidence control method, Specific construction step are as follows：
(1) comprehensive monitoring measure
The soil layer that shield crossing taxiway is related to is 4. silt clay, while be close to upper strata 3. 2 sandy silt, and chiltern
Silt sensitivity is higher, and sedimentation is also easy to produce after disturbance.And airport taxiway road structure is thicker, Qi Dao faces are 40cm (20+
20) roadbed of+36~42cm of solid cement stabilization gravel thickness cast-in-place concretes, also 50cm thickness, the sedimentation of the lower section soil body are difficult to
Road surface embodies in time.It under condition of not suspending on airport limitation, is limited, is not enough to full for the automatic monitoring location of taxiway
Sufficient engineering monitoring demand in the case that personal monitoring is limited there is also entry time, need to set deep layer monitoring holes, bury automation
Monitoring device is formed based on monitoring automatically, the monitoring system supplemented by personal monitoring.
(2) tunnel upper half ring grouting and reinforcing measure
Tunnel soil body consolidation grouting, as shown in Figure 1, being inserted into Grouting Pipe (see Fig. 2) and from tunnel using by section of jurisdiction injected hole
Soil layer carries out the reinforcement measure of slip casting outside section of jurisdiction in road.First preformed hole is dredged with impact drill during consolidation grouting, then by 2 meters
Slip casting tube vibration inserts in the hole at 1.75 meters on the outside of tunnel tube wall；With special blowout hookup being installed, and will be unidirectional
Ball valve is connected in Grouting Pipe (see Fig. 3), so as to slip casting.If have the situation that slurries or underground water leak, first blowout prevention is filled
It puts in preformed hole, and connects non-return valve, slip casting seamless steel pipe is directly squeezed into prescribed depth, underground is prevented to reach
The purpose of water or slurries leakage.
