It is usually exposed；Filling-type Karst cave refers to that the entire hole body of solution cavity is largely full of by detrital sediment, chemical sediment or underground water.
Shield-tunneling construction meet solution cavity region (it includes numerous a solution cavity cavitys) construction when, especially solution cavity when on shield-tunneling construction line,
Easily there are accidents such as " planting head " " subsideing " " water burst " " prominent mud " " riverbed collapse " in Shield-type machinery.
For ensure shield machine safely, pass through solution cavity area, need to intrusion 1.5 times of hole diameters of tunnel main line within the scope of it is numerous
A solution cavity cavity is filled consolidation process with cement slurry, reduces the relative settlement between Different Strata to meet, reduces section of jurisdiction
Leakage, to guarantee the shield tunnel construction phase and run the safety of phase.Traditional solution cavity cavity packing technology uses steel sleeve guard aperture,
Intert the method for a Grouting Pipe in hole, basically as underwater concrete technology is poured, Grouting Pipe needs to be embedded to institute's injection slurry
Interior certain depth, it is intermittent with slip casting depth to promote Grouting Pipe upwards, finally with fast dry concrete by solution cavity packing.But this
There are many drawbacks for technology, cause collapse hole phenomenon to lead to the extremely difficult extraction of Grouting Pipe or pressure since hole wall stratum sandy gravel stratum is blocked up
It is unbalanced to cause solution cavity bottom boundaries spillage phenomenon.Especially its hole is close within the scope of 1.5 times of hole diameters of tunnel main line and work surface
The ultra-large type solution cavity that solution cavity cavity communicates can not only be consumed with the fast dry concrete solution cavity packing technology packing ultra-large type solution cavity
A large amount of injection slurry increases considerably filling cost, also tends to be difficult to achieve the purpose that solution cavity packing；Solution cavity packing is caused to lose
It loses, tunnel main line is relocated, and loss is serious.
