Description
Technical field
The present invention relates to constructing tunnel equipment technology field, a kind of isoplanar for rich water cobblestone stratum
Multi-cutter-disk rectangular tunnel boring machine.
Background technology
Along with expanding economy, urbanization process is gradually accelerated, and space, road surface is more and more less, and subterranean tunnel construction has become
A new direction for current the realm of building construction.Rectangular tunnel boring machine has space availability ratio height, earthing is shallow and is constructed into
The advantage of this relative moderate, its more circular push pipe of effective usable floor area increases more than 20%.Current domestic rectangular tunnel boring machine is also
It is confined to only adapt to the conventional rectangular tunneler of the soft soil layer such as silt, viscous, powder, sand, but in field, rich water cobblestone stratum
The application of rectangular tunnel boring machine or blank.
Cobblestone formation stability is poor and contains fine sand, and mobility is strong, cannot form natural agent arch when tunnel excavation, i.e.
Face is unstable, phenomenon of easily caving in.Rectangular tunnel boring machine is typically, by combining cross arrangement before and after multiple cutterheads, to depend on
Mutually making up of forward rear cutterhead excavation face, reduces the excavation blind area of rectangular area as far as possible.But this cutterhead combination shape
Formula is relatively big to the disturbance of the soil body, and stirring region is limited, dregs poor fluidity, is therefore only applicable to the metastable operating mode in stratum
Under, in rich water cobblestone stratum, front and back the excavation difference of cutterhead provides space for gushing of drift sand, easily causes the soil body to cave in.
Simple cutterhead isoplanar is arranged and although face can be played certain support, but cobblestone stratum drift sand under extreme case
Still can gush spray through equipment and form solution cavity, this situation once occurs this how to solve, how settlement Control ensures also is equipment construction
Required problems faced.Additionally, cutterhead isoplanar arrange also result in bigger excavation blind area, in this stratum rich in big
The discharge of size cobblestone it is also proposed challenge.
Therefore, the problems demand how realizing rich water cobblestone stratum Rectangular Tunnel non-excavating construction solves, a kind of applicable
Rectangular Tunnel digging device in rich water cobblestone stratum is needed badly and is provided.
