Abstract
The utility model discloses a kind of TBM construction inverted arch block holding devices, described device includes Y type mandril (1) and chain (2), one end of the chain (2) is connect with the middle part of Y type mandril (1), and the other end of the chain (2) is provided with standing screw (3)；The middle part of the chain (2) is connect by hydraulic cylinder (4) with the upper end of Y type mandril (1).The utility model has the advantages that structure is simple and convenient to operate, using reliable, low in cost, it can be quickly and easily by the inverted arch block newly installed and mounted inverted arch prefabricated section jam-packed using it, it improves and holds out against quality, sealing material is enabled to obtain useful effect, it is therefore prevented that the generation of later period tunnel inverted arch leakage problem.
Description
Technical field
The utility model relates to a kind of TBM constructing device, especially a kind of TBM construction inverted arch block holding device.
Background technique
With national project build in major long tunnel construction it is more and more, TBM is existed due to efficient, environmentally friendly, safe feature
It is widely adopted in tunnel construction.In the tunnel of TBM method construction, some tunnels use Prefabrication inverted arch prefabricated section outside hole,
Then it is installed and used in hole；Wherein, it when in hole using inverted arch loop wheel machine installation inverted arch prefabricated section, usually will can not newly install
Inverted arch block and mounted inverted arch prefabricated section jam-packed, in this case, operator generally uses crowbar to hold out against, due to people
Work holds out against poor quality's control, and gap causes sealing material that can not play effective stop often beyond specified value between inverted arch block
Water effect, causes later period tunnel inverted arch percolating water.
Utility model content
The purpose of this utility model is just to provide a kind of easily TBM that inverted arch prefabricated section is held out against can construct and face upward
Arch block holding device.
The purpose of this utility model is that technical solution in this way is realized, a kind of TBM constructs inverted arch block holding device,
Described device includes Y type mandril and chain, and one end of the chain is connect with the middle part of Y type mandril, the other end of the chain
It is provided with standing screw；The middle part of the chain is connect by hydraulic cylinder with the upper end of Y type mandril.
For the ease of the connection of hydraulic cylinder, be provided with connecting plate in the middle part of chain, one end of the hydraulic cylinder with
Connecting plate is movably connected with, and the other end of the hydraulic cylinder is connect with the upper end inner face of Y type mandril.
It withstands on prefabricated section for the ease of Y type mandril, is provided on the inside of two stabilizer blades of the lower part of the Y type mandril
Jacking block.
By adopting the above-described technical solution, there is the utility model structure to be simple and convenient to operate, using reliable, cost
Cheap advantage can be mentioned using it quickly and easily by the inverted arch block newly installed and mounted inverted arch prefabricated section jam-packed
It is high to hold out against quality, enable sealing material to obtain useful effect, it is therefore prevented that the generation of later period tunnel inverted arch leakage problem.
Detailed description of the invention
The Detailed description of the invention of the utility model is as follows:
Fig. 1 is the cross-sectional configuration schematic diagram of the utility model；
Fig. 2 is the longitudinal plane structure schematic diagram of the utility model.
Specific embodiment
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing, but the utility model
These embodiments are not limited to, any improvement or substitution on the present embodiment essence spirit still falls within the utility model
Claim range claimed.
Embodiment 1: as shown in 1,2, a kind of TBM construction inverted arch block holding device, described device includes Y type mandril 1 and lock
One end of chain 2, the chain 2 is connect with the middle part of Y type mandril 1, and the other end of the chain 2 is provided with standing screw 3；It is described
The middle part of chain 2 is connect by hydraulic cylinder 4 with the upper end of Y type mandril 1.
For the ease of the connection between hydraulic cylinder and chain, the middle part of chain 2 is provided with connecting plate 5, it is described hydraulic
One end of oil cylinder 4 is movably connected with connecting plate 5, and the other end of the hydraulic cylinder 4 and the upper end inner face of Y type mandril 1 connect
It connects.
It withstands on prefabricated section for the ease of Y type mandril, is respectively provided on the inside of two stabilizer blades of the lower part of the Y type mandril 1
There is jacking block 6.
The utility model is to use in pairs.The utility model works in this way: sharp first when mating formation inverted arch prefabricated section
Inverted arch prefabricated section 7 to be installed is allocated and transported to erecting bed, the parameters such as its absolute altitude of first successive step and position with inverted arch loop wheel machine, fixed
Screw rod 4 is fastened in mounted 8 lifting hole(eyelet) of inverted arch prefabricated section, and Y type mandril 1 lower end two jacking block 6 is withstood on inverted arch prefabricated section
Outer side edges are started hydraulic cylinder 4, are pushed up inverted arch prefabricated section 7 to be installed and mounted inverted arch prefabricated section 8 using lever principle
Tightly, mounted inverted arch prefabricated section lower concrete is backfilled, hydraulic cylinder 4 is withdrawn, unlocks standing screw 3, it is prefabricated to complete inverted arch
Block is mated formation, and the installation exercise of subsequent cycle is carried out.
