Design.Some is overlapping for the tail shield of rock tunnel(ling) machine and the external diameter in pipe-plate lining tunnel, and from around in geologic body by tunnel
Inner sealing.Need to continue to maintain sealing between pressurizing area and atmosphere zone.In order to maintain wire brush in rock tunnel(ling) machine
Sealing, surrounding's geologic body of supercharging must separate with the internal tunnel being under atmospheric pressure.To achieve it, generally need
Will injection material, other method also have and artificial reduce Groundwater behind rock tunnel(ling) machine by the section of jurisdiction of tunnel inside lining
Position.Existing various technical schemes have the shortcomings that respective, can not be in all geologic bodies from rock tunnel(ling) machine injection material possibly
Appropriate sealing is produced in type, thus certain risk be present；Other buildings and environment can be influenceed by reducing groundwater level, if
Tunnel be located at below river, lake or ocean or near, may not accomplish at all reduce groundwater level.In order to carry out tunnel digging
Enter the repairing or replacing of the tail shield sealing brush of machine, it is necessary to have a kind of safe method, subsurface flow when preventing from repairing or changing
Enter.
Utility model content
The deficiency based on more than, the technical problems to be solved in the utility model are to provide a kind of carry and integrate ground freezing pipe
The tail shield of rock tunnel(ling) machine, it can freeze the geologic body around development machine and water, prevent from repairing or change tail shield sealing brush
When underground water flow into.
In order to solve the above technical problems, the utility model employs following technical scheme：
A kind of tail shield of the rock tunnel(ling) machine with integrated ground freezing pipe, including housing, are arranged in housing and freeze
Pipeline and the refrigerant supply system connected with freezing pipeline, the housing are tubular, and the pipeline that freezes is included along described
The circumferentially disposed some ring pipes of housing, the connecting tube connected with the ring pipe, axial direction distribution of the connecting tube along housing, institute
Connecting tube is stated to connect with the refrigerant supply system.
The front portion of the connecting tube is arc and connected with refrigerant supply system that the rear portion of the connecting tube is mounted to institute
State in housing.
Grouting device is provided between adjacent ring pipe.
Wire brush sealing device is additionally provided with the housing, the wire brush sealing device is arranged in the housing
Wall, the pipeline that freezes are set close to housing exterior walls.
Using above technical scheme, the utility model achieves following technique effect：
(1) the tail shield of the rock tunnel(ling) machine provided by the utility model with integrated ground freezing pipe, is integrated with freezing pipe
Line, cooling liquid can be pumped into by ring pipe, to freeze the geologic body and water around development machine, so, rock tunnel(ling) machine
Surrounding can form one and freeze block, sealing system can comprehensively be safeguarded inside rock tunnel(ling) machine；
(2) grouting device is arranged on freeze pipeline between, freeze pipeline close to housing exterior walls set, wire brush sealing device
Inner walls are arranged on, each device can be integrated into tail shield in the case of being increased without the thickness of tail shield, sets and closes
Reason, save material；Also, freeze pipeline to set close to housing exterior walls, wire brush sealing device is arranged on inner walls, cooling effect
Fruit is good, further facilitates dismounting and maintenance.

Fig. 1 is the structure chart of the tail shield for the rock tunnel(ling) machine that the utility model carries integrated ground freezing pipe；
Fig. 2 is A direction views shown in Fig. 1；
Fig. 3 is B-B views shown in Fig. 2；
Fig. 4 is Fig. 2 partial view.
Embodiment
As shown in figure 1, the tail shield that the utility model carries the rock tunnel(ling) machine of integrated ground freezing pipe includes housing 1, if
Put the refrigerant supply system freezed pipeline 2 and connected with freezing pipeline 2 in housing 1, housing 1 is tubular, freezing pipe
Line 2 is included along the circumferentially disposed some ring pipes 21 of the housing, the connecting tube 22 connected with ring pipe 21, connecting tube 22 along
The axial direction distribution of housing 1, connecting tube 22 connect with the refrigerant supply system.
Wherein, in the present embodiment, housing 1 is cylindric.Freezing pipeline 2 is included along the circumferentially disposed some annulars of housing 1
Pipe 21, the connecting tube 22 connected with the ring pipe 21, connecting tube 22 are distributed along the axial direction of housing 1, the front portion of connecting tube 22
221 be arc and to be connected with refrigerant supply system, and rear portion 222 is mounted in the steel construction of tail shield housing 1.Refrigerant supply system
The refrigerant of system, which is transported to, to be freezed in pipeline 2, for freezing geologic body and water around tail shield housing 1, refrigerant supply system
Unite as prior art, will not be repeated here.So, one can be formed around rock tunnel(ling) machine and freezes block, thus can be from tunnel
Sealing system is comprehensively safeguarded inside development machine.
