Abstract
The invention discloses a kind of minor diameter compression concrete side wall machines, the thrustor on the inside of the shield shell is arranged at intervals on including conehead, shield shell and at least two, one end of the shield shell is connected with the rear end of the conehead, the thrustor includes installation end and pushing end, the pushing end of the thrustor pushes against the rear end of the conehead against the front end in tunnel, the installation end of the thrustor.In the use of the present invention, pushing tow, conehead are advanced slowly thrustor forward, soil is directly expressed to conehead surrounding, then thrustor is packed up, and the space that pushing tow comes out, the built tunnel again in the space are formd between conehead and tunnel, then the pushing end of thrustor is resisted against to the front end of newly built tunnels, finally start thrustor, minor diameter tunnel is finally hole-throughd in such cycle operation, it not only uses manpower and material resources sparingly, also improves construction efficiency.Therefore, compared with prior art, the present invention has construction efficiency high, the advantages of using manpower and material resources sparingly.
Description
Technical field
The present invention relates to engineering machinery fields, and in particular to a kind of minor diameter compression concrete side wall machine.
Background technique
With China's socio-economic development, underground engineering is more and more, therefore, underground construction also just more and more, employment
Power is excavated or excavator excavates the certainly not faster and better completion excacation of method, and at this time shield machine just comes into being.
Especially be used to install the pipelines of media such as conveying water, electricity, oil, gas is building minor diameter tunnel, can only use shield machine.
In shield machine construction, shield machine is tunneled forward, and then construction personnel transports soil in tunnel, both unrestrained in this way
Take manpower and material resources, and influence construction efficiency, therefore, it's necessary to propose a new technical scheme for this field.
Summary of the invention
The present invention proposes a kind of minor diameter compression concrete side wall machine, solves wasting manpower and material resources of the existing technology, again
The problem of influencing construction efficiency.
To achieve the goals above, the technical scheme is that a kind of minor diameter compression concrete side wall machine, including conehead,
Shield shell and at least two thrustor on the inside of the shield shell is arranged at intervals on, behind one end of the shield shell and the conehead
End is connected, and the thrustor includes installation end and pushing end, and the pushing end of the thrustor is described against the front end in tunnel
The installation end of thrustor pushes against the rear end of the conehead.
Preferably, the conehead is conical structure.
Preferably, the thrustor is hydraulic jack.
Preferably, the number of the thrustor is 6.
Preferably, 6 thrustors are distributed in circumference in equal parts.
Preferably, the shield shell is cylinder-like structure, and the axis of the axis of the shield shell and the conehead is positioned at same
On straight line.
Compared with prior art, the present invention has an advantage that in the use of the present invention, thrustor pushing tow forward, cone
Head is advanced slowly, and soil is directly expressed to conehead surrounding, then thrustor is packed up, and pushing tow is formd between conehead and tunnel
The pushing end of thrustor, is then resisted against the front end of newly built tunnels, finally by space out, the built tunnel again in the space
Start thrustor, such cycle operation finally hole-throughs minor diameter tunnel, not only uses manpower and material resources sparingly, and also improves construction effect
Rate.Therefore, compared with prior art, the present invention has construction efficiency high, the advantages of using manpower and material resources sparingly.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with
It obtains other drawings based on these drawings.
Fig. 1 is the structural diagram of the present invention.
In figure: 1-conehead, 2-shield shells, 3-thrustors, 4-tunnels.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under that premise of not paying creative labor
Embodiment shall fall within the protection scope of the present invention.
As shown in Figure 1, a kind of minor diameter compression concrete side wall machine proposed by the present invention, including conehead 1, shield shell 2 and at least
Two are arranged in the thrustors 3 of the inside of shield shell 2, and conehead 1 can be pyramid or circular cone, and in the present embodiment, conehead 1 is cone
Structure.Thrustor 3 can there are many devices to select, and in the present embodiment, thrustor 3 is hydraulic jack.Shield shell 2 is cylinder
Shape structure, and the axis of shield shell 2 and the axis of conehead 1 are located on the same line.Conehead 1 is when advancing in this way, each section
Stress balance will not deviate desired trajectory during driving because of force unbalance.
As shown in Figure 1, one end of shield shell 2 is connected with the rear end of conehead 1, thrustor 3 includes installation end and pushing end, top
For the pushing end of pushing device 3 against the front end in tunnel 4, the installation end of thrustor 3 pushes against the rear end of conehead 1.
As shown in Figure 1, the number at least two of thrustor 3, in the present embodiment, the number of thrustor 3 is 6.6
A thrustor 3 is distributed in circumference in equal parts.In this way also for conehead 1 during driving stress balance, always along pre-
Fixed track driving.
In the use of the present invention, pushing tow, conehead 1 are advanced slowly thrustor 3 forward, soil is directly expressed to conehead 1
Surrounding, then thrustor 3 is packed up, and the space that pushing tow comes out is formd between conehead 1 and tunnel 4, builds tunnel again in the space
Then the pushing end of thrustor 3 is resisted against the front end of newly built tunnels 4 by road 4, finally start thrustor 3, and so circulation is made
Industry finally hole-throughs minor diameter tunnel, not only uses manpower and material resources sparingly, also improves construction efficiency.
The above is merely preferred embodiments of the present invention, be not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
