Description
Technical field
The utility model relates to tunnel jacking construction, particularly relates to a kind of fluid circuit continuous type jacking construction device and apply
Work method.
Background technique
Due to push-bench construction when have can guarantee top traffic do not interrupt, originate received well size it is smaller, to ring
The advantages that border change is small, pollution is small, so that jacking construction is quickly grown in recent years.But jacking construction is also deposited at many aspects
In biggish defect.For example, requiring to remove fluid circuit before transferring new tube coupling every time, placed in new tube coupling
After, while time-consuming and laborious, the fluid of spilling also can largely influence the construction environment in tunnel.Due to the above problem
Presence so that the efficiency of jacking construction is far below cut and cover tunneling, in addition jacking construction length of tunnel is generally all shorter, from
And limit the popularization and development of pipe jacking method.How to realize that push-bench is continuous, efficiently construction has become and needs to be solved
The problem of.
Utility model content
The utility model proposes a kind of fluid circuit continuous type jacking construction device and construction methods, solve existing push pipe
The problem that machine needs push-bench construction efficiency caused by frequent disconnection, connecting fluid pipeline low when construction.
The technical solution of the utility model is achieved in that a kind of fluid circuit continuous type jacking construction device, including
Tube coupling and external pipeline, the tube coupling is interior to be equipped with fluid channel, and fluid channel is equipped with the non-return machine positioned at tube coupling female end
Structure and trigger mechanism positioned at tube coupling socket end, external pipeline are equipped with valve, and the exit of external pipeline is equipped with trigger mechanism.
The external pipeline is located on top-pushing mechanism.
It is equipped with reserved steel pipe in the tube coupling, reserves steel duct and forms fluid channel.
The part that the reserved steel pipe stretches out tube coupling socket end is trigger mechanism.
The non-return mechanism is check-valves.
Sealing is equipped between the tube coupling female end of preceding tube coupling and the tube coupling socket end of posterior joint.
The sealing includes tube coupling end face seal.
The sealing includes fluid circuit sealing.
The advantages of the utility model: when driving, the connection of fluid channel is realized in trigger mechanism and non-return mechanism cooperation；Under
Guan Shi, non-return mechanism carry out non-return to channel, avoid the leakage of fluid；Very good solution jacking construction process medium fluid pipeline
The problem of frequently cutting off with connecting improves push-bench construction efficiency.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is tube coupling connection schematic diagram before and after the utility model.
Fig. 2 is the utility model rearmost end tube coupling connection schematic diagram.
In figure: 1- tube coupling female end, 2- tube coupling end face seal, the sealing of 3- fluid circuit, 4- non-return mechanism, 5- trigger machine
Structure, 6- tube coupling socket end, 7- valve, 8- top-pushing mechanism.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are under that premise of not paying creative labor
Every other embodiment obtained, fall within the protection scope of the utility model.
As illustrated in fig. 1 and 2, a kind of fluid circuit continuous type jacking construction device, including tube coupling and external pipeline, in tube coupling
It is axial to arrange reserved steel pipe, it reserves steel duct and forms fluid channel, reserve steel pipe and stretch out tube coupling socket end 6, stretch out tube coupling and insert
Trigger mechanism 5 of the part at mouth end 6 as non-return mechanism 4, fluid channel are equipped with the non-return mechanism 4 positioned at tube coupling female end 1,
Non-return mechanism 4 is specially check-valves.Tube coupling end is equipped between the tube coupling female end 1 of preceding tube coupling and the tube coupling socket end 6 of posterior joint
Face sealing 2 and fluid circuit sealing 3, when push-bench correction or curved section tunnel, for preventing fluid from leaking.All extension tube attacheds
Road is located on the top iron on top-pushing mechanism 8, and the exit of external pipeline is equipped with valve 7, for closing after the completion of ring driving
Fluid circuit, prevents fluid overflow, and the exit of external pipeline is equipped with the trigger mechanism 5 of non-return mechanism 4.
The working principle of above-mentioned apparatus is: in tunneling process, the check-valves on tube coupling is shown in a fully open operation, when fluid passes through
Position needed for not having the pressure loss, fluid to reach from ground through the reserved steel pipe built in the iron access tube coupling of top.Transferring new pipe
When section, first close top iron on valve 7, later will top iron retreat, now close to top iron a section tube coupling due to tube coupling female end 1
Check-valves without trigger mechanism 5, and be in close state, fluid is not flow backwards.After transferring new tube coupling, new tube coupling
The trigger mechanism 5 of tube coupling socket end 6 triggers the check-valves of upper endless tube section, again opens channel, the valve 7 for pushing up iron is opened
Afterwards, fluid enters the fluid channel built in tube coupling, can carry out driving process.
A kind of fluid circuit continuous type pipe jacking construction method, the reserved steel pipe inside tube coupling form fluid channel, reserve steel
The part that pipe stretches out tube coupling socket end 6 forms trigger mechanism 5, when driving, the non-return of tube coupling before the trigger mechanism 5 of rear tube coupling triggers
Mechanism 4, the trigger mechanism 5 of external pipeline trigger the non-return mechanism 4 of rearmost end tube coupling, and the fluid channel between the tube coupling of front and back connects
Logical, external tube coupling is connected to the fluid channel of rearmost end tube coupling；When down tube, the valve 7 on external pipeline, top-pushing mechanism 8 are closed
Drive external pipeline mobile, external pipeline retreats, and the non-return mechanism 4 of rearmost end tube coupling is closed, between new joint and front end tube coupling
If sealing.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
