Description
Technical Field
The utility model relates to a tunnel engineering technical field, concretely relates to shield constructs quick-witted slip casting pipeline convenient to wash.
Background
In the shield construction process, grouting operation needs to be carried out synchronously, and in the extremely short time of formation of a shield tail gap, grouting materials need to be filled, so that surrounding rock and soil bodies are supported timely, ground surface settlement can be controlled, rock and soil collapse is guaranteed, and deformation and leakage prevention after shield tunnel construction are guaranteed.
In the grouting process, the solidification time of the grout is generally 3-10 hours, and if the grouting pipe is not cleaned in time after the grouting is finished, the grouting pipe is easy to block, so that the next grouting construction is influenced, and the shield construction is also influenced. The mode that the slip casting pipe was washd with the water pipe after adopting the segmentation to unpack apart the slip casting pipe to the tradition, and the operation is not walked complicacy, wastes time and energy, and the scavenging period of every time all needs more than 6 hours, influences work efficiency, also causes the loss of shutting down for the shield structure construction.
SUMMERY OF THE UTILITY MODEL
To the problem that exists among the above-mentioned prior art, the utility model provides a shield constructs quick-witted slip casting pipeline convenient to wash can effectually realize avoiding the slip casting pipe to block up to slip casting pipe clearance, and convenient operation is swift, obviously improves work efficiency, guarantees the job schedule that the shield constructs the construction.
The utility model discloses the technical scheme who adopts does:
the utility model provides a shield constructs quick-witted slip casting pipeline convenient to wash, includes the slip casting pipe, the position slope that is close to the entrance point on the slip casting pipe is equipped with branch pipe one, the position slope that is close to the exit end on the slip casting pipe is equipped with branch pipe two, the intussuseption of branch pipe is filled with the foam ball, the inner wall sliding connection of branch pipe one has and is used for advancing the foam ball in the branch pipe one to the intraductal piston rod of slip casting, detachable being connected with carries out the shutoff to branch pipe two on the branch pipe two.
The first branch pipe is arranged at a position, close to the inlet end of the grouting pipe, on the grouting pipe, the piston rod is arranged in the first branch pipe, a foam ball filled in the first branch pipe can be pushed into the grouting pipe from the first branch pipe under a proper condition, after grouting is completed by the grouting pipe, the foam ball can be pushed into the grouting pipe while high-pressure water is introduced into the pipe, the foam ball enters the grouting pipe to realize isolation of high-pressure water and slurry, the high-pressure water continuously enters the grouting pipe to push the foam ball to move towards the outlet end of the grouting pipe, and the pressure of the slurry is higher as the pressure of the slurry is closer to the outlet end when the foam ball enters the grouting pipe, so that the second branch pipe close to the outlet end of the grouting pipe becomes the outlet of the foam ball when the high-pressure water continuously impacts the grouting pipe.
For the sake of more clear description, the area of the inside of the grouting pipe behind the lower port of the second branch pipe is a grouting end area, and in the grouting process, in order to avoid the overflow of the grout from the second branch pipe, therefore, during grouting, the blocking piece blocks the second branch pipe, when the grout is gradually pushed to the grouting end area by the foam ball, the blocking piece can be opened, the foam ball can float upwards under the impact of high-pressure water, and overflows from the second branch pipe, so that the recovery of the foam ball is realized.
The foam ball has the characteristics of light weight and easy deformation, can smoothly pass through under the condition that the grouting pipe has a curve, can gradually move along the inner wall of the grouting pipe under the impact of high-pressure water, can achieve the better cleaning effect on the inner wall of the grouting pipe, is more thorough in cleaning, and avoids the trouble that the traditional grouting pipe needs to be cleaned in a segmented manner. This project organization, it is intraductal directly to adopt when suitable to push the slip casting with the foam ball, and the in-process that the foam ball was advanced to the water under high pressure removes has just played fine clearance effect to the inner wall of slip casting pipe, and the foam ball can be retrieved through branch pipe two. This slip casting pipeline can effectually realize avoiding the slip casting pipe to block up the slip casting pipe clearance, and convenient operation is swift, obviously improves work efficiency, guarantees the job schedule of shield structure construction.
Furthermore, the foam balls filled in the first branch pipe are divided into scattered foam balls and furled foam balls wrapped by the string bag, the scattered foam balls are far away from the piston rod, and the furled foam balls are close to the piston rod.
The foam ball adopts two kinds of modes, one kind is that the foam ball of direct scattering form is filled at the lower extreme of branch pipe one, another kind is that adopt the string bag to wrap up a plurality of foam balls, avoid the foam ball comparatively scattered under the impact of high pressure water, can not reach the better effect of clearing up with the inner wall of slip casting pipe, the string bag wraps up draws in the form foam ball and fills in the upper end of branch pipe two, at the in-process that the piston rod impels downwards, the foam ball that advances the scattering form in the slip casting pipe advances in proper order, the form foam ball that draws in that the back income slip casting pipe is then located the rear end of the foam ball of scattering form, also be, high pressure water directly strikes drawing in the form foam ball, can guarantee the whole propulsion effect of foam ball at the in-process that impels the foam ball gradually, thereby reach better clearance effect.
Certainly, because drawing in the form foam ball is overall structure, also be at the whole propulsive in-process of foam ball, drawing in the form foam ball and keeping apart the foam ball of high pressure water and form that scatters, it erodees the foam ball of form that scatters to thick liquid one side also to have reduced high pressure water as far as possible, certainly because the design of branch pipe two, can guarantee the timely discharge of foam ball, it needs to explain that because under the effect of high pressure water, probably have a small amount of foam ball to enter into the thick liquid, a small amount of foam ball can not exert an influence to the slip casting construction, can ignore.
