Abstract
The utility model discloses a grouting system of a split starting shield tunneling machine and solves the problem that an own grouting system of an existing shield tunneling machine cannot be used normally. The grouting system is characterized in that a shield tunneling machine head (3) is arranged at the front end of a forming tunnel (1), a muck conveying belt (4) and a muck box (5) are arranged on the rear side of the shield tunneling machine head (3), the grouting system (8) is arranged in a shield shaft (2) and communicated with a shield tunneling machine head grout outlet (6) on the shield tunneling machine head (3) through a grout conveying pipeline (7), a grout stirring system (12) and a grout conveying pump (10) are arranged on the ground, an outlet of the grout conveying pump (10) is communicated with the grouting system (8) through a grout conveying pipeline (9), an outlet of the grout stirring system (12) is communicated with an inlet of the grout conveying pump (10). By the grouting system, a gap between the forming tunnel and a soil body is filled timely, so that subsiding of the ground is avoided.
Description
Technical field
The utility model relates to a kind of filling system, particularly a kind of split filling system of shield machine that starts.
Background technology
The excavation of subway tunnel generally has two kinds of patterns, and a kind of mode is Mining Method, and another mode is shield method.If the subway tunnel of construction is in complex geologic conditions and the intensive situation of above ground structure, be generally to adopt shield construction tunnel.Shield method is a kind of construction method of carrying out tunnel entirety driving with shield machine and corollary equipment thereof.Shield launching is a series of set-up procedures before shield machine construction.First, be at the end in pre-driving tunnel excavation shield structure well, the length of shield structure well generally will reach 80-100 rice, then, shield machine entirety is put into shield structure well, last, starts to carry out tunneling construction.When in the limited situation of construction environment, neighboring buildings is intensive, and shield structure well length cannot meet the construction requirement that normally starts, and causing shield machine to carry filling system cannot normally use, and the space between moulding tunnel and the soil body can not be filled in time.
Summary of the invention
The utility model provides a kind of split shield machine filling system that starts, and has solved shield machine and has carried the technical problem that filling system cannot normally use.
The utility model is to solve by the following technical programs above technical problem:
A kind of split shield machine filling system that starts, comprise moulding tunnel 1 and shield structure well 2, be provided with shield machine head 3 at the front end in moulding tunnel 1, be provided with dregs feed belt 4 and slag case 5 at the rear side of shield machine head 3, in shield structure well 2, be provided with filling system 8, filling system 8 is connected together by slip casting transfer pipeline 7 and the shield machine head slip casting outlet 6 on shield machine head 3, be provided with on the ground slurries mixing system 12 and slurry feeding pump 10, the outlet of slurry feeding pump 10 is connected together by slurries transfer pipeline 9 and filling system 8, the outlet of slurries mixing system 12 and the entrance of slurry feeding pump 10 are connected together.
On slurry feeding pump 10, be connected with slurries transport control system 11.
The utility model, by increase filling system in shield structure well shaft bottom, has been realized normally carrying out that shield machine split is started and constructed, and the space between moulding tunnel and the soil body is filled in time, has avoided the sinking of ground at During Initial Stage Construction.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is elaborated:
A kind of split shield machine filling system that starts, comprise moulding tunnel 1 and shield structure well 2, be provided with shield machine head 3 at the front end in moulding tunnel 1, be provided with dregs feed belt 4 and slag case 5 at the rear side of shield machine head 3, in shield structure well 2, be provided with filling system 8, filling system 8 is connected together by slip casting transfer pipeline 7 and the shield machine head slip casting outlet 6 on shield machine head 3, be provided with on the ground slurries mixing system 12 and slurry feeding pump 10, the outlet of slurry feeding pump 10 is connected together by slurries transfer pipeline 9 and filling system 8, the outlet of slurries mixing system 12 and the entrance of slurry feeding pump 10 are connected together.
On slurry feeding pump 10, be connected with slurries transport control system 11.
Start shield machine filling system construction of split is divided into following step: first, and mixing grouting serous fluid in slurries mixing system 12; Then, utilize slurry feeding pump 10 by slurries transfer pipeline 9, the good slurries of mixing to be delivered in filling system 8; Finally, filling system 8 is injected into slurries the gap of moulding tunnel 1 and the soil body from shield machine head slip casting outlet 6 by grouting pipeline 7, thereby completes filling slip casting.
Claims (2)
1. the split shield machine filling system that starts, comprise moulding tunnel (1) and shield structure well (2), be provided with shield machine head (3) at the front end of moulding tunnel (1), be provided with dregs feed belt (4) and slag case (5) at the rear side of shield machine head (3), it is characterized in that, in shield structure well (2), be provided with filling system (8), filling system (8) is connected together by slip casting transfer pipeline (7) and the shield machine head slip casting outlet (6) on shield machine head (3), be provided with on the ground slurries mixing system (12) and slurry feeding pump (10), the outlet of slurry feeding pump (10) is connected together by slurries transfer pipeline (9) and filling system (8), the entrance of the outlet of slurries mixing system (12) and slurry feeding pump (10) is connected together.
2. a kind of split according to claim 1 shield machine filling system that starts, is characterized in that, is connected with slurries transport control system (11) on slurry feeding pump (10).
