Problems solved by technology

[0003] When the above method is used to construct the tunnel, slurry often occurs. At present, the treatment measure taken after the ground slurry in the shield construction area is to manually remove the ground slurry. However, the disadvantage of this construction method is that it requires a lot of labor. Therefore, it is necessary to Invent a more efficient tool to clear the floor of the slurry

Embodiment 1

[0031] see figure 1 , there is a leg 2 under the base 1, and there are two legs; a column 4 is hinged and fixed on the upper surface of the base 1 through a bearing, and the bearing is a ball bearing, so that the column 4 can be parallel to the circumferential direction of the base 1 on the base 1 Rotate freely on the ground, one end of the first connecting arm 6 is hinged and fixed on the top of the column 4 through the first rotating shaft 16; the other end of the first connecting arm 6 is hinged with one end of the second connecting arm 9 through the second rotating shaft 7, and the second connection The other end of arm 9 is hinged with vertical bar 12 by connecting shaft 10, and vertical bar 12 keeps vertical ground downward all the time; The end is connected with the first connecting arm 6, the fixed end of the second pneumatic cylinder 8 is connected with the first connecting arm 6, and the moving end of the second pneumatic cylinder 8 is hinged with the second connecti...

Embodiment 2

[0033] see figure 2 The suction nozzle 13 provided by the present invention includes a side nozzle 14 and a vacuum suction cup 15. The side nozzle 14 is a small opening pipe opened on the side wall of the suction pipe 3. The nozzle direction of the side nozzle 14 is downward, and the side nozzle 14 Two and symmetrically arranged on both sides of the suction pipe 3, the vacuum suction cup 15 is a trumpet opening, the vacuum suction cup 15 is a soft suction cup, the vacuum suction cup 15 is arranged on the top of the side nozzle 14, and can be integrally coated on the outside of the side nozzle 14, When the side nozzle 14 is sucking air, the bell-shaped opening will be deformed under the influence of negative pressure. After the negative pressure is formed, the mud level can be effectively lifted and sealed. At this time, the port of the suction pipe 3 will not be in contact with the mud. Air leakage occurs, and the mud is sucked into the suction pipe 3 more efficiently and qui...

Embodiment 3

[0035] Taking the cleaning tool provided by the present invention to remove the slurry on the ground in the shield tunneling area as an example, the method for cleaning the slurry is described.

[0036] During the construction of the shield machine, if slurry occurs on the ground, firstly, the removal tool provided by the present invention is placed in a clean place near the area to be cleaned of slurry, and the movement of the first pneumatic cylinder 5 and the second pneumatic cylinder 8 is adjusted to drive the first pneumatic cylinder 5 and the second pneumatic cylinder 8 respectively. The connecting arm 6 and the second connecting arm 9 rotate, so that the horizontal position and the vertical position of the suction pipe 3 fixed on the vertical rod 12 are moved, and finally ensure that one end of the suction pipe 3 fixed on the vertical rod 12 is placed in the place to be removed. above the area;

[0037] Then adopt the vacuum pump to inhale the side nozzle 14. After effe...

Abstract

The invention belongs to the technical field of civil engineering construction, and relates to a tool and a method for removing oozing slurry on the ground of a shield construction area. The tool comprises a stand column, a mechanical arm, a movement mechanism and a suction tube, wherein the mechanical arm is fixed on the stand column, the movement mechanism is connected with the mechanical arm todrive the mechanical arm to rotate around the stand column, the suction tube is erected on the mechanical arm, a suction nozzle is arranged at one end of the suction tube and is always perpendicularto the ground, the suction nozzle comprises a side tube opening formed at one end of the suction tube and a vacuum suction cup, the side tube opening is formed in a lower small pipeline on the suctiontube and communicates with the interior of the suction tube, the vacuum suction cup is located above the side tube opening and completely wraps the side tube opening, the vacuum suction cup is provided with a horn type opening, and the horn type opening completely covers the side tube opening. The tool is simple in structure, convenient to operate and high in oozing slurry removal efficiency, theconstruction period can be shortened through automatic operation, the labor cost is saved, and the construction method is more environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of civil engineering construction, and relates to a tool and a method for removing slurry from the ground, in particular to a tool and a method for removing slurry from the ground in a shield construction area. Background technique [0002] The shield tunnel construction method refers to the use of a shield machine to control the excavation surface and surrounding rock from collapse and instability accidents, on the one hand to carry out tunnel excavation and slag discharge, and to complete the assembly of segments in the machine to form lining and implement A method of constructing a tunnel without disturbing the surrounding rock by grouting behind the wall. [0003] When the above method is used to construct the tunnel, slurry often occurs. At present, the treatment measure taken after the ground slurry in the shield construction area is to manually remove the ground slurry. However, the disadvantage of th...
