Problems solved by technology

[0003] At present, in shield construction, the requirements for the construction technology of the supporting mud are getting higher and higher. After all, it is related to the safety of the staff. However, the existing construction devices still have defects in the mixing of the supporting mud. Thoroughly, the hidden danger to the safety of the staff is still relatively large. Therefore, it is urgent to design the construction technology of support mud for settlement control of shield tunneling to solve the above problems

Embodiment 1

[0026] refer to Figure 1-2 , the construction process of supporting mud for shield construction settlement control, including a box body 1, the outer wall of one end of the box body 1 is connected with a water tank 3 by bolts, and the top of the outer wall around the box body 1 is connected with a water guide groove 5 by bolts, and the structure of the water guide groove 5 A water delivery pipe is welded between the middle position of the outer bottom of one end and the top outer wall of the water tank 3, and the middle position of the outer bottom wall of the tank body 1 is connected with a rotating motor 14 through a bolt, and one end of the output shaft of the rotating motor 14 is connected with a main shaft 10 through a bolt, and the main shaft 10 The outer wall of the circumference of the box is welded with connecting columns 13 equidistantly distributed, and the outer wall of the other end of the connecting column 13 is welded with a square frame, and the inner walls aro...

Embodiment 2

[0034] refer to image 3 , the construction process of supporting mud for shield construction settlement control. Compared with Embodiment 1, this embodiment replaces the connecting columns 13 with equidistantly distributed springs 18 .

[0035] Working principle: When in use, when the stirring net 9 is stirring and mixing the raw materials in the box body 1, the stirring may be uneven. At this time, by replacing the connecting column 13 with a spring 18, the main shaft 10 can be rotated. , the irregular swing force is applied to the stirring net 9, so that the effect of stirring is better.

Abstract

The invention discloses a supporting mud construction process for settlement control in shield construction. The process comprises a box body, a water tank is fixedly connected to the outer wall of one end of the box body, a water guiding groove is fixedly connected to the top of the outer wall of the periphery of the box body, and a water conveying pipe is fixedly connected between the middle of the outer bottom of one end of the water guiding groove and the outer wall of the top of the water tank; and a rotating motor is fixedly connected to the middle of the outer wall of the bottom of the box body, a main shaft is fixedly connected to one end of an output shaft of the rotating motor, connecting columns distributed at equal intervals are fixedly connected to the circumferential outer wall of the main shaft, and square frames are fixedly connected to the outer walls of the other ends of the connecting columns. Blending of supporting mud and next construction are achieved, water in the water tank is pumped into the water guiding groove through a water pump and then flows out of a water outlet head, the water in the water tank can be heated through a heating bar, large impurities in supporting mud raw materials can be partially intercepted through a filter screen, and a pull plate and the filter screen can be pulled out by pulling a handle.

Description

technical field [0001] The invention relates to the technical field of shield tunnel construction, in particular to a construction technique of supporting mud for settlement control of shield tunnel construction. Background technique [0002] The very important auxiliary means in shield construction is behind-the-wall grouting construction, which develops very rapidly. In grouting construction, geological conditions are decisive factors for the selection of grouting materials, and grouting volume, grouting pressure and grouting Speed ​​is the key parameter in grouting construction, and proper grouting volume and pressure are the guarantees of grouting quality. [0003] At present, in shield construction, the requirements for the construction technology of the supporting mud are getting higher and higher. After all, it is related to the safety of the staff. However, the existing construction devices still have defects in the mixing of the supporting mud. Thoroughly, the hidd...
