Problems solved by technology

[0003] The use of the shield machine is often inseparable from the support mud, and the performance requirements of the support mud required by the shield machine in different environments are also different. During the construction process, it is a headache to easily change the performance of the support mud It not only delays the construction time, but also wastes a lot of money. Therefore, it is urgent to design a modified shield machine with support mud to solve the above problems.

Embodiment 1

[0027] refer to Figure 1-3 , a modified support mud for a shield machine, including a cylinder 1, a motor 17 is connected to the bottom of the inner wall of the cylinder 1 through bolts, and the output shaft of the motor 17 is connected to a base 16, and a circular groove 18 is welded around the bottom of the base 16 , and the top of the base 16 is connected to the transmission shaft 14, the two sides of the transmission shaft 14 are welded with blades 19, and a groove is opened on one side of the cylinder body 1, the inner wall of the groove is welded with the water inlet pipe 8, and the other end of the water inlet pipe 8 is connected to the circular groove 18 one side, and the bottom of the circular groove 18 is provided with a discharge port 9, and a discharge pipe 15 is welded on the inner wall of the discharge port 9.

[0028] Wherein, a blanking area 12 is provided on the top of the cylinder body 1, and an extrusion block 22 is movably connected to the inner wall of th...

Embodiment 2

[0035] refer to Figure 4 , a modified support mud for a shield machine. Compared with Embodiment 1, this embodiment has a vibrating plate 25 connected to one side of the blanking area 12 by bolts.

[0036] Working principle: When in use, when the support mud in the blanking area 12 drops slowly, the user vibrates the support mud in the blanking area 12 through the vibrating plate 25 to prevent the support mud from solidifying on the inner wall of the blanking area 12, thereby causing the device to Cannot carry out follow-up use, also simplifies the cleaning process of this device simultaneously, prolongs the service life of this device.

Abstract

The invention discloses modified supporting mud for a shield tunneling machine. The modified supporting mud comprises a barrel. An electric motor is fixedly connected to the bottom of the inner wall of the barrel, and an output shaft of the electric motor is connected with a base. A circular groove is fixedly connected to the periphery of the bottom of the base, a transmission shaft is connected to the top of the base, and blades are fixedly connected to the two sides of the transmission shaft correspondingly. A groove is formed in one side of the barrel, a water inlet pipe is fixedly connected to the inner wall of the groove, the other end of the water inlet pipe is connected to one side of the circular groove, a discharging opening is formed in the bottom of the circular groove, and a discharging pipe is fixedly connected to the inner wall of the discharging opening. According to the modified supporting mud, the supporting mud modification work can be effectively carried out, a user can add the supporting mud by himself according to parts on the device, the situation that due to the fact that too much or too little supporting mud is added, the expected effect is not achieved is avoided, a large amount of time and a large quantity of resources are saved, manual stirring is replaced, and the modification efficiency is improved on the premise that the effect is not affected.

Description

technical field [0001] The invention relates to the technical field of shield machines, in particular to a modified support mud for shield machines. Background technique [0002] The shield machine is a tunnel boring machine that uses the shield method. The construction method of the shield tunnel is that the tunnel boring machine builds (lays) the "shield" (referring to the supporting segment) of the tunnel while digging, which is different from the open construction. Internationally, the generalized shield machine can also be used in rock formations, but it is different from the open (non-shield method) tunnel boring machine. In our country, it is customary to call the tunnel boring machine used in soft ground as (narrowly defined) shield machine. [0003] The use of the shield machine is often inseparable from the support mud, and the performance requirements of the support mud required by the shield machine in different environments are also different. During the constr...
