Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] Such as Figure 1 to Figure 4 Shown: a universal device for the power head of the MJS reinforcement equipment for the subway communication channel, including the movable frame 1, the power head 2, the bearing and the bearing seat 3, the movable frame hinge 4, the bracket 5, the fixed frame 6, the earring 7, and the slider 8. Single-acting oil cylinder 9.

[0019] The power head 2 is placed on the movable frame 1, and the movable frame 1 is rotatably connected to the fixed frame 6 through the bearing and the bearing seat 3, so that the power head 2 can be adjusted at any angle from -30° to 70°; the fixed frame and the movable frame A movable frame fixing locking device is installed between them, which is used for locking after the power head 2 adjusts the angle.

[0020] The movable frame fixed locking device is made up of movable frame hinge 4,...

Abstract

The invention relates to a universal device of a subway interconnecting passage MJS reinforcing device power head. The universal device comprises a movable frame, a power head, a fixed frame, and a movable frame fixed locking device. The universal device is characterized in that the power head is arranged on the movable frame, the movable frame is rotatably connected with the fixed frame through a bearing and a bearing pedestal 3, so that the power head can be adjusted in any angle in the range of -30 DEG to 70 DEG. The movable frame fixed locking device is arranged between the fixed frame and the movable frame, and the movable frame fixed locking device is used for locking after angle adjustment of the power head 2. Through adding a universal structure frame on the rear of the power head, the power head can be adjusted in any angle in the range of -30 DEG to 70 DEG. After angle adjustment is completed, the power head is locked through a one-way cylinder added on a slideway and a strut on the rear end of a support. Aimed at part of relatively large tunnels, a lifting mechanism can be assembled on the lower part of the structure frame, and horizontal position of the device can be adjusted.

Description

technical field [0001] The patent of the present invention relates to an excavation and reinforcement construction device for subway tunnel communication channels in soft soil areas and strata rich in groundwater. Background technique [0002] At present, the excavation of the connecting channel is basically carried out by the freezing method. Since the freezing method has ground settlement in the thawing and settlement stage after excavation and a long period of time in the later period, it has a great impact on the structural settlement of the side channel, and the uneven settlement has a great impact on the connecting channel itself. The connection between the structure and the connecting channel and the tunnel structure is severely damaged, and settlement has become an irreversible common quality problem. Therefore, our company and the cooperative unit explored the method of cement-soil reinforcement for the soil using the MJS construction method in the tunnel to avoid t...
