Embodiment Construction

[0034] Such as figure 1 Shown is a method for reversely hauling trolleys in a tunnel, the method of the present invention comprises the following steps:

[0035] Step 1. Separation of the trolley: the trolley is split into multiple car bodies 3 in the tunnel, and the multiple car bodies 3 are arranged on the trolley guide rail 7-1 in sequence;

[0036] In this embodiment, the number of car bodies 3 is 6, and the 6 car bodies 3 are arranged on the trolley guide rail 7-1 in sequence, and the ones arranged in sequence along the direction of the receiving wellhead of the shield machine to the starting wellhead of the shield machine are number one respectively. Hull, No. 2, No. 3, No. 4, No. 5, and No. 6.

[0037] Step 2. Reinforcement of the car body: if figure 2 As shown, a first reinforcement rod 4-1 and a second reinforcement rod 4-2 are installed between the bottom of the car body 3;

[0038] In actual use, when the car body 3 needs to be assembled on the segment car 1, si...

Abstract

The invention discloses a method for reversely hauling a trolley in a tunnel. The method includes: 1. separation of the trolley; 2. reinforcement of the vehicle body; 3. reinforcement of the segment vehicle; 5. Assembly of the car body and segment car; 6. Reverse hauling of the car body; 7. Multiple cycles of steps 4 to 6 until the reverse hauling of the trolley in the tunnel is realized. The method of the invention has simple process and high construction safety, solves the problem that the trolley cannot be separated from and hoisted out from the narrow shield receiving wellhead, makes full use of existing equipment in the tunnel, saves resources, and reduces construction costs.

Description

technical field [0001] The invention belongs to the technical field of subway tunnel construction, and in particular relates to a method for reversely dragging a trolley in a tunnel. Background technique [0002] After the construction of the shield machine is completed, the shield machine and the trolley are disassembled at the receiving wellhead of the shield machine, and then separated from the receiving wellhead of the shield machine in turn and hoisted out. However, in the actual construction process, often due to the area of ​​the construction site Due to the limitation, the receiving wellhead of the shield tunneling machine is very narrow, which leads to the inability of the trolley to be separated from the receiving wellhead of the shield tunneling machine and hoisted out. The starting wellhead is separated and hoisted out. At this time, the trolley has been pulled by the shield machine to the position of the receiving wellhead of the shield machine. The trolley is ...
