Embodiment 1

[0031] The present invention will be further described below in conjunction with accompanying drawing:

[0032] As shown in the figure, 1 is the cutter head, 2 is the front shield, 3 is the middle shield, 4 is the back shield, 5 is the connecting bridge, 6 is 1 # Trolley, 7 is 2 # trolley, 8 is gas pipeline, 9 is water pipeline, 10 is wire harness, 11 is 5 # Cable host on the trolley, 12 is 3 # Trolley, 13 is 4 # Trolley, 14 is 5 # Trolley, 15 are hoisting wellheads, and 16 are unearthed mouths.

[0033] Detailed construction method of the present invention is:

[0034] ① Underground cleaning site

[0035] ②The starting base is assembled in the well and the track is laid

[0036] Install the starting bracket before laying the track. After installing the bracket, place the waste segment on it, and then lay two left and right rails of 2080mm and 900mm gauge on the segment according to the center line of the tunnel to the bottom of the portal.

[0037] A winch is installe...

Abstract

The invention discloses a shield tunneling machine split starting construction method and belongs to the technical field of building construction. The method comprises the following steps: (1) cleaning an underground site, (2) starting base seat underground assembling and laying rails, (3) moving a first trolley and a second trolley underground and moving the first trolley and the second trolley backward, (4) moving a duct piece cart underground, (5) moving a connecting bridge and a spiral conveyor underground in a hoisting mode, and moving the connecting bridge and the spiral conveyor backward, (6) moving a starting table underground, smear ing lubricating grease, moving a cutter disk and a shield body underground and locating and assembling the cutter disk and the shield body, (7) assembling, (8) starting trying tunneling, (9) restoring to normal shield tunneling. The method has the advantages of effectively solving the problem that a shield tunneling machine cannot be operated and run normally for being restricted by the actual environment of a shield tunneling staring operation shaft on a construction site, greatly improving construction efficiency, saving construction cost, and reducing construction difficulty.

Description

technical field [0001] The invention belongs to the technical field of building construction. Background technique [0002] At present, shield construction technology has been widely used in transportation, hydropower and other engineering fields. The shield construction section is generally divided into three parts: the starting operation well of the shield machine, the shield section and the shield receiving operation well. According to the total length of the shield machine (80m) and the needs of excavation (well), the origination of the shield machine generally requires an origination shaft length of about 120m. In order to save costs and facilitate construction, one end of a structure such as a station is usually used as the starting working shaft of the shield machine. However, when the length of the building to be used as the starting working shaft of the shield machine is less than the total length of the shield machine, and the construction must be carried out as ...
