Problems solved by technology

[0002] At present, in the field of large-scale tunnel construction, shield machines are mostly used for tunnel construction. In the process of shield machine construction, the traditional construction method is that the shield machine excavates a section, and then the tunnel battery car transports the segment to the trolley. position, until all the segments on the tunnel battery car are hoisted, then the tunnel battery car is driven to the excavation opening, and then the shield machine is excavated, and the battery car is used for soil transportation. This construction method cannot be carried out simultaneously with shield machine excavation and hoisting. Low construction efficiency

Embodiment 1

[0032]Such asFigure 1 - Figure 5As shown in the present embodiment, a shield construction system includes a trolley 5 and a tunnel battery vehicle 6, and there are two trust rails 10 and tunnel according to the tunnel 4, and the tunnel battery track 11 is located in two tables. Between the vehicle orbital 10, the trolley 5 is disposed on two trolley tracks 10, and the tunnel battery vehicle 6 is disposed on the tunnel battery trail 11, and the front of the trolley 5 is open, and the front side of the trolley 5 has an opening, and also The first square wood unit, a top support unit, and a cantilever unit are included, and the first square wood unit is disposed on the tablet 7 of the tunnel battery vehicle 6, and the first square wood unit includes two first square wood 2, two first squares. The wood 2 is distributed in the front-rear direction and can support the tubular set, and the top support unit is disposed between two first square wood 2, and the top support unit includes the l...

Embodiment 2

[0042]The present embodiment has been further defined on the basis of the first embodiment, and the tubular group includes two and more tubular sheets 1, two and more tubes 1 longitudinal distribution, adjacent two tubes The sheet 1, and the lower tubes 1 are placed on two second square wood 3, and the two second square wood 3 supports the upper tubular sheet 1, in particular, the number of tubes 1 contained in the tube set is performed according to the actual situation. Set, for example, a shield machine having an outer diameter of 6.28 m, the outer diameter of the tube 1 is 6m, the inner diameter is 5.4m, width is 1.2m, in the specific use, set the flat plate 7 on the tunnel battery car 6, first square wood unit Both the cantilever unit, the top support unit, and the tubular sets are two, the plate 7, the first square wood unit, the cantilever unit, the top support unit, and the tube set one by one.

Embodiment 3

[0044]The present embodiment has been further defined on the basis of the first embodiment, and the present embodiment provides a shield construction method, using a shield construction system, including the following steps:

[0045]A. Place the tube set on the first square wood unit;

[0046]B, use tunnel battery cars 6 transport the tubular port from the front side of the trolley 5;

[0047]C, start the top support unit, bring the tube set from the first square wood 2, remove the first square wood 2;

[0048]D, the tunnel battery car 6 continues to move until the tube set is located above the cantilever unit;

[0049]E, the top support unit drops, the tube set is placed on the cantilever unit, and the tunnel battery car moves from the trolley 5 to the outsoile.

Abstract

The invention discloses a shield construction system and a shield construction method. The shield construction system comprises a trolley and a tunnel battery car, wherein the trolley is arranged on two trolley tracks, the tunnel battery car is arranged on a tunnel battery car track, the front part of the trolley is open, and the front side of the bottom wall of the trolley is provided with an opening. The shield construction system further comprises a first square wood unit, a top supporting unit and a cantilever unit, wherein the first square wood unit is arranged on a flat plate of the tunnel battery car, the first square wood unit comprises two first square woods, the two first square woods are distributed in the front-back direction and can support a pipe piece group, the top supporting unit comprises a lifting device group and a component, the component is connected with the output end of the lifting device group, the lifting device group can drive the component to move up and down, the cantilever unit is arranged on the trolley, the cantilever unit comprises two cantilever groups, the two cantilever groups are respectively located on the left side and the right side of the opening, and the two cantilever groups can support the pipe piece group. By using the system and the construction method, the efficiency of shield construction can be improved.

Description

Technical field[0001]The present invention relates to the technical field of tunneling construction engineering, and specific to a shield construction system and a shield construction method.Background technique[0002]At present, in the field of large tunnel construction, there are mostly used shield machines for tunnel construction. In the process of shield machine construction, traditional construction methods are shield machine trains, and then transport the tubes to the trolley by tunnel battery vehicles. Location, until all the tubes on the tunnel battery car are all hoisted, then the tunnel battery car is opened to the outbound mouth, then the shield machine is tunnen, and the battery car is used to carry out soil, this construction shield machine drum and hoisting cannot be carried out at the same time. The construction efficiency is low.Inventive content[0003]In view of the deficiencies in the prior art, the present invention provides a shield construction system and a shield...
