Description
Technical Field
The invention belongs to the technical field of mechanical equipment special for mounting a tunnel intermediate wall, particularly relates to a prefabricated intermediate wall mounting device for a shield tunnel, belongs to shield tunnel construction equipment, and is particularly suitable for the construction of a shield tunnel with an oversized diameter.
Background
The arrangement of the intermediate wall in the large-diameter shield tunnel realizes single-hole double-line operation, and is a great technical innovation in rail transit engineering. However, it is a difficult problem to construct the intermediate wall in a relatively narrow tunnel space. According to the construction method, construction symptoms and key points are found out through simulation calculation and analysis in combination with engineering practice, a corresponding construction method is made, a prefabricated intermediate wall mounting device is specially developed, the prefabricated intermediate wall can be quickly assembled in a narrow tunnel space, the construction quality is improved, the construction period is shortened, and ideal social and economic benefits are obtained. Adopt the door type structure, can supply the advantage that engineering vehicle passes through.
In the shield tunnel construction process, the construction steps of the intermediate wall are relatively complicated, and the common method is to erect a common template for the construction of cast-in-place concrete. However, the traditional scheme has the problems that the construction speed is slow, the space in the tunnel is occupied when the template is erected, and the engineering vehicle is difficult to pass. Or, some construction units simply change the templates, but the limiting and anti-rollover stability of the intermediate wall template trolley and other aspects are not fully considered, so that the problem is still large, and the intermediate wall construction of the shield tunnel is difficult to adapt.
The prefabricated intermediate wall of the related art generally adopts a cast-in-place concrete structure, and the prefabricated intermediate wall is connected with a tunnel segment in a bar planting mode. This design has the following problems: firstly, the height of the prefabricated intermediate wall is larger, generally more than 6m, and the thickness is smaller and generally not more than 500mm, so that the construction of the vertical mold by adopting a cast-in-place mode is very inconvenient, and the construction speed is slower; secondly, the concrete pouring quality at the joint of the prefabricated intermediate wall and the tunnel segment is difficult to ensure; thirdly, the prefabricated intermediate wall and the tunnel segment are fixed through embedded steel bars, the prefabricated intermediate wall limits the vertical deformation of the tunnel segment structure, and the design stress and deformation mode of the tunnel segment structure are changed; fourthly along the prefabricated well partition wall structure axis direction in tunnel, the segmentation of prefabricated well partition wall is longer, about 20m usually, and the tunnel segment width is between 1 ~ 1.5m, and the existence of prefabricated well partition wall has increased the rigidity of being connected between the adjacent tunnel segment like this, has violated the original purpose of the design of flexible connection between the tunnel segment, and is unfavorable to the antidetonation of the prefabricated well partition wall structure in tunnel.
Accordingly, those skilled in the art have endeavored to develop a novel structure of the partition wall in the tunnel. The invention with the application number of 20091024607.7 discloses a prefabricated intermediate wall structure, the intermediate wall is a reinforced concrete prefabricated part extending along the length direction of a tunnel, a tunnel segment is connected with the intermediate wall through a clamping groove, the clamping groove is arranged on the inner side of the tunnel segment and is provided with a groove with a downward opening for accommodating the upper end part of the intermediate wall, a roadway plate is connected with the intermediate wall through a base, the base is arranged at the center of the roadway plate and is provided with a groove with an upward opening for accommodating the lower end part of the intermediate wall, an inserting rib is reserved at the lower end of the intermediate wall to be fixed with the base, concavo-convex tenons are arranged between the intermediate walls, butyronitrile cork rubber is adhered between the tenons, and the periphery is embedded with elastic fireproof sealant. This structure facilitates construction while saving construction time, but puts new demands on installation. The mid-board has heavier dead weight, large plane size, thinner components and higher installation height. The splicing machine is required to occupy only half of the pavement in the circular tunnel for operation, the splicing machine is required to be capable of performing fine adjustment operation in all directions, and the self weight of the splicing machine is required to be as light as possible. In addition, the splicing machine is electrically driven, and the power of the splicing machine is required to be not more than 60kw under the condition of meeting the use function in consideration of the problems of long tunnel line and voltage drop caused by low-voltage power supply. The current special installation equipment for the middle partition wall structure generally has the defects of complex structural design and relatively poor operation controllability, and has higher requirements on construction operation skills of workers.
