Detailed Description
The features of the present invention and other related features are described in further detail below by way of example in conjunction with the accompanying drawings to facilitate understanding by those skilled in the art:
as shown in fig. 1-2, the symbols 1-7 in the figures are respectively represented as: the shield machine comprises a shield body 1, a temporary support 2, steel rail rollers 3, a support guide rail 4, a station passing rail 5, a station structure 6 and a channel steel sleeper 7.
Example (b): as shown in fig. 1, the simple support structure for the shield machine idle pushing in the present embodiment is used for an idle pushing station of a shield body 1 of the shield machine, where the idle pushing station refers to: the shield body 1 of the shield machine is pushed to pass through the station range of the station structure 6 in an idle state, so that the steps of hanging and dismantling the shield body 1 of the shield machine are avoided.
As shown in fig. 1, the shield body 1 of the shield machine in the present embodiment is a circular shield body, and a support structure and a station passing rail 5 are erected below the circular shield body to realize the air-pushing station passing of the shield body 1.
Specifically, as shown in fig. 1, two station passing rails 5 are arranged in the station structure 6, and the two station passing rails 5 are arranged to extend in the pushing direction of the shield body 1. Temporary supports 2 serving as bearing support members are arranged on two sides of the bottom of a shield body 1 of the shield machine, and the temporary supports 2 are welded and fixed on the shield body 1 of the shield machine and respectively correspond to the positions of two station passing rails 5. The bottom of the temporary support 2 is provided with a steel rail roller 3, and the steel rail roller 3 is erected on the station crossing rail 5 and can roll along the station crossing rail 5, so that the shield body 1 of the shield machine is pushed on the station crossing rail 5 along the pushing direction of the shield machine.
As shown in fig. 1 and 2, two support rails 4 are further disposed at the bottom of the shield body 1, and the two support rails 4 are disposed inside the two temporary supports 2 and extend along the pushing direction of the shield body 1. The support guide rail 4 is used for supporting the shield body 1 of the shield machine so as to ensure the stability of the shield machine in the process of idle pushing and station passing. In the present embodiment, the distance between the two support rails 4 is sufficient for the bottom part of the shield body 1 of the shield machine with a circular structure to be partially supported between the two support rails 4, so as to ensure that the support rails 4 can effectively support the shield body 1 of the shield machine.
As shown in fig. 2, two support rails 4 are mounted on the channel steel tie 7, and the support rails 4 can be firmly fixed on the channel steel tie 7 by means of welding pressure plates between the two. In this embodiment, in order to improve the structural stability of the two support rails 4, the two support rails 4 can be made to form an integral structure by welding the transverse channel steel between the two support rails 4, so as to ensure that the support rails 4 always ensure the structural stability in the process of the shield body 1 of the shield machine passing through the station, thereby effectively supporting the shield body 1 of the shield machine.
The temporary support 2 in this embodiment may be made of a steel member by welding and reinforcing, for example, a member commonly used for construction such as i-steel, channel steel, and a rail. As shown in fig. 1, the temporary support 2 in this embodiment is of an H-shaped structure, and has good structural strength and stability.
In the embodiment, in specific implementation: hole sites can be uniformly arranged on the station passing rail 5 at intervals according to a certain distance, the hole sites can be arranged at the web plate position of the station passing rail 5, the station passing rail 5 is fixed at the design position of the station passing rail by matching with ground anchor fixing pieces or other types of fixing pieces, and the stability of the shield body 1 of the shield machine in the process of idle pushing the station passing rail is ensured.
Two groups of temporary supports 2 and steel rail rollers 3 are arranged at intervals on the front side and the rear side of the bottom of the shield body 1 of the shield machine along the pushing direction of the shield body 1 of the shield machine, and the steel rail rollers 3 on the two groups of temporary supports 2 are all erected on a station passing track 5 so as to ensure the stability of the shield body 1 in the idle pushing station passing process.
When in use, after the notch of the shield body 1 of the shield machine enters a station for a certain distance, a first group of temporary supports 2 with steel rail rollers 3 are welded on the shield body 1 of the shield machine according to the structure shown in figure 1; when the middle shield enters a station, a second group of temporary supports 2 with steel rail rollers 3 are welded at the position of a certain distance from the joint of the front shield and the middle shield to the shield tail. In general, the installation positions of the two groups of temporary supports 2 with the steel rail rollers 3 are subject to guarantee the front-back balance of the whole shield body 1 of the shield machine. After the installation is finished, the shield body 1 of the shield machine is pushed into the station range of the station structure 6 by a jack. After the station is empty-pushed, the temporary support 2 can be cut off from the shield body 1 of the shield machine, and the lower rail system can be detached for use when the station is empty-pushed again.
Although the conception and the embodiments of the present invention have been described in detail with reference to the drawings, those skilled in the art will recognize that various changes and modifications can be made therein without departing from the scope of the appended claims, and therefore, the description thereof is not repeated herein.
