Description

Technical Field

[0001] The invention relates to the field of tunnel construction, in particular to a device for transporting assembled cross-shaped partitions inside an electric shield tunnel. Background Art

[0002] In order to meet the requirements of functional zoning of cable tunnels for cable insertion and later convenient operation, after the shield tunnel is penetrated, cross partitions need to be constructed inside the tunnel formed by the shield. At present, cross partitions of power tunnels usually adopt the form of fully cast-in-place concrete structure. Precast concrete structure is also used, but it is less used. In addition, the existing precast cross partitions generally only have some components precast, not fully precast.

[0003] For example, the publication number CN115075834A provides a cross-section structure and construction method for a power tunnel, which uses a partition designed in the form of a prefabricated concrete structure. Based on the scheme analysis, the following conclusions are drawn:

[0004] 1. The cross partition components of this scheme are partially prefabricated and partially built, and the process is relatively complicated;

[0005] 2. The prefabricated components of the cross partition of this scheme are difficult to transport and install in the shield tunnel;

[0006] 3. When ordinary prefabricated transverse diaphragm components are installed and fixed in the shield tunnel, in order to ensure the stability of the force on the transverse diaphragm components, the transverse diaphragm components need to be firmly fixed to the segments. Usually, holes are drilled and reinforcement is embedded in the tunnel segments, or steel plates are embedded in the shield segments and diaphragm components in advance, and then welded or bolted. Drilling holes and reinforcement in the tunnel segments will destroy the integrity of the segments, and dust is easily generated during the drilling process, which may have a certain impact on the tunnel environment. After drilling holes in the segments, there may be safety risks such as leakage or even cracking of the segments.

[0007] The method of pre-embedding steel plates on shield segments and partition components, and then welding or bolting them together, can easily cause a certain degree of damage to the health of construction workers in tunnels with poor ventilation. Although the bolt connection method will not affect the health of construction workers, the process is more complicated and can easily lead to slow construction progress.

[0008] Therefore, in order to solve the above problems, a device for transporting assembled cross-shaped partitions inside a power shield tunnel is proposed. Summary of the invention

In order to facilitate transportation and installation in the pipe segment, the No. 1 baffle assembly as a whole and the No. 2 baffle assembly as a whole are designed to be in the shape of a parallelogram, the support plate 2 and the T-shaped plate 16 are each in the shape of a parallelogram, the shortest diagonal of the parallelogram is perpendicular to the axis of the pipe segment, and the shortest diagonal of the support plate 2 is smaller than the diameter of the pipe segment, and the longest diagonal length of the support plate 2 is greater than the diameter of the pipe segment; as Fig.10 As shown, when the No. 1 baffle assembly or the No. 2 baffle assembly is transported in the pipe segment, after being transported to the designated position, the No. 1 baffle assembly or the No. 2 baffle assembly is rotated, and the state is as follows Fig.11 As shown, it is convenient for migration, installation and disassembly within the segment.

[0050] Working principle: The specific implementation of the No. 1 partition unit is that after the tunnel is excavated, the pipe segments are laid, and the pipe segments support the earthwork in the tunnel. The No. 1 partition unit is set in the pipe segment for laying cables with various functions. The No. 1 partition unit is laid at intervals of 6 meters in the pipe segment; the bracket 1 is erected in the pipe segment, and the support plate 4 is erected above the bracket 1. When the support plate 4 is installed, one end of the clamping part 5 is aligned with one side of the clamping slot 6, and then the clamping part 5 is pushed horizontally into the clamping slot 6 so that the two ends of the clamping part 5 are aligned with the two sides of the clamping slot 6. The upper and lower parts cooperate to divide the pipe segment into multiple areas to achieve classified laying of cables with different functions; at the same time, the No. 1 partition unit is a completely prefabricated design, which is convenient for installation, as well as for later movement and disassembly, which is conducive to the smooth progress of construction operations. Moreover, the upper and lower parts are designed separately, which is convenient and fast to manufacture. When transported by vehicles, they can also be classified and stacked, which is convenient for loading and transportation;

[0051] When the cable is being laid, the dragging of the cable will rub the support plate 4. At this time, there is a tendency for the clamping part 5 to slide away from the clamping slot 6. Therefore, after the vertical plate is installed on the support plate 2, the through hole 7 on the clamping part 5 is aligned with the through hole 7 in the clamping slot 6. Then the arc rod 8 is passed through the through hole 7. The arc rod 8 fixes the support plate 4 and the support plate 2, that is, the relative movement tendency of the support plate 4 along the axial direction of the pipe segment is stabilized to ensure that the upper part can be stably installed on the lower part.

[0052] After the upper and lower parts are fixed, the No. 1 partition assembly is then stabilized as a whole in the tunnel, that is, the No. 1 partition assembly is stabilized on the pipe segment to prevent the No. 1 partition assembly from being displaced in the pipe segment. By rotating the sleeve 10, the sleeve 10 can push the push rod 9 outward. At this time, the two push rods 9 connected to the same sleeve 10 are separated from each other, one of the push rods 9 is pressed against the arc rod 8, and the other push rod 9 is pressed against the pipe segment. The transmission of the extrusion force can stabilize the No. 1 partition assembly as a whole in the pipe segment.

[0053] The threaded barrel 12 is rotated, and the threaded barrel 12 pushes the limiting rod 11 to the outside, that is, the two limiting rods 11 connected to the same threaded barrel 12 are separated from each other and pressed against each other on the arc-shaped rod 8 close to the outside, so that the two adjacent No. 1 baffle assemblies are stabilized, so that the multiple No. 1 baffle assemblies in the pipe segment are connected into a whole, which is conducive to the stability of the No. 1 baffle assemblies;

[0054] After the support plate 4 is installed, the bolt 15 is rotated so that the bolt 15 presses against the inner top of the pipe segment, which stabilizes the upper part and further stabilizes the No. 1 partition assembly as a whole.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
