Embodiment Construction

[0023] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0024] figure 1 A schematic diagram of Embodiment 1 of the support rod assembly according to the present invention is shown. As shown in the figure, the support rod assembly in this embodiment includes: a main pipe 10 and a support rod 20, and the support rod 20 is telescopically arranged on the main pipe 10 the end of. The support rod assembly of this embodiment adjusts the position of the support rod 20 in the main pipe 10, and then adjusts the length of the support rod assembly, so that the support rod assembly can adapt to different supports or tunnels, and the support rod assembly is supported on the support or tunnel. It provides additional bearing capacity for the bracket, solves the p...

Abstract

The invention provides a support rod component. The support rod component comprises a main pipe, a support rod and end portions which are arranged on the main pipe in an extensible mode. The support rod component are supported in a support or a tunnel, provides extra bearing force for the support, solves the problem that the bearing force of the support is unstable in a period of changing the support or repairing an old tunnel, plays a temporary supporting role for the support or the tunnel, supports a deformed support and enables the support to resile.

Description

technical field [0001] The invention relates to the technical field of support, in particular to a support rod assembly. Background technique [0002] In the prior art, there are a large number of supports in the tunnel, and many supports are not properly used due to the overload of cables placed in the later period or the drop-off of the embedded parts of the supports from the tunnel body due to the excessive instantaneous load during the installation of the joints during construction. Causes deformation, cracking and other load-bearing failures of the bracket, reduces the bearing capacity of the bracket, and brings great safety hazards to the operation of the cable. When replacing these brackets, the replacement is very cumbersome due to insufficient bearing capacity. Now In the prior art, there is no device that can provide extra bearing capacity for the bracket well, and it is extremely difficult for the bracket to return to its original shape. Contents of the inventio...
