Problems solved by technology

The main reasons for this are firstly that the technology in the early stage of construction is not particularly mature, and secondly that under normal circumstances the trains run in one direction, and the force on the catenary is also in one direction, causing the stressed anchor columns to break easily

Embodiment 1

[0030] Example 1, please refer to figure 1 , this embodiment discloses a catenary anchor post emergency repair method, including the following steps:

[0031] (1) Prepare for construction:

[0032] Transport the emergency materials to the accident site, assemble the emergency steel columns on site, determine the location of the original cable pit, and excavate the cable foundation pit.

[0033] (2) Install emergency steel columns:

[0034] aFirst install the base of the emergency steel column at the broken anchor column, then install the insulating plate between the base and the rail to ensure that the rail and the base are not connected, and finally assemble the emergency steel column;

[0035] b. Connect the wrist arm upside down on the rescue steel column;

[0036] (3) Install temporary stay wires:

[0037] a. Install the anchor plate, rod and wire in the original wire pit, and pay attention to the fastening when anchoring the wire, and in the direction of the force;

...

Embodiment 2

[0049] Embodiment 2, the present embodiment changes the step (3) in the previous embodiment, puts the concrete sleeper into the original wire pit, and directly uses the steel strand to connect with the above-mentioned conversion column as the wire.

Abstract

The invention discloses an urgent repair construction method for an anchor mast of a catenary. The urgent repair construction method includes installing an emergency steel column at the position of the broken anchor mast to position the catenary and avoid instability of the catenary due to large span; and using a transition mast adjacent to the broken anchor mast as a temporary anchor mast and adjusting the catenary to meet power transmission and traffic opening conditions. As the broken anchor mast is urgently repaired by existing equipment by the aid of the urgent repair construction method, influences of accidents on railway transport are reduced to the greatest extent.

Description

technical field [0001] The invention relates to a construction method for emergency repair of an anchor column, in particular to a construction method for emergency repair of an anchor column of a railway catenary. Background technique [0002] With the rapid development of my country's railways and the continuous increase of transportation tasks, the utilization rate of equipment continues to increase, and various faults continue to occur, one of which is the breaking of catenary anchor columns. The main reasons for this are firstly that the technology in the initial stage of construction is not particularly mature, and secondly that under normal circumstances the trains run in one direction, and the force on the catenary is also in one direction, causing the stressed anchor columns to break easily. The conventional method of repairing the anchor column in the prior art is to set up a new column next to the broken column, install a new guy wire, anchor the bearing wire to t...
