specific Embodiment approach

[0029] A simple device for fast threading of super-long steel tie rods. It has multiple vertically arranged pedestals 1, which are assembled with angle steel and set at intervals of 1.5m. Each pedestal is leveled with a level;

[0030] Half of the pedestal 1 is used to install a semicircular auxiliary steel pipe 2, which is connected and fixed with the pedestal 1; the length of the auxiliary steel pipe 2 is consistent with the length of the steel tie rod, and its diameter is the same size as the outer steel pipe 3 of the steel tie rod; the auxiliary steel pipe 2 is used for wearing The placement of the steel tie rod in front of the pipe, after the steel tie rod is installed with the positioning ring, it is placed in the auxiliary steel pipe 2, so that it can be smoothly sent into the steel tie rod jacket steel pipe;

[0031] The other half of the pedestal 1 is used to place the steel tie rod jacket steel pipe 3 for wearing the pipe; and a hoop 4 is set to fix the steel tie rod ...

Abstract

The invention discloses a simple device for achieving rapid pipe penetrating of an overlength steel pull rod and an operation method of the simple device. The simple device is characterized in that a plurality of pedestals which are arranged longitudinally are arranged, half of the pedestals are used for mounting a semicircular assisting steel pipe, and the semicircular assisting steel pipe is connected with and fixed to the pedestals; the other half of the pedestals are used for containing a steel pull rod sleeve steel pipe for pipe penetrating; hoops are arranged to fix the steel pull rod sleeve steel pipe. The operation method includes the following steps that 1, the pedestals are arranged; 2, a steel rope is connected with a temporary nut; 3, a winding engine is pulled. The simple device has the advantages that steel pull rod pipe penetrating time is within 3-5 minutes, and pipe penetrating efficiency can be greatly improved; the penetrating size in the steel pull rod pipe penetrating process can be accurately controlled.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a simple device and an operation method for realizing fast passage of super-long steel tie rods into pipes. Background technique [0002] Nowadays, the anchorage system of long-span suspension bridges has gradually changed from the early section steel anchorage system or anchor cable anchorage system to the steel tie rod anchorage system. Therefore, steel tie rod piercing pipes will more and more commonly appear in bridge engineering. For the method of threading the steel tie rods, hoisting equipment is usually used to assist the steel tie rods to enter the outer steel pipes manually. This method takes 15-25 minutes, and the operation is not only complicated but also unsafe. However, using the hoist traction method to thread the pipe can shorten the time spent to 3-5 minutes, which greatly improves the efficiency of steel tie rod threading, especially for longer steel tie rods. ...
