Description

Wiring device of inverted U-shaped prestress braiding

Technical Field

The technology relates to the field of wiring devices, in particular to a wiring device for an inverted U-shaped prestress bundling.

Background

An inverted U-shaped prestressed steel bundle is arranged in an inner-layer containment vessel in the third-generation nuclear power technology 'Hualong I' independently researched and developed and designed in China, the number of the inverted U-shaped steel bundles is 94 in total, each bundle is composed of 55 steel strands with the nominal diameter of 1x7 of 15.7mm, the overall weight is about 10t, and the construction process is overall traction. The bundling process and the traction head treatment process are required to be carried out before the whole traction bundling process, the bundling process is required to be smooth in order to ensure that each process can be well connected in time and avoid the phenomenon of partial work types of waiting, and the progress meets the requirements of subsequent processes.

The bundling is to braid 55 steel strands into a complete steel bundle through a bundling pipeline surrounding the inner side of the gallery. Two problems are faced in construction: 1) because the number of the steel strands is large, the length of the steel strand is long (more than 200m), and the diameter of the pipeline is close to that of the steel strand, the initial single-pipeline binding steel strand is seriously clamped, the clamping is generally generated when more than 40 steel strands are penetrated, the continuity of subsequent processes is seriously restricted, and the clamped steel strand needs to be pulled out and scrapped after the clamping, so that more time is consumed, and materials are wasted. 2) According to the statistics of field construction experience, the time of the bundling process is 6-8 hours, the bundling process is generally 3-4 hours, and the next bundling process needs to be carried out after the steel bundle is pulled away from the wiring pipeline, which means that the bundling requirement cannot be met by bundling one by one, and the bundling need to wait for each other. Aiming at the problems, four wiring pipelines with two sizes are manufactured on site to solve the two problems, so that the smoothness of the weaving is guaranteed, and the time difference of each process of the weaving is well matched.

Disclosure of Invention

The invention aims to: the smooth and easy bundle of the prestress of the type of falling U of guarantee, avoid laying wire in-process frequent card pause to appear, promote to compile and restraint efficiency, let compile and restraint the link up that two processes can be fine in time.

The technical scheme of the invention is as follows: the wiring device comprises a wiring pipe, wherein the wiring pipe is positioned between an outer wall body and an inner wall body, and an inlet is formed in the outer wall body;

the wiring pipes comprise an auxiliary wiring pipe A, an auxiliary wiring pipe B, a main wiring pipe A and a main wiring pipe B, wherein the auxiliary wiring pipe A and the auxiliary wiring pipe B are bound with the main wiring pipe A and the main wiring pipe B, the main wiring pipe A and the main wiring pipe B are fixed on the bracket,

and steel beam walking rollers are arranged on the inner side wall body and comprise two rollers which are vertically arranged.

Wherein, the auxiliary wiring pipe A and the auxiliary wiring pipe B are bound with the main wiring pipe A and the main wiring pipe B through steel wires.

The main wiring pipe A and the main wiring pipe B are fixed on the bracket through buckles.

The number of the brackets is 48.

The support is uniformly fixed through a caliper gauge pre-buried in the concrete.

The inlets of the auxiliary wiring pipe A and the auxiliary wiring pipe B are at the same position.

The invention has the following remarkable effects:

1) and the blockage can not occur in the bundling process, so that the working efficiency is greatly improved, and the steel strand material is saved.

2) The two sets of wiring pipelines can ensure the continuous operation of the weaving and bundling and also ensure the continuous subsequent bundling process.

3) The method is favorable for specialized division of labor of the prestressed gallery operation, and the bunching and threading procedures are strictly separated and are well matched with each other in time.

4) Because the steel strand can not be clamped and repeatedly dragged, the quality of the steel strand damaged in the dragging process is avoided.

Detailed Description

An inverted U-shaped prestress binding wiring device, as shown in figure 1, comprises a wiring pipe 4, the wiring pipe 4 is positioned between an outer wall 2 and an inner wall 3, an inlet 1 is arranged on the outer wall 2,

as shown in fig. 1, the wiring duct 4 includes an auxiliary wiring duct a5, an auxiliary wiring duct B6, a main wiring duct a7, and a main wiring duct B8, wherein the auxiliary wiring duct a5 and the auxiliary wiring duct B6 are bound to the main wiring duct a7 and the main wiring duct B8 by steel wires, the main wiring duct a7 and the main wiring duct B8 are fixed on the bracket 10 by the buckle 9, and the total number of the brackets 10 is 48, and the brackets are uniformly fixed by a clamp embedded in concrete.
