Description
Technical Field
The technology relates to the field of wiring devices, in particular to a wiring device of an inverted U-shaped prestress braiding beam.
Background
The three-generation nuclear power technology 'Hualong No. I' of independent research and development design in China is provided with inverted U-shaped prestress steel bundles in an inner containment, the inverted U-shaped steel bundles are 94 in total, each bundle consists of 55 steel strands with 1x7 nominal diameter of 15.7mm, the whole weight is about 10t, and the construction technology is whole traction. The beam braiding process and the traction head treatment process are needed before the whole traction beam threading, so that the time connection of the processes can be well ensured, the phenomenon that part of work types lean against each other is avoided, the beam braiding process can be ensured to be smooth, and the progress meets the requirements of the subsequent processes.
The bundling is to bundle 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 strands is longer (more than 200 m), and the diameter of the pipeline is close to that of the steel strands, the original single-pipeline bunching steel strands are seriously clamped, and generally more than 40 steel strands are penetrated, clamping can occur, the continuity of the subsequent process is seriously restricted, and the clamped steel strands are required to be pulled out and scrapped after clamping, so that more time is required to be consumed, and materials are wasted. 2) According to the statistics of site construction experience, the beam-forming process needs 6-8 hours, the beam-forming process is generally 3-4 hours, and the next beam-forming process needs to be performed after the steel beam is pulled away from the wiring pipeline, which means that the beam-forming cannot meet the beam-forming requirement, and the beam-forming and beam-forming need to wait each other. In order to solve the problems, two large wiring pipelines, two small wiring pipelines and four wiring pipelines are manufactured on site, so that smooth beam braiding is ensured, and the time difference of each beam penetrating process is well matched.
Disclosure of Invention
The invention aims at: the inverted U-shaped prestress beam braiding is guaranteed to be smooth, clamping is avoided frequently in the wiring process, beam braiding efficiency is improved, and two procedures of beam braiding and beam penetrating can be well connected in time.
The technical scheme of the invention is as follows: the wiring device of the inverted U-shaped prestress braided beam 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 tube comprises an auxiliary wiring tube A, an auxiliary wiring tube B, a main wiring tube A and a main wiring tube B, wherein the auxiliary wiring tube A and the auxiliary wiring tube B are bound with the main wiring tube A and the main wiring tube B, the main wiring tube A and the main wiring tube B are fixed on a bracket,
And steel bundle walking rollers are arranged on the inner wall body and comprise two rollers which are vertically arranged.
Wherein the auxiliary wiring tube A and the auxiliary wiring tube B are bound with the main wiring tube A and the main wiring tube B through steel wires.
The main wiring tube A and the main wiring tube B are fixed on the bracket through buckles.
The total number of the brackets is 48.
The bracket is uniformly fixed by a clamping gauge pre-embedded in the concrete.
The inlets of the auxiliary wiring pipe A and the auxiliary wiring pipe B are positioned at the same position.
The invention has the remarkable effects that:
1) The binding process can not be blocked, so that the work efficiency is greatly improved, and the steel strand materials are saved.
2) The two sets of wiring pipelines can ensure continuous operation of bundling, and simultaneously ensure continuous bundle penetrating procedures.
3) The method is favorable for specialized division of prestress gallery operation, and the beam braiding and beam penetrating procedures are strictly separated and well matched with each other in time.
4) Because the clamping and repeated dragging of the steel strand cannot occur, the quality of the steel strand is prevented from being damaged in the dragging process.
