Technical field

The invention belongs to civil construction technical fields, and in particular to a kind of Pipe installing depth of parallelism inspection method.

Background technique

The heap chamber ringwall of reactor building is equipped with eight groups of thrust kerves, and every group of thrust kerve is inside and outside arranged not by two Casing with caliber is welded to form, and casing is welded by two kinds of tubing again, requires high, concentricity to its concentricity and the depth of parallelism And the depth of parallelism requires to be within deviation 1mm, every group of thrust kerve upper and lower level has a root canal road, eight groups of thrust kerves totally 16 root canal Road, is divided to two kinds of specifications, and pipe range is 1320mm and 1488mm.Currently, generally in order to guarantee concentricity and the depth of parallelism, first in workshop Prefabricated installation after passed examination, adds support and fixes, huge structure, installation before binding prior to reinforcing bar, reinforcing bar binding need to pass through plus Fixing structure body, labor efficiency is low, while being easy to touch reinforcing body, influences the quality for detecting work.

Summary of the invention

The present invention aiming at the shortcomings in the prior art, provides a kind of Pipe installing depth of parallelism inspection method, is a kind of installation The depth of parallelism inspection method of complicated stereoeffect state inside and outside the intracorporal pipeline of wall, overcoming existing need to shift to an earlier date Prefabricated reinforced, structural body is huge, reinforcing bar binding trouble, is easy the deficiencies of touching, checks that flexible, measurement is convenient.

To achieve the above object, the invention adopts the following technical scheme: a kind of Pipe installing depth of parallelism inspection method, including Following steps:

S1 makes Pipe installing casing, and casing inner diameter is identical as the small pipe outside diameter of pipeline to be installed；

S2 makes two circular pipes and checks mold, and first checks the diameter of mold and the small pipe outside diameter phase of pipeline to be installed Together, second check that the diameter of mold is identical as the big bore of pipeline to be installed；Mark out two inspection mold center's point positions；

Total station is arranged in S3, makes instrument and checkpoint intervisibility, and instrument actual coordinate and elevation is arranged in backsight known point；

Measurement on the inside of S4 casing: securing the cannula at support frame, checks that mold is embedded in casing, measuring center point for first Coordinate；

The deviation of casing: azimuth deviation value Δ α=(- (X-X is calculated in S5₀)×SINα+(Y-Y₀)×COSα)× 1000；

The big pipe position of rear repetition measurement pipeline is welded and fixed in S12, whether deviation is within 1mm for absolute altitude, if meeting, continues S13；

S13 repeats step S9 to S12 to the pipeline of the second layer, and the big pipe of the pipeline of the second layer is mounted on the second of support frame Layer, the position for making the big pipe of the pipeline of the second layer, absolute altitude deviation are within 1mm, while two layers of pipeline of satisfaction is parallel and two layers is managed The horizontal direction parallel degree deviation in road is within 1mm；The pipeline pipe welding of the second layer is fixed on installation support frame.

To optimize above-mentioned technical proposal, the concrete measure taken further include:

Pipeline to be installed is integrally formed along its length by the different tubule of diameter and big pipe, and the diameter of tubule is less than big The diameter of pipe, small pipe outside diameter are identical as big bore.

First checks that mold checks that the diameter of mold is identical with second.

Support frame has upper layer and lower layer, and two pipelines are individually fixed in the upper and lower of support frame.

In step S7, if repetition measurement sleeve position, absolute altitude deviation are not less than 1mm, S6 is carried out.

The length of casing is 10mm, and casing length too long cannot rotate in order to avoid influencing pipeline.

First checks that mold and second checks that the thickness of mold is 3mm.

It is equipped with leader on first inspection mold and the second inspection mold, is used for hand-held.

The beneficial effects of the present invention are: the present invention not only can be detected accurately according to the actual situation, to obtain more Accurate detection as a result, on heap chamber ringwall thrust kerve installation when physical location adjustment provide reliable basis, and And easy tool subsidiary is used, and it is easy to operate, it checks on the quality reliable, measurement is convenient, flexible, without in advance in vehicle Between it is prefabricated, and reinforced, while solving that the pipeline depth of parallelism checks difficult up and down, effectively meet the matter to site operation Amount requires, and compared with original parallelism detection method, substantially increases detection efficiency.
