Abstract

The utility model belongs to a measuring instrument, in particular relating to a reactor twolayer containment penetrating item sleeve coaxial degree adjusting rule. The adjusting rule consists of a vertical rule and a horizontal rule which are in cross orthogonality with the crossing point taken as a point of origin; the side face of the adjusting rule is marked with graduation lines which take millimeter as unit. Because the adjusting rule of the utility model consists of the vertical rule and the horizontal rule, the adjusting rule can be used to adjust both longitudinal dimension and horizontal dimension during measuring coaxial degree; therefore, the reactor twolayer containment penetrating item sleeve coaxial degree adjusting rule has the advantages of simple structure and convenient use.

Description

Reactor double containment penetration piece sleeve pipe right alignment is adjusted chi

Technical field

The utility model belongs to a kind of survey instrument, is specifically related to a kind of ruler that is used to adjust right alignment.

Background technology

Now some nuclear power plant reactor factory buildings adopt inside and outside two-layer two containment structures, stay space at regular intervals between the inside and outside containment, and are embedded with up to a hundredly to the penetration piece sleeve pipe on inside and outside containment body of wall, are used to install various technology penetration pieces.The technology penetration piece generally all is in manufacturer's processed finished product, and therefore the right alignment to pre-buried penetration piece sleeve pipe requires than higher.In practice of construction, require the inner containment wall construction prior to the shell body of wall usually, and before the outer containment construction, the penetration piece sleeve pipe on the inner containment that has has been put into the technology penetration piece in advance.Under these circumstances, guarantee the right alignment of inside and outside penetration piece sleeve pipe, existing technology has following two kinds:

1 by measuring the penetration piece sleeve pipe actual position coordinate of having buried underground on the inner containment body of wall, extrapolate the position coordinates of corresponding penetration piece sleeve pipe on the outer containment, control the burial place of this penetration piece sleeve pipe then with this coordinate, the right alignment of internal and external casing is met the demands.

The model of a technology penetration piece of 2 processing during penetration piece on burying outer containment underground, is set up this technology penetration piece model, adjusts the position of outer penetration piece sleeve pipe, and the right alignment of internal and external casing is met the demands.

Above-mentioned the 1st kind of prior art need be measured lot of data, and since containment stop and limitation of field condition that the coordinate precision that records is not high, cause final drive pipes concentricity to exceed tolerance deviation probably.In addition, measuring process needs the time long, also influences construction speed.Above-mentioned the 2nd kind of prior art when burying sleeve pipe underground on outer containment, all will be set up the penetration piece model and then adjust sleeve position, and it is very inconvenient to operate.In addition, when burying sleeve pipe underground on outer containment, put into the technology penetration piece on the penetration piece sleeve pipe of the inner containment that has, this method just can't be implemented.

Summary of the invention

The purpose of this utility model is to provide penetration piece sleeve pipe right alignment adjustment chi on a kind of reactor double containment simple in structure, easy to use.

Of the present utility modelly be achieved in that a kind of reactor double containment penetration piece sleeve pipe right alignment adjusts chi, adjust chi and form that joining is an initial point, indicates scale mark in its side by the linear foot and the crossfoot of the quadrature that is " ten " font.The scale mark of adjusting chi is unit with the millimeter.

In the utility model, adjust chi and form, when measuring right alignment, both can be used to adjust longitudinal size, can adjust lateral dimension again, therefore the utility model has the advantages that: simple in structure, easy to use by the linear foot and the crossfoot of the quadrature that is " ten " font.

Description of drawings

Fig. 1 adjusts the chi structural drawing for a kind of reactor double containment penetration piece sleeve pipe right alignment that provides of the present utility model;

Fig. 2 utilizes the utility model to adjust the principle schematic of right alignment;

Among the figure: 1 adjusts chi, 2 backguys.

Embodiment

As shown in Figure 1, a kind of reactor double containment penetration piece sleeve pipe right alignment is adjusted chi, adjusts chi and is made up of the linear foot and the crossfoot of the quadrature that is " ten " font, and joining is an initial point, indicates scale mark in its side.The scale mark of adjusting chi is unit with the millimeter.

As described in Figure 2, penetration piece sleeve A B is the penetration piece sleeve pipe on the inner containment tube wall of having constructed, CD be will construction and installation on the outer containment the penetration piece sleeve pipe, now require two penetration pieces coaxial.The position of adjusting penetration piece cannula C D makes it coaxial with the penetration piece sleeve A B on the inner containment of finishing of constructing, implements as follows:

(1) elder generation is with the design attitude that is placed on of CD penetration piece sleeve pipe;

(2) adjusting the center that chi is found out two sleeve pipes by the A end of penetration piece sleeve A B, the D end of penetration piece cannula C D with two, and by the center backguy;

(3) measure lateral dimension and the vertical dimension of backguy to penetration piece sleeve pipe B end and C end tube wall; Adjust the D end position of penetration piece cannula C D, make backguy to the horizontal direction at penetration piece B end center and vertical deviation in the coaxiality deviation scope of allowing.

(4) keep the D end of penetration piece cannula C D motionless, adjust the C end position, make backguy to the horizontal direction at C end center and vertical deviation in the coaxiality deviation scope of allowing.

(5) said process repeatedly meets the demands up to right alignment, then fixing penetration piece cannula C D.

By the position of the definite outer containment penetration piece sleeve pipe of above-mentioned steps adjustment, the most approaching with the design attitude of itself under the situation that satisfies the right alignment requirement, therefore be optimum position.

Claims

1. a reactor double containment penetration piece sleeve pipe right alignment is adjusted chi, and it is characterized in that: described adjustment chi is made up of the linear foot and the crossfoot of the quadrature that is " ten " font, is initial point with the joining, indicates scale mark in its side.

2. a reactor double containment penetration piece sleeve pipe right alignment is adjusted chi, and it is characterized in that: the scale mark of described adjustment chi (1) is unit with the millimeter.
