Technical Field

The invention belongs to the technical field of building bolt embedding methods, and particularly relates to a deviation control method for an embedded sleeve of a compressor foundation bolt.

Background

The product compression unit compressor is the largest steam-driven compressor in the industry, the original loading inlet of Mitsubishi Japan, the weight is 800 tons, the compressor enters the field in a 3-section modularization mode, the basic structure form and the external dimension of the product compressor are raft type frames 10.75m (width) 33m (length) 20.3m (height) 1.85/2.45 (thickness of a top plate of the compressor), the engineering quantity of the basic frames is about 310 tons of reinforcing steel bars, templates are about 4020 square, and concrete is about 2130 cubic meter, as the concrete with thicker thickness of the top plate of the compressor foundation is poured by adopting the integral inclined plane layering method, the concrete is easy to extrude the sleeve after entering the mould, so as to cause displacement, the traditional method is to weld the sleeve and the steel bar of the top plate, but the method has poor effect, because the displacement of reinforcing bar is aroused because roof reinforcing bar arranges more difficult avoiding vibrator can touch the reinforcing bar at the concrete vibration in-process, directly leads to the sleeve pipe position to produce the skew after the reinforcing bar takes place the displacement. In order to solve the problem, the deviation control method of the compressor foundation bolt embedded sleeve is invented, the position accuracy of the embedded sleeve is improved, and the construction effect is good.

Disclosure of Invention

The invention aims to solve the problems and provide a deviation control method of a compressor foundation bolt embedded sleeve, which has a simple structure and reasonable design.

The invention realizes the purpose through the following technical scheme:

a deviation control method for an embedded sleeve of a base bolt of a compressor comprises the following steps:

step 1: laying a bottom template of the foundation top plate, and arranging an axis control line on the surface of the bottom template;

step 2: positioning the embedded bolt sleeve through an axis control line, and marking a positioning point;

and step 3: fixing an elastic positioning piece at the positioning point;

and 4, step 4: fixing the embedded bolt sleeve and the elastic positioning piece;

and 5: and (4) checking the embedded bolt sleeve by using the upward movement of the axis control line.

As a further optimization scheme of the invention, step 6: and (5) moving downwards by using an axis control line to recheck the bottom position of the embedded bolt sleeve.

As a further optimization scheme of the invention, step 3: the elastic positioning piece is a wood wedge, and the wood wedge is anchored with the bottom template.

As a further optimization scheme of the invention, step 4: the embedded bolt sleeve is sleeved on the wood wedge and is bound with the steel bar for fixing.

As a further optimization scheme of the invention, step 7: after the embedded bolt pipe sleeve is checked, the top is integrally tied and fixed by adopting a steel pipe or integrally welded and tied steel bars.

The invention has the beneficial effects that: the problem that can effectual solution tradition buried bolt sleeve pipe takes place the displacement easily, utilizes the straightness that hangs down that bolt buried pipe is controlled to the control axis of moving about freely and quickly that the level set up for buried bolt sleeve pipe influences greatly reduced by the displacement when concrete placement in advance, has improved buried sleeve pipe's position accuracy, and the construction effect is better, suitable popularization and application, and this method still is applicable to equipment foundations such as compressor, steam turbine, coal pulverizer, and the application is wide, uses comparatively in a flexible way.
