Embodiment Construction

[0012] Describe the present invention in detail below in conjunction with embodiment:

[0013] A method for positioning the lower injection branch pipe of a coke oven, including measuring with a variable-distance square ruler with an X-axis ruler and a Y-axis ruler, which adopts the following steps:

[0014] (1) While burying the fixed threaded casing, install pre-embedded steel plates on one side of its two ends to fix the two ends; use theodolite and steel tape to measure and determine the centerline of the spiral casing;

[0015] (2) In the threaded casing, use theodolite and steel tape to measure and determine the auxiliary installation center line of the coke oven lower spray branch pipe;

[0016] (3) Place the coke oven lower injection branch pipe in the threaded casing, and determine the center position of the coke oven lower injection branch pipe by measuring with a variable distance square on the center line of the auxiliary installation;

[0017] (4) Weld the first ...

Abstract

The invention relates to a locating method of pipeline, in particular to a locating method of the downward spray branch pipe of a coke oven. The steps are that: arrange an embedded steel plate on one side of the two end surfaces of a spiral sleeve when the spiral sleeve is embedded and fixed; determine the central line of the spiral sleeve by measurement; measure the auxiliary installation central line of the downward spray branch pipe by using a theodolite or a steel tape; determine the central location of the coke oven downward spray branch pipe by measuring with a variable range square through the auxiliary installation central line; weld a first angle steel at the excircle surface of the upper end of the coke oven downward spray branch pipe and at the same level with the upper end surface, weld a second angle steel with the first angle steel into a whole at the same horizontal plane, and then adjust the direction of the variable range square after the upper end surface of the coke oven downward spray branch pipe is fixed, a horizontal ruler is placed along the X-axial direction of the variable range square; finally weld and fix the bottom end surface of the coke oven downward spray branch pipe after the vertical degree of the horizontal ruler is tested by using the variable range square. The invention can improve the embedding accuracy of the coke oven downward spray branch pipe and has the advantages of improving work efficiency and reducing the crossed construction of different work.

Description

Technical field: [0001] The invention relates to a pipeline positioning method, in particular to a positioning method for a coke oven lower spray branch pipe. Background technique: [0002] Domestic coke oven lower injection pipes are divided into direct-buried and pre-buried threaded casings. The construction process is to use steel structure fixing frames for positioning, and the whole process of measurement is tracked. There are many construction procedures and cross-type work, resulting in many factors affecting the positioning accuracy. Invention content: [0003] The purpose of the present invention is to overcome the disadvantage of low positioning accuracy in the construction process of the background technology and provide a positioning method for the coke oven lower nozzle branch pipe that can improve the positioning accuracy. [0004] Realize above-mentioned invention and adopt following technical scheme: [0005] A method for positioning the lower injection br...
