Embodiment Construction

[0014] The construction method of large-diameter steel pipes with self-made counterparts butt joints is realized by the following steps:

[0015] a. The production of the mouthpiece: first, select two arc-shaped stirrups 1 of the same size; then, weld N radial clamping plates 2 on the inner surface of each arc-shaped stirrup 1, and ensure that N The radial clamping plates 2 are arranged equidistantly along the circumferential direction; then, a connecting rod 3 is selected, and the two ends of the connecting rod 3 are respectively hinged with the first ends of two arc-shaped stirrups 1, and the two arc-shaped stirrups Rib 1, 2N radial clamping plates 2, and connecting rods 3 together form a hoop; then, select a T-shaped handle 4, and open a threaded concave hole on the longitudinal section end face of the T-shaped handle 4; then, select a T-shaped handle 4 root screw 5, and one end of the screw 5 is screwed into the threaded concave hole, and the other end of the screw 5 is hi...

Abstract

The invention relates to a large-diameter steel pipe butt joint construction technology in pipeline installation engineering, in particular to a large-diameter steel pipe self-made counterpart butt joint construction method. The invention solves the problems of high construction cost, low construction efficiency, high construction difficulty and poor construction safety in the traditional large-diameter steel pipe butt joint construction technology. The butt joint construction method of large-diameter steel pipes with self-made counterparts is realized by the following steps: a. Production of counterparts: first, select two arc-shaped stirrups with the same size; then, in each arc-shaped stirrup N radial clips are welded on the inner surface of each, and the N radial clips are arranged equidistantly along the circumference; then, a connecting rod is selected, and the two ends of the connecting rod are respectively connected with two arc-shaped hoops. The first ends of the ribs are hinged, and two arc-shaped stirrups, 2N radial clamps and connecting rods together form a hoop; b. Butt joint of large-diameter steel pipes. The invention is applicable to various pipeline installation projects.

Description

technical field [0001] The invention relates to a large-diameter steel pipe butt joint construction technology in pipeline installation engineering, in particular to a large-diameter steel pipe self-made counterpart butt joint construction method. Background technique [0002] The butt joint construction of large-diameter steel pipes is an important link in the pipeline installation project. The traditional large-diameter steel pipe butt joint construction technology is to use cranes, gantry, chain-down and other equipment to lift the large-diameter steel pipe, and then rely on manual pushing and crowbar assistance to realize the large-diameter steel pipe butt joint. Practice has shown that the traditional large-diameter steel pipe butt joint construction technology has the following problems due to its own limitations: First, in the butt joint process, the traditional technology needs to use a large number of workers and machines, and has high requirements for the coordinat...
