Background

At present, in hoisting construction for installing large pipelines, a movable crane is generally adopted for hoisting, the crane is flexible to move and strong in universality, operation and construction are far more convenient than methods of erecting a gantry crane and the like, and the use cost is relatively low.

The connection structure of the reinforced concrete pipes is shown in fig. 1, and comprises two adjacent reinforced concrete pipes 1 and a rubber ring 2 positioned between the adjacent reinforced concrete pipes 1. One end of the reinforced concrete pipe 1 is provided with a socket 11 integrally formed with the reinforced concrete pipe, and the inner diameter of the socket 11 is larger than the outer diameter of the reinforced concrete pipe 1, so that a step is formed between the socket 11 and the reinforced concrete pipe 1. The one end that reinforced concrete pipe 1 kept away from bell and spigot 11 is the insertion end of reinforced concrete pipe 1, and rubber ring 2 is located bell and spigot 11 inside and laminates mutually with the step surface that forms between bell and spigot 11 and the reinforced concrete pipe 1, and through the butt joint between the adjacent reinforced concrete pipe 1, adjacent reinforced concrete pipe 1 carries out extrusion deformation to rubber ring 2 to the junction between adjacent reinforced concrete pipe 1 seals, avoids it to appear leaking.

In the traditional pipeline butt joint method, firstly, a crane slowly lifts a pipeline to an excavated trench, then constructors slowly push the pipeline to the position above a butt joint position on two sides of the pipeline, finally, the crane slowly puts a jacking pipe to the position opposite to the pipeline, and finally, an excavator pushes the pipeline to enable the pipeline to be connected with the installed pipeline in an inserted mode. If the position is not aligned at one time, the crane still needs to be hoisted again, and the construction steps are repeated, so that the construction difficulty is high.

The sling is lifted around the pipe and adopts a special high-strength nylon sling to avoid damaging the concrete of the pipe body. Before hoisting, the gravity center of the pipe body is found out and marked.

Step three, tube descending and tube stabilizing:

Pipe laying: when the pipe is lowered, the bell and spigot of the reinforced concrete pipe 1 faces the flowing water direction.

Tube stabilization: after the pipeline is in place, two groups of four wedge-shaped concrete cushion blocks are properly added on two sides of the reinforced concrete pipe 1 to prevent the pipe from rolling. When the reinforced concrete pipe 1 is installed, the center and the elevation of the water flowing surface of the pipeline are adjusted section by section, so that the elevation of the longitudinal section and the plane position of the reinforced concrete pipe 1 are accurate. After each pipe section is in place, the pipe sections are fixed to prevent the reinforced concrete pipe 1 from displacing. During pipe stabilization, the pipe is firstly put into the pipe for inspection and butt joint, so that the phenomenon of staggered joints is reduced. The elevation deviation of the inner bottom of the tube is within +/-l 0mm, the center deviation is not more than l0mm, and the stagger of the inner bottoms of the adjacent tubes is not more than 3 mm.
