Embodiment 1

[0042] see figure 1 , the load-bearing mechanism used for the underground pipeline pressure device provided by the present invention includes a jack 4, and also includes a back wall 1 and a diameter adjustment mechanism 2. The back wall 1 is a detachable steel structure, and one end of the jack 4 passes through the diameter adjustment mechanism. 2 is tightened against the back wall 1, and the other end of the jack 4 is tightened with the pipeline to be pressed through the tooling;

[0043] see figure 1 as well as figure 2 , in this embodiment, the back wall 1 is made of a plurality of I-shaped steels criss-crossed to form a grid structure, so the back wall 1 has multiple supporting points, and the installation and manufacturing process is simple, which will not affect the construction period. The disassembly is convenient; at the same time, the back wall 1 can be reused, and can be recycled and environmentally friendly after being used many times.

[0044] see figure 1, i...

Embodiment 2

[0049] Further, in order to ensure that the pipeline can be inserted into the soil at a certain inclined angle during construction. see figure 1 , the carrying mechanism for the underground pipeline pressure device provided in embodiment 1 also includes an angle adjustment mechanism 3, one end of the angle adjustment mechanism 3 is fixed on the diameter adjustment mechanism 2, and the other end of the angle adjustment mechanism 3 is locked with one end of the jack 4 , used to adjust the tilting angle of the jack 4.

[0050] see Figure 5 as well as Figure 6 , in this embodiment, the angle adjustment mechanism 3 includes a fixed seat 31, a movable seat 32, a limit ring 34, a clamping member 33, and a spherical valve; the fixed seat 31 and the movable seat 32 are connected through a spherical valve, and the limit The ring 34 is arranged on the fixed seat 31, and the spherical valve is limited by the limit ring 34, and the clamping part is fixed on the movable seat 32, and is...

Embodiment 3

[0058] Embodiment 1 provides the construction method of bearing mechanism, including:

[0059] 1) Adjust the opening range of the diameter adjustment mechanism 2, so that the reaction force of the jack 4 to the tooling acts on the annular force surface on the back wall 1 to match the contact surface of the jack 4;

[0060] 2) One end of the jack 4 is tightened with the back wall 1 through the diameter adjustment mechanism 2, and the other end of the jack 4 is tightened with the pipeline to be pressed through the tooling;

[0061] 3) The back wall 1 of the jack 4 acts as a reaction force and presses against the annular stress surface of the tooling, and pushes the pipeline into the soil through the tooling.

[0062] Specifically, in this embodiment, the diameter adjustment method in step 1) is to adjust the horizontal opening range between the left fixed plate 221 and the right fixed plate 222 through the telescopic rod 25, and at the same time, according to the diameter of the...

Abstract

The invention belongs to the technical field of pipeline construction, and relates to a bearing mechanism and construction method for an underground pipeline jacking device. The bearing mechanism comprises a jack and is characterized in that the bearing mechanism further comprises a rear back wall and a diameter adjusting mechanism; the rear back wall is of a detachable steel structure, one end ofthe jack is tightly propped against the rear back wall through the diameter adjusting mechanism, and the other end of the jack is tightly propped against a pipeline to be jacked through a tool; and the bearing mechanism further comprises an angle adjusting mechanism, one end of the angle adjusting mechanism is fixed on the diameter adjusting mechanism, and the other end of the angle adjusting mechanism is locked with the jack. The bearing mechanism provided by the invention has the advantages that the construction time is not affected, and the bearing mechanism can be repeatedly used, and isrecyclable, environmentally friendly, stable in stress, and safe and reliable; and meanwhile, the bearing mechanism can also adjust the inclination angle of the jack, the angle requirement of pipelineconstruction is met, the operation is simple, and the construction efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of pipeline construction, and relates to a bearing mechanism and a construction method for an underground pipeline top pressure device. Background technique [0002] During the construction of underground pipelines, if the construction environment is open, you can directly excavate a certain depth at the bottom line and bury the pipelines underground; however, during the construction of most underground pipelines, there are many obstacles such as houses, buildings and mountains on the ground. At this time, an area will be selected, a foundation pit with a depth of 5 to 6 meters will be excavated, the pipeline will be put into the pit, the pipeline will be driven into the soil by the top pressure of the pipeline through the tooling, and the soil falling inside the pipeline will be taken out to realize The construction of underground pipelines; however, because the diameter of the pipeline is 1.8 to 2.5 meters...
