Specific embodiment
It elaborates below with reference to example embodiment to technical solutions of the utility model.However, example embodiment
It can implement in a variety of forms, and be not understood as limited to embodiment set forth herein；On the contrary, provide these embodiments
So that the utility model is more comprehensively and completely, and the design of example embodiment is comprehensively communicated to those skilled in the art
Member.
As shown in Figure 1, it is the structure diagram of resistance absorber in the present invention；As shown in Fig. 2, it is resistance absorber in Fig. 1 of the present invention
Side view；As shown in figure 3, it is the vertical view of resistance absorber in Fig. 1 of the present invention.
The structure of resistance absorber includes：Including：Upper arc panel 1, arc lower plate 2, insulating rubber slab 3, connection bolt 4, stud
Plate 5.
Upper arc panel 1 is respectively arranged with engaging lug 6 on two sides, and the shape of upper arc panel 1 is semicircular arc.
Arc lower plate 2 is respectively arranged with engaging lug 6 on two sides, and the shape of arc lower plate 2 is semicircular arc；Three pieces
Vertical rib plate 5 is connected on the outer wall of arc lower plate 2, and vertical rib plate 5 is parallel with the axis of arc lower plate 2.The outer edge of arc lower plate 2
For arc, other shapes can also be used.Upper arc panel 1, arc lower plate 2 material use steel plate of the thickness for 12mm.Stud
The material of plate 5 is the steel plate that thickness is 16mm, is highly 100mm.
Engaging lug 6 is provided with connection through-hole, and connection bolt 4 is mounted in connection through-hole.Upper arc panel 1, arc lower plate 2 pass through
The shape after bolt 4 combines is connected as cylinder.Insulating rubber slab 3 sets upper arc panel 1 after combining, arc lower plate 2
Inside.The material of insulating rubber slab 3 is the electro-insulating rubber pad of thickness 5mm.
Using the construction method of resistance absorber, following steps are specifically included：
Step 1：Resistance absorber is mounted on to the position that close end is leaned on pipeline；
Arc lower plate 2 is placed in the lower part of pipeline, and vertical rib plate 5 is made to be supported on suit inner wall, insulating rubber slab 3 is padded
Between pipeline and arc lower plate 2, and wrap on the outside of pipeline.The width of insulating rubber slab 3 is required than 2 width of arc lower plate simultaneously
Big 100mm, in order to avoid pipeline anticorrosion coating is caused to be damaged by lower curved plate stress.
Highway section pipeline Crossing by Pipe Pushing Construction, jacking bore DN1200, outer diameter D N1400, concrete reinforced pipe is as defeated
Feed channel casing, engineering jacking crossing length be 100m, 152.6 meters of overall length.Rising to high speed gutter 3.5m for pipeline, it is supreme
Fast road surface 4.0m, until natural ground 11.5m.
Pipeline specifications：D508 × 8.0mm, using longitudinal submerged arc welded pipe, material is L415 grades, and wherein bend pipe is using warm
It simmers, bending radius 6D.Design pressure 6.3MPa, pumped (conveying) medium are two class natural gas.
The welding technique of pipeline is using semi-automatic down hill welding technology by hand.Pipeline Crossing Program concrete set of tubes length is 104m, is examined
Steel conduit is considered during concrete casing is worn, and as pipeline weld length is continuously increased, makes pipeline dead weight and and casing
Contact surface increases, and causes frictional resistance increase during Pipeline Crossing Program.In order to reduce the resistance during Pipeline Crossing Program, push pipe is applied
Resistance absorber is employed in work.
Step 2：Upper arc panel 1 is placed on insulating rubber slab 3, the connection through-hole of engaging lug 6 is to just, connecting bolt 4
It is sleeved on and is added gasket in connection through-hole and is fastened using nut；
Step 3：By the telescopic rod of push-bench withstand on pipeline end (install protection facility additional between telescopic rod and pipeline,
In order to avoid causing pipeline during jacking, the end face of pipeline is damaged, influences pipe joint welding quality), it is pushed away to pipeline application
Power, pipeline move under thrust into casing, and vertical rib plate 5 is slided on suit inner wall, and resistance absorber moves together with pipeline
It is dynamic；
Due to the supporting role of resistance absorber, the contact surface between vertical rib plate 5 and casing is small, so as to reduce pipeline and casing
The frictional force of inner wall reduces the frictional resistance between pipeline and casing, accelerates the speed of application of Pipeline Crossing Program.
Step 4：After the pipeline sleeve pipe of half length, stop applying thrust to pipeline, be installed at the middle part of pipeline
Resistance absorber continues to press on pipeline to set in-pipe, until pipeline is completely into casing after installation is complete.
During if necessary to connect next pipeline, pipeline is continued to press on after the completion of pipeline welding to in-pipe is covered, directly
Casing is passed through to pipeline completion.If pipeline is longer, multiple resistance absorbers can be installed on pipeline, resistance absorber is in the length of pipeline
Direction is evenly arranged.
By using resistance absorber, the duration of a project can shorten the construction period, so as to save construction cost.
Term used in the utility model is explanation and term exemplary, and not restrictive.Due to the utility model energy
The enough spirit or essence being embodied in a variety of forms without departing from utility model, it should therefore be appreciated that above-described embodiment is unlimited
In any aforementioned details, and should widely be explained in the spirit and scope that appended claims are limited, therefore fall into power
Whole variations and remodeling in profit requirement or its equivalent scope all should be appended claims and covered.
