Specific embodiment
The various embodiments that the present invention will be described in more detail that hereinafter reference will be made to the drawings.In various figures, identical element
It is indicated using same or similar appended drawing reference.For the sake of clarity, the various pieces in attached drawing are not necessarily to scale.
In the prior art, it because of the requirement of engineering construction, can often be applied in the position with underground utilities (pipeline 11)
Work, pipeline 11 can interfere the excavation of the earthwork, meanwhile, if the earthwork area of excavation is larger, pipeline can be made hanging, if will
Pipeline change moving, and more economy can be lost, also take time and effort.It is moved if not changing, because gravity can cause brokenly pipeline
It is bad.For the above phenomenon, the present invention provides a kind of construction methods reinforced for pipeline.
The embodiment of the present invention is described in detail below with reference to attached drawing 1 and attached drawing 2.
The present invention provides a kind of construction method reinforced for pipeline, the method is as follows:
The top mark of the earth excavation of corresponding position above pipeline to pipeline 11 is high (i.e. under 11 horizontality of pipeline most
The side of top), form operating pit；Overarm brace 12, and the overarm brace are set up on the operating pit overhead surface
12 both ends are respectively supported on the ground of the opposite sides of the operating pit；Fixed dress is set on the overarm brace 12
It sets, and through the fixed pipeline 11 of the fixed device；Continue the digging operation that predetermined depth is carried out to the earthwork.
Overarm brace 12 is set up above the pipeline 11；It is arranged between the overarm brace 12 and the pipeline 11 solid
Device is determined, for fixing the pipeline 11；The excavation of predetermined depth is carried out to the earthwork.
In the present embodiment, it is to the principle of the reinforcing of pipeline: in the fooled erection simple beam structure (overarm brace of the earthwork
12) lifting reinforcing, is carried out to pipeline by simply supported beam, prevents from damaging the pipeline after hanging.
In the present embodiment, while one kind is provided for pipeline bracing means, as shown in Figure 1, being pipe shown in Fig. 1
The implementation principle figure that line is reinforced.Pipeline bracing means includes overarm brace 12, and the erection method of the overarm brace 12 is:
On ground 15, the opposite sides of the earthwork piles up concrete foundation platform 1 respectively；In the concrete foundation
Built-in fitting 5 is set in platform 1, by the overarm brace 12 build on the concrete foundation platform 1 and with the built-in fitting 5
It is fixedly connected.
Concrete foundation platform 1 is built-up by concrete, has preferable stability, can have enough to the cross
The support force of boom support 12.Built-in fitting 5 provides the connection of overarm brace 12 and concrete foundation platform, makes overarm brace 12 more
It is firm.
In the present embodiment, the overarm brace 12 is made using angle steel, is fabricated to 800mm and is multiplied 1000mm size
Standard knot can use high strength exploitation between each standard knot, increase the length of the overarm brace 12, be opened with meeting
The larger overarm brace 12 of the earthwork of digging has enough length.
In the present embodiment, the overarm brace 12 includes: column 10, and each built-in fitting 5 is separately connected described in one
Column 10；Header board 4, two header boards 4 are arranged in parallel, and each 4 plate of the header board respectively with each column
10 connections；Truss 3, the truss 3 are fixedly connected between two header boards 4, the structural strength for web beam plate.
It is understood that the stability in order to ensure bonding strength and overarm brace 12, connects on each concrete foundation platform 1
At least two pillars 10 are connected to, make overarm brace 12 that there is better stability；Header board can be set it is multiple, for example, four
A header board can be combined into the box-like structure of cuboid, and three header boards can be combined into triangular prism structure, in box-like structure
Or be filled in triangular prism structure with truss 3,3 lightweight construction of truss, and be capable of the bonding strength of web beam bracket 12,
Make overarm brace 12 that there is better bending strength.
Preferably, it is connected between the column 10 and the built-in fitting 5 using welding manner, because in engineering construction,
The position of pipeline bracing means will not change again, ensure that the reliable of connection using welding between column 10 and built-in fitting 5
Property, loosening problem will not occur.It is understood that built-in fitting 5 can be welded to connect in advance with column 10, mixed
It, will be in the direct Transducers Embedded in Concrete basic platform 1 of built-in fitting 5 that be welded with column 10 when the building of solidifying earth foundation platform 1.Separately
Outside, it can be connected by screw bolts between column 10 and built-in fitting 5, be provided with threaded hole on built-in fitting 5, using bolt by column 10
It links together with built-in fitting 5, for example, being connected between column 10 and built-in fitting 5 using ring flange.
Institute in the present embodiment, state between header board 4 and the column 10 and the truss 3 and the header board 4 it
Between be all made of high-strength bolt 2 connection.The mode of being connected by screw bolts can assemble multiple header boards 4, and easy to disassemble.
In the present embodiment, it needs that pipeline is fixed, as shown in Figures 1 and 2, the fixed device includes:
The side on the header board close to the pipeline 11 is arranged in pulley 7, the pulley 7；It is arranged in crossbeam branch
The lower section of frame 12.
Guide chain 8, the guide chain 8 around the pulley 7 and 11 lower section of pipeline, hold up the pipeline for hanging respectively
11.Pipeline 11 is sling by guide chain 8, prevents pipeline 11 because bending damage vacantly occurs for lower section.Preferably, the pipeline 11
A neonychium 9 is arranged in the position that lower section is contacted with the guide chain 8, for avoiding the guide chain 8 from damaging the pipeline 11.
As it will be appreciated by those skilled in the art that, pipeline 11 has the position that connects of pipe, and guide chain 8 can be set
Pipe connects at position, can play better fixed effect.Neonychium 9 can use the rubber of U-shaped steel pipe and adequate thickness
Pad.Multiple guide chains 8 can be set, to meet the fixation to longer pipe line 11.In addition, fixed device may be arranged as a company
One end of extension bar and two " semicircular ring ", two " semicircular ring " are hinged and can be combined into an annulus, use two " semicircles
The hinged of ring " clamps pipeline 11, and then connecting rod and " semicircular ring " link together, i.e. realization consolidating to pipeline 11
It is fixed.
In the present embodiment, as shown in Fig. 2, it further includes cable wind rope 13 (cable wind rope 13 and crossbeam branch that pipeline, which reinforces rotary device,
Frame 12 can be connected with multiple angles, it is not limited to a kind of connection type, without display cable wind rope 13 and Fig. 2 in Fig. 1
Shown in be local cross-section diagram, there is no some other structures such as heatable adobe sleeping platform that display is excavated, as those skilled in the art
Member should understand that), the two sides perpendicular to its length direction on the overarm brace 12 are respectively equipped with cable wind rope 13, the cable
Wind rope 13 is fastened on the earth anchor 14 on ground 15.Enhance such as Fig. 2 middle cross beam bracket 12 or so two by setting cable wind rope 13
The stability of side.
As shown in Figure 1, building enclosure 6 is respectively set in the surrounding in the earthwork, for avoiding collapsing for the earthwork
And into the earthwork into soil.In engineering construction, the building enclosure of setting can protect facility and and construction in the earthwork
Personnel.
