Description
Technical field
The invention belongs to municipal works technical fields, are related to a kind of device enhancing buried pipeline rigidity and anti-torsion.
Background technology
City planting ductwork is the important infrastructure in a city, including:Power conduits, storm sewer, sewage conduct, water supply
Pipeline, fire protection pipeline, gas pipeline, communication conduit etc., wherein most piping laying is in underground.In operation in use, buried
Pipeline is influenced and the effect of upper load due to being rolled by natural subsidence and vehicular traffic so that the soil body bears larger
Pressure is easily sunk, and differential settlement is formed.It may be influenced simultaneously by proximity constructing tunnel, to native around pipeline
Body generates disturbance deformation, and pipeline can also be affected, and shift deformation and torsion etc., seriously affects pipeline normal operation, and
Booster phenomenon may occur, jeopardize people's production and living.
Invention content
The object of the present invention is to provide a kind of device that can enhance buried pipeline rigidity and anti-torsion, the device of the invention
In pipeline along spiral to arrangement reinforcing bar, when buried pipeline, screwdriver is turned by loaded member, tensile stress is applied to reinforcing bar, made
Reinforcing bar tenses, and certain rigidity is provided for pipeline.Technical solution is as follows：
The device of a kind of enhancing buried pipeline rigidity and anti-torsion, including loaded member and at least a reinforcing bar, feature exist
In every reinforcing bar in buried pipeline outer periphery spiral to arrangement, fixed by the first fixing end and second respectively by the both ends of reinforcing bar
End is connected with buried pipeline, offers threaded hole in the junction of buried pipeline, the first fixing end and the second fixing end are all provided with
It is equipped with the fixing piece for fixed steel bars end and the insertion bolt that is connected with fixing piece, is inserted into the size of bolt and threaded hole
Match, two fixing pieces to be fixed on buried pipeline；One of fixing piece is rod failure fixing piece；The load
Part includes fixing piece with holes and the screwdriver for tensing reinforcing bar, the bar being arranged on rod failure fixing piece and the hole of fixing piece with holes
Size and position are corresponding.
Preferably, the reinforcing bar is at least two, along identical spiral to being arranged in buried pipeline periphery or described
Reinforcing bar be at least two, along different spirals to being arranged in buried pipeline periphery.
The operation principle of the present invention is that：It has the following advantages：
1, during pipeline runs use, due to the effect of various factors, the offset of different directions can occur for pipeline, when
When pipe sedimentation difference or offset deformation reach certain numerical value, reinforcing bar tensile stress increases, and device starts to play a role, for improving pipe
Differential settlement is resisted in road, and resists the ability of all directions deformation.
2, during pipeline runs use, due to the effect of various factors, it can twist between pipeline, work as torsion angle
When degree reaches certain numerical value, reinforcing bar tensile stress increases, and device starts to play a role, and improves the ability that pipeline resists torsion.

Specific implementation mode
The present invention is described in detail with reference to the accompanying drawings and examples.
Embodiment 1
As shown in Figure 1, the present invention is a kind of device enhancing buried pipeline rigidity and anti-torsion ability, including reinforcing bar 1, the
One fixing end 2, the second fixing end 3 and loaded member 4.
It is equipped with threaded hole close to socket in pipeline outer wall, screws on and is inserted into bolt 23, bolt 23 is inserted into and is equipped with six
Angle nut 22 and fixing piece 21 are used for fixed steel bars 1, the screw thread on one end of screwed reinforcing bar 1 and fixing piece 21 are twisted
It is good.
When buried pipeline, pipeline along the hand of spiral to arrangement reinforcing bar 1.By the screw thread and rod failure of 1 other end of reinforcing bar
The screw thread of fixing piece 31 and fixing piece with holes 42 is twisted.The application drawing of reinforcing bar 1 is answered by turning the screwdriver 41 in loaded member 4
Power makes reinforcing bar 1 tense.
According to Practical Project, can the pipe rings of several water supply lines one reinforcing bar is set.Circumferentially at least it is arranged symmetrically 2 spiral shells
Rotation reinforcing bar can circumferentially be arranged symmetrically 3-4 root reinforcing bars for the big region of deforming displacement.
During pipeline runs use, due to the effect of various factors, differential settlement and non-Tongfang can occur for pipeline
To offset deformation, when pipeline offset deformation reach certain numerical value when, reinforcing steel bar bear is tightened up, and device starts to play a role, energy
It enough improves pipeline and resists differential settlement, and resist the ability of all directions deformation, to reduce offset deflection.
During conduit running, due to the effect of various factors, pipeline can twist, when pipeline windup-degree reaches
When certain numerical value, reinforcing steel bar bear is tightened up, and device starts to play a role, and can improve the ability that pipeline resists torsion, reduces pipe
Road torsional capacity.
As shown in Fig. 2, the first fixing end 2 includes fixing piece 21, hex nut 22 and insertion bolt 23.Fixing piece 21 is fixed
It on hex nut 22, is threaded thereon, for connecting one end of reinforcing bar 1.It is inserted into bolt 23 to be threaded, pipe can be screwed into
Road.
As shown in figure 3, the second fixing end 3 includes rod failure fixing piece 31, hex nut 22 is inserted into bolt 23 and loaded member 4.
There are 4 fixed links 311 on rod failure fixing piece 31, be used for fixed belt hole fixing piece 42, be threaded thereon, is used for fixed steel bars 1.
Loaded member 4 includes screwdriver 41 and fixing piece with holes 42.Fixed link 311 is inserted on fixing piece 42 with holes, fixing piece 42 with holes
It is threaded, is used for fixed steel bars 1.It is connected with screwdriver 41 on fixing piece 42 with holes.Reinforcing bar is tightened by bit rotary screwdriver 41
1, apply tensile stress for reinforcing bar 1, reinforcing bar is made to be in tight state before being taken into use, to shift deformation and torsion in pipeline
When turning, tensile stress is generated, enhances pipeline rigidity and anti-torsion ability.
