Description
Technical field
The invention belongs to steel reinforced concrete pipe culvert recovery technique fields, and in particular to one kind is used for RC Circular
The inner bearing type connection structure of pipe culverts reparation.
Background technology
Pressure on circular reinforced concrete culvert is the culvert pattern generally used in highway, railway and municipal works.With culvert
The increase of service life, under the influence of the factors such as load action and ground inhomogeneous deformation, some steel reinforced concrete pipe culverts
Tube coupling at there is tube coupling and the diseases such as disengage, grind one's teeth.Through investigation, in some junior geologic zones, tube coupling joint is maximum to be disengaged
Distance alreadys exceed 200mm.Tube coupling disengages and grinds one's teeth etc. diseases as repaired not in time, then culvert leakage and erosion can be caused to break
It is bad, the normal use of culvert is influenced, flood period can also result in Highway；And soil particle is lost in around culvert, in roadbed
It is interior to form cavity, directly influence the bearing capacity of roadbed and the performance on road surface.
In engineering, the technology requirement to pressure on circular reinforced concrete culvert tube coupling connector (or deformation joint) antiseep is to work as phase
When relative deformation occurs for adjacent tube coupling (or deformation joint side pieces), impervious material or leakage preventing structure can adapt to and comply with this change
Shape, and keep barrier performance.
In culvert reparation, using pitch loose hemp fiber or the filling of other flexible materials disengages and seepage place, can solve
The culvert leakage problems that tube coupling gap at joint width is smaller, tube coupling relative deformation is smaller or deformation has tended towards stability.For phase
The relative deformation of adjacent tube coupling is still within the culvert pipe hole in sustainable development stage, if the impervious material clogged can not adapt to compared with
Big deformation (for example, under cryogenic), with the increase of tube coupling relative deformation, impervious material can gradually take off glutinous or come off,
Antiseepage disabler.Tube coupling joint if (or deformation joint) has disengaged larger distance, completely using choke material antiseepage
There is also economy problems.
Have achievement in research, patent and current art standard pin to put forward newly-built steel reinforced concrete pipe culvert design and construction
A series of seepage control measure of culvert pipe joints is gone out.For example, the Chinese invention patent of Application No. 200610041827.2, application number
For 200620078450.3 Chinese invention patents and the Chinese invention of Application No. 200820147205.2.But for reinforcing bar
Concrete circular pipe culvert tube coupling connector leaks damage repair or method of disposal, current rare report.Newly-built pressure on circular reinforced concrete culvert
Mainly implement anti-seep measure on the outside of culvert pipe before roadbed filling in hole.These methods are difficult to apply to inside culvert pipe.If
Subgrade and pavement is excavated, repairs waterproof construction again, traffic operation can be affected greatly.Due to pressure on circular reinforced concrete culvert
Hole inner space is narrow and small (most of a diameter of 1.5m and below 1.5m of culvert), using the reparation side of slab culvert and box culvert deformation joint
Method, construction operation difficulty are larger.It being needed using slip casting restorative procedure using pore-forming equipment, only the techniques such as slurry are relatively complicated for closure,
Cost is also higher.
