The structure of pipe culvert tube coupling seam.
Background technology
To make, roadbed is continuous, current are unimpeded, it is necessary to build various sizes of drain structure thing, during small culvert is engineering structure
First-selection.Related data statistics shows：1～3 road of region of no relief/Km, 3～5 roads of mountain area/Km.In small culvert, culvert accounts for big absolutely again
Majority, in plains region, concrete circular pipe culvert accounts for more than 80%, have almost up to 100%, culvert is indispensable in highway.
Culvert belongs to upper portion pressurized, and by squeezing, end is exposed, the semi-underground engineering of middle flowing water for both sides.Most concrete circular pipe culverts make
There is different degrees of disease with rear, the form of expression is：Tube coupling crack (radially, longitudinally, crackle)；Tube coupling one end is overall heavy
Fall into；Colophonium loose hemp fiber between joints of segment comes off；Contain top roadbed settlement, jump car；Water is caused to connect from tube coupling by reasons such as crack, depressions
Mouth seepage, forms draining outside hole.
Pipe culvert disease Producing reason：1. the integraty of barrel part is poor, does not laterally have the knot being connected with each other between tube coupling
Structure, relies only on the lower bed course of section to keep, and when there is differential settlement, will result in tube coupling joint top or bottom and separates, mistake
Seam, water seepage from gap are gone out.2. the flat mouth between tube coupling docks form, though intermediate gap is clogged with Colophonium loose hemp fiber, its
Lateral shearing resistance still very little, when culvert pipe both sides subgrade soils are when filling and tamp uneven, in the presence of traffic load, contains and surveys
Subgrade soils necessarily side is first pressurized, opposite side is pressurized again, cause produce certain tube coupling lateral displacement, tube coupling interface position produce
Raw mismatch, water will be discharged from mismatch.3. not by design document and job specfication requirement, operate against regulations, such as barrel both sides are filled out
Soil is asymmetric, has unbalanced placement in layers and compacting, is open to traffic too early.Existing recovery technique is slow, complicated and effect is poor.
