Description
Technical field
The utility model belongs to the bellows that the construction of culvert is related to, more particularly to a kind of burst for culvert shaping is spelled
Dress formula corrugated steel pipe.
Background technology
The construction of traditional Buried culvert under roadbed shaping, typically using rigid precast concrete pipeline is pre-buried or cast-in-place concrete
Construction molding is carried out, is not suitable for the quick formation of the Buried culvert under roadbed and general subgrade culvert of arc line shaped；In construction for
Roadbed high roadbed unfavorable geology section of foundation, it is difficult using based process during corresponding Concrete Arch Culvert, construction quality be difficult to ensure card and
It is costly.Secondly, mountain area natural waterway is complicated, and need to use needs large volume to excavate massif during straight culvert pipe, and curve steel can be set
Corrugated culvert is disposed.Because the raw material such as the related rubble of the regional casting concrete had inconvenient traffic, sand lack, construction is used
Water is difficult or the material haul distance such as cement, steel farther out, the culvert construction that besides emergency repair, disaster relief etc. need to be rapidly completed.
Human resources extremely lack or high altitude anoxia area, are influenceed by the duration or construction seasons weather restricts, difficult using concrete structure
Meet quality and construction period；It is unfavorable for the construction of Buried culvert under roadbed formation under complex geological condition, this is mainly Buried culvert under roadbed
The construction technology and method of shaping need to improve.A kind of brand-new corrugated steel pipe how is used to be used for the construction for being molded culvert, with
Shorten culvert shaping duration, it is ensured that the quick formation of the Buried culvert under roadbed under different geological conditions, realize in road construction into
Shape culvert technological progress, reaches complete road structure technical quality effect, and formula needs to solve the problems, such as in the prior art.
The content of the invention
The utility model is for above shortcomings, the utility model provide a kind of burst pin-connected panel in the prior art
Corrugated steel pipe is molded the construction technology of culvert, the construction skill of easily designed and construction burst assembling type steel corrugated pipe forming culvert
Art improved method.
The technical solution of the utility model：A kind of burst assembling type steel bellows for culvert shaping, it is characterised in that：
Connected and composed by some corrugated steel pipe bursts, the corrugated steel pipe assembly discrete piece is split according to corrugated steel pipe circumference expansion direction
In flakes, every is all identical radian, and bolt hole is correspondingly arranged in every corrugated steel pipe assembly discrete piece surrounding；If by dry plate steel
Bellows assembly discrete piece carries out being assemblied to form circle, is penetrated corresponding to the two panels corrugated steel pipe assembly discrete piece in connection in bolt hole
Bolt, and flat shim and convex pad are set, tightening nut, docking forms circular corrugated steel pipe tube coupling.
Further feature is：Between the two panels corrugated steel pipe assembly discrete piece of connection, flat shim and convex pad are set,
Between bolt head and corrugated steel pipe assembly discrete piece, flat shim is set, between nut and corrugated steel pipe assembly discrete piece, set convex
Pad, tightening nut will each corresponding corrugated steel pipe assembly discrete piece connection.
Between adjacent corrugated steel pipe tube coupling and tube coupling, section seam vertically is cross-linked.
Between corrugated steel pipe tube coupling and tube coupling, and the corresponding bolt hole by being set on adjacent corrugated steel pipe tube coupling
Inside penetrate bolt, nut and connect.
The flat shim is that circular, middle hole is used for through bolt, and its upper and lower side is all plane.
The convex pad is that circular, middle hole is used for through bolt, and one in its upper and lower side is raised.
The utility model is used for the burst assembling type steel bellows of culvert shaping, relative to prior art, has following special
Point：
（1）Working procedure can be simplified：Culvert location is carried out by design requirement and digs base, when substrate soil is the bad soil such as mud
During layer, it should change and fill out processing.It should avoid backbreaking.Such as backbreak, loose part should be purged to processing.Dig to the soil property base of absolute altitude
Must not cheat and expose for a long time, disturb or soak, and foundation ditch size should be checked in time, elevation, base bearing capacity, should after meeting the requirements
Immediately carry out containing base construction operation.
（2）Buried culvert under roadbed can quickly be formed：After culvert base excavates to be formed, gravel basis is laid, is then covered with the dry mixing of bottom
After concrete, carry out corrugated steel pipe and connect to form integrated piping, corrugated steel pipe is attached installation admittedly by the length dimension of determination
After fixed, mesh sheet of mating formation on corrugated steel pipe circumference reinforcing bar, cushion block protective layer is stayed to carry out banding fixed.Fill dry-mix concrete, after
Foundation ditch groove is tamped, backfill culvert area's earthwork forms path formation face after rolling.
（3）The Buried culvert under roadbed technology formed using burst assembling type steel bellows, the phase of corrugated steel pipe protective layer can be achieved
It should improve：When corrugated steel pipe have galvanizing surface reach durability, two be filling dry-mix concrete can form long-term nature
Culvert constructs；The design of roadbed complex geological condition is applied to, the invasion that can be overcome and improve geology natural waterway has reached
Whole road structure mass effect；To ensure that the culvert structure after the solidification of the dry-mix concrete of filling is complete, outside corrugated steel pipe
Layer with the addition of the design of mesh sheet reinforcing bar, because corrugated steel pipe has certain length flexible to radian, for the complicated geological of roadbed
Condition, it can also realize the formation installation of curve culvert, it is ensured that the quick formation of road construction.
In a word：, can using the construction technology and construction method of the burst assembling type steel corrugated pipe forming culvert after improvement
Shorten the duration, it is ensured that the roadbed under different geological conditions is quickly formed, and realizes the technical quality effect of Buried culvert under roadbed complete structure
Fruit, the construction technical schemes of road construction project also can be synchronously included, improve existing road construction job specfication.
