Abstract
The utility model relates to the technical field of road construction, and discloses a reinforced concrete round pipe culvert. The reinforced concrete round pipe culvert comprises a round pipe body (1) and annular connectors (2), annular lugs (5) are arranged on the end portion of the round pipe body (1), annular grooves (6) are formed in the end faces of the annular connectors (2), the annular lugs (5) are matched with the annular grooves (6), contact areas are enlarged, matched end faces can be meshed with each other, and splicing is firm. Connecting seams (7) are formed between the annular lugs (5) and the annular grooves (6), the connecting seams are filled with seaming materials (3), sealing glue (4) coats the surfaces of the connecting seams (7), and effect sealing can be carried out to prevent water seepage. The splicing faces of the annular lugs (5) and the annular grooves (6) are frosted surfaces, friction of contact surfaces is enlarged, and combination tightness is further enhanced. The reinforced concrete round pipe culvert is compact in structure, convenient to mount, firm in splicing and capable of well solving the water seepage problem of the reinforced concrete round pipe culvert.
Description
Technical field
The utility model relates to the road construction technical field, relates in particular to steel reinforced concrete pipe culvert.
Background technology
The current domestic steel reinforced concrete pipe culvert mostly adopted, be formed by connecting by the tube coupling of a plurality of circular bodys.Jointing all adopts cement mortar to smear band, and the tube coupling at settlement joint place adopts the joint filling of pitch loose hemp fiber, twines the rope made of hemp outward, outermost parcel pitch burlap is connected.In the construction of speedway and a period of time scope of building up, the sedimentation of roadbed is inevitable, be subject to the effect of automobile load simultaneously, the differential settlement of roadbed also exists, difference because of stressed position and stressed size, existing pipe culvert is easy to infiltration, finally causes the sedimentation of roadbed.
Existing pipe culvert comprises a plurality of circular bodys, ring dress rubber fastening band and clip, rubber fastening band is arranged at the end of adjacent body, clip is installed with in the outside of adjacent body pressed on ring dress rubber fastening band, improve the percolation-proof of pipe culvert, the ability of preventing water leakage, but in the situation that settlement of subgrade, its stitching position is insecure, still can not solve the problem of crack infiltration fully.
Summary of the invention
The utility model is insecure for pipe culvert splicing in prior art, can not solve the shortcoming of infiltration fully, provides splicing firmly, the steel reinforced concrete pipe culvert of the fine solution seepage problem of energy.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals.
Steel reinforced concrete pipe culvert, comprise circular body and ring joint, and the round tube end of body is provided with annular lug, and the ring joint end face is provided with annular groove, and annular lug matches with annular groove.Annular lug and annular groove splicing coordinate, enlarge active surface, reduce seam, easy construction, in addition, annular lug and ring joint splicing coordinate, form certain interlock dynamics, make steel reinforced concrete pipe culvert have certain rigidity, splicing firmly, intensity is large, can be applicable to preferably various geological conditionss.
As preferably, the internal diameter of circular body with the internal diameter of ring joint than being 1:(0.85～1.0).The ring joint internal diameter is less than or equal to circular body, in conjunction with closely, splices firmly, can effectively reduce the harm such as infiltration.
As preferably, annular lug length and annular groove depth ratio are 1:(1.0～1.2).The annular groove degree of depth is more than or equal to the length of annular lug, and annular lug can extend in annular groove fully, makes accurate positioning between circular body and ring joint, connects closely, is conducive to disperse upper load, connects more stable.
As preferably, annular lug thickness with the annular groove width than being 1:(1.0～1.5).It is wide that annular lug thickness is less than or equal to annular groove, and annular lug can easily be spliced in annular groove, accurate positioning, easy construction.
As preferably, annular lug external surface and annular groove inner surface are the plucking surface.The plucking surface can effectively increase the contact surface friction, disperses contact surface shear stress, splice more firmly, effectively reduces culvert splicing place that subgrade settlement causes and seeps water.
As preferably, be provided with connecting sewing between annular lug external surface and annular groove, be filled with joint filler in connecting sewing, fluid sealant is smeared on the splicing seams surface.The setting of joint filler, filled the space between the splicing end face, improved the water proofing property between steel reinforced concrete pipe culvert; The setting of fluid sealant, can effectively permeate the gap of filling between the splicing end face, further improved the water proofing property between steel reinforced concrete pipe culvert.
The utility model is owing to having adopted above technical scheme, steel reinforced concrete pipe culvert, comprise circular body and ring joint, the round tube end of body is provided with annular lug, the ring joint end face is provided with annular groove, and annular lug matches with annular groove, has strengthened contact area, form certain interlock dynamics, improved the fastness of stitching position; Projection external surface and annular groove inner surface are the plucking surface, increase the contact surface friction, splice more firm; Be provided with connecting sewing between annular lug external surface and annular groove, be filled with joint filler in connecting sewing, fluid sealant is smeared on the splicing seams surface, has filled the space between the splicing end face, water-tight.The utility model, compact conformation, easy for installation, splicing is firm, the problem of the fine solution steel reinforced concrete pipe culvert infiltration of energy.
