Abstract
The utility model relates to the technical field of highway facilities, in particular to a reinforcing steel bar concrete circular pipe culvert which is formed by splicing of multiple circular pipe bodies. The end face of the splicing end of two adjacent circular pipe bodies is a mutually-matched winding face, the end face of the splicing end is transformed to the mutually-matched winding face from a plane of the prior art, two winding faces are mutually matched to increase a contacting area and form a certain occlusion dynamics, and therefore, soundness of a splicing position is improved. Therefore, the reinforcing steel bar concrete circular pipe culvert is not only solid, but also simple in structure, suitable for various geology conditions and especially suitable for being used in a saturated yielding loess area.
Description
Technical field
The utility model relates to the highway facilities technical field, is specifically related to a kind of Collapsible Loess District steel reinforced concrete pipe culvert that is applicable to.
Background technology
The present domestic pipe culvert that mostly adopts is 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 connects.In the construction of speedway and the certain hour scope built up, the sedimentation of roadbed is inevitable, be subjected to simultaneously the effect of carload, the differential settlement of roadbed also exists, and because of the difference of stressed position and stressed size, existing pipe culvert is easy to the crack, the band of smearing of joint performs practically no function, therefore settlement joint place tube coupling unreasonable structure very easily causes the infiltration of pipe culvert in addition, finally causes the sedimentation of roadbed.
As shown in Figure 1, China's patent ZL200620078450.3 has designed a kind of pipe culvert that is applicable to Collapsible Loess District for this reason, comprise a plurality of circular bodys 1, its special character is: also comprise ring-shaped rubber waterstop 3 and clip 2, described rubber fastening band 3 is arranged at the end of adjacent body 1, clip 2 is installed with the outside of ring-type rubber fastening band 3 on adjacent body 1, and it is enhanced pipe culvert percolation-proof, the ability of leaking.But in the situation of the differential settlement of roadbed, its stitching position is still firm not, the problem of crack and then infiltration often occurs.
The utility model content
In order to address the above problem, the purpose of this utility model is to provide a kind of steel reinforced concrete pipe culvert, with the fastness of further raising stitching position.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of steel reinforced concrete pipe culvert is stitched together by a plurality of circular bodys; Wherein, the end face of the splice ends of two adjacent round tube bodies is the zig zag plane that cooperatively interacts.
Further, the end face seal of the splice ends of described two adjacent round tube bodies docking.
Further, the end face of the splice ends of described two adjacent round tube bodies is smeared fluid sealant.
Further, also be provided with the ring-shaped rubber waterstop in the end of the splice ends of described two adjacent round tube bodies, also be set with clip in the described ring-shaped rubber waterstop outside.
Further, leave the slit between the splice ends of described two adjacent round tube bodies, be provided with the pitch loose hemp fiber in this slit.
Compared with prior art, the utility model has changed the end face of its splice ends into cooperatively interact zig zag plane by the plane of prior art, two zig zag planes cooperatively interact and have increased contact area, and form certain interlock dynamics, and then have improved the fastness of stitching position.
Therefore, the utility model is not only more firm, and simple in structure, is not only applicable to various geological conditionss, is particularly useful for Collapsible Loess District and uses.

The specific embodiment
Describe the utility model in detail below in conjunction with accompanying drawing and specific implementation method, be used for explaining the utility model in schematic enforcement of the present utility model and explanation, but not as to restriction of the present utility model.
Embodiment 1:
As shown in Figure 2, a kind of steel reinforced concrete pipe culvert is stitched together by a plurality of circular bodys 1, and wherein the end face of the splice ends of two adjacent round tube bodies 1 is the zig zag plane that cooperatively interacts.The zig zag plane structure that specifically cooperatively interacts is shown in Fig. 3-5:
As shown in Figure 3, this two end face that cooperatively interacts is " Z " font;
As shown in Figure 4, this two end face that cooperatively interacts is " triangle " and " V-type groove ";
As shown in Figure 5, this two end face that cooperatively interacts presents " zigzag " of mutual interlock.
Need to prove that the end face that two in the utility model cooperatively interacts is not limited to above-mentioned three kinds of shapes, can also for other regular and irregulars can mutually be connected amalgamation together, have other zig zag planes of certain snap-in force.
As shown in Figure 2, in order further to improve the fastness of stitching position, be provided with ring-shaped rubber waterstop 3 in the end of the splice ends of two adjacent round tube bodies 1, also be set with clip 2 in ring-shaped rubber waterstop 3 outsides; Between the splice ends of two adjacent round tube bodies 1, leave the slit, be provided with pitch loose hemp fiber 4 in this slit.
For percolation-proof, the end face seal of the splice ends of two adjacent round tube bodies 1 docking, and also the end face of the splice ends of two adjacent round tube bodies 1 is smeared fluid sealant.
More than technical scheme that the utility model embodiment is provided be described in detail, used specific case herein principle and the embodiment of the utility model embodiment are set forth, the explanation of above embodiment is only applicable to help to understand the principle of the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, all will change on the specific embodiment and range of application, in sum, this description should not be construed as restriction of the present utility model.
