Abstract
The invention relates to a precast prestressed concrete pipe gallery with a chamfer angle, consisting of a gallery body and a gallery passage. The gallery passage is arranged in the gallery body, and the cross section of the gallery passage is square, wherein (1) the gallery body is cylindrical, and two ends of the gallery body are coaxially and fixedly provided with a bearing port and a plugging port respectively; (2) the outer pipe wall of the gallery body is fixedly provided with a protecting layer, and prestressed wires are winded on the outer pipe wall of the gallery body in the protecting layer; and (3) the cross section of the gallery passage is square, and any one of four angles is the chamfer angle. The invention has simple integral structure, scientific and reasonable design, convenient lifting and transportation, simple construction process and lower cost of raw materials and construction, and is capable of effectively resisting uneven settlement.
Description
Technical field
The invention belongs to the piping lane field, especially a kind of precast prestressed concrete pipe gallery with chamfering.
Background technique
Present piping lane is cast-in-site and forms, and piping lane is a rectangular structure, is embedded with Framework Of Steel Reinforcement in the rectangular piping lane body wall, owing to will bear bigger external pressure load, the corridor body wall of piping lane is thicker.The main effect of piping lane is and gas pipeline, feedwater piping, drainage pipe, intermediate water pipeline, heat supply pipeline and telecommunication cable etc. can be converged; Its advantage is: once excavate, concentrate construction, avoided same highway section to repeat excavation.The main construction making step of piping lane comprises: fluting, supporting, precipitation, reinforcing bar binding, formwork, cast concrete, maintenance, form removal, backfill.The subject matter that existing piping lane exists is: the piping lane molding time is long, and process step is loaded down with trivial details, and construction cost is higher, in the earthquake area that takes place frequently, be very easy to cause structural damage, and the piping lane overall weight is bigger, as precast units, very inconvenience of lifting, transportation and construction.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of precast prestressed concrete pipe gallery with chamfering is provided, this piping lane overall structure is simple, design science is reasonable, lifting, convenient transportation, and construction sequence is simple, raw material and construction cost are lower, can effectively resist uneven settlement.
The present invention solves its technical problem and is achieved through the following technical solutions:
A kind of precast prestressed concrete pipe gallery with chamfering is made of corridor body, gallery, and gallery is in the corridor body, and the cross section of gallery is a square, wherein
(1). the corridor body be the cylinder bodily form and at the two ends of corridor body coaxial respectively birdsmouth and the interface of being fixed with;
(2). the tube wall outer wall of corridor body is fixed with a protective layer, is wound with reinforcement wire on the outer wall of this protective layer middle corridor body;
(3). any angle that the cross section square of gallery is four jiaos is a chamfering.
And described gallery is coaxial in the corridor body.
And the outer wall of described interface is shaped on 1-3 seal groove diametrically.
And described protective layer is cement mortar protective course or concrete cover.
Advantage of the present invention and beneficial effect are:
1. the corridor body of this piping lane is the precast units form, and its two ends are provided with birdsmouth and interface, and directly install the job site behind fluting, has avoided cast-in-site, has shortened the time of site operation, has improved efficiency of construction, has reduced the cost of construction.
2. the corridor body of this piping lane is the cylinder bodily form, can make things convenient for the lifting and the transportation of this precast concrete pipe gallery, and in the construction and installation process, has reduced the frictional force with ground, improves efficiency of construction.
3. the cylinder bodily form corridor body tube wall outer wall of this piping lane is fixed with protective layer; and below this protective layer, be wound with reinforcement wire on the tube wall outer wall of corridor body; increase piping lane integral body and resisted the ability of external pressure load; and can reduce the thickness of corridor body wall; reduce the weight of whole piping lane, convenient lifting, transportation and construction.
4. any angle of four jiaos of the cross section squares of this piping lane gallery is a chamfering, helps the expansion of gallery inner space, makes reasonably allocation space of the various pipelines that accumulate in the gallery and cable.
5. the corridor body of this piping lane is formed by the Steel Fiber Reinforced Concrete cast, has saved Framework Of Steel Reinforcement, in today that the iron and steel price goes up day by day, has reduced the cost of raw material, has improved economic benefit.
6. the outer wall of the interface of this piping lane directly upwards is shaped on 1-3 seal groove, O-ring seal can be installed, make whole piping lane have good joint water closure, and this interface is a flexible interface, interface can rotate to an angle with respect to birdsmouth, help resisting the uneven settlement on basis, reduce the structural damage of piping lane.
7. overall structure of the present invention is simple, and design science is reasonable, lifting, convenient transportation, and construction sequence is simple, and raw material and construction cost are lower, are a kind of precast prestressed concrete pipe galleries that can effectively resist the band chamfering of uneven settlement.
Description of drawings

Embodiment
The invention will be further described below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
A kind of precast prestressed concrete pipe gallery with chamfering, constitute by corridor body 3, gallery 5, gallery is coaxial in the corridor body, the corridor body is formed by the Steel Fiber Reinforced Concrete cast, the cross section of gallery is a square, this square can be that positive square also can be the square type, and the cross section of present embodiment gallery shown in the drawings is positive square, and innovative point of the present invention is:
(1). the corridor body is coaxial respectively birdsmouth 7 and the interfaces 1 of being fixed with in the two ends of the cylinder bodily form and corridor body, birdsmouth and interface are respectively the annulus of steel, the outer wall of this interface is shaped on 1-3 seal groove 2 diametrically, and the interface outer wall directly upwards is shaped on 2 seal grooves in the present embodiment accompanying drawing;
(2). the tube wall outer wall at cylinder bodily form corridor body is fixed with a cement mortar protective course 6, is wound with reinforcement wire 4 on the tube wall outer wall of this protective layer middle corridor body, and above-mentioned cement mortar protective course also can be a concrete cover.
(3). any angle that the cross section square of gallery is four jiaos is a chamfering 8, and this chamfering can be rounding, and present embodiment gallery cross section shown in the drawings square is rounding for four jiaos.
The precast prestressed concrete pipe gallery of this band chamfering when mounted, O-ring seal is installed in 2 seal grooves of the outer wall of interface, seal by O-ring seal between interface and the birdsmouth, when running into foundation settlement or earthquake, birdsmouth can rotate a certain angle with respect to interface, to resist uneven sedimentation.
