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.Also having a problem in addition is exactly that present piping lane impermeability is relatively poor, and especially the higher place of level of ground water is easy to cause the short circuit of cable corrosion and low-voltage distribution equipment at the inner wet environment that forms of piping lane.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of precast prestressed reinforced concrete pipe gallery with steel cylinder 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 reinforced concrete pipe gallery with steel cylinder 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 coaxial steel cylinder that is embedded with in the tube wall of corridor body, the two ends of this steel cylinder are coaxial respectively to be packed on birdsmouth and the interface;
(3). the coaxial uniform vertical muscle of N root that is embedded with in the tube wall of corridor body, the span of N is 1≤N≤50, the two ends of this vertical muscle are packed in respectively on birdsmouth and the interface;
(4). the tube wall outer wall of corridor body is fixed with a protective layer, is wound with reinforcement wire on the tube wall outer wall of this protective layer middle corridor body.
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, the uniform inboard that is arranged on steel cylinder of vertical muscle in the described corridor body tube wall, the perhaps outside.
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 piping lane, and in the construction and installation process, has reduced the frictional force with ground, improves efficiency of construction.
3. this piping lane coaxial steel cylinder that is embedded with in the tube wall of corridor body, the two ends of this steel cylinder are coaxial respectively to be packed on birdsmouth and the interface, and steel cylinder, birdsmouth and interface connect into an integral body, and the impervious of whole piping lane obviously improved.
4. the coaxial uniform vertical muscle of N root that is fixed with in the corridor body tube wall of this piping lane, the span of N is 1≤N≤50, the two ends of this vertical muscle are packed in respectively on birdsmouth and the interface, have increased the ability that piping lane integral body is resisted the external pressure load.
5. 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 tube wall; reduce the weight of whole piping lane, convenient lifting, transportation and construction.
6. the outer wall of the interface of this piping lane is shaped on 1-3 seal groove diametrically, 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 reinforced concrete pipe gallery with steel cylinder that can effectively resist uneven settlement.
