The precast prestressed longitudinal bar concrete pipeline corridor has the advantages of simple integral structure, scientific and reasonable design, convenient hoisting and transportation, simple construction steps, and lower cost of raw materials and construction; and the precast prestressed longitudinal bar concrete pipeline corridor is capable of effectively resisting uniform settlement.

Description

Precast prestressed concrete pipe gallery with longitudinal bar

Technical field

The utility model belongs to the piping lane field, especially a kind of precast prestressed concrete pipe gallery with longitudinal bar.

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 purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of precast prestressed concrete pipe gallery with longitudinal bar is provided, and 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 utility model solves its technical problem and is achieved through the following technical solutions:

A kind of precast prestressed concrete pipe gallery with longitudinal bar 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 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;

(3). 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 grooves diametrically.

And described protective layer is cement mortar protective course or concrete cover.

Advantage of the present utility model 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 uniform N root that is embedded with in the tube wall of corridor body is indulged muscle, and the span of N is 1≤N≤50, and the two ends of this vertical muscle are packed in respectively on birdsmouth and the interface, have increased the ability of integrally-built stability of piping lane and opposing external pressure load.

4. 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.

5. the outer wall of the interface of this piping lane is shaped on 1-3 seal grooves 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.

6. the utility model overall structure 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 gallery with longitudinal bar that can effectively resist uneven settlement.
