Abstract

The utility model relates to a precast cylindrical steel cylinder concrete pipeline corridor, which consists of a corridor body and a corridor way. The corridor way is cast in the corridor body, and the cross section of the corridor way is of a square shape, wherein (1).the corridor body is cylindrical, and two ends of the corridor body are respectively and coaxially fixed with a bell mouth and a spigot; and (2). the inside of the corridor body is coaxially embedded with a steel cylinder, and two ends of the steel cylinder are respectively and coaxially fixed on the bell mouth and the spigot. The precast cylindrical steel cylinder concrete pipeline corridor has the advantages of simple integral structure, scientific and reasonable design, convenient hoisting and transportation, lower cost of raw materials, simple construction process, and the capability of effectively resisting uniform settlement.

Description

Precast concrete pipe gallery with steel cylinder

Technical field

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

Background technique

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.Present piping lane is cast-in-site and forms, piping lane is a rectangular structure, be embedded with Framework Of Steel Reinforcement in the rectangular piping lane body wall, its making step of mainly constructing 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, process step is loaded down with trivial details, construction cost is higher, in the earthquake area that takes place frequently, be very easy to cause structural damage, also having a problem in addition is exactly that present piping lane impermeability is relatively poor, especially the higher place of level of ground water, be 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 purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, and design science is reasonable, lifting, convenient transportation, and the cost of raw material is lower, and construction process is simple, can effectively resist the precast concrete pipe gallery with steel cylinder of uneven settlement.

The utility model solves its technical problem and is achieved through the following technical solutions:

A kind of precast 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 is coaxial respectively birdsmouth and the interfaces of being fixed with in the two ends of the cylinder bodily form and corridor body;

(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.

And described gallery is coaxial in the corridor body.

And the outer wall of described interface is shaped on 1-3 seal grooves diametrically.

Advantage of the present utility model and beneficial effect are:

1. the corridor body of this piping lane is the prefabricated cylinder bodily 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. 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. be embedded with a steel cylinder in the tube wall of the corridor body of this piping lane, 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 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.

5. the utility model overall structure is simple, and design science is reasonable, lifting, convenient transportation, and the cost of raw material is lower, and construction process is simple, can effectively resist the precast concrete pipe gallery with steel cylinder of uneven settlement.
