Description

Steel cylinder strengthened steel faucet concrete ceiling coil

Technical field

The utility model relates to concrete plug, especially a kind of steel cylinder strengthened steel faucet concrete ceiling coil.

Background technique

Push pipe generally is applied in geographical environment and does not allow the operation of slotting, and construction environment requires noise less, traffic is not exerted an influence, and does not cause under the situation of surface subsidence, for example: the underground construction of railroad crossing, highway private wire.Concrete ceiling coil as waste pipe is generally non pressure pipe at present, concrete ceiling coil causes breakage because of the influence of factors such as it is rectified a deviation to the concrete of the concrete ceiling coil mouth of pipe easily in the process of construction, thereby influence the sealability of joint, and when pressure line carries out jacking construction, direct jacking pressure tubing, concrete ceiling coil that need caliber is enough big carries out jacking earlier as sleeve pipe, setting pressure pipeline in sleeve pipe then, therefore strengthened the construction comprehensive cost of concrete ceiling coil, and the Watertightness of available coagulation soil push pipe pipeline is also undesirable.

Present concrete ceiling coil is because carrying external pressure load and internal water pressure are limited, so be mainly used in drainage pipe.Available coagulation soil push pipe runs into foundation settlement when carrying sewage sometimes, causes the body fine fisssure, the phenomenon of effluent seepage occurs, severe contamination around water body environment, person health is caused bad influence.

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, withstand voltage, corrosion-resistant, impermeability and joint water closure good, and comprehensive cost is low, the steel cylinder strengthened steel faucet concrete ceiling coil of convenient construction.

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

A kind of steel cylinder strengthened steel faucet concrete ceiling coil, constitute by bellmouth, socket, cylinder type Framework Of Steel Reinforcement and concrete tube core, wherein bellmouth and the coaxial respectively two ends that are packed in the concrete tube core of socket, the cylinder type Framework Of Steel Reinforcement is coaxial to be packed on the bellmouth and socket of concrete pipe in-core, it is characterized in that: the coaxial steel cylinder that installs respectively on the bellmouth of concrete pipe in-core and socket.

And described cylinder type Framework Of Steel Reinforcement is to install the cylinder type Framework Of Steel Reinforcement pipe cage that forms by two coaxial cylinder type reinforcement cages are coaxial by bearing rod, perhaps is the cylinder type reinforcement cage of individual layer.

And described cylinder type reinforcement cage is installed by circumferential reinforcement and longitudinal steel bar and forms.

And, the coaxial bellmouth of concrete pipe in-core and the outer rim or the inner edge of socket of being packed in of described cylinder type Framework Of Steel Reinforcement.

Advantage of the present utility model and beneficial effect are:

1. the concrete tube core of this concrete ceiling coil adopts the one-piece casting moulding, and dispose steel cylinder at the concrete pipe in-core, so improved the impermeability of whole body greatly, and made tubing have very strong resistance to pressure, improved external pressure load and the interior ability of pressing resisted.

2. this concrete ceiling coil adopts flexible faucet structure, and socket can be installed sealing rubber ring in its groove in installation process, and this just makes this tubing have good joint water closure, and the opposing uneven settlement is very capable.

3. this concrete ceiling coil adopts the bellmouth and the socket of steel, has reduced bellmouth and socket end face concrete sustains damage because of being subjected to shearing force, has strengthened the sealability of whole pipeline.

4. the steel cylinder of this concrete ceiling coil is inlaid in the concrete pipe in-core, by the alkaline environment that concrete provides, has effectively protected steel cylinder, has improved the antiseptic property of tubing, has prolonged the tubing life-span.

5. the utility model overall structure is very simple, and design science is reasonable, has favorable durability, impermeability, joint water closure, and engineering cost is low, greatly reduce construction cost, is the higher steel cylinder strengthened steel faucet concrete ceiling coil of a kind of novelty.

Embodiment

The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.

A kind of steel cylinder strengthened steel faucet concrete ceiling coil, constitute by bellmouth 7, socket 1, cylinder type Framework Of Steel Reinforcement and concrete tube core 3, wherein bellmouth and the coaxial respectively two ends that are packed in the concrete tube core of socket, bellmouth and socket are steel, adopt the O-ring seal sealing during installation.The cylinder type Framework Of Steel Reinforcement is coaxial to be packed on the bellmouth and socket of concrete pipe in-core, this cylinder type Framework Of Steel Reinforcement is by two coaxial cylinder type Framework Of Steel Reinforcement pipe cages that form that install by bearing rod 5 of coaxial cylinder type reinforcement cage, each cylinder type reinforcement cage is to be installed by circumferential reinforcement 4 and longitudinal steel bar 6 to form, the inboard cylinder type reinforcement cage of this cylinder type Framework Of Steel Reinforcement pipe cage is packed on the outer rim of the bellmouth of concrete pipe in-core and socket (being generally Type of Welding), also the outside cylinder type reinforcement cage of cylinder type Framework Of Steel Reinforcement pipe cage can be packed on the inner edge of the bellmouth of concrete pipe in-core and socket, the present embodiment accompanying drawing is that inboard cylinder type reinforcement cage is packed on the outer rim of the bellmouth of concrete pipe in-core and socket.The coaxial steel cylinder 2 that installs respectively on the bellmouth of concrete pipe in-core and socket inner edge.

Joint socket of the present utility model is a flexible interface, socket can be installed sealing rubber ring in the one groove in installation process, has better joint water closure with regard to the joint that makes tubing like this, even under the situation of foundation settlement, also can effectively ensure the seal of whole pipeline, prevent inside and outside water body UNICOM.Because adopting, the utility model adds the reinforced concrete construction of steel cylinder, thus can resist sizable external pressure load, and also construction cost is relatively low.

Cylinder type Framework Of Steel Reinforcement in the utility model can also can form for being installed by individual layer circumferential reinforcement and longitudinal steel bar for installing the cylinder type Framework Of Steel Reinforcement pipe cage that forms by two-layer circumferential reinforcement and longitudinal steel bar by bearing rod.
