Description

The steel faucet concrete ceiling coil of band steel cylinder

Technical field

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

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.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, withstand voltage, corrosion-resistant and the joint water closure good, comprehensive cost is low, the steel faucet concrete ceiling coil of the band steel cylinder of convenient construction.

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

The steel faucet concrete ceiling coil of this band steel cylinder, constitute by bellmouth, socket, cylinder type Framework Of Steel Reinforcement and concrete tube core, wherein bellmouth and socket are packed in the two ends of concrete tube core respectively, the coaxial concrete pipe in-core that is embedded in of cylinder type Framework Of Steel Reinforcement, it is characterized in that: at coaxial setting-in one steel cylinder of concrete pipe in-core, the two ends of this steel cylinder are packed in respectively on bellmouth and the socket.

And described cylinder type Framework Of Steel Reinforcement is for to install the cylinder type Framework Of Steel Reinforcement pipe cage that forms by circumferential reinforcement and longitudinal steel bar by bearing rod.

And, the coaxial inboard or the outside that is embedded in steel cylinder of described cylinder type Framework Of Steel Reinforcement pipe cage.

Advantage of the present utility model and beneficial effect are:

1. concrete tube core of the present utility model 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. adopt flexible faucet structure, 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. the utility model 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. steel cylinder of the present utility model 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 steel faucet concrete ceiling coil of the higher band steel cylinder 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.

Embodiment 1

The utility model is made of bellmouth 8, socket 1, cylinder type Framework Of Steel Reinforcement pipe cage 5 and concrete tube core 6, wherein bellmouth and socket are packed in the two ends of concrete tube core respectively, the coaxial concrete pipe in-core that is embedded in of cylinder type Framework Of Steel Reinforcement pipe cage, wherein at concrete pipe in-core setting-in one steel cylinder 2, the two ends of this steel cylinder are packed in respectively on bellmouth and the socket, and cylinder type Framework Of Steel Reinforcement pipe cage is embedded in the coaxial outside of steel cylinder.

Bellmouth of the present utility model and socket are steel, adopt the O-ring seal sealing during installation.

Wherein cylinder type Framework Of Steel Reinforcement pipe cage is to be formed by two coaxial installing by bearing rod 7 of cylinder type reinforcement cage, and the cylinder type reinforcement cage is to be installed by circumferential reinforcement 3 and longitudinal steel bar 4 to form.

Embodiment 2

The utility model is made of bellmouth, socket, cylinder type Framework Of Steel Reinforcement pipe cage and concrete tube core, wherein bellmouth and socket are packed in the two ends of concrete tube core respectively, the coaxial concrete pipe in-core that is embedded in of cylinder type Framework Of Steel Reinforcement pipe cage, wherein at concrete pipe in-core setting-in one steel cylinder, the two ends of this steel cylinder are packed in respectively on bellmouth and the socket, and cylinder type Framework Of Steel Reinforcement pipe cage is embedded in the coaxial inboard of steel cylinder.

Wherein cylinder type Framework Of Steel Reinforcement pipe cage is to be formed by two coaxial installing by bearing rod of cylinder type reinforcement cage, and the cylinder type reinforcement cage is to be installed by circumferential reinforcement and longitudinal steel bar to form.

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 plate, thus can resist sizable external pressure load, and also construction cost is relatively low.
