The utility model has the advantages of very simple integral structure, scientific and reasonable design, good durability, impermeability and water seal capability of joint, low construction cost, and great reduction of construction cost, thereby being a steel mouthing socket concrete pipe-jacking with high innovation.

Description

Steel faucet concrete ceiling coil

Technical field

The utility model relates to concrete plug, especially a kind of 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, and its socket is the F mouth of a concrete casting injection forming, 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, the joint water closure is good, comprehensive cost is low and the 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 faucet concrete ceiling coil, constitute by cylinder type Framework Of Steel Reinforcement and concrete tube core, the coaxial concrete pipe in-core that is embedded in of cylinder type Framework Of Steel Reinforcement, it is characterized in that: the two ends at the concrete tube core install bellmouth and socket respectively, the two ends of cylindrical reinforcement frame are packed in respectively on bellmouth and the socket, the coaxial annular groove that is shaped on the socket outer rim cylinder outside this concrete tube core.

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 cylindrical reinforcing bar cage of individual layer.

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

And coaxial made annular groove is 1～3 on the described socket outer rim cylinder outside the concrete tube core.

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 disposes cylinder type Framework Of Steel Reinforcement pipe cage at the concrete pipe in-core, so improved the resistance to pressure of whole body greatly, has improved external pressure load and the interior ability of pressing resisted.

2. adopt the flexible steel faucet structure, socket can be installed 1～3 sealing rubber ring in its annular 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 steel bellmouth and socket, has reduced the concrete shearing force damage of bellmouth and socket end face, has strengthened the sealability of whole pipeline.

4. the utility model overall structure is very simple, and design science is reasonable, has favorable durability, joint water closure, and engineering cost is low, has significantly reduced construction cost, is the higher 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.

This steel faucet concrete ceiling coil, constitute by cylinder type Framework Of Steel Reinforcement and concrete tube core 3, this cylinder type Framework Of Steel Reinforcement is by two coaxial cylinder type Framework Of Steel Reinforcement pipe cage type formulas that form that install by bearing rod 6 of coaxial cylinder type reinforcement cage, the cylinder type reinforcement cage is to be installed by circumferential reinforcement 4 and longitudinal steel bar 5 to form, install bellmouth 7 and socket 1 respectively at the two ends of concrete tube core, the two ends coaxial respectively installing (being generally welding) of cylinder type Framework Of Steel Reinforcement pipe cage are on bellmouth and socket, the inboard cylinder type reinforcement cage of cylinder type Framework Of Steel Reinforcement pipe cage is packed on bellmouth and the socket in the present embodiment, this cylinder type Framework Of Steel Reinforcement can coaxially be packed in the outer rim (as present embodiment) of the bellmouth and the socket of concrete pipe in-core, also can be packed in the inner edge of bellmouth and socket.The coaxial annular groove 2 that is shaped on the socket outer rim cylinder outside the concrete tube core, this annular groove are in 1～3 and its sealing rubber ring to be installed, and annular groove shown in the present embodiment accompanying drawing is 2.

The cylindrical reinforcement frame of this steel faucet concrete ceiling coil also can be the cylindrical reinforcing bar cage of individual layer.

The bellmouth and the socket of this concrete ceiling coil are steel, and the socket of bellmouth and adjacent push pipe adopts the sealing rubber ring sealing of being installed on the annular groove when installing mutually.

Joint socket of the present utility model is a flexible interface, socket all can be installed sealing rubber ring in two 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 the utility model adopts the skeleton form of cylinder type Framework Of Steel Reinforcement pipe cage, thus sizable external pressure load can be resisted, and also construction cost is relatively low.
