Description
Technical field
The utility model relates to concrete plug, especially a kind of steel cylinder strengthened steel faucet prestressed concrete ceiling coil.
Background technique
The region that push pipe generally is applied under the specific geographical environmental condition as the operation that is difficult to slot, construction environment are had relatively high expectations, do not caused surface subsidence, as: the underground construction of railway, highway below.Concrete ceiling coil is the general non pressure pipe that adopts when using as waste pipe, and this push pipe easy concrete to the concrete ceiling coil mouth of pipe in construction and installation such as correction process causes breakage, thereby influences the sealability of joint; Especially when pressure line is carried out jacking construction, cause is jacking pressure tubing directly, therefore concrete ceiling coil that need caliber is enough big carries out jacking earlier as sleeve pipe, and setting pressure pipeline in sleeve pipe has then strengthened the construction comprehensive cost of concrete ceiling coil thus.
All install coaxial two-layer Framework Of Steel Reinforcement in the tube core of available coagulation soil push pipe, cause tube core thicker, its main cause is that concrete pipe need bear high external pressure load due to the construction earthing and the high inner pressuring load due to the fed sheet of a media.The concrete ceiling coil own wt of this structure is heavier, and the cost of raw material is higher, and production time is longer, needs the lifting crane gear of high tonnage to install, and has improved the cost of transportation and the construction cost of concrete ceiling coil greatly for this reason.In addition, the Watertightness of available coagulation soil push pipe pipeline is also undesirable.
Concrete ceiling coil is mainly used in the draining field, its main cause at present: 1. body carrying external pressure load and internal water pressure are limited; 2. the impermeability of tube wall is not high; 3. joint socket joint Watertightness is relatively poor, studied carefully its above-mentioned cause influence concrete ceiling coil the feedwater field application.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of steel cylinder strengthened steel faucet prestressed concrete ceiling coil is provided, and this concrete ceiling coil is simple in structure, and withstand voltage, corrosion-resistant, impermeability and joint water closure are good, comprehensive cost is low, and convenient construction and tube wall are thinner.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of steel cylinder strengthened steel faucet prestressed concrete ceiling coil; constitute by bellmouth, socket, 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 Framework Of Steel Reinforcement; it is characterized in that:, be wound with one deck reinforcement wire being perfused with on this concrete pipe outer core on protective layer and the concrete pipe outer core in this protective layer at the coaxial respectively steel cylinder that installs of the bellmouth and the spigot of this concrete pipe in-core.
And described Framework Of Steel Reinforcement is cylindrical reinforcing bar cage.
And described Framework Of Steel Reinforcement is two coaxial cylindrical reinforcement frame pipe cages that form that install by bearing rod of coaxial cylindrical reinforcing bar cage.
And described cylindrical reinforcing bar cage is installed by circumferential reinforcement and longitudinal steel bar and forms.
And described Framework Of Steel Reinforcement is coaxial to be embedded on the bellmouth and socket of concrete pipe in-core, perhaps is packed in the inboard or the outside of bellmouth and socket.
And described protective layer is a concrete.
Advantage of the present utility model and beneficial effect are:
1. the tube core of this concrete ceiling coil adopts the one-piece casting moulding, the Framework Of Steel Reinforcement that the concrete pipe in-core is inlayed is an individual layer, therefore can effectively reduce the thickness of tube core tube wall, thereby alleviate the own wt of whole push pipe, make things convenient for transportation and construction, greatly reduced the cost of transportation and construction.
2. the bellmouth of this concrete pipe in-core and the coaxial respectively steel cylinder that installs of spigot, two steel cylinders that this bellmouth and socket place install have strengthened the impermeability of integrated piping, for the safe transport pressured fluid provides guarantee.
3. be perfused with on the tube core outer wall of this concrete ceiling coil on protective layer and the concrete pipe outer core in this protective layer and be wound with one deck reinforcement wire, this structure has improved whole body and has resisted external pressure load and interior ability of pressing; And in its socket groove sealing rubber ring can be installed in the installation process, and this just makes this tubing have good joint water closure, and the opposing uneven settlement is very capable.
4. 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.
5. the concrete tube core of this concrete ceiling coil pours into one deck concrete cover outward in addition; the alkaline environment that provides by concrete cover; protect cylindrical reinforcement frame and reinforcement wire effectively, improved the antiseptic property of tubing, prolonged the tubing life-span.
6. the utility model overall structure is very simple, design science is reasonable, have favorable durability, impermeability, joint water closure, and tube wall is thin, engineering cost is low, greatly reduce construction and cost of transportation, is the higher steel cylinder strengthened steel faucet prestressed concrete ceiling coil of a kind of novelty.
