Abstract
The utility model relates to a steel mouthing socket prestressed concrete pipe-jacking which consists of a mouthing, a socket, a reinforced skeleton frame and a concrete pipe core, wherein, the mouthing and the socket are respectively arranged at two ends of the concrete pipe core, and the reinforced skeleton frame is coaxially embedded in the concrete pipe core; a protective layer is poured on the outer wall of the concrete pipe core, and a layer of prestressed steel wire is winded on the outer wall of the concrete pipe core in the protective layer. The utility model has the advantages of very simple integral structure, scientific and reasonable design, good durability, impermeability and water seal capability of joint. The utility model is also of thin pipe wall, low construction cost, thereby greatly reducing the construction and transportation cost, thereby being a steel mouthing socket prestressed concrete pipe-jacking with high innovation.
Description
Technical field
The utility model relates to concrete plug, especially a kind of faucet concrete ceiling coil with steel.
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.
Equal coaxial two-layer Framework Of Steel Reinforcement of setting-in in the tube core of available coagulation soil push pipe causes tube core thicker, and 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.
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 faucet concrete ceiling coil with steel that convenient construction, tube wall are thin.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of faucet concrete ceiling coil with steel; 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 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.
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 packed 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. 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 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.
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 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.
5. 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 faucet concrete ceiling coil with steel of a kind of novelty.
