The overall structure of the utility model is quite simple; the design is scientific and reasonable; the utility model has good durability, permeability water-proof performance at the joint; the device is added with the ability of resisting external pressure and load capacity; the construction cost is comparatively low and the construction and operation are simple, which greatly reduces the construction cost.

Description

The steel faucet prestressed concrete pipe

Technical field

The utility model relates to concrete plug, especially a kind of steel faucet prestressed concrete pipe.

Background technique

In the present employed all kinds of concrete water transmission pipes of China, mainly contain the concrete drain tile of self-stressing concretes pipe, prestressed concrete pipe and other various interface forms according to classification, be mainly used in municipal administration, water conservancy, road and bridge, urban water supply system, industrial waterline, field irrigation, plant pipe network and dark earthing culvert pipe etc.Though these tubing can reach the purpose of water delivery to a certain extent, but exist some technological deficiencies: though 1. the self-stressing concretes pipe disposes the reinforcing bar of some in body, but the reexpansion and the transverse breakage that in use occur body easily, the maintenance maintenance difficulty is big, the running cost height; And its joint water closure is relatively poor, and the body impermeability is lower, and working life is shorter.2. prestressed concrete pipe repairing rate after its moulding is very high, and the maintenance maintenance cost is big, and the body own wt is heavier, directly influences the installation rate of site operation, and its impermeability is lower, and working life is shorter.3. the concrete drain tile of other interface shapes, its body weight is generally bigger, and because its interface shape mostly is a rigidity, so when the weak soil layer is constructed, be easy to produce the setting of ground phenomenon, cause tubing interface cracking and sewage to leak, therefore the workmen need carry out pre-pretreatment to ground for avoiding setting of ground, and this can make the cost of construction significantly improve, and has also increased the difficulty of construction.

Find a kind of product relevant by retrieval with the utility model, its product name is: prestress steel sleeve concrete pipe, accompany one deck sheet metal in the middle of the tube core of this pipe, though this product has good impermeability and soft interface, but its cost height, the shortcoming that especially long its cost of distance laying is high is more obvious.

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 and the joint water closure is good, long service life, the simple steel faucet prestressed concrete pipe of constructing operation.

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

This steel faucet prestressed concrete pipe; constitute by bellmouth, socket, concrete tube core, reinforcement wire, protective layer; wherein bellmouth and socket are packed in the two ends of concrete tube core respectively; reinforcement wire is wrapped on the concrete tube core wall; matcoveredn outside the reinforcement wire of concrete pipe outer core; it is characterized in that: at the coaxial setting-in one cylinder type Framework Of Steel Reinforcement of concrete pipe in-core; the two ends of this cylinder type Framework Of Steel Reinforcement install bellmouth and socket respectively, at the coaxial respectively thin-walled steel cylinder that is fixed with of the bellmouth and the socket inner edge of this concrete pipe in-core.

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

And described protective layer is a slush.

Advantage of the present utility model and beneficial effect are:

1. at concrete pipe in-core layout circle column type Framework Of Steel Reinforcement, make whole tube core become reinforced concrete construction, and its concrete pipe outer core is wound with reinforcement wire, this just makes tubing have very strong resistance to pressure, has improved the ability of resisting the external pressure load.

2. also be fixed with two hoop steel cylinders and being packed in respectively on bellmouth and the socket at the concrete pipe in-core, itself and the moulding of concrete tube core one-piece casting make this concrete plug have very high impermeability.

3. adopt flexible faucet structure, have good joint Watertightness, and this tube material and tube wall is thin, the body own wt is lighter, and the opposing uneven settlement is very capable.

4. the utility model overall structure is very simple, design science is reasonable, have favorable durability, impermeability, joint water closure, engineering cost is relatively low, maintenance maintenance is convenient and constructing operation is easy, greatly reducing construction cost, is the higher novel steel faucet prestressed concrete pipe 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.

The utility model is by bellmouth 7; socket 1; concrete tube core 6; reinforcement wire 8; protective layer 3 constitutes; wherein bellmouth and socket are packed in the two ends of concrete tube core respectively; reinforcement wire is wrapped on the concrete tube core wall; on the outer wall of tube core, spray cement mortar protective course; be inlaid with the cylinder type Framework Of Steel Reinforcement in the tube core; its two ends adopt welding manner to be packed on bellmouth and the socket respectively; the cylinder type Framework Of Steel Reinforcement is installed with forms such as colligation or welding by circumferential reinforcement 5 and longitudinal steel bar 4 and forms, and is inlaid with two thick thin-walled steel cylinders 2 of hoop 1.5mm is welded on respectively on bellmouth and the socket in tube core.

Joint socket of the present utility model is a flexible interface, has good Watertightness, even also can effectively ensure the seal of whole pipeline under the situation of foundation settlement, prevents that sewage from leaking.Because the utility model adopts reinforced concrete construction, so can resist sizable external pressure load, thickness of earth-fill cover is little in construction, reduced difficulty, the construction cost of construction, and maintenance maintenance is simply easy.
