A kind of new waterproof sleeve pipe
Technical field
The utility model relates to a kind of Lock gate of engineering construction, particularly a kind of new waterproof sleeve pipe.
Background technique
In engineering construction, traditional water string, usually adopts single-stage steel pipe as sleeve pipe, directly fills spunyarn, finally smear waterproof coating cream.When clogging spunyarn, spunyarn often can not be fixed in sleeve pipe preferably, usually landing, causes shutoff not tight; When high temperature, waterproof coating cream just can melt, and then causes waterproof coating cream to run off.These problems all can cause pipeline seepage.
Model utility content
The purpose of this utility model is that, for a kind of new waterproof sleeve pipe, make when clogging waterproof and sealing material, waterproof and sealing material can be fixed in sleeve pipe preferably.
The technical solution of the utility model is as follows:
A kind of new waterproof sleeve pipe, comprises pipe box joint and waterproof portion composition.Described pipe box joint forms by two-stage body is fixedly sleeved; the port of the first order body that bore is less is in the inside of the larger second level body of bore; form body containing space between described first order body and second level body, and form stationary platen at first order body port; Described waterproof portion is arranged on stationary platen.
Preferably, in described new waterproof sleeve pipe, described waterproof portion is combined by fixing part, oil resistance portion and waterproof coating, and three is successively set on the stationary platen in body solute space.
Preferably, in described new waterproof sleeve pipe, by plastic deformation tight fit connection between described first body and the second body.
Preferably, in described new waterproof sleeve pipe, the arranged outside of described first pipe end has termination to become large plane of inclination gradually inwards, the inner side of the second body establishes internal diameter to become large plane of inclination gradually inwards by termination, and the plane of inclination outside the first body cooperatively interacts with the plane of inclination inside the second body and is connected.
Preferably, in described new waterproof sleeve pipe, described fixing part and oil resistance portion are arranged in body containing space, and waterproof coating 80% is positioned at body containing space, and 20% is positioned at termination, body solute space.
Preferably, in described new waterproof sleeve pipe, described fixing part is made by spunyarn.
Preferably, in described new waterproof sleeve pipe, described oil resistance portion is made by dry ash.
Preferably, in described new waterproof sleeve pipe, described waterproof coating is that waterproofing unction makes.
Beneficial effect: the plane of inclination outside the first body cooperatively interacts with the plane of inclination inside the second body and is connected, and makes connection more convenient, more closely.
Waterproof coating has part to be positioned at outside body solute space, arranges certain surplus, avoids the too fast loss of waterproof coating.
Waterproof coating spreads upon the outside in oil resistance portion, and when high temperature, can effectively prevent waterproof coating to run off because of melting, action time is lasting, prevents seepage.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment 1:
As shown in Figure 1, present embodiments provide a kind of new waterproof sleeve pipe, comprise pipe box joint and waterproof portion composition.Described pipe box joint forms by two-stage body is fixedly sleeved, the port of the first order body 5 that bore is less is in the inside of the larger second level body 6 of bore, the arranged outside of described first pipe end has termination to become large plane of inclination gradually inwards, the inner side of the second body establishes internal diameter to become large plane of inclination gradually inwards by termination, and the plane of inclination outside the first body cooperatively interacts with the plane of inclination inside the second body and is connected.By plastic deformation tight fit connection between first body and the second body.Form body containing space between described first order body 5 and second level body 6, and form stationary platen 4 at first order body 5 port; Described waterproof portion is arranged on stationary platen 4.Waterproof portion is combined by fixing part, oil resistance portion and waterproof coating, wherein fixing part has spunyarn 3 to make, oil resistance portion is made by dry ash 2, waterproof coating is that organic oil 1 forms, and wherein spunyarn 3 directly contacts with stationary platen 4, spunyarn 3 is arranged dry ash 2, dry ash 2 is arranged machine oil 1, spunyarn 3 and dry ash 2 are arranged in body containing space, and machine oil 180% is positioned at body containing space, and 20% is positioned at termination, body solute space.
Embodiment 2:
Embodiment 2 is with the difference of embodiment 1, and the first body in embodiment 2 and the surface of contact of the second body do not arrange plane of inclination, and the external diameter of the first body is more bigger than the internal diameter of the second body, and the two is by plastic deformation tight fit connection.Fixing part has spunyarn 3 to make, oil resistance portion is made by dry lime, waterproof coating is made up of dubbin, wherein spunyarn 3 directly contacts with stationary platen 4, spunyarn 3 is arranged dry ash 2, dry lime arranges waterproof coating, spunyarn 3 and dry lime are arranged in body containing space, waterproof coating 80% is positioned at body containing space, and 20% is positioned at termination, body solute space.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection domain that all should belong to the utility model claims.
