Abstract

The utility model relates to an antiseeping casing, belonging to the field of the pipe fitting. The antiseeping casing is applied to water prevention on the node that the pipeline passes through the concrete board position. The casing is a section of tubular component sheathed at the node position. The upper end of the tubular component is combined on the periphery of the opening of the pipeline on the concrete board, and the lower end of the tubular component is combined into integration with the pipeline. The leakage substances flow into a hollow cavity between the casing and the pipeline through the periphery of the pipeline, and enter into the pipeline through the small holes on the wall of the pipeline, and therefore, the purpose of preventing leakage and seepage is reached.

Description

Antiseeping casing

The utility model has related to a class leakage proof sleeve pipe.Metal conduit accessory field.

At present, metal or plastic tube pass the concrete plate, adopt the way of installing behind the reserving hole.Node processing can be divided into first service sleeve, back bushing burying, three kinds of forms of no sleeve pipe.When these node processing are used for waterproof, then exist many shortcoming and defect, become the hidden danger of seepage.Analyze its reason, from the material aspect, plastic tube and concrete binding ability are relatively poor and to collapse temperature influence big, and cement or concrete be because solidification shrinkage, its secondary junction and be prone to microcrack with the tubing junction; Wearing out of waterproof sealing materials such as ointment; From the design and construction aspect, constructing lack of standardization is to cause main cause of seepage, moreover be exactly design unreasonable.Traditional node waterproof is handled, and briefly says, exactly based on " blocking up ".Its defective is conspicuous, takes the floor construction way of normally used squatting pan, block water fully and be difficult to accomplish from entering packed layer outside to inside.Water enter a certain amount of after, will be from outside seepages of weak part such as pipeline and concrete plate handing-over node place, metopes.The survey showed that for the seepage that 2072 houses that 100 the city 1988-1990 in the whole nation are completed according to the Ministry of Construction carry out: between bathe in the lavatory, the seepage of metope is more serious, the seepage between wherein bathe in the lavatory is than roofing also high (annotate: roofing is about 30%).Seepage makes troubles not only for people's life, is unfavorable for the harmony of neighborhood relationship, returns country and has brought economic loss.

Purpose of the present invention: remedy the deficiency that pipeline in the past passes concrete plate place node waterproof way,, adopt " blocking up " " to dredge " the design and construction means of combination,, solve the leakage problems that cause at these positions preferably with minimum cost in conjunction with the construction concrete condition.

Content of the present invention: this sleeve pipe is one section tubular member, and less than is 20 centimetres usually.Be installed in pipeline and concrete handing-over node place, be enclosed within outside the pipeline, the upper end is combined in the pipeline hole periphery on the concrete plate, following end periphery combines with pipeline, form cavity between sleeve pipe and the pipeline, when material at concrete and pipeline binding site during from the outside seepage of pipeline peripheral edge portion, the seepage material flows into the cavity of sleeve pipe and pipeline enclosure, aperture on tube wall enters in the pipeline again, thereby reaches the purpose of antiseepage leakproof.

Sleeve pipe adopts plastic materials or rubber material or metallic material to make.The back is installed, and it is parallel to section similar " eight " font, the bottleneck of conduit axis direction; Its section perpendicular to the conduit axis direction is mainly ring.

Sleeve pipe and pipeline combine branch two classes: a class is the integral type combination, when promptly manufacturing, with sleeve pipe and pipeline injection moulding or pour into one complete; Another kind of is the combined type combination, and promptly sleeve pipe is made separately, and during construction, a kind of by in wire connection, bonding, socket and spigot joint, four kinds of combining forms of rubber wrist butting is integrated sleeve pipe and interior duct ligation.Combining between sleeve pipe upper end and concrete plate or embedded part, with above-mentioned employing four kinds of combining forms identical, also can be directly be combined on concrete plate or the embedded part compressing by rubber or plastics class packing ring on the sleeve pipe.Degree of finish to the metallic conduit surface of wire connection, rubber wrist butting binding site will have certain requirement.

Cooperate the use of this sleeve pipe, should in the hole on the concrete plate, bury the ordinary casing that has water stop ring, water guiding ring underground, to strengthen antiseepage leakproof effect.

Maintenance can be stayed on sleeve pipe and establish an inspection socket for convenience.

Advantage of the present invention: be applicable to that each metalloid or plastic tube pass the node waterproof construction of concrete plate place.Do not need original pipe fitting is made any change; Easy construction, easy to repair; Antiseepage good leak-proof effect, expense are extremely cheap, have economic benefit and social benefit preferably.

Now be further described with an embodiment.

Fig. 1 is the squatting pan drain opening node waterproof way sectional schematic diagram that has adopted antiseepage leakproof sleeve pipe.

In concrete plate ［ 8 ］, pre-buried or after bury ordinary casing ［ 3 ］.After pipeline (2) installing and locating, by screw thread (4) joint form, the same pipeline in lower end (2) that will be enclosed within the outer sleeve pipe (1) of pipeline (2) combines.Sleeve pipe (1) upper end can select for use a section suitable for reading for the rubber-like packing ring (7) of " U " shape is embedded in sleeve pipe (1).Water enters in the pipeline (2) by the inclination aperture (5) on pipeline (2) wall after the hole place enters cavity between sleeve pipe (1) and the pipeline (2) again.

Inspection socket (6) is set up in maintenance for convenience; In order to improve the antiseepage leak preventing effect, can do one deck slush flashing (9) on the concrete plate (8).

Claims
