In order to solve one or more above-mentioned defects among the prior art, the utility model aims to solve the technical problem that a combination waterproof sleeve pipe is provided, this sleeve pipe simple structure, three sleeve pipe position is accurate, can realize whole location, makes the wall body after connecting tube, the wall body can not take place the infiltration simultaneously.

In order to achieve the above object, the utility model provides a combination waterproof sleeve, including drainage sleeve, the sleeve pipe of ventilating and ponding sleeve pipe, drainage sleeve, the sleeve pipe of ventilating and ponding sleeve pipe carry out fixed connection through the seal ring, the seal ring is in drainage sleeve pipe, the sleeve pipe of ventilating and ponding sheathed tube middle part, the seal ring comprises three crossing ring board.

Furthermore, three positioning holes are distributed on the water stop ring.

Furthermore, the water stop ring is also provided with a connecting plate at the intersection of the circular ring plates, and the positioning holes are formed in the connecting plate.

Furthermore, a central positioning ring is welded at one end of each of the drainage sleeve, the ventilation sleeve and the water accumulation sleeve, and water-swelling rubber is filled in each of the drainage sleeve, the ventilation sleeve and the water accumulation sleeve.

Furthermore, a layer of buffer rubber layer is coated outside the central positioning ring.

The utility model has the advantages that:

firstly, the sleeve is simple in structure, the positions of the three sleeves are accurate, the integral positioning can be realized, and meanwhile, the wall body is prevented from water seepage after being connected with a pipeline;

secondly, the three positioning holes are formed in the water stop ring, and the positioning steel bars penetrate through each positioning hole, so that the sleeve can be fixed and positioned accurately;

thirdly, since a central positioning ring is connected to each of the three sleeves, the pipeline and the sleeves can be positioned on the same axis.

FIG. 2 is a schematic view of the structure in another direction of the present invention (the side with the center positioning ring);

fig. 3 is a sectional view of the drain pipe according to the present invention.

In the figure: 1. a drainage sleeve; 2. a venting cannula; 3. a water accumulation sleeve; 4. a water stop ring; 5. positioning holes; 6. a connecting plate; 7. a central positioning ring; 8. a cushion rubber layer; 9. a drain pipe; 10. a breather pipe; 11. a water accumulating pipe; 12. a water-swellable rubber.

Detailed Description

The invention will be further explained with reference to the following figures and examples:

referring to fig. 1-3, the combined waterproof casing comprises a drainage casing 1, a ventilation casing 2 and a water accumulation casing 3, wherein the drainage casing 1, the ventilation casing 2 and the water accumulation casing 3 are fixedly connected through a water stop ring 4, the water stop ring 4 is positioned in the middle of the drainage casing 1, the ventilation casing 2 and the water accumulation casing 3, and the water stop ring 4 is composed of three intersected circular ring plates.

The utility model discloses the in-process when using is as follows, when buildding the reinforcing bar rack, fix this combination waterproof sleeve on the reinforcing bar rack, after the reinforcing bar rack builds and accomplishes, carry out the pouring of concrete, after concrete solidifies, waterproof sleeve just fixes among the concrete wall, at this moment, can pass drainage pipe 9 and drainage sleeve 1, breather pipe 10 passes ventilation sleeve 2, ponding pipe 11 passes ponding sleeve 3 can, because drainage sleeve 1, the position between ventilation sleeve 2 and ponding sleeve 3 is fixed through seal ring 4, so the positional relation of the three is just definite, only need at the concrete reinforcing bar net correct position installation this combination waterproof sleeve can, in addition, seal ring 4 can also play the water blocking effect except fixing three sleeve, even some steam has entered into between wall body and the sleeve pipe, due to the blocking of the water stop ring 4, the water stop ring can be prevented from being immersed on the outer wall body.

Furthermore, three positioning holes 5 are distributed on the water stop ring 4. In order to make the utility model discloses a position is more accurate when fixing on the reinforcing bar rack for waterproof sleeve pipe, and it has three locating hole 5, specific to distribute on stagnant water ring 4, in order to guarantee stagnant water ring 4's stagnant water effect, the utility model discloses a stagnant water ring 4 still has connecting plate 6 in ring plate intersection department, locating hole 5 is seted up on connecting plate 6. When the sleeve is fixed, a positioning steel bar can pass through each positioning hole 5 of the water stop ring 4, and the three positioning steel bars can realize the combined positioning of the combined sleeve, so that the combined sleeve cannot shake.

Furthermore, the one end of drainage sleeve pipe 1, sleeve pipe 2 and ponding sleeve pipe 3 of ventilating still welds central holding ring 7, it has water-swelling rubber 12 to fill in drainage sleeve pipe 1, sleeve pipe 2 and the ponding sleeve pipe 3 of ventilating. In order to prevent the infiltration from appearing in the space between sleeve pipe and the pipeline, the diameter of pipeline is generally less than sheathed tube diameter, so that fill water-swelling rubber 12 between sleeve pipe and pipeline, and simultaneously, in order to make the location that the pipeline can be accurate at sheathed tube middle part, make the two coaxial, at drainage sleeve 1, the one end of sleeve pipe 2 and ponding sleeve pipe 3 still welds central holding ring 7 of ventilating, the sleeve pipe passes the centre bore on central holding ring 7 and can realize the location, in addition, in order to prevent that expend with heat and contract with cold and cause the pipeline damaged, it has one deck cushion rubber layer 8 to wrap at central holding ring 7, cushion rubber layer 8 has the ductility, even the expansion appears in the pipeline, also can not broken.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
