Abstract

The utility model provides a seepage resistant convenient concrete layer drainage pipe connecting embedding device which comprises a fixing seat, an upper connector, a lower connector, a seepage resistant groove and a seepage resistant ring. The embedding device is fixed through the fixing seat. The upper connector is adhered to the outer side of a drainage pipe located above a concrete pouring layer. The lower connector is adhered to the outer side of a drainage pipe located below the concrete pouring layer. The seepage resistant groove is formed in the outer edge of the bottom of the upper connector. The seepage resistant ring is arranged at the inner side of the lower connector. The seepage resistant convenient concrete layer drainage pipe connecting embedding device can solve the problem that water seepage occurs on a floor drainage pipe connecting portion and meanwhile greatly reduces construction cost.

Description

But a kind of portable type concrete layer drainage pipe of leakage proof connects pre-buried device

Technical field

The utility model relates to a kind of water-drainage tube part, but the portable type concrete layer drainage pipe that relates in particular to a kind of leakage proof connects pre-buried device.

Background technique

In many floor houses building, each residential customer sewage and rain water on roof mainly are after collecting through the plastic draining pipe network, to be discharged into the municipal wastewater pipe network, and in many floor houses building, the connection of each interlayer waste pipe just becomes the key that construction drainage connects.

The present practice is to adopt the method that presets concrete layer waste pipe passage, namely in the process of concrete cast, at embedding bore waste pipe such as a bit of in advance on the template layer, within the steel bar layer, for preventing that concrete blocks pre-buried waste pipe in the concrete placement, need the puffy volume group of sealing filling waste plastics bag, bag of cement and so in pre-buried waste pipe, after treating that concrete cast is finished and finalized the design, sealing filler is disclosed out, again pre-buried waste pipe is knocked out, just formed with external diameters such as waste pipe to be connected preset the waste pipe connecting passage; Hydropower installation personnel are when carrying out the installation of drainage pipe pipe fitting, waste pipe is vertically passed the drainage channel that concrete layer is reserved, realize that the solid between many floors waste pipe connects, there are two main drawbacks in this processing method, the one, the concrete layer reserved passageway is after fixing a drainpipe, often antiseepage leakproof treatment measures are improper, can cause floor drainage pipe joint percolating water to occur, increased contradiction between the floor gap user; Another is exactly the mode that adopts pre-buried formation concrete layer waste pipe passage, and the constructing operation flow process is more, need pre-buried, pour into a mould, remove pre-pipe laying, install, carry out leak-proof measure etc., labour cost is bigger.

The model utility content

The technical problems to be solved in the utility model is to provide a kind of problem that percolating water appears in floor drainage pipe joint that solves, and connects pre-buried device but the while has reduced the portable type concrete layer drainage pipe of the leakage proof of construction cost greatly.

But the utility model is achieved in that a kind of portable type concrete layer drainage pipe of leakage proof and connects pre-buried device, comprise fixed base, last connection mouth, following connection mouth, seepage-proof trough and leakproof ring, described pre-buried device is fixed by fixed base, last connection mouth is bonded in the waste pipe outside of concrete cast layer top, following connection mouth is bonded in the waste pipe outside of concrete cast layer below, seepage-proof trough is located at place, outer, connection mouth bottom, and the leakproof ring is located at down the inboard of connection mouth.

Be provided with the fixedly enhancing ring of some projectioies between described seepage-proof trough and the fixed base.

Described fixed base is provided with four fixed holes, by iron nail pre-buried device is fixed on the template, and the fixed base diameter is bigger than the diameter of last connection mouth and following connection mouth.

The described connection mouth of going up is tightly connected by glue bonding mode and waste pipe with following connection mouth.

But the portable type concrete layer drainage pipe of the utility model leakage proof connects pre-buried device following advantage is arranged: the key point of pre-buried device design of the present utility model be to have can with the drainage pipe binding function, before the concrete cast, pre-buried device is fixed on the template, after treating that the concrete cast finishes, pre-buried device and concrete layer form organic overall structure, pre-buried device outer wall closely is connected with concrete, inwall can be connected with waste pipe, need not form waste pipe again reserved passageway is installed, both solve the problem that percolating water appears in floor drainage pipe joint, reduced construction cost again greatly.

Description of drawings

In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.

But Fig. 1 is the cross-sectional view that the portable type concrete layer drainage pipe of the utility model leakage proof connects pre-buried device.

But Fig. 2 is the Facad structure schematic representation that the portable type concrete layer drainage pipe of the utility model leakage proof connects pre-buried device.

Embodiment

Come the utility model is described in detail below in conjunction with specific embodiment.

See also Fig. 1, shown in 2, but the portable type concrete layer drainage pipe that is a kind of leakage proof described in the utility model connects pre-buried device, comprise fixed base 1, last connection mouth 2, following connection mouth 3, seepage-proof trough 4 and leakproof ring 5, described fixed base 1 is provided with four fixed holes, by iron nail pre-buried device is fixed on the template 10, last connection mouth 2 is bonded in waste pipe 21 outsides of concrete cast layer 11 top, following connection mouth 2 is bonded in waste pipe 22 outsides of concrete cast layer 11 below, seepage-proof trough 4 is located at place, outer, connection mouth 2 bottom, leakproof ring 5 is located at down the inboard of connection mouth 3, is provided with the fixedly enhancing ring 6 of many projectioies between described seepage-proof trough 4 and the fixed base 1.

Fixed base 1 diameter is bigger than the diameter of last connection mouth 2 and following connection mouth 3, can guarantee that pre-buried device level and vertical direction in concrete cast layer are fixed simultaneously; The waste pipe 21 of last connection mouth 2 bonding concrete cast layers 11 top, the waste pipe 22 of following connection mouth 3 bonding concrete cast layers 11 below, make pre-buried device and concrete layer form organic whole, need not to remove, connection mouth and following connection mouth can be tightly connected by glue bonding mode and waste pipe again on the pre-buried device, have guaranteed that drainage pipe connection aspect is water-tight; Seepage-proof trough 4 except the same with fixed base 1 have guarantee that pre-buried device level and vertical direction in concrete layer are fixed simultaneously, also can prevent concrete top fluid gap leakage between connection mouth outer wall and the concrete layer from the pre-buried device; The design of leakproof ring 5 can prevent effectively that fluid is from the gap leakage between following connection mouth inwall and the waste pipe outer wall that is connected; The fixing effect that strengthens ring 6 is to strengthen fixedlying connected between pre-buried device and the concrete, increases the frictional resistance between concrete and the pre-buried device outer wall, is strengthening between pre-buried device and the concrete further reducing the probability of fluid leaks in the formation organic whole.
