Abstract

The invention discloses a waterproof structure with a pipeline penetrating through a concrete floor. The waterproof structure comprises a process hole pre-formed in the floor and fine concrete filled in the process hole after a pipeline is mounted, wherein the process hole is formed by sleeving two or more sectional conical hole parts which are different in size and coaxial; both of the conical holes arranged vertically adopt structures that the upper parts are bigger and the lower parts are smaller; the larger end of the lower sectional conical hole extends into the upper sectional conical hole; the sleeving parts of the two conical holes are connected integrally through a bevel step of which the inner part is higher and the outer part is lower. According to the waterproof structure, the fine concrete can be filled between the process hole and the pipeline after the mounted pipeline is fixed; after the fine concrete solidifies, the built-in bevel step is formed; the bevel step can not only prevent the fine concrete from shrinking radially and axially, but also can form a labyrinth water stopping structure so as to ensure the leakproofness of the floor; the waterproof structure can be used for a water feeding pipeline to penetrate through the concrete floor, and can also be suitable for a wireway, an air channel and the other pipelines to penetrate through the concrete floor.

Description

Pipeline runs through concrete floor waterproof construction

Technical field

The present invention relates to a kind of house floor gap waterproof construction, specifically, the present invention relates to a kind of pipeline and run through concrete floor waterproof construction.

Background technique

In construction engineering, when concreting flooring, keep supplying the technique hole that drainage pipeline passes by design attitude is reserved, after upper and lower conduit road is in place, tamp with pea gravel concreten the technique hole that fills vacancy more afterwards.Technique hole majority reserved in construction engineering is cylindrical hole, also accidental up big and down small cone-shaped hole, and the technique hole of these shapes is simple in structure, make easily, after tamping, can accomplish the vacancy between effective plugging technology hole and pipeline.But, the technique hole of prior art is because lacking radially limit structure and axially waterproof construction, so on the flooring of residential building, reserved technique hole is tamped rear majority and is had seepage problem in reality, its reason is accessible contraction when tamping the pea gravel concreten that fills the later stage and solidifying, cause pea gravel concreten and concrete floor and pipeline junction to have micro-gap, once flooring ponding, water is seeped into downstairs along micro-gap, and excessive infiltration must cause neighbourhood's dispute.

Summary of the invention

There is seepage problem mainly for prior art in the present invention, proposes a kind of pipeline simple in structure, that construction is easy, leakage-proof effect is good and run through concrete floor waterproof construction.

The present invention is achieved through the following technical solutions technical goal.

Pipeline runs through concrete floor waterproof construction, and it comprises technique hole reserved on flooring, and the pea gravel concreten tamping after pipe laying in technique hole.Its improvements are: described technique hole is not waited by least two joint sizes and coaxial conical bore part is socketed to form, the perpendicular conical bore of putting is up big and down small structure, the large end of conical bore of next joint stretches in a pitch circle taper hole, two conical bore suit places are positioned at middle part, and both link into an integrated entity by low inside and high outside incline bench.

In said structure, cone angle alpha=30 in technique hole ⁰～60 ⁰.On technique hole, the large end radius of next pitch circle taper hole of small end radius ratio of a pitch circle taper hole is large, both semidiameter B=10mm～30mm, and the large end of next pitch circle taper hole stretches in a pitch circle taper hole small end, coincidence amount h=15mm～25mm.

The present invention compared with prior art, has following good effect:

1, technique hole is connected to form by the good luck axle of conical bore one of different size, and simple in structure, the demoulding is easy, does not increase difficulty of construction;

2, pea gravel concreten tamps between technique hole and pipeline, and the incline bench that solidifies rear formation plays and stops the radial and axial contraction of pea gravel concreten, significantly reduces the gap of flooring really, between pipeline and pea gravel concreten, is conducive to leakage proof;

3, save up and down between the conical bore of fit and connect by incline bench, form mazy type water sealing structure after the pea gravel concreten tamping solidifies, leakage proof is effective.

Embodiment

Below with reference to the accompanying drawings and in conjunction with the embodiments, the invention will be further described.

Embodiment 1

Pipeline shown in Fig. 1 runs through mixed Tulou face waterproof construction, and it comprises technique hole 1.1 reserved on flooring 1, and the pea gravel concreten 2 tamping after mounting pipe 3 in technique hole 1.1.The present embodiment runs through the waterproof construction of concrete floor, supporting pipeline 3 external diameter 32mm for residence building water supply pipeline.In the time building flooring 1, by the hole of reserved technique shown in Fig. 2 1.1, because flooring 1 thickness is 120mm, belong to conventional thickness.These technique hole 1.1 use two joint sizes do not wait and coaxial conical bore part is socketed to form, and the perpendicular two pitch circle taper holes of putting are up big and down small structure.Be in the long 60mm of conical bore of next joint, cone angle 40 ⁰, small end radius 25mm, holds greatly the about 46.8mm of radius.Be in the long 75mm of conical bore of a joint, cone angle 45 ⁰, the large end radius of conical bore of next joint of small end radius ratio of going up as shown in Figure 3 a pitch circle taper hole is large, both semidiameter B=10mm.The large end of conical bore of next joint extend in a pitch circle taper hole, coincidence amount h=15mm, and two conical bore suit places are positioned at middle part, and both link into an integrated entity by low inside and high outside incline bench.Technique hole 1.1 in the present invention is basic components, and it is connected to form by the good luck axle of conical bore one of different size, and it is easy that flooring 1 is built the rear demoulding, do not increase difficulty of construction.After the pipeline 3 of installing in technique hole 1.1 is fixing, can between technique hole 1.1 and pipeline, tamp pea gravel concreten 2, pea gravel concreten 2 solidifies the built-in incline bench of rear formation, play and stop the 2 radial and axial contractions of the solidifying soil of microlith mud, significantly reduce the gap between flooring 1 and pea gravel concreten 2, be conducive to leakage proof.Be to connect by incline bench between the conical bore of upper and lower fit on the other hand, after the pea gravel concreten tamping solidifies, form mazy type water sealing structure, guarantee non-leakage.

Embodiment 2

Fig. 4 is the embodiment of the present invention 2 structural representations, shows that auxiliary hole 1.1 is not waited by 4 joint sizes and coaxial conical bore part is socketed to form in figure, and this embodiment is for the thicker occasion of flooring 1.The present embodiment, because junction between technique hole 1.1 and concrete is provided with 3 incline benches, that is to say and be provided with 3 road mazy type water sealing structures, and its water leakage performance is further strengthened.In addition other good effect is identical with embodiment 1.
