Abstract

The invention discloses a processing method for preventing water leakage at contact position of a polyvinyl chloride (PVC) tube and a concrete floor slab. An outer wall of the PVC tube is grinded coarsely so as to facilitate bonding of the PVC tube and concrete, microdilatancy fine aggregate concrete and a secondary pouring process are adopted, a cracking phenomenon is decreased, and water leakage is effectively prevented.

Description

The preventing water leakage processing method of a kind of pvc pipe material and concrete floor slab contacting point

Technical field

The present invention relates to the construction and installation field, in particular to the preventing water leakage processing method of a kind of pvc pipe material and concrete floor slab contacting point.

Background technique

In building engineering, general elder generation goes out agent structure by concreting, and then lays various upper and lower conduits road is installed, and will be the pipeline preformed hole hole at floor during concreting, and pipeline carries out the shutoff slit with concrete after passing preformed hole again.The present multiselect pvc pipe of pipeline material, but pvc pipe material outer wall is smooth, and outer wall contacts easily cracking with concrete, cause leaking, and therefore to the occasion of waterproof requirement is arranged, does not also have now a kind of good method for waterproofing to solve above-mentioned seepy question.

Summary of the invention

The preventing water leakage processing method that the purpose of this invention is to provide a kind of pvc pipe material and concrete floor slab contacting point, the method can effectively reduce the cracking of pvc pipe material outer wall and concrete joint synapsis, thereby effectively prevents from leaking.

For achieving the above object, the present invention takes following technological scheme:

The preventing water leakage processing method of a kind of pvc pipe material and concrete floor slab contacting point comprises the steps:

(a) the pvc pipe material is installed, is made the pvc pipe material pass the concrete floor slab preformed hole;

(b) with 100 purpose sand paper the outer wall of pvc pipe material is polished to coarse in the position of passing preformed hole, the roughness coefficient is 3.2, the position range that the outer wall of pvc pipe material is polished is from the concrete floor slab bottom surface to the concrete floor slab upper surface, and upwards prolongs 1/2nd of pvc pipe material radius again;

(c) lower limb in described polishing position contacts around the pvc pipe material sealing annular template of installation and with the sealing of concrete floor slab bottom surface, then pour into the microdilatancy pea gravel concreten to the slit between pvc pipe material and the concrete floor slab, and the height that makes the microdilatancy pea gravel concreten is 2/3rds of thickness of concrete floor, then left standstill 24 hours, and removed annular template;

(d) on above-mentioned microdilatancy pea gravel concreten, continue to add the microdilatancy pea gravel concreten to the top edge of described polishing position, and make microdilatancy pea gravel concreten upper surface be the upper surface that the gradient drops to concrete floor slab, then left standstill 24 hours.

The technical program is coarse with pvc pipe material outer wall polishing, being conducive to adopting simultaneously the microdilatancy pea gravel concreten with concrete bonding, and the technique that adopts secondary to build, reduced the generation of cracking phenomena, effectively prevent from leaking.

Description of drawings

Fig. 1 is the structural representation after the conventional method water-proofing treating;

Structural representation after Fig. 2 the inventive method water-proofing treating.

Embodiment

Below in conjunction with accompanying drawing, the present invention will be further described:

Structure after the tradition preventing water leakage disposal methods as shown in Figure 1, the method is that annular template is sealed on the bottom surface of pvc pipe material 2 and concrete floor slab 1, then directly pour into pea gravel concreten 3 and equal with the upper surface of concrete floor slab 1, this kind processing method makes between pea gravel concreten 3 and the pvc pipe material 2 and very easily ftractures, and leaks thereby cause.

Operating procedure of the present invention is as follows:

As shown in Figure 2, pvc pipe material 2 is installed, is made pvc pipe material 2 pass the preformed hole of concrete floor slab 1; Then with 100 purpose sand paper the outer wall of pvc pipe material 2 is polished, until coarse, the roughness coefficient of degree of roughness is 3.2, the concrete position range that the outer wall of pvc pipe material is polished is the upper surface 6 from the bottom surface 7 of concrete floor slab 1 to concrete floor slab 1, and then upwards prolonging 1/2nd of pvc pipe material radius, this position range is the pvc pipe material 2 outer walls height 4 of being polished namely; Lower limb in the polishing position is installed annular template and is contacted (not drawing annular template among Fig. 2) with bottom surface 7 sealings of concrete floor slab 1 around 2 sealings of pvc pipe material, then pour into microdilatancy pea gravel concreten 3 to the slit between pvc pipe material 2 and the concrete floor slab 1, and the height that makes microdilatancy pea gravel concreten 3 be concrete floor slab 1 thickness 2/3rds, then left standstill 24 hours, and removed afterwards annular template; On above-mentioned microdilatancy pea gravel concreten 3, continue to add microdilatancy pea gravel concreten 5 top edges to described polishing position, and the upper surface that makes microdilatancy pea gravel concreten 5 is the upper surface 6 that the gradient drops to concrete floor slab, then leaves standstill and namely finishes processing procedure in 24 hours.

After said method is processed, pvc pipe material 2 and microdilatancy pea gravel concreten 3, microdilatancy pea gravel concreten 5 are not easy to crack, even pvc pipe material 2 and microdilatancy pea gravel concreten 3 crackings, also have being connected between pvc pipe material 2 and the microdilatancy pea gravel concreten 5 that the secondary guarantee is provided, so effectively realized the preventing water leakage requirement.
