Roof minimally invasive self-healing waterproof method

Abstract

The invention discloses a roof minimally invasive self-healing waterproof method. The method comprises the following steps that a grouting hole is formed in a floor cover plate and extends into a heat preservation layer; grouting is conducted on the to-be-repaired area of the heat preservation layer through the grouting holes; the mortar continues to be injected, and the mortar enters the space between the heat preservation layer and the waterproof layer along a leakage channel in the to-be-repaired area of the heat preservation layer and enters the space between the roof and the waterproof layer through cracks of the waterproof layer; the mortar enters the roof crack to complete plugging of the roof crack; the grouting holes are formed in the floor cover plate and the heat preservation layer, grouting is conducted in the grouting holes, repairing of a leakage channel in the to-be-repaired area of the heat preservation layer is completed, and the problem that time and labor are consumed due to the fact that a waterproof heat preservation structure is dismantled on a large scale is solved; in addition, mortar conveyed by means of the leakage channel can enter the cracks of the roof, then repairing of the cracks of the roof is completed, and the problem of roof leakage is solved through a minimally invasive means.

Description

technical field [0001] The invention relates to the technical field of building waterproofing, in particular to a minimally invasive self-healing waterproofing method for roofs. Background technique [0002] Roof waterproofing has always been a long-standing problem, similar to the world's problems; once it leaks, it is difficult to repair, and sometimes it is difficult to achieve results after trying all kinds of methods. It has brought a lot of troubles and influences. [0003] The existing waterproof structure system is as follows: roof membrane waterproof layer + perlite insulation layer + floor slab, but there are the following problems: [0004] 1) The coiled material is waterproof, and it is difficult to make it airtight, especially after a long time, some places are easy to void, and the water will leak out from the gap between the coiled material and the roof, and flow between the coiled material and the roof. When encountering cracks in the roof, water will seep ...

AI Technical Summary

Problems solved by technology

[0007] 4) The floor slab itself is a pressure plate, which cannot play the role of waterproofing

As pointed out in a kind of roof structure partition waterproof structure and its construction method with the publication number CN111535511A, the facilities in the leaking area are removed first, and then the follow-up roof crack repair work is carried out, the workload is large and the construction period is long. Time-consuming, and there is a risk of repeated water leakage; another example is that the roof leak detection and repair method based on polyurethane waterproof glue with the publication number CN108868028A is to directly remove other facilities on the roof, then find the leak point of the roof, and then use polyurethane Waterproof glue is used to block and then achieve the purpose of waterproofing. In essence, it also needs to dismantle the facilities in the leaking area, which also has the disadvantage of consuming a lot of manpower and material resources.

[0009] In order to solve the above problems, the present invention provides a roof minimally invasive self-healing waterproof method to solve the problem of poor repair effect and time-consuming and labor-intensive repairing methods of roof waterproofing in the past
