Description

Technical Field

[0001] The invention relates to the technical field of roof waterproofing and heat preservation, and in particular to a waterproofing and heat preservation integrated construction process of roof post-grouting. Background Art

[0002] At present, many houses often leak during long-term use due to aging roofs, structural damage or poor construction quality, especially under extreme weather conditions, the leakage problem is more serious. In order to solve this problem, the traditional approach is usually to dismantle the original roof structure layer by layer, including the surface layer, protective layer, insulation layer and waterproof layer, and then re-construct and repair. However, this renovation method not only requires a lot of manpower and material resources, the cost is extremely high, and the construction period is long, resulting in the house being unable to be used normally during the maintenance period, seriously affecting the daily life and living environment of residents. In addition, the comprehensive demolition of the roof structure may also cause other secondary problems, such as damage to the original structure and the generation of construction waste. Therefore, the existing renovation methods are difficult to balance the cost, construction period and construction effect. There is an urgent need for a technology that can be constructed directly on the basis of the original roof to achieve fast and effective waterproof and thermal insulation repair. Summary of the invention

[0003] The purpose of the present invention is to provide a waterproof and thermal insulation integrated construction process for roof post-grouting to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above object, the present invention provides the following technical solution: a waterproof and thermal insulation integrated construction process of roof post-grouting, comprising the following steps:

[0005] S1. Arrange the positions of holes based on the original roof construction;

[0006] S2. After completing the hole location planning using a drilling machine, use standard drilling equipment to perform precise drilling operations;

[0007] S3, using a special grouting machine and grouting liquid to perform pressure grouting into the pre-drilled holes;

[0008] S4. After the grouting operation is completed, the sealing process begins after the slurry is fully solidified and reaches the predetermined strength standard;

[0009] S5. Clean the sealing area and its surrounding surfaces to ensure that there is no dust, oil or other debris to improve the adhesion of the coating;

[0010] S6. Apply waterproof coating on the surface layer, and evenly apply it on the sealing hole and roof surface according to the construction requirements;

[0011] S7. Conduct a 48-hour water-tightness test to verify the overall effectiveness of the waterproofing and thermal insulation system.

[0012] Preferably, the holes in step 1 are arranged in a plum blossom shape.

[0013] Preferably, the drilling depth in step 2 is between 10 mm and 25 mm.

[0014] Preferably, the grouting pressure of the grouting machine in step three is 0.2 MPa to 0.5 MPa.

[0015] Preferably, the height of the sealing portion in step 4 is consistent with the flatness of the roof.

[0016] Preferably, the waterproof coating in step six needs to be applied in multiple layers, and each layer of coating is applied after it dries before the next layer is applied.

[0017] Compared with the prior art, the invention has the following beneficial effects: the invention does not need to dismantle the original roof structure, and the construction is carried out directly on the original foundation, which not only reduces the renovation cost, but also shortens the construction period. Through grouting, the leaking roof structure is integrated, achieving the integrated effect of waterproofing and heat preservation, further improving the service life and comfort of the roof, thereby greatly improving the construction efficiency and economic benefits, and reducing the damage to the original structure of the roof. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 1 It is a process flow chart of the present invention. DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1 The present invention provides a waterproof and thermal insulation integrated construction process of roof post-grouting, comprising the following steps:

[0021] S1. Arrange the positions of holes on the basis of the original roof construction; ensure that the selection of hole positions will not affect the overall bearing capacity and stability of the roof, and fully consider the integrity of the roof waterproof layer to avoid arranging holes at key nodes or weak points;

[0022] S2. After completing the hole location planning using a drilling machine, use standard drilling equipment to perform precise drilling operations;

[0023] S3. Use special grouting machine equipment and grouting liquid to perform pressure grouting into the pre-drilled holes; ensure that the grouting liquid is evenly distributed in the holes and fully fills the holes and the gaps around them;

[0024] S4. After the grouting operation is completed, the sealing process begins after the slurry is fully solidified and reaches the predetermined strength standard; fill and seal the holes according to the standard to ensure that the density of the sealed part is consistent with the flatness of the roof;

[0025] S5. Clean the sealing area and its surrounding surfaces to ensure that there is no dust, oil or other debris to improve the adhesion of the coating;

[0026] S6. Apply one coat and two coats of Lanshield weather-resistant waterproof coating on the surface layer, and apply it evenly on the sealing holes and the roof surface according to the construction requirements. During construction, attention should be paid to the uniform thickness of the coating, and no omissions or too thin coating should be allowed;

[0027] S7. Conduct a 48-hour water-tightness test to verify the overall effectiveness of the waterproofing and thermal insulation system.

[0028] Specifically, the holes in step one are arranged in a plum blossom shape. The plum blossom shape arrangement ensures that each hole is evenly distributed relative to the surrounding holes by staggered arrangement, effectively improving the coverage density and uniformity after grouting. This arrangement not only optimizes the distribution of waterproof materials, but also enhances the coverage effect of thermal insulation materials, avoiding waterproof blind spots and thermal insulation dead corners that are prone to occur in traditional parallel or symmetrical arrangements, thereby improving the waterproof and thermal insulation performance of the overall construction process. At the same time, the plum blossom shape arrangement can effectively reduce the stress concentration of the roof structure caused by uneven hole distribution, and ensure the stability and durability of the roof after construction.

[0029] Specifically, the drilling depth in step 2 is between 10 mm and 25 mm.

[0030] Specifically, the grouting pressure of the grouting machine in step three is 0.2MPa to 0.5MPa.

[0031] Specifically, the height of the sealing portion in step 4 is consistent with the flatness of the roof.

[0032] Specifically, the waterproof coating in step six needs to be applied in multiple layers, and the next layer can be applied after each layer of coating is dry.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
