Description

Technical Field

[0001] The utility model relates to the technical field of waterproof structures, in particular to a novel waterproof structure for a covered soil roof. Background Art

[0002] When additional requirements for covering the roof with soil are imposed on a ground building, a layer of concrete protective layer is often added between the waterproof coiled material and the covered soil, and the load from the newly added covered soil and the concrete protective layer needs to be considered.

[0003] When the building cannot bear the load of the newly added covered soil and the concrete protective layer, a new covered soil waterproof structure has to be considered. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a novel waterproof structure that is applicable to effectively waterproofing the covered soil roof when the building load-bearing capacity cannot meet the requirement of adding a new layer of concrete protective layer.

[0005] To achieve the above purpose, the utility model is realized through the following technical solutions:

[0006] A novel waterproof structure for a covered soil roof, where the roof from bottom to top is successively concrete, primer, and waterproof coiled material. Two layers of high-density polyethylene are laid on the waterproof coiled material, a drainage board is laid on the two layers of high-density polyethylene, and covered soil is added on the drainage board.

[0007] Further, the corners of the roof are sealed with sealant and aluminum tape. The sealant is bonded to the joint seam at the corner, the aluminum tape is fixedly connected by screws to the end of the waterproof coiled material, and the aluminum tape itself is bonded to the bottommost concrete by sealant.

[0008] Further, the waterproof coiled material is two layers of asphalt membranes, one asphalt membrane has a thickness of 4 mm and the other asphalt membrane has a thickness of 5 mm.

[0009] Further, hot asphalt is sprayed on the primer.

[0010] Further, the drainage board is a corrugated drainage channel arranged evenly and side by side.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] The novel waterproof structure for a covered soil roof of the utility model has a reasonable structural design and material selection, is lightweight and sealed, is convenient for construction, has a good waterproof effect, and is a novel waterproof structure applicable to effectively waterproofing the covered soil roof when the building load-bearing capacity cannot meet the requirement of adding a new layer of concrete protective layer. Description of the Drawings

[0013] Figure 1It is a schematic diagram of the planar construction structure of the present utility model.

[0014] Figure 2 It is a schematic diagram of the construction structure at the corner of the present utility model.

[0015] Reference numerals: 1, concrete; 2, primer; 3, waterproof coiled material; 4, two layers of high-density polyethylene; 5, drainage board; 6, backfill soil; 7, sealant; 8, aluminum strip. Specific embodiments

[0016] Next, in conjunction with the accompanying drawings, the embodiments of the present utility model will be described in further detail.

[0017] As Figure 1 shown, a new waterproof structure for a backfill soil roof, the roof from bottom to top is successively concrete 1, primer 2 and waterproof coiled material 3. Two layers of high-density polyethylene 4 are laid on the waterproof coiled material 3 to replace the original concrete protection layer (one layer of geotextile, one layer of 4 cm thick concrete protection layer, one layer of high-density polyethylene). A drainage board 5 is laid on the two layers of high-density polyethylene 4, and backfill soil 6 is added on the drainage board 5.

[0018] As Figure 2 shown, at the corner of the roof, it is sealed with sealant 7 and aluminum strip 8. The sealant 7 uses polyurethane sealant. The sealant 7 is bonded to the joint seam at the corner. The aluminum strip 8 is fixedly connected by screws to the end of the waterproof coiled material 3, and the aluminum strip 8 itself is bonded to the bottommost concrete 1 by the sealant 7.

[0019] The waterproof coiled material 3 is two layers of asphalt membranes. The thickness of one asphalt membrane is 4 mm, and the thickness of the other asphalt membrane is 5 mm. The two asphalt membranes and the root-proof material together form the waterproof coiled material 3. Hot asphalt is sprayed on the primer 2 to achieve a better bonding effect.

[0020] The drainage board 5 is a corrugated drainage channel arranged uniformly and side by side. The laying area of the drainage board 5 is larger than the laying area of the backfill soil 6 to ensure that excess water can flow out through the drainage board 5, playing a waterproof role.

[0021] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the concept of the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as within the protection scope of the present utility model.
