Description

Technical Field

[0001] The present invention relates to the technical field of ground waterproofing, and in particular to a building ground waterproofing system and a construction method. Background Art

[0002] There are multiple water sources in the bathroom, such as the washbasin, shower area, bathtub, etc. If no waterproofing treatment is performed, moisture will penetrate into structures such as walls, floors and ceilings, causing mold on the walls, deformation and falling of the floors, and even causing damage to the wall structure. The significance of bathroom waterproofing is to protect the building structure, maintain a sanitary environment, and ensure the health and safety of the residents. The traditional bathroom waterproofing process is to apply waterproof paint and then backfill the bathroom with construction slag or expanded clay. When backfilling construction slag, the slag often needs to be crushed and placed gently, otherwise it will damage the waterproof layer. If expanded clay is used for backfilling, the cost will be greatly increased; and the traditional bathroom waterproofing process generally formulates a secondary drainage structure, but the traditional secondary drainage layer does not have water diversion measures, and there is a problem of slow secondary drainage efficiency. Therefore, we propose a building ground waterproofing system and construction method. Summary of the invention

[0003] In view of the above technical problems in the related art, the present invention provides a building ground waterproofing system and a construction method, which can solve the above problems.

[0004] To achieve the above technical objectives, the technical solution of the present invention is implemented as follows: A building ground waterproof system and construction method, which comprises, from bottom to top, a ground base, a leveling water-conducting layer, a secondary waterproof layer, a ceramsite filling layer, a strong ground leveling layer, and a primary waterproof layer, a downpipe is provided through the middle of the ground base, a downpipe surface is provided with a downpipe hole, a through hole is vertically provided at the lowest point of the leveling water-conducting layer, the downpipe passes through the through hole, and the lowest point of the downpipe is horizontally aligned with the top of the through hole, the top of the downpipe is vertically connected with a drain pipe through a switching joint, and the drain pipe passes through the ceramsite filling layer, the strong ground leveling layer, and the primary waterproof layer in sequence; The construction method of the building ground waterproofing system specifically includes the following steps: S1: Clean the ground base 1, vertically anchor a number of steel bars on the surface of the ground base 1, and apply concrete according to the required slopes of the inclined ground layer A and the inclined ground layer B; S2: Apply the plugging paint at the intersection of the through hole at the bottom of the slope of the inclined ground layer A and the inclined ground layer B and the outer wall surface of the downpipe, and apply the secondary waterproof layer after the leveling water-conducting layer is completely dry; S3: Lay a ceramsite filling layer with a thickness of 8cm~10cm, lay a crushed stone layer or building slag ash to fill the surface of the ceramsite filling layer, and finally lay mortar for strong ground treatment to form a strong ground leveling layer. Apply leak-proof coating at the junction of the strong ground leveling layer and the outer wall surface of the drainage pipe; S4: Apply a waterproof layer once on the surface of the strong ground leveling layer.

[0005] Furthermore, the leveling water-conducting layer includes a bottom leveling layer and a top water-conducting layer, and the top water-conducting layer includes an inclined ground layer A symmetrically arranged left and right and an inclined ground layer B symmetrically arranged front and back, and the lowest points of the inclined ground layer A and the inclined ground layer B converge at the top of the through hole.

[0006] Furthermore, a water retaining ring is integrally formed at the bottom of the adapter, and after the downpipe and the adapter are matched, the bottom end of the water retaining ring is 5 cm lower than the height of the downhole.

[0007] Furthermore, the water retaining ring is in the shape of a funnel which is wide at the top and narrow at the bottom, and the diameter of the bottom end of the water retaining ring is three quarters of the diameter of the top end.

[0008] Furthermore, the slope of the inclined ground layer A is 10°~15°, and the top of the slope of the inclined ground layer B is located at the center height of the inclined ground layer A.

[0009] Beneficial effects of the present invention: The waterproof system of the present application adopts a combination of a leveling water-conducting layer, a secondary waterproof layer and a drainage hole to form a secondary drainage structure with high drainage efficiency. The double-layer waterproofing is combined with a fast-conducting secondary drainage, which can extend the life of the waterproof material and improve the waterproof grade; The combination of ceramsite filling layer and strong ground leveling layer can not only reduce the consumables required for filling, but also protect the secondary waterproof layer; The water retaining ring at the bottom of the adapter is used for offset drainage, preventing water from the drain pipe from easily overflowing from the drain hole, and avoiding the secondary waterproof layer from contacting moisture in advance. It can also extend the life of the waterproof material and improve the waterproof level. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The following will be combined with the accompanying 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 belong to the scope of protection of the present invention.

[0015] Embodiment 1: Figure 1-3 As shown, according to the present invention, a building ground waterproof system is disclosed, which includes, from bottom to top, a ground base layer 1, a leveling water-conducting layer 2, a secondary waterproof layer 7, a ceramsite filling layer 8, a strong ground leveling layer 9, and a primary waterproof layer 10. A downpipe 4 is arranged through the middle of the ground base layer 1. The downpipe 4 adopts a hard polyvinyl chloride pipe. A downpipe 401 is opened on the surface of the downpipe 4. The diameter of the downpipe 401 is 12 mm. A through hole 3 is vertically opened at the lowest point of the leveling water-conducting layer 2. The downpipe 4 passes through the through hole 3 and the lowest point of the downpipe 401 is parallel to the ground. The top of the through hole 3 is horizontally aligned, the leveling water-conducting layer 2 includes a bottom leveling layer and a top water-conducting layer, the top water-conducting layer includes an inclined ground layer A201 symmetrically arranged left and right and an inclined ground layer B202 symmetrically arranged front and back, the lowest points of the inclined ground layer A201 and the inclined ground layer B202 are both gathered at the top of the through hole 3, the secondary waterproof layer 7 on the surface of the leveling water-conducting layer 2 can prevent water from penetrating downward, and combined with the slope shape of the leveling water-conducting layer 2, quickly guide the water along the slope into the drain hole 401, and finally drain from the drain pipe 4; The top of the downpipe 4 is vertically connected to the drain pipe 6 through the adapter 5, and the drain pipe 6 passes through the ceramsite filling layer 8, the strong ground leveling layer 9, and the primary waterproof layer 10 in sequence; A water retaining ring 501 is integrally formed at the bottom of the adapter 5; The construction method of the building ground waterproofing system specifically includes the following steps: S1: Clean the ground base 1, vertically anchor several steel bars on the surface of the ground base 1, control the slope of the inclined ground layer A201 to be 10°, and the top of the slope of the inclined ground layer B202 is located at the center height of the inclined ground layer A201. Scrape concrete according to this requirement to ensure that the bottoms of the slopes of the inclined ground layers A201 and B202 are both collected at the lowest point of the drain hole 401. Wait until the inclined ground layers A201 and B202 solidify until no marks are left when stepped on, and proceed to the next step; S2: Apply a leak-proof coating to the intersection of the through hole at the bottom of the slope of the inclined ground layer A201 and the inclined ground layer B202 and the outer wall surface of the downpipe 4 to avoid leakage caused by gaps between the outer wall surface of the downpipe 4 and the through hole 3, and eliminate the hidden danger of water seepage. After the leveling water-conducting layer 2 is completely dry, apply a secondary waterproof layer 7; S3: Lay an 8cm thick ceramsite filling layer 8. The ceramsite has a round texture and can effectively protect the secondary waterproof layer 7. Lay a crushed stone layer or building slag ash to fill the surface of the ceramsite filling layer 8 to reduce the cost of filling materials. Finally, lay mortar for strong ground treatment to form a strong ground leveling layer 9. Apply a leak-proof coating at the junction of the strong ground leveling layer 9 and the outer wall surface of the drainage pipe 6. There is a gap between the strong ground leveling layer 9 and the drainage pipe 6 to cause water leakage, thereby eliminating the hidden danger of water seepage; S4: A waterproof layer 10 is applied once on the surface of the strong ground leveling layer 9.

[0016] Subsequently, the floor drain is installed and the floor tiles are laid. Under normal circumstances, water is drained through the drain pipe 6, the water retaining ring 501, and the downpipe 4. Even if there is a micro-leakage in the primary waterproof layer 10, the water can pass through the leveling water-conducting layer 2 and the downpipe hole 401 and finally be discharged from the downpipe 4.

[0017] In the preferred technical solution, after the downpipe 4 and the adapter 5 are matched, the bottom end of the water retaining ring 501 is 5 cm lower than the height of the downhole 401. The water retaining ring 501 is funnel-shaped, wide at the top and narrow at the bottom. The diameter of the bottom end of the water retaining ring 501 is three quarters of the diameter of the top end. The water retaining ring 501 is used for staggered drainage. When water flows out from the bottom end of the water retaining ring 501, it does not contact the downhole 401, preventing the water flow of the drainage pipe 6 from easily overflowing from the downhole 401.

[0018] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
