Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of engineering construction, concretely relates to a water seepage prevention structure based on engineering construction. BACKGROUND

[0002] In engineering construction, drainage pipeline is one of the indispensable structures. In the rough house completed, the water pipe will reserve a certain length upward, and the waterproof layer will be laid or brushed on the pouring layer, and the waterproof layer will generally wrap the outer bottom of the water pipe upward. Because the later needs to lay the ceramic tile or other ground panel material, the upward wrapping of the water pipe waterproof layer has good waterproof effect, and generally this water pipe is used for the drainage of commonly used drainage equipment such as wash basin and closestool;

[0003] When the water pipe is used as a floor drain, a construction hole needs to be opened downward around the water pipe to facilitate the installation of the floor drain later, but this is also related to the thickness of the concrete layer of the ceramic tile. If the concrete layer is thick, it can also not need to open the construction hole downward, but most families need it because the floor drain is generally used in the kitchen and toilet. In the design of general families, the ground of the kitchen and toilet needs to be slightly lower than the ground height of other houses to avoid water overflow in the kitchen and toilet to other houses. If the ground of the kitchen and toilet is higher, the ground of other houses will be higher, and the laying cost of the thickened concrete layer will be better, so the construction hole needs to be opened, and the water pipe needs to be cut to make the top of the water pipe flush with the bottom of the construction hole, which inevitably causes the original waterproof layer to be damaged. At present, the efficient construction method is to open the construction hole and cut the water pipe first, lay the concrete layer and then paste the ceramic tile, cut the ceramic tile and reserve the hole for installing the floor drain, and finally install the floor drain. When installing the floor drain, the gap between the construction hole and the outside of the floor drain is generally filled by the leak stopper, but this also causes the waterproof layer not to be directly connected with the water pipe, and the waterproof effect of the cross section of the waterproof layer is not good. In actual construction, different construction workers have different work details, and workers with rough work will directly dig holes or openings by electric hammer to finally open the construction hole. The construction of the electric hammer will cause the waterproof structure of the cross section of the waterproof layer to be damaged, the cross section is uneven, and the waterproof effect is not good. Therefore, when the water flows directly into the water pipe, no seepage phenomenon occurs. Because the concrete layer does not have a waterproof effect, when there is long-term water accumulation, the water will penetrate downward from the gap between the waterproof layer and the leak stopper, finally causing the seepage phenomenon.

[0027] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model, apparently, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the protection scope of the utility model.

[0028] like Figures 1-6 As shown:

[0029] A seepage-proof structure based on engineering construction includes a casting layer 1 cast around a water pipe 2, a waterproof layer 3 fixed to the surface of the casting layer 1, and a concrete layer 4 covering the waterproof layer 3. A seepage-proof structure 8 fixed to the surface of the waterproof layer 3 is installed between the casting layer 1 and the concrete layer 4.

[0030] The seepage prevention structure 8 includes a seepage prevention surface 81, a seepage prevention pipe 82, and a connecting part 83. The seepage prevention surface 81 and the seepage prevention pipe 82 are connected by the connecting part 83. The lower surface of the seepage prevention surface 81 is fixed to the waterproof layer 3, and the seepage prevention pipe 82 extends to the inside of the water pipe 2.

[0031] In engineering construction, two drainage pipes are an essential structural element, such as... Figure 1 As shown, in the completed unfinished house, the water pipe 2 will have a certain length reserved upwards, and a waterproof layer 3 will be laid or coated on the poured layer 1. The waterproof layer 3 will generally wrap around the bottom outer side of the water pipe 2. Because tiles 5 or other flooring materials need to be laid later, the waterproof layer 3 wrapping around the water pipe 2 has a better waterproof effect. Generally, this type of water pipe 2 is used for drainage of commonly used drainage equipment such as washbasins and toilets.

[0032] When using water pipe 2 as floor drain 7, construction holes 9 need to be drilled downwards around water pipe 2 to facilitate the later installation of floor drain 7. However, this is also related to the thickness of the concrete layer 4 used to lay tiles 5. If the concrete layer 4 is thick, it may not be necessary to drill downwards to create construction holes 9, but most households do. This is because floor drain 7 is commonly used in kitchens and toilets. In general home designs, the floors of kitchens and toilets need to be slightly lower than the floors of other rooms to prevent water from overflowing into other rooms. If the floors of kitchens and toilets are higher, then other rooms... The ground surface will be higher, and laying a thicker concrete layer 4 will be more cost-effective. Therefore, it is generally necessary to drill a construction hole 9 and cut the water pipe 2 so that the top of the water pipe 2 is flush with the bottom of the construction hole 9. This inevitably damages the original waterproof layer 3. The most efficient construction method is to first drill the construction hole 9 and cut the water pipe 2, then lay the concrete layer 4 and then tile 5. The tile 5 is cut and a hole is reserved for installing the floor drain 7. Finally, the floor drain 7 is installed. When installing the floor drain 7, the gap between the construction hole 9 and the outside of the floor drain 7 is generally filled with a sealant 6 (such as...). Figure 2The waterproof layer 3 is not directly connected with the water pipe 2, and only the waterproof layer 3 at the section is blocked by the waterproof plug 6, so that the waterproof effect is poor. In actual construction, different construction workers have different work details. Workers with rough work will directly dig holes or holes by using an electric hammer to finally complete the opening of the construction hole 9. The construction of the electric hammer will cause the waterproof structure of the waterproof layer 3 at the section to be damaged, and the section is uneven, so that the waterproof effect is poor. When water flows directly into the water pipe 2 during normal use, no seepage phenomenon occurs. Since the concrete layer 4 does not have a waterproof effect, when there is long-term water accumulation, the water will penetrate downward from the gap between the waterproof layer 3 and the waterproof plug 6 through the concrete layer 4, and finally the seepage phenomenon occurs;

[0033] The anti-seepage structure 8 is installed after the construction hole 9 is opened. The anti-seepage surface 81 of the anti-seepage structure 8 can be fixed to the surface of the waterproof layer 3 by using waterproof glue. The waterproof layer 3 and the anti-seepage structure 8 are in surface-to-surface contact, so that the waterproof effect is improved, and a stable waterproof structure is formed. The installation method is simple and fast, and does not bring complicated installation steps to construction workers, so that workers generally accept it.

[0034] After the anti-seepage structure 8 is installed, the subsequent steps of laying the concrete layer 4 and the ceramic tile 5 are the same as the conventional construction method.

[0035] In an optional embodiment, the anti-seepage structure 8 is made of hard PVC material.

[0036] In this embodiment, the hard PVC material is more convenient to install. The outer surface of the anti-seepage pipe 82 can be directly in contact with the inner surface of the water pipe 2, so that a stable installation effect can be obtained.

[0037] In an optional embodiment, the anti-seepage structure 8 is made of flexible rubber material.

[0038] In this embodiment, because the structure after the construction hole 9 is opened is not very flat, the flexible rubber material can better adapt to different working environments, and the sealing connection effect of the anti-seepage surface 81 and the waterproof layer 3 is better.

[0039] In an optional embodiment, the anti-seepage surface 81 and the connecting portion 83 are made of flexible rubber material, and the anti-seepage pipe 82 is made of hard PVC material.

[0040] In this embodiment, because the structure after the construction hole 9 is opened is not very flat, the anti-seepage surface 81 and the connecting portion 83 are made of flexible rubber material, and the flexible rubber material can better adapt to different working environments. When the anti-seepage pipe 82 is made of hard PVC material, the installation of the anti-seepage pipe 82 is also convenient and stable, and the stability after connection is high.

[0041] In an alternative embodiment, the connecting portion 83 is made of flexible rubber material, and the impermeable surface 81 and the impermeable pipe 82 are made of hard PVC material.

[0042] In this embodiment, the connecting portion 83 is made of flexible rubber material, which can adapt to and fit the shape of the construction hole 9, and the installation of the floor drain 7 is more convenient in the later stage. When the impermeable pipe 82 is made of hard PVC material, the installation of the impermeable pipe 82 is also more convenient and stable. When the impermeable surface 81 is made of hard PVC material, the impermeable surface 81 is not prone to deformation due to storage extrusion.

[0043] In an alternative embodiment, the impermeable pipe 82 is not provided with a hard ring 88 protruding inward at one end.

[0044] In this embodiment, when the impermeable pipe 82 is made of hard material, the impermeable pipe 82 is fitted with the inner wall of the water pipe 2, and has a certain resistance during installation. By setting the hard ring 88, the hard tool acts on the hard ring 88 to push the impermeable pipe 82 downward, and the installation is more convenient.

[0045] In an alternative embodiment, the connecting portion 83 is a concave structure matched with the construction hole 9.

[0046] In this embodiment, when the connecting portion 83 is made of hard material, the concave structure of the connecting portion 83 is beneficial to the installation of the floor drain 7.

[0047] In an alternative embodiment, the inner wall surface of the impermeable pipe 82 is connected with an elastic member 84 with one end open.

[0048] In this embodiment, when the impermeable pipe 82 is made of flexible material, it can adapt to different inner diameters of the water pipe 2, but the problem that follows is that when the water pipe 2 is blocked and the water is reversed, the impermeable pipe 82 may be pushed upward by the water. In order to avoid this situation, the elastic member 84 acts on the impermeable pipe 82 through the elasticity, so that the impermeable pipe 82 is tightly attached to the inner wall of the water pipe 2, and the connection is more stable and will not be caused by the reverse water.

[0049] In an alternative embodiment, the inner wall surface of the impermeable pipe 82 is provided with a ring-shaped groove, and the outer end surface of the elastic member 84 is provided with a groove-shaped structure matched with the ring-shaped groove.

[0050] In this embodiment, the ring-shaped groove and the groove-shaped structure matched with the ring-shaped groove can avoid the relative displacement of the elastic member 84 and the impermeable pipe 82, so as to avoid the elastic member 84 and the impermeable pipe 82 from falling off, and the connection strength is more stable.

[0051] In an alternative embodiment, the opening of the limiting groove 85 is fixedly connected with a reinforcing rod 86, the opening of the elastic member 84 is symmetrically provided with a mounting hole 87, and the adjacent side of the mounting hole 87 is closed by the reinforcing rod 86.

[0052] In the embodiment, due to the narrow installation space, the installation of the elastic member 84 is laborious, through the cooperation of the mounting hole 87 and the reinforcing rod 86, the installation of the elastic member 84 can be realized by using a clamp spring wrench or an equivalent tool, and the reinforcing rod 86 can better cope with the pressure applied by the clamp spring wrench to avoid damage to the elastic member 84.

[0053] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing embodiments of the present application are described in detail, for the skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
