Description

Technical Field

[0001] The present application relates to the technical field of waterproof engineering, and in particular to a waterproof layer structure at the bottom of a pool. Background Art

[0002] A pool is a small naturally formed pit filled with water or a water storage facility built with artificial materials and has an anti-seepage function.

[0003] A Chinese patent with announcement number CN203924842U discloses a waterproof structure for a large pool, including a resin primer arranged on a concrete base of the pool, on which a resin putty leveling layer, a glass fiber cloth layer, and an epoxy resin topcoat layer are sequentially arranged.

[0004] During the use of the above technology, since the main body of the pool is concrete, which is greatly affected by temperature changes, overcooling and overheating will cause the concrete to crack, and then cause the resin primer, resin putty leveling layer, glass fiber cloth layer, and epoxy resin topcoat layer to crack, thereby causing the pool to leak, which has shortcomings. Utility Model Content

[0005] In order to improve the water leakage problem of the pool, the present application provides a waterproof layer structure at the bottom of the pool.

[0006] The waterproof layer structure at the bottom of a pool provided in this application adopts the following technical solution:

[0007] A waterproof layer structure at the bottom of a pool comprises a pool body, wherein a waterproof coating is arranged on the inner wall of the pool body, and a crack repairing component for filling cracks on the pool body is arranged between the waterproof coating and the pool body, wherein the crack repairing component automatically fills the cracks on the pool body.

[0008] By adopting the above technical solution, when the pool body is not cracked, the waterproof coating on the pool body is in an intact state, and the pool body stores water normally. When the pool body is cracked, the waterproof coating can no longer prevent the water in the pool body from flowing out. At this time, the crack repair component on the pool body automatically fills the cracks on the pool body, thereby reducing the loss of water in the pool body.

[0009] Optionally, the crack repair component includes a concrete leveling layer arranged between the waterproof coating and the pool body, a plurality of crack repair belts with internal hollows are arranged in the concrete leveling layer, the middle part of the crack repair belt is easily broken under tension, an elastic membrane is arranged in the crack repair belt, the edge of the elastic membrane is fixed on the crack repair belt, the crack repair belt is filled with a crack repair agent, and the crack repair agent is located on the side of the elastic membrane facing the inner wall of the pool body.

[0010] By adopting the above technical solution, when cracks occur in the pool body and the cracks on the pool body drive cracks in the concrete leveling layer, the cracks in the concrete leveling layer break the crack repairing belt, and the elastic membrane is exposed to the water pressure inside the pool body. The elastic membrane is affected by the water pressure inside the pool body and squeezes the crack repairing agent into the cracks in the concrete leveling layer and the cracks on the pool body, thereby repairing the cracks and reducing further expansion of the cracks. At the same time, the elastic membrane prevents water inside the pool body from flowing out through the cracks.

[0011] Optionally, the crack repairing agent includes a highly water-absorbent resin, and cement powder is mixed in the highly water-absorbent resin.

[0012] By adopting the above technical solution, the super absorbent resin will absorb moisture in the air in the cracks and expand rapidly. The expanded super absorbent resin quickly fills the cracks. At the same time, the expanded super absorbent resin provides a water source for the cement powder and drives the cement powder to fill the cracks. The cement powder absorbs moisture on the super absorbent resin and undergoes a chemical reaction, gradually solidifying to repair the cracks, thereby achieving the effect of automatic crack repair.

[0013] Optionally, a plurality of hooks are provided on the crack repairing belt, and the hooks are used to be fixed in the concrete leveling layer.

[0014] By adopting the above technical solution, the hook claws on the crack repairing belt are conducive to better tearing the crack repairing belt when the concrete leveling layer cracks, so that the crack repairing agent in the crack repairing belt can overflow faster.

[0015] Optionally, the pool body includes a concrete base layer, and a steel mesh is arranged in the concrete base layer.

[0016] By adopting the above technical solution, the structural strength of the pool body is strengthened by the steel mesh, thereby reducing the possibility of cracking of the pool body or the degree of cracking.

[0017] Optionally, a connecting branch is provided on the pool body, and the connecting branch is used to be fixed in the concrete leveling layer.

[0018] By adopting the above technical solution, connecting the tree branches is conducive to fixing the concrete leveling layer on the pool body, while strengthening the structural strength of the concrete leveling layer and reducing the possibility of cracks in the concrete leveling layer.

[0019] Optionally, a gravel layer is provided at the bottom of the pool body, a rammed earth layer is provided at the bottom of the gravel layer, a clay layer is provided around the pool body, and a foam board is provided between the clay layer and the pool body.

[0020] By adopting the above technical scheme, the compressive strength of the soil at the bottom of the pool body is strengthened by the crushed stone layer and the rammed earth layer, and the possibility of cracks caused by uneven force on the bottom of the pool body is reduced. The foam board has the function of heat preservation and buffering, which reduces the influence of temperature changes on the pool body. At the same time, the pressure of the clay layer around the pool body acts on the foam board, causing the foam board to deform to a certain extent, thereby reducing the influence of the pressure of the clay layer on the pool body, which is beneficial to reducing the possibility of cracks on the side wall of the pool body.

[0021] Optionally, the waterproof coating includes a polyurethane coating and a polymer hydraulic mortar waterproof layer, and the polymer hydraulic mortar waterproof layer is located between the polyurethane coating and the concrete leveling layer.

[0022] By adopting the above technical scheme, polyurethane has anti-seepage and heat-insulating properties, thereby improving the waterproofness of the side wall of the pool body. The heat-insulating effect is beneficial to reducing the influence of temperature changes on the pool body. The polymer hydraulic mortar has anti-seepage properties, which can further improve the waterproofness of the pool body.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. When the pool body is not cracked, the waterproof coating on the pool body is intact and the pool body stores water normally. When the pool body is cracked, the waterproof coating can no longer prevent the water in the pool body from flowing out. At this time, the crack repair component on the pool body automatically fills the cracks on the pool body, thereby reducing the loss of water in the pool body;

[0025] 2. When cracks occur in the pool body, and the cracks on the pool body drive cracks in the concrete leveling layer, the cracks in the concrete leveling layer break the crack repairing belt, and the elastic membrane is exposed to the water pressure inside the pool body. Under the action of the water pressure inside the pool body, the elastic membrane squeezes the crack repairing agent into the cracks in the concrete leveling layer and the cracks on the pool body, thereby repairing the cracks and reducing the further expansion of the cracks. At the same time, the elastic membrane prevents the water inside the pool body from flowing out through the cracks;

[0026] 3. The super absorbent resin absorbs the moisture in the air in the crack and expands rapidly. The expanded super absorbent resin quickly fills the crack. At the same time, the expanded super absorbent resin provides a water source for the cement powder and drives the cement powder to fill the crack. The cement powder absorbs the moisture on the super absorbent resin and reacts chemically, gradually solidifying to repair the crack, thereby achieving the effect of automatic crack repair;

[0027] 4. The compressive strength of the soil at the bottom of the pool body is strengthened by the crushed stone layer and the rammed earth layer, reducing the possibility of cracks due to uneven force on the bottom of the pool body. The foam board has the function of heat preservation and buffering, reducing the influence of temperature changes on the pool body. At the same time, the pressure of the clay layer around the pool body acts on the foam board, causing the foam board to deform to a certain extent, thereby reducing the influence of the pressure of the clay layer on the pool body, which is beneficial to reduce the possibility of cracks on the side wall of the pool body.

[0033] The following is combined with Figure 1-4 This application is described in further detail.

[0034] The embodiment of the present application discloses a waterproof layer structure at the bottom of a pool.

[0035] Reference Figure 1 A waterproof layer structure at the bottom of a pool includes a pool body 1, a gravel layer 6 is laid at the bottom of the pool body 1, a rammed earth layer 7 is laid at the bottom of the gravel layer 6, a clay layer 8 is buried around the pool body 1, a foam board 9 is arranged between the clay layer 8 and the pool body 1, the pool body 1 includes a concrete base 101, a steel mesh 102 is pre-embedded in the concrete base 101, and is cast by a conventional installation template method.

[0036] Workers first tamp the soil at the location where the pool is to be built to form a rammed earth layer 7, and then spread a layer of crushed stone on the rammed earth layer 7 to form a crushed stone layer 6, and then tie a steel mesh 102 on the crushed stone layer 6 and install a casting mold, and then pour concrete to make the steel mesh 102 pre-buried in the concrete base 101 formed by the concrete. After the concrete solidifies, the casting mold is removed, and then foam boards 9 are pasted around the pool body 1, and the clay layer 8 is backfilled to press the foam boards 9 against the pool body 1.

[0037] Reference Figure 1 , Figure 2 and Figure 3 A waterproof coating 2 is arranged on the inner wall of the pool body 1, and a crack repair component 3 for filling cracks on the pool body 1 is arranged between the waterproof coating 2 and the pool body 1. The crack repair component 3 automatically fills the cracks on the pool body 1. The crack repair component 3 includes a concrete leveling layer 31 arranged between the waterproof coating 2 and the pool body 1, and a plurality of connecting branches 5 are bolted to the pool body 1.

[0038] Reference Figure 2 , Figure 3 and Figure 4 The connecting branch 5 is used to be embedded in the concrete leveling layer 31. A plurality of hollow crack repairing strips 32 are arranged in the concrete leveling layer 31. A plurality of hooks 4 are bonded to the crack repairing strips 32. The hooks 4 are used to be embedded in the concrete leveling layer 31. The crack repairing strips 32 fill the inner wall of the pool body 1.

[0039] Reference Figure 2 , Figure 3 and Figure 4 The middle part of the crack repairing belt 32 is prone to rupture under tension, an elastic film 33 is arranged inside the crack repairing belt 32, the edge of the elastic film 33 is bonded to the inner wall of the crack repairing belt 32, and a large amount of crack repairing agent 34 is filled in the crack repairing belt 32. The crack repairing agent 34 is located on the side of the elastic film 33 facing the inner wall of the pool body 1, and the crack repairing agent 34 includes a highly absorbent resin 341, and cement powder 342 is mixed in the highly absorbent resin 341.

[0040] Drill holes on the inner wall of the pool body 1 and install the connecting branch 5, then stick the repair tape 32 to the inner wall of the pool body 1, and then install the casting mold to keep a certain distance between the inner wall of the pool body 1 and the casting mold, and then pour cement slurry to form a concrete leveling layer 31, so that the repair tape 32 and the connecting branch 5 are pre-buried in the concrete leveling layer 31, and the casting mold is removed when the concrete leveling layer 31 solidifies.

[0041] When the pool body 1 cracks and the cracks on the pool body 1 drive the concrete leveling layer 31 to crack, the cracks in the concrete leveling layer 31 tear through the crack repairing tape 32, exposing the elastic membrane 33 to the water pressure inside the pool body 1. The elastic membrane 33 is affected by the water pressure inside the pool body 1, and squeezes the highly absorbent resin 341 and cement powder 342 into the cracks between the concrete leveling layer 31 and the pool body 1. At the same time, the elastic membrane 33 prevents water in the pool body from flowing into the cracks.

[0042] The super absorbent resin 341 absorbs moisture in the air in the crack and expands rapidly. The expanded super absorbent resin 341 quickly fills the crack. At the same time, the expanded super absorbent resin 341 provides a water source for the cement powder 342, and the cement powder 342 is also pushed by the super absorbent resin 341 to fill the crack. The cement powder 342 absorbs moisture on the super absorbent resin 341, undergoes a chemical reaction, and gradually solidifies to repair the crack.

[0043] Reference Figure 1 , Figure 2 and Figure 3 The waterproof coating 2 includes a polyurethane coating 201 and a polymer hydraulic mortar waterproof layer 202 , and the polymer hydraulic mortar waterproof layer 202 is located between the polyurethane coating 201 and the concrete leveling layer 31 .

[0044] The worker applies the polymer hydraulic mortar waterproof layer 202 on the solidified concrete leveling layer 31 , waits for it to solidify, and then sprays the polyurethane coating 201 on the solidified polymer hydraulic mortar waterproof layer 202 .

[0045] The implementation principle of the waterproof layer structure at the bottom of a pool in an embodiment of the present application is as follows: workers first tamp the soil at the location where the pool needs to be built to form a rammed earth layer 7, and then lay a layer of crushed stone on the rammed earth layer 7 to form a crushed stone layer 6, and then tie a steel mesh 102 on the crushed stone layer 6 and install a casting mold, and then pour concrete so that the steel mesh 102 is pre-buried in the concrete base 101 formed by the concrete, and after the concrete solidifies, the casting mold is removed, and then foam boards 9 are pasted around the pool body 1, and the clay layer 8 is backfilled to press the foam boards 9 tightly against the pool body 1.

[0046] Drill holes on the inner wall of the pool body 1 and install the connecting branch 5, then stick the repair tape 32 to the inner wall of the pool body 1, and then install the casting mold to keep a certain distance between the inner wall of the pool body 1 and the casting mold, and then pour cement slurry to form a concrete leveling layer 31, so that the repair tape 32 and the connecting branch 5 are pre-buried in the concrete leveling layer 31, and the casting mold is removed when the concrete leveling layer 31 solidifies.

[0047] When the pool body 1 cracks and the cracks on the pool body 1 drive the concrete leveling layer 31 to crack, the cracks in the concrete leveling layer 31 tear through the crack repairing tape 32, exposing the elastic membrane 33 to the water pressure inside the pool body 1. The elastic membrane 33 is affected by the water pressure inside the pool body 1, and squeezes the highly absorbent resin 341 and cement powder 342 into the cracks between the concrete leveling layer 31 and the pool body 1. At the same time, the elastic membrane 33 prevents water in the pool body from flowing into the cracks.

[0048] The super absorbent resin 341 absorbs moisture in the air in the crack and expands rapidly. The expanded super absorbent resin 341 quickly fills the crack. At the same time, the expanded super absorbent resin 341 provides a water source for the cement powder 342, and the cement powder 342 is also pushed by the super absorbent resin 341 to fill the crack. The cement powder 342 absorbs moisture on the super absorbent resin 341, undergoes a chemical reaction, and gradually solidifies to repair the crack.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
