Description

Technical Field

[0001] This invention relates to the field of basement waterproofing construction technology, and in particular to a basement waterproofing protection system and construction method. Background Technology

[0002] As modern buildings become increasingly taller, their foundations also become deeper, making waterproofing of basement exterior walls a more prominent issue. Under current technology, the main problems are as follows:

[0003] Although there are many types of waterproofing materials for basements, they are all flexible materials, which are easily damaged during the backfilling process, so a protective layer is required.

[0004] The current practice is to paste extruded polystyrene board and then build a brick wall protective layer. Because the brick wall is too high, it is prone to collapse. Therefore, the brick wall construction and backfilling need to be carried out alternately, which results in a long construction period, long waterproofing exposure time, and the risk of damage.

[0005] At the external corner where the basement exterior wall meets the roof slab, the waterproofing needs to extend upwards by 300-500mm. In many construction sites, the protection at this point is insufficient, causing the waterproofing membrane to age and be damaged, resulting in potential leakage. When waterproofing the basement roof slab, the waterproofing layer needs to be extended downwards by a certain width. Therefore, the external corner cannot be completed in one go when applying the external wall waterproofing protective layer, and the external corner must be protected first.

[0006] Therefore, this patent proposes a solution to address the aforementioned technical problems and improve the performance of the basement exterior wall waterproofing system. This solution can enhance the protective effect of the waterproofing layer while ensuring ease of construction and environmental friendliness. Summary of the Invention

[0007] This invention addresses the shortcomings of existing technologies by developing a basement waterproofing protection system and construction method. It can provide better protection for the waterproofing layer, especially at the external corners, reducing the construction costs associated with re-treating the external corner waterproofing layer due to damage. The recyclable external corner protection board greatly reduces construction costs.

[0008] The technical solution of this invention to solve the technical problem is as follows: a basement waterproofing protection system, including a basement exterior wall, a waterproof layer, a basement roof slab, and multiple corner protection plates. The waterproof layer is laid on the outside of the basement exterior wall and extends up to the upper surface of the basement roof slab by 300-500mm. The corner protection plates are arranged on the outside of the waterproof layer and at the corner where the basement exterior wall and the basement roof slab meet. The corner protection plate has an L-shaped longitudinal section and includes a first protection plate and a second protection plate. The first protection plate is in close contact with the basement roof slab, and the second protection plate is in close contact with the basement exterior wall.

[0009] Preferably, the corner protection plate is made of plastic steel; the corner protection plate has a buckle and a slot at both ends along its length; the buckle of the corner protection plate can engage with the slot of the adjacent corner protection plate.

[0010] Preferably, the outer side of the waterproof layer is provided with multiple protective plates and a lightweight aggregate concrete protective layer, which are an integrated structure. The integrated structure of the protective plates and the lightweight aggregate concrete protective layer is laid on the outer side of the basement exterior wall, with the lower part of the integrated structure laid to the level of the basement floor slab and the top part laid to a position 300mm away from the top elevation of the basement roof slab.

[0011] Preferably, the protective plate is provided with connecting protrusions and connecting grooves on opposite sides; the connecting protrusions on the protective plate can engage with the connecting grooves on adjacent protective plates.

[0012] A method for waterproofing and protecting the exterior walls of a basement, wherein the construction of the basement waterproofing and protection system includes the following steps:

[0013] Step 1: Clean the waterproof layer on the outside of the basement walls and remove surface impurities;

[0014] Step 2: Clean and level the bottom of the outer side of the basement wall;

[0015] Step 3: Lay the integrated structure of protective board and lightweight aggregate concrete protective layer. The integrated structure of protective board and lightweight aggregate concrete protective layer is laid on the outside of the basement exterior wall. The lower part of the integrated structure is laid to be flush with the basement floor slab, and the top is laid to a certain distance from the basement roof slab. When laying the integrated structure of protective board and lightweight aggregate concrete protective layer, the inner side of the protective board is tightly attached to the waterproof layer.

[0016] Step 4: Install corner protection boards at the external corner where the basement exterior wall meets the basement roof slab. Place the first protection board tightly against the basement roof slab and the second protection board tightly against the basement exterior wall. Multiple corner protection boards are connected together in sequence by buckles and slots.

[0017] Step 5: Backfill the outer side of the basement exterior wall with soil, backfilling and compacting in layers until the bottom of the corner protection board is reached;

[0018] Step Six: When waterproofing the basement roof slab, remove the corner protection boards before proceeding with the waterproofing work. After the top waterproofing is completed, protect the exposed waterproof layer on the outer top of the basement exterior wall with an integrated structure consisting of a protective board and a lightweight aggregate concrete protective layer before backfilling. The corner protection boards are removed and then recycled.

[0019] Preferably, the leveling work in step two uses cement mortar for leveling.

[0020] As a preferred embodiment, the specific steps for the integrated structure of laying the protective board and lightweight aggregate concrete protective layer in step three are as follows: the first integrated structure is laid by spot bonding. After the first integrated structure is laid, the connecting protrusions on the protective board of the second integrated structure are inserted into the connecting grooves on the protective layer of the first integrated structure. After assembly, the second integrated structure is pasted on the outside of the basement exterior wall by spot bonding, and so on. The top is laid up to 300mm from the top elevation of the basement roof slab.

[0021] As a preferred option, when waterproofing the basement roof slab in step six, the top waterproofing layer extends a certain distance below the sun corner.

[0022] The effects described in the invention are merely those of the embodiments, and not all the effects of the invention. The above technical solutions have the following advantages or beneficial effects:

[0023] 1. This invention adopts an integrated structure of protective board and lightweight aggregate concrete, which is prefabricated in the factory, resulting in less material waste. It can reduce the time consumed by the traditional process of plastering the surface of the waterproof layer of the basement exterior wall, which can significantly shorten the construction period, save labor, and thus save costs.

[0024] 2. This invention allows for the overall construction of the protective layer of the waterproofing layer on the exterior wall of the basement, avoiding damage to the waterproofing layer caused by multiple constructions, avoiding secondary repairs, and reducing the risk of leakage;

[0025] 3. Corner protection boards are used to protect the external corners where the basement exterior walls meet the basement roof slab. This can prevent the waterproofing layer from aging, curling, or being damaged, and reduce the risk of leakage.

[0026] 4. The corner protection board is a recyclable device. It can be removed during the waterproofing construction of the basement roof slab, recycled and reused, which can reduce the investment in waterproofing protection measures and reduce construction costs.

[0027] 5. Lightweight aggregate concrete protective layers can prevent damage to the protective layer structure from large stones and sharp objects during backfilling construction, thus providing better protection. Attached Figure Description
