Description

Technical Field

[0001] This utility model belongs to the field of basement anti-seepage, and relates to an anti-seepage underground floor protection structure. Background Technology

[0002] A basement is a room whose floor level is more than half the height of the room below the outdoor ground level. Multi-story and high-rise buildings require deeper foundations. To utilize this height, a basement is built under the ground floor of the building, which can increase the usable area and save backfill soil. It is economical and can improve the efficiency of building land use. Some high-rise building foundations are very deep. Making full use of this depth to build a basement has both economic and usability benefits.

[0003] However, basements face problems such as building settlement and groundwater infiltration, leading to waterproofing failure and easy seepage or even leakage, affecting people's normal lives and even causing safety accidents. When the rammed earth layer settles, the asphalt waterproofing layer of the waterproofing layer combines with other layers, causing the waterproof membrane to break and leading to water seepage in the basement floor, resulting in waterproofing failure. Therefore, a waterproofing layer structure with high structural strength and a certain degree of ductility is needed. Utility Model Content

[0004] The purpose of this utility model is to provide a seepage-resistant underground floor protection structure, which adopts a composite waterproof membrane layer of asphalt material laid on copper foil, and sets a special joint structure between adjacent composite waterproof membrane layers. The spacer strip is used to prevent the composite waterproof membrane layer from being excessively bent at the bend. At the same time, adhesive is applied only to the upper part of the joint. Under the condition of moderate soil settlement, the composite waterproof membrane layer has a certain degree of extensibility and the reserved fold position can be pulled open. After the external waterproof concrete layer and structural layer are cracked due to settlement, the composite waterproof membrane layer can still maintain the waterproof effect. Only crack repair is needed to continue to maintain the waterproof effect, which greatly increases the service life of the waterproof.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A seepage-resistant underground floor protection structure includes a structural layer, a composite waterproof membrane layer, and a waterproof concrete layer laid on rammed earth on the bottom surface of the basement. The composite waterproof membrane layer is composed of asphalt material laid on copper foil. The joints of the adjacent composite waterproof membrane layers extend beyond the copper foil surface. The copper foil surfaces in contact with the extended portions are bonded together with adhesive to form a double-layer structure and then pressed to one side. A pad is placed at the bend on the side of the pressing direction. Adhesive is used to accumulate and seal the ends of the double-layer structure.

[0007] Furthermore, the pad is formed using an elastic rubber strip.

[0008] Furthermore, the elastic rubber strip has a drum-shaped cross-section and is arranged with the flat side facing upwards.

[0009] Furthermore, a pad is placed in the space formed by bending the composite waterproof roll, and the adhesive does not extend into this space.

[0010] Furthermore, the length of the portion extending beyond the joint of the adjacent composite waterproof membrane layers is 5cm-10cm.

[0011] Furthermore, when the ends of the double-layer structure are sealed with adhesive, the accumulated adhesive is trimmed into a bevel.

[0012] Furthermore, the waterproof concrete layer is formed directly on the composite waterproof membrane layer after the composite waterproof membrane layer is laid, and its thickness is more than 4cm.

[0013] Furthermore, the waterproof concrete layer is made of rare earth silicate cement.

[0014] Furthermore, the copper foil surface extending beyond the interface of the composite waterproof membrane layer is only coated with adhesive on the top.

[0015] Furthermore, the waterproof concrete layer also has a self-leveling paint layer.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0017] 1. A seepage-resistant underground floor protection structure, comprising a composite waterproof membrane layer of asphalt material laid on copper foil, and a special joint structure between adjacent composite waterproof membrane layers, using spacers to prevent excessive bending of the composite waterproof membrane layer at the bends, and applying adhesive only to the upper part of the joint, so that the composite waterproof membrane layer can be stretched open under normal soil settlement conditions due to its inherent ductility and the reserved fold position. Even after the external waterproof concrete layer and structural layer are cracked due to settlement, the composite waterproof membrane layer can still maintain its waterproof effect, and only crack repair is needed to continue maintaining the waterproof effect, greatly increasing the service life of the waterproof layer.

[0025] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0026] Example:

[0027] like Figure 1 Figure 2As shown, a preferred embodiment of this utility model provides a seepage-resistant underground floor protection structure, which includes a structural layer 2, a composite waterproof membrane layer 3, and a waterproof concrete layer 4 laid on rammed earth 1 on the bottom surface of the basement, arranged from bottom to top. The composite waterproof membrane layer 3 is composed of asphalt material 302 laid on copper foil 301. The joints of adjacent composite waterproof membrane layers 3 extend beyond the surface. The copper foil 301 surfaces in contact with the extended portions are bonded together with adhesive 5 to form a double-layer structure, which is then pressed to one side. A pad 6 is placed at the bend on the pressing side. The ends of the double-layer structure are sealed with adhesive 5. A dedicated joint structure is set between adjacent composite waterproof membrane layers 3. Spacers 6 prevent excessive bending at the bends of the composite waterproof membrane layers 3, providing them with a certain degree of tensile strength. Adhesive 5 is applied only to the upper part of the joint, allowing the composite waterproof membrane layers 3 to maintain their elasticity and allow for the opening of the folded portion even under moderate settlement of the rammed earth 1. Even after the external waterproof concrete layer 4 and structural layer 2 are cracked due to settlement, the composite waterproof membrane layer 3 can still maintain its waterproof effect; only crack repair is needed to continue the waterproofing, greatly extending the lifespan of the waterproofing. Structural layer 2 is the basic basement structure constructed with cement and is in direct contact with the outside. The waterproofing structure is then built on top of structural layer 2. The composite waterproof membrane layer 3 consists of asphalt material 302 laid on copper foil 301. It can be coated with asphalt material on one or both sides, depending on the requirements. When using single-sided asphalt material, additional anti-corrosion treatment of the copper foil is required, which will not be elaborated here.

[0028] Furthermore, the pad 6 is formed using an elastic rubber strip. The use of an elastic rubber strip can achieve buffering capacity. When impacted during construction, it can also buffer and recover the impacted area, ensuring that it will not be completely compressed and tightly adhered. At the same time, the upper part is waterproofed and compressed using adhesive 5, which can achieve the requirement of complete sealing and waterproofing. If necessary, the allowance and size of the pad 6 can be increased to increase the range that can be pulled.

[0029] Furthermore, the elastic rubber strip adopts a drum cross-section with the flat side facing upwards, which can ensure good contact without forming local pressure and make pulling relatively smooth. If necessary, the surface friction of the elastic rubber strip can be smoothed to avoid excessive friction. Of course, using an elastic rubber strip is a more suitable structure for the pad, but other structures, such as round or square strips, can also be used if necessary.

[0030] Furthermore, a pad 6 is placed in the space formed by the bending of the composite waterproof roll. The adhesive does not extend into this space. It serves as a redundant length for the composite waterproof roll when it is pulled, and it is usually in a flat state, so it will not affect the flatness of the surface. It should be noted that the scale on the drawing has been enlarged for easier viewing and is used as a structural reference.

[0031] Furthermore, the length of the portion extending beyond the joint of the adjacent composite waterproof membrane layer 3 is 5cm-10cm, and the actual length is set according to the probability and degree of settlement of the rammed earth 1.

[0032] Furthermore, when the ends of the double-layer structure are sealed with adhesive 5, the accumulated adhesive 5 is trimmed into a slope. Setting it as a slope can reduce the amount of material used and ensure the surface is flat, which is convenient for affecting the overall structure and facilitates construction.

[0033] Furthermore, the waterproof concrete layer 4 is formed directly on the composite waterproof membrane layer 3 after the composite waterproof membrane layer 3 is laid, and its thickness is more than 4cm. Of course, the waterproof concrete layer 4 only needs to meet the usage requirements at its thinnest point and will not easily crack under pressure.

[0034] Furthermore, the waterproof concrete layer 4 is made of rare earth silicate cement, which is dense and has high hardness, providing good protection and seepage prevention, thus further supplementing the waterproofing. A self-leveling paint layer 7 is also applied to the waterproof concrete layer 4, serving as a self-leveling floor coating for leveling.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions and improvements made by those skilled in the art within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
