Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a moisture-proof and erosion-resistant foundation wall for building construction and its construction method. Background Technology

[0002] Foundation walls are constructed below ground level, serving to transfer loads between the building and its foundation. Generally, foundation walls refer to the walls above the foundation but below the interior floor level. They act as a transition and connection between the building's walls and the foundation. Together with the foundation and basement roof, they form the basement spatial structure, effectively functioning as the foundation for the building's above-ground portion. They are typically constructed using rubble masonry, brick, or plain concrete.

[0003] Waterproofing is a crucial component of building construction, designed to protect the structure and interior spaces of buildings from water damage. It plays a vital role in the overall construction process. Waterproofing involves various parts of a building, including the basement, walls, floors, roof, and more. Its function is to prevent rainwater and domestic / industrial water leakage and groundwater erosion within the building's design lifespan, ensuring the structure and interior spaces remain undamaged and providing a comfortable and safe living environment.

[0004] Waterproofing is crucial for foundation walls because a large part, or even all of them, is buried in the soil of the foundation pit. Soil moisture will naturally seep out, and after penetrating the bottom of the foundation wall, the moisture will extend upwards along the wall and eventually spread to other walls, causing mold growth, weakening of the wall strength, and in severe cases, building collapse.

[0005] In addition, regarding corrosion resistance, the foundation wall is susceptible to moisture penetration, and the moisture in the soil often carries a large amount of acid and alkali components. These acid and alkali components will further accelerate the erosion of the wall as the moisture rises. Since the foundation wall is an important part of the building, its strength determines the service life and safety factor of the building. Therefore, in response to the defects of the foundation wall, those skilled in the art have proposed a moisture-proof and corrosion-resistant foundation wall structure for building construction, as well as the construction process of such a foundation wall structure. Summary of the Invention

[0006] To address the aforementioned deficiencies, the technical problem to be solved by the present invention is to provide a moisture-proof and corrosion-resistant foundation wall for a building, comprising: a strip foundation and a moisture-proof layer buried in the soil, and an anti-corrosion layer fixed on top of the moisture-proof layer;

[0007] The strip foundation includes a pad layer, a base layer stacked and fixed on the top surface of the pad layer, and a brick wall fixed on the top surface of the base layer.

[0008] The moisture-proof layer includes a U-shaped concrete strip, a notch opened inside the U-shaped concrete strip, and EPE foam partitions inserted on both sides inside the U-shaped concrete strip, and three cavities are opened at equal intervals inside the EPE foam partitions.

[0009] The anti-corrosion layer includes a concrete base, a water glass concrete layer fixed to the top surface of the concrete base, and a recycled rubber strip inserted into the cavity of the water glass concrete layer.

[0010] In the above-mentioned technical solution of a moisture-proof and corrosion-resistant building foundation wall and its construction method, preferably, the notch inside the U-shaped concrete strip is engaged with the top surface of the brick wall, and the inner cavity sidewall of the notch is fixed to the outer surface of the brick wall by concrete mortar.

[0011] In the above-mentioned technical solution of a moisture-proof and corrosion-resistant building foundation wall and its construction method, preferably, two chambers for inserting EPE foam partitions are opened inside the U-shaped concrete strip, and the chambers are symmetrically distributed on the left and right with the central axis of the U-shaped concrete strip as the base point.

[0012] In the above-mentioned technical solution of a moisture-proof and corrosion-resistant building foundation wall and its construction method, preferably, the bottom surface of the concrete base is fixedly connected to the top surface of the U-shaped concrete strip.

[0013] In the above-mentioned technical solution of a moisture-proof and corrosion-resistant building foundation wall and its construction method, preferably, the interior of the concrete base is provided with a placement port that is compatible with the recycled rubber strip, and the interior of the water glass concrete layer is provided with a slot that is compatible with the recycled rubber strip.

[0014] A method for constructing moisture-proof and corrosion-resistant foundation walls for building structures, comprising the following construction steps:

[0015] S1: After the foundation trench is excavated, cleaned and inspected and approved, the surface loose soil and disturbed soil are removed immediately, leaving no water accumulation. The foundation concrete is then constructed immediately, followed by the reinforcement of the strip foundation. Plywood formwork is used, and pine timber is used for support. After the entire formwork is installed, it is straightened by a string line and the two sides are firmly against the soil wall of the foundation trench. Then the strip foundation concrete is poured and the brick foundation is built.

[0016] S2: After the brick base is completed, the U-shaped concrete strip is inserted into the top of the brick wall. After insertion, the gap between the U-shaped concrete strip and the brick wall is filled with concrete mortar to fix the U-shaped concrete strip and the brick wall. After the U-shaped concrete strip and the brick wall are fixed, EPE foam partition is filled into the interior of the U-shaped concrete strip. The waterproof properties of EPE foam partition are used to prevent moisture in the soil from flowing upward.

[0017] S3: After the waterproof layer is laid and installed, the concrete base is connected to the top of the U-shaped concrete strip through concrete mortar. After the concrete mortar dries and cures, the water glass concrete layer is spliced ​​with the concrete base. After inserting the recycled rubber strip, concrete is poured into the gap between the recycled rubber strip, the water glass concrete layer and the concrete base. After it is fully cured, the blue-gray stone slabs are piled on the outside of the water glass concrete layer.

[0018] In the above-mentioned technical solution for the construction method of the foundation wall of a moisture-proof and corrosion-resistant building, preferably, the brick foundation in S1 is as follows: the bricks should be corrosion-resistant blue bricks, the mortar should be MU7.5 cement mortar, and the mortar joint should be 10mm; the brick foundation should have a 120×120mm hole at 1m intervals for use as a formwork support for the upper ground beam.

[0019] As can be seen from the above technical solution, the present invention provides a moisture-proof and corrosion-resistant foundation wall for building construction and its construction method. Compared with the prior art, the present invention has the following beneficial effects:

[0020] In this invention, a moisture-proof layer is added to the strip foundation of a building. EPE industrial foam partitions are added to the concrete strips, forming a barrier layer inside the strips. This isolates the foundation wall buried in the soil from moisture, preventing moisture from rising and eroding the wall. Above the moisture-proof layer, an anti-corrosion layer is placed. The anti-corrosion properties of water glass concrete combined with the waterproof properties of recycled rubber strips further isolate the upper wall, preventing it from being corroded by acids and alkalis. Thus, together with the moisture-proof layer, the foundation wall is protected and strengthened, improving its corrosion resistance and waterproofing. Attached Figure Description

[0037] The system includes a strip foundation 1 buried in the soil and a moisture barrier 2, as well as an anti-corrosion layer 3 fixed on top of the moisture barrier 2. The strip foundation 1 includes a pad 11, a base layer 12 stacked and fixed on the top surface of the pad 11, and a brick wall 13 fixed on the top surface of the base layer 12.

[0039] Specific Implementation Example 2.

[0040] Construction of moisture-proof and corrosion-resistant building foundation wall structure:

[0041] Foundation trench excavation: After measuring, mark the area with lime. Use a backhoe excavator to excavate the soil. Leave a 300mm working surface on each side of the excavation area compared to the foundation size as the position for the side formwork. Manually assist in slope and bottom repair. Excavate gradually backward from one end along the longitudinal direction of the building. The excavated soil is immediately transported off the site.

[0042] After the foundation trench is excavated, cleaned, and inspected for compliance, the surface loose soil and disturbed soil should be removed immediately, leaving no standing water, and the foundation concrete should be constructed immediately. The foundation concrete must be vibrated to ensure compaction, and the thickness, width, and surface leveling should be controlled with a screed. A bamboo stake should be driven in every meter. Then, the foundation concrete should be constructed. Before binding, the spacing of the reinforcing bars should be marked with chalk. At corners, T-shaped and cross-shaped intersections, the reinforcing bars should be overlapped. The reinforcing bars along the width of the foundation should be placed at the bottom, and the longitudinal distribution bars should be placed at the top, with the hooks of the reinforcing bars facing upwards. After binding, 35mm spacers should be placed.

[0043] Subsequently, the strip foundation formwork is erected using plywood formwork and pine timber for support. After the entire formwork is installed, it should be straightened with a string line and the two sides should be firmly against the soil wall of the foundation trench. Next, the strip foundation concrete is poured, using a construction method that brings the two ends together towards the middle. An immersion vibrator is used for vertical vibration, and the insertion points should be evenly arranged and moved point by point. When pouring in layers, each layer should not exceed 1.5 times the length of the vibrator. When vibrating the upper layer, the vibrator should be inserted 3-5 cm into the lower layer to strengthen the contact between the two layers.

[0044] Then, the brick foundation should be laid. The bricks used for the foundation should be corrosion-resistant blue bricks, and the mortar should be MU7.5 cement mortar with a 10mm joint. A 120×120mm hole should be left at 1m intervals in the brick foundation for use as a formwork support for the upper ground beam.

[0045] After the brick base is stacked, the top of the U-shaped concrete strip 21 is fitted into the brick wall 13. After it is fitted, the gap between the U-shaped concrete strip 21 and the brick wall 13 is filled with concrete mortar to fix the U-shaped concrete strip 21 and the brick wall 13. After the U-shaped concrete strip 21 and the brick wall 13 are fixed, EPE foam partition 23 is filled into the interior of the U-shaped concrete strip 21. The waterproof properties of EPE foam partition 23 are used to prevent moisture in the soil from flowing upward.

[0046] After the waterproof layer is laid and installed, the concrete base 31 is connected to the top of the U-shaped concrete strip 21 through concrete mortar. After the concrete mortar dries and cures, the water glass concrete layer 32 is spliced ​​with the concrete base 31. After inserting the recycled rubber strip 34, concrete is poured into the gap between the recycled rubber strip 34, the water glass concrete layer 32 and the concrete base 31. After waiting for complete curing, blue-gray stone slabs are stacked on the outside of the water glass concrete layer 32. Specific Implementation Example 3

[0048] Based on the premise of foundation wall construction, the construction steps for treating the foundation pit are as follows:

[0049] After the foundation pit excavation is completed, waterproof membrane base treatment is carried out. A 50mm small arc is made at the inside corners and a 10mm small arc is made at the outside corners. Clean the base layer of debris, dust and slag. Use a long-handled roller to apply the special waterproof base treatment agent to the treated base surface of the large surface, inside and outside corners, post-pouring strips, sump pits, foundation pits and other details. The agent should be applied evenly.

[0050] Using the same material as the main surface, the cut corners are reinforced at two-sided and three-sided corners. The material is spread out evenly on both the flat and vertical surfaces. On the prepared and dried base surface, according to the width of the selected roll material, the overlap size (100mm on both the long and short sides) is left. The baseline for laying the roll material is marked so that the roll material can be laid according to this baseline.

[0051] Use a gasoline torch to heat the bottom surface of the roll material and the surface of the base layer, melting the asphalt on the bottom surface of the roll material. While heating, roll the roll material forward, then use a pressure roller to press it and squeeze out the air between the roll material and the base layer. After laying, the roll material should be flat and straight, with correct overlap dimensions, and the long and short sides should overlap by 100mm. The finished roll material should be free of wrinkles and twists. The overlap area should ensure that the effective overlap between the roll materials is ≥100mm. At the same time, use the torch to fully heat the bottom surface of the upper roll material and the upper surface of the lower roll material asphalt coating layer, ensuring that the asphalt between the roll materials at the overlap is densely fused and that molten asphalt oil oozes out.

[0052] After the first layer of roofing membrane passes inspection, mark the lines and lay out the layout. Then lay the second layer of roofing membrane, following the same procedure as the first layer. However, it is important to note that the upper and lower layers of roofing membrane must not be laid perpendicular to each other. They should be laid parallel to the first layer of roofing membrane, and the seams of the upper and lower layers of roofing membrane should be staggered by 1 / 3 to 1 / 2 of the width of the membrane. Other procedures are the same as for the first layer.
