Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a leak plugging structure for the basement floor Background Art
[0002] With the rapid development of the construction industry, the underground space is continuously exploited, and the problem of water leakage in underground projects is increasing day by day. When the groundwater leakage is serious, it not only affects the normal use of the basement, but also may cause the deformation or corrosion of the basement steel bars, seriously endangering the building safety
[0003] For the common leakage phenomenon of the basement floor, the existing leak plugging method is to use chemical grouting technology to plug the cracks. However, since it is difficult to accurately determine the leakage points on the floor, especially the relatively small leakage points, the effect of plugging leaks by using chemical grouting technology is not good. Therefore, it is necessary to provide a leak plugging structure for the basement floor, which can solve the problem that the chemical grouting technology in the prior art has a poor effect on plugging leaks on the floor Summary of the Invention
[0004] The purpose of the utility model is to provide a leak plugging structure for the basement floor, which can solve the problem that the chemical grouting technology in the prior art has a poor effect on plugging leaks on the floor
[0005] The utility model is realized as follows
[0006] A leak plugging structure for the basement floor includes a drainage groove, a hydrophobic component, post-poured concrete and a drainage structure; the drainage groove is formed in the leakage area of the basement floor, and one end of the drainage groove is communicated with the drainage structure of the basement; the hydrophobic component is arranged longitudinally in the drainage groove, and the post-poured concrete is poured in the drainage groove and covers the hydrophobic component, so that the water in the leakage area of the basement floor can flow into the drainage groove through the hydrophobic component
[0007] The hydrophobic component includes a hydrophobic plate and a geotextile. The hydrophobic plate is laid in the drainage groove, and the geotextile is laid on the hydrophobic plate; the post-poured concrete is poured on the hydrophobic plate
[0008] The hydrophobic component further includes a sand and gravel layer, and the sand and gravel layer covers between the two side edges of the geotextile and the two inner side walls of the drainage groove
[0009] The top surface of the post-poured concrete is flush with the top surface of the basement floor
[0010] The bottom surface of the hydrophobic plate fits the top surface of the bottom plate below the drainage groove
[0011] The top surface of the hydrophobic plate is an arc surface structure with a high middle and low sides
[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] 1. The utility model is provided with drainage grooves and drain components. The drainage grooves are opened in the leakage area of the basement floor, so that the leaking water can enter the drainage grooves and be discharged through the drain components. There is no need to accurately locate the leakage point. Based on the characteristic that water is better to be drained than to be blocked, the leaking water can be ensured to be discharged in a timely and effective manner, achieving the effect of plugging the leakage, and ensuring the safety of the basement and the entire building structure.
[0014] 2. The utility model is provided with post-fill concrete and drainage structure. The post-fill concrete is filled in the drainage ditch and forms a whole with the basement floor, which does not affect the structural beauty and normal use of the basement floor. At the same time, the drainage structure can use the existing drainage structure in the basement structure to discharge the leaked water. The structure is simple, the construction process is simplified, and the construction cost is low. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0019] Please see attached Figure 1 and attached Figure 2 A basement floor leak plugging structure includes a drainage ditch 1, a drain component, a post-fill concrete 2 and a drainage structure 3; the drainage ditch 1 is formed in the leakage area of the basement floor 4, and one end of the drainage ditch 1 is connected to the drainage structure 3 of the basement; the drain component is arranged in the drainage ditch 1 through the entire length, and the post-fill concrete 2 is poured in the drainage ditch 1 and covers the top of the drain component, so that the water in the leakage area of the basement floor 4 can flow into the drainage ditch 1 through the drain component.
[0020] When leakage occurs in the basement floor 4, the leakage area can be roughly determined without accurately locating the leakage point, and a drainage ditch 1 is excavated in the leakage area, and the drainage ditch 1 is connected to the drainage structure 3. Preferably, the drainage structure 3 can adopt a structure such as a water collection well or a floor drain that has been constructed in the basement structure, and there is no need to set up a separate drainage structure.
[0021] A hydrophobic component is laid in the drainage trench 1. After the water in the leakage area flows into the drainage trench 1, it is diverted to the drainage structure 3 through the hydrophobic component and discharged through the drainage structure 3, thus avoiding the influence of the seepage water on the use of the basement.
[0022] Please refer to the appendix Figure 2 The hydrophobic component includes a hydrophobic plate 5 and a geotextile 6. The hydrophobic plate 5 is laid in the drainage trench 1, and the geotextile 6 is laid on the hydrophobic plate 5; the post-cast concrete 2 is poured on the hydrophobic plate 5.
[0023] The specification of the hydrophobic plate 5 can be adaptively selected according to the actual drainage diversion requirements, and is used to divert the seepage water flowing into the drainage trench 1 to the drainage structure 3; the specification of the geotextile 6 can be adaptively selected according to the actual use requirements, and is used to prevent the seepage water from seeping out of the drainage trench 1.
[0024] Please refer to the appendix Figure 2 The hydrophobic component also includes a sand and gravel layer 7, and the sand and gravel layer 7 covers between the two side edges of the geotextile 6 and the two inner side walls of the drainage trench 1.
[0025] The grading and the amount of sand and gravel of the sand and gravel layer 7 can be adaptively adjusted according to the actual use requirements. Preferably, when the groundwater flows into the drainage trench 1, it can pass through the sand and gravel gaps of the sand and gravel layer 7 to ensure smooth drainage. At the same time, the sand and gravel layer 7 is laid along the two side edges of the geotextile 6 to ensure the effective laying of the geotextile 6 on the hydrophobic plate 5.
[0026] Please refer to the appendix Figure 2 The top surface of the post-cast concrete 2 is flush with the top surface of the basement floor 4.
[0027] After the post-cast concrete 2 fills the drainage trench 1, the post-cast concrete 2 is flush with the surface of the basement floor 4, ensuring the structural integrity and surface aesthetics of the basement floor 4.
[0028] Preferably, the bottom surface of the hydrophobic plate 5 can be attached to the top surface of the floor slab 8 below the drainage trench 1, ensuring the drainage effect of the seepage water in the drainage trench 1 through the hydrophobic plate 5 and preventing the groundwater from leaking into the floor slab 8.
[0029] Please refer to the appendix Figure 2 The top surface of the hydrophobic plate 5 is an arc surface structure that is high in the middle and low on both sides.
[0030] The water in the drainage trench 1 can be diverted to both sides through the hydrophobic plate 5 and then flow to the drainage structure 3 from both sides, preventing water accumulation in the drainage trench 1.
[0031] Please refer to the appendix Figure 1 and the appendix Figure 2 The construction process of the present utility model is as follows:
[0032] 1. Subgrade cleaning → 2. Measuring and setting out → 3. Cutting and chiseling of the basement floor 4 → 4. Installing the drainage board 5 → 5. Laying the geotextile 6 → 6. Pouring the post-patching concrete 2.
[0033] Specifically, subgrade cleaning includes: after the basement floor 4 is constructed on the floor slab 8, first remove the floating dust and garbage on the basement floor 4, secondly clean the leakage area of the basement floor 4 with an oil-water separator, then clean the ground around the leakage area with an air duct and dry it.
[0034] Measuring and setting out includes: according to the positions of drainage structures 3 such as sump wells or floor drains at the construction site, reasonably design the drainage line, and lay the control line of the drainage trench 1 on the basement floor 4 according to the designed drainage line.
[0035] Cutting and chiseling of the basement floor 4 includes: according to the determined construction plan, carry out cutting and chiseling operations on the basement floor 4 to ensure that the width and depth of the drainage trench 1 are sufficient to accommodate the drainage board 5, and properly handle the waste generated during the cutting and chiseling process.
[0036] Installing the drainage board 5 includes: after the cutting and chiseling are completed, put the drainage board 5 into the drainage trench 1 and ensure that the bottom surface of the drainage board 5 is in close contact with the top surface of the floor slab 8 without gaps to prevent water seepage. When installing the drainage board 5, protection measures need to be noted. When using the drainage board 5, the length and thickness of the board need to be noted to avoid affecting the leak-proof effect.
[0037] Laying the geotextile 6 includes: after the laying of the drainage board 5 is completed, a layer of geotextile 6 needs to be covered on the drainage board 5 to ensure that water does not seep out from the gap between the drainage board 5 and the geotextile 6. In addition, an appropriate amount of sand and gravel needs to be piled up at the edges of the geotextile 6 on both sides of the drainage trench 1 to form a sand and gravel layer 7 to ensure that the geotextile 6 covers the drainage board 5 tightly, so as to achieve a better waterproof effect.
[0038] Pouring the post-patching concrete 2 includes: after the geotextile 6 is laid, pour the post-patching concrete 2 to fill the drainage trench 1, and ensure that there is no height difference with the surface of the surrounding basement floor 4 after pouring.
[0039] The above is only the preferred embodiment of the present utility model and is not used to limit the protection scope of the present utility model. Therefore, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
