Description

Technical Field

[0001] The present application belongs to the technical field of basement construction, and specifically relates to a basement waterproofing construction structure. Background Art

[0002] In the waterproofing construction of the basement, it is usually required to overlap the waterproof layers between two adjacent foundation pits to form a continuous and complete waterproof layer. However, due to the limitations of the on-site construction environment, it is difficult to achieve synchronous construction of two adjacent foundation pits. In order to ensure that the waterproof layer constructed first can smoothly form an effective overlap with the waterproof layer constructed later, the most common practice at this stage is to reserve a stubble portion for the waterproof layer of the first foundation pit and use plastic film or wooden pads to temporarily protect the stubble portion. After the second foundation pit to be constructed later is paved, the plastic film or wooden pads are removed, and the waterproof layer of the second foundation pit is overlapped on the stubble portion of the waterproof layer of the first foundation pit. However, judging from the current construction results, under the temporary protection of the plastic film or wooden pads, the stubble portion of the waterproof layer will still often be damaged. The reason is that the on-site construction environment is too complicated, especially at the junction of the two foundation pits, with many processes and a large amount of personnel movement, which can easily cause the plastic film or wooden pads pressed against the stubble portion to shift and be damaged, making it impossible to effectively protect the stubble portion. Utility Model Content

[0003] In response to at least one of the above-mentioned defects or shortcomings of the prior art, the present application provides a basement waterproof construction structure that can effectively protect the stubble part of the waterproof layer during construction and is conducive to increasing the walking space for construction workers.

[0004] In order to achieve the above objectives, the present application provides a basement waterproof construction structure, comprising:

[0005] Ground-connected walls;

[0006] A first foundation pit is provided on one side of the ground-connected wall;

[0007] a first bottom plate, arranged to cover the bottom surface of the first foundation pit and connected to the side wall surface of the ground connection wall;

[0008] a bottom plate receiving groove formed at a top edge portion where the first bottom plate meets a side wall surface of the ground connection wall; and

[0009] a first waterproof layer, provided between the first bottom plate and the bottom surface of the first foundation pit and between the first bottom plate and the side wall surface of the ground connection wall;

[0010] Part of the first waterproof layer located between the first bottom plate and the side wall of the ground-connected wall is arranged beyond the top surface of the first bottom plate, and the part of the first waterproof layer exceeding the top surface of the first bottom plate is received in the bottom plate receiving groove.

[0011] In some embodiments, the basement waterproofing construction structure includes a bottom plate protection structure that is detachably filled in the bottom plate storage groove. When the bottom plate protection structure is filled in the bottom plate storage groove, the top surface of the bottom plate protection structure is flush with the top surface of the first bottom plate.

[0012] In some embodiments, the bottom plate protection structure includes a counterweight block and a waterproof film layered in sequence.

[0013] In some embodiments, a stepped bottom plate overlap portion is formed at a portion where the first bottom plate borders the side wall of the ground connection wall, and the bottom plate receiving groove is formed in a top edge portion of the bottom plate overlap portion. The basement waterproofing construction structure further includes a second foundation pit and a second bottom plate. The second foundation pit is arranged on the other side of the ground connection wall, and the second bottom plate covers the second foundation pit bottom surface of the second foundation pit and spans the ground connection wall and overlaps the bottom plate overlap portion. The portion of the second bottom plate overlapping the bottom plate overlaps the bottom plate receiving groove.

[0014] In some embodiments, the basement waterproof construction structure further includes a second waterproof layer disposed between the second bottom plate and the bottom surface of the second foundation pit.

[0015] In some embodiments, the second waterproof layer extends out of the bottom surface of the second foundation pit and covers the top surface of the ground-connected wall. The portion of the second waterproof layer covering the top surface of the ground-connected wall exceeds the top surface of the ground-connected wall. The portion of the second waterproof layer exceeding the top surface of the ground-connected wall is received in the bottom plate receiving groove.

[0016] In some embodiments, a portion of the second waterproof layer received in the bottom plate receiving groove and a portion of the first waterproof layer received in the bottom plate receiving groove are bonded to each other.

[0017] In some embodiments, the basement waterproof construction structure further includes a waterproof penetration component, which penetrates and fixes the portion of the second waterproof layer received in the bottom plate storage groove and the portion of the first waterproof layer received in the bottom plate storage groove.

[0018] In some embodiments, the basement waterproof construction structure further includes a sealing filler layer for filling in the bottom plate receiving groove to seal the bottom plate receiving groove, and the sealing filler layer is arranged flush with the top surface of the bottom plate overlapping portion.

[0019] In some embodiments, the top surface of the second bottom plate and the top surface of the first bottom plate are flush with each other.

[0020] Through the above technical solution, the basement waterproof construction structure of the present application can store the portion of the first waterproof layer that exceeds the top surface of the first bottom plate in the bottom plate storage groove. In other words, the stubble part of the first waterproof layer can be stored in the bottom plate storage groove, so that the stubble part of the first waterproof layer will not be directly exposed to the top surface of the first bottom plate, thereby achieving effective protection of the stubble part and widening the walking space of the first bottom plate to prevent construction workers from stepping on the stubble part.

[0021] Other features and advantages of the embodiments of the present application will be described in detail in the subsequent detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following describes the specific embodiments of the present application in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present application and are not intended to limit the present application.

[0036] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with exemplary embodiments.

[0037] like Figures 1 to 3 As shown, an exemplary embodiment of the present application provides a basement waterproof construction structure, which mainly includes a ground-connected wall 1, a first foundation pit 2, a first bottom plate 3, a bottom plate receiving groove 4, and a first waterproof layer 5. Among them, the first foundation pit 2 is arranged on one side of the ground-connected wall 1, the first bottom plate 3 is arranged to cover the first foundation pit bottom surface 201 of the first foundation pit 2, the side surface of the first bottom plate 3 is connected to the side wall surface of the ground-connected wall 1, the bottom plate receiving groove 4 is formed at the top edge of the first bottom plate 3 and the side wall surface of the ground-connected wall 1, the first waterproof layer 5 is arranged between the first bottom plate 3 and the first foundation pit bottom surface 201 and between the first bottom plate 3 and the side wall surface of the ground-connected wall 1, the portion of the first waterproof layer 5 located between the first bottom plate 3 and the side wall surface of the ground-connected wall 1 exceeds the top surface of the first bottom plate 3, and the portion exceeding the top surface of the first bottom plate 3 is received in the bottom plate receiving groove 4, which is equivalent to reserving a stubble portion of the first waterproof layer 5 and receiving the stubble portion in the bottom plate receiving groove 4.

[0038] In the basement waterproofing construction structure of this exemplary embodiment, the ground-connected wall 1 serves as a partition between the first foundation pit 2 and the second foundation pit 7. The first waterproof layer 5 and the first floor slab 3 are sequentially laid in the first foundation pit 2. The first waterproof layer 5 extends from the bottom surface of the first floor slab 3 to the interface between the first floor slab 3 and the ground-connected wall 1, effectively preventing water from leaking from the first foundation pit bottom 201 to the first floor slab 3. The first floor slab 3 is typically cast from concrete, and after casting, it allows construction workers to walk on it while performing other steps. Therefore, in order to better place the part of the first waterproof layer 5 that exceeds the top surface of the first base plate 3 (i.e., the stubble part), the first waterproof layer 5 of this part is stored in the base plate storage groove 4, so that the first waterproof layer 5 of this part will not be directly exposed on the top surface of the first base plate 3, thereby achieving effective protection of the stubble part of the first waterproof layer 5, and will not hinder the walking and activities of the construction workers, widening the walking space of the first base plate 3, and effectively preventing the construction workers from stepping on the stubble part of the first waterproof layer 5, avoiding damage to the first waterproof layer 5 and affecting the subsequent overlapping effect.

[0039] It should be noted that the bottom plate receiving groove 4 can be formed integrally with the first bottom plate 3 when the first bottom plate 3 is cast, or the bottom plate receiving groove 4 can be excavated after the first bottom plate 3 is cast, and this application does not limit this. In addition, the notch of the bottom plate receiving groove 4 can be as follows Figure 1It is set upward as shown in the embodiment, and can also be set toward one side of the ground-connected wall 1, that is, the right side in the figure. In this way, after the stubble part of the first waterproof layer 5 is stored, the stubble part of the first waterproof layer 5 can be better shielded, which is beneficial to improving its protection effect. This application does not limit this.

[0040] In an optional or preferred embodiment, Figure 1 As shown, the basement waterproofing construction structure includes a bottom plate protective structure 6 that is detachably filled in the bottom plate receiving groove 4. Thus, when the portion of the first waterproof layer 5 that extends beyond the top surface of the first bottom plate 3 is received in the bottom plate receiving groove 4, the bottom plate receiving groove 4 can be temporarily sealed by filling the bottom plate protective structure 6 in the bottom plate receiving groove 4, thereby achieving the purpose of better protecting the first waterproof layer 5. When the waterproof layer needs to be overlapped later, the bottom plate protective structure 6 can be removed again without affecting the subsequent overlapping process. In addition, when the bottom plate protective structure 6 is filled in the bottom plate receiving groove 4, the top surface of the bottom plate protective structure 6 is flush with the top surface of the first bottom plate 3, so that the top surface of the first bottom plate 3 and the top surface of the bottom plate protective structure 6 form a flat, non-protruding surface, which will not affect the walking of construction workers, and can effectively avoid damage to the bottom plate protective structure 6 during the construction process, further improving the protection effect of the first waterproof layer 5.

[0041] In an optional or preferred embodiment, the floor protection structure 6 includes a counterweight and a waterproof film sequentially layered one above the other. The waterproof film is laid over the first waterproof layer 5 housed in the floor storage slot 4 to prevent rainwater and dust from eroding the first waterproof layer 5. The counterweight compresses the waterproof film and the first waterproof layer 5 to further protect them from impacts from hard objects or wind. In this embodiment, a plastic film can be used as the waterproof film, and stones or blocks can be used as the counterweights, although this application does not limit this.

[0042] In an optional or preferred embodiment, Figure 1 The basement waterproofing construction structure is shown on the basis of Figure 2 As shown, the basement waterproofing construction structure also includes a second foundation pit 7 and a second bottom plate 8, wherein the second foundation pit 7 is arranged on the other side of the ground-connected wall 1, and the part of the first bottom plate 3 bordering the side wall surface of the ground-connected wall 1 is formed with a stepped bottom plate overlapping portion 301, and the above-mentioned bottom plate receiving groove 4 is formed in the top edge portion of the bottom plate overlapping portion 301, and the second bottom plate 8 is arranged to cover the second foundation pit bottom surface 701 of the second foundation pit 7, and span the ground-connected wall 1 to overlap on the bottom plate overlapping portion 301, so that the first bottom plate 3 and the second bottom plate 8 are cast as an integrated bottom plate. At this time, the part of the second bottom plate 8 overlapping on the bottom plate overlapping portion 301 covers the bottom plate receiving groove 4, thereby effectively preventing water from leaking into the basement from the construction joint between the first bottom plate 3 and the ground-connected wall 1.

[0043] exist Figure 2 In the basement waterproof construction structure shown in FIG, the first foundation pit 2 and the second foundation pit 7 can be regarded as being combined into a larger foundation pit. It should be noted that, during the construction of the basement, when the first foundation pit 2 is constructed first, Figure 1 As shown, it is necessary to temporarily retain the ground wall 1 on the ground, and after the construction of the first foundation pit 2 is completed, the ground wall 1 is formed. Figure 1 After the basement waterproofing structure is constructed, the ground-connected wall 1 can be removed to facilitate merging the first foundation pit 2 and the second foundation pit 7 into one. When pouring the second bottom plate 8, the second bottom plate 8 is overlapped on the first bottom plate 3 to form a basement as shown in FIG. Figure 2 The basement waterproof construction structure shown. It can be understood that in the actual construction process, it is precisely because of the existence of some special projects or terrain structures, such as the ground-connected wall 1 mentioned in this article, that there is a time difference in the construction of the two foundation pits, and it is impossible to carry out continuous construction in the normal construction sequence. Therefore, it is necessary to reserve the stubble part of the first waterproof layer 5 during the construction of the first foundation pit, and adopt the above-mentioned temporary protection method of closing to the bottom plate receiving groove 4. The structure between the first foundation pit 2 and the second foundation pit 7 in this embodiment may not be limited to a ground-connected wall, but may also be other structural forms such as a mixing pile, and this application does not limit this.

[0044] When the second base plate 8 is overlapped on the base plate overlap portion 301, the top surface of the second base plate 8 is flush with the top surface of the first base plate 3, so that the entire base plate plane formed by the second base plate 8 and the first base plate 3 is flat and has no protrusions, which does not affect the passage of on-site construction.

[0045] In an optional or preferred embodiment, Figure 2 As shown, the basement waterproof construction structure further includes a second waterproof layer 9 arranged between the second bottom plate 8 and the second foundation pit bottom surface 701, thereby preventing rainwater from penetrating into the basement from the second foundation pit bottom surface 701.

[0046] Furthermore, the second waterproof layer 9 extends out of the second foundation pit bottom surface 701 and covers the top surface of the ground connection wall 1 (at this time, the part of the ground connection wall 1 located on the ground has been removed). The part of the second waterproof layer 9 covering the top surface of the ground connection wall 1 exceeds the top surface of the ground connection wall 1, that is, the joint part of the second waterproof layer 9 is reserved, and the part of the second waterproof layer 9 exceeding the top surface of the ground connection wall 1 is received in the bottom plate receiving groove 4, thereby effectively protecting the joint part of the second waterproof layer 9, and the second waterproof layer 9 can be pressed against the groove wall of the bottom plate receiving groove 4, thereby enhancing the water-stopping effect.

[0047] Furthermore, the portion of the second waterproof layer 9 received in the bottom plate receiving groove 4 and the portion of the first waterproof layer 5 received in the bottom plate receiving groove 4 are bonded to each other, so that the first waterproof layer 5 and the second waterproof layer 9 form a continuous and complete waterproof layer, thereby improving the overall waterproof effect of the basement waterproof construction structure.

[0048] In an optional or preferred embodiment, the basement waterproof construction structure further includes a waterproof penetration component 10, which penetrates and fixes the portion of the second waterproof layer 9 received in the bottom plate receiving groove 4 and the portion of the first waterproof layer 5 received in the bottom plate receiving groove 4, thereby strengthening the connection strength between the first waterproof layer 5 and the second waterproof layer 9. In this embodiment, if Figure 3 As shown, the waterproof connection assembly 10 may include a U-shaped strip for compressing the first waterproof layer 5 and the second waterproof layer 9, and a screw that simultaneously connects the U-shaped strip, the first waterproof layer 5 and the second waterproof layer 9, wherein the tail of the screw can simultaneously connect the first base plate 3.

[0049] The present application can select one of bonding or waterproof penetration component 10 penetration as the connection method between the first waterproof layer 5 and the second waterproof layer 9, but in order to achieve a better connection effect, in this embodiment, after the first waterproof layer 5 and the second waterproof layer 9 are bonded to each other by adhesive, the waterproof penetration component 10 can be used to penetrate and fix the second waterproof layer 9 and the first waterproof layer 5 at the same time.

[0050] Furthermore, the basement waterproof construction structure of the present application also includes a sealing filler layer 11 for filling in the bottom plate receiving groove 4 to seal the bottom plate receiving groove 4. Specifically, a sealing paste can be used as the sealing filler layer 11. When the first waterproof layer 5 and the second waterproof layer 9 are both received in the bottom plate receiving groove, by filling the sealing filler layer 11 in the bottom plate receiving groove 4, the first waterproof layer 5 and the second waterproof layer 9 can be covered, thereby further improving the protection effect of the waterproof layer and effectively avoiding leakage in the bottom plate receiving groove 4. In addition, when the sealing filler layer 11 is filled in the bottom plate receiving groove 4, the sealing filler layer 11 and the top surface of the bottom plate overlapping portion 301 are flush with each other, thereby ensuring that the top surface of the bottom plate overlapping portion 301 is flat and has no protrusions, so that the second bottom plate 8 can be flatly overlapped on the first bottom plate 3.

[0051] In a specific embodiment, the construction process of the basement waterproof construction structure of the present application is as follows:

[0052] 1. Lay the first waterproof layer 5 on the first foundation pit bottom surface 201 of the first foundation pit 2, turn the first waterproof layer 5 up to the side wall surface of the ground-connected wall 1, and temporarily fix the turned-up part of the first waterproof layer 5 with nails;

[0053] 2. Cast the first bottom plate 3 on the first waterproof layer 5 so that the first bottom plate 3 covers the entire first foundation pit bottom surface 201, and cast and form the bottom plate receiving groove 4 and the bottom plate overlapping portion 301 on the first bottom plate 3;

[0054] 3. Unfasten the portion of the first waterproof layer 5 that has been turned up to the side wall of the ground-connected wall 1 and store it in the bottom plate storage groove 4. Then, temporarily seal the bottom plate storage groove 4 with a plastic film and a counterweight.

[0055] 4. Remove the ground portion of the ground-connected wall 1, lay a second waterproof layer 9 on the second foundation pit bottom surface 701 of the second foundation pit 7, and extend the second waterproof layer 9 into the bottom plate receiving groove 4 for closing;

[0056] 5. Use glue to bond the second waterproof layer 9 and the first waterproof layer 5 in the bottom plate storage groove 4 together, and use U-shaped strips to nail them in place. Then use sealing paste to fill the bottom plate storage groove 4 to seal it.

[0057] 6. Finally, cast the second base plate 8 on the second waterproof layer 9. The second base plate 8 is overlapped on the base plate overlap portion 301, and the second base plate 8 and the first base plate 3 are connected by the water stop plate 12, so that the first base plate 3 and the second base plate 8 form a flat large base plate, thereby completing the construction of the basement waterproof construction structure.
