Description

Technical Field

[0001] The invention relates to the technical field of basement construction, in particular to a method for constructing an assembled waterproof protective layer. Background Art

[0002] In the use of the basement, a protective layer must be installed on the outer wall of the basement to ensure that the basement can be effectively waterproofed, so as to prevent the penetration of surface water or the rupture of pipes from having a great impact on the basement walls. After the protective layer is implemented on the outer wall of the basement, it can not only strengthen the waterproof function of the outer wall of the basement, but also greatly improve the safety performance of the basement and extend the service life of the basement. There are three main conventional waterproof protective layer methods:

[0003] The first is the brick wall protection method: clay bricks or non-clay bricks are generally used for masonry. When building, cement mortar is usually used to build brick walls. For example, if the thickness is 120mm, a deformation joint of about 20mm width is set at intervals of 6-8m, and masonry mortar needs to be filled to protect the waterproof layer and the wall. This method protects the waterproof material better and more efficiently, and can effectively prevent the damage of hard objects to the waterproof material during backfilling. Due to the rigidity of the brick wall, it can ensure the close combination between the backfill soil and the wall, making the basement exterior wall more firmly embedded, but this method requires a long construction period and high labor costs.

[0004] The second method is the soft layer protection method: usually polystyrene foam board (ordinary or extruded board) is used as the protection layer. Its advantages are lightness, easy installation, and no excessive pressure on the waterproof layer, but when backfilling, there is a greater risk of stones impacting and damaging the foam board.

[0005] The third method is the cement mortar protective layer method: directly apply cement mortar as a protective layer on the waterproof material. This method is suitable for low-height situations. When the height is high, it is difficult to apply mortar on the waterproof material, and its strength and durability are relatively poor.

[0006] In view of this, the inventor has invented a method for constructing an assembled waterproof protective layer to solve the above problems. Summary of the invention

[0007] In view of the above-mentioned technical problems existing in the prior art, a method for constructing an assembled waterproof protective layer is provided.

[0008] The purpose and effect of the present invention are achieved by the following specific technical means:

[0012] Installation steps of concrete auxiliary form plates: the first and second layers are horizontally laid with transverse plates, and the third layer is horizontally laid with longitudinal plates, and the upper and lower adjacent concrete auxiliary form plates need to be vertically staggered, and the elastic limit hooks on the concrete auxiliary form plates are inserted into the limit grooves of another concrete auxiliary form plate to connect the two adjacent concrete auxiliary form plates tightly together;

[0018] The limiting groove is a T-shaped groove. After the mounting block is inserted into the T-shaped groove, the two limiting hooks are pushed into the two ends of the T-shaped groove head respectively under the action of the elastic force of the limiting hooks.

[0019] During the installation of concrete auxiliary plates, the local staggered joints between the upper and lower adjacent concrete auxiliary plates shall not be less than 200mm.

[0020] During the installation of the concrete auxiliary plate, the gap between the two adjacent concrete auxiliary plates shall not be greater than 3mm, and the height between the plates shall not be greater than 3mm. The plate seams shall be filled with cement glue.

DETAILED DESCRIPTION

[0043] See also Figure 1-10, further illustrate the embodiments of the present invention;

[0044] A method for constructing an assembled waterproof protective layer comprises the following steps:

[0045] Concrete auxiliary board production steps: Figure 5-10 As shown, several concrete auxiliary form plates 3 are prefabricated. During processing, these concrete auxiliary form plates 3 are numbered according to the installation order so that the concrete auxiliary form plates 3 can be installed quickly and accurately in the later stage. The concrete auxiliary form plates 3 are recycled concrete plates. The concrete auxiliary form plates 3 include several transverse plates 31 and longitudinal plates 32. The transverse plates 31 and the longitudinal plates 32 have at least one side and at least one limiting groove 33, and at least one elastic limiting hook is installed; the elastic limiting hook includes a mounting block 34, a spring 1 36, a slide rail 1 37, a limiting hook 38 and a slide rail 2 39. The outer end of the mounting block 34 is provided with a notch 35, and the spring 1 36 is provided with a There are several and all are fixed in the slot 35, the slide rail 1 37 is fixed to the end of several springs 1 36, the slide rail 2 39 is parallel to the slide rail 1 37, and the side of the slide rail 2 39 close to the slide rail 1 37 is opened with a T-shaped slide groove, and two limit hooks 38 are provided and symmetrically distributed along the central axis of the mounting block 34, and the upper and lower ends of the limit hooks 38 slide into the upper and lower T-shaped slide grooves respectively through the slider, and the spring 2 381 is fixed between the two limit hooks 38. The setting of the elastic limit hook is conducive to the rapid splicing of the transverse plate 31 and the transverse plate 31, and the transverse plate 31 and the longitudinal plate 32 in the later stage, and can also enhance the overall strength of the concrete auxiliary plate 3;

[0046] Waterproof membrane layout steps: Figure 2-4As shown, a fertilizer trough 8 is arranged outside the basement, and the basement includes four side walls 1 and a top plate 5 cast on the top of the four side walls 1. The outer walls of the side walls 1 and the top plate 5 are coated with 1.5mm polymer cement waterproof coating to preliminarily strengthen the waterproof performance of the outer wall of the basement. The side walls 1 and the top plate 5 are fixed with waterproof membrane 2. The setting of the waterproof membrane 2 further strengthens the waterproof performance of the basement. A reinforcement layer 6 for pressing the waterproof membrane 2 is fixed on the top of the top plate 5. The reinforcement layer 6 includes a 20mm thick WSM15 cement mortar isolation layer cast on the waterproof membrane 2 and a 70mm thick C20 fine stone concrete rigid layer cast above the 20mm thick WSM15 cement mortar isolation layer. The reinforcement layer 6 is set to strengthen the connection strength of the waterproof membrane 2 fixed on the top of the top plate 5; the waterproof membrane 2 includes a butyl self-adhesive TPO root-penetration-resistant polymer waterproof membrane 21 and a self-adhesive polymer SBS elastomer modified asphalt Green waterproofing membrane 22, butyl self-adhesive TPO root-penetration-resistant polymer waterproofing membrane 21 is bonded to the outer wall of the side wall 1 and the top plate 5. The butyl self-adhesive TPO root-penetration-resistant polymer waterproofing membrane 21 adopts special polymer materials, which can effectively resist the puncture of plant roots and maintain the integrity of the waterproof layer. It has high tensile strength and tear strength, can effectively resist the generation and development of base cracks, enhance the waterproof effect of the building, and has good elasticity and elongation. It can adapt to the expansion and contraction deformation of the building caused by temperature and humidity changes, and effectively prevent the cracking and leakage of the waterproof protective layer. The self-adhesive polymer SBS elastomer modified asphalt waterproofing membrane 22 is bonded to the outside of the butyl self-adhesive TPO root-penetration-resistant polymer waterproofing membrane 21 and is located at the junction of the side wall 1 and the top plate 5, that is, the waterproof structure of the waterproof joint part of the side wall 1 and the top plate 5, ensuring the integrity and continuity of the waterproof protective layer and reducing the risk of leakage;

[0047] Base inspection and cleaning steps: clean the impurities remaining on the waterproof membrane 2, and check whether the waterproof membrane 2 is installed up to standard, for example: check whether the waterproof membrane 2 has hollows, damage, cracks, etc.; ensure that the waterproof membrane 2 is intact and improve the waterproof performance of the basement;

[0048] Installation steps of concrete auxiliary board: Figure 5As shown, the concrete auxiliary shape plate 3 is arranged according to the vertical dimensions of the basement side wall 1. The first and second layers are horizontally laid with the transverse plate 31 to ensure continuous installation. The third layer is horizontally laid with the longitudinal plate 32. The upper and lower adjacent concrete auxiliary shape plates 3 need to be vertically staggered. The local staggered joints of the upper and lower adjacent concrete auxiliary shape plates 3 shall not be less than 200mm. The gap between the two adjacent concrete auxiliary shape plates 3 shall not be greater than 3mm. The gap between the upper and lower plates shall not be greater than 3mm. The plate seams are filled with cement glue. The above arrangement method is used for installation. The invention saves materials (concrete auxiliary shape plate 3); the elastic limiting hook on the concrete auxiliary shape plate 3 is inserted into the limiting groove 33 of another concrete auxiliary shape plate 3, and the limiting groove 33 is a T-shaped groove. After the mounting block 34 is inserted into the T-shaped groove, the two limiting hooks 38 are pushed into the two ends of the T-shaped groove head respectively under the elastic force of the limiting hook 38, so that the two adjacent concrete auxiliary shape plates 3 are closely connected together, which is conducive to the rapid and accurate splicing of the transverse plate 31 and the transverse plate 31, and the transverse plate 31 and the longitudinal plate 32, and strengthens the overall strength of the concrete auxiliary shape plate 3;

[0049] Backfilling step: When the concrete auxiliary form plate 3 is installed to a height of 2-3m, pour the backfill soil 4 into the fertilizer trough 8 and roll and compact the backfill soil 4. The compaction degree of the backfill soil 4 is 0.92-0.96, until the position below the joint of the top concrete auxiliary form plate 3 is reached, which is conducive to the concrete auxiliary form plate 3 being firmly bonded to the waterproof membrane 2;

[0050] Repeat the steps of installing the concrete auxiliary plate and backfilling the soil until the waterproof protective layer is completed.

[0051] It should be noted that the backfill soil 4 includes fluidized solidified soil and plain soil. When the height of the backfill soil 4 is less than or equal to 3m, fluidized solidified soil is used for backfilling; when the height of the backfill soil 4 is greater than 3m, plain soil is used for backfilling; and the backfill soil 4 above the top plate 5 is backfilled in layers. Considering the load-bearing capacity of the basement top plate 5, the plain soil backfill in the non-planting area is backfilled and compacted by a small excavator and a small roller, and the thickness of each backfill layer is controlled at 270-330mm; the backfill in the planting area is backfilled with a small excavator, and the thickness of each backfill layer is controlled between 570-630mm; both the non-planting area and the planting area are where the backfill soil 4 height is greater than 3m.

[0052] When the assembled waterproof protective layer construction method in this embodiment is used, in the concrete auxiliary plate manufacturing step, the concrete auxiliary plate 3 is a recycled concrete plate, which is more economical and environmentally friendly, and the transverse plate 31 and the longitudinal plate 32 can be numbered in advance according to the installation sequence, which can speed up the installation speed of the later concrete auxiliary plate 3. By setting the limiting grooves 33 and the elastic limiting hooks on the transverse plate 31 and the longitudinal plate 32, it is convenient for the later transverse plate 31 to be quickly spliced ​​with the transverse plate 31 and the transverse plate 31 to be quickly spliced ​​with the longitudinal plate 32, and the overall strength of the concrete auxiliary plate 3 can be enhanced.

[0053] In the waterproofing membrane arrangement step, a layer of 1.5 mm polymer cement waterproofing coating is first applied around and on the top of the basement outer wall to perform preliminary waterproofing operations on the basement outer wall; then, a butyl self-adhesive TPO root-penetration-resistant polymer waterproofing membrane 21 is pasted around and on the top of the basement outer wall to perform a second waterproofing operation; and then, a self-adhesive polymer SBS elastomer-modified asphalt waterproofing membrane 22 is added at the junction of the side wall 1 and the top plate 5 to ensure the integrity and continuity of the waterproofing protective layer and reduce the risk of leakage;

[0054] In the base inspection and cleaning step, remove the impurities remaining on the waterproof membrane 2 to prevent affecting the paving of the concrete auxiliary plate 3, and check whether the waterproof membrane 2 is installed up to standard, so that the waterproof effect of the waterproof membrane 2 can be best when it is used later;

[0055] In the installation steps of the concrete auxiliary shape plates, the first and second layers are horizontally paved with the transverse plates 31, and the third layer is horizontally paved with the longitudinal plates 32. This layout method can save materials and reduce construction costs; the concrete auxiliary shape plates 3 are elastically clamped in the limiting grooves 33 through elastic limiting hooks, so that the two adjacent concrete auxiliary shape plates 3 can be quickly and accurately spliced ​​together, and the concrete auxiliary shape plates 3 can be neatly bonded to the outside of the waterproof membrane 2. Even when the backfill height of the fertilizer tank 8 is high, there is no need to add structural columns. The process is simpler, the waterproof effect is better, and the construction period is shorter. At the same time, the overall strength of the concrete auxiliary shape plates 3 can be strengthened, thereby improving the strength and durability of the waterproof protective layer.

[0056] In addition, the installation steps of the concrete auxiliary form plate and the backfill soil backfilling steps are repeatedly constructed alternately, and the backfill soil 4 is backfilled in layers and compacted, which is conducive to the concrete auxiliary form plate 3 being firmly bonded to the outside of the waterproof membrane 2, further enhancing the strength and durability of the waterproof protective layer.

[0057] Compared with the prior art, the advantages of this application are:

[0058] 1. The concrete auxiliary plate 3 is a recycled concrete plate. The waste concrete is reused after being processed, which can reduce the stacking of construction waste, reduce environmental pollution, make full use of existing resources, and reduce costs;

[0059] 2. When installing the concrete auxiliary shape plate 3, the first and second layers are horizontally laid with the transverse plate 31, and the third layer is horizontally laid with the longitudinal plate 32, and the upper and lower adjacent concrete auxiliary shape plates 3 need to be vertically staggered. The above layout method can save materials for installation;

[0060] 3. The concrete auxiliary shape plates 3 are elastically clamped in the limiting grooves 33 through elastic limiting hooks, so that two adjacent concrete auxiliary shape plates 3 can be quickly and accurately spliced ​​together, and the concrete auxiliary shape plates 3 can be neatly bonded to the outside of the waterproof membrane 2. Even when the backfill height of the fertilizer tank 8 is high, there is no need to add structural columns, the process is simpler, the waterproof effect is good, the construction period is shorter, and the overall strength of the concrete auxiliary shape plates 3 can be strengthened, thereby improving the strength and durability of the waterproof protective layer;

[0061] 4. The concrete auxiliary plate 3 is bonded to the outside of the waterproof membrane 2. The concrete auxiliary plate 3 acts as a hard protective shell, which can effectively prevent the waterproof membrane 2 from being damaged when the backfill soil 4 is backfilled, and can greatly improve the waterproof performance of the basement;

[0062] 5. The installation of the concrete auxiliary form plate 3 and the backfilling of the backfill soil 4 are carried out alternately for many times, and the backfilling of the backfill soil 4 is carried out in layers and compacted and rolled, which is conducive to the concrete auxiliary form plate 3 being firmly bonded to the outside of the waterproof membrane 2;

[0063] 6. After the butyl self-adhesive TPO root-penetration-resistant polymer waterproofing membrane 21 is bonded around the outside and top of the basement, a self-adhesive polymer SBS elastomer-modified asphalt waterproofing membrane 22 is added at the junction of the side wall 1 and the top plate 5, which ensures the integrity and continuity of the waterproof protective layer and reduces the risk of leakage.

[0064] The real case is as follows:

[0065] (1) The construction site is located in the experimental building of the Huxi Science Center of Chongqing University, with a total construction area of ​​247,700 square meters. The basement has two floors with a construction area of ​​about 65,000 square meters. The size and shape of the horizontal plate 31 and the vertical plate 32 are almost the same, but the placement direction is different. Both are 1200*600*40 (unit: mm) concrete auxiliary plate 3. The original 100m thick MU10 sintered shale porous brick protection wall is replaced with a 40mm thick prefabricated concrete auxiliary plate 3, which is bonded with the waterproof membrane 2 with cement special glue adhesive. It can not only reduce the material consumption and reduce the dead weight of the building, but also the concrete auxiliary plate 3 can be prefabricated, the on-site speed is fast, the construction efficiency is improved, and it has strong strength and durability, can provide better structural support and seismic performance, and is more economical and environmentally friendly;

[0066] (2) First, apply a layer of 1.5 mm polymer cement waterproof coating on the outer wall of the basement to perform preliminary waterproofing operations on the outer wall of the basement; then, paste the butyl self-adhesive TPO root-penetration-resistant polymer waterproofing membrane 21 around and on the top of the outer wall of the basement to perform a second waterproofing operation; and then add a self-adhesive polymer SBS elastomer modified asphalt waterproofing membrane 22 at the junction of the side wall 1 and the top plate 5 to ensure the integrity and continuity of the waterproof protective layer and reduce the risk of leakage;

[0067] (3) Then clean the impurities remaining on the waterproof membrane 2 and check whether the waterproof membrane 2 has hollows, damage, cracks, etc.;

[0068] (4) The cement-specific glue adhesive should be evenly prepared during use;

[0069] (5) Arrange the concrete auxiliary form panels 3 according to the vertical dimensions of the basement side wall 1. The first and second layers are horizontally laid with transverse panels 31, and the third layer is horizontally laid with longitudinal panels 32. The upper and lower adjacent concrete auxiliary form panels 3 need to be vertically staggered, and the local staggered seam shall not be less than 200 mm.

[0070] The pasting of the concrete auxiliary plate 3 should be carried out from the detailed nodes (embedded sleeves) and the corners to the middle to make a horizontal control line to ensure horizontal pasting. The pasting in the section should be carried out from bottom to top;

[0071] When bonding the concrete auxiliary shape plate 3, first evenly apply the prepared cement adhesive to the bonding surface of the concrete auxiliary shape plate 3. When the two limit hooks 38 are in the initial state, since the spring 2 381 is in a naturally extended state, the hook portion of the limit hook 38 is located outside the mounting block 34, which is the same as the state of the hook portion of the limit hook 38 in the limit groove 33 (such as Figure 7 As shown in FIG. 1 , the construction worker needs to press the two limit hooks 38 toward the middle of the mounting block 34 by hand, and the spring 2 381 will be gradually compressed. When the spring 2 381 is compressed to the maximum extent, the hook portion of the limit hook 38 is flush with the outer side of the mounting block 34 or is located on the inner side of the mounting block 34 (as shown in FIG. 1 ). Fig. 9 As shown), align the second slide rail 39 on this concrete auxiliary form plate 3 with the corresponding limiting groove 33 on the other concrete auxiliary form plate 3, and make the second slide rail 39, limiting hook 38 and mounting block 34 enter the T-slot (limiting groove 33). Under the action of multiple springs 1 36, it is conducive to the second slide rail 39 to be stably fitted on the T-slot head, so that the second spring 381 can stably push the two limiting hooks 38 to enter the two ends of the T-slot head respectively during the process of releasing elastic potential energy, so that the two adjacent concrete auxiliary form plates 3 are firmly spliced ​​together, and then evenly knocked with a rubber hammer to make the waterproof membrane 2 fit closely with the concrete auxiliary form plate 3. It should be noted that the number and position of the limiting grooves 33 and elastic limiting hooks of the transverse plate 31 and the longitudinal plate 32 can be selected according to needs, as long as the two adjacent concrete auxiliary form plates 3 can be firmly installed together. During the construction process, the gap between the plates shall not be greater than 3mm, and the high layer between the plates shall not be greater than 3mm. The plate seams should be filled with cement glue;

[0072] (6) When the concrete auxiliary plate 3 is installed to a height of 2.4 m, backfill soil 4 is poured into the fertilizer trough 8 and compacted to the corresponding elevation, leaving a 20 cm joint for the concrete auxiliary plate 3. The compaction degree of the backfill soil 4 is 0.94, and then the second round of concrete auxiliary plate 3 installation and backfill soil 4 backfilling is continued, and this cycle is repeated until the construction of the waterproof protective layer is completed;

[0073] Among them, the backfill height of the fertilizer trough 8 is about 8m, and the backfill soil 4 includes fluidized solidified soil and plain soil. When the height of the backfill soil 4 is less than or equal to 3m, fluidized solidified soil is used for backfilling; when the height of the backfill soil 4 is greater than 3m, plain soil is used for backfilling; and for the backfill soil 4 above the top plate 5, layered backfilling is adopted. Both the non-planting area and the planting area are at the place where the backfill soil 4 height is greater than 3m. Considering the load-bearing capacity of the basement top plate 5, the plain soil backfill in the non-planting area is backfilled with a small excavator and a small roller for backfilling, compaction and rolling, and the thickness of each backfill layer is controlled at 300mm; the planting area backfill is backfilled with a small excavator, and the thickness of each backfill layer is controlled at 600mm (including settlement). If the backfill thickness exceeds 600mm, settlement compaction should be carried out.

[0074] By adopting the above construction method, the basement waterproofing effect is good, and the construction period is saved by about 10 days and the labor cost is saved by about 550,000 yuan.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
