[0002] During the construction of waterproof membranes for the exterior walls of basements, there are often tight deadlines and a rush to backfill. In traditional construction projects, the waterproof layer of the exterior wall is guaranteed by pasting extruded boards or using cement mortar surface layers as a protective layer. The use of extruded boards for protection is more convenient for construction, but the extruded boards have problems such as thin material and loose joints, and are easy to fall off or damage during the backfilling process; while the use of cement mortar for protection has good surface hardness and the on-site mortar coverage of the waterproof membrane is also more comprehensive, but due to the narrow space between the underground exterior wall and the outer earthwork, the construction is difficult, the construction period is long, and the construction period is delayed. The poor construction quality makes the mortar protective layer easy to break and fall off in the later stage. The waterproof protective layer is unreliable, the waterproof membrane is easily damaged during backfilling, and the long construction period affects the construction of the next process.

[0032] The present invention will be further described below in conjunction with embodiments, the purpose of which is only to provide a better understanding of the content of the present invention. Therefore, the examples given do not limit the protection scope of the present invention. Embodiment 1:
[0033] refer to Figure 1 , Figure 2 , Figure 8 A basement exterior wall waterproofing membrane protective layer structure, from the wall to the backfill soil, includes a basement exterior wall 1, a waterproof bonding layer 2, a waterproofing membrane 3, a protection plate and backfill soil 5, wherein the protection plate is a prefabricated cement compression plate 4, the cement compression plate 4 includes a main body 401, the inner surface of the main body 401 is provided with support ribs 402, the support ribs 402 are distributed in a plum blossom shape, and the outer ends of the support ribs 402 are connected to the waterproofing membrane 3.
[0034] The inherent strength and structural design of the cement compression plate 4 ensure that the cement compression plate 4 will not be damaged. The support ribs 402 effectively support the interval between the main body 401 and the waterproofing membrane 3, isolating the backfill soil 5 from causing damage to the waterproofing membrane 3 during backfilling. After the basement waterproofing construction is completed, the cement compression plate 4 can be installed immediately. After the cement compression plate 4 is installed, the outer side of the cement compression plate 4 is ready for backfilling, and the backfill 5 can be backfilled immediately, which greatly reduces the waiting time. The cement compression plate 4 should be installed as the backfill soil is filled to speed up the construction progress. After the backfill soil 5 is backfilled, it generates lateral pressure on the cement compression plate 4, which naturally presses the cement compression plate 4 to the surface of the waterproofing membrane 3. Embodiment 2:
[0035] See also Figure 1 , Figure 2 The mortar 6 is filled in the space between the main body 401 and the waterproof membrane 3, so as to further firmly bond the cement compression board 4 and the waterproof membrane 3.
[0036] The outer ends of the support ribs 402 of the cement compression plate 4 directly contact the waterproofing membrane 3. In the scheme of Example 1 where no mortar 6 is filled for bonding, in order to prevent the cement compression plate 4 from tipping over before the backfill soil 5 is backfilled, the outer ends of the support ribs 402 are bonded and fixed to the waterproofing membrane 3. The bonding can be spot-coated adhesive bonding, which does not require a strong bonding force. The cement compression plate 4 will be further fixed after the backfill soil 5 is backfilled later. In the scheme of Example 2 where mortar 6 is used for bonding, the lateral pressure of the backfill soil 5 in the later stage can make the support ribs 402 and the waterproofing membrane 3 tightly pressed against each other, so that there is no leakage when the mortar 6 is poured. Whether the outer ends of the support ribs 402 are pre-bonded is an optional operation.
[0037] As an alternative, see Figure 3 The support rib 402 is in the shape of a longitudinal strip as a whole; the side of the support rib 402 is an inwardly concave arc 403. The long strip support rib 402 has high support strength. The inwardly concave arc 403 of the side design can form an anchoring structure at the outer end of the support rib 402 after the mortar 6 solidifies. The inner side of the mortar 6 is bonded to the waterproof membrane 3, and the outer side is bonded to the main body 401 of the cement compression plate 4. The support rib 402 serves as an anchoring structure of the cement compression plate 4 in the mortar 6.
[0038] In order to make the mortar 6 and the cement compression board 4 more firmly bonded, the surface of the support rib 402 is coated with an adhesive layer before pouring.
[0039] As an alternative, see Figure 4 , Figure 5 The upper end of the main body 401 of the cement compression plate 4 is provided with two symmetrical grooves 404 in the middle, and the lower end of the main body 401 of the cement compression plate 4 is provided with a protrusion 405 matching the grooves 404.
[0040] Specifically, the cement compression board 4 can be customized in different sizes according to the conditions of the basement outer wall 1 when it is produced in the factory, such as 1200mm in length, 600mm in width, and the thickness is set according to the backfill material. The support ribs 402 are evenly distributed, and the upper and lower discontinuities ensure the connectivity of the entire bonding cavity. Specifically, they can be 10mm in height, 250mm in length, 225mm in spacing, and arranged in a plum blossom shape.
[0041] The cement compression board 4 used in the utility model is a factory prefabricated structure, which is transported to the site in batches for centralized stacking; after the roll material construction is completed, the cement compression board 4 is immediately pasted; the cement compression board 4 is similar in appearance to the extruded board, and is similar in convenience to the extruded board, so it can be installed as a whole piece or assembled in multiple pieces; the cement compression board 4 is accumulated layer by layer from bottom to top, and earth backfilling can be carried out immediately after one layer is constructed, and the mortar 6 can be poured layer by layer, or it can be poured all at once after all the cement compression boards 4 are installed; when assembling, it can be as follows Figure 6 The upper and lower layers are aligned and assembled as shown, or Figure 7 As shown, the upper and lower layers are assembled in a staggered manner; if you want to increase the protection effect after backfilling is completed, pour cement mortar into the gap. After the mortar 6 is poured, it can be tightly connected with the coil and the cement compression plate 4, which can greatly improve the protection performance and extend the service life of the coil.
[0042] As an option, mortar 6 is ordinary cement mortar, and the mortar can be mixed with a proper amount of binder to improve cohesion, and the binder is 108 glue.
[0043] The beneficial effects of the utility model are as follows: 1) The construction is simple and of good quality. Compared with direct construction of cement mortar, the cement compression board 4 can greatly improve the construction efficiency. Compared with the extruded board, the cement compression board has higher strength and better supporting and protecting effect. 2) The cement compression board 4 designed in this scheme has good compressive performance because it has its own supporting ribs. After pasting, it can meet the conditions for backfilling, reducing the waiting time for construction. 3) The mortar 6 is selectively poured according to the working conditions. Since the backfilling has been completed, the poured mortar 6 tightly combines the waterproof membrane 3 with the cement compression board 4, which can significantly improve the role of protecting the structure.
[0044] The above description is only a preferred feasible embodiment of the present invention, and does not limit the scope of rights of the present invention. All equivalent changes made using the contents of the present specification and its drawings are included in the scope of rights of the present invention.
