Description

Water guide wall structure of basement interior wall

This creation is a water-conducting wall structure applied to the basement interior wall. It mainly adopts dry construction method and uses modular building materials to achieve multiple functions such as rapid construction, space saving, good water conduction, moisture resistance and wall cancer prevention.

In densely populated metropolitan areas, in order to solve the problem of space use, basements are often excavated for parking lots, machine rooms, etc. Basements are usually waterproofed during excavation, but the buildings are getting old over time, or earthquakes Small cracks on the wall, or the geographical location of the building make the original waterproof measures unusable, resulting in damp and water seepage in the basement.

The basements of buildings in metropolitan areas are mostly remedial waterproofing works from the interior walls. There are many ways to waterproof the basement, one of which is the water-conducting wall construction method, that is, first find out the cause of the water seepage in the basement and perform water-stopping treatment, then build a water-conducting wall on the surface of the inner wall, and set up a drainage ditch on the ground below the water-conducting wall to allow the interior The water seepage in the wall is blocked by the water guide wall and then guided and concentrated to the drainage ditch below to be discharged to keep the basement dry and comfortable.

The construction method of the traditional water guide wall is the wet construction method. First, a layer of water guide plate is laid on the surface of the basement interior wall, and metal fixing parts, such as steel nails, are used to fix the water guide plate on the surface of the inner wall. The water guide plate is made of high-density polyethylene (HDPE) and has a waterproof sheet parallel to the inner wall. One side of the waterproof sheet is provided with a plurality of bumps, and the other side is formed at a position relative to each bump. The groove is sunken, and a layer of plastic net is arranged on the surface with multiple grooves on this side.

The plurality of projections of the above-mentioned water guide plate abut against the surface of the inner wall is to form a water guide gap between the waterproof sheet of the water guide plate and the surface of the inner wall, so that the water seepage of the inner wall can pass along the waterproof sheet and the surface of the inner wall. The water guide gap between them is drained to the drainage ditch on the ground for drainage, and after a layer of plastic mesh is set outside the water guide plate, a layer of wet cement mortar is laid on the surface of the plastic mesh by spraying machine or manual smearing, so that the wet cement mortar can be filled grooves on the water guide plate, and use plastic mesh to enhance the adhesion of the cement mortar and enhance the strength of the water guide plate. After the cement mortar is dry, carry out processes such as filling soil, leveling, painting and painting on the surface to complete the construction of the water guide wall .

In addition to laying a layer of wet cement mortar on the surface of the plastic net outside the water guide plate by spraying machine or manual smearing, another traditional construction method is to manually build a brick wall directly outside the water guide plate to isolate the water guide plate between the basement wall and the After the brick wall is in between, the surface of the brick wall is leveled, filled with soil, painted and painted; because this traditional construction method is to manually build a brick wall outside the water guide plate, it is also called a compound wall.

The construction method of the above-mentioned traditional water guide wall, whether it is spraying cement mortar on the outside of the water guide plate or manually building a brick wall, is a wet construction method. Although it has been practiced for many years, there are many shortcomings for a long time.

One is that the thickness of the brick wall is about ten centimeters. In addition to the thickness of the water guide plate and the subsequent steps of smoothing, filling, and painting, the thickness is even as high as 20 centimeters after completion. In urban areas where land is at a premium, many basements will have mechanical parking spaces along the inner walls, making brick walls a waste of space and difficult to construct. In addition, the sand, cement, brick fragments, etc. that fall during the construction of the wall will easily cause the blockage of the drainage ditch below. It will cause difficulties in overhauling, catching leaks and maintenance in the future.

The second is to use metal fixtures to fix the water guide plate on the surface of the inner wall during construction. After a long time, it will rust. On the one hand, the water guide wall is easy to crack. Seepage from the periphery of the rusted part of the metal fixtures caused black water spots on the surface of the water-conducting wall due to mold growth.

The third is that the plastic mesh may crack and separate from the water guide plate. In addition, the structure strength of the water guide plate itself is insufficient. Although some operators replace the plastic mesh with metal mesh to strengthen the structural strength of the water guide wall, the metal mesh will also be damaged after a long period of use. The problem of rust will affect the service life of the water guide wall.

In addition, during the construction process, in addition to the cement mortar mixing, spraying or bricklaying, the basement environment is likely to be humid, dusty, and dirty. After spraying or bricklaying, it takes a certain amount of time to wait for the cement to dry before surface leveling, In the process of filling soil, painting and painting, if the weather is bad, the construction days will continue to be extended, which is very inconvenient for people and vehicles to pass.

In view of the many deficiencies in the structure and construction process of the traditional water-conducting wall, the creator has accumulated years of research and practical experience in related fields, and specially created a water-conducting wall structure for the basement interior wall; after continuous testing and improvement, It is proved that this creation can overcome the problems of structural strength, service life, long construction period, easy to cause dirty construction environment, waste of space, and easy to cause blockage of drainage system in traditional water guide walls.
