Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rolled material waterproof protective layers, in particular to a foundation pit side wall protection plate. Background Art
[0002] For the side walls of the underground slab foundation, the common method of protecting the waterproof layer is to set a fiberglass mesh cloth on the surface of the waterproof layer and then apply cement mortar.
[0003] For underground side walls, there are three common methods for protecting the waterproof layer: 1. Setting a glass fiber mesh cloth on the surface of the waterproof layer, and then applying cement mortar; 2. Pasting extruded board on the surface of the waterproof layer; 3. Setting a brick wall on the surface of the waterproof layer.
[0004] In the above-mentioned existing waterproof protective layer setting method for the side wall of the underground floor pedestal and the underground side wall, the method of hanging mesh and cement mortar coating is adopted. For the side wall with greater depth, the cement mortar is prone to flow and fall and uneven coating. The insufficient thickness is easy to be damaged by the steel bars of the subsequent construction, and the excessive thickness is easy to cause cracks due to the inconsistent drying speed inside and outside. At the same time, it takes a certain amount of time for the cement mortar to dry after construction, which has a certain impact on the construction period; if the wet method is used at the construction site, it will cause environmental pollution.
[0005] In the method of using extruded boards for protection by gluing, nails are usually used to fix the extruded boards. Since the fixing nails penetrate the waterproof layer, the continuity of the waterproof layer will be affected, leaving a risk of leakage. In addition, the extruded boards are generally spliced together, and the board seams are not sealed, which will also significantly affect the waterproof effect.
[0006] In the brick wall protection method, bricks are bonded together with cement mortar, which takes a long time. For the deeper side walls, the brick wall is heavy, which poses a certain safety hazard and is also expensive. For the inclined pedestal, bricks are difficult to align, making construction difficult.
[0007] Therefore, it is necessary to provide a foundation pit side wall protection material that can achieve simple and efficient construction and has good waterproof protection function. Utility Model Content
[0008] The purpose of the utility model is to provide a foundation pit side wall protection plate which can realize simple and efficient construction and has good waterproof protection function.
