Embodiment Construction
[0036] The present invention is described in detail below in conjunction with accompanying drawing:
[0037] Please refer to Figure 1 to Figure 8 , an embodiment of the present invention provides a drainage construction method for a basement floor, which may include:
[0038] Step 801, please refer to figure 1 , construct the cushion 100 in the foundation pit.
[0039] Step 802, please refer to figure 1 , construct the basement floor 200 on the cushion layer 100 .
[0040] Step 803, please refer to Figure 2 to Figure 3 , constructing the blind groove 210 downward along the upper surface of the basement floor 200 , the blind groove 210 includes a buried groove 211 in a flat section, and drainage grooves 212 located on inclined sections on both sides of the buried groove 211 . The slope angles of the drainage grooves 212 on both sides may be the same or different. The angles of the slopes of the drainage grooves 212 are the same in order to avoid excessive water accumula...

The invention discloses a drainage construction method for a basement bottom plate. The drainage construction method comprises the steps that the basement bottom plate is constructed in a foundation pit; a blind groove is constructed downwards along the upper surface of the basement bottom plate, and the blind groove comprises a buried groove of a flat section and drainage grooves located in slope sections of the two sides of the buried groove; a drainage pipe is laid in the buried groove; water storage and drainage plates are laid on the basement bottom plate along the two sides of the drainage pipe, and the water storage and drainage plate on each side covers the corresponding drainage groove and is erected above the drainage pipe; and a prefabricated drainage ditch is laid above the drainage pipe through a mortar layer or a concrete layer. According to the method, the construction efficiency of the waterproof engineering of the basement bottom plate can be improved, the construction period is shortened, and the construction difficulty is reduced.
Description
technical field [0001] The invention relates to the field of construction engineering, in particular to a drainage construction method for a basement floor. Background technique [0002] For basement buildings with deep foundation pits and high groundwater levels, the waterproofness of the basement floor is an important part of basement waterproofing. At present, most basement floor waterproofing adopts the combination of drainage and anti-proof, that is, before the construction of the basement floor building surface, a layer of waterproof paint is first applied for waterproofing, and then a storage and drainage board is laid on it for water drainage. By pouring the construction drainage ditch on the basement floor and reserving drainage holes on the drainage ditch, it is ensured that the water in the storage drainage plate flows into the drainage ditch through the drainage holes of the drainage ditch, and then discharged into the water collection well. The disadvantage is ...
