Embodiment
[0017] In specific implementation, such as figure 1 and figure 2 As shown, dig a drainage ditch 3 along the loose water slope 2, and dig a drainage inspection well 4 near the indoor floor 1 (the distance between the drainage inspection well 4 and the indoor floor 1 should not exceed 100 meters. ), and then connect the drainage ditch 3 with the drainage inspection well 4. Water-spreading slope 2, drainage ditch 3 and drainage inspection well 4 are smoothed with concrete to make a waterproof layer to prevent rainwater from seeping into the loess bearing layer under the indoor floor from the scattering slope 2, drainage ditch 3 and drainage inspection well 4, resulting in Indoor floor sinking. The width, depth and slope of the drainage ditch shall be determined according to the actual situation of the project.

The invention discloses a method and a structure for preventing a collapsible loess area indoor terrace from subsiding. According to the method, an open drainage channel is added beside an apron slope around a building, rainwater drained from a roof is discharged into a drainage water inspection well close to the building through the open drainage channel, so that the rainwater can be prevented from permeating a loess bearing stratum of the indoor terrace along the apron slope, and the subsiding of the indoor terrace can be avoided. According to the method, the rainwater can be effectively prevented from permeating the loess bearing stratum of the indoor terrace along the apron slope, and the subsiding of the indoor terrace due to collapse of the loess bearing stratum can be fundamentally prevented, and maintenance cost of the whole building can be saved. The width and depth of the open drainage channel and the drainage gradient are determined according to actual conditions of a project.
Description
technical field [0001] The invention relates to a method and structure for preventing indoor floor subsidence in collapsible loess areas, and belongs to the technical field of construction engineering foundations. Background technique [0002] In collapsible loess areas, the characteristic of collapsible loess is that when it encounters water, the loess will sink due to its own weight, so the drainage around the building is very important. If the drainage around the building is not done well, When the roof rainwater is drained down intensively, the water volume is very large and concentrated, and the rainwater will infiltrate into the loess bearing layer under the indoor floor along the water slope, and the floor will sink due to the collapsibility of the loess, and the entire indoor floor will be damaged. If it is cracked, it is necessary to re-excavate the indoor floor for treatment and restore it, resulting in a waste of maintenance costs, and it cannot fundamentally solv...
