The basements are low-lying, so water collection wells are often required to facilitate drainage and avoid water seepage in the basements. At present, the cushion layers of basement water collection wells in the construction industry are all cast on site, that is, before the cushion layers are cast, the construction workers can only go down to the wells after the structural strength of the water collection wells reaches a certain requirement. This will greatly extend the construction period and reduce the construction efficiency, especially during the rainy season.

[0011] The rapid construction method for a water collection well cushion layer of the present invention prefabricates the water collection well cushion layer. When the water collection well is excavated to the bottom, the finished cushion layer can be immediately placed on the bottom of the pit, and then the workers can go down to carry out subsequent operations, which saves time and improves efficiency. At the same time, by arranging a cushion layer matching part of the prefabricated water collection well cushion layer and a foundation pit matching part in the water collection well foundation pit, rapid alignment can be achieved to ensure that the prefabricated water collection well cushion layer will not shake after being in place, has good stability and can further shorten the installation time, improve installation efficiency, and has good application prospects.

[0012] As the preferred technical solution:

[0013] In the rapid construction method of a water collection well cushion layer as described above, the foundation pit matching portion is a protrusion, and the cushion layer matching portion is a depression.

[0014] In the rapid construction method of a water collection well cushion layer as described above, the foundation pit matching portion is a depression, and the cushion layer matching portion is a protrusion.
