Metal cage 5, steel wire 6, ribs 7, draining pump 9, babinet platform 1 are the chamfered edge platform structure of bottom lock, the outside of babinet platform 1
Some ribs 7 are surrounded by, 1 lower center position of babinet platform is fixed with steel pipe 2,2 bottom of steel pipe and 1 bottom of babinet platform
Concordantly, steel pipe 2 is being fixedly connected with seal ring 4 at 1/3 height above 1 bottom of babinet platform, and ring flange bottom is fixed with the top of steel pipe 2
Lid 3,2 bottom of steel pipe are fixedly connected with metal cage 5, steel wire 6, bottom fixing connection steel plate seat 14, metal are equipped with around metal cage 5
Draining pump 9 is equipped with cage 5.
A kind of application method of deep foundation pit rigid water drainage platform device, comprises the following steps：
1) present apparatus is lifted in foundation pit using lifting equipment, surrounding blinding concrete is poured again after location determination is good,
Concrete in the range of ribs 7 thickeies, and ribs 7 is all embedded in concrete base after concrete has been poured, in metal cage 5
Interior placement draining pump 9, and drained into ponding on the outside of foundation pit by drainpipe 10；
2) draining pump 9 and drainpipe 10 of metal cage are taken out before pouring base concrete in babinet platform 1, by flange
Disk seal closes, i.e., 13 blending bolt 12 of rubber cushion is tightened on pad between flange head cover 11 and ring flange bottom cover 3, and guarantee is water-tight, because
Concrete base is all embedded in after base concrete has been poured for device, has prevented the generation of drainage；
3) when level of ground water exceedes bottom of foundation ditch absolute altitude, foundation pit surrounding sandstone is subject to the restriction of babinet platform 1 not send out
Life is caved in, and is less had underground water and is entered in babinet platform 1, and an anhydrous job platform is provided for next procedure construction.
In the present embodiment, steel plate box is welded (with ground into 60 ° of angles) according to the foundation pit slope size of engineering construction drawing
Platform 1, box height are base depth.The outside of babinet platform 1 sets support reinforcing rib 7 along surrounding, and ribs 7 is justified using Φ 18
