Lower room has: outpatient service, image dept. of radiology, hyperbaric oxygen chamber, radiotherapy center, simulating chamber, information centre, pharmacy, Administrative Area etc., this
A little rooms all seem critically important, and ground requires also high.Referring to Fig. 1, the prior art is due to structure basis form and electromechanical tube sewer pipe
Line must must have an architectural construction layer total height on the ground that subsurface set aside pre-embedded, basement are finally completed to sole plate,
This architectural construction layer generally comprises surface layer, rigid layer, filled layer, drainage layer, and rigid layer is also known as rigid waterproof layer, usually
150 is thick, and C25/P6 water-proof concrete production, the interior diameter with reinforcing bar is 4, and the spacing between reinforcing bar is 200, is set as two-way
Single layer, and with pouring with troweling, wherein filled layer and the material of drainage layer require to backfill and meet compacting factor requirement, usually
Compacting factor is not less than 0.94, therefore each room floors correspond to this highly and just have a room heart backfilling material way, usually
Layer material is filled using plain earthen backfill, drainage layer material is using 300 thick medium coarse sand backfills.Using former basement room heart element earthen backfill
When scheme, existing a large amount of holes on live upper floor plate (each stairs port, elevator shaft mouth, daylighting garden, escalator mouth,
Post-cast strip whole audience openings, first and second phase interface, vestibule interface, pipe well mouth etc.) and outer wall of basement set aside pre-embedded hole, it is impossible to
Close these holes one by one to backfill and halt other processes and stop doing business, these holes will lead to certainly rainwater and construction water into
Enter basement, the result is that water, which will impregnate plain soil, becomes mud or spring soil, compacting factor is unable to reach former design requirement and is greater than etc.

Width, area are big, and sole plate, often with reversed beam, essence earthen backfill transport difficult on reversed beam, structure security risk is also big, construction
Slowly, normal need 3 months.And the present embodiment is simple and fast using foam concrete placings, completes within 1 month, shortens the backfill time 2
Month, be conducive to integrated engineering progress.Using the use scope of two ways extension foam concrete, one is mixed using foam
Solidifying soil alternatively descends the drainage layer between room floor and sole plate in architectural construction layer, this is to be based on facts have proved foam coagulation
Native air entrapment not necessarily all completely encloses, and has certain infiltration function；Another is to substitute basement using foam concrete
Drainage layer, filled layer and rigid layer between ground and sole plate in architectural construction layer become new filled layer, and rigid layer has
Water-proof function.For the second way, foam concrete dry density Ji other≤B08 of new filled layer, Qiang degree Ji other≤A3.5, and
Using surface press polish.In addition, adding waterproof layer and protective layer above new filled layer, waterproof layer and protective layer are in the foam coagulation
It is completed after native face troweling, prevention and treatment moisture influences the drying of the above room floors of basement upwards.It should be noted that for
Between having boiled water room, do not add waterproof layer and protective layer above new filled layer because this two layers inside architectural construction surface layer way
Through having.In this way, waterproof layer uses 1.5 thick polymer cement waterproof paints, meets wall and turns over 300, meets door and puts up door
300, protective layer uses 20 thickness 1:3 cement mortar.
