2 application numbers are: the Chinese patent of CN201210200958.6 discloses " a kind of basement waterproofing structure structure and construction method " a kind of basement waterproofing structure structure and construction method, belongs to building operations structurally waterproof technical field.Waterproof construction structure is mainly made up of following structure: element soil; Element concrete bed course; Water-tight concrete base plate; Graded broken stone drainage blanket; Nonwoven separation layer; Steel concrete surface layer; Gutter; PVC gutter; Brick wall; Outer wall of basement.In this patent, the water in drainage blanket is dredged to gutter, the water in gutter often observation is drained in time, can not realize self-draining modern method.And do not seal measure bottom steel concrete surface layer, once underground water is arranged not in time, will make steel concrete surface layer cracking.The 2nd patent is also not suitable for applying in basement sole plate ground face thickness exceedes the engineering of 1m.And this patent is all to form on the basis that has overcome above shortcomings.
3 application numbers are: the Chinese patent of CN201310077111.8 discloses " antiseepage drainage blanket structure and construction method ", this disclosure of the invention a kind of antiseepage drainage blanket structure and construction method, described construction method comprises the following steps: cast one basement water resistant base plate, and in the reserved collecting well of described basement water resistant base plate, synchronize the sidewall of collecting well described in monobloc cast with described basement water resistant base plate; According to design height, pre-buried plural gutter in the sidewall of described collecting well; On described basement water resistant base plate, lay a drainage blanket, the first end of described gutter connects described drainage blanket, and the second end of described gutter connects described collecting well; In described drainage blanket upper one roof support with reinforced concrete, described roof support with reinforced concrete connects the sidewall of described collecting well.In this patent, the water in drainage blanket is discharged to collecting well, the water in collecting well can not be realized self-draining modern method.And do not seal measure bottom roof support with reinforced concrete, once underground water is arranged not in time, will make roof support with reinforced concrete cracking.And this patent is also not suitable for applying in basement sole plate ground face thickness exceedes the engineering of 1m.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, provide a kind of simple in structure, construction cost is low, reach good waterproof hydrophobic effect, the hydrophobic constructing structure of a kind of Novel underground chamber waterproof that can reduce basement sole plate buoyancy, increase work efficiency simultaneously.
The hydrophobic constructing structure of a kind of Novel underground of the present utility model chamber waterproof, it comprises the sole plate that is laid on successively from bottom to up waterproof roll, the fish tail and waterproof layer on foundation pad and has rigid self-waterproof function, collecting well is connected with sole plate, bottom at the described borehole wall that catchments has inlet opening, top at the described borehole wall that catchments has drain hole, in described drain hole, is inserted with gutter; On the described sole plate around collecting well, be disposed with from bottom to up grating cobble drainage blanket, nonwoven layer, sand cushion, rubble grout blanket and surface layer, described rubble grout blanket is connected with drain hole, described grating cobble drainage blanket is connected with inlet opening, and described gutter is laid in rubble grout blanket.
The beneficial effect of the utility model structure is: basement sole plate draining system can insert backfill and ground construction after basement construction completes in any time, and needn't wait until basement all complete and check leakproof after just carry out above work, increase work efficiency.By the draining system on sole plate and the combination of ground gutter, percolating water on sole plate and ground surface water all can be drained in collecting well, when water level in collecting well reaches certain height, automatically start drainage pump draining, to guarantee the dry state on basement ground, guarantee normal usage function.
