The box body platform is of a reversed prismatic table structure with the closed bottom. A plurality of reinforcing ribs is arranged around the outer side of the box body platform. The steel tube is fixed at the central position of the bottom of the box body platform. The bottom of the steel tube is flush with the bottom of the box body platform. The water-stop ring is fixedly connected at the position, corresponding to one third of the height above the bottom of the box body platform, of the steel tube. The flange plate bottom cover is fixed on the top of the steel tube. The metal cage is fixedly connected at the bottom of the steel tube. The steel wire mesh is arranged around the metal cage, and the bottom of the metal cage is fixedly connected with a steel plate base. The drainage pump is arranged inside the metal cage. The deep foundation pit rigidity drainage platform device has the advantages of being capable of effectively lowering ground water levels, reducing drainage project amounts, preventing a foundation pit from collapsing, shortening drainage project periods, saving project cost and guaranteeing project quality, simple in structural design and convenient to operate.
Description
Technical field
The utility model relates to the realm of building construction, relates in particular to a kind of deep foundation ditch rigid drainage stage apparatus.
Background technology
The development that highrise building is at full speed, foundation depth constantly refreshes, and the deep foundation ditch drainage works is particularly important.When run into sandstone bearing stratum and groundwater table when higher plumbing work bring very big difficulty.Traditional way is to adopt the precipitation well, and whole groundwater table in the foundation ditch is down to 500mm(under the work layers such as elevator foundation ditch, sump because absolute altitudes such as elevator foundation ditch, sump are the minimum absolute altitude of foundation ditch).This kind way dewatering project amount is big, long construction period, inefficiency, the effluent cost height, in case the groundwater table of controlling well useless, foundation ditch very easily caves in, and bed course and waterproofing course destroy easily, bring very big duration and economic loss to engineering.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this utility model provides a kind of deep foundation ditch rigid drainage stage apparatus, can be to sandstone bearing stratum, groundwater table higher effective drainage of foundation pit, can dewatering, prevent that foundation ditch from caving in, for the next procedure construction provides anhydrous job platform.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of deep foundation ditch rigid drainage stage apparatus, comprise the casing platform, steel pipe, the flange bottom, seal ring, metal cage, gauze wire cloth, ribs, drainage pump, the chamfered edge platform structure that described casing platform is bottom lock, the casing platform is provided with some ribs around the outside, casing platform bottom center fixed-site has steel pipe, the steel pipe bottom is concordant with casing platform bottom, steel pipe 1/3 is highly located fixedly connected seal ring above casing platform bottom, steel pipe top fixedly has the flange bottom, the fixedly connected metal cage in steel pipe bottom, be provided with gauze wire cloth around the metal cage, bottom fixing connection steel plate seat is provided with drainage pump in the metal cage.
Described casing platform bottom Corner Strapped is useful on the suspension ring of lifting.
Compared with prior art, the beneficial effects of the utility model are:
Effectively dewatering reduces the drainage works amount, prevents that foundation ditch from caving in, and shortens the draining duration, saves engineering cost, guarantees workmanship, and structure design is simple, and is easy to operate.

The specific embodiment
Below in conjunction with Figure of description the utility model is described in detail, but should be noted that enforcement of the present utility model is not limited to following embodiment.
See Fig. 1-Fig. 4, a kind of deep foundation ditch rigid drainage stage apparatus, comprise casing platform 1, steel pipe 2, flange bottom 3, seal ring 4, metal cage 5, gauze wire cloth 6, ribs 7, drainage pump 9, the chamfered edge platform structure that described casing platform 1 is bottom lock, be provided with some ribs 7 around casing platform 1 outside, casing platform 1 bottom center fixed-site has steel pipe 2, steel pipe 2 bottoms extend to casing platform 1 below 500-600mm, steel pipe 2 1/3 is highly located fixedly connected seal ring 4 above casing platform 1 bottom, flange bottom 3 is fixedly arranged at steel pipe 2 tops, the fixedly connected metal cage 5 in steel pipe 2 bottoms, be provided with gauze wire cloth 6 around the metal cage 5, be provided with drainage pump 9 in the metal cage 5.
Described casing platform 1 bottom Corner Strapped is useful on the suspension ring 8 of lifting.
Embodiment:
See Fig. 1 and Fig. 2, put sloping size (becoming 60 ° of angles with ground) weldering casing platform 1 processed according to the foundation ditch of engineering construction drawing, casing platform 1 highly is base depth.Casing platform 1 outside is along arranging support reinforcing rib 7 all around, and ribs 7 adopts Φ 18 round steel to be soldered to casing platform 1 outside, and spacing is 400mm, and horizontal length is 500mm, extends the concrete cushion bottom and prevents that this device from toppling.Steel pipe 2(Φ 300mm is installed in casing platform 1 bottom center position), height 700mm and will be lower than foundation ditch concrete floor thickness, steel pipe 2 welded top flange bottoms 3,1/3 height welding steel seal ring 4 on steel pipe.At four Φ of casing platform 1 bottom, four welded corner joints, 20 round steel suspension ring 8, be used for lifting.
Below casing platform 1, namely steel pipe 2 bottom weld metal cages 5 highly between 500-700mm, wrap up with gauze wire cloth 6 around the metal cage 5, and bottom weldable steel panel seat 14 prevents that sandstone from entering in the cage.
See Fig. 3, utilize crane gear that this device is lifted in the foundation ditch, the position determines that circumferential concrete and blinding concrete are being built in the back well, the thickening of ribs 7 scope inner concretes.Meanwhile in metal cage 5, place drainage pump 9, and by gutter 10 ponding is drained into the foundation ditch outside.Even if groundwater table surpasses foundation ditch bottom absolute altitude, the restriction that sandstone is subjected to casing platform 1 around the foundation ditch can not caved in, and does not more have underground water and enters in the casing platform 1, has guaranteed that the scope of operation do not have ponding, for the next procedure construction provides a waterless operation platform.
Took out drainage pump 9 and gutter 10 before building the foundation ditch concrete, with the flange sealing, namely rubber cushion 13 is also tightened with screw 12 on flange top cover 11 underlays, sees Fig. 4, guarantees water-tight.Build the foundation ditch concrete at last.Because device all is embedded in concrete base after having built concrete, workmanship has been guaranteed in the generation of having stopped drainage.
The utility model is dewatering effectively, reduces the drainage works amount, prevents that foundation ditch from caving in, and shortens the draining duration, saves engineering cost, guarantees workmanship, and structure design is simple, and is easy to operate.
