In a kind of hole, cheat steel drum and fall dewatering installation, comprise the steel drum (1) of column type, described steel drum (1) bottom opening and gate valve (2) is installed in aperture, steel drum (1) outer wall surface welding seal ring (4), dig the hole of dark 800mm at the place of leaking, fill out the centimetre stone (8) that 100mm is thick in the bottom in hole, described dell is connected by french drain with other leakage point, steel drum (1) is put into the hole of filling in a centimeter stone (8), then use a centimeter stone (8) to fill up steel drum (1) bottom surrounding, finally put into the water pump (3) for drawing water in steel drum (1) the inside.The utility model can keep whole raft plate construction stage steel drum all at precipitation, make whole foundation ditch in anhydrous Construction State, advantageous particularly to waterproof construction and other operations, can not cause because of underground water the raft plate phenomenons such as cracking of leaking, when having ensured raft plate concrete pouring quality, allow yet and fall drainage works and become easily and effectively.
Description
Technical field
The utility model is the device for water seal for deep foundation pit, is specifically in a kind of hole, to cheat steel drum to fall dewatering installation.
Background technology
The engineering of constructing than more rich place at underground water, particularly deep-foundation pit engineering, underground water yield is larger, must take corresponding measures of preventing water to ensure carrying out smoothly of construction in construction.
The method of water seal for deep foundation pit has conventionally: water-stop curtain, well-points dewatering and gutter; But have the deficiencies such as long, complicated operation of duration and cost be higher, water-stop curtain can become very poor or almost there is no effect the stagnant water effect that is gravel layer at construction layer.
Utility model content
The purpose of this utility model is for deficiency of the prior art, provides in a kind of hole, to cheat steel drum and fall dewatering installation.The utility model can keep whole raft plate construction stage steel drum all at precipitation, make whole foundation ditch in anhydrous Construction State, advantageous particularly to waterproof construction and other operations, can not cause because of underground water the raft plate phenomenons such as cracking of leaking, when having ensured raft plate concrete pouring quality, allow yet and fall drainage works and become easily and effectively.
The utility model adopts following technical scheme to be achieved:
In a kind of hole, cheat steel drum and fall dewatering installation, comprise the steel drum (1) of column type, described steel drum (1) bottom opening and gate valve (2) is installed in aperture, steel drum (1) outer wall surface welding seal ring (4), dig the hole of dark 800mm at the place of leaking, fill out the centimetre stone (8) that 100mm is thick in the bottom in hole, described dell is connected by french drain with other leakage point, steel drum (1) is put into the hole of filling in a centimeter stone (8), then use a centimeter stone (8) to fill up steel drum (1) bottom surrounding, finally put into the water pump (3) for drawing water in steel drum (1) the inside.
Described steel drum (1) diameter is that 800mm ~ 1200mm, wall thickness are 5mm, and height is determined by built plank thickness.
Described steel drum (1) welds one seal ring (4) along the every 3000mm of short transverse.
In described french drain, insert a dog stone (6), and cover with plastic sheeting (7).
Described steel drum (1) is placed on upper its top of a centimeter stone (8) and spills raft plate face (9) 50mm, and centimetre stone (8) fills up along steel drum (1) bottom surrounding.
Feature of the present utility model is:
1, water pump is put into steel drum, and hole bed mud sand can not stop up water pump;
2, when raft plate is built, water pump does not stop pumping, and underground water can not impact building of raft plate.
3,, after raft plate has been built, underground water continues to extract out by the water pump in steel drum, can not cause because of underground water raft plate to leak.
4,, after raft plate curing time finishes, can be simply reach the object of sealing by closing gate valve in steel drum.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further elaborated:
Cheat steel drum for the hole of water seal for deep foundation pit and fall dewatering installation, make the cylindrical steel drum (1) of diameter 800mm ~ 1200mm, a thick 5mm, height is determined by built plank thickness.Steel drum (1) bottom opening is also installed gate valve (2), the every 3000mm of outer wall surface of steel drum (1) is long along surrounding welding seal ring (4), in the construction of raft plate, dig the hole of dark 800mm at the place of leaking, and with centimetre stone (8) hole bottom fill out 100mm thickness, the water of other leakage point is incorporated in hole by french drain, then steel drum (1) is put into the hole of filling in a centimeter stone (8), then use a centimeter stone (8) to fill up steel drum (1) bottom surrounding; In french drain, insert a dog stone (6), and cover with plastic sheeting (7), by french drain, the water of other leakage points is incorporated in hole and enters steel drum (1), the water pump (3) that last resort is placed on steel drum (1) the inside draws water.In whole work progress, underground water can not impact.
From accompanying drawing 1, the structure of water seal for deep foundation pit steel drum: in steel drum (1) bottom, several gate valves (2) are installed, seal ring (4) is welded on steel drum (1) outer wall surface surrounding, and water pump (3) is put into steel drum (1) and drawn water.
From accompanying drawing 2, seal ring (4) is welded on steel drum (1) around, and gate valve (2) is arranged on steel drum (1) bottom.
From accompanying drawing 3, a dog stone (6) fills up whole french drain along soil layer (5), then uses plastic sheeting (7) to cover french drain.
From accompanying drawing 4, centimetre stone (8) is filled out at the upper 100mm of soil layer (5) thick, and it is upper that steel drum (1) is placed on a centimeter stone (8), and centimetre stone (8) fills up along steel drum (1) bottom surrounding, and steel drum (1) top spills raft plate face (9) 50mm.
