Abstract
Steel drum Yield rainfall relation method is cheated in a kind of hole, adopt the steel drum of column type, steel drum (1) bottom opening of column type also installs gate valve (2) in aperture, steel drum (1) outer wall surface welding seal ring (4), steel drum is put into the hole of filling in a centimeter stone (8), then fill up surrounding bottom steel drum with centimetre stone; In french drain, insert dog head stone (6), then enter steel drum in the water of other leakage points introducing hole by aperture by french drain; Inside steel drum, put into water pump (3) draw water, the present invention can keep whole raft plate construction stage steel drum at precipitation, whole foundation ditch is made to be in anhydrous Construction State, to waterproof construction and other operations advantageous particularly, raft plate can not be caused because of underground water to leak the phenomenons such as cracking, while ensure that raft plate concrete placings quality, also allow Yield rainfall relation work become easily and effectively.
Description
Technical field
The present invention relates to the water seal for deep foundation pit of building trade, cheat steel drum Yield rainfall relation method in a kind of hole specifically.
Background technology
Carry out the engineering, particularly deep-foundation pit engineering of constructing than more rich place at underground water, underground water yield is comparatively large, 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 usually: water-stop curtain, well-points dewatering and gutter; But there is duration longer, complicated operation and the deficiency such as cost is higher, water-stop curtain can become very poor to the stagnant water effect at construction layer being gravel layer or almost not have effect.
Summary of the invention
The object of the invention is to for above-mentioned deficiency of the prior art, provide in a kind of hole and cheat steel drum Yield rainfall relation method.The present invention can keep whole raft plate construction stage steel drum at precipitation, whole foundation ditch is made to be in anhydrous Construction State, to waterproof construction and other operations advantageous particularly, raft plate can not be caused because of underground water to leak the phenomenons such as cracking, while ensure that raft plate concrete placings quality, also allow Yield rainfall relation work become easily and effectively.
The present invention adopts following technical scheme to be achieved:
Cheat steel drum Yield rainfall relation method in a kind of hole, its step is as follows:
A. column type steel drum (1) bottom opening and aperture install gate valve (2), steel drum (1) outer wall surface welding seal ring (4);
B., in the construction of raft plate, dig the hole of dark 800mm at the place of leaking, and fill out the thick centimetre stone (8) of 100mm in the bottom in hole;
C. 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;
D. in french drain, insert dog head stone (6), and cover with plastic sheeting (7), then enter steel drum (1) in the water of other leakage points introducing hole by aperture by french drain;
E. put into water pump (3) in steel drum (1) the inside to draw water.
Described column type steel drum (1) diameter is 800mm ~ 1200mm, wall thickness is 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.
Feature of the present invention is:
1, steel drum put into by water pump, and hole bed mud sand can not block water pump.
2, time raft plate is built, water pump does not stop pumping, and in whole work progress, 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, and raft plate can not be caused because of underground water to leak.
4, after raft plate curing time terminates, the object of sealing can be reached simply by the gate valve of closing in steel drum.

Detailed description of the invention
Below in conjunction with accompanying drawing 1-4 and embodiment, the present invention is further elaborated.
Cheat steel drum Yield rainfall relation method in a kind of hole, implementation step is: the cylindrical steel drum (1) making a thick column type of diameter 800mm ~ 1200mm, 5mm, and height is determined by built plank thickness.Steel drum (1) bottom opening also installs gate valve (2), the long steel drum of every 3000mm (1) is along surrounding welding seal ring (4), in the construction of raft plate, the hole of dark 800mm is dug at the place of leaking, and it is thick to fill out 100mm with centimetre stone (8) in bottom, the water of other leakage point is incorporated in hole by french drain, again steel drum (1) is put into the hole of filling in a centimeter stone (8), then a centimeter stone (8) is used to fill up steel drum (1) bottom surrounding, insert dog head stone (6) in french drain, and cover with plastic sheeting (7).By french drain, the water of other leakage points is introduced dell to be entered by steel drum (1) bottom port, finally put into water pump (3) in steel drum (1) the inside, draw water.In whole work progress, underground water can not impact building of raft plate.
From accompanying drawing 1, cheat steel drum Yield rainfall relation method in hole, gate valve (2) is arranged on steel drum (1) bottom, and seal ring (4) is welded on steel drum (1) 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, can adjust open amount.
From accompanying drawing 3, dog head 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 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.
