Abstract
The invention discloses a method for discharging water in a pit through a steel bucket in the pit. According to the method for discharging water in the pit through the steel bucket in the pit, a hole is formed in the bottom of the cylindrical steel bucket (1), a gate valve (2) is installed in the orifice of the hole, waterstop rings (4) are welded to the surface of the outer wall of the steel bucket (1), the steel bucket is placed in the pit filled with centimeter-level stone (8), and then the periphery of the bottom of the steel bucket is filled with centimeter-level stone; a blind ditch is filled with dog-head-shaped stone (6), and water existing in other water leakage points is guided into the steel bucket from the orifice of the hole through the blind ditch; a water pump (3) is placed in the steel bucket so that water can be pumped. According to the method for discharging water in the pit through the steel bucket in the pit, it can be guaranteed that water falls into the steel bucket in the whole raft construction process, the whole foundation pit is in a water-free construction state, waterproof construction and other processes are greatly facilitated, the phenomenon that water leakage and cracks happen to a raft due to underground water is avoided, the concrete casting quality of the raft is guaranteed, and water discharging can be achieved conveniently and effectively.
Description
Technical field
The present invention relates to the water seal for deep foundation pit of building trade, is in a kind of hole, to cheat steel drum to fall water discharge method specifically.
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.
Summary of the invention
The object of the invention is to for above-mentioned deficiency of the prior art, provide and in a kind of hole, cheat steel drum and fall water discharge method.The present invention can keep whole raft plate construction stage steel drum 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 present invention adopts following technical scheme to be achieved:
In a kind of hole, cheat steel drum and fall water discharge method, its step is as follows:
A. the steel drum of column type (1) bottom opening gate valve (2), steel drum (1) outer wall surface welding seal ring (4) are installed in aperture;
B. in the construction of raft plate, dig the hole of dark 800mm at the place of leaking, and fill out the centimetre stone (8) that 100mm is thick 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 a dog stone (6), and cover with plastic sheeting (7), then by french drain, the water of other leakage points is introduced in hole and entered steel drum (1) by aperture;
E. putting into water pump (3) in steel drum (1) the inside draws water.
Described column type 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.
Feature of the present invention 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 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, 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 accompanying drawing 1-4 and embodiment, the present invention is further elaborated.
In a kind of hole, cheat steel drum and fall water discharge method, implementation step is: make the cylindrical steel drum (1) of a diameter 800mm ~ 1200mm, the thick column type of 5mm, height is determined by built plank thickness.Steel drum (1) bottom opening is also installed gate valve (2), the long steel drum of every 3000mm (1) is along surrounding welding seal ring (4), in the construction of raft plate, dig the hole of dark 800mm 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 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 introduced to dell and 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, in hole, to cheat steel drum and fall water discharge method, 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 is 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, 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.
