Specific embodiment
It referring to Fig.1, is a kind of base pit dewatering structure disclosed by the utility model, including supporting filtering wall 1, bed course 2, draining
Pipe 3, water pump 4 and water level controller 5, supporting filtering wall 1 is separately positioned on the side-walls of 6 surrounding of foundation pit and foundation pit is close in side
6 side walls carry out supporting for the side wall to foundation pit 6, while can also be stopped to silt and be filtered when silt is gushed out,
Prevent it from pouring in the inside of foundation pit 6.
Bed course 2 is laid on the bottom of foundation pit 6, for improving soil matrix, increases the stability of water, prevents soil matrix by larger
It deforms when load.Bed course 2 includes earthwork filled layer 21 and is injected in the concrete layer 22 of 21 upper surface of cubic metre of earth filled layer,
6 bottom of foundation pit is more soft due to seeping water, inconvenient that precipitation apparatus and supporting filtering wall 1 are installed and operated,
Infiltration is diluted by the filling earthwork, then earthwork filled layer 21 is reinforced by gunite concrete, forms stable knot
Structure.
Referring to Fig.1, for the middle concave part of bed course 2 at dewatering well 23, the side wall of 23 surrounding of dewatering well is slope, when water is from base
When the side wall in hole 6 penetrates into, the bottom of dewatering well 23 can be converged in along inclined-plane, to exclude, to empty by ponding, prevents its accumulation
At the bed course 2 of 23 surrounding of dewatering well, inconvenience operation, and then the period of draining is reduced, reduce working efficiency.
Drainpipe 3 is embedded in bed course 2, and one end protrudes into dewatering well 23, the other end be vertically arranged and stretch out foundation pit 6 to
Outside, water pump 4 is mounted in dewatering well 23 and is connected with drainpipe 3, for taking out the water of 23 bottom of dewatering well along drainpipe 3
Out, to realize precipitation.Non-woven fabrics can be wrapped up in the water inlet of water pump 4 as needed, silt is filtered with reaching
Effect.Water level controller 5 is mounted on the side in foundation pit 6 and being located at water pump 4, for controlling the start and stop of water pump 4, to realize
The purpose of the automatic precipitation of foundation pit 6 makes it observe the water content of dewatering well 23 incessantly without staff, and then saves big
The man power and material of amount reduces the cost of construction.
When the water level in foundation pit 6 is excessively high, water level controller 5 transmits a signal to control system, opens to control water pump 4
It is dynamic, carry out draining；When the water level in foundation pit 6 is too low, water level controller 5 transmits a signal to control system, to control
The phenomenon that water pump 4 processed is closed, and prevents dry combustion method from pumping.
Referring to Fig.1, further, the upper surface of bed course 2 is equipped with waterproof layer 7 and causes to pad for preventing ponding from permeating downwards
The soil property of layer 2 and 6 bottom of foundation pit is soft, influences the stability of supporting filtering wall 1.
Bed course 2 is set as waterproof roll, with good waterproofness and flexibility, convenient for according to requiring to be laid with.
Referring to Figures 1 and 2, supporting filtering wall 1 includes framework of steel reinforcement 11, intensive wire netting 12 and geotextiles 13, reinforcing bar
Frame 11 is made of the staggered reinforcing bar unit of several transverse and longitudinals, and intensive wire netting 12 is welded on framework of steel reinforcement 11 far from 6 side wall of foundation pit
Side, for effectively being stopped to biggish stone, soil block.Geotextiles 13 are coated on intensive wire netting 12 far from reinforcing bar
The side of frame 11 prevents it from flowing into the bottom of foundation pit 6 with water for being filtered to tiny silt.
The downside of framework of steel reinforcement 11 is extended with more vertical supporting reinforcing bars 14, when installation, makes framework of steel reinforcement 11 far from intensive
6 inner wall of foundation pit is close in the side of wire netting 12, and then vertical supporting reinforcing bar 14 is plugged in bed course 2, for filtering to supporting
Wall 1 is fixed, and the free end of vertical supporting reinforcing bar 14 is taper, in order to reduce the resistance in installation process.
Referring to Figures 1 and 2, framework of steel reinforcement 11 is vertically connected with more cross-brace steel far from the side of intensive wire netting 12
Muscle 15 when installation, is first plugged on pad for vertical supporting reinforcing bar 14 is oblique for further strengthening the stability of supporting filtering wall 1
In layer 2,1 righting of wall then is filtered into supporting, is close to it with the side wall of foundation pit 6, at this point, cross-brace reinforcing bar 15 is plugged on base
In the side wall for cheating 6 surroundings.
Several hangnails 16 being obliquely installed are connected on vertical supporting reinforcing bar 14 and cross-brace reinforcing bar 15, for increasing
A possibility that withdrawal resistance and stability of wall 1 are filtered in supporting, reduce its run-off the straight.
Referring to Fig.1, since the factor of installation is it is possible that gap between adjacent supports filtering wall, when water is filtered by supporting
It after wall 1 is gushed out, has a small amount of silt and is flowed together with water, to avoid silt from flowing in dewatering well 23, in the oblique of dewatering well 23
Face and bottom are laid with stone filter layer 8, and water pump 4 is made to be located at the upper surface of stone filter layer 8.
When the water flow for carrying a small amount of silt is dropped down to stone filter layer 8, stone filter layer 8 carries out blocking and mistake to silt
Filter, to further reduced a possibility that water pump 4 is blocked.
The embodiment of present embodiment is the preferred embodiment of the utility model, and not limitation is originally practical new according to this
The protection scope of type, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by practical
Within novel protection scope.
