In a kind of specific embodiment, the groundwater reclaim provided by the utility model for base pit dewatering purifies dress
It sets, including the matrix 1 that water inlet end is connect with base pit dewatering net, matrix 1 is equipped with multiple drainage layers for being used to filter precipitation, adjacent
Drainage interlayer was equipped with the network of rivers 2, under the premise of guaranteeing that water flow passes through, the medium between each drainage layer was effectively prevent mutually to mix
Together.Opening is equipped on matrix 1 with drainage layer corresponding position, opening is equipped with openable and closable 7 component of dustproof cover.
Matrix 1 is preferably steel pipe etc., and multiple drainage layers are arranged on matrix 1, can according to different drainage demand drainage layers
It for identical or different setting, crosses the network of rivers 2 and adjacent drainage interlayer is set, to improve drainage effect, in order to be needed more in drainage layer
Facilitate taking-up when changing, is open in matrix 1 and the setting of drainage layer corresponding position, 7 component of dustproof cover, 7 component of dustproof cover are set in opening
It can ride upon in opening, when needing to change drainage layer, open 7 component of dustproof cover and take out drainage layer realization replacement.
Using groundwater reclaim purification device provided by the utility model, pass through the multiple drainage layers pair being arranged on matrix 1
Drainage of foundation pit is filtered, and is simply convenient for being arranged by the way that its structure is directly arranged on matrix 1, builds sedimentation basin without excavating,
And without being modified to former flowing line, device, which is connect, can be realized filtering in the end of draining official website, and multiple drainage layers are real
Existing different drainages requirements, and when drainage layer needs to change, can realize the replacement of drainage layer by 7 component of dustproof cover.
Specifically, drainage layer includes the cobble drainage layer 3 set gradually along close water inlet end side, 4 and of rubble drainage layer
Quartzy drainage layer 5, opening punishment corresponding to the top of cobble drainage layer 3, rubble drainage layer 4 and quartzy drainage layer 5 on matrix 1
It She You not 7 component of dustproof cover.
Drainage of foundation pit is filtered step by step respectively by cobble drainage layer 3, rubble drainage layer 4 and quartzy drainage layer 5, when
So, in other embodiments, can also be with the drainage layer of self-setting other forms, such as microorganism drainage layer, it can be according to reality
It needs to be configured, it is within the protection scope of the present utility model.Wherein, dustproof cover 7 is respectively set above each drainage layer
Component, with when one of drainage layer needs to change, other drainage layers guarantee filtering effect without opening to prevent pollutant from entering
Fruit.
In one embodiment, 7 component of dustproof cover includes the dustproof cover 7 and be set to dust-proof that both ends are erected on respectively in opening
The load board 6 of 7 top of lid, one end of load board 6 and matrix 1 are hinged.Dustproof cover 7 is loaded by load board 6, is prevented
The tilting of dirt lid 7 pollutes object and enters in matrix 1, and one end of load board 6 can be realized hingedly by bolt and matrix 1, is loading
Mounting hole is respectively set on plate 6 and matrix 1, bolt is realized by mounting hole and fixed, and in other embodiments, can also voluntarily be set
Fixed form is set, it is within the protection scope of the present utility model.
In one embodiment, matrix 1 is specially bellows.Bellows has chemical stability relative to conventional cement pipe
And resistance to ag(e)ing, the acid and alkali substance in general soil will not damage it, weight is light compared to traditional pipe of cement,
Facilitate installation and is used in turn.The outer wall of bellows wave structure in a ring, enhances the rigidity of tubing, to enhance pipeline pair
The resistance of soil load prevents drainage layer from being squeezed by the external world and reducing water purification efficiency.The low-temperature resistant and shock resistant performance of bellows
More preferably, special protective measures need not be taken in -30 DEG C or more constructions, winter construction is convenient.Bellows can slightly be bent, no
It by a degree of differential settlement on ground, and can not have to be laid on pipe fitting, directly be layered in the groove slightly dug, save
Shi Shengli.Bellows price is low, long service life, improves the turnover rate of the present apparatus.
Further, pre-determined distance, preferably 5cm, to prevent sewage from overflowing are equipped between the laying top surface of drainage layer and opening
Out.
Further, the two sides of matrix 1 are respectively provided with the fixing piece of support substrate 1.Fixing piece can be specially wood
The structures such as side or steel pipe.
In a kind of specific embodiment, the excavation 30m long at base pit dewatering least significant end, the groove of 0.8m wide, 0.8m depth,
Transfer the present apparatus.Flitch is set in channel bottom, device is fixed, skew occurs for pipeline when preventing water flow excessive, influences clear
The use of silt mouth.Groove is simply gone along with sb. to guard him, dredging mouth is reserved in outside.Water quality monitoring is periodically carried out, is such as found
Water purification efficiency reduces or the decline of water purification quality, drainage layer can be carried out replacement cleaning by dredging mouth.
Water flow enters end purification device, and by cobble drainage layer 3, rubble drainage layer 4 be can reach after quartzy drainage layer 5
The requirement of construction water grade can continue to connect the present apparatus, to realize the water purification of more stages if any other water purifications requirement.Bellows
For caliber 500mm standard pipe, it can be convenient and be directly connected to construction site precipitation system, realize turnover.The present apparatus is by cobble
Drainage layer 3, rubble drainage layer 4, quartzy drainage layer 5 are directly arranged among pipeline, can save the process excavated and build sedimentation basin,
It uses manpower and material resources sparingly.Water flow is directly purified by bellows, compared to using after being precipitated into sedimentation basin, is had
It is high-efficient, the small advantage of occupied area, and possess preferably filtering effect compared to sedimentation basin in the faster situation of the flow velocity of water
Fruit.Corrugated pipe connector needs and the base pit dewatering net of 500mm caliber is used cooperatively, and the drainage pipeline of other bores need to be connect using variable diameter
Head is used cooperatively.
By setting, excavation can be saved and build sedimentation basin, and not have to be modified former flowing line, device is connect
Filtering function can be realized in the end of drainage pipeline networks.Different drainage requirements can be realized by the way that multiple drainage layers are arranged.This dress
It is simple and convenient to set installation, use environment multiplicity, turnover rate height.Both solved the drainage of foundation pit wasting of resources, mistake with a bellows
Filter tank setting is time-consuming and laborious, and purifier is difficult to the problem of having enough to meet the need.
Finally, it is to be noted that, herein, relational terms such as first and second and the like be used merely to by
One entity or operation are distinguished with another entity or operation, without necessarily requiring or implying these entities or operation
Between there are any actual relationship or orders.Moreover, the terms "include", "comprise" or its any other variant meaning
Covering non-exclusive inclusion, so that the process, method, article or equipment for including a series of elements not only includes that
A little elements, but also including other elements that are not explicitly listed, or further include for this process, method, article or
The intrinsic element of equipment.In the absence of more restrictions, the element limited by sentence "including a ...", is not arranged
