Description of the drawings
Structural representations of the Fig. 1 for this utility model base pit dewatering system.
Specific embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Refering to Fig. 1, it is shown that the structural representation of this utility model base pit dewatering system.As shown in figure 1, this utility model
Base pit dewatering system includes：Suction hose 30, water-supply-pipe 31 and water pump, wherein suction hose 30 have suction side 300 and outfan
301, suction side 300 is embedded in the permeable layer 1 of bottom of foundation ditch, and suction side 300 is provided with suction hole, and suction side is coated with permeable guarantor
Sheath, permeable protective layer are covered in suction hole.Water-supply-pipe 31 is communicated in outfan 301, and water pump is located at suction hose 30.So as to this reality
The root infiltration of the bed course stock mould that bottom of foundation ditch occurs that can solve to excavate with new base pit dewatering system so that coiled material is heaved and altered
The problem of water.The simple structure of this utility model base pit dewatering system, easy to operate, using effect is good.
As shown in figure 1, in the present embodiment, after excavation pit, permeable layer 1 is located at the bottom of foundation ditch, on 1 upper berth of permeable layer
If Waterproof structural course 2.Laid with side slope graded broken stone in the bottom of foundation ditch, form permeable layer 1, so as to seeping water occurs in bottom of foundation ditch
When, as permeable layer 1 is formed using rubble laying, thickness is 70mm to 80mm, and the water for oozing out mixes in the rubble of permeable layer 1
In.At this moment, if not taking any measure, then it is more and more that the water for oozing out will be built up, may finally ooze being layed in
Waterproof structural course 2 on water layer 1 is heaved, in addition destruction Waterproof structural course 2 and produce channeling water problem, affect construction quality and
The efficiency of construction, so in order to the infiltration for producing bottom of foundation ditch is transported to outside foundation ditch, using this utility model base pit dewatering
System carries out water suction process.
Suction side 300 and outfan 301 are respectively arranged on the two ends of suction hose 30, and suction side 300 is embedded in permeable layer 1,
The water that suction side 300 is oozed out in being used to build up permeable layer 1.Specifically, suction side 300 is provided with suction hole, and suction side 300 is coated with
Permeable protective layer, permeable protective layer are covered in suction hole, and permeable protective layer plays a part of to filter sandstone, prevents the debris such as sandstone
Blocking suction hole, causes to damage.
In the present embodiment, suction side 300 is communicated with transverse tube, and specifically, suction side 300 is communicated in the pars intermedia of transverse tube
Position, so as to form T-type structure.The closed at both ends of transverse tube, prevents sandstone from entering in suction hose from the two ends of transverse tube, causes suction hose
Blocking.Transverse tube is the one section of copper sheet pipe for intercepting, and the two ends welding copper sheet of copper sheet pipe is closed.Offer on transverse tube many
Individual suction hole, and at suction hole, it is coated with permeable protective layer.The surface of suction side 300 sets multiple suction holes, the water in permeable layer 1
Can enter in suction hose 30 through the suction hole on transverse tube and suction side 300.In the present embodiment, suction is communicated in using transverse tube
Water end (W.E.) 300 forms T-type structure, so as to increase the contact area with sandstone in permeable layer 1, such that it is able to arrange more water suctions
Hole, increases the efficiency of water suction.
In the present embodiment, to prevent the hole plug that absorbs water, with permeable grid cloth as permeable protective layer, by permeable grid cloth
It is coated on suction side 300 so that permeable grid cloth covers suction hole.Permeable grid cloth plays a part of filtration, by rubble etc.
Impurity gets lodged in the outside of permeable grid cloth, only allows water to enter into from suction hole in suction side 300.Permeable grid is deployed troops on garrison duty
Sandstone in water layer 1 is clogging by suction hole, damages this utility model base pit dewatering system, increased this utility model foundation ditch drop
The service life of water system, has saved resource, but has been not limited thereto, and permeable protective layer can also be other drainage screens, energy
Water into suction hose 30 is filtered.
Transverse tube is arranged on behind suction side 300, suction hose 30 is vertically plugged in permeable layer 1 so that 300 He of suction side
Transverse tube is embedded in permeable layer 1, and outfan 301 exposes outside permeable layer 1, then water-supply-pipe 31 is communicated in the outfan of suction hose 30
301, water-supply-pipe 31 is for the water built up in suction hose 30 is transported to outside foundation ditch.
In the present embodiment, water-supply-pipe 31 uses flexible pipe, depending on the length of flexible pipe can be according to practical situation.Due to
Foundation ditch is located at below earth's surface, and physical features is relatively low, needs water pump to be extracted, i.e., using being arranged at the water pump of water-supply-pipe 31 to permeable layer
1 draws water.
Current are controlled for convenience, are provided with switch 32 in the connectivity part of suction hose 30 and water-supply-pipe 31.When switch 32 is opened,
Work of drawing water can be carried out, when switch 32 cuts out, control water flows out, and can facilitate the construction of follow-up casting concrete.
Screed-coat 4 is laid on permeable layer 1, screed-coat 4 is poured using cement mortar and formed.After permeable layer 1 levelling,
4 upper berth of screed-coat sets Waterproof structural course 2.Specifically, Waterproof structural course 2 includes：Waterproof layer 20 and it is layed on waterproof layer 20
Fish tail and waterproof layer 21.Waterproof structural course 2 is prevented from the current on foundation ditch top and enters into bottom of foundation ditch, the effect with waterproof
Really.
As suction hose 30 is plugged in permeable layer 1, between suction hose 30 and permeable layer 1, there is gap, be to ensure waterproof effect
Really, this gap plugging is lived using waterproof roll.Specifically, waterproof roll is layed in into the waterproofing protection around hydrating structure 3
On layer 21, waterproof roll is coated on suction hose 30, and specifically, waterproof roll upwardly extends setting along suction hose 30, and is sticked
It is fixed on suction hose 30.
This utility model base pit dewatering system has the beneficial effect that：
This utility model base pit dewatering system by the permeable layer of bottom of foundation ditch bury suction hose, with water pump and water suction
Water in permeable layer is suctioned out by pipe, and water is transferred out foundation ditch by water-supply-pipe, and the bottom of foundation ditch for solving to excavate with this occurs
Bed course stock mould root infiltration so that coiled material heaves the problem of channeling water.The simple structure of this utility model base pit dewatering system,
Easy to operate, using effect is good.
This utility model is described in detail above in association with accompanying drawing embodiment, those skilled in the art can root
Many variations example is made to this utility model according to described above.Thus, some of embodiment details should not be constituted to this practicality
