Concrete meaning in the present invention.
As shown in fig.1, for the building underground water drop row of the embodiment of the present invention and reuse method flow chart, it is included such as
Lower step：Embedded catch pit：Planned according to the well of predeterminated position and bury catch pit；Lay drainage pipeline：According to default
Path carries out drainage pipeline laying；Water level control：Set in the well to control the water level control system of water level in well
System；Purification recycles：Recycled after the water sedimentation that the water level control system is discharged is purified.
Specifically, before burying catch pit, the position planning of well is first carried out, and is beaten according to well planning chart
Well.During well-digging, according to building level of ground water and the situation of soil property, determine spacing between well and well, well it is straight
Depth of footpath and well etc..After well is accomplished fluently, prefabricated pipe of concrete is put into wellhole, and sandstone mistake is laid with shaft bottom
Filtering layer.Then plan catch pit burial place further according to the position of well, and select suitable catch pit to be buried, in order to
Collection to precipitation.It should be noted that catch pit can select the PVC catch pits of finished product, can also be during construction
Carry out concreting.
In the present embodiment, with building level of ground water throughout the year in -2m or so, rich groundwater, soil permeability coefficient compared with
Greatly, building foundation is dug exemplified by deep -5m, and well spacing is 30m, a diameter of 400mm of well, well depth are -20m；Often saved in wellhole prefabricated mixed
The length of solidifying soil pipe is 1m, and a diameter of 300mm, the sandstone filter layer in shaft bottom is 30cm；Catch pit using PVC material make and
Into being divided into two kinds of A and B, wall thickness is 10mm, and the length, width and height of wherein catch pit A are respectively 700mm, 700mm and 1000mm；Collection
Puddle B length, width and height are respectively 1000mm, 1000mm and 1200mm.Catch pit A is connected with well, easy to by catch pit B
Water imports, and catch pit B is arranged on trunk roads, is on the one hand flowed into easy to water excessive in catch pit, and the opposing party can converge water
Enter settling tank.
Specifically, if drainage pipeline, the laying of drainage pipeline is determined according to the entrance of building and municipal drainage pipe network
Path, and according to the laying of the suitable drainage pipeline of path progress, drainage pipeline is together in series with catch pit, make catch pit
In water can be flowed by pipeline stream.Meanwhile when drainpipe is laid, pipeline is set to keep certain continuous slope
Degree, to ensure the circulation of water in pipe.It is understood that drainage pipeline is used as connection catch pit with well or catch pit with catchmenting
Interface channel between hole, can either import the water being imported into catch pit in well, and can ensure will be more in catch pit
Remaining ponding is flowed into adjacent catch pit, to ensure the water balance in whole system.
In the present embodiment, the drainpipe selected according to displacement is divided into supervisor and branch pipe, wherein supervisor uses diameter
The bellows of 300mm, is arranged on trunk roads, that is, is arranged between catch pit B and catch pit B, settling tank, and effective guarantee can
To pass through enough water；Branch pipe is managed using diameter 110mmPVC, is arranged between catch pit A and catch pit A, well, for current
It is dynamic.Meanwhile the sustained grade between pipeline is 1%, to ensure that water can continuously flow.It is understood that by being managed in laying
Pipeline is set to certain gradient during road, is conducive to water and is flowed in pipe, and successfully import catch pit.
Specifically, water level control, is put into an immersible pump in every mouthful of well saliva well, and every immersible pump sets a power supply control
Case processed, has switch, earth leakage protective device, water level control relay in case.Water level reaches setting relay at water pump upper surface in well
Device lower limit control point, relay control switch, which automatically powers off, when water level reaches this stops pumping.Water level, which reaches, in well sets
Place sets relay upper limit control point below the bottom absolute altitude of meter hole, and when water level reaches this, relay control switch, which is powered, to be started
Draw water, until water level is dropped in the range of bound.It is understood that the extreme position up and down of water level can be set according to actual conditions
Put, as long as being able to ensure that dewatering effect reaches design requirement.
In the present embodiment, water level reaches setting relay lower limit control point, water at the 0.5m of water pump upper surface in well
Relay control switch, which automatically powers off, when position reaches this stops pumping；Water level reaches below the bottom absolute altitude of design hole at 3m in well
Relay upper limit control point is set, and when water level reaches this, relay control switch, which is powered, to be started to draw water.
Specifically, purification recycles, and builds a second-level settling pond in the venue first, precipitation and passes through water level control system
The water of system discharge, imports in sedimentation basin after two-stage precipitation is handled by drainpipe, after reaching discharge and recycling standard, leads to
It is overpressurized water pump and pipeline is respectively used to scene greening spray, airborne dust flushing, construction water etc. and is recycled.It is appreciated that
It is that control valve can be set on pipeline, to carry out the control of water size and switch；Relay control is provided with pressure pump
Water level elevation processed, water level automatically power off when being less than water pump.
In the present embodiment, sedimentation basin be a length and width, it is deep be respectively that the two level of 6000mm, 4000mm and 3000mm is sunk
Shallow lake pond, side wall are brick setting 240mm thickness walls, and inner wall is plastered.Hole bottom is 100mm thickness C15 concrete cushions.
Obviously can draw, building underground water drop row provided by the invention and reuse method, are catchmented by embedded
Hole, and it is connected by drainpipe with the well planned and accomplished fluently in advance, effectively realize the collection to natural precipitation.
Especially, building underground water of the invention drop row and reuse method, by setting water level control system in well
System, when water level exceedes pre-set height of water level in well, level relay switch power control diving pump drainage；When in well
When water level is less than pre-set height of water level, level relay switch circuit breaking control immersible pump stops draining, effective to realize
Control to height of water level in well.
Further, the present invention purifies reutilization system by setting, by what is discharged in well by water level control system
Water carries out two-stage precipitation purified treatment, is reused after reaching discharge and recycling standard, has effectively saved water
Resource, achievees the purpose that water-saving.
Obviously, various changes and modifications can be made to the invention without departing from essence of the invention by those skilled in the art
God and scope.In this way, if these modifications and changes of the present invention belongs to the scope of the claims in the present invention and its equivalent technologies
Within, then the present invention is also intended to comprising including these modification and variations.
