Description
Technical field:
The utility model relates to building engineering field, particularly relates to a kind of for basement construction water plug.
Background technology:
Underground construction must first to needing the sub-surface excavated to draw water operation in work progress, get rid of and wait to excavate the moisture content in region in the earthwork, make to be excavated the earthwork and be in relatively dry state, just be convenient to excavate smoothly the earthwork, still need to continue to carry out drawing water operation to desired depth even if excavate, make the static water level in underground be in below construction earth's surface comparatively low water stage, just can carry out casting and solidifying of concrete floor, prevent that groundwater table is too high causes extruding, destruction to base plate.In existing construction operation, several draining deep-wells must be got in compartment of terrain in region to be excavated, form gang of wells, difference installing submersible pump in every mouthful of deep-well, uninterruptedly synchronously draw water, thus control the static water level in underground, guarantee the relatively dry of the following soil property in region to be excavated, prevent from occurring landslide in work progress, cause casualties, increase difficulty of construction.The submersible pump quantity that this traditional underground water pump drainage mode not only needs is many, supply line, row pipeline consumption is large, erection trouble, and to ensure all submersible pumps have want ceaselessly operate continuously, when after the water level decreasing in well to certain depth, submersible pump will proceed to non-full load operating conditions until dehydration idle running, until in well water level because of infiltration go up time water pump just can reenter aspiration phases, the so not only at substantial energy, and the application life of submersible pump can be reduced, increase construction input cost.
Utility model content:
For realizing the high efficiency synchronous pump drainage to gang of wells, reduce the usage quantity of submersible pump, simplify the erection of electric wire arrangement and discharge pipe line, improve the efficiency of drawing water of submersible pump, reduce the energy consumption of the synchronous pump drainage of deep foundation ditch pipe well, the utility model provides the synchronous pump drainage dewatering device of pump many well depths foundation ditch pipe well.
The utility model realizes by following technical scheme.
The synchronous pump drainage dewatering device of one pump many well depths foundation ditch pipe well, comprise submersible pump and drinking-water pipe, submersible pump is arranged on the bottom of drinking-water pipe, it is characterized in that: the combination of submersible pump and drinking-water pipe is placed in main shaft A, connect water dispenser in the upper end of drinking-water pipe, going out on water dispenser to be provided with total delivery port, formed in siphon condition in the pipeline of pipe and be provided with valve, one end that siphon condition forms pipe with go out water dispenser and interlink, the other end and the collecting container of siphon condition formation pipe are tightly connected, auxiliary shaft intake pipe is connected with collecting container, auxiliary shaft intake pipe stretches in auxiliary shaft, one way valve is connected in the bottom of auxiliary shaft intake pipe, one way valve by direction for can only fetch water from auxiliary shaft, can not to auxiliary shaft draining, siphon outlet pipe one end is connected with collecting container, the siphon outlet pipe other end stretches in main shaft A, the bottom stretching into main shaft part at siphon outlet pipe is provided with water shutoff parts.
Further, filtering screen is provided with in the suction side of one way valve.
Further, the setting position of water shutoff parts is higher than the position of one way valve in auxiliary shaft.
Further, water shutoff parts are U-shaped body.
Further, water shutoff parts are S shape body.
Further, valve is manual ball valve.
Further, it is the flat body of anti-suction that described drinking-water pipe, siphon condition form pipe, auxiliary shaft intake pipe and siphon outlet pipe.
The course of work of the present utility model is as follows:
Start submersible pump to start to draw water, water in main shaft is through submersible pump, drinking-water pipe is discharged from going out water dispenser, water level in main shaft will reduce gradually, opening valve makes siphon condition formation pipe be in unimpeded state, the water extracted out from main shaft is through going out water dispenser, siphon condition is formed in pipe input set water receptacle, owing to being provided with one way valve in the bottom of auxiliary shaft intake pipe, therefore in collecting container water flow into and just can discharge in the process of filling auxiliary shaft intake pipe and siphon outlet pipe its manage in air, valve-off after auxiliary shaft intake pipe and siphon outlet pipe fill water, now owing to there is water-head between main shaft and auxiliary shaft, and be full of water between the auxiliary shaft intake pipe connected between two wells and siphon outlet pipe, namely between main shaft and auxiliary shaft, siphon passage is defined, the trend that the water surface elevation oriented main shaft A water surface elevation of auxiliary shaft is close, draining in main shaft A and auxiliary shaft is finally all completed by the submersible pump be placed in main shaft A, because siphon outlet pipe body is provided with water shutoff parts at main shaft member base end, because water shutoff parts are provided with elbow seal water structure in short transverse, even if the position that main shaft water level drops to submersible pump also can maintain the full of water between auxiliary shaft intake pipe and siphon outlet pipe, also the condition producing siphonage is just maintained.When the of short duration appearance of siphon condition was lost efficacy, if open valve again moisturizing just can recover siphon condition, then valve-off.The utility model can make the water in auxiliary shaft continue to flow in main shaft, just can synchronously be aspirated main shaft and auxiliary shaft at full capacity continuously by a submersible pump, the efficiency of drawing water of submersible pump can be improved, significantly reduce the power consumption that group wells aspirates separately, and the Meteorological of submersible pump and electric wire is minimum, the application life of submersible pump is guaranteed, there will not be because of no-water dry combustion phenomenon.As long as ensure that submersible pump continuous pumpage just can make the water surface elevation of major-minor well maintain the predetermined height of people, guarantee that the soil layer of the following desired depth in earth's surface maintains relatively dry state, be convenient to excavation of earthwork operation carry out smoothly, after completing excavation, because draw water, operation is continuing to carry out, although the degree of depth of well body reduces, in well body, water level is still in the predetermined height of people, so the base plate of just having cast, before solidifying, also can not stand the extruding of water and be destroyed original structure.
Apply operating principle of the present utility model, in gang of wells, between other auxiliary shaft and main shaft, all adopt syndeton of the present utility model, with a submersible pump, all gang of wells are synchronously drawn water with regard to realizing like this.Thus realize the purpose of this utility model.
