Description
Technical field
The utility model belongs to the protective device of construction industry geotechnical engineering profession underground water control system, for mentioning
Keep-alive rate of the high dewatering well in complicated construction environment.
Background technique:
Base pit dewatering uses sandpipe, concrete pipe, steel pipe in urban construction, is distributed in foundation pit planar range, in use often
It is dug and is transported by the earthwork, reasons damage inactivation, the damage rate such as well head soil layer extruding are drastically influenced in 20%-40%, even up to 70%
Base pit dewatering effect and construction period.
Summary of the invention
In order to solve water level control monitoring, the damaged keep-alive of dewatering well during pit earthwork is had bad luck, guarantee dewatering well
Maintenance safety, the utility model provide a kind of dewatering well protective device for foundation pit construction.
A kind of dewatering well protective device for foundation pit construction, it is characterized in that including protective case, protective case two sides are equipped with and hang
Ear by hinge and latches bolt and connects left top cover, right top cover above protective case, and left top cover, right top cover are equipped with fluorescence labelling
Band, right top cover are equipped with indicator light.Left top cover, right top cover fasten to form spherical crown；
Semicircular indentations are equipped at the top of the left top cover, right top cover, two semicircular indentations are combined to form a circle
Hole, water pump connect water pipe, and water pipe passes through circular hole, and indicator light connects pump power.
Indicator light shows water pump operation state.
The internal diameter of the protective case is 550mm, and length is 600mm.
The diameter of the spherical crown is 550mm, and height is 286mm.
Utility model works principle:
The utility model is placed in dewatering well top, water pump, water pipe, electric wire are respectively by staying slot to complete in place, Ji Kezheng
It is often used.Water level ascending water pump startup, indicator light extinguish, and water pump exception or water level reach predetermined absolute altitude, and indicator light lights.
Top cover can effectively prevent soil block, sundries, personnel etc. and fall into precipitation wellhole, lead to scrap even dried-up well.Protective case
It can prevent earth-working vehicles from squeezing the dewatering well periphery soil body, tube wall rupture is caused to bury water pump.
The utility model is light simple, structurally reasonable, quick for installation, can be recycled and reuses, can be used for all foundation pits
The construction and maintenance of supporting precipitation system.
Detailed description of the invention
Fig. 1 is the structure chart of the utility model.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is the right view of Fig. 1.
In figure, 1, circular hole, 2, indicator light, 3, right top cover, 4, lock bolt, 5, lifting lug, 6, left top cover, 7, fluorescence labelling
Band, 8, sandpipe, 9, protective case.
Specific embodiment
Shown in Fig. 1, Fig. 2, Fig. 3, a kind of dewatering well protective device for foundation pit construction, including protective case 9, protective case 9
Two sides are equipped with lifting lug 5, and left top cover 6, right top cover 3 are connected by hinge behind protective case 9, passes through lock bolt 4 behind protective case 9
Left top cover 6, right top cover 3 are connected, left top cover 6, right top cover 3 are equipped with fluorescence labelling band 7, and right top cover 3 is equipped with indicator light 2.Left top
It is 550mm that lid 6, the fastening of right top cover 3, which form diameter, and height is the spherical crown of 286mm；
Semicircular indentations are equipped at the top of the left top cover 6, right top cover 3, two semicircular indentations are combined to form one
Circular hole 1, water pump connect water pipe, and water pipe passes through circular hole, and indicator light connects pump power.
Indicator light shows water pump operation state.
The protective case 9 is that internal diameter is 550mm, and length is the pipe of 600mm.
Dewatering well Cheng Jinghou, one group of 2 worker carry lifting lug, and the utility model alignment dewatering well is in place, water pump, water
Pipe, electric wire are respectively by staying slot to arrange in place, and can be powered normal use.
It installs rear left and right top cover to close, prevents soil block, sundries, personnel etc. from falling into precipitation wellhole, water level ascending water
Pump startup, indicator light extinguish, and water pump exception or water level reach predetermined absolute altitude, and indicator light lights.
When progress earth excavation is cleared, bolt locking is latched, even carrying on construction work at night, protective case and top cover can prevent the earthwork
Vehicle rolls the dewatering well periphery soil body, and tube wall rupture is caused to bury water pump.
Fluorescent reflection item can effectively prevent earthmoving machinery and bury well location, and the mechanical earthwork is dug after the completion of fortune, manual cleaning precipitation
Well side loosens the earthwork, and left and right top cover is opened, and clears up around borehole wall from coil to coil, and the utility model can decline therewith, improves water pump
Construction rate when decentralization again is proposed outside.
