Description
Technical field
The invention belongs to building foundation pit dewatering installation field, particularly a kind of drainage of foundation pit locking device.
Background technology
Usually when carrying out draining to building site foundation ditch, adopt the water discharge method that some are traditional, the bright row's method of such as foundation ditch, but stand in great numbers due to building around present many building sites, limit the dig on a wide area of foundation ditch.
As reverse construction adopts digging mode from top to bottom, even if Seal treatment has been done in foundation ditch surrounding and substrate, but being excavated to foundation plane place still has underground water to ooze out unavoidably, even produce water burst phenomenon, how the underground water discharge in foundation ditch is not affected concrete the building of baseplate reinforcing bar and just become insoluble problem.
So this drainage of foundation pit locking device is the building site of dig on a wide area foundation ditch and the building site of conventional excavation to provide convenience.
Summary of the invention
The object of this invention is to provide a kind of drainage of foundation pit locking device, this device can make convenient discharge of the ponding in building foundation pit and not affect building of underplate concrete, and structure is simple, and result of use is good.
The technical scheme adopted is:
A kind of drainage of foundation pit locking device, comprises steel cylinder, dredge pump, gutter and well lid.
Its technical essential exists:
Be provided with dredge pump in steel cylinder, dredge pump is connected with gutter.
Steel cylinder inwall is fixed with many brace rods.Many brace rod is provided with the well lid offering centre bore.
Gutter is through the centre bore of well lid.
Valve installed by gutter, and valve is positioned at above well lid.
Described steel cylinder is the steel cylinder of upper and lower opening, and offers multiple water seepage hole in barrel circumference.
Evenly between the inwall and gutter of described steel cylinder be provided with many reinforcing ribs, many reinforcing ribs are positioned at above well lid.
Described valve is ball check.
The waterproof power line of dredge pump passes well lid along gutter outer wall.Power supply and the control device of dredge pump are positioned at ground, and this is known technology, therefore not repeated description.
Using method of the present invention:
First the steel cylinder of upper and lower opening is placed on request the plash place needing draining, uses as draining collecting well, remove the foreign material in steel cylinder and the height adjusting steel cylinder to correct position, dredge pump is placed on bottom steel cylinder.Start dredge pump, while ponding is discharged, baseplate reinforcing bar welds with steel cylinder outer wall, the concreting of steel cylinder Outer Bottom Plating is completed.
The concreting of steel cylinder Outer Bottom Plating completes and reaches design strength requirement, then closes this device according to the following steps.
The first, continue to start dredge pump, discharge collecting well internal water accumulation, by well lid in steel cylinder and steel cylinder inwall and draining steel-pipe welding, then build fist stage concrete above well lid (concrete employing is mixed with the early-strong-fast-hard concrete of outer dose), after tens minutes, fist stage concrete intensity reaches designing requirement.
The second, for increasing baseplate reinforcing bar concrete strength, above spherical shape back stop valve, many reinforcing ribs (bar diameter and former baseplate reinforcing bar consistent size) are adopted to be welded in steel cylinder.According to the water burst situation of steel cylinder collecting well, can the startup dredge pump of not timing water be discharged.
Three, after reinforcing rib has welded, close spherical shape back stop valve, block waterproof power line, remove the top hose on draining steel pipe, continue concreting (concrete adopts the early-strong-fast-hard concrete being mixed with outer dose), evenly vibrate, until the concrete in steel cylinder is mutually concordant with the concrete of steel cylinder Outer Bottom Plating.
The concrete used is the concrete (this is known product) of Mixed With Admixture.
To first estimate that underground water carrys out the water yield when using this device, to ensure below the water emptying that reaches in foundation ditch or the elevation being discharged to restriction.This device can be laid flexibly at same foundation ditch, adopt two or more dewatering installation conjunctive use.Finally do not take out dredge pump, but by below it Transducers Embedded in Concrete.The model of dredge pump and lift are determined according to displacement and are selected.
Its advantage is:
This device can discharge the ponding in the foundation ditch of building site easily, can lay this device flexibly at same foundation ditch, two or more dewatering installation conjunctive use, this dewatering installation structure is simple, result of use is good, reduces traditional drainage of foundation pit construction costs and effluent cost greatly.
Accompanying drawing explanation
Fig. 1 is the structural representation of this device.
