Embodiment
The method that dewatering device is installed and blocked in processing foundation ditch in order to further appreciate that the present invention, below by way of implementation
Example, and coordinate accompanying drawing to be described as follows in detail to technical scheme and its advantage.
The method of installation and the closure of dewatering device, comprises the following steps in the processing foundation ditch of the present invention：
As shown in figure 1, manufacture aquifer 5；
Aquifer 5 is made up of the rubble of unified size, and rubble size is 40mm, and macome-scale is necessarily more than the honeycomb of steel pipe
Shape hole 10, is uniformly layered in the square heatable adobe sleeping platform that the underground length of side is 1200mm (rigid waterproof sleeve is embedded in underground together),
Its reclaimed water can rapidly be collected, and can effectively prevent debris from entering in water collector, it is to avoid suction pump 6 is pumped into debris and damaged
It is bad.
Water collector is embedded to aquifer 5；Water pump 6 is set inside water collector；
As shown in Figure 1, 2, water collector includes steel pipe 1, rigid waterproofing wing ring 2 and cellular hole 10, rigid waterproofing wing ring 2
It is welded on the outside of steel pipe 1, steel pipe 1 and is provided with cellular hole 10, water pump 6 is placed in the inside of steel pipe 1.The water collector can have
Effect prevents water from outer wall of steel pipe leak.Steel pipe 1 is preferably DN300mm.In one embodiment, away from the mouth of pipe 1250mm of steel pipe 1
Place's welding rigid waterproofing wing ring 2.In one embodiment, the thickness of rigid waterproofing wing ring 2 is 8mm, and interior diameter is 326mm.
In the upper end winding rubber and plastic heat-preservation cotton 4 of steel pipe 1, then tighten with tape winding；
When making foundation ditch template, 300mm winds rubber and plastic heat-preservation cotton 4 under template to template, makes after the winding of rubber and plastic heat-preservation cotton 4
Thickness reach 200mm, highly reach 300mm, then tighten with tape winding, thus, plugging device be installed in the later stage, no
Excavated by manual work is needed to dig, it is ensured that the stability attractive in appearance and foundation pit structure during installation.
Form the concrete 3 around water collector and rubber and plastic heat-preservation cotton 4；
Remove rubber and plastic heat-preservation cotton 4；
Form plugging device；
As shown in figure 3, wherein, plugging device includes ring flange 7, rubber blanket 9, blank flange 8 and bolt 11, blank flange
8 are located at the top of ring flange 7, and rubber blanket 9 is placed between ring flange 7 and blank flange 8, the surrounding of ring flange 7 and blank flange 8
Bolt hole is provided with, ring flange 7 and blank flange 8 are connected by the bolt 11 through bolt hole, and ring flange 7 is welded on steel pipe
On 1.Ring flange 7 can be DN300mm.The bearing capacity of the plugging device is strong, effectively can block water seal, prevent leak；
Pour after solidifying soil, durability is strong, increase service life.
Finally, with the formation sump of concrete 3, as shown in Figure 4.
The foundation ditch of the sump is integrally rationally divided into some regions, while carrying out precipitation.
The present invention advantageous effects be：Compared with conventional precipitation steel pipe built-in process, steel is used conventional precipitation more
Pipe punching is directly embedded to underground, and the present invention is that browser at the bottom of the catchment steel pipe uniformly breaks into cellular hole 2mm, is embedded to aquifer 5, stores
Water layer 5 is the stone that size is 40mm, and diameter is more than honeycomb structure hole dia, it is ensured that water smoothly flows into water collector, prevents miscellaneous again
Thing enters；Compared with conventional precipitation steel pipe built-in process, during conventional embedded steel tube, steel pipe all fills dead with concrete under template,
Present invention 300mm under template to template, winding rubber and plastic heat-preservation cotton 4, the thickness after reaches 200mm, highly reaches 300mm,
Winding is tightened with tape again, excavated by manual work chisel is not needed during such later stage closure, was not both affected the appearance, and do not influence mechanism；
Compared with the method for blocking of conventional sump, conventional closure directly fills dead with concrete or is welded with iron plate, present invention design
There is special plugging device, plugging device, can after tightening by ring flange 7, rubber blanket 9 and blank flange 8 are constituted, bolt 11 is constituted
So that effectively water seal to be blocked；Compared with conventional precipitation Steel Pipe Design, conventional precipitation steel pipe does not have any measures of preventing water, this hair
It is bright that the anti-hydrofoil ring of a rigidity is welded at steel pipe 1250mm, paste SBS waterproof rolls when pre-buried at the anti-hydrofoil ring of rigidity again,
Effectively suppress underground water from outer tube wall seepage.
Above-described embodiment is only intended to clearly illustrate example of the present invention, and not limitation of the invention.It is right
For those skilled in the art, can also be made on the basis of above-described embodiment it is other it is various forms of combination, change or
Modification, protection scope of the present invention is defined by claim.
