Description
Technical Field
The utility model relates to a building field, in particular to foundation ditch precipitation scrubbing device.
Background
In the foundation construction involving underground water, the precipitation of the foundation pit is one of the important links of the foundation pit construction, and whether the precipitation is successful or not directly affects not only the progress of the engineering, the construction cost and the quality of the supporting engineering, but also the safety of the engineering, so that sufficient attention must be paid. In the past, open drainage is mostly adopted for foundation pit dewatering, so that the ditches in a construction site are staggered, the construction road is muddy, and the production and life of the construction site are seriously influenced. Construction dewatering of deep foundations is common nowadays, and in order to improve construction efficiency and working environment of construction sites, pipelines are used for draining water in dark mode in each construction unit. The difficulty of the hidden drainage of the pipeline is that the sewage discharged by the submersible pump contains a large amount of mud and sand, so that the blockage of a drainage pipeline causes great inconvenience for construction, the construction speed is seriously influenced, a municipal drainage well is frequently blocked, and a municipal supervision department frequently causes the sewage drainage to stop on a construction site. The construction site also adopts the decontamination measure of building the grit chamber, but the cost is too high and the occupied area is too large. The product can completely solve the problems and save a great deal of labor, time and working hours.
Disclosure of Invention
The utility model aims to solve the technical problem that a foundation ditch precipitation scrubbing device is provided, simple structure, repeatedly usable need not to cut off the water when clearing up silt.
In order to achieve the above object, the utility model adopts the following technical scheme:
The utility model provides a foundation ditch precipitation scrubbing device, includes settling tank, box filter screen, inlet tube, knife gate valve, and the settling tank includes two fixed connection's uncovered box, and the lower part in the box is equipped with the box filter screen, is equipped with water inlet and delivery port on two relative sides of box respectively, and the settling tank outside is equipped with the inlet tube and is connected with the water inlet of two boxes respectively, and the water inlet inboard of two boxes sets up the knife gate valve respectively.
The water inlet pipe is horizontally arranged, and a water inlet pipe joint which is vertical to the horizontal pipe is arranged on a water inlet port of the water inlet pipe.
And a water outlet filter screen is arranged on the water outlet.
the box filter screen is detachably connected with the box body and is supported by a supporting plate fixedly connected to the box body.
Compared with the prior art, the beneficial effects of the utility model are that:
The utility model discloses simple structure, convenient operation, two boxes can carry out foundation ditch precipitation simultaneously and filter, and when needs clearance silt, but one side box of exclusive use filters, need not to cut off the water supply. The drain pipe of the submersible pump for pumping sewage in the foundation pit can be directly inserted into the vertically arranged water inlet pipe joint, so that the installation is convenient.
The utility model is used for precipitation in the building foundation excavation process is suitable for and filters silt, the gravel of getting rid of the groundwater.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a cross-sectional view of the present invention.
Fig. 3 is a side view of the present invention.
Fig. 4 is a schematic structural view of the settling tank.
In the figure: the device comprises a settling tank 1, a tank body filter screen 2, a water inlet pipe 3, a knife gate valve 4, a water inlet pipe joint 5, a supporting plate 6, a water outlet 7, a water inlet 8 and a water inlet filter screen 9.
Detailed Description
The following further describes the embodiments of the present invention with reference to the attached drawings:
As in fig. 1-4, a foundation pit precipitation scrubbing device, including setting tank 1, box filter screen 2, inlet tube 3, knife gate valve 4, the setting tank forms with the welding of the thick steel sheet of 3mm, the setting tank has a bottom uncovered, setting tank 1 includes two fixed connection's uncovered box, lower part in the box is equipped with box filter screen 2, box filter screen 2 is connected with the box dismantlement, box filter screen 2 is formed with the round steel welding of diameter 10mm around the frame, middle filter screen adopts the steel sheet net welding on the frame, steel sheet net aperture 20 x 20 mm. Which is supported by a support plate 6 fixedly attached to the cabinet. The support plate 6 is made of angle steel of 50mm multiplied by 50mm, has the length of 100mm and is welded on the inner side of the wall of the sedimentation tank.
The two opposite side surfaces of the box bodies are respectively provided with a water inlet 8 and a water outlet 7, the outside of the sedimentation box 1 is provided with a water inlet pipe 3 which is respectively connected with the water inlets 8 of the two box bodies, and the inner sides of the water inlets 8 of the two box bodies are respectively provided with a knife gate valve 4. A water gap filter screen 9 is arranged on the water outlet 7.
The water inlet pipe 8 is horizontally arranged, and a water inlet pipe joint 5 which is vertical to the horizontal pipe is arranged on the water inlet port of the water inlet pipe. The water outlet pipe of the submersible pump is inserted in the water inlet pipe joint 5.
When the device is used, the device is arranged along the vicinity of a foundation pit, and the arrangement distance is 25 m. The water outlet pipe of the submersible pump is connected with the inlet pipe and discharges water into the tank. When clearing up silt, utilize the knife gate valve to switch each other and use two boxes, do not influence drainage work, send the special messenger to regularly inspect the setting tank, when treating that incasement mud, sand deposit to box delivery port lower surface, take out the filter screen, with the mud, the sand clean up that deposit in the box. Then the filter screen is reset again, and the dirt separator can continue to work effectively. During inspection and cleaning, the big sand stones at the upper part of the filter screen of the box body are directly separated from the silt at the lower part.
In the practical application of the device, the underground foundation can be lowered for 40 days, the dark drainage pipeline works very smoothly, and the phenomenon of blockage is avoided. The municipal drainage well has no phenomenon of over-blockage. Because the construction precipitation is very smooth, the construction speed of the earth excavation is very high, and the smooth construction of the whole main body engineering is guaranteed.
The above is only the basic principle of the present invention, not to the present invention makes any limitation, all the bases of the present invention are the same changes and modifications to the above, all within the scope of the protection scheme of the present patent technology.
