Abstract

The utility model discloses a plugging structure of a high-rise building deep foundation pit large water volume tube well. The plugging structure comprises a dewatering tube well (1), wherein the dewatering tube well (1) is internally provided with a steel sleeve (2); and the plugging structure is characterized in that the inner side of the steel sleeve (2) is fixedly provided with an annular flange (3), the flange (3) is provided with a steel cover plate (4), and the flange (3) and the steel cover plate (4) are connected through a bolt (5). The plugging structure disclosed by the utility model has an extremely-wide application range, is suitable for the plugging of a deep foundation pit dewatering tube well under any conditions and is particularly suitable for later plugging of a high-rise building deep foundation pit dewatering tube well, not only can first construction of an engineering structure and the tube well plugging quality be ensured, but also the plugging structure cannot be affected by external factors such as the depth and the size of an underground foundation pit, the size of the tube well water inflow amount and the size of water pressure.

Description

Deep foundation pit of tall buildings big yield pipe well plugging structure
Technical field
The utility model relates to a kind of building big yield pipe well structure.
Background technology
Along with the fast development in builing industry and city, many highrise building buildings are rised sheer from level ground, and the projected depth of Underground Construction is also more and more darker.The different action modes of underground water and the big or small degree of water pressure, bring difficulty to Underground Construction, particularly difficulty of construction is larger under the bad operating mode of peripheral water stopping wall water sealing effect, and shutoff mode and the effect of precipitation pipe well in foundation ditch also proposed higher requirement.Shutoff for pipe well must be taked different measures according to different situations, can reach and neither affect the underground engineering structure concrete quality, again the effective purpose of shutoff pipe well.
Requirement heavy according to the structure anti-floating from foundation ditch and the large construction of bottom plates of basement stage, up to the main structure construction stage, all need keep the long-term continuity water-pumping/draining of precipitation pipe well.All pipe wells in foundation ditch all do not seal when the large construction of bottom plates of basement, steel sleeve is set directly passes large base plate.In the later stage, then according to the concrete condition of basement bottom board with the shutoff of precipitation pipe well.Shutoff to pipe well, usually adopt at present the Plate Welding sealing, and the ability welding under anhydrous state of welding procedure General Requirements, and when the welding of wet trade sealing steel plate, must be within the shortest time, with the sealing of steel plate full weld, in case the water burst speed that makes progress in pipe is greater than the speed of welding of sealing steel plate, steel plate just can not be constructed under wet trade, pipe well shutoff failure.
Summary of the invention
The purpose of this utility model is exactly for above-mentioned the deficiencies in the prior art, provide a kind of applied widely, save the deep foundation pit of tall buildings big yield pipe well plugging structure of material, no operatton time-constrain.
The technical solution adopted in the utility model is as follows:
A kind of deep foundation pit of tall buildings big yield pipe well plugging structure, it includes the precipitation pipe well, in the precipitation pipe well, steel sleeve is installed, and it is characterized in that the inboard of described steel sleeve is fixed with the flange plate of annular, steel deck-plate is installed on flange plate, and described flange plate is connected by bolt with steel deck-plate.
The outside of described steel sleeve is welded with seal ring.
The top of described steel deck-plate is provided with the sealing steel plate, and the surrounding of described sealing steel plate and the inwall of steel sleeve are welded and fixed, and is filled with expansive concrete between described steel deck-plate and sealing steel plate.
Described seal ring is provided with the up and down twice.
Between described steel deck-plate and flange plate, rubber seal is installed.
The beneficial effects of the utility model have:
The scope of application is extremely wide, is applicable to the shutoff of the foundation pit dewatering pipe well under any state, is specially adapted to the later stage shutoff of deep foundation pit of tall buildings precipitation pipe well.Can guarantee that engineering structures first constructs and pipe well shutoff quality, not be subjected to again the impact of the extraneous factors such as the depth of basement foundation ditch and size, pipe well water yield size, water pressure be big or small.Compare with the shutoff of band pump, the valve method for blocking of common employing, only need the processing of field by using steel plate, need not buy valve and accessory, submersible pump is recyclable to be re-used, and saves material.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation at the utility model flange plate place.
The specific embodiment
The utility model is further described below in conjunction with accompanying drawing:
As shown in Figure 1, it includes precipitation pipe well 1 the utility model, and steel sleeve 2 is installed in precipitation pipe well 1, and the inboard of steel sleeve 2 is fixed with the flange plate 3 of annular, and steel deck-plate 4 is installed on flange plate 3, and flange plate 3 is connected by bolt 5 with steel deck-plate 4.The diameter of steel deck-plate 4, take the weld seam of avoiding flange plate 3 peripheries as control, generally than the flange plate 3 little 40-50mm of external diameter.Along periphery, the M8 bolt hole corresponding with bolt 5 on flange plate 3 is set.
The outside of described steel sleeve 2 is welded with up and down twice seal ring 6, and the upper and lower opening of seal ring 6 respectively with pipe well steel sleeve full weld, guarantees that weld seam is tight, water-tight.Check that steel sleeve 2 and seal ring 6 itself have the defectives such as non-corroding, sand holes, hole, guarantee the sealing of steel sleeve and seal ring itself.
The top of described steel deck-plate 4 is provided with sealing steel plate 7, and it is after the water shutoff of flange method, another road waterproof safeguard measure, and diameter is identical with flange plate 3 external diameters.The inwall of the surrounding of described sealing steel plate 7 and steel sleeve 2 is welded and fixed, and is filled with expansive concrete 8 between described steel deck-plate 4 and sealing steel plate 7.Between steel deck-plate 4 and flange plate 3, rubber seal 9 is installed, uses AB glue that rubber seal is pasted on steel deck-plate 4, be convenient to the installation exercise under pipe well water burst state.
Other undeclared part that the utility model relates to is same as the prior art.
