Description
Technical field
The utility model relates to a kind of plugging dewatering well device, is mainly used in that groundwater table is higher, the plugging dewatering well shutoff to dewatering well comparatively at need, belongs to technical field of building construction.
Background technology
Foundation pit dewatering requisite one link during as Construction of Deep Excavation Engineering, construction success or failure for deep-foundation pit engineering are most important, conventionally according to using function to be divided into pressure-bearing dewatering well and drainage dewatering well, dewatering well completes and meets anti-floating in major project and requires rear enclosed.
According to engineering construction experience, when groundwater table is higher, particularly there is artesian water to do the used time, the shutoff of dewatering well is difficulty comparatively, according to conventional shut-in well order, its difficulty of construction of dewatering well of last shutoff is larger, under some special geologic conditions, the dewatering well of last shutoff cannot complete shutoff operation according to conventional method, and has percolating water hidden danger.
Utility model content
Utility model object: the purpose of this utility model is for the deficiencies in the prior art, a kind of plugging dewatering well device is provided, improved the shutoff efficiency of dewatering well, reduced the shutoff difficulty of dewatering well, reducing because plugging dewatering well is unsuccessful is the hidden danger of leaking that subsequently surface construction brings.
Technical scheme: a kind of plugging dewatering well device described in the utility model, comprise sealing ring flat-plate, steel sleeve, clip and cast iron blind plate, the external diameter of described sealing ring flat-plate is less than the internal diameter for the treatment of shutoff dewatering well, described seal ring sleeve-board is contained on the outer wall of steel sleeve, between the inwall of described sealing ring flat-plate and the outer wall of steel sleeve, be tightly connected, described cast iron blind plate can seal on the port that is fixed on steel sleeve by clip.
Further improve technique scheme: between described clip and steel sleeve port, be lined with sealing ring.
As preferably: the external diameter of described sealing ring flat-plate is less than the internal diameter 1-3mm that treats shutoff dewatering well.
Further: the internal diameter of described sealing ring flat-plate equates with the external diameter of steel sleeve.
Described sealing ring flat-plate adopts the thick steel plate of 10mm to be made.
The external diameter of described steel sleeve is 100mm.
Compared with prior art, its beneficial effect is the utility model: plugging dewatering well device described in the utility model (1) can be used for that groundwater table is higher, the plugging dewatering well shutoff to dewatering well comparatively at need; (2) improved the shutoff efficiency of dewatering well, reduced the shutoff difficulty of dewatering well, reducing because plugging dewatering well is unsuccessful is the hidden danger of leaking that subsequently surface construction brings.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, cast iron blind plate; 2, clip; 3, sealing ring; 4, dewatering well sidewall; 5, steel sleeve; 6, sealing ring flat-plate.
The specific embodiment
Below technical solutions of the utility model are elaborated, but protection domain of the present utility model is not limited to described embodiment.
Embodiment 1: as shown in Figure 1, a kind of plugging dewatering well device, comprises sealing ring flat-plate 6, steel sleeve 5, clip 2 and cast iron blind plate 1; Described sealing ring flat-plate 6 adopts the thick steel plate of 10mm to be made, and the external diameter of described steel sleeve 5 is 100mm.
The external diameter of described sealing ring flat-plate 6 is less than the internal diameter 2mm that treats shutoff dewatering well, the internal diameter of described sealing ring flat-plate 6 equates with the external diameter of steel sleeve 5, described sealing ring flat-plate 6 is sleeved on the outer wall of steel sleeve 5, between the outer wall of the inwall of described sealing ring flat-plate 6 and steel sleeve 5, seal welding is connected, described cast iron blind plate 1 can be fixed on the port of steel sleeve 5 by clip 2 sealings, between described clip 2 and steel sleeve 5 ports, is lined with sealing ring 3.
The concrete construction method that adopts above-mentioned plugging device to carry out shutoff to dewatering well is:
(1) sealing ring flat-plate is welded in and on steel sleeve, forms an integral body;
(2) steel sleeve, through gutter and cable, is placed on pithead position;
(3) backfill cotton-wool, graded sand and stone respectively in dewatering well, then backfill C30 concrete is to sealing ring flat-plate design height on steel sleeve;
(4) transfer steel sleeve, steel sleeve top is lower than basement bottom board structural plane 100mm, and by sealing ring flat-plate and dewatering well sidewall full weld;
(5) stop precipitation power-off, cut off dewatering well gutter and cable;
(6) steel sleeve chock off cotton-wool and rapid setting cement;
(7) Fast Installation sealing ring and blind plate, and tighten with clip;
(8) sleeve pipe top is sealed with rapid setting cement, then welds dewatering well top seal steel plate, and shut-in well completes.
As mentioned above, although represented and explained the utility model with reference to specific preferred embodiment, it shall not be construed as the restriction to the utility model self.Not departing under the spirit and scope prerequisite of the present utility model of claims definition, can make in the form and details various variations to it.
