Abstract
The utility model relates to a plugging device for a basement precipitation well. The plugging device comprises a steel pipe body. The upper end of the steel pipe body is provided with a flange. The flange is provided with a sealing rubber ring and a sealing cover. The middle of an outer wall of a steel pipe is coaxially provided with a water stopping piece. The outer wall of the bottom end of the steel pipe is coaxially provided with a wellhead sealing steel plate. Concrete is fixedly installed on the wellhead sealing steel plate and coated with a waterproof layer. The plugging device is simple in structure, scientific and reasonable in design, reliable in sealing and capable of effectively preventing water leakage.
Description
Technical field
The utility model belongs to plugging device field, especially a kind of basement plugging dewatering well device.
Background technology
Big basement long construction period, from before soil excavation at least 20 days complete to basement roof earthing, need uninterrupted precipitation, after precipitation, by precipitation well head and basis handing-over position shutoff.Conventional way is first the water in dewatering well to be drained, and at once in dewatering well backfill rubble to absolute altitude at the bottom of foundation pad, use than the expansive concrete of the high strength grade of base concrete simultaneously and build to flat with basic epithelium.The weak point of doing is like this to produce constuction joint at dewatering well port part, brings the hidden danger of leaking.If there is seepy question at this position, cannot thoroughly effect a radical cure.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of basement plugging dewatering well device is provided, and this plugging device is simple in structure, design science reasonable, sealing reliably, effectively prevents from leaking.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of basement plugging dewatering well device, its plugging device comprises a steel pipe main body, install a flange additional in steel pipe main body upper end, O-ring seal and seal cover are installed on flange, the coaxial sealing piece of installing at outer wall of steel pipe middle part, at the coaxial wellhead sealing steel plate of installing of steel pipe bottom outer wall, on wellhead sealing steel plate, be fixedly mounted with concrete, application waterproofing course on concrete.
And the diameter of described sealing piece is 500mm.
And, application waterproofing course on the steel pipe between described wellhead sealing steel plate and sealing piece.
And described waterproofing course is BAC waterproofing materials.
Advantage of the present utility model and beneficial effect are:
This basement plugging dewatering well device, its plugging device comprises a steel pipe main body, install a flange additional in steel pipe main body upper end, O-ring seal and seal cover are installed on flange, the coaxial sealing piece of installing at outer wall of steel pipe middle part at the coaxial wellhead sealing steel plate of installing of steel pipe bottom outer wall, is fixedly mounted with concrete on wellhead sealing steel plate, application waterproofing course on concrete, the utility model is simple in structure, design science is reasonable, sealing reliably, effectively prevents from leaking.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below by specific embodiment, the utility model is described in further detail, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of basement plugging dewatering well device, its plugging device comprises a steel pipe main body 5, installs method 6 orchids in steel pipe main body upper end additional, and O-ring seal 7 and seal cover 8 are installed on flange, the coaxial sealing piece 4 of installing at outer wall of steel pipe middle part, the diameter of described sealing piece is 500mm.At the coaxial wellhead sealing steel plate 1 of installing of steel pipe bottom outer wall, on wellhead sealing steel plate, be fixedly mounted with concrete 2, application waterproofing course 3 on concrete.Application waterproofing course on steel pipe between described wellhead sealing steel plate and sealing piece.Described waterproofing course is BAC waterproofing materials.
Before foundation pad construction, the utility model is lain on precipitation well head, open seal cover, wellhead sealing steel plate center and dewatering well center-aligned.After foundation pad construction around the utility model construction waterproof layer, obturage by sealing compound, realize precipitation operation.In the time that precipitation is complete, will mount cover seal cover, finally exposed parts build 50mm thick with ground floor with the concrete of strength grade as topping.
