Undesirable, become a difficult problem on building construction technology.
The measure the most generally used is to be cut out circular stalloy by workman's onsite application electric welding and have circle
The square tagger in hole is respectively welded in well head inner and outer wall, but has the disadvantage in that
1) on-site cutting error is bigger, it is difficult to realize 100% closely connected；
2) easily there is through welding phenomenon in inside and outside wall welding；
3) simple rely on weld seam to combine steel plate closure to be difficult to 100% airtight；
4) interface of welding fabrication is easily affected by chemical attack after for a long time, causes infiltration hidden danger.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of base pit dewatering well sealing device, this base
Hole dewatering well sealing device be possible not only to be arranged on precipitation well head conveniently and efficiently, and have strength and
Long-acting sealing effectiveness.
For solving above-mentioned technical problem, the technical solution of the utility model is: have capping and envelope skirt
Sealing cap, this sealing cap is enclosed within the suitable for reading of dewatering well, and this envelope skirt is welded on the outer wall of above-mentioned dewatering well, this
Outward, the water stop spacer between above-mentioned capping and described dewatering well it is lining in also including.
Further being improved by of described base pit dewatering well sealing device, described water stop spacer is posted by
Described capping.
Further being improved by of described base pit dewatering well sealing device, in described water stop spacer away from
The surface of described capping has annular groove, and the suitable for reading of described dewatering well is embedded in described annular groove,
Described annular groove and the interference fit suitable for reading of described dewatering well.
Further being improved by of described base pit dewatering well sealing device, fills out in described annular groove
Equipped with waterproofing unction.
Further being improved by of described base pit dewatering well sealing device, described envelope skirt and described precipitation
The mode using full weld between the outer wall of well seals fixing.
Further being improved by of described base pit dewatering well sealing device, described sealing cap is according to sizing chi
Very little one time punching molded.
Further being improved by of described base pit dewatering well sealing device, described water stop spacer is circular
Rubber water-proof pad.
This utility model is owing to have employed above technical scheme so that it is have the advantages that
Owing to sealing cap is one time punching molded according to shaping size, during installation, it is suitable for reading that sealing cap is enclosed within dewatering well,
And seal full weld around the borehole wall of skirt and dewatering well, in so avoiding capping and envelope skirt is respectively welded
The welding caused at precipitation well head is the tightest, the problem of easy through welding, and install not only convenient but also
Fast；Again due to be lining in round rubber water stop spacer capping and dewatering well suitable for reading between, round rubber
Water stop spacer is posted by capping, and dewatering well is suitable for reading simultaneously is closely embedded in annular groove, enhances anti-
Aqueous energy, further avoid infiltration hidden danger；Additionally, be filled with waterproofing unction in annular groove, keep away
Exempt from the poorly sealed problem caused due to dipped ring on well casing, further enhancing waterproof effect, and
Long chemical attack test can be stood, extend the waterproof time limit.

Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described in further detail.
First, referring to figs. 2 and 3, Fig. 2 is that the structure after base pit dewatering well sealing device is installed is cutd open
Depending on schematic diagram, Fig. 3 is the structural representation of base pit dewatering well sealing device stereoscopic-state.As shown in the figure
Base pit dewatering well sealing device described in the utility model includes having capping 2 and the sealing cap 1 of envelope skirt 3,
During installation, to be enclosed within dewatering well 7 suitable for reading for sealing cap 1, will weld between envelope skirt 3 and dewatering well 7 outer wall, this
Plant mounting means in the fixing requirement meeting between sealing cap 1 and dewatering well 7 simultaneously, in turn ensure that one
Fixed sealing.Based on said structure, at sealing cap 1 and dewatering well 7 liner suitable for reading water stop spacer
4, further enhancing the reliability of whole sealing device.
In the present embodiment, referring to figs. 1 to 5, Fig. 1 is that base pit dewatering well sealing device is not when installing
Structure cross-sectional schematic, Fig. 4 is that the structure section view after water stop spacer and waterproofing unction amplify in Fig. 1 is shown
Being intended to, Fig. 5 is the partial enlarged drawing of a-quadrant in Fig. 2.In figure, sealing cap 1 is according to shaping size once
Stamping so that capping 2 and envelope skirt 3 become an entirety, use the sealing cap 1 of said structure to overlap
Suitable for reading at dewatering well 7, define first water-proof system；Water stop spacer 4 is round rubber waterstop pad
Sheet, is posted by capping 2 inner surfacies, and in water stop spacer 4, the outer surface away from capping 2 has annular recessed
Groove 5, for increasing sealing, the suitable for reading of dewatering well 7 is embedded in annular groove 5, annular groove 5 with
The interference fit suitable for reading of dewatering well 7, with this, defines second water-proof system；Finally, in order to enter
One step strengthens waterproof effect, also for increasing the waterproof time limit, loads waterproofing unction in annular groove 5
6, evade owing to dewatering well is suitable for reading uneven, the sealing leak caused, also made whole foundation ditch drop
Well sealing device can stand long chemical attack infringement, defines the 3rd road water-proof system.
Accordingly, when assembling enforcement, load the one layer of waterproofing unction 6 annular at water stop spacer 4 in advance
In groove 5, and it is arranged on the suitable for reading of dewatering well 7, the just embedded rings connected in star suitable for reading of dewatering well 7
In 5, due to the sealing function of waterproofing unction 6, suitable for reading due to annular groove 5 and dewatering well 7 again
Use interference fit, therefore water stop spacer 4 all fits tightly with the suitable for reading of dewatering well 7 and outer wall, then
Sealing cap 1 is enclosed within the dewatering well 7 equipped with water stop spacer 4 suitable for reading, allows water stop spacer 4 be close to cover 2,
Now water stop spacer 4 liner is between sealing cap 1 and dewatering well 7, finally uses the mode of full weld envelope
The outer wall of skirt 3 and dewatering well 7 seals fixing, forms the three reliable water-proof system in road with this.
Above in association with drawings and Examples, this utility model is described in detail, common in this area
This utility model can be made many variations example by technical staff according to the above description.Thus, in embodiment
Some details should not constitute restriction of the present utility model, this utility model will be with claims
