Background
Dewatering wells are generally used in construction of building foundations to drain accumulated water in foundation pits or concave areas. After the foundation construction is finished, the dewatering well needs to be plugged, so that the water leakage problem is prevented. At present, most of plugging of dewatering wells is to fill the dewatering wells with concrete directly and then weld steel plates at well mouths. The method not only has complex construction and influences the construction efficiency, but also is easy to cause water leakage phenomenon for underground passage structures with complex surrounding environment, high underground water level or river channels which are penetrated downwards. Therefore, improvements are urgently needed.
SUMMERY OF THE UTILITY MODEL
The utility model aims at prior art not enough, provide a precipitation well waterproof construction, not only can prevent effectively that the problem of leaking from appearing in the precipitation well, moreover, can simplify construction process, improve the efficiency of construction.
The technical scheme of the utility model is that:
a dewatering well waterproof structure comprises a steel sleeve, a sealing ring plate and a steel closing plate, wherein the steel sleeve is cylindrical, two ends of the steel sleeve are open, and the upper end of the steel sleeve is provided with an annular flash; the diameter of the steel sleeve is larger than that of the dewatering well, and the steel sleeve can be sleeved on the dewatering well and is arranged in the structural bottom plate; the steel casing plate is disc-shaped and can completely cover the upper port of the steel sleeve; the sealing ring plate is annular, and the width of the sealing ring plate is equivalent to that of the flash; the sealing ring plate is arranged between the steel door plate and the flash; the steel holding plate and the flash are tightly connected through a plurality of bolts.
Further, a water stop flange ring plate is arranged on the periphery of the middle part of the steel sleeve; and a water stop glue is arranged between the water stop flange ring plate and the steel sleeve.
Furthermore, a waterproof layer is arranged on the periphery of the lower portion of the steel sleeve.
Furthermore, a sunken hole is formed in a structural bottom plate around the upper port of the dewatering well, so that the upper port of the steel sleeve is located in the hole, and waterproof concrete is filled in the hole.
The utility model has the advantages that:
the utility model relates to a rationally, simple structure, convenient to use not only can effectively shutoff precipitation well head, prevents the problem of leaking, moreover, can simplify construction process, improves the efficiency of construction.

Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
As shown in fig. 1.
A dewatering well waterproof structure comprises a steel sleeve 8, a sealing ring plate 5 and a steel door plate 3, wherein the steel sleeve 8 is cylindrical, two ends of the steel sleeve are open, and the upper end of the steel sleeve is provided with an annular flash 1. The diameter of the steel sleeve 8 is larger than that of the dewatering well 13, and the steel sleeve can be arranged in the structural bottom plate 10 and is sleeved on the dewatering well 13. The steel casing plate 3 is disc-shaped, can completely cover the upper port of the steel sleeve 8, and is fastened and connected with the flash 1 through a plurality of bolts 4. The sealing ring plate 5 is annular, can be made of rubber and other materials, has an inner diameter equal to that of the steel sleeve 8 and a width equal to that of the flash 1, and is arranged between the steel plate 3 and the flash 1 to play a role in sealing. Preferably, the bolt 4 is a high-strength bolt and is welded to the flash 1 in advance.
And a water stop flange ring plate 7 is welded on the periphery of the steel sleeve 8 at the height 1/2, and a water stop glue 6 is tightly adhered between the water stop flange ring plate 7 and the steel sleeve 8, so that the upward seepage of underground water outside the steel sleeve 8 can be blocked. Preferably, the water stop glue 6 is an expansion water stop glue, and provides a waterproof function.
The waterproof layer is arranged on the lower portion of the steel sleeve 8, so that the upward seepage of underground water at the bottom of the structure can be blocked, and the waterproof effect is further improved. The waterproof layer sequentially comprises a protective layer 11, a waterproof coiled material 9 and a cushion layer 12 from top to bottom. Wherein the protective layer 11 is fine stone concrete; the waterproof coiled material 9 is a waterproof coiled material with double-sided adhesive asphalt base polyester tire pre-paved; the cushion layer 12 is waterproof concrete.
The structure bottom plate 10 around the upper port of the dewatering well 13 is provided with a reserved hole 2, so that the upper port of the steel sleeve 8 is positioned in the hole 2, and waterproof concrete is filled in the hole 2, thereby enhancing the waterproof effect.
The utility model discloses a use method does:
and in the construction process of a foundation pit and the like, a steel sleeve is sleeved on the dewatering well in advance, and a water stop flange ring plate is welded on the steel sleeve. Meanwhile, the installation and construction of the protective layer are carried out at the bottom of the steel sleeve. And after the foundation pit construction is finished, cutting off the upper part of the dewatering well, enabling the upper port of the dewatering well to be lower than the upper port of the steel sleeve, then installing the sealing ring plate and the steel door plate to the upper port of the steel sleeve, and completely sealing the dewatering well.
The utility model discloses can make the sealing operation of precipitation well convenient more and swift, improve the efficiency of construction. Meanwhile, through multiple protection measures, the waterproof effect can be greatly improved, and the waterproof requirement of the complex environment can be better met.
The utility model discloses the part that does not relate to all is the same with prior art or can adopt prior art to realize.
