Abstract
The utility model provides a precipitation well sealing structure in a foundation baseboard in the field of building engineering. The structure is characterized in that a steel cylinder is arranged on the upper part of a non-sand pipe; a foundation cushion is arranged at the outer side of the lower part of the steel pipe; a bottom fixed water stop plate, a rubber gasket , a waterproof layer, a rubber gasket and a movable circular steel plate with a bolt arranged on the upper part are successively arranged on the upper part of the foundation cushion and are sequentially fixed on the foundation cushion at the bottom; the bottom fixed water stop plate is fully welded on the steel cylinder; and a round sealing steel plate is welded on the upper part of the steel cylinder. Compared with the prior precipitation well sealing structure in the foundation baseboard, the utility model solves the problem of continuous precipitation in a foundation pit during the construction of a baseboard structure so as to ensure no groundwater impact during construction, thereby ensuring the construction quality, and therefore, the utility model has very good promotion and use value.
Description
1, technical field
The utility model relates to waterproof, the shut-in well structure of sole plate precipitation well in a kind of building trade, precipitation well enclosuring structure in specifically a kind of sole plate.
2, background technology
In building construction process, normally base plate construction finishes and can stop precipitation operation in the precipitation well when back concrete reaches certain intensity, then the precipitation well is carried out sealing operation, but adopt existing enclosuring structure to occur problems such as sealing effect is undesirable, work progress waste engineering material easily, become a technical barrier on the building construction technology.
3, summary of the invention
The purpose of this utility model is the technical barrier that overcomes in the above-mentioned construction, provides a kind of good to precipitation well sealing effect in the sole plate, and precipitation well enclosuring structure in the sole plate of convenient construction.
The technical solution of the utility model realizes in the following manner, its structure is by steel cylinder, bolt, foundation pad, no sandpipe, the bottom is seal plate fixedly, rubber sheet gasket, waterproofing course, movable annular steel plate and circle are sealed steel plate and are constituted, the top of no sandpipe is set to steel cylinder, the outside of steel cylinder bottom is a foundation pad, the top of foundation pad sets gradually and is the fixing seal plate in bottom, rubber sheet gasket, waterproofing course, rubber sheet gasket, the movable annular steel plate, the top of movable annular steel plate is provided with bolt, be fixed in successively on the foundation pad by bolt, the bottom fixedly the seal plate full weld on steel cylinder; The top of steel cylinder is welded with circle and seals steel plate.
Graded sand and stone, 100mm place to the top of steel cylinder UEA concrete pouring under the steel cylinder inner base bed course are filled by no sandpipe inner bottom part 100mm place to the steel cylinder inner base bed course.
Steel cylinder outer wall middle part is welded with fixedly seal plate of middle part.
Fixedly fixedly seal plate, movable annular steel plate and circle are sealed steel plate and are all selected the above thickness steel plate of 3mm for use seal plate, bottom at the middle part.
Adopt this constructing structure can effectively reduce difficulty of construction in the precipitation process, improve the progress that the precipitation well seals, the continuity problem of precipitation in the foundation ditch when efficiently solving the base arrangement construction, there is not influence on groundwater when guaranteeing to construct, guaranteed construction quality, can also effectively save engineering material, thereby application of the present utility model will be sealed the sole plate precipitation well in the construction provides a kind of constructing structure easily rationally.
