Abstract
The utility model provides a novel dewatering-well sealing structure. The lower end of a steel sleeve in the novel dewatering-well sealing structure is inserted in a well casing, a lower water stop plate installed on the outer side of the steel sleeve is connected with the upper end of the well casing, a fixing plate installed at the upper end of the lower water stop plate is fixedly connected with the outer wall of the steel sleeve, and a foundation pad is installed on the outer side of the fixing plate and the outer side of the lower water stop plate. A waterproof sealing layer is laid on the foundation pad and the fixing plate, the waterproof sealing layer is laid upwards along the outer wall of the steel sleeve all the time, and waterproof roll material and water stop steel plates are sequentially laid on the outer side of the waterproof sealing layer. A waterproof cushion layer and a cover plate are installed at the top of the steel sleeve, broken stone is installed in the well casing, and UEA concrete is installed in the steel sleeve. By the adoption of the novel dewatering-well sealing structure, construction difficulty in a dewatering process can be effectively reduced, progress of sealing of a dewatering well is improved, the problem of dewatering continuity in a foundation ditch during construction is effectively resolved, the situation that underground water has no influence is guaranteed during construction, construction quality is guaranteed, and engineering material can be effectively saved.
Description
Technical field
The utility model relates to building field, specifically a kind of novel precipitation well enclosed construction.
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.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of good to precipitation well sealing effect in the sole plate, and the novel precipitation well enclosed construction of convenient construction.
The technical solution of the utility model realizes in the following manner, insert in the well casing lower end of steel sleeve in its structure, the following seal plate of steel sleeve arranged outside is connected with the well casing upper end, the upper end of following seal plate is provided with fixed head and fixedlys connected with the steel sleeve outer wall, the arranged outside of fixed head, following seal plate is foundation pad, be equipped with waterproof sealing layer on foundation pad, the fixed head and described waterproof sealing layer is up laid along the steel sleeve outer wall always, the waterproof sealing layer outside is equipped with waterproof roll and steel plate for sealing water successively; The top of steel sleeve is provided with waterproof bed course and cover plate; Well casing inside is set to rubble, is set to the UEA concrete in the steel sleeve.
Waterproof bed course, cover plate that above-mentioned steel sleeve and top arrange pass through bolt.
Above-mentioned well casing internal diameter is identical with the steel sleeve external diameter.
The upper outside of above-mentioned steel sleeve is provided with seal plate.
The utility model has the advantages that:
A kind of novel precipitation well enclosed construction of the present utility model is compared with prior art, 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 construction, do not have 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 precipitation well in the construction provides a kind of constructing structure easily rationally.
