Description
Technical Field
The utility model relates to a dampproofing envelope suitable for secret factory building. The method is suitable for the moisture-proof enclosure of the underground powerhouse near the rock wall side of the hydropower station.
Background
The underground powerhouse of the hydropower station is positioned in underground surrounding rocks, and the surrounding rock walls generally have the phenomenon of water seepage and dripping, particularly the water seepage and dripping are more serious when the geological conditions are poor and the underground water develops; more power equipment is generally arranged in the hydropower station underground powerhouse, the requirement on the operating environment is higher, in order to ensure indoor dryness and tidy appearance of the underground powerhouse, a concrete or brick moistureproof wall is generally required to be arranged on the side close to a rock wall, but the construction period of the concrete or brick moistureproof wall is relatively longer, the construction interference with installation of a hydropower station unit is large, and the construction period is an outstanding contradiction in the construction stage.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: aiming at the existing problems, the moistureproof enclosure structure which is simple in structure, short in construction period and low in engineering investment and is suitable for underground plants is provided.
The utility model adopts the technical proposal that: the utility model provides a dampproofing envelope suitable for secret factory building which characterized in that: a support mechanism is arranged on the side, close to the rock wall, of the underground workshop, and a fireproof aluminum composite plate is arranged on the side, far away from the rock wall, of the support mechanism.
The support mechanism is provided with a support structure arranged around a rock wall, the side of the support structure far away from the rock wall is connected with a steel keel through a connecting piece, and the side of the steel keel far away from the rock wall is provided with the fireproof aluminum composite plate.
The fireproof aluminum composite board is fixed on the steel keel through steel screws.
The supporting structure is provided with a plurality of vertical concrete columns arranged around a rock wall, and a plurality of transverse steel beams are connected between adjacent vertical concrete columns.
The steel keel is provided with a plurality of vertical main keels and a plurality of transverse secondary keels.
The vertical main keel and the transverse secondary keel are fixedly connected at the intersection position through steel screws.
The utility model has the advantages that: the utility model has the advantages of being simple in structure and construction and simple to operate, can play effectual dampproofing enclosure effect through fire prevention aluminum composite panel, can satisfy operation stage environmental requirement, and the utility model provides a supporting mechanism and the form that fire prevention aluminum composite panel combines can effectively reduce the dampproofing enclosure's of underground factory building construction cycle, furthest avoids interfering with the construction of unit installation.
